Hi,
The video gives you a step by step tutorial how to replace the ribbed drive belt of the Porsche 997-2 Carrera S with the 3.8l engine having direct fuel injection. The repair itself isn't very complicate when you know how to do it and how to substitute special tools. The video demonstrates you both. Replacing the belt and air filters is indicated any 90000 km or 6 years.

The video has a German soundtrack but English subtitles are added to YouTube. If you don't see them by default, watch the video directly at YouTube and press the subtitle button below the frame.
Enjoy it,
Jürgen
