The combustion engine in cars generates a lot of heat. The cooling system is designed to keep your car cool and running at optimum temperature. The water pump pushes coolant from the radiator throughout the engine and transmission systems and back to the radiator. The hot coolant is cooled while travelling through the radiator, before being rerouted back through the engine. So the heat created by the engine is dissipated via the radiator.
