How do you install a serpentine belt on a Lexus?

To install a serpentine belt on a Lexus, first ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker near the engine or in the owner’s manual, to guide the correct path for the new belt. Use a wrench or socket to relieve tension on the tensioner pulley, then slide the old belt off and the new belt on, following the correct routing. Finally, double-check the belt’s alignment and ensure it’s securely in place before starting the engine.
