How do you change belt in 91 dodge dynasty?

To change the serpentine belt on a 1991 Dodge Dynasty, first, ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker near the radiator or under the hood. Use a wrench to relieve tension on the belt by rotating the tensioner pulley, then slide the old belt off the pulleys. Install the new belt following the routing diagram, ensuring it is properly seated on all pulleys, and release the tensioner to apply tension to the new belt.
