Antifreeze Fundamentals

Antifreeze Fundamentals

Antifreeze/coolant does more than you might think.

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.
