The Multiquip M0311500203 Upper Radiator Hose is a genuine OEM replacement designed for DCA10SPXU4 and DCA15SPXU4F series ultra-silent diesel generators. As an authorized Multiquip OEM part, M0311500203 is manufactured to the exact material composition, diameter, and bend geometry required for proper coolant flow in these units. Sourced directly through Multiquip, this hose delivers a straight-swap installation with no trimming or adaptation needed. If your generator is showing signs of coolant leaks, overheating, or a collapsed hose, this is the correct OEM replacement to restore proper cooling system function.
Key Features
- OEM-Grade Hose Construction — Manufactured to Multiquip's exact material and wall-thickness specifications, ensuring proper pressure retention and heat resistance throughout the cooling circuit.
- Exact-Fit Routing and Geometry — Molded to match the factory hose path between the engine and radiator, so the hose seats correctly on both connection points without stress or misalignment.
- Confirmed Fitment — Verified for DCA10SPXU4 and DCA15SPXU4F ultra-silent diesel generator models.
- Cooling System Integrity — A properly functioning upper radiator hose maintains consistent coolant flow to the radiator; a cracked, collapsed, or leaking hose leads to overheating and potential engine damage during operation.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, ensuring correct part number traceability and compatibility with the original cooling system design.
The upper radiator hose carries hot coolant from the engine's outlet port to the top of the radiator, where heat is dissipated before the coolant is recirculated back through the engine. In diesel-powered generators like the DCA10SPXU4 and DCA15SPXU4F, maintaining a sealed and unobstructed cooling loop is critical to sustained output and engine longevity. When the upper hose deteriorates — through cracking, softening, or collar wear — coolant loss and engine overheating follow quickly, taking the generator offline and risking more serious internal damage.
