[s-cars] Viscous fan clutch failure? - paging Dyno Dave Dawson!

[Peter Golledge]

Dave,
 
Got the clutch off with a "modified" oil filter wrench.  I drilled out the
rivet and put a longer link and put some rubber underneath the metal strap.
Removed the fan blade and Hydraulic pump pulley to get better access.
 
A new unit is on its way thanks to SJM. :-)
 
If that little plastic fan and clutch can sap a huge amount of power I'd be
surprised... its not driven on the V side of the belt so it would slip like
crazy with any serious drag on it.
 
I bought a new serpentine belt a few weeks back... guess the Car sensed it
and decided I better do it sooner rather than later. ;-)

Sorry, can't provide you with horsepower loss via the fan clutch.
 
I can say that if the fan spins that freely, it is probably shot.  As far as
A/C... if it doesn't work right after the car is started (from cold), the
clutch isn't the issue.
 
Removal varies.  The tough part is holding the pulley.  Some are on there so
tight that removal in the car is virtually impossible.
 
Dave
