How do you change the alternator drive belt on 2002 Concorde plus?

To change the alternator drive belt on a 2002 Chrysler Concorde, first, disconnect the negative battery terminal for safety. Then, locate the belt tensioner and use a ratchet or wrench to relieve tension on the belt. Remove the old belt from the alternator and other pulleys, then route the new belt according to the belt routing diagram typically found on a sticker under the hood. Finally, reapply tension on the belt using the tensioner, double-check the alignment, and reconnect the battery terminal.
