Answer
Nick, this is a more complicated job than one might expect. If you have tools, ability, and determination you can do it. Remove the under engine shield (pay attention to fastener location). Remove the fan clutch (32mm fan clutch nut with left hand thread). Remove the fan shroud. It is retained by plastic push rivets. Move the AUC sensor and the Electric fan connector off the shroud and it should pull straight up. Note the lugs that fit into the bottom of the radiator upon reinstall. Note belt routing before removal. Remove cap from main belt tensioner pulley and turn pulley clockwise to release main belt and push aside. Carefully remove battery cable connector and use masking tape to cover the cable end so it doesn't arch out when touching metal. Remove other electrical connector from alternator. Remove Idler belt pulley. Place a clean drain pan under alternator and remove six outer retaining bolts and remove alternator cartridge. Replace alternator and reassemble all. Refill cooling system  and bleed excess air. Make sure the battery has been charged BEFORE starting engine. The alternator has a better shot at life if it doesn't have to charge a dead battery on its first run. Good luck.
