To replace the serpentine belt on a 1989 Chevy truck, first, locate the belt routing diagram, usually found on a sticker near the radiator or on the underside of the hood. Use a wrench or ratchet to relieve tension on the tensioner pulley, allowing you to remove the old belt. Once the old belt is off, route the new belt according to the diagram, ensuring it sits properly on all pulleys. Finally, release the tensioner to secure the new belt in place, and double-check the alignment before starting the engine.
