Common Problems This Part Can Address

• Coolant circulation loss from a worn or failing water pump

• Temperature instability in Mercedes-Benz 300D, 300SD, 300TD, and 300SEL cooling systems

Installation Notes and Tips

Verify the engine design and serial number notes before ordering, especially on 300SEL applications. Confirm that the replacement matches the original equipment type and metal impeller specification. Inspect the cooling system condition during service, including hoses, thermostat, and coolant quality, so the new pump can operate under proper system conditions.
