How An Auto Engine Cooling System Works

If your vehicle is overheating it is important to know how an auto engine cooling system works before attempting to fix the problem. The engine cooling system has key parts that allow for the engine to remain cool while driving.  The key components are the radiator, hoses, cooling fans, and water pump. 

The auto engine cooling system starts with the radiator. The radiator holds the coolant that flows through the engine cooling system, allowing the engine to cool itself through conducting the heat of the engine into the coolant. The radiator is filled with a mixture of antifreeze and water. The proper mixture of antifreeze and water will depend on the time of year and the area in which you live.

Once the car is warmed to the correct operating temperature the thermostat opens up. The water pump then begins to  pump the coolants through the engine cooling system. The coolant leaves the radiator through the radiator hoses then passing through the engine block, the cylinder head, and in some cases the manifold drawing the heat from the components into the coolant. The coolant then flows back into the radiator where it is cooled by incoming are. The air can either be forced into the radiator from driving or from the cooling fan pulling in the outside air. 

The auto engine cooling system  is on of the most basic systems in your vehicle. The cooling system allows the vehicle to run at a cooler temperature, keeping the engine block and cylinder heads safe from cracking and warping under heat.
