Febi 172281 Engine Water Pump

Febi Engine Water Pump for Mercedes-Benz V8 Cooling

Febi part number 172281 is an engine water pump built for Mercedes-Benz applications that require a durable cooling-system replacement. It uses a grey cast iron housing, a metal impeller with 6 fan blades, and rubber/metal sealing materials for a service-ready fit in the cooling circuit.

The febi product line focuses on OE-style replacement components for European vehicles, and this water pump follows that approach with material choices suited to demanding engine cooling operation. If you are replacing a worn Mercedes-Benz water pump on a GLS550, SL550, CLS550, E550, S550, GL550, CL550, GL450, or ML550, part number 172281 is a direct-reference option to verify against your original unit.

Key Features

• Grey cast iron housing for strength and thermal stability
• Metal impeller construction for consistent coolant movement
• 6 impeller blades for controlled coolant circulation
• Rubber / metal sealing material for sealing interface support
• Febi part number 172281 for catalog and cross-reference lookup

Detailed Description

This engine water pump is designed for Mercedes-Benz cooling systems that rely on a mechanically driven pump to circulate coolant through the engine and radiator. The grey cast iron housing provides a rigid mounting body, while the metal impeller is built to move coolant efficiently under operating temperature changes. The 6-blade impeller design and rubber/metal sealing materials support proper coolant flow and sealing at the pump interface. This part number 172281 is listed for multiple Mercedes-Benz V8 models, including 2012-2017 E550 and S550, 2013-2019 SL550, and 2017-2019 GLS550 applications.

This part cross-references Mercedes-Benz OE numbers 157 200 01 07 and 278 200 00 07 for the same application.

What It Helps Address

• Coolant leakage from a worn pump housing or seal area
• Overheating caused by reduced coolant circulation
• Noise from a failing impeller or internal pump wear
• Temperature fluctuation from inconsistent coolant flow
• Cooling-system service needs on Mercedes-Benz V8 models

Installation Notes and Tips

Verify the original part number and engine application before installation, especially on Mercedes-Benz GLS550, SL550, CLS550, E550, and S550 models. Inspect the cooling system for contamination, hose condition, and gasket surface cleanliness before fitting the new pump. Proper coolant fill and bleeding procedures are important after replacement to help restore stable operating temperature.

Quality Assurance

Febi is a recognized aftermarket brand for European vehicle replacement parts, and this water pump is built with specified housing, impeller, and sealing materials to match the demands of the application. Confirm fitment against the vehicle’s original water pump and OE reference numbers before installation.
