Installation Notes and Tips

Verify the belt routing, rib count, and measured length against the vehicle’s accessory drive layout before installation. This belt is listed for main drive use only, and several Dodge applications require dealer air or specific A/C and GVW configurations, so confirm the exact vehicle build before ordering. Inspect pulleys, tensioners, and idlers for wear before installing the new belt to help prevent premature belt damage.
