My Aux Fan Makes My Car Hotter??????

[Massimo]

Is the Aux Fan connected to the airconditioning? I ask because i have an odd situation happening???

I had me radiator replaced and i don't think my mechanic turned on the heater when he filled the car back up with fluid. Well i know because my Cold/Hot dial is broken. So i bleed the system to the best of my abilities yesterday and hopefully this weekend ill be fixing the Cold/Hot dial. I am hoping the lack of water in the heater is what is causing this problem.

When i have the car running the temp guage sits perfect in the middle. but when i turn on the Aux Fan the temp gets up to 3/4. When i turn it off the temp gose back down but will fluctuate between 1/4 to 3/4 untill i bleed the system again.

So what the hell is going on i can't make any sence of it SOME ONE PLEASE HELP!!!

IIRC the "hot/cold" dial only moves a flap, and that there is not a valve in there.

With the AC on, your engine will get much hotter. The fan is suppose to cool the condenser more than the engine, but if your fan clutch is bad, when it is suppose to work with the higher temp, it might not.
