I did an AC recharge and threw out my overdrive band in my trans. Not related I suppose but I now look at it as a 'superstition' such as, if you wash your car, it will break down on you. :lol:
Not sure if it was mention, but check your radiator cap.
Had the same issues, checked everything. Even had a EX-mechanic look at it to tell me it was the head gasket. Thermostat fine, hoses good, oil full/clean. Bad cap.
Car ran hot at intersection. Wasn't able to use A/C.. put to much strain on things and heated faster, especially since my AC Condenser fan is out.
After replace the cap, I cant even force my car to over heat. not even more than 30%, running in 103 degree weather. (longest waiting intersection, ac on with bad condenser still) [[also noticed this car seems to bipass the ac condenser fan if it's not working properly and engage the radiator fan]]
