1992 ford 4.9l water temp gauge circuit

• 2023-05-18

It is normal for the pointer to 1992 ford 4.9l water temp gauge reach 90 degrees. Generally, driving for about 5-10 minutes will cause the water tempgauge to become too high (with an indicator light warning), which can cause the water tank to boil and cause engine malfunction. If the water temperature is too high or rises too fast, the vehicle should be stopped and stopped. After the vehicle's water tank cools down, add mineral water or tap water, and restart the vehicle if it is still abnormal. Contact roadside rescue. Attention: Due to high water temperature, it is easy to cause water tank spraying. Do not immediately open the water tank cover. If it is urgent to open it, it is recommended to cover the water tank cover with a damp towel and unscrew it to the left. 

When the engine is working, If the pointer of the oil pressure gauge is The outer side of position 0 does not move, which is usually caused by a broken circuit in the wire from the ignition switch to the oil pressure gauge or the burning of the sensor or internal resistance coil of the oil pressure gauge. The red light is always on, and the engine is turned off before opening the ignition lock. The wire on the sensor terminal is removed, and the light is still on, indicating that there is a ground connection between the indicator light and the sensor. If the light is not on, it indicates that the light bulb is burnt out or the sensor is faulty. The installation direction of the sensor is correct, but To avoid direct radiation and heating of other components by the hot air flow of the bimetallic sheet inside the sensor. After 1992 ford 4.9l car water temp gauge circuit, the two terminals can be wired randomly, one connected to the ignition switch and the other connected to the sensor. Because the current in the circuit remains the same regardless of how it is connected, it does not affect its indicated value. 

The water tempgauge can be used to indicate whether the working temperature of the cooling water in the engine water pump is normal. It consists of two parts: a water temperature indicator installed on the dashboard and a water temperature sensor (commonly known as a sensing greenhouse) installed on the engine cylinder head water pump.
