Car Doors That Won’t Open

Cars! We love them, and we hate them when things go wrong. We can go for long periods of time without having any problems, but then something happens that we have to deal with or ignore. If your car door is stuck and you’ve ignored it, then it will feel good to finally get it working again.

To fix a car door that is stuck, you will need tools and patience. The first step is to figure out what is wrong and proceed from there. Here 5 ways to fix a door that won’t open on either side:

  • Lubricate the lock if it is sticking.
  • Use a new key or install a new lock.
  • Remove the door panel and inspect for issues.
  • Check to see if the latch is broken or malfunctioning.
  • Get a locksmith to help out.

Most of the complaints about stuck doors arise from car users that have older cars. If your car is reaching seven-plus years old, then this problem may be more likely to occur. We’ll discuss some remedies for fixing stuck doors that won’t open from the inside or the outside.

To save money, you can try fixing it yourself and improve your car fixing skills. Here are some things to try below.

Getting Started

Before you get started, investigate what the problem could be and determine how much time and effort you want to spend on fixing it. Do you have enough money, and does the weather permit working on your car outside?

Car doors can get stuck for many reasons. Older cars may have broken parts or parts that wear out. If moisture has made it into the door, it can cause corrosion or damage to parts as well. The car key or latch could also break or be damaged. The lock itself could get stuck.  

These are some reasons a door may not open where a professional might need to be called, like when working on newer car models. Lock security measures might make opening the door extremely difficult if the lock is not functioning.

How to Fix the Door?

1. Lubrication Method

If you are trying to turn the key while it is in the lock and it doesn’t open, you could have a sticking lock mechanism. The key may have some difficulty going into the lock, and sometimes it will turn a bit, but not much. Adding lubrication is likely the solution to this type of problem.

Moisture and dirt can get into the lock and make the lock mechanism stick. Lubricating the door lock with the help of graphite powder or a dry spray will help the frozen lock to work properly.

Procedure

(Be careful not to get any spay(s) on the paint )

  • 1. Blow out any dirt and grim with a can of compressed air (Amazon Link).
  • 2. Clean the lock using WD40.
  • 3. Lubricate the lock with dry lubricant or graphite powder.

A lubricant can work itself into all the moving parts of a lock and make sure it functions well. Using a cleaning spray, like WD40, will work short-term to help free the lock and make it work again. Later, applying a dry lubricant will help the lock remain functional for long periods. 

Another thing to try is to open the door from the inside. You might have a stuck mechanism that becomes unstuck by when using the inside door latch. If you suspect the latch is the problem, you can go to step 3 and inspect the latch after opening the door panel. 

2. Broken or Lost Keys

Sometimes your key may break or get worn out. You try using the key, but it just won’t work. At times shaking the key may work to open the door. You want to avoid shaking the key when opening the car door since this action may also make your door jam.

If you’ve lost your key, it’s best to use a spare key if you have one. Check out this article if you are still looking for them. Make a new key from the spare key so you have two. If you need to get into the car right now, you can try using readily available objects, like in this video. 

If your key is broken, make sure to use your spare key. You may need an emergency unlocking tool if you no longer have a key that works.

Eventually, you’ll need to replace your door lock (Amazon Link) with a new one so you can also get new keys. For some cars, this may be your cheapest solution.

3. Remove the Door Panel

If the above methods didn’t work, then looking inside the door might be the next best solution.

Remove the inside door panel and check to see if any part is broken.

Take your screwdriver set and detach the screws from the door panel. (Important note: It is better when you start removing the screws from the bottom of the car door panel.) Keep your screws organized, remembering where they go. 

Disconnect any electric connections attached to the door panel. Keep all the screws in a Ziploc bag or magnetic tray. Once you finish removing the screws, Try detaching the door panel. 

Slightly lifting it upwards on the panel and giving it a shake may help the panel come off. Each panel is a little different. Do some research to find out what works best for your car. 

Look inside.

Most cars have a plastic cover inside the door panel to prevent running water inside. Remove any plastic, look at the inside panel parts and see if anything looks broken. It could be a bent part or something that’s broken. 

With the panel removed, you can see what happens when you pull on the door handle. If you cannot open your door from the outside, then take a look at the metal rods on the inside panel. Are they operating correctly?

Fix it with a new part or improvise.

If you find the problem, see if you can use your tools to fix it. If it’s a broken part, see if there is a way to replace the part. Sometimes a junkyard may have the part you need. 

If you find yourself without a replacement part, think of a way to fix it with a workaround. Maybe use a metal coat hanger to replace a metal rod or use epoxy to secure a part. Ensure all the parts are working well and tightened enough to allow the door latch to unlock the door. 

Doing complex door repairs. 

If you’re facing a problem with a door that has many electronic parts, you’ll need to be careful to follow the steps outlined in a car repair manual. Some doors may have a locked motor that requires more research to troubleshoot. 

AD

Cars that have a power locking system use a door lock motor, which moves the rod to unlock or lock the door. If you want to investigate the problem with the motor, first check for a blown a fuse.

It might be fairly cheap to replace if the lock motor seems broken or doesn’t function when the power is on.

If you’ve locked your keys in the car with the car running, hopefully, you have a spare key or remote. Investing in a remote car starter may allow you to turn off the car remotely. 

4. Door Latch

Some people will slam the door very hard while closing it. This, when repeated many times, will cause damage to the door. Especially in the car door latch. Sometimes the latch will get stuck and not release. So you may need to analyze the cause of the problem.

An emergency unlocking tool (Amazon Link) may come in handy when trying to open the door. However, if it’s broken, somehow opening the inside door panel may be the only way to access any parts connected to the latch.

Some people try to use a coat hanger to open a door that is stuck. This could work, but you need to be careful not to scratch your car door or window. 

5. Final Call

If you are tired and fed up with trying yourself or just don’t have the time, call a qualified locksmith. They usually have an ample number of ways to open a locked door. Later you can consult with a mechanic to solve the problem permanently.

In certain cases, the whole locking system needs to be changed. If serious damage has occurred, like from an accident, the entire door may need to be replaced if you need it to function.

Fixing Technique

Before getting started, think about the tools you will need. Think about which tools you need, the time required, the help needed, and the money you are willing to spend, like paying for a locksmith (They can range from about $150). 

Secondly, check whether your car door is locked and can open from the inside. This might help you solve your problem more easily since you can open the door and access different areas more easily. 

The tools we suggest that may help are:

Safety Precaution While Working on Car-Related Problems

  • Switch off the car alarm. The car alarm might automatically go on when you get stuck inside the car or your car door is stuck. Informing the neighbors, if needed, about possible loud noises. If the alarm goes off, there won’t be any misunderstanding.
  • Make sure that you have your license and insurance with you while working on your car, especially if you are somewhere far from home. Having your car documents can help you if the police stop and ask you what’s happening.
  • Keep a first aid kit in your car in case any injuries occur or if you need to grab a band-aid.

Conclusion

Car doors that won’t open or close may just need a little maintenance. Good maintenance (like lubricating parts that need it) will prolong the life of your car door. Avoid hitting, kicking, or slamming when your car door is stuck or won’t close properly. Fix or lubricate parts as needed.

While working with the door panel, handle it with care, or else it might lead you to greater expenses. Getting good advice and doing some research before you start can be extremely helpful. Sometimes I find the answer to my car problems by doing research that solves my problem easily and avoids expensive and timely repairs. An expert’s advice or help can also be helpful in most cases. 

What Happens When You Jumpstart Your Car The Wrong Way: A Guide for Novice Drivers

Written by Chris in Cars

Jumpstart Car the Wrong Way

You do not need to be a genius to figure out how to jump-start a car’s battery. You simply need a car with a well-functioning battery and jump-starting cables. Connect positive to positive and negative to negative. Unfortunately, things may not always go as planned. There are some instances wherein you might not do it the right way.

When you jump-start your car the wrong way, damage to different car parts can occur. The battery, jumper cables, car electronics, fuses, and sensors could sustain some damage. Don’t forget yourself; burning yourself could also occur. 

That being said, jump-starting your car isn’t normally dangerous. We will explore how to stay safe and avoid dangerous situations. In addition, we’ll discuss what to do when an accident happens. 

Check out this video below for some common things that will happen if you don’t jump-start your car correctly:

https://www.youtube.com/watch?v=kVXf7B5UoI4

Jump Starting the Wrong Way: The Consequences

Each car is a little different, but each has fuses that help protect the car. If an accident does occur, most of the time, you don’t need to be concerned for your safety. The car may sustain some damage, but nothing serious usually occurs that would lead to serious harm.

Damage to Components

In the short video above, damage occurred to the fuse. Luckily nothing else seemed to be damaged. Some cars have spare fuses, so checking your owner’s manual might be helpful.

Damage to the electronic could be worse if more power was added. That’s why the 1st step to jump-starting is to turn off both cars and remove the keys.

Jumpstarting the car the wrong way will cause less damage when the cars are off. Switching the color, putting the red cable on the black (negative) battery terminal and the black cable on the red (positive) terminal, can send power where it’s not supposed to go.

The electrical system may be damaged, including sensors and fuses. The good news is that they can be replaced, and no permanent damage is done.

Damage to Battery

If a battery was connected the wrong way momentarily during a jump start, there would likely be a small amount of damage. But, if the connection persists for a while, the electrical current doesn’t have anywhere to go, and damage to the battery is likely to occur. 

The result of incorrectly connected batteries is that heat is created, gases are generated, and dangerous situations can occur. In this case, I am referring not only to the dead battery that is being jump-started but also to the battery from the rescue car as well.

The result of these two batteries connecting the wrong way could melt/damage either battery. If you have lead-acid batteries, which are the most common type of car batteries, hydrogen gas could be discharged.

This happens when the casing of the battery cracks a bit because of the pressure of the hydrogen gas. If gas escapes, it could explode in this type of situation. If you notice any dangerous situations, get far away (100 ft+) from the cars as soon as possible.

Most people will notice a larger spark when connecting the wrong way (possibly a smaller spark when connecting correctly)  and decide not to connect the cables that way anymore. This dangerous situation usually won’t occur with most people. 

Damage to Jumper Cables

Like the previous situation, incorrect contact with a jumper cable between two batteries for a time will heat up your jumper cables. The wires will heat up and may get damaged.

Strong cables may handle the heat better, but some lightweight cables could start to melt/burn when exposed to this amount of heat. The clamps will get hot, and the solder might not hot the wires securely anymore.

If you notice the heat from the cables, it’s best to disconnect them safely and recheck for the correct and secure connections. 

Damage to Alternator

Sometimes a car has some components that might be on during a jump start. Lights may be on or a stereo. A component that is on might be using the alternator. The alternator can then get a surge or power that can cause damage. 

Because of the high electrical current, which can be too much for many parts of your car to handle, the alternator could overheat. When there is an issue with an overheating alternator, other parts may be affected as well if using the alternator. 

It’s a good idea to make sure that everything is turned off and that anything that might be connected directly to the battery terminal, such as a car alarm, is disconnected. 

To sum up, turn everything off no matter what it might be, disconnect any device that may be connected to the battery, and be aware of items that may be automatically turned on in some situations, such as a radiator fan to cool your car after it is turned off. ​

If your car doesn’t start, put safety first, and you’ll save yourself large repair bills, and you’ll make sure no harm comes to you or anyone else.

​

How to Solve any Problems Created?

From the short video shown in the introduction, one solution is to change the fuse. 

The fuse can get burnt because of the extreme heat resulting from the surge of electricity. You’ll need to check your fuses and select the fuse(s) that may be associated with the car battery. In most cases, it is the powertrain fuse.

In some cases, the fuses may not be the only electrical part affected. If the alternator is damaged, it may need to be replaced, and it could affect the components that were connected to it. 

If the electrical current is able to get to the car’s computer system, you may need to replace that as well. 

Sometimes the battery is also damaged and no longer functions. It will need to be replaced as well.

Tips When Jump-Starting your Car

In most cases, jump-starting a car will be safe to do, but to prevent any problems, follow the guidelines outlined below:

Steps to Take

  • 1st – Cars: ensure cars are not touching each other
  • 2nd – Cables: Untangle and clean off any grease from the cables
  • 3rd – Electrical systems: Turn off the cars, remove the keys, and ensure all electrical systems are off, including the lights 
  • 4th – Cables: Connect the cables by:
    • 1. Connect the (+)positive cable clamp to the dead battery (+)positive terminal.
    • 2. Connect the other (+)positive cable clamp to the donor battery (+)positive terminal.
    • 3. Connect the (-)negative cable clamp to the donor battery (-)negative terminal.
    • 4. Connect the (-)negative cable clamp to the dead battery (-)negative terminal.  OR, to be extra safe, Connect the (-)negative cable clamp to the ground on your car away from the battery. (If any gas from the battery is leaking, and a small spark occurs, an explosion could occur.)  
  • 5th – Turn on the donor car. Let the dead battery charge for 3-5 minutes. (It depends on how drained it is.) 
  • 6th – Try starting the dead battery car. If it works, keep it on and drive it for about 30 minutes to help recharge. If it doesn’t work, you could try charging it a bit longer and try checking for good connections, as this may be why the battery is not charging. Another thing to try is using a different ground point.
  • 7th – After the dead battery car is running:
    1. 1. Disconnect the (-)negative cable clamp from the dead battery (-)negative terminal OR ground on your car.
    2. 2.  Disconnect the (+)positive cable clamp from the dead battery (+)positive terminal. You can place them on the ground making sure they don’t touch. 
    3. 3. Disconnect the (+)positive cable clamp from the donor battery (+)positive terminal.
    4. 4.  Disconnect the (-)negative cable clamp from the donor battery (-)negative terminal.
  • 8th – You are ready to go if everything is working well.

Avoid

  • Avoid charging vehicles or machinery that have larger batteries than you or that require more power. Regular cars and trucks should be fine most of the time. 
  • Make sure the cables do not come in contact with any metal surfaces, with each other, or with your skin as you attach them and detach them. 
  • If your battery is cold/ frozen, don’t try to jump-start.
  • If the battery is damaged, cracked, or leaking, don’t try to jump-start it – get a new battery.

Additional Tips

  • Take a look at your jumper cables and make sure that they are in good condition. They must be free from rust. If they are already worn out, even if you connect the clamp on the right terminals, it might not work well.
  • Read the manual before you start. If you may have information to help, you jump-start your car the right way for your specific model. For instance, newer car models might need to attach lugs before you jump-start.
  • Make sure that the car is in the park. The cars should be out of traffic and avoid any dangerous parking situations.
  • Protecting your hands with gloves and eyes with goggles could help avoid any injuries if something goes wrong. 
  • Perform an inspection on both of the batteries before you start. Clean the terminals if needed to create good contact points for the cables.

Conclusion

When you jump-start your car the wrong way, there are many things that could possibly happen. The battery, jumper cables, and electronics will be damaged, including the fuse and the sensors. There is even a risk of explosion when the problem is at its worst. Nonetheless, most of the time, the problem won’t be too severe and nothing that could cost an arm and leg.

Once you realize that you did the wrong thing, you may be able to fix the problem on your own. In most instances, you need to check the fuse. Chances are, one of them is burnt. You can buy a replacement for this, and your car will be up and running in no time.

Have you ever tried using a battery charger to get your car to start? This might help you figure out if your battery is salvageable or not. If you are still not sure why your battery is dead, try reading this article. 

Why Is My Transmission Shifts Hard When Hot?

Written by Chris in Auto Engines,Auto Parts,Cars

Transmission Shifts Are Hard

A vehicle’s transmission is able to transfer power from the engine to the car’s tires. Its main purpose is to control the speed at which the tires turn. It controls the power that flows from the engine to the driveshaft. This particular part of your car goes through quite a bit of stress, just like many engine parts of the car. The stress is due to the friction and heat generated because of the movement of different components.

Transmissions shift hard when hot because their parts tend to get damaged, worn, and malfunction under high heat levels. Your transmission needs fluid to keep cool, and if the fluid leaks, then it may create more heat and pressure. The fluid may thicken and get burnt, and then it no longer functions to cool and lubricate, making the transmission shift hard. 

There could be several reasons for hard shifting, but a hot transmission may be one of the leading causes. To find out what problem you have with your transmission, we’ll take a look at some common issues that lead to higher levels of heat and pressure in a transmission. Avoiding replacing the transmission may be important to you because it is quite expensive.

Some of the Most Common Transmission Problems

1. Low or Leaking Fluid

Leaking-Fluid

Whenever there is a leak, it can start damaging the transmission. Leaking transmission fluid is among the most common reasons (heat) behind transmission breakdown. Automatic transmission fluid (ATF) cleans, lubricates, and seals the transmission.

Checking the fluid level regularly (unless you have a sealed transmission) and changing it when the owner’s manual says it will help prevent problems later. If you suspect a leak, find where it is leaking from (possibly because of a damaged seal) and get help fixing it or replacing the damaged seal yourself.

Reduced amounts of transmission fluid (or not changing the fluid) can create unhealthy conditions for your transmission. Look for dark/burnt fluid when checking the fluid levels. If the fluid is light brownish or dark brown/black, it needs to be replaced.

Try wiping the fluid on a white paper towel to see what color it is. If you notice a pinkish color, then it’s still in good condition.

If you have a leak, try to fix it right away. If the color is dark, try to replace it right away.

(Warning: If your car ran with burnt transmission fluid or low fluid for a while, the damage probably occurred to the clutch, even if you never noticed it. Changing the transmission fluid will clean out particles that may have filled in the gaps of a worn-out clutch. The clutch will then start to slip because the particles aren’t there to help grip. You’ll need to replace the clutch parts that are worn and anything else that may have been damaged.) 

So, it is recommended to fill or replace the transmission fluid when needed. Fix any leaks or damage using a professional unless you’ve got the skills needed. 

2. The Slipping of Gears

gear

The automatic transmission makes use of a series of gears that help transfer the right amount of power for speed, climbing hills, and going in reverse. A gear set consists of multiple small gears. Usually, it has a sun gear at the center and three planet gears around the sun gear, and a ring gear surrounding the planets.

As the transmission changes from one gear set to another, a shift is performed. The shift can be automatic or manual.

If the transmission slips, then the gears are not engaged. It may seem like you’re neutral. The reason may be because of a worn clutch or low hydraulic pressure. To find out more, check the issues we talked about, reason 1 above. Also, avoid driving with a slipping clutch since accidents could occur.

3. Dragging Clutch

Dragging-Clutch

A dragging clutch occurs when the clutch disk won’t separate all the way from the flywheel. Since it won’t disengage, changing gears will not work. 

This may happen when pressing the clutch pedal and the cable going to the transmission has too much slack. Adjusting the cable can fix this issue. If the clutch disk can’t move away from the flywheel, it will just continue to turn to provide torque to the gear.

If you hear a grinding noise every time you change the gears, this may be a dragging clutch that disengages almost all the way, but not quite.

In some cars, the clutch only starts to drag when the transmission gets hot. This, too, is a cable adjustment issue usually. Repairing these issues is usually inexpensive unless damage has occurred. This quick fix involves adjusting the cable, so the clutch can separate. 

4. Transmission Noisy in Neutral

neutral

When a transmission is noisy in neutral, it might be time to consult a mechanic. Some of the possible reasons could be the transmission lost fluid and ran hot, causing damage to the clutch, using the incorrect transmission fluid, worn-out gears, or a bad release bearing. 

  • First, check the fluid and refill/change/flush if needed. Test the transmission by taking it on a road test. Any noises? (See: article for more info)
  • Next, pull over and put the car in neutral. Keep the clutch pedal to the floor and listen for any noises. If you hear noises, the release bearing could be the problem. Now, release the clutch pedal and listen. If you still hear noise in neutral with the clutch pedal released, then the shaft bearing may be the problem. 
  • Last, if adding the fluid doesn’t work, get a professional to take a look. It may need replacement clutch parts, bearings, or gears.

5. Burning Smell

smokey

The burning smell mostly arises when the transmission fluid overheats. Transmission fluid works by keeping the parts cooled and lubricated so that they don’t get damaged. The transmission generally gets hot if there’s not enough fluid.

The result could be damage and higher friction. Build up of debris and burnt fluid sludge in the valve body can create clogs. Clogs can make shifting more problematic and getting into gear more difficult. Flushing your system may make things worse since the new fluid will clean the sludge, and too much will clog the valve body.  (See: Video)

Flushing is a good idea when you have burnt transmission fluid; just make sure the valve body is also cleaned. A mechanic may be needed to check out what’s going on. 

6. Checking the Engine Light

Checking-the-Engine-Light

The check engine light, which is located on the car’s dashboard, will tell you if there is something wrong with the engine or transmission.

There are many sensors all around the engine, and these sensors inform the car’s computer of any unusual activity. The sensors on transmission can sense the slightest vibrations and jerks that we can’t even feel. Another sensor monitors the heat of the transmission fluid. If you see the light flashing or on consistently on, take time to check your fluids.

See a mechanic or get an OBD2 scanner to check what the check engine light means.

7. Does not go into a Gear

a-Gears

Sometimes the car does seem to want to go into gear. You might try going into reverse or other gears, but the transmission doesn’t seem to respond at all. 

There could be a number of reasons for the car not going into gear. Here are some reasons:

  • The thickness of fluid can be incorrect. The hydraulic pressure needs to be correct to shift gears.
  • The linkage of the clutch. Adjusting the cable/linkage that attaches to the clutch pedal may help.
  • Heat and low levels of transmission fluid can create shifting problems.

Using an OBD2 scanner can be helpful in identifying the reason for the shifting problems. It can help identify the root problem(s).

8. Grinding or Shaking

Most of the time, our cars run smoothly without any jerking, shaking, or grinding noises. These issues may be due in part to problems with the car’s gears. 

If you have a manual transmission and you hear grinding noises as you shift, the gears could be damaged. Another reason for grinding could be the clutch is damaged and is having difficulty helping the car to shift into gear. Heat can cause damage to the gear synchronizers, or they may have worn out due to age. An adjustment or replacement of the clutch might resolve this issue. 

An automatic transmission acts differently. In this, it may not make a grinding noise, but it may take time to shift into gear when compared with normal operation. When the problem gets worse, the transitions into the next gear become shaky and more jarring. 

Consult your mechanic to help with diagnosis if you’re unsure what is going on with your car. Worn gears or clutch might be the reason for the vibrations your feel and the noises you hear.

9. Whining, Clunking, and Humming

Mechanical-Transmission

Transmission shifts hard when hot, and the sound varies between different models. The sound that you hear may be a whining, humming, or buzzing noise. How the transmission fluid acts under extreme heat is different from the normal operating temperature. 

Higher temperatures mean higher pressure, and although transmission fluid works well at high pressure, the heat may start to cause the fluid to burn if pressure and heat are not relieved. Under high pressure, shifting may be more difficult, so noises may occur.   

The sounds generated by a manual transmission may be more mechanical, abrupt, and louder sounding. When you shift a gear, a clunking sound may occur. The differential or constant velocity joints may also be the source of these sounds if the clunking is coming from the underside of the car.

10. Lack of Response

Sometimes while driving a car, it does not go into gear right away. What should happen the moment a car shifts from park into drive? It should go into the proper gear immediately. 

For automatic transmission vehicles, a delay when the vehicle is shifting is usually a transmission-based concern. In manual transmissions, there may be a similar response, but after shifting into gear, the engine RPMs will surge. The car remains still, but the engine continues to rev.

This means you may have a clogged valve body. The clutch may also not be engaging for some reason, possibly temperatures are too high.  Low pressure could also result in delays when shifting. 

Check your fluid levels and do a scan with your OBD2 scanner to see if there’s anything showing up that’s creating these issues.

What is Diesel Engine Oil?

benefits-of-using-synthetic-oil

Diesel oil is the oil you use to lubricate your engine if you have a car or truck that runs on diesel fuel. It should not be used in gas engines, although some oils on the market say they are OK to use in either vehicle type.

When changing diesel engine oil, make sure to look at the oil cap. This will usually tell you which oil your car needs; otherwise, look at your owner’s manual. Diesel engines are designed differently than gasoline engines, so you should choose an oil that is specifically designed for your diesel engine.

The process of choice might come down to regular oil, synthetic blend, or full synthetic. Full synthetic is usually the best option for protecting your engine. It can handle higher temperatures and coat parts better than regular oil.

What’s the Difference Between Diesel and Gas Engine Oil?

Diesel Engine OilGas Engine Oil
Made from oil and additives – These additives can help deal with acidity and carbon.Made from oil and additives – These additives can help deal with moisture and tar
Higher anti-wear load. It uses zinc dialkyl dithiophosphate for this purpose.Lower anti-wear load. A gas engine’s catalytic converter can’t handle diesel oil
Higher viscosity generallyLower viscosity generally
More cleaning additives used to deal with extra combustion by-productsLess cleaning additives needed

Diesel engine oil is very similar to gasoline engine oil. Both have base oils that are formulated with a variety of additives to change particular oil properties. The difference between the two depends on the number of additives that are used.

Diesel engines absorb more carbon, while gasoline engines tend to absorb more moisture and tar. Diesel engine oils contain a higher amount of dispersants and more anti-wear additives. Also, diesel requires higher viscosity in the oil, unlike the gasoline engine, which produces more heat. In sum, diesel engine oils contain additives that help deal with the harsh conditions inside.

Advantages of a Diesel Engine

Having a diesel engine has a lot of advantages compared to having a gasoline engine. This section will discuss why it is more efficient and why people prefer diesel engines.

  • Older models of diesel engines create a lot of noise and are very costly to maintain. However, modern ones are quiet, and they require less maintenance.
  • Unlike gasoline engines, they are more reliable and rugged.
  • You might notice that there are no spark plugs in your diesel engine. The reason for this is that hot compressed air is used instead. So wires and spark plugs aren’t needed, lowering some maintenance costs.
  • Diesel engines are now widely used in most kinds of transportation, such as cars, trucks, and buses. They are also used in the aircraft industry. They are used for the combustion engines of some trains as well.
  • Armored and military vehicles also use this type of engine because they are unlikely to catch on fire. This means that it is safer to have in some cases.
  • Aside from cars, heavy equipment, tractors, and other industrial applications also use diesel engines.
  • Diesel engines can provide higher miles per gallon. This is one reason it’s preferred for heavy-duty transportation and use in large machines. It also provides more pulling power at lower speeds, which is great for heavy loads. 
  • Though it may be more expensive than gasoline, diesel has a higher density, which means more energy can be extracted.
  • Diesel is proven to be more efficient and cost-effective than gasoline. With proper maintenance, it can be a great vehicle to own with a long lifespan.

Factors to Consider when Choosing the Best Diesel Engine Oil

To decide effectively, you have to know what makes the best diesel engine oil. This section will discuss some of the factors you might want to consider when making your choice.

synthetic-oil

  • Viscosity: Look at the viscosity grade shown on the label of the oil manufacturer. This is very important, as it will determine the starting temperatures of your engine. You have to pick the lubricant shown on your car’s oil cover or shown in the owner’s manual. 
  • Cost: The price of your diesel engine oil matters. You need to decide which oil fits your needs and budget. There are cheaper ones and ones that cost more. Research might help you decide if a certain type works well in your vehicle type. I would recommend synthetic oil because it performs the best. Sometimes your local store will have a lower cost vs. internet.
  • Cleaning Capability: Cleanliness is an important factor to consider when changing oils. You have to make sure that you choose the diesel oil that works well with your engine.
  • Compatibility: Not all engine oils are formulated or suitable for diesel engines. As discussed above, the gasoline engine also requires a different type of lubricant. You have to make sure that the diesel engine oil is compatible with your engine.
  • Wear Protection: The diesel oil you pick should not cause damage to your engine. Instead, it should provide your engine with maximum wear protection.
  • Versatility: Choosing a multifunctional diesel engine oil is a choice you might make. Then you can utilize it across a number of vehicle types.
  • Efficiency: It is also a good idea to consider how the engine oil will help with fuel efficiency.

What Are The Major Causes And Solutions Of Limp Mode?

Written by Chris in Auto Engines,Auto Parts,Cars

Limp Mode

If you have experienced a loss of power while driving, but later, the car’s power comes back when you restart the car, you may have just experienced your car’s limp mode. Limp Node is most likely to occur when you are driving at high speeds or accelerating quickly. Your car’s computer wants to protect you from causing damage to your car’s engine.

Limp mode is the safety feature built into many cars to protect the engine from damage. If your pushing your engine to the limit, the limp mode might be activated to prevent damage. Sometimes the computer will put the car in limp mode when it’s not necessary. Sometimes, just restarting the car after waiting 15 seconds will take you out of limp mode. Here are some major causes of Limp Mode:

  1. Transmission Issues
  2. Error in the Boost Deviation of the Car
  3. A Problem in the Cars Wiring System
  4. Leakage in the Battery Acid of the Car
  5. Modification to Your Car

If you notice the check engine light flashing on the instrument panel, this may be an indicator of limp mode. One way limp mode tries to protect your engine is by lowering engine power levels.

When I notice my car is in limp mode, it is my car’s way of saying, “Hey, your car might be in trouble, check it out as soon as possible.” The trouble might have occurred in the car’s transmission, computer, sensors, fluids, or wiring. To figure out what is going on, continue reading about possible problems and solutions.

Definition: Limp Mode

Let’s take a look at what limp mode is exactly:

The car has several computer-like modules that can detect problems. If one of these modules decides there’s a problem, it will try to prevent damage, sometimes by lower power or preventing the car from shifting into a particular gear.

This results in problems driving the car normally. The computer modules are trying to get you to fix the problem and will usually warn you with the check engine light. You are in ‘Limp Mode.’ 

If the check engine light is on, this doesn’t always mean limp mode, but it’s important to check. 

Now that we have a general idea of what limp mode is, let us consider its main causes and some solutions:

Cars have an ECU or electronic control unit that controls the electrical systems in your car. Here are some parts of the ECU: the engine control module, the transmission control module, the braking control, the central timing module, and the suspension control module. 

When a car’s computer system (ECU) detects an engine problem, a sensor issue, a braking problem, or it detects trouble in the transmission, it can protect the car by using limp mode. A trouble code is stored for you or a mechanic to look at if you have a code reader. 

The computer system generally does a great job ensuring the smooth operation of your car. It’s constantly monitoring the car’s smooth performance, checking for errors and sensor issues, and comparing data. Once any of the sensors indicates something out of parameter, it may alter the car’s behavior, ensuring damage doesn’t occur.

If a driver has made modifications to their car, the computer may not understand and place the car in limp mode. Sensors or wiring could malfunctioning as well. To fix this, first, we must investigate the possible problem. 

To find the precise causes of limp mode, get your gloves and gear ready:

OBD2 scanner

AD

The limp mode can prevent engine damage or prevent you from normal driving if nothing is wrong. Finding out the problems takes using a code reader or going to a service station.

If you have a code reader (OBD2 scanner), you can look into why the car says it is causing the difficulty and try to fix it if needed.

If you don’t have a scanner, it may be difficult to determine the precise problems, but a visual inspection might show low fluids, loose wires, loose parts, or damaged parts.

Major Causes of Limp Mode

1. Transmission Issues

transmission-issues

When the transmission control module finds an issue, possibly due to your car’s transmission getting interrupted or damaged, or it might detect strange sensor readings, it may put the car into limp mode.

Transmission Control Module

AD

The computer reads many sensors, but if one is not working, this loss of communication will generate a code, and the check engine light should go on.

2. Error in the Boost Deviation of the Car

If you get an error from the code scanner that indicates a boost deviation, you might have a bad sensor or a fuel pump problem. Investigate the code error and find the common reasons why the code usually occurs. 

Pressure Sensor

AD

If you feel a sudden and abrupt pause in the car, this may mean that limp mode has set in and taking control of systems that might cause damage if used. 

Checking the fuel pump, sensors, electrical connections, vacuum lines, or anything that could clog is a good idea. 

3. A Problem in the Cars Wiring System

cars-wiring-system

If your car is older, drives in bumpy areas often, or has had a leak, you’ll need to check your wiring for problems when your car goes into limp mode.

Wiring Connectors

AD

Look at the OBD2 scanner code, if you have one, and start looking at the wiring for the part that is indicated on the code.

The wiring inside the car’s hood is prone to corrode, break or tear. This can cause many electric problems to occur. Connect/replace any wires if needed.

4. Leakage in the Battery Acid of the Car

Photo Credit: http://www.audizine.com/forum/showthread.php/561015-Limp-Mode-ESP-light-EPC-light-P2138-Throttle-Pedal-Position-Sensor

Car batteries are important for your car’s electrical systems and provide power to your electronic control unit (ECU). If they either leak or are completely drained, the car’s computer system can have problems.

Car Battery

AD

This common problem may occur due to damaged wires or memory loss in the ECU. Battery troubles can cause wires to corrode, voltage fluctuations that might damage electronics, and loss of power to the computer.

Replace the battery or wiring if needed. Sometimes a simple cleaning of contact points can solve the problem.

5. Modification to Your Car

turbo charger

Many people like to modify their cars. They install new parts so their car will perform better. Aftermarket parts may not fit within the parameters set by the ECU electronic control unit. 

Turbo Charger

AD

Some people choose to modify their car and ignore the check engine light or reset/clear limp mode warnings from the car.

Sometimes they use an OBD2 scanner to clear codes and get their car working normally again. While this may not cause engine problems, there’s a possibility it could.

6. Solutions – Do it Yourself or Get Help

DIY or Mechanic

Do it Yourself

Understanding why your car’s check engine light is on or limp mode has occurred can bring a lot of relief. You better understand what is wrong and can work towards fixing it. 

Getting an OBD2 scanner to find out what codes are showing up can help you decide what to do next. It is usually easy to use and sometimes helps with practical information on the next steps to take. 

Another reason you might want a code scanner is to reset or clear codes that no longer apply. This will stop the check engine light from flashing, so do this only if you’ve fixed the problem and you are sure everything is working.

A visual inspection of your engine might also reveal information about the cause of your limp mode. Be sure to check for leaks, wire connections, and loose parts. Cleaning around hoses and connections might reveal what’s going on. 

If it’s a simple fix, like replacing a hose or a sensor, then I suggest doing it yourself. If not, get help.

Get Help

Going to a mechanic is the right thing to do when you have little to no experience fixing your car’s issues. Some items may need fixing and others replacing. A mechanic can read the codes and generally knows best what should be causing the problem, so you don’t need to spend extra money.

A mechanic is helpful when solving multiple problems since they understand how car systems work together.  

You may want to do some research and then decide if your limp mode activating means there’s a minor issue and nothing really wrong with the car or if it’s a serious issue that needs professional help. 

Start Today

Whether you fix it yourself or get help, try not to take too long to solve the problem. If your car has engine problems, driving could cause more problems. Usually, you want to stop driving the car and get it fixed.

Inspecting your car regularly or getting it to service for regular maintenance can catch issues before they become a problem. ​

With the computer systems in your car, you’ll have powerful information that you or a mechanic can use to diagnose and fix limp mode issues. 

Conclusion

If my truck were in limp mode, I would probably take it to a mechanic and then get a scanner so I would be more informed the next time a problem occurred. That being said, getting a scanner before might be a good investment, at least for some peace of mind.

Cars today have so many sensors and control modules that you’ll need to carefully consider whether making a repair is the right call after you’ve looked up the code and found out what’s wrong. 

The more research you do, the more confident you can diagnose and fix problems. And if you’re not confident enough, a professional can always get it repaired. I hope you found this article helpful, and for help with other car issues, head to Drivinglife.net.

Useful Information about the Auto Parts

1. Battery

Problem-with-Wrong-Battery

The battery in a car is rechargeable. It supplies power (electric energy) to the car. Normally this battery is used to help provide power to start the car, and then it is used only when extra power is needed. The car battery alone can’t supply power to all the electrical systems. The alternator does this.

The battery is connected to your lights and car accessories, like the radio, when the engine is off. Leaving the lights or radio on too long will drain the battery. If you don’t leave it on too long, your car’s battery will recharge during about a 30-minute drive.

A completely or partially (below 10.5 Volts) drained battery is not good. It causes damage to the battery. It is advisable to turn off car lights and accessories soon after the car engine has stopped.

Check the battery every 6 months to see if the terminals need cleaning and cleaning if needed.

2. Brakes

Usually, your car has two kinds of braking systems. The first one is the brakes pedal that you use to stop the car as you press on it with your foot. The second break system is the emergency break. It works independently from the pedal and sometimes looks like a rod you pull up on or a small pedal you press down on. 

Modern cars have hydraulic braking systems. They use pressure applied at the brake pedal to pressurize the brake pistons, which helps apply force to the brakes. Regular care should be taken to replace brake pads when needed and maintain parts in good working order. This can save your life as well as save your money.

3. Axle

AD

The axle is a bar or shaft used in turning the wheels. The transmission helps turn the axle, which turns the wheels. There is sometimes a front axle and a back axle that usually has a differential in the middle that joins the front pair of tires and back pair, so they move at the same time. Since an axle is a solid metal, it is difficult to break it.

If more weight is added, the turning capacity of the axle will drop down. The worst enemy of an axle is rust. It gradually leads to faulty performance sometimes; it also causes a breakdown. Cleaning the undercarriage if salt is used on the road and driving carefully on rough roads will protect your axle.

4. Fuel Injector

AD

This small part helps provide fuel to the engine. It uses a nozzle to deliver just the right amount of fuel to the combustion chamber. It is electronically controlled and helps with fuel efficiency.

The efficiency of diesel and gas engines has been increased over time through the use of fuel injectors over time. A clogged injector might cause poor idling and lower engine performance. If you clean the fuel injector, then your car may perform better.

5. Piston

piston

An average car will have four to six pistons in the engine. Pistons move when an explosion of gas occurs in the combustion chamber. As the pistons move, they turn the crankshaft, helping the car to deliver power to the tires, so the car can move.

The speed of the engine is directly proportional to the moving pistons. When fuel and air mix together and enter the combustion chamber, they are ignited by the spark plugs, creating an explosion that moves the piston. These pistons are cylinders that move up and down.

The faster pistons move, the more RPMs (Revolutions Per Minute) your car has. Running your car too fast can create problems with your pistons. Like the fuel injectors, pistons can get dirty and may need cleaning to perform their best.

6. A/C Compressor

AC Compressor

The air that is blown inside your car’s cabin can be cold. The A/C compressor is at the heart of this process. It compresses refrigerant, so the refrigerant can change from a gas to a liquid. When it’s gas, it can absorb heat, making the air cold as it blows over it. 

The AC compressor can operate well as long as there are no leaks in the system or other problems, like a broken radiator fan. If you get your car serviced regularly, they should check the AC system. If not, make sure to check it yourself. Damage can occur if the A/C Compressor encounters different issues, like refrigerant leaks.

7. Radiator

AD

The radiator is used to help the engine cool down so it can operate without overheating. It cools the radiator fluid that goes through the engine, where it is heated up. As it travels back to the radiator, the heat is transferred to the metal fins, and air as the fan blows over it.

A radiator keeps your car engine running at normal operating temperature. The coolant (antifreeze) in the radiator can change the boiling and freezing point of the water that is mixed with it (normal 50% water and 50% antifreeze).

The radiator can also send hot coolant to the heater core in your car cabin to heat up your air on cold days. To maintain your radiator, always make sure to have a water and antifreeze mix to prevent rust, and check for leaks if needed. Hoses and connection points are also areas to look at if you suspect a leak.

Lastly, if the radiator has dirt or particles covering the metal fins, make sure to clean it off. 

8. Engine Fan

AD

Fans are known for being very reliable. Your car’s fan cools the radiator (with antifreeze inside) and condenser (with refrigerant inside). This helps the engine and AC system maintain the proper operating temperatures. 

To maintain the fan, check for anything that could block the fan. The engine fan can blow particles into the fins of the radiator and condenser, blocking airflow. Clean off any debris from the metal fins of the radiator and condenser to prevent overheating.

9. Clutch

AD

The clutch is a mechanism that helps to transfer power from the engine to the transmission. In a manual transmission car, also known as a stick shift, the clutch is operated by the clutch pedal. The clutch pedal is located on the left side of the other two pedals.

https://www.youtube.com/watch?v=_hKvS6xTC0E

When you step on the clutch, the power from the engine is no longer going to the wheels. This allows you to change gears and increase or decrease the power and speed of the wheels. 

The clutch helps with the smooth transfer of engine power to the transmission, so the transmission can deliver power to your tires. If you change to a higher gear, the clutch helps you change which gears are used in the transmission, providing faster speeds.

The usage of a manual transmission (stick shift) gives you more control over the vehicle. When compared to an automatic transmission, a manual transmission can be cost-efficient and can be easier to fix. To maintain your clutch, learn to use it correctly and drive at normal speeds. 

10. Car Jack

Car Jack

A car jack is a simple device that helps to lift the car when you need to change a tire. There are many types of car jacks that can lift lighter or heavier cars. Your car should have an emergency car jack included.

Some car jacks are mechanical, and some are hydraulic. A hydraulic car jack is often easier to use but heavier, and most people store them in the garage, not their car. 

Using a car jack is essential if you have a flat tire and need to put on a spare tire. Always be very careful (see article) when using a jack since the car could potentially fall if the jack is not secure. You’ll need a leg nut wrench (usually included), the jack, and the handle. Place the jack on secure flat ground and jack it up the car.  

Keep a jack and spare tire in the car at all times to prevent long waits or being left alone and by yourself.   

11. Spare Tire

how-to-use-impact-drivers

The spare tire is an important part of driving a car. It provides peace of mind and the ability to drive your car until you get your flat tire fixed. This safety precautionary will help in case your car tire runs flat. Whether you do it yourself or have someone help you, changing your tires will help you get to where you need to go without having to wait for long periods. 

Later you can replace the damaged tire and put it back on. A spare tire should only be used temporarily and replaced with the tire your car had previously. Whether it’s a smaller spare tire or a regular-sized tire, after the tire is replaced, reinstall it on the car. 

Spare tires that are not full-size may be capable of only 50 mph and shouldn’t be used on the freeway. They are meant to be used for very short periods. 

The spare tire can be put away so it can be used again later if needed. To make sure you are ready at any time for a flat tire, ensure the spare tire is pressurized to the correct PSI and inspect it every 6 months. 

12. Transmission

automatic-transmissions

The transmission is how the car changes gears. It allows a car to climb up steep hills and move quickly. Sometimes it is called the gearbox. The transmission helps to transfer the energy from the engine to the wheel axle, where energy is applied to the wheels of the car. 

Most cars have automatic transmissions, but some cars are manual transmissions. You can find cars for a lower price that have a manual transmission (stick shift), and many sports cars also use these.

The manual transmission is cost-efficient, but when compared to the modern automatic transmission, the automatic transmission may save money in fuel costs. Still, the manual transmission is cheaper and easier for mechanics to work on.

To keep the transmission working well, inspect the transmission fluid levels every month and its color about every 6 months. After about 30,000 miles of driving is a good time to change the transmission fluid, depending on the car. A sealed transmission will usually last quite a bit longer.

13. Shock Absorbers

AD

A shock absorber is a device used to dampen the bumps and rough spots in the road. There are various types, including pneumatic (gas-filled), magnetic, hydraulic (liquid filled), and some also add springs.

The shock absorber will absorb the vibrations caused while driving. When a car is in motion, you can feel the vibration from the tires throughout the car. A shock absorber can take that energy and smooth out the ride.

To make sure your ride stays comfortable for the passengers, different cars use different types of shocks. A sports car will absorb bumps differently than a luxury sedan. 

Maintaining your shock is a matter of noticing when they no longer work well. Damage could occur if your shocks don’t absorb a bump, making your car touch the ground or bottom out. 

14. Air Filter

AD

There are generally two types of air filters in your car. The first kind of air filter is for the engine of your car. The other air filter cleans the air coming into the cabin, so passengers have clean air.

The engine needs air for combustion, and it is drawn through the filter into the combustion chamber. Dirt and particles in the air could create problems if not filtered. In addition, a dirty filter blocks airflow. So changing the air filter when dirty will prevent damage and give better fuel economy.

The cabin air filter, usually found inside the car cabin, will prevent dirt and particles from coming outside. Some air filters are good at filtering dust and tiny particles if you have allergies.

15. Spark Plug

AD

A spark plug is used in the combustion chamber to ignite the gas/fuel. It is timed to work with the cylinder and goes as slow or as fast as the engine RPMs. The spark must be effective in order for combustion to occur correctly. A misfire, rough idling,  or knocking can occur when spark plugs are not working correctly.

To check your spark plugs, you’ll need to be aware of how your engine is running. Replacement might be needed if the symptoms mentioned are occurring. You can also pull out the plug(s) and look at their condition. If it is very dirty, it needs to be replaced. The life span of a spark can be from 10,000 miles to 100,000 miles depending on the type and engine factors.

16. Catalytic Converter

AD

The catalytic converter filters harmful gases (carbon monoxide, hydrocarbons, and oxides of nitrogen), so only water and carbon dioxide come out. This helps the environment.

The exhaust from the engine goes into the catalytic converter, gets filtered, then enters the muffler. The catalytic converter can last the life of the car, but it can also get clogged or damaged. Usually, you won’t need to worry about the catalytic converter, but if you suspect a problem, make sure to get it replaced if needed.

Always make sure to replace one if it is broken. Driving without it is illegal. It is an easily fixable part, although it may be quite expensive.

17. Muffler

AD

If you’ve ever been in a loud environment and put on your headphone, you may have noticed the sound is dampened quite a bit.

A similar process happens with the muffler. The very loud noises that come from the engine are canceled out and reduced by reflecting off the walls of several chambers in the muffler. The sound that is then left exits the muffler and is released. Mufflers are great at reducing sound, and the engine would produce very loud noises without them.

Make sure you have a legal muffler, so you don’t get pulled over. Some people want to use less restrictive mufflers to help modify their cars to pull in more oxygen and perform better. If you hear loud engine noises from your car, get your muffler checked. 

18. Tire Pressure Gauge

AD

This device is not a part of a car; rather, it can be used to measure tire pressure. Your tires need to be checked every month or more often if needed. Tires with the correct air pressure will cause less tire wear, get better gas mileage, have better shock absorption on the road, and give better handling.

The correct tire pressure is usually located on a sticker you’ll see if you open the driver’s side door. Even if the tires appear full, check them because each tire sits a bit differently. Try to get as close to the PSI (pounds per square inch) for each tire as possible without going over. 

19. Alternator

AD

The alternator helps power the electrical system of the car. After the batteries help start the engine, the alternator takes over by producing electrical power to charge the battery and help power the car’s electrical needs. As the engine runs, it helps move the belt that is connected to the alternator, so it can produce energy.

To ensure the alternator is working well, you can check the belt connected to it and ensure it is tight. Another way to ensure your alternator is doing its job is to check the wire connections to the alternator and the car battery. This will help you know if the connections are good.

The alternator needs to be replaced if it no longer charges the battery or stops working. If you use a multimeter, you can check the health (see video) of the alternator yourself.

20. Power Steering Fluid

engine-oils

Most cars have power steering. The power steering system helps pump power steering fluid to the hydraulic piston. The piston helps make turning the wheels easier. To ensure that everything is working correctly, you can check the power steering fluid level around every month and the color every 6 months.

While checking the power steering reservoir, notice if the fluid level is low. Fill to the correct level is needed. If you suspect a leak check the hoses in the power steering system and replace them if needed. 

If you notice the fluid color is fairly dark, it’s probably gone past the replacement date. It should be replaced according to the owner’s manual suggests.

Conclusion

These 20 items are helpful to be aware of when you are driving a car. They can help you maintain your car and understand what is happening if your car has issues.
