Installation Notes and Tips

Confirm the vehicle year, make, model, and tensioner direction before ordering. Match the pulley diameter, pulley width, and hydraulic actuator style to the original assembly. Inspect the serpentine belt, idler pulleys, and related accessory drive components during service, since worn parts can affect tensioner performance. For Genesis G80, Genesis G90, and Kia Stinger applications, compare the original belt path and mounting points to ensure the replacement matches the factory configuration.
