dunno where exactly it's coming from, but there is a really high pitched squeeling noise coming from under my hood. sound like a leak somewhere--but there are no leaks, i've look everywhere. it seems to be the strongest sounding right around the throttle body. any help or suggestions would be great. thx a lot.

actually, i noticed my belt is offsetted a little on the pulley underneath the alternator (not sure which pulley this is) but i know that for a while it was like this, it fixed itself, and now it's back the same way. maybe 1 mm off of the pully that it's supposed to be.
do you think this is it?
how do i go about fixing this? is replacement of the pulley and/or belt necessary?2000 NBM M6 Camaro Z28<br />323/335

99% of the time if you hear a squealing noise then its a belt. I cant think of anything else that would make that noise.<b>Black 1996 3.8L Firebird A4</b><br />--------------------------<br />Custom CAI, Flowmaster Dual Exhaust, 160 Deg Thermo, BMR ShockTower Brace<br />JVC mp3 HU, two 12\" Infinity Kappa Perfects, Infinity 6.5\" components, JBL 600.1 & 80.4 amps <br /><a href=\"http://community.webshots.com/album/479229363CPbPiz\" target=\"_blank\">Pics</a>

You could remove the belt and hand turn all of the accessories to see if they feel smooth and and quiet. You might also start the engine for a few seconds to see if the noise is still there. Not long though, your water pump won't be working. Might as well have a new belt handy to put back on when you're done.

i ran it without the belt--didn't hear a squeak.
i ran it with a new belt, heard a very, very minor squeak but i think it's the tensioner pulley because the other belt had been sitting offsetted on there for a while and the pulley got a little worn down. it's either that pulley or it's the alternator pulley. either way, both look fine and i don't think a little squeak out of them is a big deal. do you guys?
btw, the new belt doesn't come off of that pulley like the old one did.2000 NBM M6 Camaro Z28<br />323/335
