Cooling System: Description and Operation

ENGINE COOLING SYSTEM




At operating temperature, an automotive engine produces excess heat. Heat is a by-product of all internal combustion engines. Modern engines operate at higher temperatures and therefore run more efficiently - less of the energy produced by burning fuel is turned into heat, and more of the energy is used to power the vehicle. However, they still produce excess heat.

The engine is equipped with a cooling system designed to remove much of the excess heat. When functioning properly, the cooling system maintains an optimum temperature for the engine.
