Hi Yeineken. Thanks for the DIY, this will come in handy soon. My car at 85K is making a squeaking noise (video here) and I suspect it's one of the pulleys but haven't isolated it yet. Did you figure out which one was bad, and what did you need to change? Thanks.
Actually it turned out my oil filter housing gasket failed and was leaking oil onto the belt causing the noise. I would still think about replacing the belts and pulleys as the do fail and having that happen on the highway could cause some serious damage.
