Clutch/Viscous Fans

[Jack_440 Savoy]

How can you tell if a viscous fan works properly ??? and What is the difference between a clutch fan and a viscous fan if any ???

There is no way to test a fluid drive unit, even the factory manual states to "replace with a known good unit if in doubt".

haha dont get me wrong, its good when oyu dont have space, but it makes alot of noise....from my perspective, and i think it probably creates way more drag on the engine than a clutch/viscous fan...
