If you mean the water in your radiator, don't drive your vehicle until it thaws or your engine will overheat because no coolant will be flowing through it. You should keep 50% antifreeze and 50% distilled water in your car radiator at all times. (maybe slightly more antifreeze in cold winter weather) Water in the radiator won't freeze with antifreeze mixed with it.
Because the engine is still running while in neutral. Your problem is probably your radiator or lack of antifreeze. Antifreeze serves as what it's name implies and as as a coolant. Additionally since the automobile is not moving forward the radiator is not receiving ventilation provided by the incoming air.
That's what it's meant for. But then again it depends on what type of radiator you are talking about. It's meant for automobile radiators. Just make sure you don't spill it or allow anyone/anything to drink it. It can kill you.
None. The freezing point of pure water is already lower than that.

We always renew the antifreeze in our car before winter.
