Key Features
- OEM Sealing Integrity — Manufactured to the exact dimensional spec for a consistent, pressure-retaining press fit in the bore it seals.
- Drop-In Installation — Engineered to seat directly into the original bore without machining or modification to the housing.
- Broad Equipment Coverage — Fits the DAW-500S welder and DCA15SPX3 and DCA10SPX3 diesel-powered generators in a single part number.
- Engine Coolant Path Protection — Maintains the integrity of the engine block's internal galleries, preventing fluid loss that can lead to overheating or pressure loss.
- Genuine Multiquip OEM Part — Supplied through the authorized Multiquip parts network, so you receive the correct component with no guesswork on fitment.
An expansion plug — sometimes called a core plug or freeze plug — seals the machined openings left in an engine block or housing during the casting process. It maintains the integrity of the engine's internal coolant passages, preventing leaks and keeping the cooling system pressurized and functional. When an expansion plug corrodes, loosens, or is displaced, coolant loss follows quickly, which can drive the engine toward overheating and serious internal damage if left unaddressed.
