The Genie 123089GT Glow Plug is a genuine OEM component built for the GTH-636 telehandler. Sourced directly from Genie, this part meets the same standards as the original installed at the factory, ensuring correct fit and function for your machine. Cross-reference part number 123089GT against your GTH-636 parts manual to confirm this is the right plug for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's exact material and dimensional specifications, delivering the same fit and thermal performance as the original part.
- Direct Replacement — Designed to install in the same location as the original, with no modification to the engine or surrounding components.
- GTH-636 Fitment — Confirmed for the Genie GTH-636 telehandler; always cross-reference your serial number and parts manual before ordering.
- Cold-Start Reliability — A correctly functioning glow plug brings the combustion chamber to the temperature needed for a clean start in cold conditions; a failed one leads to hard starts, misfires, and unburned fuel.
- Operational Safety — Consistent engine starting performance is essential on a telehandler operating in demanding site conditions; a faulty glow plug can leave the machine unable to start when needed.
A glow plug is a pencil-shaped heating element threaded into each pre-combustion or combustion chamber of a diesel engine. When the ignition is switched to the preheat position, the plug heats rapidly to raise the air temperature in the chamber high enough for diesel fuel to ignite reliably — particularly important in cold ambient conditions. A worn or failed glow plug causes slow cranking, white smoke on startup, and rough running until the engine reaches operating temperature. Replacing a faulty plug restores clean cold-start performance and protects the engine from the stress of repeated unsuccessful start attempts.
