The sensor body is made of brass, which is corrosion-resistant and high-temperature resistant. It works stably in the coolant environment, ensuring accurate temperature signal transmission without delay errors.
It adopts NPT1/2 standard thread for high compatibility, which can directly replace the original part without additional modification or wiring changes, making installation quick and easy.
It is mainly used to monitor the engine coolant temperature, providing temperature signals to the engine ECU to control fuel injection quantity and ignition timing, and also providing water temperature display signals to the instrument panel to prevent engine overheating faults.
Please check the thread specification, pin type and vehicle/engine model before installation to ensure compatibility. Apply thread sealant during installation to prevent coolant leakage.
