The Multiquip 1685173350 Water Return Pipe is a genuine OEM component designed for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series equipment. Sourced directly from Multiquip, this part meets the exact specifications of the original component it replaces. It is a direct-fit replacement that installs in the same position and connects to the same coolant circuit as the factory part. Confirmed fitment covers the DA7000SSA2 and DAC7000SS super-silent generator families as well as the DLW300ES welder series.
Key Features
- Genuine OEM Coolant Integrity — Manufactured to Multiquip's original dimensional and material standards, ensuring the coolant return path maintains proper flow rate and pressure throughout the cooling circuit.
- Direct-Fit Installation — Engineered to match the original routing and connection points, allowing the pipe to seat and seal correctly without reworking adjacent components.
- Broad Series Fitment — Compatible with DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA super-silent generators and DLW300ES series diesel light welders.
- Sustained Cooling Performance — A properly functioning water return pipe keeps coolant cycling through the engine at the correct rate; a cracked or leaking pipe leads to overheating and unplanned shutdowns.
- OEM Part Number Verified — Part number 1685173350 matches Multiquip's official parts documentation, so you can order with confidence that you are receiving the correct component.
The water return pipe is a critical segment of the engine's liquid cooling circuit. Its job is to carry coolant from the engine block back toward the radiator or heat exchanger so the fluid can be cooled before recirculating. If this pipe develops a crack, a leak, or a compromised connection, coolant volume in the system drops, engine temperatures climb, and the unit will shut down to prevent serious engine damage. Replacing a worn or damaged water return pipe promptly restores the closed-loop cooling system to full efficiency and protects the engine from heat-related wear.
