Key Features

• Genuine OEM Construction — Molded to the original 5.0 L capacity specification, ensuring correct fluid volume and proper coolant system pressure balance for your generator.
• Drop-In Fitment — Mounts to the original bracket and connects to the existing overflow hose routing without modification, restoring the cooling circuit exactly as designed.
• Broad DCA and NGA Generator Compatibility — Verified for DCA125, DCA180, DCA220, DCA250, DCA300, DCA400, NGA100, and NGA150 series ultra-silent and super-silent generator models.
• Cooling System Integrity — A properly functioning reserve tank maintains stable coolant levels during heat cycling, preventing air ingestion into the cooling circuit and protecting the engine from overheating.
• Authentic Multiquip Part — Part 0802081003C is sourced directly through authorized Multiquip distribution channels, so you receive the correct component the first time.

The coolant 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 routed into this tank; when the engine cools down, that fluid is drawn back into the radiator to maintain a full system. Without a functioning reserve tank, the cooling circuit cannot self-regulate coolant volume correctly, which can lead to air pockets in the system, unstable operating temperatures, and accelerated wear on the engine. On generator sets like the DCA and NGA series — which are often run for extended periods under sustained load — keeping the coolant circuit fully sealed and properly filled is critical to continuous, uninterrupted operation.
