The Multiquip 1624173350 Water Bypass Hose is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a factory-sourced part, it meets the same specifications as the original hose installed at the time of manufacture, ensuring a direct, correct-fitting replacement for the cooling system. DHS Equipment stocks this part to help you get your machine back in service with confidence.
Key Features
- Genuine OEM Cooling System Integrity — Manufactured to the exact material grade and dimensional tolerances of the original hose, maintaining proper coolant flow and pressure throughout the bypass circuit.
- Direct Replacement Fit — Engineered to connect to the same ports and routing as the factory hose, requiring no trimming or adaptation during installation.
- Confirmed Fitment — Verified for use on DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welder models.
- Cooling System Performance — A correctly functioning bypass hose keeps engine coolant circulating at the right temperature; a cracked or collapsed hose can lead to overheating and unplanned downtime on the worksite.
- Exact Part Number Match — Part number 1624173350 cross-references directly to Multiquip OEM documentation, so you can order with confidence that you are receiving the correct hose for your machine.
The water bypass hose routes engine coolant around a specific point in the cooling circuit — typically bypassing the thermostat or radiator during cold starts — to help the engine reach and maintain its correct operating temperature. Without a properly sealed and flexible bypass hose, coolant can leak or flow incorrectly, causing the engine to run too hot or too cold and accelerating wear on internal components. Replacing a worn, cracked, or collapsed bypass hose restores the integrity of the entire cooling circuit and protects the engine from heat-related damage.
