I noticed my radiator over flowing with heat today
well i chequed everythign and it was ok while the car was running and i bumped into the clutch fan and it stopped spinining
i was like that should have at least hurt
whats going on
i looked deeper to realize that the clutch fan spins seperately from the eccentric shaft as if it isnt connected
i know it should spin faster

anyone have an idea as to how i should connect the two
i pulled on the fan
they seem connected but im probably doing something wrong

 

The clutch has gone bad. If you touched it while it was running, you would lose your finger. Im not sure if you can repair it, I've only heard of getting a replacement clutch.

 

Once its gone its gone. Go to a junk yard and look for a good one, as the new ones are horribly expensive, IIRC.

 

but the clutch works
the fan spins seperately of the eccentric shaft??
i thought it was suppposed to spin at the same rate??

 

anyone?

 

A few years ago I had a bad fan clutch, so I did some exploratory surgery on it:
The fan clutch uses a silicon oil viscous fluid in two chambers inside.
A Bi-metal strip on the front bends outward as it warms and opens the valve from the reservoir side to the clutch side.
Centripetal force provides the pumping action to move the fluid.
When it sits for a few hours, it will spin the fan briefly on startup, then freewheel.
After 100,000 miles the bearing seals inside wear, and the bearing lube starts to weaken the clutch fluid's grip.
Both the S4 & S5 clutch freewheel when cold.
The s4 clutch increases it's bite gradually with temperature rise.
The s5 clutch is more on-off. (It just coasts until is gets warm)
Once they are warm, the fan speed goes up with engine speed to about 4000 RPM.
As the engine revs higher the fan stays at ~4K.
If your warmed up fan only revs up to < 2500 RPM, it's worn out.

 

My fan busted in the opposite, actually siezed up, spun all the time @ all temps... Most of the time when they get old I think they just stop spinnin...

 

Have you got an S4 or S5?

 

go with an electric fan?

 

i have an s4
and my s5 dosnt fit

im looking now for a escort fan to put on

 

escort fan works grea and it was a fun install
