Everytime when I turn on the a/c in my civic and leave it running for more than 5 minutes during idle, I see the temperature needle going up. Why is this happening? I already check the coolant, both fans are running fine, and I also got a new thermostat. I have never had this problem with my car until about 2 weeks ago when it happen. By any chance, do u think that the timing belt could affect the overheating? The reason why I brought this up is because ever since its was changed, the belt has been making this low whining sound randomly and I think its stressing out the engine. Any explanation?
