Volkswagen Passat B5 alternator belt tensioner replacement

This is the way to replace the alternator belt tensioner in Volkswagen with a 1.9 TDI AFN engine without the front removing.

The generator belt tensioner provides a tight fit of the belt, which transmits torque to the generator and ensures the vehicle electrical appliances operation and the battery charging. The generator cannot fully fulfill its role if the tensioning mechanism has failed.

The current review’s author tells about the way he replaced VW Passat B5 alternator belt tensioner. However, he did not take off the «car front» and performed all the operations directly through the hood. The operation doesn’t require any special tools and skills.
