This part is a temperature sensor plug, essential for monitoring and regulating the engine's coolant temperature within the specified operating range. It ensures accurate readings are sent to the engine control unit (ECU), preventing overheating or undercooling issues. A failing plug may exhibit corrosion or physical damage, leading to inaccurate temperature readings or complete signal loss, which an operator might notice as erratic temperature gauge behavior or engine warning lights.
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.
An inaccurate temperature reading on the dashboard gauge is often the first sign of a faulty sensor plug. If left unaddressed, this can lead to the engine operating outside its optimal temperature range, potentially causing increased wear. Continued operation with a malfunctioning sensor plug risks engine damage due to overheating or inefficient performance.
Ensure the engine is completely cool before attempting removal to avoid burns and coolant spillage. Do not overtighten the new plug, as this can damage the threads in the engine block or cylinder head.
When replacing the temperature sensor plug, it is advisable to inspect the thermostat and radiator cap for proper operation.
