Just like human beings, the car needs to dissipate heat in order to avoid overheating and exhaustion. During combustion, the engine produces large amount of heat—about 4,000 degrees Fahrenheit. This is too much for the engine to bear so a cooling system is needed to keep it at a normal temperature. Cars usually overheat due to a damaged part in the cooling system, especially the radiator, the heart of the cooling system. It is therefore necessary that all its auto parts must be in proper working.
