I replaced the water pump and thermostat, cleaned the radiator and the engine started overheating. Turned out that the fan's 1st speed resistor died and the second fan didn't turn until the computer gave the command for the 2nd speed. My mechanic's solution was rather neat - he short-curcuited 2nd speed. This made my case even worse. Turned out that the fan itself rusted and didn't turn at all. The short-curcuit almost caused a fire!!! Now all is well - I have a new fan block installed.

Also 1 or 2 rad fans? What's the temp gauge doing w/o a/c on and will the rad fan(s) come on if you just sit at idle, in park, for a while with a/c off? I've got a '95 GL V-6 with 5-speed manual tranny... built on 9/7/95... I think all V-6's have 2 fans if I'm not mistaken. The fan(s) do come on at idle with the a/c off, when it's hot outside... like it should.

No mist/fog though.... I'm having the a/c checked at my local dealership...

The fan's bearings were made too tight or something if I recall correctly..... Did your "overheating" occur correlate to the a/c being on?? Thanks

This is something that occurred while my car was under warrantee, but the dealer found nothing wrong. For those wondering, I have the V6 and it definitely runs hotter with the AC on. Should i look to the fan first and if it is a blower problem, was that something that should have been recalled?
