Well I was out a litle bit ago, when out of nowhere my temp is up at the beginning of the red. Then a minute later it dropped like a rock back between 180-210. From there I went straight home with the heater full blast and it pulled the same BS a second time. It was climbing fast, then about the time I was going to pull into a parking lot and call for a tow it drops like a rock again. What would cause this? I was thinking it was most likely a stuck thermostat but a friend of mine was saying it could be the head gasket.

have you had any cooling system work done recently? could be that it just wasnt bled properly. any water in your oil? or oil in your water? do a pressure test on the cooling system

It was the stat. I changed it out for an old one I had that was still working when I pulled it. Works fine now. Thanks for the reply

I'm having this same problem. Are you saying that you replaced a "new" t-stat with the old one that it was supposed to replace and it fixed the problem?

Yeah, the old one still worked when I took it out so I just threw it back in. Problem solved. I have a brand new one in the hatch that I picked up in case the same thing happens again. The "new" one was about 9 months old and just decided to **** itself.
