Multiquip D5311500203 Hose Radiator Upper - OEM Replacement Part

The upper radiator hose is a critical cooling system component that channels hot coolant from the engine to the radiator for heat dissipation in Multiquip welding equipment. This high-temperature reinforced hose must maintain a secure, leak-free seal under constant thermal cycling and pressure fluctuations. A failing upper radiator hose can cause coolant loss, engine overheating, and costly downtime on the job site.

Designed specifically for Multiquip DLW-series diesel welders, this OEM hose features factory-correct dimensions, bend radius, and connection points to ensure proper fitment and optimal coolant flow. Replacing a cracked, bulging, or softened radiator hose before failure prevents contamination of the cooling system and protects your welder's engine from heat-related damage. Regular inspection of radiator hoses should be part of your preventive maintenance routine, especially in high-temperature operating environments.
