The Multiquip M5311500203 is a genuine OEM Inter-Cooler Hose designed for the DCA250SSI, DCA250SSIU, and DCA250SSI-3 ultra-silent diesel generator series. As a direct OEM replacement, the M5311500203 matches the original routing, diameter, and material specifications of the factory-installed hose, ensuring a correct, leak-free connection in the charge air circuit. Sourced directly through Multiquip's authorized parts network, this hose is the recommended service replacement for any DCA250SSI-series generator requiring inter-cooler hose repair or preventive maintenance.
Key Features
- OEM-Grade Reinforced Construction — Built to withstand the elevated pressures and temperatures present in a turbocharged diesel charge air circuit, matching the material durability of the original factory hose.
- Exact-Fit Routing and Dimensions — Replicates the original hose profile for the DCA250SSI series, connecting securely to existing clamp positions without rework or trimming.
- Confirmed Fitment for DCA250SSI Series — Verified for DCA250SSI, DCA250SSIU, and DCA250SSI-3 ultra-silent diesel generator models.
- Maintains Charge Air Efficiency — A properly sealed inter-cooler hose keeps cooled, compressed air flowing to the engine at the correct pressure, preserving fuel efficiency and power output across the generator's load range.
- Fuel System and Emissions Integrity — A failing or cracked inter-cooler hose can cause boost pressure loss, increased exhaust temperatures, and potential compliance issues on emission-rated diesel equipment — replacing with a genuine OEM part restores proper system operation.
The inter-cooler hose connects the turbocharger or charge air cooler to the engine's intake manifold, carrying compressed air that has been cooled to improve combustion efficiency. By reducing the temperature of the intake charge, the inter-cooler system allows the diesel engine to run at higher output levels without thermal stress. When this hose cracks, collapses, or loses its seal, boost pressure drops, the engine loses power, runs hotter than normal, and fuel consumption increases — making timely replacement critical to keeping the generator performing at rated capacity.
