Multiquip 1625973520 Water Pump Flange D905-EBG2

The Multiquip 1625973520 Water Pump Flange D905-EBG2 is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. Sourced directly from Multiquip, this flange is manufactured to the exact tolerances required by the D905-EBG2 engine cooling system, ensuring a proper seal and correct coolant flow routing at the pump interface. Genuine OEM specification means this part matches the original component your machine shipped with, so you can restore the cooling circuit with confidence.

Key Features

• Genuine OEM Cooling System Integrity — Manufactured to the precise sealing and dimensional tolerances required at the D905-EBG2 water pump interface, preventing coolant leaks that can lead to engine overheating.
• Direct-Fit Replacement — Engineered specifically for the D905-EBG2 engine's pump mounting configuration, allowing straightforward installation against the original bolt pattern and mating surfaces.
• Compatible with DLW400ES Series — Confirmed fitment for DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welder models.
• Maintains Coolant Flow Efficiency — A correctly seated flange keeps the water pump circuit sealed and operating at designed flow rates, protecting engine temperature stability during continuous welding operations.
• Verified Multiquip Part Number — Stocked and sold under part number 1625973520, eliminating guesswork when cross-referencing your service manual or parts diagram.

The water pump flange serves as the mounting and sealing interface between the water pump and the engine block's coolant passages on the D905-EBG2 engine. It directs coolant from the pump into the engine's internal galleries and back out to the radiator, maintaining the thermal regulation the engine depends on under load. When the flange cracks, warps, or develops a failed sealing surface, coolant escapes the circuit, coolant pressure drops, and the engine becomes vulnerable to thermal damage — making prompt replacement critical to keeping the welder operational.
