Installation Notes and Tips

Verify the belt groove count, top width, and length against the vehicle’s original specification before installation. Confirm the exact engine and accessory drive configuration, especially on Mercedes-Benz models with notes such as Active Suspension or Active Body Control exclusions. Inspect pulleys, tensioners, and idlers for wear before fitting the new belt, and make sure the belt seats fully in every pulley groove during installation.
