The Genie T113760GT is a genuine OEM Isuzu 4LE2 Thermostat designed for Genie AL-series light towers, including the AL5000, AL5, AL5 with Vertical Mast, and AL5HT. Sourced directly from the OEM supply chain, this thermostat matches the original component specification for a direct, confidence-inspiring installation. Cross-reference T113760GT against your parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Engine Calibration Match — Built to the exact thermal rating of the original Isuzu 4LE2 engine thermostat, ensuring the cooling system opens and closes at the correct temperature threshold.
- Direct Drop-In Installation — This thermostat seats into the factory housing with no modification to coolant lines, housing, or gasket surfaces required.
- Broad AL-Series Compatibility — Fits Genie AL5000, AL5, AL5 with Vertical Mast, and AL5HT light towers powered by the Isuzu 4LE2 engine.
- Engine Temperature Stability — A properly functioning thermostat keeps the Isuzu 4LE2 operating within its optimal temperature range, protecting the engine from overheating or running excessively cold during extended jobsite use.
- Engine Protection Under Load — Light towers often run for long, unattended overnight cycles; a failed or stuck thermostat can allow thermal runaway or cold-running rich fuel conditions — replacing this component promptly protects the engine investment.
The thermostat is a temperature-sensitive valve in the engine's cooling circuit. When the engine is cold, it stays closed, routing coolant only through the engine block to help it reach operating temperature quickly. Once the engine warms to the correct threshold, the thermostat opens and allows coolant to flow through the radiator, shedding heat and maintaining a stable temperature. A thermostat that sticks open causes the engine to run cold and burn fuel inefficiently; one that sticks closed can cause rapid overheating and serious engine damage. On a light tower like the AL5HT or AL5000 — units that frequently run overnight or in remote locations — keeping this component in good working order is essential to protecting the power plant and maintaining consistent output throughout the job.
