How do you change a serpentine belt on a 2006 dodge magnum with a 2.7L V-6?

To change the serpentine belt on a 2006 Dodge Magnum with a 2.7L V6, first, ensure the engine is off and cool. Locate the tensioner pulley and use a wrench or socket to relieve tension by rotating the tensioner arm clockwise. Remove the old belt by noting its routing or referring to a belt diagram, then install the new belt following the same path. Finally, release the tensioner and ensure the belt is properly seated on all pulleys before starting the engine.
