Engine Noise

What is your question?

I have a 2005 Sedona, the engine has a noise coming from the pulley side of the engine. It sounds like it is coming from one of the pulley's. We had a mechanic look at it last year before the noise started and said that the A/C compressor bracket was part of a recall and might start making noise. To me it sounds like a bad bearing on one of the pulley's. Is there somewhere on-line to get an engine manual for the belt and pulley lay out. Thanks for the help in advance.
