OE Quality Water Pump for Mercedes-Benz Applications

The Rein WPR0017 engine water pump is an OE-quality replacement built for direct fitment on select Mercedes-Benz and Chrysler applications. It is engineered to support proper coolant circulation, stable operating temperatures, and reliable long-term service in vehicles such as the Mercedes-Benz S500, E500, ML500, and related models.

• OE-style direct replacement for factory water pump applications
• Silicon carbide seals for improved durability and service life
• OE-designed bearings to support extended pump life
• Original casting specifications for proper fitment and coolant flow
• Includes OE-style gaskets and/or O-rings for replacement of worn sealing components
• Backed by a 4-year / 50,000-mile warranty

Built for Proper Cooling System Performance

Rein WPR0017 is manufactured to original casting specifications so it installs like the factory unit and maintains the coolant flow needed for consistent engine cooling. The pump uses silicon carbide seals and OE-design bearings to meet or exceed OEM standards for service life. This makes it a practical choice for Mercedes-Benz water pump replacement on models including the SL500, CL500, E430, and ML320, especially when the original pump shows signs of wear or leakage.

This part cross-references URO 1122000401 for the same application.

Common Problems This Water Pump Can Address

• Coolant leakage from a worn pump seal
• Overheating caused by reduced coolant circulation
• Noise from failing pump bearings
• Loss of cooling efficiency in high-mileage Mercedes-Benz engines
• Fitment issues from using a non-OE-style replacement pump
