How do you replace the serpentine belt on a 2002 Chrysler Sebring?

To replace the serpentine belt on a 2002 Chrysler Sebring, first, ensure the engine is off and cool. Locate the tensioner pulley and use a wrench or ratchet to rotate it counterclockwise, which will relieve tension on the belt. Remove the old belt and route the new belt according to the belt routing diagram usually found on a sticker under the hood. Finally, reapply tension by releasing the tensioner and double-check that the belt is properly seated on all pulleys.
