Best Antifreeze and Coolants – Here are the Top 12 Offers

Best Antifreeze and Coolant

Antifreeze and coolants were originally two different liquids used in automobile cooling systems, but these days, they've become the same liquid.

Antifreeze prevents your car's cooling liquid or coolant from freezing in the winter or other low-temperature conditions. A coolant, however, prevents the water in the cooling system from boiling at standard temperatures.

As you can imagine, most car engines will overheat and eventually break down without antifreeze/coolant in the system. The variety of offers in the market, however, make this selection process a little difficult for first-time buyers.

This best antifreeze and coolants review aims to simplify that buying process for you by providing you with a list of the top offers in the market and a buying guide to make this selection process easier.

How to Buy the Best Antifreeze & Coolants

How to Buy the Best Antifreeze & Coolants

Antifreeze and coolants come in a wide variety, so you need to have some basic understanding if you want to choose the right product for your vehicle.

Following is a listing of the important aspects of antifreeze/coolants that you need to consider and keep in mind when making your choice.

#1. Types of Antifreeze and Coolants

Antifreeze coolants have evolved over the years, with better technologies invested in creating more effective and durable formulas.

There are three major types of antifreeze and coolants based on the technology that they got manufactured with. These three types are as follows:

Inorganic Acid Technology (IAT). This type of antifreeze/coolant is the bright green antifreeze that most people know. It is, however, an older formula and has since been replaced by better formulas that get used in newer cars.

You won't find IAT coolants in most vehicles made since the turn of the century because it has silicates and phosphates, which make it bad for the environment. It also includes the toxic ethylene glycol and should get changed every 30,000 miles or 2 years.

Organic Acid Technology (OAT). With organic acid technology coolants, you get a more environmentally friendly formula that isn't much of an issue if it happens to leak into the environment because it includes neither phosphates nor silicates.

It includes ethylene glycol, however, and the recommendation if to flush once in five years or after about 150,000 miles. This makes it a better antifreeze that finds use in many new vehicles. It also comes in different colors.

Hybrid Organic Acid Technology (HOAT). This one is also available in different colors and has silicates for corrosion inhibition. It's however, developed to specifically protect aluminum engine blocks.

Most of its other features are the same, such as containing ethylene glycol and needing a flush every 150,000 miles or five years. It also contains other additives for more features.

#2. Fuel Types

Coolants were originally developed differently for gasoline and diesel engines, each needing different additives to make it perfect for that type of engine that it's made for.

Most antifreeze and coolant offers that you'll get in the market today, are, however, compatible with both gasoline and diesel engines. But, always check to make sure.

#3. Formula

It's additionally important that you understand that different antifreeze formulas are ideal for different types of cars, so it's better to stick to what you've used, rather than switching to something new.

You should also avoid mixing different coolants together, especially those with different colors. Most formulas need you to use them as they are, while others need you to mix them with water. It's important that you follow these instructions.

If you ever find your car low on coolant and you have no option to buy the right type of coolant for it, keep in mind that it's okay to top off your radiator with water and slowly drive to the next gas station.

#4. Operating Temperature

You'll find that most antifreeze and coolants will offer to keep your engine working perfectly between low temperatures of -26 degrees F and highs of 250 F.

This is an ideal temperature range, but it's left for you to make sure that any product that you are about to buy offers this range or any other range that better fits your needs.

#5. Extra Points

Asides from the major factors above, there are other less important features that you may need to keep an eye on when choosing a particular product for your car.

Some formulas include extra leak-repair additives or environmentally friendly anti-corrosion additives. Also, make sure that it comes with a service life that's long enough for your car and its condition.

Another important point is having a bittering agent. Since many pets and children get attracted to the bright colors and sweet taste of antifreeze, it's important to deter them from drinking it and a bittering agent is one such good deterrent.

Conclusion

Coming to the end of this antifreeze and coolants review, you must have seen just how varied the different formulas are and how important it is to choose correctly.

From the universal solutions to the more environmentally friendly propylene glycol formulas and those designed for high-performance engines, you can see that there's an offer for every budget and engine type.

In the end, it's left for you to choose the right antifreeze coolant for your vehicle because you're the only one that knows exactly what your car needs and what you can afford.
