How to Test an Alternator: The Basics You Have to Know

Written by Chris in Auto Parts

How to Test an Alternator

As a car owner, you have the responsibility to make sure that all components are running in their peak condition. Among the parts, one of the most important is the alternator. The alternator is important for the production of electricity and providing the power that is needed by the engine. It may be lightweight and small, but it is definitely an integral part of the car’s hood.

In most cases, testing the alternator can be done on your own and without the need to look for a trained mechanic. Here are a few steps that you have to follow to test an alternator:

  • Turn off the engine of your car.
  • Get your multimeter ready.
  • Connect the red clamp to the positive and the black to the negative terminal.
  • Start the engine of the car and notice how the display in the multimeter changes. 
  • The value should be anywhere from 14.2 to 14.7 volts.
  • If the number is higher or lower, this is an indication that the alternator has a problem.

In the rest of this post, you will learn how to test an alternator to figure out if there is any problem. You will know the basics of a problematic alternator. From the first sign of a problem, you need to act immediately to prevent the issue from worsening.

Things You Will Need to Follow this Tutorial

Before you start testing an alternator, there is one important thing that you need to have:

  • Multimeter

Step-by-Step Guide on How to Test an Alternator

In this section, we will have a discussion of some of the most common testing methods that can be done to see if there is a problem with an alternator and to prevent it from being worse.

Use a Multimeter

A multimeter is one of the most important tools that every car owner needs to have. It is a multipurpose tool that can be used in measuring three electrical characteristics – resistance, current, and voltage. To test an alternator, the device needs to check the voltage, which can be done by following the easy steps mentioned below:

  • Turn off the engine of your car and open the hood. Give it a few minutes to cool down before you start working.
  • Get your multimeter ready. Select the DC volts and set them to 20V.
  • Before connecting the clamps of the multimeter to the battery, make sure that the terminals are clean. Otherwise, you might end up with readings that are inaccurate. Connect the red to the positive and black to the negative terminal. At this point, the display should show 12.6 volts or anywhere near that value.
  • Start the engine of the car and notice how the display in the multimeter changes. The value should be anywhere from 14.2 to 14.7 volts. If the number is higher or lower, this is one of the first indications that the alternator has a problem.
  • If everything seems normal, add stress to the alternator by running other components to have it adequately tested. Turn on the AC, headlights, and radio. If the voltage is lower than 13 or higher than 15, this is also an indication that you have a faulty alternator.

To have a better understanding of the things that have been mentioned above, watch the short video below:

Testing without a Multimeter

Even if you do not have a multimeter, you can still check the alternator for problems. In most cases, you just have to perform a physical inspection. Here are some of the things that can be done:

  • Check the condition of the drive belt. It can become loose, or there can be missing chunks. If it is already in bad condition, this can cause charging problems in the alternator.
  • The sound of the engine should also provide you with an immediate warning if the alternator is damaged. If it produces a loud clinking noise or an annoying sound, the alternator can be the problem.
  • Observe the brightness of your car’s headlight. When the engine is off, turn on the headlights. Start the engine after a while. The brightness should fade for a while, but everything should be back to normal after some time. This should be a sign that the alternator is charging.

Pro Tips

To make sure that your alternator will not be prone to problems in the first place, keep in mind the tips that will be briefly mentioned below:

  • If you have an air-cooled alternator, inspect the condition of the external fan and see to it that there are no obstructions on the vents.
  • On the other hand, for an alternator that is liquid or air-cooled, check the recommendations of the manufacturer regarding the periodic replacement of the fluids and see to it that such will be religiously followed to avoid serious problems.
  • You should also focus on lessening the vibrations produced by your car, as this can contribute to damage to the alternator. Check the mounting bushings and see that they are installed properly. The mounting hardware should be secured in its place. If not, this can cause vibrations that could speed up the wear of your alternator.
  • Contamination can also cause serious alternator problems. Organic gunk and dirt, among others, can cause damage. If your electrical connections are dirty, this could also add stress to the alternator.
  • When cleaning the alternator, it is important that you know how to do it the right way. Avoid using petroleum-based degreasers, pressure washers, and spray cleaning agents.

As shown in the discussion earlier, the problem between an alternator and a battery can be hard to figure out. To easily pinpoint the cause of the problem, these are some of the important things to keep in mind:

  • If the battery is the problem, the lights will not open at all. On the other hand, if the problem is with the alternator, it will open for a while and start dimming.
  • For cars with an AM radio, the latter can also be useful in figuring out the problem. Turn it on and choose a low number without music. Start and rev your engine. The alternator is failing if you notice a fuzzy sound as you step on the gas.
  • Try jumpstarting the battery. If it works, obviously, this shows that the defect is in the battery and not with your alternator.
  • For those who are living in a place that is extremely cold, the battery is the more common cause of the problem as it usually won’t start. Checking the battery gauge on your dashboard is an easy way to verify the source of the problem.

Conclusion

To spot any problem early on and prevent it from escalating, you need to know how to test an alternator. As shown in the discussions above, the best thing to do is to use a multimeter if you have one. Otherwise, a quick physical inspection will be best. These tests can all be done on your own and without professional intervention.

How to Replace a Blower Motor Resistor: A Short Guide for Beginners

Written by Chris in Cars

Replace a Blower Motor Resistor

The blower motor resistor is an important component of the heating and cooling system of your car. As you turn on the heater or the AC, the fan starts, and air will start to get out of the vents. This fan will run because of the blower motor resistor. Therefore, when the latter is damaged, expect that you will experience discomfort in your car.

Here are the simple steps that you have to follow to easily replace a blower motor resistor:

  1. Locate the Blower Motor Resistor
  2. Take out the Blower Motor Resistor
  3. Disconnect the Wires
  4. Install the New Blower Resistor
  5. Wire the Pigtail

It is inevitable that this part will experience a serious problem and will ask for a replacement. If you do not know how to do this, keep on reading the rest of this post, and we will let you know how to replace a blower motor resistor. You will realize that it is actually an easy task that can be accomplished even without being a trained mechanic.

Things You Will Need to Follow this Tutorial

First, gather the tools and materials that will be needed for the replacement of the blower motor resistor, which will include the following:

  • Ratchet
  • New blower motor resistor

1. Locate the Blower Motor Resistor

Obviously, the first thing that you have to do is to determine the location of the blower motor resistor so that you know which component will be removed. It is located right next to the blower motor. The latter, on the other hand, can be commonly found underneath the dash on the passenger side or in the engine compartment.

2. Take out the Blower Motor Resistor

Now that you know the location of the blower motor resistor, remove it. You will need to first remove the components around the blower motor resistor, which include the pigtail connected to the AC and the blower motor cooling duct. At this point, you can now have easy access to the blower motor resistor.

Now, all that you have to do is to unscrew the bolts that secure the blower motor resistor in place. Use a ratchet with a short extension. Once the bolts are out, all that you have to do is to pull the blower motor resistor.

3. Disconnect the Wires

After pulling the blower motor resistor, you have to cut off the wires that are connected to the component. Cut the wires using the stripper or scissors that are made specifically to cut through wires.

4. Install the New Blower Resistor

Before you proceed with the installation, apply dielectric grease to the housing of the blower motor resistor. This will prevent water from getting inside, which is a common problem when you are off-road driving. Apply coating around the plastic, which will provide a sort of sealing to protect the component.

Place the blower motor resistor in the exact same place where it was removed earlier. Use new screws to have it secured in its position. Connect the pigtail, and at this point, you are done with the job. However, there are also some instances wherein the pigtail has already worn out. If this is the case, proceed to the next step.

5. Wire the Pigtail

Cut down the old wires and connect the new ones. This should be easy, as the wires are probably color-coded. Use the connectors to connect the new wires. Put the pigtail in its original position, and at this point, you are already done with the task.

To make the steps mentioned above clearer, refer to the short video that is shown below:

https://www.youtube.com/watch?v=Q-i0tytSYIM&index=104&list=PLDD611CFB36FC65F2

Pro Tips

Aside from knowing the steps that are involved, you also need to keep in mind the tips that will be briefly mentioned in this section.

Knowing If It is Bad

How would you know if the blower motor resistor is asking for a replacement? This is not one thing that can be answered with simple guesswork. There are signs and symptoms that you should watch out for, including the following:

  • One of the most common signs of failure would be when the blower motor is stuck on a single speed. Because of this, the heater or the fan in the car will only function in a single setting, and you will notice that the temperature does not change regardless of the adjustments that you make.
  • There is also a problem if the blower motor does not work in specific settings. This can be frustrating as you might be stuck in the same setting.
  • If there is no air coming out from the vent, this can also be one of the indications that the blower motor resistor has already failed. If the blower is turned on but does not generate any air, check the blower motor resistor.
  • Another easy way to tell the problem with a blower motor resistor would be by performing a quick visual inspection. If there are signs of wear, such as corrosion and rust, it would mean that you will need to replace it.

Tips for Replacing a Blower Motor Resistor

  • You need to remove the components from the blower so that you can easily access the blower motor resistor. This will give you a clear sight of what needs to be removed.
  • The steps mentioned above will be applicable to the removal of the blower motor resistor that can be seen in the engine compartment. If it is in the passenger seat, you will need to remove the glovebox first so that you can remove the component.
  • You might also want to test the resistor first with the use of a multimeter. By doing this, you can be sure that there is indeed a problem with such a part and that it requires a replacement.
  • The steps mentioned above have also noted crimping the pigtail as a necessary step when the wires are already worn. In some instances, the task might also require the need for shrink-wrapping and soldering. They might require more effort, but it will be good in terms of making sure that they will no longer be as easily prone to wear and tear.

Conclusion

From the steps and tips mentioned above on how to replace a blower motor resistor, it is apparent that the task is pretty much straightforward. You will need basic tools to complete the task. There is no need for extensive technical knowledge or a lot of time and effort to spare. You do not have to call a trained mechanic to do the removal and replacement for you.

Best Coilover Kits: An Essential for Improving your Vehicle’s Suspension

Written by Chris in Cars,Reviews

Best Coilover Kits

If you are thinking of upgrading the suspension of your vehicle, without a doubt, a Coilover is one of the upgrades worth considering. It can be effective in changing the height of the vehicle and in the improvement of its handling. While it is beneficial in more ways than one, all the good things will be realized only if you end up choosing the right product.

To buy the best Coilover kits, here are some of the most important buying considerations:

  • Reviews: Positive online reviews
  • Price: Provides excellent value for money 
  • Inclusions: The kit should have everything needed to complete the installation.
  • Construction: It should be made of Aluminum or stainless steel
  • Compatibility: It should be compatible with your vehicle

While there is an abundance of options for the best Coilover kits, this should not give you an excuse to choose just any product and expect that it will deliver superior quality and functionality. You have to be a responsible buyer and take time to assess the possibilities, which is exactly why you need to read this guide before you make a purchase decision.

What is a Coilover?

When it comes to vehicle suspensions, you will have two main choices – spring and Coilover. In the rest of this post, the focus will be on Coilover. The latter is a shorthand for coil spring over the shock. A kit is inclusive of a shock absorber, which is encircled with a coil spring. They are already pre-assembled upon purchase.

In a Coilover, the spring is the one that is responsible for carrying all the weight. The shock absorber, on the other hand, has the main purpose of dampening any bouncing that could possibly be created by the spring.

Benefits of a Coilover

A lot of you might see Coilover as an unnecessary and expensive upgrade. Once you are familiar with the benefits, however, you might find it easier to be convinced that this can indeed prove to be an excellent investment.

  • Good Handling: This is perhaps the best thing that could summarize the advantage of having a Coilover suspension. Compared to other stock suspensions, this can deliver a better performance.
  • Adjustability: If you want your suspension to be customizable, you will have another good reason to choose a Coilover. This will allow you to enjoy a low ride for your vehicle and will provide you with complete freedom to adjust your suspension.
  • Specialized Setup: Some people do not really need to be provided with a concrete reason why they should install a crossover. They are only after the prestige, being able to tell their friends that they have performed a great upgrade in the suspension of their vehicle.

While it can indeed be beneficial, it is also important to point out that there are also some weaknesses. One of the most commonly cited drawbacks of a Coilover is its stiffness. There is also a possibility that it will fail. Nonetheless, these concerns will only be true if you opt for a product that comes with inferior quality. This makes it important to be a wise buyer and choose carefully.

Types of Coilover Kits

AD

Before you decide which one will be the best pick, you first have to be familiar with the types that are available and how they are different from one another. When you are aware of the mechanism by which they work, you can easily reach a well-informed decision:

  • Coilover Sleeves: Of the four types that will be mentioned, this is the one that comes with the lowest price. Their height can be adjusted. It is almost similar to the way lowering springs work.
  • Non-Shock Adjustable Coilovers: This also comes at an affordable price, although not as cheap as the one identified above. Its height can also be adjusted, but you won’t be able to customize its stiffness and compression, as well as the shock rebound. Most of those that fall under this type already come pre-assembled.
  • Shock Adjustable Coilovers: This is quite the same as the non-shock adjustable Coilover, with the main difference being the fact that it comes with a better shock.
  • Shock Adjustable Coilovers with Camber Kit: For a balanced suspension upgrade, this is the best type that you have to take into consideration. The height and the shocks are adjustable. It is also inclusive of a camber kit, making it able to provide value for money.

How to Choose the Best Coilover Kits?

To create a shortlist of choices and decide which one can provide the best value for money, here are some of the most important buying considerations:

  • Reviews: There is perhaps no better way to get started with your search than through reading reviews of other people. Through the feedback and real-life experiences that they are sharing, you will be able to learn a thing or two and make the right decision.
  • Price: The truth is, most of you will probably think of choosing a cheap product because it is easier on the wallet. Nonetheless, you have to proceed with caution as this could compromise performance. You should not hesitate to spend a little more if this means that you can enjoy a product with functionality that is hard to rival.
  • Inclusions: Because you are buying a kit, you have to take a look at what is included in the package. Some options can be cheaper compared to others, but this can be because they are incomplete. It would be better if the kit came with everything that would be needed to complete the installation.
  • Construction: This refers to the materials that are used in the Coilovers. Aluminum and stainless steel are two of the most popular, which are both great in terms of their durability. It will also be good if you will choose one that is zinc-plated, which is known for its ability to resist corrosion.
  • Compatibility: Take note that not all Coilover kits are created equal. Before you buy, you have to make sure that it is compatible with the vehicle where it will be placed. Otherwise, you will just end up wasting your money.
  • Outcome: Of course, you have to think of how the overall performance of your car will change after installing the Coilover. This will be easier to determine if you look at the technical specifications of the product and see what it can do to your suspension. The ride must be smooth, and the desired height must be achieved.
  • Warranty: Look for a Coilover that comes with long warranty coverage. Perhaps, choose one with a limited lifetime warranty for your peace of mind. Do not forget to read the terms and conditions of the warranty. In the case of some models, the warranty will not be honored if the installation is not completed by a professional.

How is Double Din Audio System Better Than Single Din?

Written by Chris in Cars

Double Din Or Single Din

Most of us spend a significant amount of money on buying a new car. However, in addition to the expense you incur on buying a new car, installing the right automotive stereo system is also pretty important. When you look at the type of stereo systems, two options which you will come across are:

  • Single Din Stereo System
  • Double Din Stereo System

DIN stands for the range of the stereo system. A double DIN stereo has a range of 180 mm x 100 mm. When you compare this with the single din stereo, you will realize that the double din stereo has a significantly higher. There are a few other benefits of the double din stereo such as The double din stereo systems come with a touchscreen, have mobile app support, are larger in size, have better integration, and have easy connectivity.

It is important to distinguish between double-din stereo and single-din stereo. Only once you distinguish will you be able to pick the right one. According to David Foster, just by looking at both options, you will not be able to easily distinguish the differences. Obviously, the double din stereo is much better as compared to the single din stereo. In order to understand the advantages of double din stereo, you have to look into the technicalities of both options.

1. Touchscreen Display

In most of the double din stereo systems, you will notice the presence of a touchscreen. This ensures that you are able to control the stereo system quite easily. You will be able to enable the various functions in a much easier way. Touchscreen input provides you with an excellent GUI to control the stereo system.

When you compare it with the single din stereo, it consists of a button panel that helps you control the stereo. The control panel of single din stereo is much less interactive. Only a few latest variants of the single din stereo systems consist of a touchscreen.

2. Mobile App Support

In most of the double din stereo systems which have a touchscreen, there is also support for mobile phone applications. This means that you will be able to directly play the songs from your iPhone or from your android smartphone. This eliminates the need for transferring the songs to a USB drive. You need not worry about the USB slot or any other connectivity mode, as you can easily control it with your smartphone.

Mobile app support
Via: https://www.pinterest.com/pin/803188914763653150/

The single din stereo system does not consist of any operating system apart from the ones which have a touchscreen. Thus, the capability to control it with the help of mobile apps is minimized to a few models. As for the models, which do not have a touchscreen, the control panel at the front provides you with the control interface.

3. Larger in Size

The large range of the double din stereo system can be attributed to its large size. When compared to a single-din stereo system, it is larger in size, which provides it with a better range.

At first look, a smaller stereo system might seem like an advantage, but it is the cost and lack of range of the stereo which nullifies the advantage.

4. Integration with Online Streaming Applications

In most cases, the double din stereo has the android operating system. With the help of this operating system, you will be able to install a wide variety of mobile applications. You can install entertainment streaming applications. With the help of these applications, the content which you will be able to access is unlimited. This opens up new avenues for you when it comes to automotive entertainment. Also, this ensures that you are able to use your normal entertainment app accounts in your automobile as well.

The support for mobile applications is pretty limited when it comes to single din stereo systems. Moreover, with limited range, it is not much of an advantage either.

5. Better Integration

Double din stereo allows you to connect your smartphone or SD cards to it. This means that there are virtually unlimited entertainment avenues that you can tap into. You can easily decide the source with the help of which you want to access.

Better integration
Via: https://twitter.com/joyingauto/status/847363776953303040

Single Din stereo systems are somewhat equal in this department as some models of single-din stereos can also provide you with such integration options.

6. Hands-free Calling Operation

Your smartphone can be easily connected to the double din stereo system. This ensures that you are able to use it for taking calls in a hands-free manner. This makes it easier for you to concentrate only on driving. In case you want to take a call, you need not pick up the smartphone. You can use the hands-free option of the double din stereo. This will allow you to communicate with the caller without taking your eyes off the road. Thus, in addition to entertainment, safety is also enhanced with the help of the double din stereo system.

The latest models of the single din stereo can be connected via Bluetooth to your smartphone, but the Achilles heel proves to be the range that again limits the call quality.

Most people just consider the advantages pertaining to entertainment. The truth is that, with the help of a double din stereo, you will be able to make your automotive stereo system much more versatile. You can even take a call which ensures that you are able to concentrate on driving at all points in time. In addition to that, you can access multiple entertainment sources, which provide you with a virtually unlimited number of entertainment options.

Best Starting Upgrade/Conversion: Our Top Recommendations

Written by Chris in Cars

Best Starting Conversion

If you have a car that is diesel-powered, keep on reading the rest of this post, and we will provide you with ideas on the best starting upgrade/conversion that you might want to consider. There are many parts of the engine that can be modified and replaced, each with the promise of making sure that it will help in the improvement of the overall performance.

You do not need to spend a fortune to have a car that performs better than your last. Many would think of getting the latest model, thinking that it has a higher-powered engine. However, you can enjoy improved performance sans the high cost through simple conversions and upgrades such as:

  1. Use glow plug override kits.
  2. Bore the cylinders in your car engine.
  3. Upgrade to a cold air intake.
  4. Upgrade to new diesel fuel injectors.
  5. Upgrade the exhaust system.
  6. Add fuel additives.

Read the rest of this post and learn more about some of the best things that you can do.

Glow Plug Relay

This is one that can prove to be best for old models of Mercedes cars. Through the years, you will notice that the glow plug and the glow plug relay will become problematic. Some of the signs that can be indicative of this include draining your battery and overheating the glow plugs, which can lead to more serious issues when they are not addressed immediately.

The old glow plug relays are no longer available these days. For this reason, you need to find a suitable upgrade or conversion. As shown in the video below, you can consider using Mercedes source glow plug override kits. It is not only more affordable but also easily accessible. Watch the clip below to learn more about how it works.

https://www.youtube.com/watch?v=OUhYuhvShos&list=PLtRKk64pu2wpQBZU9mSxKU2Wb-iSabXIT&index=5

Cylinder Liners

Dry and wet cylinders are among the main parts of a diesel engine. Wet cylinder liners exist in the form of removable liner sleeves that you can find on the cylinder block. On the other hand, dry cylinders are incorporated into the chamber. These cylinders are created for the purpose of making a tight seal so that compression won’t be able to escape.

One of the best upgrades and conversions that you can do in your engine is to bore the cylinders. In effect, there will be a greater area for compression as more fuel is burned. In turn, this will also provide the engine with more horsepower. This task, however, is not a simple DIY task. You will need to ask for a helping hand from experienced professionals to make the diameter of the cylinder bigger than it actually is.

Cold Air Intake

While cold air intakes have been around for quite some time now, there are still many people who are unable to see the benefits of using this as an upgrade to a diesel engine. The original air intake of your vehicle is not enough. In fact, it can restrict airflow, failing to provide the cooling that is required by your engine and all other components.

It is important to note the fact that for the diesel engine to run at its best, one of the main requirements would be plenty of air. This is exactly what can be provided by a cold air intake. It improves the amount of cold air from the outside that reaches the engine. It also improves filtration capabilities to be sure that impurities are kept out.

Diesel Fuel Injectors

Upgrading to a cold air intake is best done when it is complemented by having a new diesel fuel injector. They are designed to increase the amount of fuel that passes through the combustion chamber. It will result in a higher power output produced by the diesel engine. To add, it is also claimed that this can lead to up to a 20% reduction in fuel consumption.

When performing this upgrade, however, it is important to keep in mind that not all of the fuel injectors are the same. You need to find one that is suitable for the power requirements of the engine that you have. Using an injector with too much power can lead to the burning of the fuel, which can also speed up the wear of the engine.

Performance Exhaust Systems

The upgrading of the exhaust system will help in the reduction of engine heat. To add, it will also expel the gases that are produced by combustion. The original exhaust systems that you have in your car are designed basically to lessen the noise that is produced. Upgrading can be beneficial because it can improve performance, not just reduce noise.

Your original exhaust systems will have a narrow diameter compared to the aftermarket performance exhaust systems. To add, the latter is also straighter compared to the OEM. The difference in the design and the shape is the one that is responsible for the improvement of torque and horsepower by as much as 20 HP.

Fuel Additives

This is one of the simplest and cheapest of the upgrades that you might want to consider for a diesel engine. The good thing about this is that there is no need to replace or purchase any component. Instead, you will just mix the right additive in your fuel, and it can already bring significant performance benefits.

The additive has the main function of being able to improve the combustion rate of the fuel. With this, you will be able to have a smoother driving experience. It will also improve the horsepower of your vehicle, though the exact rate at how much it can do so will depend on the specific additive that you will be using.

Conclusion

Do you want a car that performs better? While many would say that the best thing to do is to buy a newer car equipped with a more powerful engine, this is not a financially-sound solution. Instead, the better thing to do is to consider the best starting upgrade/conversion suggestions that have been mentioned above.

As discussed, to improve the performance of your engine, some of the upgrades and conversions that you might want to consider include glow plug relays, cylinder liners, cold air intake, fuel injectors, performance exhaust systems, and diesel additives.

Change Rear Differential Fluid

All cars have differentials, although their location would depend on the type of vehicle that you are driving. They can either be in the front or back. For the differentials to maintain their peak performance, it is important that they are lubricated. For this reason, you will need to check the differential fluid from time to time and determine if a replacement is necessary.

 Here are some simple steps that you have to follow to change the rear differential fluid:

  1. Look for the position of the differential in your car.
  2. Drain the oil that the differential currently contains.
  3. Remove the cover, and clean it.
  4. Apply RTC surrounding the edges of the cover.
  5. Fill it with Fluid.

If you are interested to learn how to change the rear differential fluid, we get you covered in the rest of this guide. We will try to write it in the simplest manner that is possible so that you can easily understand the steps that are involved. Luckily, the task is pretty much easy and can be completed even if you are a car novice.

1. Look for the Differential

The first thing that you have to do is to look for the position of the differential in a car. It will be easier to do this if the vehicle is on a ramp so that you will be able to have easy access to what is underneath. If there is no ramp, a jack stand will suffice. See to it that the car is parked on an even surface for your safety.

2. Drain the Oil

Once you have located the differential, the next thing you have to do is to drain the oil that it currently contains. Use the ratchet or the screwdriver to have it open if there is an enclosure. A container should be placed underneath the differential to catch any fluid that will drip from it and allow enough time for the fluid to be completely drained. When you are done, do not just dispose of it anywhere. Proper disposal is necessary.

3. Clean the Differential

After draining the differential oil, remove the last screw or bolt from the cover and have it cleaned. Use a brake cleaner to remove dirt on the surface. Wipe it off with a clean cloth until it looks clean. After the cover, clean the surface of the differential using paper towels. Do not use anything that can scratch the surface, as it can cause leaks later on. As much as possible, use a plastic scraper.

4. Return the Cover

Once everything has been cleaned, it is now time to return the cover. Before doing so, apply RTC surrounding the edges of the cover. The thickness should be about a quarter of an inch. This step is necessary only if there is no gasket. Wait for 15 minutes to an hour before putting it back in the rear differential. Hand-tighten the screws and use torque to make them tighter.

5. Fill it with Fluid

After closing the differential, the next thing that you have to do is to fill it with fluid. Open the fill hole of the rear differential and insert a hose. The other end should be in your fluid. Pump the hose, and this will start the transfer of the fluid. Wait until liquid drops from the hole, which is an indication that it is now full. Put back the screw, and you are now done.

Pro Tips

After discussing the steps, this section will be focused on providing some tips about rear differential oil.

When to Replace Rear Differential Fluid?

In most cases, it is recommended that the rear differential fluid should be replaced after running for 30,000 to 60,000 miles. However, this can be dependent on a number of factors. To be sure, the best thing that you can do is to consult the manual and do exactly as it has been recommended by the manufacturer of your vehicle.

When it is time to replace the different oil, make sure that you do not mix different types. This is also the reason why you have to start by draining the old oil. Mixing two types can result in a problem and can compromise the performance of your car.

Choosing a Rear Differential Fluid

Now that you have decided that there is indeed a need to change the old differential fluid, your next concern is most probably which one is the best.

Among others, one factor that you have to consider is viscosity, which is recognized as the most important quality of any lubricant. Higher viscosity is generally better, which would also mean that the fluid is thicker. This means that the oil will be able to withstand even extremely hot temperatures.

If possible, look for a more expensive brand. This would mean spending more money, but generally speaking, this is also tantamount to having better quality.

It will be a good idea to read online reviews and ask experts in car repair and maintenance. They can provide you with valuable advice on which oil is best for your needs.

Other Tips to Keep in Mind

Aside from knowing when to replace and how to choose a rear differential oil, these are other important tips to keep in mind;

  • Be careful when draining and pumping gear oil. It can have a foul smell that will be reminiscent of rotten eggs. Wear protective clothing. If the differential is in the glove box, cover the floor to be sure that oil will not reach the surface.
  • Do not go beyond the recommendations of the manufacturer when it comes to when the rear differential fluid should be changed. Otherwise, it can create friction and heat, which will speed up the wear and tear of the different components.
  • The rear differential oil can also be hot. Allow the car to cool down before you work. Wear protective clothing and gloves. Also, have a container to catch the oil.

Conclusion

In sum, learning how to change rear differential fluid can be a huge money-saver since you no longer need to pay the pros to do the job. This is one routine maintenance that every car owner should learn. As shown in the discussions above, the task is pretty much easy and can be done without the need for expensive tools.
