What’s the difference between antifreeze versus coolant?
In some ways the discussion about Antifreeze versus Coolant is just semantics since both liquids prevent freezing and protect against cooling system corrosion. Ten years ago the terms were interchangeable, but not anymore. Here’s what’s changed
Antifreeze is concentrated and must be diluted with distilled or de-ionized water. The most popular dilution rate is 50:50
Coolant is pre-diluted by the manufacturer. In other words, you can pour it right into your engine.
