[QUOTE="Blkkbgt, post: 16474988, member: 117234"] Something isn't right here even with a stock temp range t stat you should not be having seeing temps that high. Are you sure you burped the system correctly? These engines have been know to hold air pockets and this is why I always recommend burping the system with the car on ramps or the incline of a driveway whenever possible. I have had a similar issue but not with the AC on and it turned out to be air in the system. Have you verified this ONLY happens with the AC on and that it wasn't just a coincidence? Those systems are completely separate and should not impact each other. Are you sure your new t stat works? Stupid question I know but I've actually had one fail shortly out of the box one time in my life. I'll probably never see it again but its worth checking. Are you sure your fan is running and kicking on at the correct time and temperature point? This is a big one because if you needed your AC then your fan should have been running as well. Usually the answers to cooling problems is simplistic. [/QUOTE]
