What if the car thermometer is broken?

The water temperature light of the automobile instrument is always on, indicating that there is something wrong with the engine cooling system. Common fault points are: 1, the antifreeze in the engine cooling system is missing, and the engine may have leakage points, such as water pump leakage, pipeline damage and water tank damage.

2. The thermostat in the engine cooling system is out of order, resulting in high water temperature. Because the thermostat can't be opened, the flow of coolant in the engine is blocked, so the coolant temperature is too high;

3. The cooling fan in the engine cooling system is not working properly, resulting in poor cooling of the coolant. Therefore, the water temperature light is on, causing the coolant temperature to be too high;

4. The water pump of the engine cooling system fails, and the pump does not rotate smoothly, resulting in poor coolant flow, water temperature light on, and high coolant temperature.
