Accessory Drive Squeak.... again!
I had the well-known chirping sound from the accessory drive belt. I replaced the idler pulley (TSB #99-06-01-007). The chirp went away for 3 days - now its back :( .
specified torque of the mounting bolt is 37 lb ft. Couldn't get a torque wrench in there, but I'm pretty sure it is not over-torqued.
Anybody have any experience with this?

My 2001 has an appetite for serpentine belts and idler pulleys. I'm on my third pair of both (original and then replaced twice, last was in July 2001). I've noticed a little 'noise' from that area and suspect the belt is getting ready to retire again.
I don't think the engine should have such an appetite for serpentine belts and pulleys...

Yes, I had about 2 months worth of fun tracking the noise down. I replaced the idler pulley twice, the tensioner pulley twice and went through about 5 belts of all different brands. Sometimes it would fix it for a couple of days up to a week, and others it wouldn't fix it at all! It turned out to be the runout on the harmonic balancer/pulley. It had a very slight wobble, therefore the chirping sound and the wearing out of the drive belt! The dealer replaced it about 2 months ago and I haven't had any problems since!
