Overheating problem

I have a 1990 chevy celeberity with a 3.1 (6 cyl) engine. I have an over heating problem. The anti-freeze is circulating thru the radiator. I have replaced the temp. control sensor for the fan and also put in a new thermostat. This problems occurs at idle, or when stopped. I checked and the fan is running when ac is on. Fluid level is filled to proper level also, this is driving me crazy chasing this problem! Any suggestions?

The fan should also run after the thermostat has opened and the engine temp reaches 215-220 F or so. Leave the AC off, let engine warm up. If the guage goes up before the fan comes on, then there is a problem with the fan control.

Which temp sensor did you replace ? There should be one for the guage and one for the PCM, which is used to turn on the fan.
