The Multiquip M1311501003 is a genuine OEM Lower Intercooler Hose designed for DCA36SPXU4F and DCA45SSIU4F series super-silent diesel generators. As a factory-sourced component, it is built to exact material and dimensional tolerances required by Multiquip's Tier 4 ultra-silent generator lineup. This hose services the DCA45SSIU4FC8 and associated 60Hz variants, including fleet-spec configurations, making it the correct choice for owners and service teams running these units in the field. Sourcing part number M1311501003 directly ensures a precise match to the original component without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to the exact wall thickness, inner diameter, and heat-resistant compound specified for pressurized intercooler circuits on Multiquip diesel generators.
- Direct-Route Replacement — Follows the factory hose routing between the intercooler and charge-air ducting, connecting to OEM clamp positions without re-routing or adapter fittings.
- Confirmed Fitment — Verified for DCA36SPXU4F, DCA45SSIU4F, DCA45SSIU4FC8, and their 60Hz variants, including the DCA45SSIU4F 60Hz Aggreko fleet configuration.
- Charge-Air Integrity — Maintains a sealed, low-restriction path for compressed and cooled charge air, preserving engine output and fuel efficiency under continuous load operation.
- Designed for High-Cycle Thermal Demands — The hose material is rated to withstand the repeated heat and pressure cycles typical of Tier 4 diesel engines running at extended duty in sound-attenuated enclosures.
The lower intercooler hose carries charge air from the intercooler to the engine's intake manifold after it has been cooled from the turbocharger. On turbocharged diesel generators like the DCA36SPXU4F and DCA45SSIU4F, this cooling step is critical — cooler, denser air entering the engine means cleaner combustion, higher power output, and lower exhaust temperatures. When this hose cracks, collapses, or develops a leak, boost pressure is lost, the engine loses power, runs hotter, and may trigger fault codes or protective shutdowns. Replacing a degraded hose promptly with the correct OEM part restores proper airflow and protects the engine from the compounding effects of running in a hot, boost-starved condition.
