How do you change the serpentine belt on a 2007 Jeep Compass?

To change the serpentine belt on a 2007 Jeep Compass, first, ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker near the engine, then use a wrench or socket to relieve tension on the tensioner pulley and remove the old belt. Install the new belt following the routing diagram, ensuring it sits properly on all pulleys. Finally, recheck the belt alignment and tension before starting the engine.
