The Multiquip 1585273340 is a genuine OEM Water Return Pipe designed for DLW and DAC/DA generator and welder series equipment, including DLW400ES, DLW300ES, DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, and DA7000SSA2GH models. As a factory-sourced component, it meets the original engineering specifications for the cooling system on these diesel-powered units. Sourced direct from Multiquip, part number 1585273340 ensures a correct, hassle-free installation with no guesswork on fitment.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original cooling circuit specifications, ensuring the correct internal diameter, wall thickness, and connection geometry for the water return circuit.
- Direct-Fit Replacement — Engineered to connect directly into the existing cooling line routing on DLW and DAC/DA series machines, using the same attachment points as the original part.
- Broad Series Compatibility — Confirmed fitment across DLW300ES, DLW400ES, DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, and DA7000SSA2GH diesel welders and generators.
- Cooling System Integrity — A properly functioning water return pipe keeps coolant flowing back to the radiator at the correct rate, preventing heat buildup that can lead to overheating and engine damage.
- Leak-Risk Reduction — Replacing a cracked, corroded, or worn return pipe eliminates a common source of coolant loss that can go undetected until serious engine damage has occurred.
The water return pipe is a critical component of the engine cooling circuit in diesel-powered generators and welders. It carries coolant from the engine back toward the radiator or cooling reservoir, completing the circulation loop that regulates operating temperature. When this pipe cracks, corrodes, or develops a leak, the engine loses coolant volume and cooling efficiency — leading to overheating, unplanned shutdowns, and potential long-term engine damage if not addressed promptly.
