I’m constantly replacing fan clutches in my car they always start whining and being super loud after like 3 or 4 months and showing reduced engine and AC cooling at idle. I’ve tried heavy duty and standard duty both sucked for me although standard seemed to be quieter at first till it went bad.

Which should I be buying standard or heavy duty? I just want something that’s quiet and actually lasts.

I'd be concerned about why they are failing, most last for decades.

I thought that as well, what would cause that? It could very well be my water pump pulley /bearing cause I haven’t changed that is that the main culprit?

I tried both types. The HD one was crazy loud all the time. By loud I mean the fan was being driven all the time. Sounded like a UPS truck.

I'm currently using the standard replacement. I got it from LMR. No problems with it. Is it leaking? They usually have printed on the box which way it should be shelved (stored). The fluid can leak out past the seal if its stored face up. Did the box look oily and damp?

I have the stock clutch fan stuff on mine but I really like the clean and (reasonable ly) quieter electric fans.
