How do you install a serpentine belt on a 2000 Silverado?

To install a serpentine belt on a 2000 Silverado, first ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker near the radiator or on the engine cover, to understand the correct path. Use a socket or wrench to relieve tension on the tensioner pulley, then slide the belt off the pulleys. Finally, route the new belt according to the diagram and release the tensioner to secure the belt in place.
