The Multiquip D5267300004 Cooling Fin is a genuine OEM component designed for the DLW400ES series diesel light welder. Sourced directly from Multiquip, this part meets the original design specifications for the DLW400ES, DLW400ESA, and DLW400ESA1 models. Keeping the correct cooling fin in place ensures your welder maintains safe operating temperatures during extended use on the jobsite.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the DLW400ES cooling system, ensuring correct heat dissipation characteristics.
- Direct Drop-In Replacement — Engineered to mount in the exact position as the original fin, with no fitment modifications needed to the surrounding cooling assembly.
- Confirmed Fitment — Verified for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models.
- Sustained Thermal Management — A correctly installed cooling fin channels airflow efficiently across the engine, helping prevent heat buildup that can lead to power loss or premature engine wear.
- Electrical Safety Compliance — Proper cooling protects sensitive electrical and welding output components from heat-related degradation, supporting consistent arc performance and safe operation.
The cooling fin is a structural component of the engine's air-cooling system, designed to increase surface area and transfer heat away from the engine block into the surrounding airflow. On air-cooled diesel engines like those found in the DLW400ES welder, fins play a direct role in controlling operating temperature during sustained welding or generating loads. A cracked, broken, or missing fin reduces the engine's ability to shed heat, which can cause the unit to run hot, trip thermal protection systems, or accelerate internal wear over time.
