i had the AC on and i was in the BK drive thru, after a few minutes i noticed the air from the AC felt warmer, i immediately looked at my temp guage and it was 3/4 up toward H (hot). so i turned my car off and waited a min for my food, when i had to pull out i turned the car back on and drove off, the temp guage immediately went down, to further help i turned the AC off and put the heater on full blast, i drove home and it never went up again....so what could have caused this??? im about to take it for a spin and see if the guage moves up at all from where it normally sits. theres plenty off coolant, i even have water wetter in there from Redline, i adjusted the timing a month ago and i know its good cause the light went out in the ecu, radiator cap is good.....what do u guys think, thermostat....water pump....radiator?? ill definitely keep my eye on the temp guage everytime im in the car....im guessin if it doesnt go up for the rest of the day sooner or later it might, especially with the AC on.
