At atmospheric pressure (that is, with the radiator cap loose or off, and the vehicle at sea level) coolant (50% water and 50% ethylene glycol) boils at 227 degrees F. At 15 psi pressure (the typical pressure at which a radiator cap will vent steam and therefore the typical maximum pressure within a closed cooling system) the same 50/50 mixture will boil at 265 degrees F. (Obviously, with the radiator cap tight it won't matter whether the vehicle is at sea level or not.)
Different mixtures of water and ethylene glycol have different boiling points, of course, and different freezing points, too.

When ethylene glycol is added to water the melting point of water is?
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
What happens to water when antifreeze is added to it?
The boiling point increases and the freezing point decreases.
Is there any difference between boiling point of water and blood?
Yes, for many reasons, just a few of which are: water is a compound and blood is a mixture the water component of blood also has compounds dissolved in it (water-based solutions have higher boiling points than water itself...this is why the water/antifreeze solution in your car doesn't boil at 100° C).
What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
What is the melting and boiling point of milk?
The melting and boiling point of milk are very similar to the melting and boiling point of water.
Does antifreeze boil at a lower temperatures than pure water?
The mixture of the two liquids (water and antifreeze ethylene glycol))has a higher boiling point and lower freezing point than water alone.
What is the boiling point of a antifreeze--water mixture?
50/50 mix with 15 P.S.I. rad cap ( 265 degrees Fahrenheit / 129 degrees celsius )
How does an antifreeze prevent freezing in cold months and overheating and boiling?
It lowers the freezing point and raises the boiling point of water.
What are physical changes of antifreeze when dissolved in water?
will change the boiling and freezing point of the water
Why does antifreeze boil faster than water?
It does NOT boil faster than water. It has higher boiling point AND lower freezing point. - Antifreeze boils at about 197 c.
How can you separate a mixture of alchohol and water?
Distillation! Water and alcohol have different boiling points; one is lower than the other. Heat the mixture up until it one of the two boils away. In the case of alcohol and water, alcohol has the lower boiling point. Heat the mixture to just above the boiling point of alcohol but below the boiling point of water and voila!- you've separated the mixture.
Why cars use of antifreeze in summer?
Antifreeze also raises the boiling point, has lubricants for the water pump, and has corrosion inhibitors in it.
How does antifreeze keep the water in your radiator from freezing and overheating?
It changes the freezing and boiling point.
Does adding antifreeze to a car radiator increase the boiling point of the water in the radiator?
Yes
How antifreeze affects the freezing point of water?
It lowers the temperature where the mixture will freeze
State two quantitative physical proparties that change when antifreeze is dissolved in water?
It chances the boiling point of the water, and it changes the freezing point of the water
Is antifreeze added to car radiators to lower the freezing point of water?
Yes. The antifreeze/coolant also raises the boiling point and has lubricant and anti corrosive properties.
