I have narrowed it down to the belt that is driving the water pump and alternator, but don't know why. I removed the air pump, and forced a belt from auto zone in its place.
I thought the a/c or power steering pulley was causing the squeeling, because sometimes while idleing at a stop light or so, it would start squeeling, if I turned off the a/c it would stop. Then I took that belt off completely, and started the car this morning, and it squeeled again. WHY??
