Why You Should Never Use Pure Antifreeze as Coolant in Your Cars or Trucks

Antifreeze is a chemical, primarily consisting of ethylene glycol, which, when mixed with water, serves to lower the freezing point and raise the boiling point of the mixture. Traditionally, the combination of antifreeze and water is known as “coolant,” but why should you mix Antifreeze wouldn’t it work better if you used it straight from the bottle?  I decided to find out. Why you should never use straight Antifreeze in your car or truck?

You should never use straight Antifreeze in Your Car or Truck because

  1. Antifreeze made from ethylene glycol freezes between 0 & -5 °- only when it’s mixed with H20 does its freezing point lower
  2. Antifreeze Coolant has no heat-transfer abilities unless mixed with H2O
  3. H2O must be mixed to keep additives suspended

Preparing your vehicle for the winter is also a good time to check your coolant’s antifreeze.  Coolant is the fluid in your radiator, while antifreeze is the liquid being added to the radiator to help prevent the coolant from freezing.


Why You Should Never Use Pure Antifreeze as Coolant in Your Cars or Trucks


I’m here to tell you about a ‘no-no’ that even I know to avoid. You see, pure antifreeze, or glycol as some call it shouldn’t be used at full concentration in a car’s cooling system. Yep, you heard it right, NEVER use it pure.

The mix we use in our cars as coolant is a blend of antifreeze and water. If you think you can save a buck and use pure antifreeze or straight anti-freeze, as some call it, in your cooling system, I’m here to tell you it’s a big risk and a serious car-care mistake.

See, the thing with antifreeze is that, yes, it’s great to help protect your engine from freezing up on those chilly winter mornings or nights but it also has a job to do during the hot summer months. And when I say a job, I mean, it’s like me in our school on summer break – working my tail off to make things cool. And it can’t do that work if it’s used in a concentration that’s too high.
Antifreeze carries heat away from the engine and out to the radiator where it can cool down.

But guess what? Pure antifreeze will actually carry less heat than the same amount of water. So you can see why it’s not a good idea for you to use only it. You’ll end up with an overheating car, and that, my young scholar, is a no-no.

Have you ever had that one kid in your class who always asks a million questions? C’mon, we all have them, right? Well, the question about why not use pure antifreeze is just like that. To put it simply, it’s all about the boiling point.

Water boils at 212F, whereas antifreeze boils at a higher temperature. This gives your engine an extra safety margin. But the big ‘but’ here is that too much antifreeze in the mix actually reduces it to less than the boiling point of water. So not only will your engine heat up quicker, but that heat has nowhere to go. It’s a recipe for disaster.

And let’s not forget about our old friend, oil. Oil is what keeps the moving parts of your engine slick and minimizes friction, which, in turn, reduces heat. Using pure antifreeze can cause the oil to heat up excessively, leading to engine wear and potential failure. You want to avoid your car turning into the automotive equivalent of a geyser.

So, next time your car needs a coolant top-up or change, remember- never, and I mean NEVER, use pure antifreeze in your car! Remember these facts peeps, they might just save you a bucket load of money one day. And no matter where you are on your car journey, MyWaterEarthSky’s always happy to share the knowledge, tips, and tricks to help you out!


The Role of Antifreeze and Coolant in Car Maintenance


Alright, so firstly, you need to keep up with basic car maintenance tasks, right? Like changing the oil, keeping an eye on the tire tread, and making sure the engine’s running smoothly. Now, a vital part of that engine maintenance involves; you guessed it monitoring the coolant.

But here’s where the plot thickens: while coolant is super-duper important in running the show under the hood, it isn’t exactly your conventional antifreeze. Confusing, isn’t it? But don’t you worry, it’s not as tricky as you might think.

See, a lot of folks assume that antifreeze and coolant are the same thing. Not true. While some part of coolant does comprise antifreeze (just to stop the engine from freezing up on those frigid winter mornings), you shouldn’t try swapping out the coolant in your car for pure antifreeze. Don’t even think about it! Why, you ask? Well, that’s the question, and we’re here to answer it.

Unlike antifreeze, which is pretty stagnant as its main job is to guard against freezing, the role of coolant is much more active. The coolant’s activity circulates throughout the engine and helps dissipate heat. It’s part superhero, part…er, water. This special mix keeps your engine from getting too hot or cold it’s got to be ‘just right’.

But if you replace the coolant with pure antifreeze, the problem! Pure antifreeze doesn’t have the same magic properties as the coolant mix and could actually harm your engine in the long run. So remember, although your car and all cars might seem like beasts that can gulp down any liquid you throw at ’em, be cautious about what you pour into them because it could pose serious risks.

So, to round up this engine-licious chat: you need to understand that the role of coolant in maintaining your car’s engine is critical. Don’t let your car thirst for coolant while you’re stuffing it full of pure antifreeze it just ain’t right! It’s like feeding your dog sure, he might love it, but it’s not gonna do him any good.

Now that we’ve put that question to bed, you should be feeling ready to tackle any coolant-related conundrums that come your way! So keep those engines roaring and remember the wielder of coolant wears a crown! Until next time, this is MyWaterEarth&Sky signing off and reminding you to treat your cars with care. Remember folks, home is where the car is!


Oil and Coolant Compatibility: Reviews and Recommendations


Here’s some pretty neat stuff that all you future gearheads in our lil’ automotive enthusiast community need to know about. See, when it comes to our beloved cars or big trucks, oil and coolant are the lifeblood running through their engines. Now, I may not be the largest automotive expert at MyWaterEarth&Sky but let me tell you, when it comes to looking at reviews or working on projects, I sure do get my hands dirty!

Honestly, if cars had a central hub, it’d be the engine, no doubt. But here’s a tricky question – are oil and coolant compatible? The short answer is, that they need to be for your engine to work right!* The longer answer…

First, let’s take a closer look at oil. This slippery stuff keeps your engine parts moving; around smoothly and easily, preventing friction-induced wear. Basically, oil is the protective armor of the car. However, change comes to us all, and oil is no different. So when you’re done racking up the miles, make sure you get an oil change!

Next in line to the throne, we got coolant. Now this might raise an eyebrow or two, but coolant…well, cools your engine. Without it, you’re risking your engine overheating, and trust me, that ain’t a barbecue party you want to attend. But here’s the catch – you should never use pure antifreeze as your coolant of choice!

Wait a second didn’t we just say antifreeze and coolant are the same? Yes, but…not quite! You see, in reviews, you often see coolant and antifreeze being used interchangeably, but they are really two halves of a whole. This might be a bit confusing, so let’s take a breather and slowly piece this puzzle together…

Pure antifreeze, as the name indicates, stops your engine’s water from freezing when it’s colder outside than a snowman’s nose. Sounds handy, right? But here’s the kicker – it doesn’t cool your engine as well as a mixture of water and antifreeze does. So, when some folks recklessly use pure antifreeze as coolant, they’re actually causing more harm to their car in the long run.

The right ratio of antifreeze to water usually rests at 50:50, but always check the user manual to get the specs for your specific ride. And remember, whatever you don’t let your car become a post count in the ‘engine failure’ thread of our largest automotive enthusiast community.

To answer a follow-up question I know may be on some of your minds, can coolant and oil mix? Well, that’s a big no-no in my book, guys! That just leads to all kinds of engine complications, which is a whole different ball game. But that’s a lesson for another day!

Last but not least, show your car some love. It’ll thank you with every purr of the engine and smooth mile down the road. Until our next revved-up chat, keep those engines humming and radiators cool.


What Are the Different Colors Of Antifreeze


To help you a little more take a look at the color of antifreeze is generated completely by coloring dye, not as a direct result of any chemicals mixed during the manufacturing of the product.

That said, different colors for antifreeze do exist. Specific colors are agreed upon by the auto Industry.

The ingredients are basically the same, but there are some basic variations between the products. The main antifreeze colors you’ll run across are traditionally green, extended-life yellow, and extended-life pink or orange. In more recent years, some Korean automakers have even been using blue dye antifreeze.

Use only the color that is recommended by the manufacturer of the car or truck you bought, and never mix two different colors. Even when a label says the mixture is Universal, don’t use it!

Green Colored Antifreeze 

For many decades, virtually all anti-freeze was dyed florescent green and made of ethylene glycol. This type of traditional antifreeze uses “Inorganic Acid Technology” (IAT) as a chemical basis and usually contains silicate or phosphate additives to prevent corrosion of metal cooling system components.

This type of Green Antifreeze is highly efficient and less harmful. There has been a movement in recent years to replace ethylene glycol with propylene glycol, which is less harmful if ingested. It’s also less harmful to Pets and the Environment. Green Antifreeze is fairly safe now because of those recent efforts.

Orange & Pink Antifreeze Organic Acid Technology (OAT) Type Coolants

Antifreeze that’s dyed Orange and pink features a newer class of corrosion-preventing inhibitors since 1996 that was developed, known as organic acids. They do not contain the silicates or phosphates found in abundance in traditional Green American coolants.

These Organic Acid technologies or OAT Antifreeze products were introduced to America from Europe. They have a longer working life than the standard Green Antifreeze products. This is because of the inhibitors that they added before the liquid started to break down. It’s important to note that organic acid antifreeze should never be used on older vehicles that have traditional copper-and-brass radiators, only aluminum or plastic ones.

Understanding The Damages of Pure Antifreeze In Cars


Here at MyWaterEarth&Sky, we’ve chatted before about the risks of using pure antifreeze as a coolant in your car and today we’re diving a bit deeper. So, grab a seat, and let’s break down the damages of straight antifreeze in cars or as some of you like to say the coolant. Money talks, right? So, let’s save those pennies and your engines!

Often, you might hear at the top shop around the block, “I put straight antifreeze in my car all the time, it’s totally cool.” However, just because Tom, Dick, or Harry does it, doesn’t make it a golden rule. Using pure antifreeze isn’t the way to go. Trust me, I don’t just say stuff, I’ve got reasons, and they’re pretty darn convincing!

Antifreeze is amazing stuff, no doubt. Warms your engine up in winter and cools it down in summer. A marvel, really! But straight antifreeze isn’t the best thing for your engine. It’s more like that kid who seems cool but is not trustworthy. So let’s get to the ‘not’ part, shall we?

Using pure antifreeze can play tricks on your car. It’s super thick, and guess what, it won’t circulate through the engine as effectively as a mix of antifreeze and water (your faithful coolant). If it ain’t circulating, it ain’t cooling – simple, right? Pure antifreeze also has, like, half the heat absorption capacity of water, meaning your engine would run a lot hotter than it should. That’s a no-no, my friends! What’s more, using this stuff straight up can cause your beautiful, hardworking engine to turn on you.

It’s essential to understand that what’s usually recommended is a 50/50 mix of antifreeze and water. The coolant is what you want to keep your car purring like a contented kitten, not a hissing cat. Coolant keeps your engine happy, keeps it cool, and keeps it running at its best. Plus, it helps protect against corrosion, so it’s a win-win situation, right?

To wrap up, I hope you now get why I keep shaking my head at this pure antifreeze idea. It’s not a smart choice for your car. ‘Straight’ does not equal ‘best’ here, trust me. Used properly, antifreeze is amazing- but it’s not meant to be used just as it comes out of the bottle. It needs its buddy, water.

Together they make the perfect team- coolant. So, friends, keep your cars happy and stick to the coolant! And remember, you can always count on MyWaterEarth&Sky for your latest and greatest car maintenance tips. Stay tuned till next time!
