How a Car Cooling System Works How a Car Cooling System Works

The cooling system of a car has 6 main elements in it. These are the radiator, the engine, the radiation cap, the water pump, the fan and the hoses. People are most familiar with the radiator because it plays a fundamental role in the cooling down of a vehicle.

The Function of a Car’s Cooling System

Keep in mind that the engine of a car is equipped with a series of combustion chambers. Gasoline is mixed up with air in these chambers and the fusion between the two is then set on fire to allow the car to move. The temperature inside the combustion chambers can rise at a high temperature, so high that it can reach nearly 2000 degrees Fahrenheit.

The Water Passageways in the Engine

A car's engine is also equipped with a series of passageways from which water is allowed to flow to cool down the engine itself and prevent it from overheating. These passageways make sure that the water reaches the combustion chambers, but at the same time, they prevent the water from mixing with the gasoline and the air inside the engine.

Remember that the water used to cool down the engine of a car has some substances in it. These particular substances dissolve and when the water reaches the combustion chambers, they leave white stains behind. The white stains are very helpful because they cover the walls of the pipes from which the water flows and therefore they allow the car’s engine to lose its excess heat and cool down.

The Function of the Radiator

A radiator is usually rectangular or square in shape. It also has a number of tubes around it, which are made of copper and aluminum. Each tube is then equipped with many small metal fins. The radiator allows hot water to flow into it.

The water transfers its temperatures to the metal pipes and fins. They then transfer the temperature to the cold air that flows around them. As soon as the water reaches the bottom of the radiator, the unit would cool down.

The Function of the Hoses

There are 2 hoses connected between the engine and the radiator. One hose is linked to the radiator from the top and the other one from the bottom. The hose at the top puts the water into the radiator and the bottom hose takes the water back to the engine.

The Function of the Water Pump

A water pump is attached to the engine and its job is to take water out of the engine into the car’s radiator, and then when the water reaches the bottom of the radiator, there is no need of the water pump because the water drops freely through the bottom hose back to the engine.

The Function of the Radiator Fans

Radiator fans drive air into the radiator to cool the water when the car is stationary. Most fans are connected to the water pump and they run at a very high speed. When you intend to use your car in cold weather, you are recommended to let the engine reach its average temperature first.
