Drive Belts Squeaking

Maybe you have a bearing going out on one of the pully's. Have you cleaned up the surface real good before butting the new belt on. Use alot of brake clean and wipe all the pully's and idlers real good. Be sure the replacement belts arnt longer than the original one. They sometimes get it wrong at the parts house. If your car has a tensioner it may be getting weak

First off, how many miles do you have on this engine?Since you changed the belt and still have the noise,you have one of your pulleys making this noise.Usually it's the ideler tensioner pully.Take the belts off.Turn the pulleys by hand including the alternator pulley.if you hear the slightest faint noise there's your problem.repalce the part or the pulley. A lot of times the alternator pulley does this,the front bearing or the rear bearing as well will make these nasty squeals.Find an auto electric shop that rebuilds alternators and have them replace the bearing for you,while your at it service your unit,it will save you in the long run.
