The Multiquip M2310502203 Upper Radiator Hose is a genuine OEM component designed for DCA70USI2 and DCA70USI3CAN ultra-silent diesel generators. As a direct factory replacement, this hose is manufactured to the exact dimensions and material specifications required by these machines, ensuring a correct, leak-free connection between the engine and radiator. Sourced directly from Multiquip, part number M2310502203 is the same hose installed during original production — no guesswork on fit or compatibility.
Key Features
- OEM-Grade Coolant Integrity — Manufactured to exact wall thickness and pressure tolerance specifications for high-temperature diesel generator cooling systems, preventing premature cracking or collapse under sustained load.
- Direct Upper-Port Connection — Engineered to seat correctly on the upper radiator inlet and engine outlet ports of DCA70USI2 and DCA70USI3CAN generators, eliminating the need for adapters or modifications.
- Confirmed Generator Fitment — Verified for DCA70USI2 and DCA70USI3CAN ultra-silent diesel generator models.
- Sustained Cooling Performance — A properly seated upper radiator hose maintains consistent coolant flow to the radiator, preventing overheating during extended generator run cycles. A cracked or swollen hose can cause rapid coolant loss and engine shutdown.
- Fuel System Compatibility Assurance — Built from materials rated for diesel generator operating temperatures, resisting the heat cycling and vibration common in continuous-duty generator environments.
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 coolant recirculates back through the engine. It is one of the most thermally stressed hoses in the cooling circuit, exposed to repeated expansion and contraction with every run cycle. When this hose softens, cracks, or loses its seal, coolant escapes rapidly — leading to overheating, potential engine damage, and unplanned generator downtime on the job.
