The Multiquip C3311500604 is a genuine OEM Intercooler Hose Upper LS designed for the DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and related variants. As a factory-sourced component, it delivers the exact dimensions, material grade, and routing configuration required for a correct, leak-free installation. Sourced directly from Multiquip, this part ensures your DCA400SSI4F series generator stays running at the output and efficiency levels it was engineered to deliver. Verify your model code against the fitment list to confirm compatibility before ordering.
Key Features
- OEM-Grade Hose Construction — Manufactured to the same pressure and temperature tolerances as the original, ensuring the intercooler circuit performs without restriction or heat-related degradation.
- Direct-Fit Upper LS Routing — Matches the original hose length, diameter, and bend profile exactly, connecting to the upper intercooler port without trimming or adapter fittings.
- Confirmed Fitment for DCA400SSI4F Series — Compatible with DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and associated super-silent generator variants.
- Protects Turbocharged Engine Performance — A sound intercooler hose maintains correct charge-air pressure to the engine; a cracked or failing hose causes boost loss, overheating, and power output drop.
- Fuel System and Emissions Compliance — Proper charge-air delivery is critical to Tier 4 emissions compliance; this OEM hose maintains the sealed intake path the Tier 4 fuel system depends on.
The intercooler hose routes compressed, heat-saturated air from the turbocharger through the intercooler and into the engine's intake manifold. The upper hose specifically handles the high-pressure side of this circuit, carrying hot compressed air into the intercooler core where it is cooled before combustion. When this hose cracks, collapses, or loses its seal, charge-air pressure drops, the engine runs hotter, fuel efficiency falls, and on Tier 4-compliant machines, the generator may fail to meet its rated output or emissions threshold. Replacing a worn upper intercooler hose promptly restores full charge-air flow and protects both engine longevity and generator performance.
