    Hi, I have a 2000 Chevy Silverado with a 4.8L and a squeaking noise coming from one of the engine pulleys...(Noise gets louder with increasing RPMs.)...was just wondering if one of the pulleys is more common to make this noise?? anyone thoughts on which pulley it might be?...any info would be appreciated thank-you.

    Can't you tell where the squeaking/squealing is coming from if you open the hood and have a listen? It could be anything from an A/C compressor getting ready to kick it to a tensioner that needs a little lubricating.

    Last serpentine belt replacement? Should be every 60k miles and is it shiney? Which makes it squeak
    and get louder at higher RPM's...
