Hi, I just had the belts replaced on my 03 Neon as per a recommendation from Pep Boys. Nothing seemed wrong with the old ones, but I went ahead with the change. Everything seemed fine for the first couple days, but now when I start the car up, I hear a squeal for the first couple seconds and then it disappears. It only seems to happen from a cold start if the car has been off for a few hours. I called Pep Boys and they said the Neon had an auto-tensioner, so that wasn't the problem, but I couldn't get it in to them today. Anyone have any ideas? Does it just need to be tightened, or Wd-40'd? Will it go away once its worn in?
