Antifreeze vs. Coolant

What's the difference between coolant and antifreeze? What is coolant? When do I use either? These are common questions for car owners.

The short answer is that coolant is made from antifreeze and water. Coolant is 50% water and 50% antifreeze. The addition of water distinguishes antifreeze from engine or radiator coolant. You can buy 100% antifreeze and mix it yourself with 50% water to become coolant, or you can buy it premixed.

Coolant protects the engine and metal parts that it touches from corrosion. Antifreeze regulates temperature.

Antifreeze, usually lime green, is made from ethylene glycol and used to keep your engine parts from freezing in winter. It does this by lowering the freezing point of the liquid from 32 degrees Fahrenheit to about -35 degrees.

This same product also keeps your engine from overheating in the hotter months, raising the boiling temperature up to 275 degrees F.

Whatever you prefer to call it, coolant will need to be completely flushed and replaced occasionally to remove buildup and prevent unnecessary repairs to your engine and connecting parts.
