It doesn't work? About the only thing
that works for serpentine belts other then
replacing them and the tensioner.....is to
spray them with something like brake cleen,
something that will "remove" any oil or liquid
on the belt.....and clean all the pulleys that the
belt runs in.....getting any and all oil/liquid that
might be built up in the grooves....and then you
might even have to run a wire brush up against
the belt (into the grooved side) in order to
rough up the belt a bit.
As soon as something like belt dressing is
sprayed on serp belt....you might just as
well forget about it not squealing. It may
be quiet for a few minutes...even a few hours,
but it never fixes the problem.
