Drive Belt Tensioner – 07K 903 315T (Gates)

Description

Product Description

The 07K903315T Accessory Drive Belt by Gates is an OE‑quality serpentine belt designed for select Volkswagen and Audi applications. This belt drives key engine accessories such as the alternator, power steering pump (if equipped), and A/C compressor, helping ensure reliable charging performance, consistent cabin cooling, and smooth accessory operation.

Over time, belts wear from heat, load, and constant flexing. Cracks, glazing, fraying, or stretching can lead to belt squeal, reduced accessory performance, or complete belt failure. Replacing the belt with a new Gates 07K903315T restores dependable power transfer and helps prevent unexpected breakdowns.
