Key Features
- Genuine OEM Quality — Manufactured to Genie's original specifications, ensuring correct electrical characteristics and dimensional conformity for a direct swap.
- Direct-Fit Replacement — Designed to connect and install in the same position as the original switch, with no rework or adaptation needed.
- Broad GTH Telehandler Coverage — Fits GTH-644, GTH-844, GTH-842, and GTH-636 models, covering a wide range of the Genie GTH telehandler lineup.
- Temperature Monitoring Integrity — A correctly functioning water temp switch triggers the appropriate warning or shutdown response when coolant temperature reaches a critical threshold, protecting the engine from heat-related damage.
- Operational Safety — Temperature monitoring is a key layer of engine protection on a telehandler. A failed or inaccurate switch can allow overheating to go undetected, putting both the machine and operator at risk.
A water temp switch monitors coolant temperature and signals the machine's warning or control system when a temperature threshold is reached. On telehandlers like the GTH series, this switch plays an important role in engine protection — when it triggers correctly, operators receive an early warning that allows them to shut down before serious damage occurs. A switch that fails to close, opens at the wrong threshold, or sticks can either mask a genuine overheat condition or cause unnecessary shutdowns, both of which impact productivity and machine health. Replacing a suspect switch with a genuine OEM part ensures the sensor responds accurately and as originally intended.
