Coolant leak '91 200 qt

[Wolff <wolff_b@ix.netcom.com>]

OK, I finally need to ask the list for info on a somewhat serious
problem. The '91 200 qt gave me the MFD temperature symbol. Luckily, I
was right near home. (Jeff, this must be the "Gods" noticing our
discussion about adding a pressure guage to the coolant system). The
leak is drip...4 seconds...drip near the fan thermo switch as near as I
can tell. It is not obvious to me how to get to the switch or remove the
radiator. I'm hoping the radiator can be removed without discharging the
A/C. I'm also hoping the water pump isn't where the leak is. I don't see
the radiator removal procedure in Bentley. Advice anyone?
Thanks,
Wolff

P.S. People ask why I have 3 Audis. I say, "They are fun to drive.", but
listers know that I need a backup vehicle. Went to start said backup
vehicle ('84 4k) and cough, sputter, instant 3000 rpm and quit. Turn key
to repeat. Hmmm...remembering list discussions, this sounds like a nasty
vacuum leak. Put brake booster hose back onto manifold and voila! Total
repair time about 15 seconds. (Okay, a little longer if you include
adding a hose clamp there later in the day.)
