This is an interesting problem. My fan clutch only operates intermittantly. It seems that most of the time it doesn't engage when the air conditioning is turned on. Turning the air con off then waiting a bit seems to fix the problem. It also doesn't seem to engage at idle speeds. It only engages around 1300 RPM or so. I don't know if that's normal or not. When it does engage, it works perfectly. Is the clutch itself broken or is there something else at fault here?
When your aircon is switched on, an aux electric fan should be running in front of the radiator, this would explain why the visco fan doesnt kick in properly.Quote:

I forgot to mention that my temp guage goes past the 12:00 mark if I'm just idling with the air con on. If I let it sit too long it will go way past it. So maybe the aux elecetric fan isn't funtioning?Quote:

probably. I just changed mine months back...fuse keeps on blowing and sometimes fan isn't working...turned out to be my fan was on its way out... bought one from the yard for cheapQuote:
