422 200 05 01 Compatible Water Pump for Mercedes-Benz

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring continuous coolant circulation between the engine block and the radiator. By maintaining consistent flow, it prevents engine overheating during high-load operations typical in heavy commercial vehicle applications.

Engine compatibility and fitment

This specific model is engineered for compatibility with Mercedes-Benz SK 3255 AF trucks featuring OM 443 LA engines. It is manufactured using high-strength components to withstand the thermal stresses and mechanical demands of heavy-duty service.

Maintenance and replacement

For optimal performance, technicians should inspect the pump for signs of coolant leakage from the weep hole or unusual bearing noise during routine maintenance. It is recommended to replace the pump during timing belt or alternator belt service intervals to prevent unplanned downtime.

Troubleshooting guidance

Selecting a high-quality replacement ensures the cooling system maintains pressure and flow, protecting the engine from thermal damage and erosion of the sealing surfaces.
