Could be... or could be the pulley scraping against the pump housing.
Easy to check... remove belt and run engine -- if sound goes away it is
either the water pump or the generator. You can make a 'belt' from a
length of 1/8" nylon rope around the crank pulley and water pump pulley
to see whether it is the gen or pump. The rope doesn't have to be
terribly tight and a knot won't matter though you may have to push it in
on one side with a stick to get enough tension to get it to spin the
pump... then you'll listen for the chirp to return. Fresh in my mind
because I did all this recently to confirm my pump was bad.
Rebuild is certainly possible but parts may be a problem. IMO easier to
add a dummy zerk to a good replacement pump.
