Squeaking in the Morning

. When I start the car in the morning I hear a loud squeaking noise. I took the car to the mechanic, he changed the serpentine belt. The noise came back a couple days later. I took it back he said the water pump was going bad. He changed the pump and yet and still the noise exists. He said that the leaking from the water might have warped the belt and changed the belt again. The noise has come again. It is a very loud bird like chirping/squeaking noise that speeds up with acceleration. The noise stops once the car has been driven for about an hour.

Is the tensionier good? Is there a glaze on the belt surface or pulleys?

The guy said the tensioner was good. But there is a bit of a glaze on the belt. There are also lines on it that I dont think I saw when the belt was new.

If the tensioner is good, then you will have to try to clean the pulleys. I always use brake cleaner because it will take all grease and dirt off and it evaporates within a minute. Remove the belt and spray it on one pulley at a time and wipe it clean.

I can't guarantee it will work (especially if the belt already has a glaze on it) but like I said, if the belt is tight, it should take care of the problem. However, remember it is flammable, so don't spray it on anything that is hot and avoid allowing it to enter the alternator.
DO NOT use a belt dressing, it will get in the pulley grooves and make things worse. A small wire brush will also help get the old rubber out of the bottom of the pulley grooves

Let me know if it helps.
