water temp gauge won't go up

• 2022-07-09

During the operation of the engine, the temperature will not be too low, so the temperature of the water circulation system of the engine is not the lower the better, but the normal working state is within a certain temperature range. When the car is running normally, the temperature of the antifreeze will rise with the temperature of the car engine, but after the pointer of the water temperature gauge reaches 90 ℃, because of the heat exchange balance, the temperature of the antifreeze will not rise again. Therefore, the best working condition of the engine is that the temperature reaches the central position of 90 ℃.

And for cars, the water temperature does not need to be excessively prevented, because the car will not have too high a water temperature after a long time of driving. Therefore, with the water temperature lamp, the water temperature gauge is too chicken ribs. But if you want to keep your car away from the high water temperature, you only need to check the use of antifreeze regularly in high-temperature weather,because the external temperature is high, the car will also be affected with the temperature rise, especially in the process of driving, the water temperature will be slightly higher, and if there is too little antifreeze, there may be a high temperature prompt.

The function of the water temp gauge is to show the working temperature of the coolant in the water jacket of the engine cylinder head. The water temperature warning lamp can light up when the coolant temperature rises to close to the boiling point (such as 95 ~ 98 ℃), so as to attract the attention of the driver.

If the car water temp gauge won't go up, first check whether the wire head is broken and loose. If ok, the water temperature sensor instrument is broken. You can unplug the water temperature sensor and put the plug on the wire. Open the key and look at the thermometer on the instrument every time you turn. If the water temperature sensor is broken, do not replace the instrument. The power line of the water temperature gauge is disconnected, the electric heating coil of the water temperature gauge is burnt out, and the electric heating coil of the water temperature gauge sensor is burnt out or has poor contact.
