SOURCE: Belt noise
this may be a belt alignment issue, check the relative position of all the pulleys to one another, there may be a recall on this issue, contact your local dealer.
SOURCE: serpentine belt slips off idler pulley
The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.
SOURCE: squeeling belt, have replaced idler pulley,
Try using a very small spray of silicone spray on the belt next time you're hearing the squeal. If it temporarily stops, replace the belt. Check the p/s fluid level, if it's low it could cause the pump to make noise. Also if it's low, you have a leak, check all lines, connections and pull back the bellows boots on the p/s rack (if rack and pinion). Finally, pick yourself up a mechanic's stethescope, good tool for diagnosing accesory noises. Listen to all components while duplicating the noise.
SOURCE: mazdaspeed protoge 03 is making that high pitch
That means the fanbelt on the alternator is not tight enough or needs to be changed, if the belt on powersteering goes via A/C than it might be too tight on the powersteering pulley.
SOURCE: I have a 2001 Sonata. I have a squeeling pulley.
It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps

One of the pulleys has got to be a problem. Do all pulleys spin freely with no noise or roughness or looseness? Does the AC compressor work? Was the heat setting on defrost at the time. If so the AC compressor may be seizing as it will operate when defrost is selected and spin ok by hand but be problematic when engaged
