Find the tensioner pulley. Use a straight wrench (I believe a 14mm) and turn the tensioner pulley bolt (the one in the middle of the pulley) counter clockwise (you may need an extension Pipe). This will release tension on the belt then slide the belt off. The tensioner pulley bolt is a reverse thread so it will not come loose when attempting to turn it counter clockwise. Slide the new belt on from the bottom up then turn the tensioner pulley counter clockwise (releasing tension) with one hand while sliding the belt over the alternator pulley (a long screwdriver wedged against the side wall can help get the belt onto the pulley) then allow the tensioner pulley to return to its normal position.
