What Is Antifreeze?

First things first, Antifreeze is a liquid that usually comes in a variety of different bright colors, such as green, orange, blue and pink.

This substance runs through the your car’s radiator, which is the cooling system for your vehicle.

It has a few specific and important jobs to do, and we’ll cover those in more detail below. At the most basic level, though, it’s a liquid that is mixed with water in order to cool your engine.

Water on its own can’t stop your engine from overheating, because water freezes at low temperatures and boils at high temperatures. It reacts to the temperatures, instead of helping regulate them. So can you use water as a coolant? Only in an emergency, but it’s not recommended.

And this where antifreeze can help. The best engine antifreeze coolant products out there are able to decrease water’s freezing point and increase its boiling point effectively. This means that the water won’t turn to ice or to steam vapor as quickly as it does without antifreeze.

In other words, antifreeze ensures that water stays in liquid form, cooling down the engine and lubricating all the components.

All of this is achieved through various chemicals, with the most common one being ethylene glycol.

What Are the Benefits of Using Antifreeze?

First of all, your vehicle needs help to regulate its temperature, since it can’t do this on its own. Car engines have to remain at a safe operating temperature to work properly.

With the help of antifreeze, all of the engine components can be lubricated, which prevents friction between the parts that produce heat.

If the product helps lubricate your car’s engine, as well as control high temperatures, you may be asking yourself “why in the world is this thing called antifreeze?!”. That’s because one of its main functions is to stop your vehicle’s engine from freezing in severely cold climates.

While it’s running, your engine stays warm, but it will start to cool down once it’s turned off. If there is no antifreeze, you could develop ice in your engine when the temperature outside is too cold.

As you probably already know, when water turns to ice, it expands. This can happen inside your engine if your vehicle is sitting outside in freezing temperatures, and could very well cause expensive damage that would be extremely costly to repair.

Antifreeze enables your engine to start and run smoothly and efficiently, no matter what the weather’s like at the time. It helps your car withstand extreme temperatures, and it’ll ensure that the metals of your radiator don’t corrode with water exposure.

Plus, some of these products have additives in them that can help keep your engine clean, too. These may help stop the buildup of deposits that could damage your vehicle over time.

What Different Types of Antifreeze Are There?

There are many different brands of antifreeze on the market for you to choose from, but that’s not all there is to it. B

Before you try to go through all these brands and their different products, you have to know which type you need first. This can get a little complicated, so let’s break it down so that it’s easier to understand.

Let’s look at the two broadest categories first: Concentrated antifreeze and diluted antifreeze.


As the name suggests, this is a product with concentrated oils and chemicals.

There isn’t any water mixed in already–it isn’t premixed–you’ll need to dilute the antifreeze by yourself before you put any of it in your car.

This is normally done at a ratio of 50 percent water and 50 percent antifreeze, but this isn’t always the case, so it’s vital to read the instructions carefully at first to understand how to mix the liquids correctly.

Important: Tap water shouldn’t be used to dilute the mixture, except in an emergency and if you absolutely have no other choice. Mix with distilled water instead or, better yet, deionized water.


The second category is ready-mixed, or diluted antifreeze. This is a product that’s ready to go directly into the coolant system of your vehicle as it is.

A lot of drivers choose this option because it’s great for topping up the fluids in a simple and quick manner.

In addition to these the two categories (concentrated and diluted), there are three main types you can choose from as well. These vary according to their composition and the engines they are appropriate for.

Inorganic Acid Technology (IAT)

Antifreeze that uses inorganic acid technology (IAT) is typically suitable for older vehicles.

(Video) TOP 5 Best Antifreeze Coolant [ 2023 Buyer's Guide ]

It usually contains ethylene glycol, as well as silicates, phosphates and borates. These are all ingredients that work to keep copper and brass radiators in working order.

Vehicles that use IAT antifreeze only require it to be changed every 30,000 miles or 2 years.

With all that being said, chances are that unless you’ve got an older car, you won’t use IAT antifreeze. This is mainly because unlike the other types, it doesn’t have corrosion inhibitors for modern engines.

Organic Acid Technology (OAT)

Often referred to as extended life antifreeze (or long life antifreeze), these products use organic acid technology (OAT).

This is mostly used in vehicles manufactured from around 1996 onwards, which aren’t compatible with IAT. OAT antifreeze is going to be an option for cars with aluminum or cast-iron radiators.

OAT antifreeze contains corrosion inhibitor properties which protect the engine from wear and tear, and doesn’t contain silicates or phosphates that can be damaging.

In general, this type should be changed approximately every 5 years or 100,000 miles.

It should be noted that OAT shouldn’t be used in older engines if they contain brass or copper.

Hybrid Organic Acid Technology (HOAT)

The third type is called hybrid organic acid technology (HOAT), and is usually found in antifreeze that’s suitable for most modern cars and for aluminum radiators.

It’s usually a mix of silicates and OAT corrosion inhibitors and often used in European vehicles, but the Japanese tend to use phosphates instead of silicates.

HOAT antifreeze is extremely long lasting and can be changed after about 10 years or 180,000 miles.

What Type of Antifreeze Do I Need for My Car?

Most of us won’t know what type we need off the top of our heads.

To find out what’s the best antifreeze for your vehicle, you should check the owner’s manual for your car. This is going to detail the exact product that works best in your car’s radiator and do a good job at protecting your engine.

But, what exactly do you do if you don’t have your owner’s manual? Well, that’s not really a problem in this day and age.

If you’re still in doubt as to what the best type for your vehicle is, you can ask around at the car dealership. Professionals there should be able to point you in the right direction, and tell you what you’re best off going with.

If you don’t want to do that, then that’s fine as well – you can also try to look up your vehicle’s specs online and find out for yourself.

What If I Use the Wrong Type of Antifreeze?

Let’s say you’ve accidentally used the wrong type for your vehicle – what should you do now? It may not be the biggest problem in the world, but it’s best to err on the side of caution.

The best thing you can do if this happens is flush the coolant system in your car as soon as possible. This may help you avoid possible engine failure later on.

When you top up or refill with the wrong antifreeze, this could create a damaging mixture. The result could be that liquids stop flowing, causing the engine to overheat.

This might not only put your car out of commission and cause great inconvenience—it could also mean costly repairs you’ll have to pay for down the line.

So, if you’ve accidentally used the wrong product, flush it out immediately. For those of you who need guidance on how to do so, this video walks you through the necessary steps.

What Different Colors Are There for Antifreeze?

Many years ago, a lot of manufacturers would use different colors to identify different types of antifreeze.

For example, IAT antifreeze would be green, while OAT was typically orange, red or purple, and HOAT would also be orange or yellow.

Nowadays, you can’t reliably use the color of antifreeze to identify its type, as things have changed since then. These days, manufacturers can use whatever color they want for their product regardless of its type.

So, be sure that you always read the information on the bottle before you purchase any, just to make sure you’re getting the right type for your vehicle. This will guarantee that you don’t waste your money on the wrong product.

The Differences Between Antifreeze and Coolant

One of the most common questions we come across is whether antifreeze and coolant are the same thing. We understand where this confusion comes from, since the terms are often used interchangeably, but it should be noted that these two are not the same.

Antifreeze is a combination of chemicals that work to cool your engine when mixed with water. Once it’s diluted, antifreeze becomes a coolant.

Concentrated antifreeze, on the other hand, needs to be added to water before it becomes a car coolant. Only then will it work to lower the temperature of your engine. On its own, concentrated antifreeze will not act as a coolant.

When you hear someone refer to engine coolants, they are referring to antifreeze that is either pre-diluted or has been manually added to water.

What Is Antifreeze Made Of?

Usually, antifreeze is made of a base product with some additives in there as well.

Let’s take a closer look at the common ingredients you’ll find in these products on the market today.


Methanol is a colorless liquid that is found in a range of car products. This includes antifreeze, de-icers and windshield washer fluid.

It’s able to effectively lower the freezing point of water, but it’s important to remember that it’s toxic.

Ethylene Glycol

Ethylene glycol is a popular substance found in antifreeze. As a matter of fact, this is the one you’ll hear about most.

(Video) Top 5 Best Coolant Additives in 2023 [Reviews & Buying Guide]

One of its main benefits is that it’s not going to damage the metal in the radiator of your car. However, like methanol, ethylene glycol is also highly toxic to humans and animals.

Propylene Glycol

If you’re looking for a non-toxic option, choose one that contains propylene glycol. This is commonly used in non-toxic formulas instead of ethylene glycol.

Propylene glycol is also great for heat transfer and will help to protect your engine from corrosion.

What Should I look for in Antifreeze Products?

With so many products out there on the market to choose from, it cal be difficult to know where to start.

So, to simplify the process for you, there are a few features you should be looking for when you’re trying to choose the best coolants possible.

The following is a list of the key elements you should consider:

Protection From Low and High Temperatures

You want to make sure that you choose something that does a good job at preventing your engine from both freezing and overheating. After all, this is what this liquid is supposed to do!

So, be sure to choose a product that regulates the engine temperature no matter what season it is.

To be sure about this, look out for an antifreeze that lists the lowest and highest temperatures that it will be effective under. This way, you can choose one that suits your local weather conditions.

Corrosion Inhibitors

You ideally want corrosion inhibitors included in the formulation you’re buying.

This is going to protect your engine from wear and tear, boost the performance of your vehicle, prevent leaks, and clean the metal components.

Choosing one that contains corrosion inhibitors is going to pay off in the long run; it could prolong the life of your engine!

A Long Shelf Life

While you should definitely do your best to stock up on the best antifreeze coolants you manage to get a hold of, this isn’t a product that’s going to last forever.

It does have a shelf life, and that’s why it’s best to look for one that’s going to last you a long while.

For example, some of these products will last for three years, while there are others that will last up to 10 years. Check out the product information to make sure of this before you make a purchase.

Can Different Types of Engine Antifreeze be Mixed Together?

It’s not recommended to mix together different types of antifreeze. With all of the different chemicals they contain, mixing them could cause a bad reaction, which might ultimately seriously damage your engine rather than help prolong its life.

In particular, you shouldn’t combine IAT and OAT types of antifreeze. This is because these formulas are normally used in antifreeze products for different types of radiators.

As we’ve explained earlier, IAT is suitable for brass radiators, while OAT is used for aluminum. You risk damaging your engine if you mix them together, or use one while your car needs the other.

With that being said, this isn’t always the case, as some products are specifically made to be compatible with other formulas. These ones can usually be used safely as a top-up.

Always be sure to read the bottle or instructions properly before you do this, however, to avoid unnecessary damage and repairs.

If you do mix two different types together by accident, it’s best to drain your coolant system immediately, as mentioned above.
