The radiator is a device for holding a large volume of water in close contact with a large volume of air so that heat will transfer from the water to the air. The radiator core is divided into two separate and intricate compartment water passes through one and air passes through the other. Air passes through the outside of the tubes between the fins, absorbing heat from the water in passing.                                                                                                                                    Figure Radiator of a cooling system of an engine.

Engine Cooling system: By the burning of air fuel mixture heat is produced in the engine. A small amount of heat escapes from the engine through the exhaust gases. If these heat is removed by using others metals or way it may make serious trouble in the engine. When the engine is running the water takes heat from the engine, becoming hot in the process.                                                 Figure: Open IC engine Cooling System   A water pump pumps the hot water from the engine water jackets into the radiator. The radiator has the two sets of passages. One set carries water. The other sets carries air. As the water passes through it gives up its heat to the air passing through. The cooled water then reenters the engine, where it can pick up more heat. In operation water continuously circulates between the engine and radiator, carrying heat from the engine to the radiator. By this ways excessive heat is removed.
