Actually, a dealer in Rockford did that and it lasted for about 50 miles. When I got back to Dayton, the belt was really screaming. It also flung belt dressing all over the other pulleys. The alternator even had dressing on it. Grrrr!
Everyone has always told me that the pulleys have to be shiny clean or you can experience chirp.
Nevertheless, you are on the right track Moot. I could take a small piece of cloth, put about two drops of NXT Tech Protect on it and then hold it against the top or bottom of the belt while the engine was running. The squeak would disappear for about 2,000 miles.
Today made my fourth attempt to resolve this problem. I thought it might be floating up and down, because it would get louder when the tranny would shift into high and the engine speed was changing. Hmmm. Then I began to think it might be walking on a pulley in a front to rear manner. I simply asked if they could have their best technician look at the alignment of all pulleys. He has 30 years of experience.
Seems the power steering pulley was 1/16th out to far. The belt showed a little wear on one edge. Pulley was aligned and the belt was replaced. No squeak so far!
Later on I was talking with a driver on the phone and he said that GM had a TSB about checking that pulley alignment. His never squeaked, but he remembered them checking it once.
Thanks for your help! I’ll keep you updated if there are any changes further down the road.
