The Multiquip Y0602012721 Radiator is a genuine OEM radiator designed for the DLW400ESA4 diesel light welder. As a direct OEM replacement sourced through Multiquip's authorized parts program, Y0602012721 is manufactured to the exact specifications of the original unit — ensuring correct mounting dimensions, coolant flow capacity, and tank fitment for the DLW400ESA4 platform. Keeping the cooling system in top condition is critical on a diesel welder that runs hard and long, and this radiator delivers the thermal performance the machine was engineered around.
Key Features
- Genuine OEM Cooling Capacity — Built to the exact heat-rejection specification of the original DLW400ESA4 radiator, not a general-purpose substitute.
- Direct-Mount Replacement — Matches the original core dimensions, inlet/outlet port positions, and bracket holes for a bolt-in installation with no fabrication needed.
- Confirmed DLW400ESA4 Fitment — Verified for the Multiquip DLW400ESA4 diesel light welder series; verify your model before ordering.
- Protects Engine Longevity — A properly functioning radiator prevents thermal overload that can warp cylinder heads, damage seals, and force costly engine repairs on a hard-working diesel.
- Authorized OEM Supply Chain — Sourced directly through Multiquip's authorized parts network, so you receive a part held to the same quality controls as the original build.
The radiator is the heart of the engine's liquid cooling system. It dissipates heat by circulating coolant through a finned core where airflow carries that heat away from the engine. On a diesel light welder like the DLW400ESA4, which runs continuously under electrical load, maintaining stable coolant temperatures is essential to protecting the engine and sustaining consistent weld output. When a radiator develops a leak, becomes clogged, or fails, coolant temperatures rise rapidly — triggering shutdown protection or, if left unaddressed, causing serious internal engine damage.
