Purpose of cooling system in engine

In the engine during the process of converting thermal energy into mechanical energy, the high temperatures are produced in the cylinders of the engine as a result of the combustion process. A large portion of the heat from the gases is transferred to the cylinder head and walls, piston and valves. These parts are damaged and the engine will also be damaged unless heat is carried away so the adequate cooling must be required. 

A cooling system must be provided not only to prevent damage to the vital parts of the engine, but the temperature of these components must be maintained within certain limits in order to obtain maximum performance from the engine. Hence, a cooling system is needed to keep the engine from not getting so hot as to cause problems and yet to permit it to run hot enough to ensure maximum efficiency of the engine. 

The function of the cooling system :

The cooling system keeps the engine from getting not too hot but at the same time not to keep it too cool either.
