Product Description
GM121803 Superseded from GM78797
Kohler (Rehlko) Low Coolant Level Sensor GM121803
The Kohler (Rehlko) Low Coolant Level Sensor GM121803 is a replacement coolant monitoring component for compatible Kohler liquid-cooled generator systems.
Low coolant level sensors detect when engine coolant drops below a designated level. Depending on the generator's control system, the sensor may signal a low coolant warning, fault indication, or protective engine shutdown.
Maintaining the correct coolant level is essential for proper engine temperature regulation. Insufficient coolant can reduce cooling system performance and increase the risk of overheating and engine damage.
A malfunctioning low coolant level sensor may cause inaccurate coolant level indications or interfere with the generator's coolant monitoring functions.
