Verify pulley diameter, width, bearing bore, and belt type before installation. Confirm the mounting style and belt routing match the original tensioner assembly. Inspect the serpentine belt, idler pulleys, and related accessory drive components at the same time to avoid repeat service. For fitment verification, match the vehicle application to the original part number and system layout.
