Why does it continue to over heat even after changingth cylinder head gaskets?

Answers :

Overheating can be caused by a few different things such as the fans not going on, the thermostat being stuck closed, or blockages in the engine due to deposits (which can be resolved by flushing the cooling system).

Temperature gauge is rising to 3/4 level, but never goes above and does drop while driving, but continually goe

I have a 2001 Nissan Sentra and my heat is not working I have taken it to my mechanics and he can not figure out why it is not working he checked my head gasket and all heating coils, and even replaced the thermostat but it does not work.
