  • What is antifreeze?

What Is Antifreeze?

Our service department often sees Fort Wainwright drivers who want to know, “is antifreeze coolant?” If you were to compare coolant vs. antifreeze, you would find that, yes, in a sense, they are the same thing! The name may imply that antifreeze keeps your car warm, but what it actually does is regulate your engine’s temperature while you drive.

Typically, antifreeze is comprised of ethylene glycol or propylene glycol. It is either green, pink, or orange in color, depending on its properties. Most vehicles take green antifreeze, but you should check your owner’s manual first to ensure you purchase the proper color for your make and model.

What Is Antifreeze Used for?

Antifreeze is stored in your vehicle’s radiator and is connected by a reservoir in the engine bay. It gets circulated throughout your engine by the water pump, which allows it to bring combustion-generated heat away from your engine. The now-hot coolant is then circulated back to the radiator, where it is cooled by air to remove excess heat. This cycle is constantly repeating while you drive, working to keep your engine running at a safe temperature.

Why Is Antifreeze Important?

Antifreeze is vital to keep your vehicle running safely in Eielson Airforce Base. It is specially formulated to prevent overheating and keep your coolant from freezing in below-zero temperatures. If you were to run your engine without any coolant in it, you’d risk major damage to these critical components:

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

If your hood is ever too hot to touch or there is steam coming out from under it, you’ll want to schedule an appointment at a local service center immediately.
