My Buick Roadmaster with the 350 V8 has 2 grooved belts, one serpentine and another that runs the power steering pump....both have spring-loaded idler pulleys. .......the belts look fine but still have some squealing especially in the mornings....I've sprayed both belts with Prestone Belt Dressing and have tried some silicone anti-squeal, but they still squeal some. I'm considering just cleaning both belts with Purple Power or Carb Cleaner to strip off all products and start with clean belts....Or....have new belts installed. But like I said, they both look fine. Any ideas on the best course of action to stop this squealing?.....I used to use a bar of soap on the old V-belts but these are multi-V design....
