What Is Antifreeze?

Our service department often assists Apple Valley drivers who wonder what antifreeze coolant is. While some use the terms interchangeably, coolant is a mixture of antifreeze and water. Coolant commonly consists of 50% antifreeze and 50% water, but more potent (and more expensive) options can be 70% antifreeze and 30% water.

Typically, antifreeze is composed of ethylene glycol or propylene glycol and can be green, pink, or orange depending on its specific properties. Most vehicles use green antifreeze, but check your owner’s manual first to ensure you purchase the proper color for your make and model.

So, is antifreeze coolant? Initially, it might sound like antifreeze and coolant achieve opposite results, but this isn’t necessarily true, as you’ll see below. As it turns out, the properties of antifreeze (and therefore, coolant) enable it to keep your engine cool when hot and prevent freezing when cold. Read on to learn more!

What Is Antifreeze Used for?

Antifreeze is stored in your vehicle’s radiator and is connected to a reservoir in the engine bay. It is circulated throughout your engine by the water pump, which moves combustion-generated heat away from your engine. The now-hot coolant is then circulated back to the radiator, where it is cooled by the air that flows in from the grille. This cycle repeats continuously while you drive and helps keep your engine at a safe temperature.

Why Is Antifreeze Important?

Antifreeze is vital to keep your vehicle running safely in Barstow. It has a higher boiling temperature and a lower freezing temperature than water. These properties help prevent your engine from overheating when hot and from freezing when cold. If you were to run your engine without any coolant in it, you’d risk significant damage to these critical components:

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

What kind of damage might your car sustain if you run it without antifreeze? Excessive heat, for example, can warp engine components and increase wear and tear. Plus, evaporating water can accumulate, leading to rust. If your hood ever gets too hot to touch or there’s steam coming out from under it, you’ll want to schedule an appointment at a local service center immediately! On the other hand, liquid expands in the cold, which can crack the engine block. Both issues will necessitate expensive repairs, and a cracked engine block can even result in a total write-off.
