Thinking to change the serpentine belt on a 2007 LE (I've seen a couple videos and it looks like a bit of a pain, but doable). My question is: is it necessary to replace any of the various pulleys/tensioner? There's some chirping coming from the belt/pulley area, and I'm hoping changing the belt will solve that. But if not, maybe it's the pulley bearings that are causing the noise, so changing them may fix it. Is replacing the various pulleys (a/c, water pump, alternator, tensioner, etc.) something that is normally done on these vehicles after so many miles?
