Question about 2003 Chevrolet Silverado 1500
Check to be sure the tensioner pulley is still straight,
if the bushing where it pivots wears out the pulley will tilt and
make the belt run off to one side.It takes very little play to make noise.Have seen alot of these that the power steering pulley
or pump has been changed and the pulley is pressed on too far
only takes like 1/16 of an inch to make noise.

It could be a pulley, sometimes a worn belt will do that. Check the idler pulley, tensioner pulley, and alternator pulley, then check all the rest. If an alternator bearing is going bad, it may leave you stranded someday.

You can run down to your local auto parts store and buy a serp belt tool. Or you can take a 3/8 drive ratchet, locate the 3/8 square hole in your tensioner and put the ratchet in the hole. For more leverage I put a deep socket over the ratchet handle and put a long 3/8 extention in the deep socket. This will provide ample leverage and will save buying more tools you do not need. Simply move the tensioner to the direction that takes pressure off of the belt.

SOURCE: Replaced Serpantine belt and now
Your tensioner pulley is either not mounted correctly, or is worn out...odd that it waited until you changed the serpentine belt...The tensioner pulley has a square on the back side that must fit into the correct slot on your block...I'll bet you can fix this...:)
