water temp gauge 1995 f150

During normal driving, pay attention to whether the pointer on the engine cooling water temperature gauge on the dashboard is normal. Other factors such as engine cooling fan failure that causes an increase in engine cooling water temperature or leakage in the cooling system piping may also cause a decrease in cooling water. Before adding distilled water , please note whether the amount and cycle of cooling water reduction are normal .

The temperature displayed on the vehicle instrument refers to the temperature of the cooling water. This instrument is called a water temperature gauge, and its unit is Celsius or Fahrenheit . Customers can choose their own according to their own needs. The cooling water for the vehicle engine uses special coolant . The sensor of the water temperature gauge is a variety of thermistor type sensors that are screwed onto the engine cooling water channel . The thermistor determines the amount of current flowing through the coil winding of the water temperature meter, thereby driving the pointer of the meter to swing .

The water temperature sensor is located under the shift lever, just find the engine water supply pipe, and there is a hemispherical water pipe joint between them. The thermostat is installed inside. If 1995 f150 is equipped with a B-series engine, the thermostat is located where the water supply pipe connects to the engine. Strictly speaking, water temperature sensors are divided into two categories. Regardless of its internal structure, it is a thermistor, with a resistance value between 275 ohms and 6500 ohms. Moreover, the lower the temperature, the higher the resistance value, and the higher the temperature, the lower the resistance value. The function of the water temperature sensor is relatively simple, which is to change the internal resistance value of the sensor to drive the change of the water temperature meter by changing the current flowing through the sensor to indirectly tell people the operating temperature of the engine. There is a water temperature gauge to see the specific water temperature. You can know the coolant condition in more detail. Generally, when the ratio of antifreeze to water is 40:60, the boiling point of the coolant is 106 ℃, and the freezing point is - 26 ℃. When 50:50, the boiling point of the coolant is 108 ℃, and the freezing point is - 38 ℃.
