That usta happen to me in my daily driver cavalier... What was really odd was, I'd pull to the side of the road and put it in park, and the temp seemed to drop... Sometimes I'd hafta to shut it down and restart it, and that seemed to (temporarily) fix the overheating...
I replaced the radiator, hoses, and t-stat...

I'm sorry, but I dont think you wanna know how my story ended

Describe what you mean by overheats....

The coolant temperature runs up to XXX degrees?
The rad boils over?

C4's run hot, what we think is normal, you may think is overheating....

Get a scantool and see wht the ECM is reading. That way you will get a better idea if it is the gauge or the real overheating that you are seeing.

The way this is written, it doesn't make sense. It takes time for things to heat up, and it takes time for them to cool off. Is there a time line, you've left out, or is it just a gauge problem?

RACE ON!!!
