Applications

The OTC 6617 Alternator Pulley Service Kit is essential for technicians working on a wide range of modern vehicles equipped with OAP and OAD alternators. These include late-model foreign and domestic vehicles, commonly found in brands such as VW, Toyota, Honda, Chrysler, Chevrolet, Audi, and BMW.
