93 S4 viscous fan coupling

[Fred Munro]

John;

The only reason for removing the viscous fan clutch is to replace it. It is
easier to unbolt the fan from the clutch - this gives enough access to
replace the T-belt.
FWIR the threads on the viscous clutch are standard. Mine was a bit rusty
and tight. You have to have a good pin wrench to secure the hub against the
torque required to free the bolt.

So I'm helping a friend do the T-belt on his '93 S4, and the viscous fan
coupling is resisting our efforts to dislodge it.  My V-fan coupling
experience is with BMWs and MBs, which use left hand threads to secure
the fan clutch to the hub.  Are Audis the same?  As always, all
knowledgeable replies are sincerely appreciated!  TIA, John
