2000 GMC Sierra 1500

  • 2000 GMC C1500

I have a 2000 GMC Sierra 1500, 4x4, 5.3L V8 with 127,000 miles. Recently I went through some high water with it, and since then it has had a loud squeaking noise coming from under the hood. I have replaced the idler pulley, tensioner pulley, a/c belt, and serpentine belt and the noise is still there. Any ideas on what it may be?

Do you
have the same problem?
