The Multiquip M1311600004 Radiateur Bouchon is a genuine OEM radiator cap designed for DCA45USI series ultra-silent diesel generators. As a direct OEM component, it meets the exact pressure and sealing specifications required to maintain proper coolant system operation in these units. This part is confirmed for DCA45USI, DCA45USI2, and DCA45USI4CAN models, including Canadian-market variants. Sourced directly through Multiquip's OEM supply chain, the part ensures your generator's cooling system performs exactly as engineered.
Key Features
- OEM-Specified Pressure Rating — Built to the exact pressure threshold required by the DCA45USI cooling system, ensuring proper coolant pressurization and boil-over protection.
- Direct-Fit Replacement — Designed to seat and seal on the OEM radiator filler neck with no modification to the housing or surrounding components.
- Confirmed Fitment — Compatible with DCA45USI, DCA45USI2, and DCA45USI4CAN ultra-silent diesel generator models.
- Cooling System Integrity — A correctly functioning radiator cap maintains the closed-loop pressure needed to prevent coolant loss and protect the engine from overheating during extended generator operation.
- Genuine OEM Component — Sourced directly from Multiquip, matching the original part specification for material grade and valve performance — not a generic cap adapted to fit.
The radiator cap performs a critical pressure-regulating role in the generator's liquid cooling system. It seals the coolant reservoir, maintains the system at the correct operating pressure to raise the coolant's boiling point, and releases excess pressure through a spring-loaded valve when a safe threshold is exceeded. A worn or failed cap causes coolant to escape, pressure to drop, and the engine to run hotter than designed — leading to overheating faults, unplanned shutdowns, and potential engine damage during long-duration power generation cycles.
