What is Antifreeze?

Man Filling Antifreeze Fluid in His Car


Most Wilsonville drivers know that antifreeze is that fluid that goes into your car’s radiator. But what is antifreeze, exactly? Is antifreeze coolant? What is antifreeze used for? These are important questions that you should know the answer to. Our service department wants to help keep your car running safely and in top shape, so we’ve put together the guide below.



What is Antifreeze, Exactly?

Antifreeze is the fluid that runs through your coolant system, which includes the radiator, water pump, and various connecting hoses, among other components. What is antifreeze made from? This fluid is composed of ethylene glycol or propylene glycol. It comes in one of three colors: orange, pink, or green. It’s very important that you fill your car’s coolant system with the right color, so check your owner’s manual before putting any antifreeze in your car.

Is Antifreeze Coolant?

You’ve likely heard that fluid that is used to fill your car’s radiator referred to as “coolant”. Is antifreeze coolant? Not by itself. Coolant is actually antifreeze mixed with water. That’s why this fluid often comes premixed with an exact percentage of both antifreeze and water. Never pour unmixed antifreeze into your car’s coolant system. Check your owner’s manual for the mix that is right for your car.

What is Antifreeze Used For?

So, what is antifreeze used for? It actually serves two purposes. One, it keeps the coolant in your car from freezing during our cold Portland area winters. And, two, it keeps your car from overheating. Either freezing or overheating could seriously damage your car’s engine, maybe beyond repair. So, it plays a vital role in maintaining the health of your car.
