1987 toyota pickup water temp gauge won't work

Why my 1987 toyota pickup water temp gauge won't work ? This is usually a problem with the water temperature sensor. Because of its three-wire water temperature sensor, one of its lines is the five signal voltages given to it by the water supply thermometer. You should check it first. Normally , it is a signal voltage of 5 volts . If the signal voltage is appropriate , the water temperature sensor itself is not a problem. That is the problem with the water temperature meter itself . Check whether the three line voltages of the 1987 Toyota Pickup water temperature sensor are appropriate ? You can also heat the water temperature sensor itself and see whether its resistance value drops or rises . Check the 1987 toyota pickup water temp gauge sensor itself. Soak the water temperature sensor in hot water and heat it. This sensor is a negative temperature sensor . The higher the temperature , the lower the resistance. Check whether it is suitable .

When the 1987 Toyota Pickup was just started, the water temperature was generally very low, especially in winter . At this time, the hot car should be carried out first. The hot car after starting the vehicle depends on whether the water temperature is normal . Generally , when the 1987 toyota pickup water temperature gauge reaches the middle position , the hot train is completed . Now you can drive according to your driving habits . Before that , drive slowly . Do not turn on the air conditioner if the water temperature does not reach the normal temperature. Otherwise , it will damage the engine and increase fuel consumption .

The water temperature is very important when driving 1987 toyota pickup , but strictly speaking, the water temperature displayed by our water thermometer is not the so-called water temperature . You can think that we have no chance to add water to the 1987 toyota pickup if we operate according to the regulations . The water inlet of the wiper should be filled with wiper agent, and the antifreeze inlet should be filled with antifreeze . Therefore , the water temperature on 1987 toyota pickup now shows the temperature of antifreeze . The water temperature actually refers to the temperature of antifreeze. In addition to oil pipes , the engine is also covered with antifreeze water channels.
