Coolant, also known as antifreeze, serves two purposes in a cars engine.
(1) Coolant keeps the engine cool.
During the summer especially, your engine can get very hot. We all know that when water gets hot enough, it boils. Have you ever seen a car on the side of the road, with a bunch of steam blowing out of the hood? That is a car with an over heated engine. Coolant can still boil like water, however coolant has a higher boiling point than water.
(2) Coolant also keeps the engine from freezing.
This is very important. If your cars engine has water in it, instead of coolant, and the outside temperature drops below freezing, your engine may become susceptible to becoming frozen. If your engine freezes from sitting in the cold without coolant, the water inside of the engine will expand. When ice expands it has to go somewhere. You engine will crack and will not be repairable. Coolant can still freeze, but unless your using the lowest grade coolant, and your driving through Alaska, your coolant probably won't freeze. How does coolant both keep the engine cool when running, but keep it from freezing too? Its simple; Coolant has a higher boiling point than water (99.7'), and it has a lower boiling point than water (32'). The temperature highs and lows vary with the type of coolant you use.
!CAUTION! When your coolant level goes down, due to evaporation or leaks, you may out water in your radiator for a temporary fix. HOWEVER this alters the highest and lowest points of your coolants temperature peak. MORE WATER = WATERY COOLANT
What else can I help you with?
Does putting water on coolant tank bad?
It can be. If you live in a cold area it could freeze. If you live in a hot area, it could boil. On collant bottles, it will tell you not to use collant or water alone. It will tell you the proper mixtures to use.
What would happen if cars would use water instead of gas?
we would run out of water quicker
Why do people in Italy use gondolas instead of cars?

well, if you use water instead of milk, it will no longer be milk. it will be colour changing water.
Can you use water to replace oil used for cars?
no
What are other efforts to help prevent global warming?
You can use electric and solar powered cars instead of gasoline cars;but if you do use a gasoline car, carpool often to use less gas.
Why do cars use alternators instead of generators?
Cars don't use generators because the batery is already generating energy. They use alternators in order to convert the energy generated into a usable form.
Do cars run with water?
No, cars use internal combustion engines which require a flammable fuel. There is a 50/50 mixture of water and antifreeze use as a coolant in the engine.
Can you use mineral water instead of boiled water?
Depends on what do you use it for. Generally, yes, you can.
What should you use instead of bottled water?
