The Genie 1266790GT is a genuine OEM Kohler Thermostat designed for the RL4 Vertical Mast light tower. Sourced directly from Genie, this part meets the exact specifications required by the original engine manufacturer, ensuring proper fit and correct calibration within the Kohler engine's cooling circuit. Whether you're performing scheduled engine maintenance or replacing a failed component, this thermostat is the correct OEM solution for the RL4. Cross-reference part number 1266790GT against your parts manual to confirm fitment before ordering.
Key Features
- OEM-Calibrated Temperature Rating — Engineered to open and close at the precise temperature threshold specified for the Kohler engine, keeping the cooling system operating within its designed range.
- Direct-Fit Replacement — Built to match the original thermostat's housing dimensions and seating profile, dropping into the engine's cooling circuit without modification.
- Confirmed Fitment for the RL4 — Verified as the correct replacement thermostat for the RL4 Vertical Mast light tower equipped with a Kohler engine.
- Protects Against Overheating — A thermostat that sticks open runs the engine cold and reduces efficiency; one that sticks closed causes overheating. This genuine OEM part restores correct thermal regulation and protects engine components from heat-related wear.
- Engine Longevity — Consistent coolant temperature control reduces thermal cycling stress on gaskets, seals, and internal engine components, extending service intervals and overall engine life.
The thermostat is a small but critical component in any liquid-cooled engine's cooling system. It sits in the coolant circuit and controls the flow of coolant to the radiator based on engine temperature — remaining closed when the engine is cold to allow it to warm up quickly, then opening once the operating temperature is reached to allow coolant to circulate and dissipate heat. On the RL4 light tower, a faulty thermostat can cause the Kohler engine to run too hot or too cold, leading to reduced efficiency, accelerated wear, or engine shutdown. Replacing a failed thermostat promptly with the correct OEM part keeps the engine's thermal management working exactly as designed.
