Inspect the pulleys and tensioner when replacing a serpentine belt. Check for misalignment, glazing, or debris that can damage a new belt. If the old belt has cracks, missing ribs, or a glazed surface, replace it before it fails. For drives with more than one belt, replace belts in sets to keep wear even.
