Can't figure out what this noise is, so i am seeing if anyone else had this noise before.
I am getting a noise from the front of my enigne. It almost sounds like my water pump is about to go out. But its not leaking anything and I had it tested at the shop i go to and they said it is still good. They scoped it and said that the noise is coming from the alternator. But when they put in two other new alternators they made the same noise. They couldn't figure out what was causing the alternator to make that noise. The only thing they could tell me is maybe with the tension of the belts on the waterpump is just enough to tweak it to make that noise.
Oh and when the engine builds up the rmps the noise gets louder.
Any ideas is very much appreciated.
