Thanks to all the guys that helped out, I cleaned the radiators, they had a lot of junk in there.

I started the car with AC on, Both fans are running. AC off, both fan turn off.
Temp 198.

Then I went for a drive, It is hot outside and I drove max 25 miles an hour around the neighborhood.- AC on the temp went to 205.

Then I turned the AC off, and the temp went to 211!!!!

Stopped the car, let it run, AC off, the engine fan turned on, BOTH FANS UP FRONT ARE OFF, temp went to 217, no light on dash.

I turned it off and now I am worried. I always have the AC on, so the fans where always running, and it never went this high. With no fans, I bet it would overheat.

Whats going on? Are the fans supposed to turn on? At what temp? I guess the sensor may be out....where would that be?
