Serpentine Belt Replacement

[cexsiman]

I was cleaning up my engine bay a little and noticed that i really need to replace my serpentine belts. Does anyone know the part numbers for the belts, and how to replace them? i know the general aspect, take belt off, put new belt on deal, just dont know what size sockets it takes, or where the tensioner is, or how hard of a job it is. and as always a picture or two says thousands of words. (im just hoping for the right words)

thanks all.

ive checked it out before, i was more or less just asking for engine specific tips / things to look out for / easiest way to get in there and all that.
