The Multiquip D5311501104 Radiator Hose is a genuine OEM radiator hose designed for the DLW400ESA4 diesel light welder. Sourced directly from Multiquip, this part matches the original equipment specification for material, diameter, and routing — no trimming or adaptation needed. If you're servicing a DLW400ESA4 and need a confirmed-fit coolant hose, D5311501104 is the correct OEM part number to order.
Key Features
- OEM-Grade Hose Construction — Manufactured to original equipment material and wall-thickness standards, ensuring proper heat and pressure tolerance for diesel welder cooling systems.
- Direct-Fit Replacement — Matches the original routing, end diameter, and length of the factory hose on the DLW400ESA4, so installation is straightforward with standard hose clamps.
- Confirmed Fitment for DLW400ESA4 — Verified OEM part for the Multiquip DLW400ESA4 diesel light welder series.
- Maintains Coolant Flow Integrity — A correctly fitted radiator hose keeps coolant circulating between the engine and radiator at the right pressure, preventing overheating under sustained welding loads.
- Prevents Coolant Loss and Engine Damage — A cracked or collapsed hose can cause rapid coolant loss and engine overheating; replacing with the OEM hose restores the system to proper operating condition.
The radiator hose carries engine coolant between the engine block and the radiator, allowing heat generated during operation to be dissipated before the coolant cycles back through the engine. On a diesel light welder like the DLW400ESA4, where the engine runs under sustained load to produce welding current, consistent coolant flow is critical to preventing thermal damage. When a radiator hose cracks, swells, or collapses, coolant pressure drops and the engine temperature rises rapidly — making timely hose replacement an essential part of routine maintenance.
