I have that annoying as* chirp/squeek and have already replaced the idler pulley. It seems the problem is coming from one of the 3 A/C pulleys. Which one could it be and who has the p/n for a replacement?? Thanks!!!

Can't answer your question, but I think the some of the squealing issues may be caused by the factory belts. My idler pulley squeaked bad, but when I put on my ASP crank pulley and changed both belts, the noise went away and never came back. Just something you may want to check out.

I have suggestion on how to find the bad pulley, get a spray bottle of water ( W-D 40 can work but it might be a little messy) with a little dish soap in it and spray each pulley as close to the back side as possible as can.

Accessory Drive Belt - Squeak/Chirp Noise

BULLETIN NUMBER: 00-06-01-008

SECTION: 06 - Engine/Propulsion System

DATE: March 2000

SUBJECT: Accessory Drive Belt Squeak/Chirp Noise (Install New Double Row Idler Pulley, Generator Bracket and Serpentine Belt)

MODELS:
1998-2000 Chevrolet Camaro
1998-2000 Pontiac Firebird
Built Prior to VIN Breakpoint Y2107225 with 5.7L V8 Engine (VIN G - RPO LS1)

CONDITION: Some customers may comment on a squeak/chirp noise coming from the accessory drive serpentine belt. The noise will be most noticeable at idle and low engine speeds.
CAUSE: The serpentine belt squeak/chirp noise may be caused by misalignment between the idler pulley and crankshaft pulley. A slight rocking motion of the idler pulley causes the misalignment, which results in noise.

CORRECTION: To correct this condition on vehicles built prior to the above VIN breakpoint, install the new generator bracket, double row idler pulley and serpentine belt following Service Manual procedures.

Important: The new generator bracket can be identified by the depth of the idler pulley mounting pilot. The pilot dimension (2) on the new generator bracket is 10 mm. Dimension (2) on the previous bracket was 8.3 mm.

The way we do it at the dealer is to clean all the belts and pulleys with brake parts cleaner spray,Then put a dab of dielectric silicone GREASE on the front and back of the belts.After i do all the bulletin fixes, this finally works.It will stay quiet for a real long time unless you have an alignment problem or ran through some contaminated rain water.Good Luck
