Define "overheats". Does the gauge peg in the red with coolant boiling out all over the place, or does the gauge just run a little hotter than the middle? Does this happen at all speeds, only on the highway, only idling in traffic...?

Overheats as in the temp guage goes all the way up then my cluster starts buzzing at me. Then i turn the ac off and the temp starts to drop to normal within a matter of 10 minutes. And this is while driving city, freeway and idle.
