just replaced the belt.... still squeeks. At first i thought MAYBE it was my alternator bearing, but i examined it without the belt and spun it and it spins very smooth and nice...

im such an idiot though I didnt check the other pullys -____-

My tensioner solved it, although it looked and felt fine. Pretty easy to change as well, 3 bolts and you can leave the belt hang there and not have to struggle to get it back on.

Does anyone have this diagram for the v6 engine? I have one going out and I need to take the belt off to figure out which one it is. $45 seems kind of steep for what is a piece of cast steel with a bearing in it...

Do they have to be pressed in and out or can you knock it out with a hammer and a socket?
