Checking the V-belt / poly V-belt (VW Passat B3)

The condition and tension of the V-belt must be checked as part of maintenance every 30,000 km.

The V-belt must be replaced when:

• excessive wear
• fringing of the side surfaces
• presence of traces of oil
• porosity, surface cracks

Check the V-belt tension by pressing firmly with your thumb. The belt should deflect by approximately 10 mm. Adjust the belt tension if necessary.

Note: On all models there is no need to tighten the poly V-belt, as the spring-loaded tension roller maintains the belt tension constant. For the position of the tension roller, see section "Tensioning/replacing the poly V-belt".
