The Multiquip 1627142502 Overflow Pipe Assembly is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a direct Multiquip OEM part, 1627142502 is manufactured to the same specification as the original, ensuring a correct fit within the cooling system without modification. Sourced directly through authorized Multiquip distribution, this assembly is the right choice when you need confidence in fitment and long-term performance. DHS Equipment supplies this part ready to ship for DLW400ES series machines.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specification, ensuring the correct tube diameter, fittings, and routing profile for the DLW400ES cooling circuit.
- Direct-Fit Replacement — Engineered to connect directly to existing coolant system mounting points on DLW400ES, DLW400ESA, and DLW400ESA1 models with no reworking of hose connections or brackets.
- Confirmed Fitment — Verified for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models by Multiquip part number 1627142502.
- Coolant Flow Integrity — A correctly functioning overflow pipe maintains proper coolant reservoir pressure balance, preventing overheating and protecting the engine under sustained welding loads.
- Leak Prevention — OEM-grade materials resist cracking and heat fatigue that commonly cause overflow pipe failures, helping maintain a sealed, pressure-stable cooling system.
The overflow pipe assembly routes excess coolant from the radiator cap overflow port to the coolant reservoir, managing thermal expansion within the cooling system as the engine heats and cools. This controlled flow prevents coolant loss and keeps the system pressure balanced, which is critical for maintaining safe operating temperatures during extended diesel welder operation. When the overflow pipe cracks, kinks, or its fittings fail, coolant escapes rather than recirculating — leading to low coolant levels, overheating, and potential engine damage if left unaddressed.
