Hello Customer (name blocked for privacy), Thank you for allowing JustAnswer to answer your car question. Sorry for the delay, we have been very busy today.

I have a couple of questions for you please: Was the fan clutch the same type that was removed? (Thermal = coil on front or centrifugal = flat on front)

Does the fan make a roaring sound when your van starts to get hot?

Waiting on your Reply.

ACCEPTED

OK, well if you don't hear a roaring sound when it is getting hot, then it is not locking up to cool down your motor, so you need to get another one. (I have replaced clutches that have only lasted a couple of months)

It's cooling just enough to keep you motor cool without the A/C but when you turn your A/C on the excess heat generated by your A/C overwelms your fan capacity, thereby your overheating problem. Does that make sense?
