The Multiquip 0845031303 is a genuine OEM Reserve Tank designed for DCA-series super-silent and ultra-silent diesel generators, including the DCA36SPXU4F, DCA45SSIU4F, DCA70SSIU4F, DCA56SPX, DCA40SSI, DCA40SSAI, DCA60SSAI, DCA60SSI2, and DCA45SSIU4FC8 models. As a direct Multiquip OEM part, the part is manufactured to the same specifications as the original component installed at the factory, ensuring a drop-in fit with no modifications to existing plumbing or mounting points. This part is confirmed compatible across both 50Hz and 60Hz variants within the DCA super-silent generator family, making it the correct choice for fleet operators and service technicians working across multiple units.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design spec, with matching tank capacity, port sizing, and mounting geometry for the DCA generator series.
- Broad DCA Series Compatibility — Fits DCA36SPXU4F, DCA45SSIU4F, DCA70SSIU4F, DCA56SPX, DCA40SSI, DCA40SSAI, DCA60SSAI, DCA60SSI2, DCA45SSIU4FC8, and associated 60Hz variants.
- Direct Fit Replacement — Mounts to the original reservoir bracket and connects to existing coolant or fluid lines without rework, keeping service time to a minimum.
- Protects Cooling System Integrity — A properly functioning reserve tank maintains correct fluid volume in the cooling circuit, preventing air ingestion and thermal instability during extended generator runs.
- Built for Continuous-Duty Generator Service — Engineered to withstand the heat cycles and vibration loads inherent to diesel generator operation in demanding construction and rental fleet environments.
A reserve tank serves as the overflow and replenishment reservoir for the engine's cooling system. As coolant heats up and expands during operation, excess fluid is directed into the reserve tank; when the system cools and contracts, that fluid is drawn back into the radiator to maintain the correct fill level. A cracked, leaking, or failed reserve tank causes the cooling system to lose fluid over time, leading to low coolant levels, elevated operating temperatures, and potential engine damage during long generator run cycles. Replacing a damaged tank promptly with the correct OEM part restores the closed-loop cooling system to proper function and protects the generator's diesel engine from heat-related wear.
