Boiling Point Elevation
The boiling point of a solution is higher than that of the pure
solvent. Accordingly, the use of a solution, rather than a pure
liquid, in antifreeze serves to keep the mixture from boiling in a hot
automobile engine.....

Actually, no. Ethylene glycol in its pure liquid state boils near
200 degC

It is usually cut to 50% dilution for use as an antifreeze.
