Re: Squealing fan belts, which one?
- The soap bar trick works, but it seems to penetrate, or glaze the
belt, and force you to replace it. It actually lubricates the belt,
and lets it slip without making the noise.
I have found a better way is to use a little water squirt bottle and
wet one belt at a time. As soon as you get water on the noisey belt,
it will instantly quiet down - only for a minute until it dries off,
but you can then re-tension it without leaving any residue that will
destroy the belt.

- Reminds me of another instance .. Chevy Lumina van, flat ribbed
belt. Voltage reading would nose dive to 0. Almost always when I
was idleing .. blip the throttle and you would hear a small 'chirp'
and the alternator would start working .. or take off from a stop and
it would come back .. or idle for more than 30 seconds or so then it
would drop, come back, drop ... but never a long squeal.
Had a real slow leak from the water pump that would drip on the belt
where I could not see it. When the engine was cold there was no
pressure so it didn't leak and alternator would work fine .. for
awhile. I'd open the hood and look and see nothing of note
(alternator kind of hidden from view on this vehicle). Alternator
tested good and belt/tension was fine. Happened to have the hood
open and noticed the alternator was NOT spinning for about 2 seconds
and then would spin. Shut the engine off and waited. Veeeeeery slow
non-continious quick-dribble water leak. Never reached the
pavement. Replaced the water pump and problem went away. Off and on
two days to sort out.
I'm assuming things like this happens to others :)
