Engine Which fan clutch ?

[AnthonyA1234]

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?

Sure sounds good, no not really, I would be suspect poorly made parts but I don't have have hands on soooo,
Does it overheat?
What part number/brand part?

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?

Ftw go electric, I've had the flexalite Black magic extreme fan on my daily driven 93lx for 19 years so far.
Oh by the way I live on the surface of the sun( nevada)

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

Wait, is it possible the clutch was standard rotation?
I would think they a directional

Get yourself a Hayden 2723. Thats a non SSP unit so it will be quieter. I was never a fan of switching to electric, doesnt cool as well unless you get the perfect setup. And then it taxes the vatt/alt.

When you're sitting in traffic, how fast is that clutch fan spinning?

Electric fans wired properly with a good alternator don't tax the batt/alt. There's a reason new vehicles use electric fans.

If you're in a cooler climate they may work fine but not here in Satan's backyard.

I tried the HD clutch when I lived in SW Oklahoma as the standard clutch wasn’t cutting it and the HD struggled to keep up with a 3 core brass radiator (the old Godan unit from AutoZone) and a good factory fan and shroud.

Moved to a Mark VIII and DCC controller and zero issues. Later on I installed a big two core aluminum radiator due to the brass unit failing and repairing it was more than the aluminum one. Runs just as cool today as it did then.
