So that the fluids don't freeze. When a liquid freezes it expands this can burst pipes and tubes, the frozen liquid also blocks the circulation of that liquid so that it can not do the job it is supposed to do. Antifreeze contains alcohol and other substances that freezes at a much lower temperature than water.
no but if in the winter you do not put in the car the engine will freeze you can also use water during the summer No!
So that the coolant can stay in liquid form and flow through the cooling system.
Because antifreeze is also coolant. (basically a temperature regulator) keeping your fluid from freezing in the winter and from overheating in the summer. It also contains anti-corrosion additives.
