belts pullies and stuff

[Rusty Rae <rrae@cotl.com>]

Okay i have a few questions about my 4000 cs quattro bets abd pullies.
First off, the belt the is attached to either the water pump or the
power steering( the top gaget right in the middle) the pully has started
sqeeking slightly. Now I think that it is the pullies bearing, Now how
can I be sure, and if it is do I have to replace the whole unit, or can
I just replace the bearing? As I think about it further i believe that
it is the water pump, because it has 2 hoses coming out of it!
Thanks for your help
