Badass is right.
Heres is a geeky explanation why:
The antifreeze/coolant is what is known as a "colligative agent", and as such, their boiling point elevation properties and freezing point depression properties are proportional (it raises the water's boiling point as much as it lowers the freezing point).
Another example of a "colligative agent" is salt. If you add salt into a pot of water that is just starting to boil (before you add pasta), you will notice that the water simmers and takes a moment to come to a boil again. That is because you just raised the boiling point of the water (only slightly though, unless you use a lot of salt).
At the other end of the spectrum, the colligative properties of salt is why it is used to de-ice the roads in colder climates. The salt mixes with the snow and slush, and lowers the freezing point of the water molecules, thereby preventing (or just postponing, depending on the temperature) ice from forming on the roads.
Anyway, thats why if you are using a 50/50 mix in your cooling system, the boiling point is well above 212 deg. leep:leep:leep: (did I put everybody to sleep with this)?
