What happened to the high water temperature of Volkswagen Polo 1.4 displacement water tank?

Whether the antifreeze/coolant level is normal, if the coolant level is low, the water temperature will be high. Open the hood, the car won't open. First, observe the water thermometer to see if the temperature will become very high soon. Secondly, let's see if the electronic fan starts automatically when the water temperature is high. The car itself will have a rotating fan to cool the car, and then there will be one or two electronic fans in front to speed up the cooling. If the temperature is high and the electronic fan does not start, it means that the sensor started by the electronic fan is broken and the temperature cannot be measured, so it is not started. It doesn't cost much to change a sensor. It's simple.

If the electronic fan rotates and the water temperature still rises, it is likely that there is less coolant. You can try to turn on the warm air to see if there is any heat. If it is the hottest but not warm at all, it means there is too little coolant.

Don't drive when the water temperature is too high, it will burn out the engine. If the water temperature is high on the road, you can use warm air to cool the car. At the same time, by increasing the speed, the car can be air-cooled, the circulation of the coolant inside can be accelerated, and the heat dissipation will be much better.

Look at it!
