Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original pressure and dimensional specification for the 6D16 engine block, ensuring a proper seal without leakage risk.
- Direct Drop-In Installation — Engineered to the same press-fit dimensions as the original, seating correctly into the DCA-85SSM engine block passages without reworking the bore.
- Confirmed DCA-85SSM Fitment — Specifically referenced for the DCA-85SSM ultra-silent generator series, eliminating compatibility uncertainty during service.
- Engine Block Protection — A correctly seated expansion plug keeps coolant passages sealed and engine block galleries pressurized, preventing coolant loss and potential overheating of the 6D16 engine.
- Critical Cooling System Safety — A failed or missing expansion plug can allow coolant to escape under pressure, leading to rapid engine temperature rise and serious engine damage; using the correct OEM plug maintains system integrity.
An expansion plug — sometimes called a freeze plug or core plug — seals the casting holes left in an engine block during the manufacturing process. In the 6D16 diesel engine fitted to the DCA-85SSM generator, these plugs also serve as pressure relief points within the cooling system. When an expansion plug corrodes, cracks, or is dislodged, coolant can escape from the block, causing the engine to overheat rapidly. Replacing a compromised plug promptly with the correct OEM component, Multiquip MF665508, restores full cooling system containment and protects the engine from heat-related damage.
