Route the new belt
Follow the underhood diagram to loop the belt around every pulley, leaving the easiest pulley for last. Confirm each rib is centered in its grooves.
Release the tensioner and inspect
Rotate the tensioner slowly, guide the belt onto the final pulley, and let tension return gradually. Check the belt path across all pulleys before starting the engine.
