The normal water temperature of a car is 90 degrees, usually between 70 and 90 degrees. The high water temperature is caused by insufficient cooling liquid, failure of cooling fan and failure of circulating water pump. Coolant leakage or insufficient coolant will cause the engine water temperature to rise. If it is not enough, add it to the appropriate position first.
Inside the automobile water temperature sensor is the automobile water temperature sensor. The lower the temperature, the greater the resistance and the smaller the resistance. It is installed on the water jacket of the engine cylinder block or cylinder head, which is in direct contact with the coolant and is used to measure the coolant temperature of the engine. The temperature sensor used in the coolant thermometer is negative temperature coefficient (NTC), whose resistance decreases with the increase of temperature, and a wire is connected to ECU. The other is the ground wire. Do you like it, Houthi? February 2022 17
