1997 ford ranger water temp gauge not moving

• 2022-07-09

If the 1997 ford ranger water temp gauge not moving , maybe the wire of the water temperature gauge sensor is improperly connected or disconnected . The voltage regulator that provides a stable power supply for the water temperature gauge circuit is damaged . Try it . The heater is hot . And the temperature of the upper tube and the lower tube is the same . It is recommended to check whether there is a thermostat . After confirming that there is no problem, consider the sensor, circuit and water temperature gauge . It should be that the thermostat is broken, the thermostat is always open, and the coolant is always in a large circulation state. Summer is better , but it is difficult to get water temperature in winter .

This situation may be due to the failure of the water temperature gauge used in the car . It is recommended to go to a professional car 4S shop for repair . If there is no problem , you can also manually adjust it within three degrees. If the water temperature gauge fails , the critical in the thermometer is damaged , and the service life of the water temperature gauge is too long. Check whether the line is loose and the engine has problems . It's likely that the water temperature gauge doesn't work because it has a problem and breaks down . It's also possible that there is a problem with the appearance of the manufacturer. It is recommended to replace a water temperature gauge . It's also possible that if the water temperature doesn't rise when I first start the car , it's because the engine is cooler , and it will get better slowly .

It is also possible that the water temperature cannot rise because the thermostat is not closed tightly , resulting in a large circulation of water , and the temperature is difficult to increase. It is recommended that the thermostat be replaced .

When the temperature of the coolant reaches the specified value (above 80 ℃), the paraffin begins to melt and gradually turns into liquid . The volume then increases and compresses the rubber tube to shrink . While the rubber tube shrinks , it acts an upward thrust on the push rod, which has a downward reverse thrust on the valve to open the valve.
