Engine Noise At Startup?

[crzyhrse99]

im getting a chirping sound at startup from my 99 gt. sounds like the serpentine belt but it looks fine and is not even a year old. have had u/d pulleys on for about 3 years and had to get new belt b/c somehow the old one was getting chewed up. had it checked out and a smaller belt put on, everything was fine untill now. after car is warm there is no problem. any solutions?

Try giving it a squirt with WD 40 to see if it goes away. If not, it could be your idler pully, give that a shot.

Probably the belt. Like CanadaStang said, pop the hood while it is making the noise. spray some wd40 on the belt and see if it stops if it doesn't start spraying a little on hub of each pulley to see which one it is. The wd40 won't fix the problem, just helps to pinpoint it.

An old hot rodder trick of getting rid of the belt squeak would be to rub the edges down with a bar of soap. Spraying WD-40 on it will work as well, but will also contribute to the degrading and deterioration of the rubber at the same time….where soap will not. Try spraying the areas of the belt surface down with a little brake and parts cleaner first, to ensure that the squeaking is not just a result of belt dust.
