I also have a Zetec that can run hot often staying in the 'A'. I will be changing a few things soon...but my main concern is that sometimes when I start the car one of the fans is already on.... <P> My 98 SE was a Fleet car for a few yrs and the next owner was a guy in NYC who didnt do much upkeep.... any thoughts on why a fan would come on with startup? thanks ds

If your a/c is on, this will make the high speed fan run.

does anyone know the actual temp is when the zetec is overheating. my grand prix was 265°, along with my brother's old iroc-z. plus i do know that fuel injected engines run hotter than old carbed engines. so if the actual overheating isn't until 265° or so, then probly none of the zetecs are overheating. the guage may be calibrated to sorta say, "fool" us into thinking the car is overheating when it's really not.... i've had my grand prix overheat (cooling fan motor went out), and it made the interior all humid and fogged up the windows on a warm night while running.....
i know mine runs right up to the red in the city (used to be only when a/c was on), and only drops down to maybe the "A" on the highway. nothing seems to be wrong with it. it does have a misfire, dunno why. has new plugs/wires, maybe my coil is bad??? but no heat related issues....... oh yeah, and new water pump/timing belt 1 month ago, new thermostat (dunno temp, got it at autozone when i returned the "mondeo" haynes manual...) and oil change (mobile oil) yesterday..... still runs the same....

Just wanna make sure, the temp gauge sensor is on the bottom of the thermostat housing and the coolant temp. sensor is on top. I just replaced the thermostat to a 180. also had to replace the bottom hose with the metal tube, had a small leak in the metal.It was really rusty but i guess i would be rusty too if i had 225000 miles on me  . Thanks for any advice coming!

Update...I replaced the resistor yesterday. Now, the fan works, and it works at low speed. Hooray. On the bad side, the fan works when it should not be working.
When I turn on the ignition, after the car has been sitting all night, before I even start the engine, the low speed fan starts running. When I start the engine, the fan continues running. It runs all the time. Now, if I turn on the a/c, the low speed fan stops running, and after a few seconds the high speed fan kicks in, which I think is as it should be. The low speed fan stays off while the a/c is on, even when the a/c high speed fan cycles on and off.
If I turn the a/c off, I have no fan at all for about 35 seconds, and then the low speed fan starts running again. This is when the engine appears to be cool enough that the fan should not be running.
It also seems that if the car does get warm enough that the low speed fan should be turning on, it instead turns off. It's almost like the fan is on when it should be off, and off when it should be on.
Help?

i'm gonna reply to myself.... uhh... i guess when it's in the red, it means it's overheating. i was delivering in very hot weather (about 110°+ heat index) the day after i posted (go figure) and i kept smelling coolant, and i opened my hood before taking a delivery, and it was boiling over from every crevice it could find. hasn't happened since, i think it was just the real hot day.
