LOUD squeak coming from serpentine belt?

We changed the alternator and had to loosen the belt (1).When we replaced everything and tightened the belt it became very loud. Like power steering pump squeak. Hard to tell where it is coming from.The squeak wasn't there before.Is belt too tight or too loose? (95 Jeep Cherokee SE 4.0)

Your belt may be loose, or you may have a bed bering in one of your pulley's. I would start by getting the belt tightened. If that does not work you can easily find out where the noise is coming from......



1. Take a long screwdriver and CAREFULLY place it on everything that has a pulley. (Alternator, tensioner, etc.)



2. Place your ear on the end of the screwdriver. The screwdriver will magnify any noise that is going on inside that may be causing the problem.



You can also buy belt compound that will %26quot;moisten%26quot; your belt. Some really old school guys use a bar of soap on the belt to lubricate it. I would not reccoment that though. Very dangerous.



Hope you get it fixed....

Do that with a screwdriver and you could get it shoved in your head.

Squealing belt = loose belt

= pulley not turning for whatever reason
On v-belt in the past I touched a bar of soap to the edges and they stopped squealing. I would try tighitening the belt first.
