squeaking will not stop, i have changed my alt., and my tensioner pulley! changing them two helped out allot, but still have that high pitch squeaking! i believe its the pulley that to the left (passengers side) of the underdrive pulley. its not on the serpentine belt system its on the AC or whatever that system is? what is that pulley called? is there a pulley system diagram or something i am missing out on? also what system of pulleys is that on called? thanks for the help guys!!!

Is it the A.I.R. pump? It only runs for a few minutes on startup to get warm exhaust running through the cat, so it won't clog. Then, when the car warms up, it turns off because it doesn't need to heat the exhaust anymore.

I was having the same issues, ended up being that the underdrive pulley was not in all the way, so it would rub the side of my belts. once they were warm they would stop.

Same problem here when it's wet, but haven't tried to fix the problem yet so not quite sure which belt it is on mine.

if its the belt and its on right try taking a candle and hold it against the belt while the car is idleing....

I heard it could be the balancer that is causing your problems.

i had that problem for awhile when i just bought mine, try changing the idler pulley, its a smaller one that has nothing running off of it, it isnt ridged and usually the bearings are bad in them, try a search for some pictures. other than that it might be your water pump???

get an engine stethoscope put the probe the brackets of the pulleys this will let you know which one is squeaking. btw there are 2 idler pulleys on our cars. hope this helps

I duno weve had a lot of car with squeaky belts, weve just taken a wax candle and with the car running put the candle on the belt and let it rub until the noise goes away....its worth a shot cant hurt anything..

i have the same prob. at start up my belt makes noises. looked close at the crank pulley and saw that it was also wobbling a lil. im thinking its the balancer.

I had the same squeaking at startup when cold and it ended up being that the belts were slipping, all I did was spray some belt conditioner spray that I picked up at pep boys, and at first it went from squeaking when cold, to a sticky belt sound all the time for a few miles but now its silent, problem solved for me.

Repack the idler pulley with new grease, then try repacking the two tensioner pulleys. There is a thread that shows how. There is one tensioner for the main belt and one tensioner for the A/C belt. Then maybe the alternator, or water pump, or even the power steering pump can squeak. Don't use belt dressing, it will just cause you more frustration.

Hope this helps.
