I've got a 1998 K2500 with a 5.7 Vortec and there a high pitch squeal coming from the belt area. It mostly does it when the engine is warm but it doesn't do it all the time. The weird part about it is that the noise continues for a couple seconds after the engine has been shut off. Alternator has recently been replaced but it made the noise before and after replacing it.
Hopefully someone here can help me since it's super loud and really annoying.
