I have a 2001 pt cruiser, it overheats even after checking boiling point, it is not the head or gaskets, what do you think it is? we changed the head gaskets and also checked the head to see if it is cracked, and it is not.
Vehicles can overheat for a few different reasons. It*s possible that your fan is not working properly or not coming on at all. If your coolant level is up to the correct level, you could have a blockage somewhere in the system that is not allowing the coolant to circulate. The easiest way to check this is to check temperatures of the system at various points. Part of the system would get extremely hot and other parts would stay cool. It*s also possible you have an air bubble in the system and it just needs to be *burped*. Be very careful if you are doing the work yourself. Coolant and parts of the engine can get extremely hot and cause severe burns.
