My '98 K1500 makes a squeaking sound when it is running and I believe it is
the belt or possibly a bearing in one of the items the belt goes to. Any
ideas on what it may be or if it is the belt itself, is there some sort of
belt dressing I can put on it to quiet it down? The sounds is like if you
would say squeakity, squeakity, squeakity over and over again out loud. Has
been making this noise for a while now, alt is new and water pump was
replaced around a year ago or so along with the belt. Can't recall if it
was making the sound back then or not but now that I am tuning the thing up,
I don't want any extra noises if I can help it. New plugs, wires, & dist
cap go on tomorrow. Would like to do tranny fluid & filter change in the
near future if I can find the Mobil 1 Dexron somewhere around here since it
is due (or overdue) for a change along with the xfer case & front & rear
Most likely the belt as bearings tend to make a constant noise
(wwwwwhhhhhiiiiinnnnneeeeeee) while belts are more like you described
(squeakity, squeakity). Regarding belt dressing and the consensus that they
are bad news for serp belts.............I've used STP belt dressing on
various serp belts without a problem. It actually says on the can "for V,
poly-v and serp belts." I'd give the belt a small blast and see if it
quiets up. If it does, you know it's the belt for sure. You could then
clean the pulleys with brake parts cleaner or denatured alcohol to remove
the belt dressing that may remain on the pulleys before installing the new
Doc, you are right, but he can also use a spray bottle and a small amount of
water to spray on the belt. If the noise quiets down only to reappear in a
minute or so, replace the belt. If the noise stays, even with the damp
belt, start looking for a bad bearing in one of the following: alternator,
idler pully (most likely it is this), and even check the power steering pump
Put the Gator on my Yuk, all was well, few months later it was slipping and
Tensioner got weak, do both at once so ya can close the hood for a while.
Tensioner's not that expensive.
80k miles on mine when it went.
