Multiquip C3310500404 Radiator Hose

The Multiquip C3310500404 is a genuine OEM Radiator Hose designed for DCA250SSI and DCA400SSI series Super-Silent generators. As a factory-sourced component, it is manufactured to the exact dimensions and material specifications required for proper coolant flow and a leak-free connection. Confirmed fitment includes DCA250SSI, DCA250SSIU, DCA250SSI-3, DCA400SSI, DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, DCA400SSI4F3PB, and DCA400SSI4F3PD variants. Sourcing the correct OEM hose ensures the cooling system performs as engineered, protecting the generator's diesel engine during extended run cycles.

Key Features

• Genuine OEM Construction — Molded to the exact wall thickness, inside diameter, and bend profile required by the DCA-series cooling circuit, ensuring full contact with factory hose clamps and fittings.
• Direct-Fit Replacement — Routes and seats exactly as the original, connecting to existing coolant ports without trimming or adapting the hose ends.
• Broad DCA-Series Compatibility — Verified for DCA250SSI, DCA250SSIU, DCA400SSI, and the full DCA400SSI Tier 4 (4F, 4F3, 4F3B, 4F3PB, 4F3PD) generator family.
• Coolant Integrity Under Load — Maintains a sealed coolant path during sustained generator operation, preventing overheating events that can cause unplanned shutdowns or engine damage.
• Fuel System Safety Relevance — A compromised radiator hose on a diesel generator can lead to rapid coolant loss, elevated operating temperatures, and potential engine seizure — replacing at the first sign of cracking or swelling is critical.

A radiator hose carries engine coolant between the engine block and the radiator, allowing heat absorbed from combustion to be transferred away and dissipated. On diesel-powered generators like the DCA250SSI and DCA400SSI, maintaining a sealed, unrestricted coolant path is essential for stable operating temperatures during long duty cycles. When a radiator hose deteriorates — through cracking, swelling, or collar softening — coolant loss occurs quickly, leading to overheating, automatic shutdown, or in severe cases, permanent engine damage. Replacing a worn hose with the correct OEM part restores full cooling system integrity and keeps the generator running within its designed temperature range.
