| | Why does a car engine overheat?Written by Jakob Jelling
There are many different reasons that can cause an engine overheat, but they all have in common three aspects. The three aspects which all engine overheat factors have in common are that they cause that heating system can not get rid of heat, they cause a loss of coolant or they directly cause too much heat in engine.One first problem which might be cause of an engine overheat is a problem with radiator cap and pressure it holds. If radiator cap does not hold pressure correctly then coolant could boil and therefore engine would overheat. Another reason might be caused by thermostat failures; it is recommendable that you check it. The car engine might also overheat due to coolant leaks such as those from radiator, hoses, water pump, freeze plugs or any others. Also, problems in water pump could be cause and therefore you should check it and replace it in case it is needed. Some other reasons by which car engine could overheat are problems in exhaust system which you can discover by checking vacuum readings, pipes and converter. Besides, you should also make sure that radiator hose has not collapsed and ignition timing is working properly.
