Key Features
- Genuine OEM Cooling System Integrity — Manufactured to the exact material grade and dimensional tolerances required for the V1305-E2B engine coolant circuit, ensuring proper sealing and flow.
- Direct Installation Fit — Matches the original bolt pattern and port configuration of the DLW400ES cooling system, dropping in without rework or adaptation.
- Confirmed Fitment — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welder models.
- Coolant Containment Performance — A correctly seated water flange maintains pressurized coolant flow to the engine; a cracked or warped flange causes coolant loss, overheating, and unplanned shutdown mid-job.
- Engine Protection Compliance — On liquid-cooled diesel equipment, maintaining the integrity of every coolant junction point is essential to preventing thermal damage to internal engine components.
The water flange is a structural coolant passage fitting that connects and seals sections of the engine's liquid cooling circuit. It directs coolant flow between the engine block, hoses, and the cooling system at large, maintaining the operating temperature needed to protect the diesel engine under load. When a water flange cracks, warps, or develops a leak, coolant escapes the system and engine temperatures climb rapidly — leading to overheating, potential head gasket failure, and costly engine damage if not addressed promptly.
