My car is an 11-year-old Global Hawk Liberty. Now there is a problem. The water in the water tank seems to be no longer circulating.

The thermostat is broken. This is a valve that controls the water cooling cycle of the car. The valve that connects the water tank and engine water circulation.

If it is blocked, the car water circulation will only open a small cycle.

If it is winter, it is quite normal for it to be very cold over there and the circulation is not open. If you don’t turn on the pot, there’s no problem
