The Multiquip C3311500804 is a genuine OEM Lower RS Intercooler Hose designed for DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B variants. As a direct OEM replacement, this hose meets the original engineering specifications set for these units, ensuring a correct, trouble-free installation. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence knowing you are receiving an authentic component.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications required for the intercooler circuit on DCA400SSI4F series generators, not a generic hose cut to fit.
- Direct-Connect Replacement — Engineered to match the lower RS routing path exactly, allowing the hose to seat correctly on the intercooler and engine ports without reworking clamps or fittings.
- Broad DCA400SSI4F Series Coverage — Compatible across DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B configurations, including Sunbelt-spec units.
- Sustained Charge-Air Integrity — A correctly sealed intercooler hose maintains proper boost pressure delivery to the engine, supporting full rated generator output and efficient fuel combustion under load.
- Boost Circuit Safety — A cracked or collapsed intercooler hose can cause uncontrolled pressure loss in the charge-air system, leading to engine derating or unplanned shutdown — replacing with an OEM hose restores system integrity.
The intercooler hose carries compressed, heat-soaked air from the turbocharger to the intercooler (or from the intercooler to the engine intake) where it is cooled before combustion. On a large diesel generator like the DCA400SSI4F series, maintaining a sealed and unobstructed charge-air path is critical to achieving full power output and keeping exhaust emissions within spec. When this hose deteriorates — through cracking, swelling, or clamp-seat collapse — boost pressure leaks into the engine bay rather than reaching the cylinders, causing the engine to run rich, lose power, or trigger protective shutdown. Replacing the C3311500804 Lower RS Intercooler Hose with a genuine OEM part restores the charge-air circuit to its original condition.
