Key Features
- Genuine OEM Kubota Engine Fit — Built to the original Kubota engine specification, ensuring correct electrical resistance and heat output for reliable cold-start performance.
- Direct Drop-In Replacement — Engineered to the same thread pitch, tip length, and connector type as the original, so installation is straightforward.
- Broad Genie Compatibility — Fits AL4, AL4000, AL5, AL5HT, AL5 with Vertical Mast, and RL4 light towers, as well as Z-34/22 Bi-Energy, Z-34/22 IC, and Z-34 IC articulating boom lifts.
- Cold-Start Reliability — A functioning glow plug pre-heats the combustion chamber so the engine fires promptly in cold or damp conditions; a failed plug leads to hard starts, rough running, or a no-start condition.
- Sourced from DHS Equipment — Supplied as a genuine Genie OEM part, so you receive the correct component backed by the manufacturer's part number 839119GT.
A glow plug is a small electric heating element threaded into the prechamber or combustion chamber of a diesel engine. When the engine is cold, the glow plug draws current from the battery and heats rapidly to raise combustion-chamber temperature high enough for the diesel fuel to ignite on cranking. Without sufficient heat, the engine struggles to start or may not fire at all, particularly in cool ambient temperatures common on early-morning or winter jobsites. A worn or burned-out glow plug causes extended cranking, white exhaust smoke on startup, and increased engine wear from repeated failed start attempts — replacing it promptly with the correct OEM part restores normal cold-start behavior and protects the engine.
