you should pressure test the cooling system, have been seeing issues with headgasket failures, possible radiator or fan issues, have it checked soon!

fan does not turn on. turn on A/C then pop hood and see if fans are moving. if they are, then leave car idle with A/C on and see if it overheats



blocked radiator

low fluid level

warped head
The electric fan should be coming on is it? It could also be the water pump itself but then you would get warm ....hot and then cool air for heat...warm for a while then it would be cool if it is doing that it is most likely the pump..if it is always hot it is probably the thermostst for the fan or just the fan itself. One way to test it is to wire direct to the fan and see if she spins...Hope this helps
