Just an update:
Removing the belt stops the noise.  I guess this means it's the water
pump, the alternator, or the belt.  I put on a new belt just in case,
still didn't fix it.  It's not terribly loud, but definitely quite
noticeable.

To be clear, when I wrote "I got out a hose to isolate the noise", I
meant I used a hose with one end to my ear and the other in the
compartment to try to track down the noise.  I just did this again.
It's not giving me much.

With the belt off, I turned the water pump pulley by hand, and got a
slight creak.  Slight enough that I usually wouldn't have worried about
it.  Is this a good indication that it's the pump?  When I point my
"noise" hose at the pump, I don't really hear the squeal much.  Is there
a good way to rule out the pump?

Thanks again,
