Just wondering if anyone has any tips on how to locate a squeak from the alternator, water pump, power steering pump etc if you have a serpentine belt. I have removed and replaced the belt. While the belt was off I tried spinning the above mentioned parts by hand but was not able to spin them fast enough to produce the squeak. After putting the new belt on I started it up and as always the squeak was there and squeaks for about 15 minutes, then goes away. Any ideas on how I can spin these parts one at a time to see if I can find the culprit? The motor is a 1989 Chevy 4.3 and I have not replaced any of the above parts except the belt.......thanks.
