the Lord of Tools 1Pc M14x1.5 Water Temperature Sensor 12V Radiator Fan Switch On 90?(194F) Off 80?(176F) Engine Brass

Temperature sensors are installed at strategic locations near the radiator or engine to accurately monitor temperature. When the temperature reaches or exceeds 90°C, the sensor will send a signal to the control unit, and the control unit will start the radiator fan for heat dissipation. As the heat dissipates, the engine temperature begins to drop. When the temperature drops to 80°C or below, the sensor will send a signal to the control unit again, and the control unit will turn off the radiator fan to save energy and reduce noise. Please find out the ideal operating temperature of your vehicle first. The temperature must be suitable before you can use it. Do not use it under conditions that exceed the working range of the sensor to avoid damaging the sensor or affecting the performance of the car.
