When ice freezes, it expands with heat and contracts with cold. As soon as it expands, it loosens those sealed places. It melted as soon as it was loose, and then the place leaked. This is not cost-effective. I suggest you replace it in advance. But what if you are really frozen?
First, if you don't use glass water in a hurry, the ice can be ignored. With the heat of the engine, it will melt in a day or two as the temperature rises slowly. Maybe a little further north in the northern region, the temperature will continue to be low and will not melt.
The second most direct way is to drive the car to the basement. Many places in our country have such underground parking lots. Under normal circumstances, the temperature in the basement will be above zero. Just stop for one night, take the car out the next day, and it basically melts.
The third stupidest way is to find the lid of the glass water and open it. If there is any surplus, you can add antifreeze glass water or water with a little temperature, but you can't heat the water. If you heat the water, it may be useless below. Moreover, after adding antifreeze glass water, it can prevent from freezing again. Finally, after your glass water tank is thawed, pay attention to see if there are any signs of dripping or leaking at the bottom when parking. Because after many cars freeze and melt, those sealed gaps may loosen or crack. There will be signs of water leakage at this time. If there is water leakage, repair it in time.
