NCV3 Serpentine Belt or Fan Belt [OM642]

This belt is the short belt that runs the fan on all V6 om642 motors with no rear AC.

It could also be referred to as the “fan belt”.

It is extremely short and also confusing to figure out how to replace it.

The old one must be cut off and the new belt is slowly rolled on to the pulleys as the engine is turned over by hand. There are a few videos on YouTube that explain the process.

Also Known As: 6PK691

This belt is manufactured by Continental under the line Contitech. This is the highest quality belt you can get for your Sprinter van, period.
