1992 Legacy L 2WD w/Squealing Belts

Most likely is the belt needs tighten more. A bearing in one of the
accessories could be failing or the harmonic baslancer has seperated.
Last two are fairly rare.
 
John's right - just do make sure you don't indiscriminately tighten the
belts too much as that can cause one or more pulley shafts to actually
bend (now ask me how I know :)

Once you've established that the tension is right and yet it still
squeels, you could use some belt dressing compound to spray on your
belt to see if it wants to stop (an in effect see if a bearing might be
bad).
I've had one car that just would not stop squeeling in winter months,
regardless of the tension and condition of the belt. One spritz when it
fist made noise did the trick for me for the year.

I have a friend who has been a mechanic for a long time. He says not to use
belt dressing. His solution is to use a little brake fluid. I have not tried
it so I personally don't know. I have a 91 Ford van with a 302 and I'm
having a problem with a squeeky serpentine belt even after replacing it and
the idler pulley/bearing. Just might get around to trying the brake fluid
method.

The one tensioner on the 2.2....the one on the left as you sit in the
car...is famous for failing. TG

What is going on? I have replaced the belts twice already.

Check the aircon idler pulley. I had to
regrease mine. Note that in this case, it's
the bearing that squeaked, not the belt.
 
That's the old school trick -- works as well. I have never heard belt
dressing was bad, though. Is that what he's saying?
They start making noise is when they get dry so it is more pronounced
in wintermonths.

Belt dressing seems to be a great way to get
normal belts to start squealing. I haven't heard
of brake fluid for it, but silicone lube spray
has worked great for me.
 
Even though belts are the correct length they may not have the proper
V angle. This is a common problem with after market belts when
one-size-fits-many. Several Suby owners have reported belt squeaking
problems and it was resolved by using an overpriced? OEM belt. Just a
thought is everything else checks out OK. Eddie

I'm pretty sure that's all that belt dressing is, though.


Not sure if you're responding to my post, since
you didn't quote---the belt dressing I picked up
a few years ago left a sticky, tacky residue.

Tried it on a noisy belt, and sprayed down the
one next to it, just for grins. Result, *two*
squealing belts!
