ford 8n water temp gauge dash location

• 2023-03-09

The Ford 8n water temp gauge dash location is on the left of the fuel gauge on the instrument panel. The water temperature gauge shows the coolant temperature, which is convenient for the owner to understand the vehicle condition. When the water temperature of the car is too high, the owner should stop and rest, wait for the water temperature of the car to drop to the normal temperature, and then continue driving.

When checking the Ford 8n water temp gauge sensor and water temperature indicator, remove the wiring on the sensor and measure the resistance between the sensor input terminal and the ground. If the resistance of thermistor is 100 at room temperature ω Left or right indicates that the sensor is in good condition; Another resistance value is 80-100 ω The resistance of the water temperature indicator is directly grounded instead of the sensor. When the power is turned on, if the needle of the water temperature indicator is between the spring gap and the false hook of 60-70, it indicates that the water temperature indicator is in good condition. The lower the temperature, the lower the water temperature, and the longer the time from heating up to turning off the light. You can start after half a minute of ignition, but the speed and speed should not be too high before the water temperature light goes out. But you don't need to pay attention to this green light, it is definitely not the problem of low water temperature. According to the situation, it should be the problem of the water temperature sensor. Normally, after the engine has been used for a long time, the water temperature is only getting higher and higher due to the accumulated scale of the coolant in the engine and the blockage of the dust on the radiator radiator radiator. However, the red light is on. No matter whether the water temperature is high or not, it needs to be repaired.

When the water temperature is low, the resistance of the thermistor in the sensor is large, and the current flowing through the coil l1 and l2 is not much different. However, due to the large number of turns in l1, the magnetic field generated is strong, and the armature 3 with the pointer will deflect to the left, making the pointer point to the low temperature scale; When the water temperature increases, the thermistor resistance decreases, the shunt effect increases, the current flowing through l1 decreases, the magnetic force decreases, the armature deflects to the right, and the watch needle points to the high temperature scale.
