The Multiquip C3311500504 is a genuine OEM Intercooler Hose Lower LS designed for the DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B configurations. As a direct OEM replacement sourced through Multiquip's authorized parts program, C3311500504 delivers the exact fit and material specification your generator needs to maintain proper charge air cooling. This is a lower-circuit hose, handling the connection on the cooler side of the intercooler system where a correct seal is critical to turbo system integrity. Verify your model code against the fitment list before ordering to ensure this is the right hose for your unit.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's exact material and dimension spec for the DCA400SSI4F intercooler circuit, ensuring the hose holds rated boost pressure without cracking or collapsing.
- Lower Circuit Application: — Engineered specifically for the lower intercooler hose position in the LS charge air routing, so it routes and clamps correctly without cutting or trimming on installation.
- Broad DCA400SSI4F Series Compatibility: — Fits DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B super-silent generator variants.
- Charge Air Integrity: — A failed or cracked lower intercooler hose allows boosted air to escape before the engine, causing power loss, elevated exhaust temperatures, and potential generator output instability under load.
- Direct OEM Replacement: — Part number C3311500504 cross-references directly to the original component, eliminating guesswork when ordering a like-for-like replacement during scheduled service or emergency repair.
The intercooler hose carries compressed, heat-saturated air from the turbocharger through the intercooler, where it is cooled before entering the engine's intake. The lower hose specifically connects the cooler outlet back into the intake tract, and its condition directly affects how efficiently the engine breathes under full generator load. When this hose cracks, splits, or loses its seal at the clamp, boosted air bleeds off — resulting in a drop in power output, rough running, and increased thermal stress on the engine over time.
