Antifreeze/ Coolant Buying Guide


We often forget that coolants exist and serve an important purpose in our vehicles, and that really should change. After all, without these antifreeze solutions, there’s a high chance your car won’t be running really soon.

But, when it comes to choosing the best antifreeze/ coolant for your engine, just how do you make that decision? How do you choose which one is right for you? After all, not all coolants are made the same and will give you the same performance.

In order to help you make the right choice, here are the most important things that you need to take into account when buying an antifreeze/ coolant:

What is an antifreeze or a coolant?

What is antifreeze or a coolant?First of all, let’s define what antifreeze is, and whether it’s the same as a coolant.

Technically, these two things used to be different, but with technological advancements, nowadays, coolant and antifreeze have become interchangeable terms, since both of these have the capacity to cool down a car engine and prevent it from overheating, as well as help it continue to run when temperatures are below zero.

More than the technical definition, the more important thing you need to understand is that antifreeze is an important car fluid that works in ensuring that your vehicle keeps running no matter what the weather and temperature condition.

How does antifreeze work?

But, how exactly does an antifreeze liquid do these things?

Well, the liquid is poured into the car’s cooling system and is circulated throughout the car’s engine and other surrounding car components in order to regulate temperature levels. This constant circulation is what ensures that heat from the engine is dissipated.

It works with the use of a water pump that helps it reach the heater core as well so that the interior of the car keeps a regulated temperature. Finally, the coolant returns to the radiator to cool it down, before going back again to the engine.

In many cases, plain water is used as a car engine coolant, but it doesn’t have the same temperature regulating capabilities that antifreeze has, so it doesn’t hold well in extremely hot and cold climates where high combustion temperatures and extreme outdoor temperatures are a constant issue.

How often should you change your car’s antifreeze?

Now that you have a clearer understanding of what antifreeze is and how it works, you should also understand how often you should change the antifreeze/ coolant in your cooling system so as to make sure that your engine stays running smoothly and without an issue.

Every 60,000 miles is a safe range, although it ultimately depends on how you drive your car, what condition the engine is in, and the manufacturer’s specification.

Of course, you could always just do an engine inspection, such as by looking for signs of corrosion, rust, and wearing, by testing for acidity with test strips, or by measuring the protective capabilities of the existing antifreeze with the use of a hydrometer.

It all depends on your car

To expound further on what I’ve said earlier, different car makes and models have different recommendations on what type of coolant to use and how long before this coolant must be changed.

You can get a range of as low as 30,000 miles for old Hyundai cars and as high as 150,000 miles for top of the line Chevrolet and Mercedes Benz vehicles.

Generally, the newer model your vehicle is, the longer it takes before you need to replace any sort of engine fluid, since these vehicles have been made more efficient and with less environmental footprint.

Tip: Replace before you have to

A good practice is to replace your engine coolant or antifreeze if you’ve already put in significant miles, even when tests show that the fluid still works in cooling down your engine. That’s because at some point, it loses its rust and corrosion resistance properties.

So, essentially, you just have glorified water as your coolant that does nothing in protecting the engine from deterioration and damage, and with no antifreeze properties to help regulate the engine under extreme weather conditions.

Things to Consider Before Buying an Antifreeze or Coolant

Things to Consider Before Buying an Antifreeze or CoolantThe best thing you can do to ensure that you find the right type of antifreeze/ coolant for your car is to consult with your car manual, but as an added information to let you know what’s what, here are the most important factors that need to be taken into account when buying the best antifreeze/ coolant:

Type of fuel

The most important factor perhaps when it comes to engine coolants is the type of fuel that the engine itself runs on, since the coolant is formulated to work on specific types of fuel. This is because diesel and gasoline engines have different requirements on what types of properties the coolant should have.

For example, diesel engines are more susceptible to corrosion and thus require superior corrosion resistance from the coolant, which is achieved by mixing supplemental coolant additives.

Type of coolant

There are also different types of antifreeze based on the type and age of the vehicle and engine. These coolants are made with different formulations and ingredients depending on the existing technology of automotives at the time.

For example, old car models made in the early 1900s up to the late 1990s make use of inorganic acids, and therefore contain silicate and phosphate, whereas newer vehicle models make use of organic acids that work better for aluminum car parts and components. These coolants also last longer than inorganic ones.

And then there are hybrid organic acid coolants, which contain silicate and nitrates that are more suitable for Asian and European automotives.

Ethylene glycol vs propylene glycol

There are also coolants made with ethylene glycol and propylene glycol, and each one has its own benefits and downsides. For example, ethylene glycol is more efficient and works better under lower temperatures.

On the other hand, propylene glycol is more suitable for tropical locations, and is not as toxic and harmful to the skin in case of accidental contact.

Ease of use

One thing you might want to consider that is largely up to your personal preference is how easy to antifreeze/ coolant is to use, meaning, whether it requires any prior preparation, or if you can just pour it into the cooling system directly from the bottle.

To give you an idea, there are antifreeze solutions sold as pre-diluted formulations that already contain a 1:1 ratio of water and coolant, while others are concentrated and require diluting at a specific ratio to work best for your car given specific conditions.

Temperature range

Another highly important consideration when it comes to antifreeze/ coolant is the temperature range that the engine will mostly be operating under, which largely depends on the climate and weather conditions of where you live.

For example, colder weathers require a higher concentration of coolant versus water, so that you get more antifreeze and protect the engine better from failing to start due to cold weather. A good ratio here would be 60:40, or even 70:30 if the climate is really cold.

On the other hand, warm and tropical locations would do just fine with a standard 50:50 mixture of coolant and water.

Overview


Antifreeze/ coolants play an important function in ensuring that your car engine runs smoothly and doesn’t encounter any problems due to extreme internal and external temperatures. These fluids also keep your engine safe from damage due to rust and corrosion.

As such, it’s only natural to want to purchase the best antifreeze/ coolant for your vehicle so that you can get the best possible engine performance for the longest time possible. As long as you know the things to look out for, you’re sure to find a coolant that works for you and your car.

My best recommendation for you is the Evans EC53001 High Performance Waterless Coolant, a highly rated and high performing antifreeze/ coolant that works for all types of vehicles and engines, and offers superior protective properties to keep your engine in peak condition for longer.
