Have your antifreeze fluid changed and Cooling System flushed every 30,000 miles or 2 years. Newer formulas, however, may last up to 50,000 miles. To check coolant level, turn the car off and wait for the engine to cool. Locate the coolant reservoir (usually a translucent plastic tank) and eyeball the level of the coolant against the full and low indicators.
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 condition to ensure that the whole system works efficiently.
