Ever since 1926 when ethylene glycol was first used as an automotive antifreeze, our vehicles have used some form of antifreeze consistently.

Primarily, antifreeze is a fluid mixture that’s used to transfer heat out of an internal-combustion engine.

Additionally, it’s used to protect engines from freezing in colder-weather climates. Along with these important functions, it also is a corrosion inhibitor; it lubricates the water pump; and it reduces foaming.
