The Multiquip V1674922 Filler Expansion Tank Cap is a genuine OEM component designed for the DCA400SSV diesel-powered generator series. As a direct OEM replacement, it is manufactured to the exact tolerances and pressure specifications required by the original equipment, ensuring the cooling system performs exactly as engineered. DHS Equipment supplies this part backed by Multiquip's OEM sourcing, so you can be confident you are receiving the correct cap for your machine. Verify your model code against DCA400SSV when ordering to confirm fitment.
Key Features
- OEM Pressure Rating: — Built to the exact pressure specification of the original cap, maintaining proper coolant system pressurization in the DCA400SSV cooling circuit.
- Direct Seal Fit: — Engineered to seat flush on the expansion tank filler neck, delivering a leak-free seal without any modification to the tank or mounting surface.
- DCA400SSV Compatibility: — Confirmed fitment for the DCA400SSV ultra-silent diesel generator series, eliminating guesswork when sourcing a replacement.
- Coolant System Integrity: — A functioning expansion tank cap regulates system pressure and prevents coolant loss; a worn or faulty cap can cause overheating and unplanned generator shutdowns.
- Genuine OEM Part: — Sourced directly through Multiquip's OEM supply chain, ensuring material grade and cap valve performance match the original component specification.
The filler expansion tank cap seals the coolant expansion tank and maintains the correct pressurized environment within the engine cooling system. By holding a calibrated release pressure, it allows coolant to expand safely into the tank during operation and return to the radiator as the engine cools — a cycle that protects against overheating and coolant loss. When this cap wears out, loses its seal, or fails to hold pressure, the cooling system can become compromised, leading to elevated engine temperatures and potential damage to the generator's diesel powerplant.
