The wheel changed a lot and brought a revolution in the invention. Many modes of transportation were found for utilization in our daily lives. In the list of transport, the invention of the car brought a dramatic role in our day-to-day life.
The car has luxuriously changed a person’s life. Therefore, it is too hard to live such a life and lead a normal life. Although we have a car of our own, we must be aware of the parts of a car and how it functions.
Here, you are going to see the in-depth function of a car cooling system. After reading this post, you will feel as if you are an automobile engineer. The cooling acknowledgment about the car will also help you learn how to maintain it.
How Does a Car Cooling System Work?
The engine is the only thing that changes chemical energy to mechanical energy. In these contemporary days, the engine comes with gasoline. Thus, there is more improvement in the engine system.
However, these gasoline engines couldn’t turn out to be efficient engines. The seventy percent of the chemical energy turns into a heat energy than that of the mechanical energy. Hence, the cooling system takes the control to prevent the overheating in the engine system.
If there is an overheating in the engine system, it may lead to the engine’s halt. Therefore, the automobile engineers made a coolant system. There are two types and they are Liquid Cooling and Air Cooling.

The Liquid Cooling
In this cooling system, a cooled liquid circulates and moves through the passageways and pipes in the engine. The cooled liquid passes through the hot engine and absorbs the heat by cooling the engine at that instant. Once the fluid leaves the engine, it moves to the radiator and transfers heat.
The Air Cooling
The liquid cooling system and the air cooling system are alike, but instead of the liquid here, the air is used as a coolant. However, the air cooling system is seen only in a few modern cars and some old cars. The air cooling process involves with an aluminum fin that covers the engine.
The aluminum fin, while covering the engine, absorbs the heat from the engine and then transfers the heat to the air. The most number of car’s cooling system is the liquid cooling system. Thus, we are going to focus on the liquid system.
Let us take this little bit in a handyman’s way because the car engine has a lot of plumbing systems. The cooled fluid moves through the pump straight into the engine block. The engine block makes way for the fluid. This way allows the fluid to move around the engine cylinders.
The location of the thermostat is near the engine, the spot where the fluid leaves the engine. In case, the thermostat closes its opening then the fluid gets back to the pump. Suppose if that the thermostat is open, the fluid goes to the radiator and then back to the pumps.
There is another circuit to heat. The fluid from the cylinder head is carried by the circuit to the heater core and, after that, led to the back to the pumps. In the case of automatic transmission cars, a separate circuit for transmission is constructed within the radiator.
Then the transmission pumps the oil inside it and outlets the oil to the secondary heat exchanger within the radiator. Talking about cars, it has a variable temperature. It can be either below freezing point or above boiling point.
Hence, water is the most effective coolant for a car; hence, water is used in cars. Since the water freezes immediately, ethylene glycol is used to hike the cooling. Along with the freezing point of the fluid (water added ethylene glycol), the boiling point also gets a hike.
A unique or specified pump is utilized in cars. The work of the pump is to circulate the fluid in a car while the engine is turned on. The fluid flow process starts from the pump, then to the engine block, after reaching the engine block it moves to the cylinder head then to the radiator, and finally, it gets back to the pump.
There are many passageways for the engine block as well as the cylinder head. The engine has a combustion chamber, and the temperature in that chamber can touch 2500 degree Celsius. There is an interesting way to drop the temperature in the combustion chamber.
It is the method to reduce the amount of heat energy transferred. If we use ceramic layer, which a poor conductor of heat, then the heat transfer drops down. Here comes the heat exchanger or radiator.

The radiator in a car is a heat exchanger. The radiator is designed in such a way that it transfers all the heat from the hot coolant by a fan. The fan blows a speedy wind to transfer the heat from the coolant to the radiator.
The radiators have a tank on both sides. Inside the tank, you can find a transmission cooler. The transmission present in the radiator is like a radiator having another radiator inside. Here, instead of the coolant, the heat exchanger is between the oil.
The pressure cap hikes the boiling point of your coolant by 25 degrees Celsius. It acts just like a pressure cooker. A pressure cooker increases the temperature of the boiling water. The same process goes here.
After all these machines inside a car, the coolant’s work is determined by the thermostat. The foremost job of a thermostat is to permit the engine to heat up. After heating up the engine, the thermostat will constantly maintain the temperature of the engine.
Just like the thermostat, there is another friend to support in maintaining the temperature of the engine is the electric fan. Regular maintenance of your engine and cleaning the car engine safely will add life to your car as well as your engine. The best crate engines can prolong the car’s life.
