The Multiquip M3310503303 Inner Cooler Hose is a genuine OEM component designed for DCA150SSI and DCA150SSIU ultra-silent diesel generator models. As a factory-sourced part, it meets the original design and material specifications for these units, ensuring a correct, trouble-free installation.

Key Features
- OEM-Grade Hose Material — Constructed to the original compound and wall-thickness specification, maintaining the correct pressure handling and heat resistance required in a diesel generator cooling circuit.
- Exact Routing and End Dimensions — Matches the original hose geometry so it routes and seats correctly without trimming, stretching, or adapter fittings.
- Confirmed Fitment for DCA150SSI and DCA150SSIU — Verified for both the standard and ultra-silent variants of the DCA150SS series generator.
- Supports Consistent Coolant Flow — A correctly sized inner cooler hose maintains proper coolant circulation through the charge-air cooling path, preventing heat buildup that can derate generator output or trigger thermal shutdowns.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part number M3310503303, so you know it is the right component from the right source.
The inner cooler hose routes coolant or charge air between the engine's intercooler or aftercooler and associated components within the generator's thermal management system. It plays a direct role in keeping intake air temperatures within the designed operating range, which protects engine efficiency and output stability. When this hose deteriorates, cracks, or develops a leak, coolant or boosted air escapes the circuit, causing the engine to run hotter or lose power — making prompt replacement essential to keeping the generator performing at its rated capacity.
