If your OM651 Sprinter has experienced water pump failure leading to coolant contaimination of the vacuum system, this kit includes all the parts that Mercedes specifies need replacing. Includes:
- Vacuum Reservoir
- Vacuum Changeover Valve
- Water Pump with Gasket- your choice of new Graf pump or remanufactured OE Mercedes pump. Both pumps are "switchable" design with vacuum controlled impeller shield.
A new water pump carrier assembly bracket is available. This is a revised part that should be more reliable than the factory design.
