The Multiquip M2310502003 Upper Radiator Hose is a genuine OEM component designed for DCA70SSIU2 and MQP56 series diesel-powered generators. As an authorized Multiquip OEM part, M2310502003 is manufactured to the same specifications as the original, ensuring a direct, trouble-free installation with no modifications to existing fittings or coolant routing. Sourced through DHS Equipment, this hose is the correct replacement for keeping your generator's cooling system operating as intended.
Key Features
- Genuine OEM Construction — Produced to original hose routing specifications, including correct inner diameter, wall thickness, and reinforced bend geometry for this cooling circuit.
- Direct-Fit Installation — Molded to match the original upper coolant path, connecting the engine outlet to the radiator inlet with existing OEM clamps and no rerouting required.
- Confirmed Generator Fitment — Verified for DCA70SSIU2 ultra-silent generators and MQP56 standby generator models.
- Coolant Flow Integrity — Maintains full, unrestricted coolant circulation between the engine and radiator, which is critical for sustained load performance in continuous-duty generator applications.
- Pressure and Temperature Rated — Built from OEM-grade reinforced rubber compound to handle the elevated coolant temperatures and system pressures typical of diesel generator operation under load.
The upper radiator hose carries hot coolant from the engine's thermostat housing to the top of the radiator, where heat is dissipated before the cooled fluid returns to the engine. In a diesel generator running under sustained electrical load, this hose is under constant thermal and pressure cycling — a crack, soft spot, or failed seal causes coolant loss, rapid overheating, and potential engine shutdown. Replacing a worn or damaged hose with the correct OEM part restores full cooling capacity and prevents temperature-related faults.
