This part is a coolant temperature sensor that monitors the engine's coolant temperature and transmits this data to the engine control unit (ECU). It is manufactured to meet stringent OEM quality standards, providing accurate readings unlike a faulty sensor which may send incorrect temperature signals. Operators may observe erratic temperature gauge readings, engine overheating warnings, or the engine entering a reduced power mode when this sensor fails.
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.
The initial symptom of a failing coolant temperature sensor is often an inaccurate reading on the temperature gauge, showing either too cold or too hot. If left unaddressed, this can lead to the engine running inefficiently or experiencing damaging overheating. The worst consequence is potential engine damage due to prolonged operation outside optimal temperature parameters.
Ensure the engine is completely cool before draining coolant and removing the old sensor. Overtightening the new sensor can damage its threads or the engine block.
Inspect the radiator, hoses, and water pump for leaks or wear when replacing the coolant temperature sensor.
