What does it mean that the water temperature indicator on the dashboard of the car is always green?

The water temperature indicator on the dashboard of the car is always green, indicating that the temperature is too high.

When the car is driving, the water temperature in the water tank reaches 100 degrees, and then the water temperature indicator light will light up, which is commonly known as "boiling". You should pull over when the water temperature indicator of the vehicle is on. Don't turn off the engine in a hurry at this time. Excessive water temperature will affect engine cooling, engine components will overheat and expand, and the engine will be damaged after flameout.

Water thermometer sensor: It is a thermistor sensor. Screw on the engine cooling water channel. Thermistor determines the current flowing through the coil winding of water thermometer. So as to drive the instrument pointer to swing. In the past, the cooling water of automobile engines was used as tap water. Nowadays, many automobile engine cooling systems use special coolants. Therefore, it is also called coolant thermometer.

The correct way to extend the data temperature indicator is to keep the car idling and wait for it to cool down. When the water temperature is completely cooled, you must also find time to go to the repair shop for inspection after adding cold water again, because the cause of "boiling" is not only the heavy workload of hot air conditioning, but also the problems of fans, thermostats or pumps.

Some people say that the engine can be cooled by pouring cold water. Actually, this is not right. We all know that when it is hot, it will expand and contract. It is easy to burst the engine block when it is hot.

Others said that you can try to screw a small crack in the water tank to let the water vapor out. In fact, I suggest that if you are not in a hurry, you can wait for a while, because there is a lot of pressure inside the water tank when you "boil". If it is not screwed properly, it will cause the high-temperature coolant in the water tank to spray out, causing burns on the hands and even the face.
