The Multiquip 8970736410 is a genuine OEM Glow Plug DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement, this glow plug is sourced from Multiquip's authorized parts supply chain, ensuring it meets the exact specification required by the 4LE2 engine installed in the DCA25USI. Keeping this component in proper working order is essential for reliable cold-start performance and consistent engine ignition. DHS Equipment stocks this part ready for order so you can get your generator back on the job without unnecessary delays.
Key Features
- OEM-Spec Heating Element — Engineered to deliver the correct pre-heat temperature required by the Isuzu 4LE2 engine, ensuring consistent combustion initiation across cold-start conditions.
- Direct Drop-In Installation — Threads directly into the cylinder head of the DCA25USI with no adaptation needed, matching the original plug's thread pitch, reach, and connector type.
- Confirmed DCA25USI Fitment — Specifically referenced to the DCA25USI ultra-silent diesel generator, so you can order with confidence knowing this is the correct part for your machine.
- Protects Cold-Start Reliability — A worn or failed glow plug causes hard starting, excessive cranking, and incomplete combustion; replacing it with the correct OEM part restores immediate engine response in cold or damp conditions.
- Fuel System Integrity — Proper glow plug function supports clean fuel ignition, reducing unburned fuel contamination in the combustion chamber and protecting downstream engine components over the long term.
A glow plug is an electrically heated element mounted in each cylinder of a diesel engine that pre-heats the combustion chamber before and during startup. Unlike gasoline engines, diesel engines rely on heat from compression to ignite fuel — but in cold conditions, the cylinder walls can absorb enough heat to prevent ignition. The glow plug compensates by raising the local temperature in the chamber so the engine fires cleanly on the first crank. When a glow plug fails or degrades, the engine may crank repeatedly without starting, produce white smoke on startup, or run roughly until it fully warms up. On a generator like the DCA25USI, where reliable startup is critical to powering sensitive equipment, maintaining a functional glow plug is a basic but essential part of the service schedule.
