Coolant container will say if it is pre-mixed or full strength. If full strenght, mix it 50/50 with water.
Pre-mixed coolant can be added "as-is"
Antifreeze keeps water from freezing when it is cold out. The antifreeze liquid lowers the freezing point of the water. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator. The antifreeze combines the water to form a liquid with a lower freezing point than water alone.
The ratio does not change from car to car, it is always 50/50 water and anti freeze. The above answer is exactly correct, except be sure and use Distilled Water and not tap water. Do not change this mix beyond 55% Antifreeze & 45% Water. Doing so will actually raise the freezing point and lower the boiling point. Beyond this point the more antifreeze you add the less protection you have.
It lowers the freezing point.
None. The freezing point of pure water is already lower than that.
It changes the freezing and boiling point.
50% water and 50% antifreeze year round.
Most antifreeze has a chemical that freezes at a very lower temp than plain water.
A sentence for the word antifreeze may be, " What is the best antifreeze to use in drinking water?" Antifreeze is a liquid which is used to lower the freezing point.
will change the boiling and freezing point of the water
It drops to about 12 degrees Fahrenheit.
Antifreeze is a substance such as glycol which is used to lower the freezing point of water, and is used as an additive in the radiators of motorcars.
Nothing, you have a solution of antifreeze. However if you then cool the solution the freezing point will be lower than that of pure water.
