Carefully observe the leaking place of the water tank to see if there is dripping water on the ground. If there is, it means that the water leakage is serious; If not, there are two situations, 1 means that the water in the water tank has completely leaked, and the other is that the water in the water tank has entered. If the water leakage is serious, it is recommended not to start again. Call a repairman to deal with it. If there is no water in the water tank, it will pull the cylinder. If it's not serious, you can buy mineral water and drive to the repair shop. The road is closed.
