It is not difficult to replace the serpentine belt. There are several short video clips on You tube this one is pretty good.
Alignment of the belt ensuring all the grooves align properly is important tighten the belt so there is no slack (do not over tighten or you shall shorten the life of the driven component (ie water pump alternator, power steering pump). Run the engine for a few minutes switch off and recheck belt tension adjust as required.
