What Is Antifreeze?

A question our service team near West Fargo is often asked is, “is antifreeze coolant?” In a sense, yes it is! While the name may imply that it keeps your car warm, antifreeze regulates your engine’s temperature while you drive Breckenridge roads.  Antifreeze is typically made from ethylene glycol or propylene glycol. Antifreeze is typically green, pink, or orange depending on its specific properties. While most vehicles take green antifreeze, be sure to purchase the proper color antifreeze for you vehicle type by checking the recommendation in your owner’s manual.

How Does Antifreeze Work?


Antifreeze is stored in your car’s radiator and is connected by a reservoir in your engine bay. Antifreeze is then circulated throughout your engine by your water pump, allowing it to carry combustion-generated heat away from your engine. The now-hot coolant is circulated back to your radiator, where it is air-cooled to remove excess leftover heat is removed. That cycle is then repeated to keep your engine running at the proper temperature.

Why is Antifreeze Important?

Antifreeze is formulated to act against overheating and to prevent your coolant from freezing in below-zero temperatures. If your engine runs without any coolant, you risk serious damage to these critical parts:

  • Head Gasket
  • Engine Cylinders
  • Water Pump
  • Connector Rods

If you notice your hood is too hot to touch, or there’s steam coming out from under your hood, you should schedule a service at our service center near West Fargo.
