S4 viscous fan coupling

[john at westcoastgarage.net]

You said, in reply to my plea:  "Yes, left hand threads. I use one of those 
belt wrenches from sears to hold
the pulley and whatever you can get on the 32mm(?) LH nut.
Good luck."

However, it's a conventional right hand thread.  I used a 20 hour Kroil 
soaking, a pin wrench (which has proven useful, from time to time, over the 
last 30 years), and substantial pressure in the CCW direction to remove it.

Thanks again to all who offered help!  John
