How do I replace the Airconditioning/power steering belt on a Grand marquis, Mercury(1992)? please show me in a diagram or print somehow

Move the Grand Marquis's serpentine belt tensioner off the serpentine belt with the serpentine belt tool. Pull the belt of the remaining pulleys by hand. Take the belt out of the engine well. Wrap the new belt around the bottom portion of the crankshaft pulley. Follow the belt routing diagram to route the belt over each remaining pulley until only the tensioner remains. Move the Grand Marquis's serpentine belt tensioner aside once more and slip the belt onto the tensioner pulley.Hold the belt in place with one hand while you move the tensioner slowly back into position with the other. Here you can fine the quality AC parts http://www.1airconditioning.com/ac_compresor.htm
