A radiator is a device that cools the coolant by allowing it to circulate through channels exposed to air. As the coolant flows through the radiator, the heat is dispersed before reentering the engine. A fan exists to help air through the radiator that is usually activated when the vehicle is on idle. The water pump pumps the coolant from the radiator through the engine and back.
