Pretty easy to do actually. There's a pulley that just puts tension on the belt, on the left hand side of the engine (if you're looking at the engine), kinda underneath teh power steering pump. That pulley is connected to a long threaded rod with a hex head on the end of it. First you loosen the pulley, then you crank on this threaded rod until it moves enough to remove the old belt. Reverse to install.
