Hey guys! Just joined. I have a 2002
Grand Prix SE with the 3.1v6.
I've had a slight overheating problem for awhile now. First of all, my gauge is not correct it says it's running cold (about a 1/4" from 210 mark") even though it's warmed up, when I hook up my scan tool to it and go to live data, it says it's running at 210 or so.
The main problem is that when I'm at idle for 5-10 minutes, the gauge will slowly start to climb, the gauge says 210 but my live data will usually be around 220-226 degrees. I don't hear the fan running when it's gets that hot UNLESS I turn the A/C on. So when I turn the A/c on, I can hear the fan running at high speed, and it will go down my car to normal temperature, if I have time, I'll take pictures of it later.
That's all I can think of right now. Any help will be appreciated and ask if you need more detail in a certain part.
Thanks!!
