The Multiquip M5311500303 is a genuine OEM Inter-Cooler Hose designed for the DCA250SSI, DCA250SSIU, and DCA250SSI-3 ultra-silent diesel generators. As a direct OEM replacement, this hose is manufactured to the exact material and dimensional specifications of the original component, ensuring a correct, trouble-free installation. Sourced directly through Multiquip's authorized parts network, the M5311500303 is the correct part for maintaining peak intercooler system performance on these DCA-series units.
Key Features
- Genuine OEM Construction — Manufactured to exact pressure and temperature tolerances required by the turbocharged diesel intercooler circuit, not a generic hose approximation.
- Direct Bolt-On Replacement — Matches the original routing path, end diameter, and clamp positions of the factory hose for a straightforward swap with no trimming or adapter fitting needed.
- Confirmed Fitment — Verified for DCA250SSI, DCA250SSIU, and DCA250SSI-3 ultra-silent diesel generator models.
- Sustained Charge-Air Efficiency — A properly sealed inter-cooler hose maintains charge-air pressure between the turbocharger and engine intake; a cracked or collapsed hose causes power loss, elevated exhaust temperatures, and poor load response.
- Fuel System Safety Relevance — Boost leaks caused by a degraded inter-cooler hose can force the engine to run over-fueled and over-temperature, increasing the risk of premature engine damage during extended generator operation.
The inter-cooler hose carries compressed, heat-soaked air from the turbocharger outlet to the intercooler, and then routes the cooled, denser charge air onward to the engine intake manifold. Keeping this path sealed and unobstructed is essential for the engine to produce its rated power output and maintain fuel efficiency under load. When the hose cracks, softens, or loses its clamp seal, boost pressure escapes, the engine loses power response, and the generator may struggle to hold voltage and frequency under heavy electrical loads.
