T5,G4 Cam Belt Tensioner - 3.2 VR6

This replacement tension pulley with integrated bearing is designed for the auxiliary ribbed belt system on Volkswagen T5 Transporters fitted with the 3.2 VR6 petrol engine. It is a direct-fit replacement component used on the alternator drive system, ensuring correct belt tension, smooth rotation, and reliable operation of engine-driven accessories.

What this part does

The tension pulley guides and stabilises the ribbed auxiliary belt while maintaining correct belt alignment and tension. This allows driven components—such as the alternator—to operate efficiently without belt slip, vibration, or noise. A worn or noisy pulley bearing can lead to belt squeal, uneven belt wear, charging issues, or complete belt failure.

How it works

Mounted within the auxiliary belt system, the pulley rotates continuously with the belt. Its sealed bearing allows smooth, low-friction operation, while the pulley’s grooved surface ensures the belt tracks correctly. Replacing a tired or seized pulley restores correct belt movement and protects surrounding components from unnecessary strain.
