I took my belt off the other day, to replace with an older belt after I cleaned it ( b/c it was squealing), I noticed the shaft to my power steering pump I could move it in and out. After cleaning the belt and putting it on, and gave it time to dry, it didn't sequel at all. that was about 2 weeks ago, the squealing is back.
Try a NEW belt and make sure your pulleys are clean. If someone put belt dressing on it or pulleys are oily it will squeak. Another trick is to put a couple dabs of rtv on the belt on the grooved side (might want to shut the engine off first) I think GM had a bulletin on the rtv trick
Also try running a flat file across the pulley grooves....high mileage pulleys get sharp and not let the belt "seat fully" into the grooves.....sounds silly but if you look at an old pulley than one on a newer vehicle you will notice a difference.
And the more I type or read the word pulley it looks like its spelled wrong.
POOLIE MAYBE. i SEE SOME SPELLING ON HERE THAT i CANT EVEN FIGURE OUT WHAT THEY'RE TALKING ABOUT. It's almost as irritating as leaving the caps lock on (oops) Pulley is correct
LMAO, well I have two belts in the tool box, I took the old Napa belt off, cleaned the motorcraft belt and cleaned the pulley and especially around the powersteering pump, put it on, and the squel went away. I picked up some lucas power steering stop leak see if that helps.
