Poly V-belt — checking condition (VW Caddy 3)

Turn the engine at the vibration damper/belt pulley with a socket wrench.

Check the poly V-belt (1) for the following defects:

• breaks in the bearing layer (tears, cord damage, cross-sectional breaks),
• stratification (top layer, cord threads),
• tearing out of the bearing layer,
• delamination of cord threads at the edges,
• edge wear (material erosion, thread peeling, edge hardening (glassy surface), cracks on the surface),
• traces of oil and grease.

If the above signs are detected, the poly V-belt must be replaced. This way, you can avoid belt failure and, consequently, malfunctions. Replacing the poly V-belt is a service solution.
