What causes the engine to overheat?
An overheated engine is very often caused by cooling system failure. The cooling system draws heat away from the engine — where the combustion chamber can reach 4,500 degrees Fahrenheit — and pushes it to the outside. If something is wrong with the cooling system, such as a leak, then your car can overheat.
