How do you replace v belt on Mercedes sprinter van?

To replace the V-belt on a Mercedes Sprinter van, first, ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker in the engine compartment, and then use a wrench to relieve tension on the tensioner pulley. Remove the old belt and install the new one, following the routing diagram carefully. Finally, check the tension and ensure everything is properly aligned before starting the engine.
