Re: ENGINE MAKING SCREECHING NOISE PART II
 

The noise is coming from the belt that drives the AC. The question is
why. If you are lucky the answer is that the belt is worn, glazed, or
loose. If you are not lucky, the compressor or compressor clutch is
going bad. A low charge of refrigerant would not cause this but a too
high charge could - but that could only happen if someone had physically
added refrigerant - did you let someone service it recently?

You must realize that the belt can be bad without "looking" bad. Your
symptoms are pretty classic for a "bad belt". Either worn, glazed (most
likely) or loose. The fact that is makes the noise only briefly is also
classic bad belt symptoms. If you replace the belt, the one you remove
will most likely look perfectly good (to you) but the new one you replace
it with will magically no longer make the screeching noise. You could
prove this with a $4 can of Prestone belt dressing (spray) which would
also solve the problem, but only temporarily, probably only a week or two
before it starts screeching again. Besides, belt dressing is messy. $10~20
bux for a new belt and a wrench and only a little bit of effort will fix
it.

Bubba,
I agree with you. That was my first guess as well. If the new belt does
not fix the problem--you may need a new AC compressor. That could be
expensive so I hope the new belt solves the problem.
