The Multiquip M3310503603 Upper Radiator Hose is a genuine OEM component designed for DCA150SSI and DCA150SSIU ultra-silent diesel generators. As a direct OEM replacement, this hose meets the original design specifications for material grade, wall thickness, and end fitment — ensuring a proper seal against the cooling system connections on these generator models. Sourced directly through Multiquip's authorized parts channel, M3310503603 is the correct, no-guesswork choice for restoring cooling system integrity on your DCA150 series machine.
Key Features
- OEM-Grade Coolant Containment — Manufactured to the original hose material and pressure rating spec, maintaining a leak-free seal under sustained engine operating temperatures.
- Direct Upper-Circuit Fit — Engineered to connect the engine outlet port to the radiator inlet on DCA150SSI and DCA150SSIU units, seating correctly with existing clamps and fittings.
- DCA150 Series Compatibility — Confirmed fitment for DCA150SSI and DCA150SSIU ultra-silent diesel generator models.
- Cooling System Performance — A sound upper radiator hose keeps coolant flowing at the correct volume and pressure between the engine and radiator, preventing overheating that can cause generator derating or unplanned shutdown.
- Fuel System Separation Integrity — As a critical coolant-circuit component on a diesel-powered generator, maintaining hose condition prevents coolant loss that could compromise engine protection systems and trigger automatic safety shutoffs.
The upper radiator hose carries hot coolant from the engine's thermostat outlet to the top of the radiator, where heat is dissipated before the cooled fluid cycles back through the engine. On a diesel generator like the DCA150SSI series, this loop runs continuously under load, making the hose a high-wear component subject to heat cycling, pressure fluctuations, and rubber degradation over time. A cracked, collapsed, or leaking upper hose will cause rapid coolant loss, leading to engine overheating and automatic protective shutdown — making timely replacement essential to maintaining continuous power output.
