increases, and lowers
It changes the freezing and boiling point.
The antifreeze in the radiator stops it seizing
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.
Most antifreeze has a chemical that freezes at a very lower temp than plain water.
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.
I believe a 50 / 50 mixture of antifreeze and water freezes at - 34 degrees Fahrenheit
Doubtful !... The antifreeze is added to the radiator - to keep the water above freezing point. There is no way of the engine knowing how much antifreeze is circulating.
During Winter or whenever it is cold to lower the freezing point of the water in your car radiator. :] F
they do this to lower the freezing temp of the water so then it wouldd have to drop below 0 degrees.
antifreeze does two things. It keeps the water in the radiator from freezing in the winter, and helps prevent if from boiling over and evaporating in the summer. You can run your vehicle with water alone in moderate temperatures and it will do the job. But, if you mean by "running out of antifreeze" you mean there is no liquid in the radiator, then yes, your vehicle can overheat and ruin the engine.

A 50/50 mixture of water and coolant/antifreeze is highly recommended to avoid freezing and/or rusting within the radiator.
