Installation Notes and Tips

Verify pulley groove count, keyway style, and dimensional match before installation. Inspect the crankshaft snout, belt alignment, and surrounding front-engine components during service. Because the center bolt and washer are not included, confirm the correct fasteners are available for the vehicle before beginning the repair.
