The Multiquip RE531244 Surge Tank is a genuine OEM component designed for the DCA70SSJU4i ultra-silent diesel generator. As an authorized Multiquip replacement part, it is manufactured to the exact specifications of the original, ensuring it integrates correctly with the cooling system on DCA70SSJU4i units. When your generator's surge tank cracks, leaks, or fails to maintain system pressure, this direct OEM replacement restores proper coolant system operation and keeps your generator running at its full rated output.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for the cooling system on ultra-silent diesel generator units, not a generic approximation.
- Direct-Fit Replacement — Engineered to mount and connect exactly as the original surge tank on the DCA70SSJU4i, using existing brackets and coolant lines without modification.
- Confirmed Fitment — Verified for the Multiquip DCA70SSJU4i ultra-silent generator series.
- Coolant Pressure Integrity — Maintains correct pressurization of the cooling circuit, preventing overheating and protecting the diesel engine from thermal damage during extended generator operation.
- Leak-Resistant Durability — Built to withstand the thermal cycling and pressure fluctuations common in continuous-duty generator applications, resisting cracking and coolant loss over time.
The surge tank — also known as a coolant overflow or expansion tank — serves as a pressure buffer and fluid reservoir within the engine's cooling circuit. As coolant heats up and expands during operation, the surge tank absorbs that volume and releases it back into the system as the engine cools, keeping the circuit properly filled and pressurized at all times. A cracked or failing surge tank can cause coolant loss, erratic system pressure, and ultimately engine overheating, making timely replacement critical for continuous-duty generator operation.
