This coolant level sensor monitors the engine's coolant reservoir to ensure the proper fluid level is maintained, preventing overheating and potential engine damage. It sends real-time data to the vehicle's control unit, alerting the operator to low coolant conditions before they become critical, unlike a faulty sensor that might fail to detect a low level or trigger false alarms. Operators will typically see a 'Low Coolant' warning light or message on the instrument panel when the sensor detects a problem.
Always verify with serial number before ordering.

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing coolant level sensor may fail to alert the operator to a critically low coolant level, increasing the risk of engine overheating and severe damage. Conversely, it might trigger a false 'Low Coolant' warning, causing unnecessary concern and potential inspection delays. Persistent lack of warning for actual low coolant can lead to significant engine repair costs.
Ensure the engine is completely cool before attempting to remove the old sensor to avoid burns from residual hot coolant. Do not overtighten the new sensor, as this can crack the reservoir or damage the sensor threads.
When replacing the coolant level sensor, it is recommended to check the condition of the coolant hoses and the radiator cap.
