Antifreeze versus Coolant? (The answer is found)

Though coolant and antifreeze are often used interchangeably, they aren’t the same. Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling systems of all “water-cooled” vehicles.

  • Antifreeze is the substance added to water to alter its boiling and freezing points. On the other hand, coolant is a mixture of water and antifreeze. You also learn that there are coolants that do not use water.

Do I need antifreeze or coolant?

The key difference in terms is simple; the engine needs to be cooled to the correct optimum temperature all year round, even in winter. So the engine needs ‘coolant’ 365 days a year. During cold weather, the coolant needs to have ‘antifreeze’ properties in it to prevent it from freezing.

Can I put antifreeze in coolant?

Adding antifreeze on top offers an extra layer of protection in the winter. As a result, you can use coolant without antifreeze, but not the other way around. You can put antifreeze straight into the coolant tank but there may be a leak if you need to top up a lot.

Is antifreeze the same as coolant?

Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it’s important to know what variety is right for your car or truck.

How do I know if my car needs antifreeze?

5 Signs That Your Vehicle Needs An Antifreeze/Coolant Service

  1. The temperature gauge reads hotter than normal when the engine is running.
  2. Antifreeze leaks and puddles beneath your vehicle (orange or green fluid)
  3. A grinding noise is coming from under the hood of your car.

What happens if you use straight antifreeze?

Using pure antifreeze inside your vehicle’s cooling system causes that system to lose about 35 percent of its ability to transfer heat versus a proper mixture of antifreeze and water. Otherwise, your engine could overheat and cause your vehicle to break down.

What is the benefit of antifreeze?

Prevents Engine Damage In cooler climates, antifreeze prevents water in the engine from freezing and damaging essential engine parts. Antifreeze coolant alleviates engine stressors, such as overheating and cracking caused by higher air temperatures and combustion heat created in the engine core itself.

Do modern cars need antifreeze?

Why do I need antifreeze? Modern car cooling systems are smaller, with higher operating temperatures and pressures than in the past. If you don’t use antifreeze, you could suffer serious damage to your car’s radiator and other components if the water freezes or overheats.

Do cars still need antifreeze?

The answer: nothing good. Coolant circulates through your car and extracts heat from various components, keeping their operating temperature within normal parameters. Without coolant, there’s nothing to extract this heat, and these parts quickly overheat and break down.

How long does antifreeze last in a vehicle?

Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.

Can you use any antifreeze in any car?

There are lots of different types of antifreeze and it’s crucial to understand that there is no single antifreeze that’s suitable for all makes and models. The best thing to do is to always use the antifreeze that’s recommended by your car manufacturer.

Does antifreeze prevent rust?

It provides protection from rust and corrosion and does not harm rubber hoses and plastics. Antifreeze should not corrode metal parts, attack rubber, become viscous at low temperatures, or evaporate readily at the ordinary engine operating temperature.

How much does antifreeze cost?

The cost of a coolant or antifreeze change will depend on the type and size of your vehicle. On average you can expect to pay between $100 and $200 for a standard coolant change.

A colored liquid that is blended with water to assist regulate your engine’s temperature when it is exposed to high temperatures is known as antifreeze or engine coolant. In order to maintain a consistent operating temperature throughout the engine block, coolant is injected throughout the engine block as the weather outside varies from hot to cold. Antifreeze, on the other hand, does more than only regulate temperature. Preventing corrosion by maintaining adequate fluid levels is another benefit of doing so.

How Does Engine Coolant Work?

A 50/50 mixture of engine coolant and water is put into the appropriate reservoir in your engine, and the mixture is allowed to cool. In order to manage and maintain an appropriate operating temperature under severe hot or cold weather conditions, the chemical ethylene glycol is used as a basis to make a liquid that is pushed through your car’s engine.

What Makes Each Antifreeze Type Different?

A mixture of engine coolant and water is prepared and placed into the appropriate reservoir in your engine. The mixture is typically 50/50 in ratio. It is made possible by the chemical ethylene glycol acting as a basis to form a liquid that is pushed through your car’s engine to adjust and maintain an appropriate operating temperature under severe hot or cold weather conditions.

How Often Does My Car Need New Coolant?

A mixture of engine coolant and water is prepared and placed into the appropriate reservoir in your engine. The mixture is normally 50/50 in ratio. In very hot or cold weather conditions, ethylene glycol is used as a basis to make a liquid that is pumped through your car’s engine to control and maintain an appropriate operating temperature.

Your Antifreeze/Coolant Questions Answered

Although it may appear that antifreeze should be used in cold weather and coolant should be used in warm weather, antifreeze and coolant are two concepts that are identical with one another. What coolant your automobile uses does not matter; determining the best one for your vehicle and the proper amount to maintain in the tank in both cold and warm conditions are crucial to the operation of your engine’s cooling system. Allow us to take a moment to address some of the most often asked concerns regarding the fluid that maintains your car’s engine operating at precisely the proper temperature before you fill up your coolant tank.

What Kind of Engine CoolantShould I Use?

Antifreeze may be separated into two types: IAT antifreeze and OAT antifreeze. IAT antifreeze is the more common form. It has been nearly 70 years since IAT (inorganic acid technology) antifreeze became the international norm. It is the green antifreeze of the past. During the late 1980s, when automobiles began to use more and more aluminum components in their engines, the necessity to develop a stronger, longer-lasting coolant resulted in the development of OAT (organic acid technology) antifreeze.

Many producers produced their own mix of OAT antifreeze that had less silicates and phosphates and, as a result, developed a specific hue of antifreeze to distinguish it from the competition’s antifreeze.

One of the most prevalent and long-lasting coolants of this sort is DEX COOL®, which was created by General Motors (GM) in the late 1980s and has been in use ever since that time.

Of course, there are speciality formulas available, and being aware of the possibilities available might make your automobile ownership experience a whole lot more enjoyable overall. A few instances of special versions that you could find beneficial in the correct situation are as follows:

  • Many manufacturers provide cold weather protection that can withstand temperatures as low as -34 degrees. The use of non-toxic antifreeze for animals is also becoming increasingly common. Manufacturers of coolants for excessive heat provide formulae that are comparable to those used for cold weather.

The final decision on which antifreeze to use is mostly based on your requirements, as long as you select a formula that is suitable with your vehicle.

What Kind of CoolantDoes My Car Need?

If you are still unclear about which coolant to use, the best place to start is by purchasing the coolant advised by your owner’s handbook. If you go through the brand’s variations, you will most likely come across the versions described above. If you require a specific formula, the handbook is also your greatest resource for determining the formula you require. AutoZone can assist you if you do not know where your manual is and you want assistance: either ask a shop staff for assistance or use ourcoolant search to determine which type of coolant is appropriate for your vehicle’s make and model.

Are Basic Antifreeze Formulasthe Same?

Almost every antifreeze used by original equipment manufacturers (OE) designers is 95 percent ethylene glycol, but the additives used vary greatly from manufacturer to manufacturer, giving each brand and version its own set of features and characteristics. Following the guidelines include using the antifreeze that performed the best under controlled settings, which is the standard procedure.

How Often Do I Need ToChange My Coolant?

Full coolant replacement is normally advised by manufacturers every three to five years or 100,000 to 150,000 miles, depending on the model, however these intervals can be shorter for older autos in some cases. OAT antifreeze was created with a substantially longer shelf life in mind than IAT antifreeze was. It is possible to determine the specific gravity and color of your coolant to determine if it is time to change it. You’ll need a special kit if you want to do it yourself. The majority of the time, coolant lasts longer than the manufacturer’s estimate, although it might fail prematurely, resulting in decreased performance.

Longer life expectancies can be obtained by the use of extended life types, with some formulae advertising life expectancies of up to five years in some cases.

Do I Need ToAdd Coolant Regularly?

No, not in an ideal world. Theoretically, your cooling system should be self-contained, with the same fluid being reused until it deteriorates to the point where it has to be replaced. It is more common, though, for things to operate in this way: the system has an overflow tank for a reason, and it occasionally overflows. As long as the level is not excessively high, even at regular temperatures, you should be alright. If you’re in intense heat and temps rise only a few degrees beyond ideal, it’s possible that you’ll lose coolant that you regularly rely on as a result of volume changes.

When a vehicle is brand new, most individuals will find that they only need to replenish coolant on a rare occasion.

However, as automobiles age, many of their cooling systems become less efficient. This process may be slowed down by preventive maintenance and excellent care in general, and a complete vehicle restoration can turn the clock back if you are determined to keeping a vehicle in its original condition.

Does AntifreezeDo Anything Else?

Yes! Antifreeze does more than just keep your car’s engine cool and prevent it from freezing; it also works as a corrosion-resistant liquid, whereas pure water would erode engine parts and fail to properly lubricate the moving water pump, among other things. That is why you should always use the combination indicated in your owner’s handbook, and why it is critical to maintain ideal coolant levels.

The Car Is Losing Antifreeze?Is There a Leak?

There are a variety of reasons why a vehicle’s antifreeze may be depleted, including spillage and evaporation if the cap is missing. Whether you notice that you are losing a consistent amount of coolant, look closely around the engine compartment for drips and leaks, and locate the front of the water pump to see if the water pump itself is dripping. The use of a drop cloth under the car can aid in pinpointing the location of the leak since the antifreeze drips will leave a stain where the cloth is placed.

In any case, the system should be thoroughly pressure-tested and checked for leaks, including a blown head gasket or an internal rupture.

Don’t forget to follow all of the manufacturer’s recommendations for replacement, including the replacement of all hoses and valves at the manufacturer’s suggested periods.

Most importantly, updating the system will assist it in maintaining the efficiency that new automobiles have, making it simpler to ask your engine to function at a higher level for a longer period of time.

Is coolant the same as antifreeze?

Extremely hot or cold weather may have a detrimental effect on your vehicle, so it’s a good idea to brush up on your knowledge of how to properly maintain your engine’s cooling system when the seasons change. You will need to use antifreeze and coolant in order to keep your cooling system operating properly. The meanings of the phrases coolant and antifreeze, as well as how they vary from one another, might be unclear, especially because many people use the terms interchangeably. Is coolant and antifreeze the same thing?

Is antifreezecoolant?

Is antifreeze a type of coolant? Antifreeze and engine coolant are quite similar, yet they are not the same thing. Unlike antifreeze, which is a concentrated, glycol-based liquid that must be diluted with water before use, coolant may be used directly without diluting with water. A pre-mixed engine coolant, a ready-to-use combination of antifreeze and water, is also available for purchase as an alternative. Antifreeze, which is mostly composed of ethylene glycol, is used in a car’s cooling system to ensure that the engine continues to run smoothly even in the most extreme sub-zero temperatures.

It also serves to lubricate the water pump and prevent corrosion from occurring.

This is due to the fact that antifreeze works best as a diluted liquid (therefore acting as a coolant) when dealing with extremely high temperatures.

Antifreeze does not have an expiration date, but the additives that prevent engine corrosion are.

Additionally, because ethylene glycol is hazardous to both people and animals, it is important to carefully follow the manufacturer’s safety recommendations and disposal instructions while using this product.

Mixingantifreeze and coolant

It is not possible to combine pink and blue antifreeze. Stick to the coolant combination advised by your vehicle’s manufacturer to avoid a malfunctioning cooling system and engine damage.

Can you mix the sametype of coolants? ​​​​​​​

Always re-fill your car’s coolant reservoir with the same kind and brand of fluid. Whenever in doubt, it’s advisable to heed the manufacturer’s advice or consult your local garage for assistance. We do not recommend that you combine coolants. A common misconception is that the color of the liquid solution can be used to identify the type of coolant. However, because multiple colors can be used to indicate the same type of coolant, we do not recommend using the color of the liquid solution as an indicator of coolant type as a general rule.

You may also learn more about what coolant and antifreeze are.

The Basic of Antifreeze and Why Your Car Needs It

In your radiator, you’ll find a clear, colored liquid called antifreeze. This antifreeze, often known as coolant, is available in several distinct colors to suit your needs. It is used for a variety of reasons, including: Using antifreeze in your radiator and engine helps to prevent the water in your system from freezing in cold climates. At addition, antifreeze prevents the same water from boiling over in extremely high conditions. Antifreeze also acts as a lubricant for the moving parts with which it comes into contact, such as the water pump, when it freezes.

If properly mixed (a 50/50 mix of antifreeze and water is ideal), ethylene glycol can prevent your radiator fluid from freezing even in temperatures as low as 30 degrees below zero and also prevent those fluids from boiling in temperatures as high as 275 degrees Fahrenheit, according to the manufacturer.

Having a low level of antifreeze in your engine can cause it to overheat or freeze, which can result in significant financial loss in the long term.

How To Check Antifreeze Levels?

In your radiator, you’ll find antifreeze, which is a clear colored liquid. This antifreeze, often known as coolant, is available in several distinct colors to suit your preference. You may use it to do a variety of tasks. Water in your radiator and engine does not freeze when it is exposed to freezing temperatures thanks to antifreeze. In addition, antifreeze prevents the same water from boiling over in extremely hot weather conditions. Additionally, antifreeze acts as a lubricant for the moving parts with which it comes into contact, such as those found in the water pump.

Even in temperatures as low as 30 degrees below zero, ethylene glycol can prevent your radiator fluid from freezing (a 50/50 mix of antifreeze and water is optimal).

Keep an eye on the antifreeze level in your car at all times to ensure it is operating properly. It is important to check your antifreeze levels every 2 to 3 months since a low level can cause your engine to overheat or freeze up, resulting in costly repairs down the road.


If you discover that you need to add extra liquid, wait until the engine has completely cooled before continuing. By doing so, you eliminate the chance of being burnt or having your engine block cracked. Even if you meet difficulty on the side of the road and only need to add water until you can go to a repair shop, you should wait until your engine has cooled before proceeding. Additionally, do not open the lids on either the coolant reservoir or the radiator while the engine is running, even if you are merely checking the coolant levels.

Additional considerations about antifreeze: It is necessary to fully cleanse your cooling system and replace the coolant with a new 50/50 mixture if your coolant appears colorless, rusted, or has foreign items floating about.

To inspect for internal head gasket leakage, they will require specific gear and training.

If they are leaking, bulging, or cracked, they should be replaced immediately.

Antifreeze: The Ultimate Guide

In preparation for the onset of cold weather, it is necessary to inspect your vehicle to ensure that it is properly equipped for the drop in temperature. Due to the large number of exterior components that must be examined, such as the lights, windshield wipers, and tires, it’s easy to overlook the importance of checking the cooling system of your vehicle. Failure to use the proper coolant or the correct proportion of antifreeze might easily result in major engine problems in the future. So, what exactly is antifreeze, and how can we use it correctly to keep our automobiles safe from the elements?

  • In your car’s cooling system, antifreeze is a glycol-based fluid that is generally composed of ethylene glycol or propylene glycol.
  • After replacing glycerol as the primary antifreeze in the marketplace in 1926, ethylene glycol would still be the undisputed champion if not for its exceedingly poisonous characteristics.
  • Aside from glycol, antifreeze mixes contain pH buffers, which help to maintain the alkalinity of the solution, as well as anti-corrosive substances, which help to prevent the corrosion of the metallic components of the cooling system, which can lead to corrosion.
  • Each and every internal combustion engine, including the one that resides beneath the hood of your automobile, generates a significant quantity of heat.
  • This might result in catastrophic engine failure if the temperature does not stabilize.

Because of environmental constraints, air-cooled engines have been out of favor for a long time. As a result, liquid-cooled engines are now the only alternatives accessible, which resulted in the development of antifreeze as a result.

1. Where water fails, antifreeze works:

Despite the fact that water is a good engine coolant, it begins to boil around 212 degrees F, which is a temperature that is readily attained in a running engine. The boiling point of water is reached when it turns into steam, which increases pressure on the radiator and its hoses. Additionally, when steam is expelled from the system, the water level lowers dramatically, increasing the risk of overheating the system. If that isn’t enough, water begins to freeze at 32 degrees Fahrenheit. Consequently, in colder climates, the power with which water freezes can cause hoses and radiators to burst, especially in the presence of ice.

2. Dual protection with antifreeze:

On the one hand, antifreeze lowers the freezing point of the water in the coolant mixture, preventing it from freezing inside the radiator, the water pump, and the hoses. On the other hand, antifreeze lowers the freezing point of the water in the coolant mixture, preventing it from freezing inside the radiator, the water pump, and the hoses. On the other hand, it raises the boiling point of the water in the coolant mix, allowing it to chill the air more effectively than before. As a result, utilizing coolant is the most effective method of maintaining a consistent operating temperature in your vehicle.

3. So much more than just temperature control:

An further difficulty associated with water is the fact that it may cause corrosion of all metallic components in the engine, including iron and aluminum parts, very fast and severely. In part, this deterioration is prevented by the presence of anticorrosive ingredients in antifreeze blends. Furthermore, these solutions contain components that slow down organic contamination or bacterial development, which would occur much more quickly if simply water were employed as the coolant.

The difference between antifreeze and coolant

By now, you may have noticed that the phrases “antifreeze” and “coolant,” as well as other similar terminology, have been used interchangeably throughout this text. As previously stated, cooling fluid (also known as coolant) is essentially a pre-mixed combination of antifreeze and water, often in the ratio of 50-50 or 70-30. This is because the coolant already includes water, thus there is no need to dilute these items prior to use. Antifreeze, on the other hand, must first be combined with water before it can be used.

As an added convenience, the different varieties of antifreeze/coolant are color-coded to make finding the right one easier.

The different types of antifreeze

When it comes to the primary component, antifreeze mixtures are available in two varieties: the traditional ethylene glycol-based version and the non-toxic propylene glycol-based version. However, this is not the most significant distinction. The fundamental difference between antifreeze solutions is the anticorrosive elements that are included in their formulation. Up until the mid-nineties, antifreeze blends based on ethylene glycol and vivid green in color were the standard. However, with the introduction of newer automobiles and the advancement of engine components, the demand for more effective antifreeze solutions that provide better protection has increased.

The goal with each of them is to handle the individual requirements of different engines and their components.

When it comes to choosing the fluids for your car, it’s always a good idea to examine your owner’s handbook first to see what the manufacturer of your vehicle advises for your vehicle.

Why is antifreeze different colors?

In their colorless condition, both ethylene and propylene glycol are indistinguishable from water. Adding anti-corrosive chemicals and other additions would make no difference to their colorlessness. To make it easier to distinguish one type of antifreeze solution from another, producers color these mixtures in order to accommodate the wide variety of antifreeze solutions available. Generally speaking, coolants are classified into three categories:

1. Inorganic acid formula (IAT):

For all automobiles made before the mid-nineties, this basic bright green coolant is still used in all older cars, including all domestic vehicles from Ford, General Motors, and Chrysler. These low-silicate, typical antifreeze solutions, which are made by mixing phosphates and a small quantity of silicate with glycol, also contain supplementary coolant additives (SCA) to protect the engine liner against corrosion. In reality, it is the SCA that are the first components of the coolant to become depleted of their effectiveness.

2. Organic acid technology (OAT):

These coolants became commonplace in automobiles in the late 1990s and are currently in use in many modern vehicles all around the world. Despite the fact that they are free of phosphates and silicates, OAT coolants have corrosion resistance that is comparable to that of green antifreeze mixtures. However, because the anti-corrosive chemicals in these solutions are slow-acting, the product has a longer shelf life than other alternatives. Additionally, it is particularly developed to provide anti-corrosive protection to the aluminum and nylon components used in newer model automobiles.

The fact that OAT products, unlike IAT coolants, have propylene glycol as their foundation means that they are less toxic to pets, children, and the environment if there is a spill or boil-over is another significant distinction.

Most General Motors vehicles made after 1995, as well as Audi, Honda, Jaguar, Kia, Land Rover, Mazda, Nissan, Porsche, Saab, Toyota and Volkswagen vehicles manufactured between 1996 and 2001, are equipped with these coolants that are commercially accessible.

3. Hybrid organic acid technology (HOAT):

As their name implies, these coolants combine the greatest characteristics of IAT and OAT solutions to provide outstanding corrosion protection for aluminum parts and rustproofing for iron components, respectively. HOAT products are often coloured yellow or orange, although they are also available in a variety of other colors, including pink, purple, and blue. “Global” HOAT items are typically referred to as such, and you will almost always see a sticker on the package that states something to the effect of “Meets or exceeds G-05 requirements.” It is necessary to replace these antifreeze mixtures every 5 years and they are prescribed for the majority of automobiles made after 2002 by manufacturers such as Audi BMW Chrysler Ford Mercedes-Benz Saab Volvo and VW.

According to what you may have seen, the color of the coolant is not a good indicator of the sort of coolant you are getting.

As a result, carefully check the bottle’s description and ensure that it corresponds to the coolant indicated in your vehicle’s owner’s handbook.

rather of putting yourself through the hassle of verifying with a local mechanic or repair business Despite the fact that it will cost you a few dollars, a comprehensive engine overhaul will almost probably be less expensive than this procedure.

Can you mix antifreeze colors?

Shortly put, you cannot combine several types of antifreeze mixtures together. As a matter of fact, HOAT coolants are available in at least three varieties (Silicated HOAT, Phosphated HOAT, and Phosphate-free HOAT), and you should avoid combining even the variants, much alone the primary classes, of coolants. A chemical reaction will occur in the reservoir if the green is mixed with the orange or the orange is mixed with the blue/yellow, for example. In the reservoir and radiator, a brown, gelatinous sludge forms, which can eventually entirely obstruct the cooling system’s ability to function.

Where do you put antifreeze?

Under the hood, the antifreeze reservoir is quite straightforward to identify. It is a semitransparent, white container constructed of thick plastic that is semitransparent in appearance. It is normally located on the side of the engine and is protected by a plastic or metal cap. Additionally, you may see a warning mark on the top of the cap, which indicates that you should avoid opening the lid while the engine is running or when it is hot. In addition, the reservoir contains a colorful liquid, so if you can’t locate the cap, check for the reservoir first and then follow the hoses to the radiator/cap till you do.

If you accidentally dump coolant into your engine oil or washer fluid tank, it may be a very expensive mistake.

How often should you change your antifreeze?

Antifreeze, whether it’s formed of ethylene glycol or propylene glycol, has no expiration date as a chemical compound. However, with time, the anti-corrosive properties of the product degrade, and at that point, a replacement is required. As previously noted, IAT coolants have the lowest lifespan of around 2 years, but both OAT and HOAT coolants have a lifespan of approximately 5 years. However, even before you reach these points, your vehicle may begin to give you indications that it need a coolant replacement.

  1. Typically, this is caused by a coolant leak, which should be investigated.
  2. If the needle is moving either upward or downward, it indicates that the cooling system has been damaged.
  3. Keep in mind that such puddles must be cleaned up before you can proceed with any other activities since they are extremely harmful to both humans and animals (more on this coming up).
  4. Heater not functioning: The heater uses the same coolant as the vehicle’s engine, hence it is not operating.
  5. Even if none of these indicators are present, it is a good idea to check the status of the coolant on a regular basis using chemical strips.

These are inexpensive and simple to use, and are not unlike to a simple litmus test in terms of functionality. The coolant should be changed if the test results suggest that the coolant has become acidic.

How often should you check your antifreeze levels?

The answer to this question will differ depending on who you speak with. Coolant levels should be checked every time you refuel or at least once every two weeks, according to the majority of OEMs and aftermarket coolant producers. Ideally, you should check the coolant level once every six months, which means before the summer and before the winter seasons. In most cases, checking the coolant level in the reservoir will take no more than a minute or two. If you look attentively, you will see that the maximum and minimum level markers are located on the reservoir’s body, to the side.

If the fluid level is below the maximum line, it is possible that this is due to natural and slow loss.

You will need to top up the reservoir and check it on a regular basis for a few days if the level has dropped below the minimum line, though.

How to dispose of antifreeze?

All kinds of exposure to ethylene glycol antifreeze are extremely harmful to the body (fumes, skin contact, and ingestion). In addition, when coolants move through the engine of the car, they pick up heavy metal pollution from the air. If there is a boil-over of the coolant in the reservoir or radiator, a spill of unused antifreeze, or a leak of used coolant, you must exercise extreme caution in these situations. For this reason, it is strongly suggested that you get your cooling system flushed by a repair business rather than flushing antifreeze down the drain/sink or toilet or pouring it into the soil.

  • If you do decide to carry out the procedure at home, make sure to wear protective garments to prevent the fluid from getting into touch with your skin while doing so.
  • In the event that coolant is combined with gas or engine oil, it is considered polluted and hence cannot be recycled at a standard recycling facility.
  • On the website, there is a recycling locator that may be used to locate the nearest recycling facility.
  • And with that, you now understand what antifreeze is, as well as nearly everything else about these remedies.
  • Using too much or too little antifreeze in the coolant mixture will not help you achieve your objectives.
  • Antifreeze to water is best used in a 50-50 ratio year-round, but in the winter, it may be necessary to raise the ratio to 70-30 (antifreeze to water) (70 percent antifreeze).

In addition, even if you are in the middle of nowhere and you run out of coolant, get your vehicle the coolant it requires as quickly as you can to avoid irreversible damage to the engine and other parts of the car.

Antifreeze vs. Coolant: Radiator Fluid

Let’s take a quick pop quiz (sorry for the inconvenience): is it true or incorrect that antifreeze and coolant are the same thing? The answer is.IT’S TRUE! To make matters simpler, these items are collectively referred to as radiator fluid; therefore, if in doubt, simply refer to them by that name. It’s time to get your car ready for winter driving conditions, which will include cold temperatures, salt-coated roads, and slippery driving conditions. Many individuals are aware that their radiator requires antifreeze or coolant when the temperature outside is below freezing.

And you are aware that this fluid is essential for keeping your vehicle’s engine in excellent operating order and for preventing it from freezing or overheating in any weather conditions.


Radiator fluid is essentially a blend of chemicals that improves the anti-freezing and anti-overheating qualities of the vehicle, as well as corrosion inhibitors, among other things. It serves as a heat transfer medium for the engine, warming the engine block when it is cold and taking heat away from components when the engine is hot. It is made of aluminum. The cooling system operates in a closed loop, with water passing through the engine and heater core before returning to the radiator and repeating the process all over once again.

These inhibitors also safeguard the engine and cooling system against the accumulation of any scale, rust, or pollutants that could impair its function over time.


It is critical to select the proper radiator fluid for your car because there are many different varieties, each of which is characterized by its formulation, such as the type of corrosion inhibitor that is included in the mix. Organic corrosion inhibitors, inorganic corrosion inhibitors, and hybrid corrosion inhibitors are all possible. Many of these formulas function by covering the interior of engine components with a layer of protective film, which decreases friction, cleans the components, and prevents deposits from forming on the surfaces of the components.

Radiator fluids should not be mixed since this can result in the formation of a gel byproduct that can block the cooling system passageways within your engine, causing the same overheating or freezing that radiator fluid is intended to prevent.

As a result, if you’re in doubt, double-check to be sure you’re not mixing things up.


Checking the coolant level in most automobiles may be accomplished by peering inside the radiator fluid reservoir tank. Wait until your engine is completely cold before opening the hood of your car and inspecting the coolant reservoir (which is normally a tiny clear tank with MAX/MINOR FULL/ADD lines written on the side) for a cap with the words “engine coolant” or “antifreeze” imprinted on the top. There should be visible radiator fluid in the tank, with the fluid level somewhere between the two marks on the tank.

A hazy or milky appearance in the radiator fluid may indicate probable contamination with a petroleum product, such as engine oil or transmission fluid, and should be investigated.


It is necessary to top off the radiatorfluid whenever the level in the reservoir falls below the minimum and maximum levels recommended for your tank. Check to ensure that you have the right radiator fluid and that you have mixed or diluted it according to the manufacturer’s instructions. After you’ve created your radiator fluid, unscrew the cover from the reservoir tank and slowly pour the mixture into the tank until it reaches the MAX/FULL line. Install the cap by rotating it until it snaps firmly into place on the nozzle.

After you’ve removed the radiator cap, slowly pour in the radiator fluid, one drop at a time.

Continue to pour until you reach the bottom of the radiator filler neck, and then replace the radiator cap to complete the process.


It’s important to remember that this isn’t about antifreeze versus coolant because they are interchangeable and can both be referred to as radiator fluid in some cases. It is recommended to change radiator fluid on a regular basis, depending on the kind of fluid used, the amount of kilometers driven, and the age of the fluid. By consulting your vehicle’s owner’s handbook, you may determine if the manufacturer’s guidelines are followed. It is recommended that you physically monitor your radiator fluid level as the season changes (particularly in preparation of the more dramatic summer and winter temperature variations) and that you flush and replace your coolant according to the manufacturer’s instructions when the season changes.

This ensures that your vehicle receives the proper type and amount of radiator fluid to perform at its best.

Aside from that, Jiffy Lube will test your vehicle’s cooling system and determine whether or not it requires replacement radiator fluid, as well as properly dispose of your old radiator fluid.

Bring it to Jiffy Lube regardless of whether it’s hot, cold, warm, or cool. Ensure that your antifreeze/coolant is fully stocked.

What is Antifreeze? How Does it Work?

It’s important to remember that this isn’t about antifreeze versus coolant because they are interchangeable and can both be referred to as radiator fluid in some circumstances. A regular radiator fluid replacement should be performed according to the type of radiator fluid used, how many miles were driven, and when the fluid was first installed. If you have a look at the owner’s handbook for your car, you can see what the manufacturer recommends. When the seasons change (particularly in preparation of the more extreme summer and winter temperature swings), it is recommended that you physically verify your radiator fluid level and flush and replenish your coolant according to the manufacturer’s instructions.

Isn’t that amazing?!

The antifreeze in your engine and radiator protects the water in them from boiling over when it’s hot outside. It is effective with liquids at temperatures of up to 275 degrees Fahrenheit, according to the manufacturer. The use of antifreeze, when temperatures drop, keeps this same water from freezing, even at temperatures as low as 30 degrees below zero.

It does this by reducing friction, which can cause harm to your engine if not controlled properly.

The aluminum cylinder heads used in the majority of engines are particularly sensitive to corrosion, making the use of adequate antifreeze essential for the health and durability of your car.

What Is in Antifreeze?

Antifreeze is generally composed of either ethylene glycol or propylene glycol as the primary constituent. Antifreeze may also contain additives, such as silicates, nitrates, azoles, or borates, which are used to prevent oxidation and corrosion in the engine compartment. The amount of these additives in the overall solution is generally less than 10 percent of the total solution. Antifreeze and water are mixed in equal parts in automobiles. Some antifreeze, on the other hand, is pre-mixed and already includes the correct amount of water.

Important to remember is that antifreeze is hazardous and should always be kept out of the reach of children and animals. If you spill antifreeze, wipe it up as soon as possible to avoid it being consumed accidentally.

Where Does Antifreeze Go in a Car?

It is customary for antifreeze to be added to the coolant reservoir in your car. The antifreeze in certain older automobiles is forced into the radiator since they do not include a coolant reservoir. Whether you’re looking for the coolant reservoir or the radiator cap, you’ll find them both under the hood, though the specific location will vary from vehicle to vehicle. Consult your vehicle’s owner’s handbook for specific instructions on how to locate the coolant reservoir that contains your antifreeze solution.

What Color Is Antifreeze?

Antifreeze is usually colored, however the color varies from one product to the next depending on the manufacturer. It is possible to find antifreeze in a variety of colors, including green, blue, pink, red, orange, and yellow. But your antifreeze should never be rusty in appearance, and there should be no particles floating about in it. If you detect any of these symptoms, it’s time to cleanse the cooling system and replace the antifreeze with fresh.

What’s the Difference Between Antifreeze and Coolant?

When it comes to vehicle specialists, even the phrases antifreeze and coolant are frequently used interchangeably. There is, however, a tiny distinction between the two. Coolant is a technical term that refers to a ready-to-use combination of antifreeze and water that is installed in your car. It is the ethylene glycol or propylene glycol component of this combination that acts as an antifreeze. As a result, an antifreeze product that does not include any water is referred to as pure antifreeze, whereas a coolant product that contains water is referred to as coolant.

Antifreeze is a term used to describe any chemical compound that lowers the freezing point of water.

This distinction is really minor, and the majority of people will understand you regardless of whether you refer to the substance used to cool the engine in your car as antifreeze or coolant.

How Do I Know if I Need More Antifreeze?

Inspecting your vehicle’s coolant reservoir or radiator can allow you to determine the amount of antifreeze present. You should be able to see a transparent plastic tank with a clearly indicated fill line at the bottom. Make sure your car is parked on a flat, level area and that the engine is completely cold before taking the antifreeze level reading to get the most accurate reading. Generally speaking, you should replace the coolant in your car every 30,000 to 60,000 miles driven. Your car’s owner’s handbook should provide you with additional precise information regarding the brand and model of your vehicle.

If you have any concerns regarding the coolant in your automobile, you should consult with a professional. You may have a problem with your antifreeze or cooling system if you observe any of the following symptoms in addition to those listed above.

  • A coating of greasy or sludgy antifreeze on top of the antifreeze Coolant concentrations that are exceedingly low Radiator hoses that have cracked
  • Antifreeze that is colorless or rust-colored
  • In the antifreeze, there are particles floating about.

The presence of any of these symptoms indicates that you should take your car to an expert for an inspection. A trustworthy mechanic can explain what’s going on and offer the most appropriate cooling system repair for your situation. It is important not to disregard these difficulties since doing so might result in irreversible harm to your engine.

How Do I Add Antifreeze to My Vehicle?

The presence of any of these symptoms indicates that you should get your car examined by a qualified mechanic. A reputable mechanic can inform you of the situation and make recommendations for the best cooling system repair. Keep these problems under consideration since they might cause irreversible harm to your engine if left unattended.

  1. Place the car on level ground and allow it to cool completely before driving away. As an extra safety precaution, engage the parking brake on your car. It is necessary to check the label on your antifreeze to decide whether it is necessary to combine it with water. It is possible to inflict major harm to your vehicle’s radiator by adding unmixed antifreeze to the system. When necessary, dilute the antifreeze with water. The coolant reservoir should be opened and the liquid should be added until it reaches the fill line on the outside of the tank. When you’re finished, tighten the cap on the reservoir to prevent leakage.

The Three Main Ingredients In Coolant

Coolant is made up of three primary components: Generally speaking, coolant is composed of three primary components:

1. Water

Among other interesting facts, some automobile owners in the 1930s used simply water to cool their motors. It’s hardly surprising, considering water is the most effective method of cooling the engine. The question you could be asking is, “If water is the most effective method of cooling the engine, then why does coolant exist?” Just because water is the most effective method of cooling the engine does not imply that it is beneficial to the engine. Water has a high corrosive potential, which is terrible news for the components within your engine.

However, it was still not satisfactory since it continued to generate rust.

We are well aware that ice cannot be moved through an engine’s internal combustion system.

As a result, individuals set out to create a failsafe method that would do the following:

  • It wouldn’t corrode the internal engine components in any way
  • Wouldn’t freeze even in the coldest of temps
  • This ensured that the engine would not overheat and generate steam pressure. Could keep the engine cool under any circumstances

They eventually discovered a means to transport water to a higher level, and they were surprised to see that it was so simple. What is the solution? All you have to do is add antifreeze.

2. Antifreeze

Ethylene glycol is referred to as antifreeze in some circles. Coolant contains antifreeze because it reduces the freezing point of the coolant and raises the boiling point of the coolant.

In other words, antifreeze makes it feasible for the coolant to remain liquid at freezing temperatures and to remain solid at high temperatures without freezing or dissipating into steam. The following is the chemical makeup of antifreeze:

  • More than 90% ethylene glycol (in most cases, depending on the manufacturer)
  • More than 90% ethylene glycol The following compounds are exclusive to the manufacturer and are used to protect engine components (such as the water pump) against rust and corrosion:
  • Phosphates (which prevent iron from rusting)
  • Silicates (which prevent aluminum from rusting)
  • And other compounds. A solvent that is used to emulsify the liquids.

3. Dye

Have you ever noticed that coolant is available in a variety of colors? There is a valid explanation for this. Coolant is usually colorless when it first comes out of the factory, but the dye is added afterwards by the producer. Depending on the hue, each coolant symbolizes a different type of coolant. The following are some of the most popular coolant colors: Please keep in mind that you should never combine various coolants in the same container! This article does an excellent job of explaining why.

We would much appreciate hearing your thoughts!

What Is Antifreeze?

In the case of water-based liquids, antifreeze can be used to reduce the freezing point – and, conversely, to raise the boiling point — by increasing the boiling point. The automobile sector, for example, uses antifreeze in the form of ethylene glycol to mix with water as the engine coolant in cars, which protects the engine from freezing in cold weather. It is possible that if only a little amount of antifreeze is applied, and water freezes in the engine, the engine will experience significant internal pressure as a result of expansion, resulting in serious engine damage.

Caring for your car’s coolant is essential!

What is Antifreeze Made Of?

Antifreeze may be created by mixing any of the four major ingredients listed above with water: methanol, glycerol, ethylene glycol, and propylene glycol. Methanol, glycerol, and ethylene glycol are the most common. Each agent has its own set of advantages and disadvantages, which vary depending on how you want to employ it.

  • In addition to being a highly flammable and hazardous liquid, methanol is also utilized in automobile windscreen washer fluid and de-icers. A non-toxic substance that can resist higher temperatures than its competitors, glycerol was one of the first antifreezes to be employed in automobile engines. Glycerol is also known as glycerine. It is sometimes referred to as “nature’s antifreeze,” because it may be produced from both animal and vegetable waste. Ethylene glycol is the most often used automobile antifreeze, preferable to glycerol because of its lower freezing point, despite the fact that it is harmful to people. By virtue of its heat transfer qualities, ethylene glycol is also the most effective antifreeze in terms of providing protection against both cold and hot temperatures. The less harmful alternative to ethylene glycol is propylene glycol, which, however, must be used in greater volumes to accomplish the same results as ethylene glycol. In applications where ethylene glycol would be hazardous, such as the food sector, this product is ideal.

These formulations can be sold either as a concentrated solution or as a diluted solution diluted with water. In the United Kingdom, a 50 percent:50 percent dilution is commonly employed, which results in a freezing point of roughly -37°C (-34.6°F). However, in warmer or colder climes, weaker or stronger dilutions are used as needed. Other additives, such as phosphates and silicates, may also be present in antifreeze, and they can aid in the prevention of corrosion and the growth of biological matter.

Why Does Antifreeze Come in Different Colours?

You may be aware that antifreeze is available in a number of colors, ranging from red and blue to green and orange, which are achieved by adding dye to the solution. Why? This is primarily due to historical reasons; the varying colors represented either the location of manufacture, the brand that produced it, or the sort of corrosion-preventing chemical that was incorporated in the product. As an example, previous antifreezes were made with inorganic additive technology and were either blue or green in coloration.

Orange was the color of choice for these long-lasting antifreezes.

These days, the color of the product does not represent the actual content of the product, making it difficult to determine which chemicals are there simply by looking at the color of the antifreeze, which can be blue, green, yellow, or orange.

Is Antifreeze the Same as Coolant?

If you know antifreeze, you probably know that it comes in a number of colors ranging from red and blue to green and orange, which are formed by adding dye. Why? In large part because of historical reasons: the varied colors represented distinct regions or brands that produced the product, as well as different types of corrosion-preventive chemicals. For example, previous antifreezes had inorganic additives and were either blue or green in color. In the course of technological development, antifreezes became silicate-free and relied on organic acid technology.

As a result, simply looking at the color of an antifreeze bottle does not provide a clear indication of the compounds it contains.

The History of Antifreeze

In the late 1850s, a French chemist named Charles Adolphe Wurtz discovered the chemical compound ethylene glycol, but he was unable to find any use for it. Ethylene glycol was discovered to be an effective coolant some fifty years later, and it was also employed as a replacement for glycerol in explosives during the First World War, which was a major breakthrough. Following World War II, it was mass-produced for use in engine coolants, and it was crucial in the rise of both the automobile and aviation industries.

And Finally…Producing Antifreeze to Stay Warm

As if that weren’t enough, in 2014, scientists claimed that they had identified five families of Antarctic-dwelling fish that naturally manufacture “antifreeze” proteins, allowing them to live in the icy Southern Ocean. Because of this skill, they have become so successful that they account for more than 90 percent of the total fish biomass in the area. However, while we can’t guarantee that you’ll be able to remain warm in the Antarctic, we can offer you with a wide selection of ready-to-use and custom antifreeze, including environmentally friendly solutions.
