If you own a vehicle, you must have an idea about coolant, also known as antifreeze. The antifreeze usually comes in different colors, commonly green, orange, red, pink, blue, and yellow, but it is available in different shades too.

Each coolant color carries different properties, so it is essential to learn about them a little bit. 

Usually, it is not suggested to mix two coolants to protect the engine, but at times, you can mix pink and orange antifreeze together, which is effective for the engine’s life and safe to use. 

Experts recommend that one shouldn’t mix and match antifreeze of two different colors because it can lead to a lot of damage to the engine. The primary purpose of antifreeze is to protect the coolant system, which defeats the entire purpose of using a coolant in the first place. 

So, no, it is not recommended to mix antifreeze of two colors to get the best results for your engine. You should pick pink and orange antifreeze to make a blend if you must. Since they are both made from ethylene alcohol and thus, they are safe to mix to help the engine run for a long time. 

Read on if you are further interested in learning about the pink and orange antifreeze mixture!

What is Coolant?

Coolant, a mixture of distilled water and ethylene glycol, also called antifreeze, is an essential part of a vehicle. It is the primary tool of the system and is used for transferring heat to the engine. 

The reason why the engine needs heat from time to time is to avoid freezing or boiling. If the engine’s metal parts continue to freeze/boil over some time, it can damage the entire system.

Coolant also keeps the engine oil from becoming solid or gas since heat can only be transferred with a liquid in the system. Thus, it plays an influential role in the functioning of a vehicle. 

Many drivers understand that a vehicle needs a coolant for its smooth working and longevity. However, many people have no idea how to mix two coolants that work best for the vehicles.

Is it Okay To Mix Different Colors of Antifreeze?

Do you know that there are different colors of antifreeze available in the market?

The different colors available in the market include green, orange, pink, and blue antifreeze. However, you cannot mix all or any of the colors. 

So, once again, we would like to remind you that it is never a good idea to mix a batch, but if you have to, consult a good manufacturer and get good guidance on mixing the colors.

Many drivers love to play with the colors of antifreeze to bring out the best in their vehicles. So, even though it isn’t always a good idea, it is okay to mix different colors of antifreeze. It is essential to know the mixing process if you aren’t an expert in mixing these chemicals since it can cost you expensive bucks! 

What Happens If You Mix Two Colored Antifreeze?

The different colors of antifreeze available in the market come with a varied set of properties. However, you should avoid mixing two-colored coolants since they can impair the vehicle’s performance. 

Wrong engine antifreeze can lead to corrosion in the radiator and gradually cause damage to the water pump, radiator, cylinder gasket, and other tools in the vehicle. 

If you use a couple of coolants that are wrong for each other, they will certainly not react well. They form a jelly-like substance that thickens the flow of the coolant and leads to overheating of the engine. This leads to gradual damage to the engine and can cost a lot of bucks in the long run.

Is it Ok To Mix Orange and Pink Antifreeze?

Learning which color coolant will be the best for your vehicle cannot be evident. So, let us give you a safe side – mixing pink and orange antifreeze will always be a good idea for the engine. 

Yes, you can. 

Although it isn’t suggested to mix different colors before using them in engines, blending pink and orange antifreeze might be a good idea. 

You can mix these two colors without the fear of damage in the long run because they contain ethylene glycol, which can cool down the car engine. 

Pink coolant is a mix of inorganic as well as organic technology, which means that you can mix it with all sorts of coolants. Pink is used explicitly for Japanese vehicles like Toyota and Lexus. 

Orange is one of the most commonly used antifreeze found in the market and is often known as Dexcool. Like pink coolant, it also contains ethylene glycol-based chemicals; it has extreme anti-corrosion properties that prevent the engine from being damaged for a long time. 

When you mix orange and pink, the silicates in pink antifreeze will enhance the life of the coolant by many years (as many as five or even more). 

However, it is essential to know the exact measurements of the two mixing coolants to get the best out of your vehicle. So, you should let a professional do the blending and mixing of chemicals to get the best outcome!

So, How Do You Mix Pink and Orange Antifreeze?

When you mix these two coolants, it leads to a peachy color. However, you should ensure that the two coolants are measured well before pouring and need to be pre-diluted. 

To prevent your engine from freezing, we suggest you use a measurement of 50/50 of both coolants. You should also add about 20 percent of tap water for temperatures below 34 degrees Fahrenheit. 

Some of the top benefits of using pink and orange antifreeze are – 

• It helps in reducing corrosion and rust in the coolant system 
• It prevents the coolant system from freezing or boiling 
• Contributes to the extending the life of rubber and other components in the system
• Raises the temperature of the coolant system 

Also, summer is the best time to add pink and orange antifreeze as a mixture to your vehicle. However, the bottom line is that you should know which mixture would suit your vehicle and get guidance from a professional or an expert before mixing any two colors of antifreeze. 

Frequently Asked Questions 

#1. Can pink coolant be mixed?

It is recommended not to mix the pink coolant with any other antifreeze apart from the orange. Mixing pink with any other antifreeze will thicken the mixture and clog the coolant flow to the engine. 

Thus, it forms a jelly-like substance that doesn’t stay pure liquid and gets into a solid or semi-solid state, ending the whole purpose of adding a coolant to your vehicle. It leads to corrosion and, thus, gradual damage to the engine.  

#2. Does orange antifreeze turn pink?

There are coolants or antifreeze available in the market for a reason. They aren’t there to make the fluids look pretty but for the drivers to know which kind of coolant they are. 

Antifreeze not only differs in colors, like green, orange, or pink, but when mixed, they can turn into different colors. For instance, orange antifreeze can turn pink when distilled water is added. 

The reason why orange turns to pink when distilled water is added is due to the presence of Dexcool. So, yes, orange antifreeze does turn into pink. 

#3. What is pink antifreeze used for?

Pink antifreeze is usually used for alloy engines and meets the G-12 coolant specification, primarily found in Japanese vehicles.

However, European pink antifreeze is used on cars like Volkswagen, Porsche, and Audi. Thus, it provides excellent protection against corrosion, rust, and pitting to all system metals. 

#4. What kind of antifreeze is pink?

Pink antifreeze is used to reduce corrosion and extend the vehicle’s life for a long time. It is usually used in Japanese automakers and vehicles, including Toyota, Lexus, and Scion. 

The pink coolant is an organic acid technology (AOT) known for its more comprehensive services. It is less conventional than other colored coolants and promises better anti-corrosion services.

#5. Are all pink coolants the same?

Coolants are colored differently for a reason – each tall about their properties, so you can use the one that serves your purpose accordingly. 

However, all pink coolants are not the same. So, it is essential to read the information on the label of the bottle you plan to buy. Please do not mix the two coolants because they are of the same colors, and choose as per the model and engine of your vehicle. 

A Few Final Words

The main point is that all coolants come with properties that suit different vehicles. So, you must check the label of the coolant you are about to buy, or else it will cause damage to your vehicle instead of preventing the same. 

Even though pink and orange antifreeze can be mixed and extend the life of most engines, you must still seek guidance from a professional or an expert. So, go ahead and educate yourself on the matter before you call for a decision.

White foaming in the coolant or the antifreeze can mean that your gasket is about to start when the engine hits its combustion cycle. 

The foaming of the coolant could also mean that the antifreeze is heating up. This article will learn about the possible reasons for the antifreeze to get foamy and how you should tackle it. 

What Does A Foamy Antifreeze Mean? 

A foamy antifreeze could mean that the coolant has oil in it. You can remove the oil cap on the coolant to check the coolant level. If you see white foam on the coolant, it indicates a problem. In most cases, foam in the coolant is just the residue or crap getting stirred up in the flush or the filter tank. If you think that your head gasket is blown, you can check that by following a few simple steps. These steps are:-

• Suppose you see the coolant leaking externally or from below the exhaust. This is a sign of the head gasket being blown away. 
• If there is visible white smoke from the exhaust pipe, it indicates a faulty gasket. 
• Bubbles in the radiator tank of your car are also not suitable for high performance. 
• If your vehicle is experiencing overheating of the engine, then you should not take it lightly. You should either replace the coolant or get the problem fixed by a mechanic. 
• The formation of a milky white oil-like substance on the coolant is also an indicator of something wrong with the coolant. 
• Some faulty or fouled spark plugs in the car can also indicate a defective gasket in your vehicle. 
• If you are experiencing low cooling system integrity, you should consider replacing the coolant. 

How Can You Stop Your Coolant From Foaming? 

• Coolant foaming can be a very annoying issue. Without a properly functioning coolant, the car’s engine would heat up, resulting in an engine failure. 
• You add a small amount of calcium carbonate or calcium acetate to your coolant solution. When the foam disappears, then you can stop. You can repeat this process until you notice the foam disappearing. 
• Using distilled water as a base for the coolant can also stop the coolant from foaming in the tank. 

What Are The Causes For Foam Build-Up In The Antifreeze? 

• The primary or root cause of the antifreeze’s foaming is the presence of air bubbles in the coolant. These tiny air bubbles can get into the coolant because of a leakage somewhere in the coolant system. 
• Some other causes for foaming of the antifreeze can also be because of the lack of lubricating oil in the system. If there is an inadequate lubricating oil level in the system, the coolant can become agitated and start to get foamy. 
• Some sort of contamination in the coolant can also be responsible for forming foam in the coolant. Foaming can often be a sign of an underlying condition most of the time. 

How Do You Determine The Issue With The Foaming Problem? 

You can use a simple and easy test to determine whether the foaming issue is caused by a mechanical or because of the coolant. 

• Firstly you’ll need to collect a sample of the clean bottle with a lid. 
• You can then fill the bottle halfway with the cooling liquid. Then you need to close the cover of the cooling tank. 
• Then wait for all the bubbles inside the tank to collapse. There should be no visible foam on top of the fluid. 
• After that, keep the bottle on a flat and solid surface.

What Does a Milky and Brown Antifreeze Mean? 

A milky-appearing coolant always has some contamination in it. If your vehicle has a milky antifreeze, a foreign liquid is also mixed with the coolant. You will have to identify where this liquid is coming from and repair the leak. 

The time taken by the coolant to turn milky is more, so it means that the coolant is already contaminated by now, and you will have to replace it. It would help if you got a new cooling liquid when your old coolant turns milky. 

If your coolant is brown, it could mean the head gasket in your vehicle has blown. The oil from the blown gasket will mix with the coolant, and it will create a brown liquid resembling a chocolate milkshake. 

Does milky coolant always mean head gasket?

A milky coolant doesn’t always mean that you have a blown head gasket. Milkiness can be a sign of various other problems, such as it could mean that there is some oil leaking in the oil pan. If your vehicle has a milky coolant, then the chances that you have a head gasket issue are scarce.

If you are mixing some additional components into the coolant, it could disturb the original viscosity and concentration of the actual solution. Due to this reason, sometimes your coolant appears to be slimy, milky, or muddy. 

Frequently Asked Questions.

#1. How do you fix foamy coolant?

The best solution for fixing a foamy coolant is to replace the coolant. Suppose you are looking for a temporary solution to the foam problem on the coolant tank. You should be sure where the leak is coming from and rectify the situation. Then you can also add defoamers to the coolant tank—some of the defoamers available on the market help the tank emulsify the oil leak. Oil leaks are food for all types of bacteria. Therefore using a defoamer is not a long-term solution to this problem. 

#2. Why is my coolant or antifreeze boiling?

The coolant or antifreeze in your can reach boiling temperatures if there is some leak in the car’s cooling system. 

You might experience the pressure on the liquid to drop suddenly. Due to this pressure drop, the temperature of the coolant rises. Ultimately as you drive your car around, the coolant temperature will reach boiling point. 

If you can stop the leak and maintain the ideal amount of pressure in the tank and the engine, the coolant temperature will start dropping, soon reaching its average temperature.

#3. Is it normal for coolant to bubble?

Yes, it is very typical for coolant to bubble because of the air pockets formed inside it. You’ll find these air pockets created when the radiator is partially filled or incomplete. These air pockets in a coolant are responsible for improper flushing procedures. 

Air pockets inside a coolant will result in creating a lower coolant volume. This will create the operating temperature of the coolant to rise higher than average. You can check whether your coolant tank has air bubbles by seeing the coolant through the inlet valve. 

A Few Final Words

A foamy antifreeze is not ideal for the peak performance of your vehicle. If your car is functioning on foamy antifreeze, then it will cause damage to the internal sections of the car. 

We also talked about the significant reasons why the coolant would turn foamy. And mentioned some remedies for the same in the above article. You should solve the antifreeze foaming issue as soon as possible for your car. 

If there are some severe issues, consider taking your car to a professional. They can easily diagnose the problem and solve it. Thank you for reading the article. If you have more doubts and questions about the color and form of your antifreeze, do drop us a word and we will get back to you quickly.

Paying attention to your engine’s pipes and systems is important. It becomes even more imperative during and immediately after the winter months since the liquids inside the engine can freeze.

Many methods are put into place to deal with this situation. Antifreeze or engine coolant was commonly added to water and engine lube in automobile cooling systems, preventing damage to radiators. 

However, the same has now been replaced by long-life engine coolants. This is because of their property of lowering the freezing point of water. However, is this property enough to melt ice? If I add antifreeze to frozen water, will it melt?

This article answers questions surrounding the thawing, freezing, melting of ice, and whether antifreeze can melt ice. 

What Kind of Water Pipes Freeze and When?

Texashelp says water pipes’ potential of freezing and bursting increases when the outside temperature drops to 20 degrees Fahrenheit or below. Here is the list of pipes that are utterly likely to freeze:

• Outdoor hose bibs
• Water pipes in basements
• Swimming pool supply lines 
• Water pipes that run against the exterior walls

What Is the Best Method for Melting Snow and Ice?

According to achr news, you can classify systems that melt ice in three segments:. 

• Class 1: systems let snow accumulate during snowfall and then melt it many hours after it stops snowing. Their heat delivery is 80 to 125 Btu/sq.ft.
• Class 2: systems are used where keeping the path clear of snow, even if the pavement is wet, is important. One can use these systems in commercial areas, and they deliver 125 to 250 Btu/sq.ft. 
• Class 3: systems are meant for instances where you want no snow to accumulate and ensure that the surface remains dry. These are used for critical traction, such as sloped ramps, pavements, and helicopter pads.

Will Antifreeze Melt Ice in Pipes?

Does antifreeze melt the snow? No, antifreeze is meant to prevent freezing of the pipes and not thawing already frozen pipes. 

What Liquids Will Melt Ice?

Sodium chloride liquid brine is known to melt ice quickly. The mixture is a solution of one-quarter parts of sodium and 3-quarter parts water and. As the liquid brine dries, it leaves a dry salt coat that reacts and prevents ice from getting stuck on any surface.  

What Will Instantly Melt Ice?

A salt-based ice melt is considered the most convenient and best approach for melting ice, particularly in winter. wikiHow suggests alternative methods for melting ice. These include using rock salt atop the ice. 

Products that happen to be exothermic deicers, particularly those containing magnesium chloride and calcium chloride, are effective in all weather conditions. 

Ice Melt Safety

One can spot the exothermic term mentioned emphatically on most ice melts. Also, do not forget to wear safety gloves when dealing with this ice melt. One should avoid applying ice melt in thick layers since this makes the product ineffective. 

Instead, it is suggested to carry out ice melt application in thin layers before, during, and after the snowfall. Ensure even yet thin distribution on the surface. Put the second layer when some snow has accumulated and another atop when the snow has stopped. 

Users should also avoid the application of ice melt to porous surfaces such as roofs and brick since this can lead to salt buildup in the material, which can cause long-term structural damage. It is generally safe to use ice melt on concrete and wooden surfaces. If the use of ice melt to brick is unavoidable, quickly remove the salt once the ice melts. 

When To Use Liquid Ice Melt vs. Solid Melt?

Liquid ice melt is a proactive approach to ice and snow management. It is most effective when used as a pretreatment and is best used before the winter season hits. 

Solid ice melt is as effective as liquid melt when applied before, during, and after a snow event. Also, solid ice melt can be used at any time, unlike its liquid counterpart, which is best used when the winter season is approaching.

Can You Use Antifreeze on Your Driveway?

Does antifreeze stain driveways? Garden guides answer that antifreeze can leak from a container or the engine and stain the driveway. However, since antifreeze is water-soluble in nature, one can easily clean it with ordinary tap water and regular detergent. 

Stubborn stains can be dealt with automatic dishwasher detergent. Make a concentrate with powdered detergent and water or directly pour liquid detergent atop the stain. Scrub over the area with a brush and let it stay overnight. Rinse and repeat as required. 

How To Thaw a Frozen Pipe After a Storm?

Here’s how one can thaw a frozen pipe after the storm. 

• Inspect all faucets in your house. It is likely for more than one pipe to be frozen. 
• Keep the faucet open. Doing so will allow ice to melt as water begins to flow.
• The frozen portion of the pipe can be heated. One may use an electric hair dryer or even wrap the pipes with towels dipped in hot water. However, one must always ensure that no electrical cords come in contact with the pipe in any case. Also, avoid using open flame devices since they release carbon monoxide fumes into the air. 
• If all efforts of locating the frozen pipe seem to go in vain, call a licensed plumber to help locate the frozen area. 

Final Thoughts 

Antifreeze is meant for preventing the freezing of pipes and not thawing pipes that have already frozen. It will hence not melt ice. Ice is best melted by using a liquid ice melt or solid ice melt, depending on the need.

Antifreeze can circulate for about 20 to 30 minutes through the engine block system and radiator hoses. Antifreeze is an additive added to a coolant to lower the freezing temperature of the water-based liquid. 

Coolants effectively take away the heat from the engine to maintain an appropriate working temperature. To know what effects coolants and the time for circulation, you need to start from the basics. Let’s jump into the facts to learn a bit more about your car and its needs without meandering. 

What is Antifreeze?

First and foremost, you should know what exactly Antifreeze is.

Antifreeze is an additive that lowers the freezing point of a water-based liquid. It is a mixture of water and either ethylene glycol or propylene glycol. Antifreeze is an in-demand fluid that runs the automotive industry. Without a coolant, your engine is not efficient enough.

One needs to have their facts clear about things like coolant, radiator, thermostat as they could contribute to our daily used cars. Everyone, including you, put coolants like Antifreeze into the car’s radiator to help regulate engine temperature and prevent corrosion by maintaining proper fluid levels.

What is antifreeze made of?

Antifreeze, a coolant and lubricating agent, needs appropriate proportions of various components such as ethylene glycol, propylene glycol, methyl ether, glycerol, and others. 

Water has also been proved to be an adequate coolant due to its capability of conducting water effectively. The only valuable property of water as a coolant is that it can easily take away heat from your car’s engine, and Glycol-based coolants are thus preferred over water.

Most coolants are made up of three constituents: water, additives, and a base product. The base products that are most used are ethylene glycol and propylene glycol. 

Propylene glycol has negligible toxic properties and thus could be used in any system, including cars, food processing units or water distribution pipelines. 

Another alternative for propylene glycol is propylene glycol methyl ether which is extensively used in diesel cars due to its non-volatile nature. 

Uses of Antifreeze

Antifreeze is used mainly for two purposes. They are:

• Antifreeze lowers the freezing point of water-based coolants, thus increasing the efficiency of the coolant.
• It helps lubricate the parts of car engine pipes and radiator, thus preventing corrosion.

How Does Antifreeze Work?

Antifreeze is loaded in a reservoir beside the radiator of the engine. The reservoir leads to other engine systems and other components of the same. The Antifreeze reservoir is associated with a cooling system as a whole of the car.

A pump circulates Antifreeze and water. The circulating substances such as Antifreeze and water conducts heat, thus taking the heat away from the engine system. Along with Antifreeze, few other components work to maintain the engine’s temperature.

Thermostat

For example, the thermostat is an essential part of the system, and it is a valve fixed between the radiator and the engine block. Whenever the circulating fluid temperature rises too high, the valve opens, letting the fluid flow into the radiator, where it gets to the average temperature. 

The thermostat valve would remain closed until the circulating fluid reaches a specific high temperature, letting the fluid circulate to take away the heat from the engine block system. 

Radiator

Now, a question may arise: How does the radiator help the liquid cool down. Well, it is a fan that is present in the engine block that forces the air to flow across the fluid present in the radiator. 

Both the thermostat and the fan are essential for efficient cooling of the engine and proper functioning of the coolants that are Antifreeze and water. 

Coolant

When the car is moving, that is when the engine is at work, it would eventually get hot in the absence of circulating coolant. So, to avoid heating the engine, the coolant is continuously circulated through the engine block. 

The fluid circulates through a chain of pipes fixed to the radiator, and it moves to the radiator once the liquid gets heated up, passing by the thermostat. 

After it is cooled in the radiator, the fluid flows out of the radiator and goes into the water pumping system, from where it is pumped into the block, where it absorbs excess heat generated by the engine. The cycle is continued till the car is in working mode. 

Why and When Do You Need To Change AntiFreeze?

A car’s engine needs several fluids such as engine oil, power steering fluid, a coolant such as Antifreeze etc. All of these fluids need to be regularly checked and changed. For coolant, you must check the Antifreeze level and add it whenever required. 

The specific instructions on when to change Antifreeze and how much Antifreeze should be added are present in your car’s manual. It would be best to give that manual a read before changing your Antifreeze. The process of changing Antifreeze is also explained in the manual. 

High mileage cars need special Antifreeze to sustain the large number of miles a car runs for a particular time. 

Roughly, you need to change the Antifreeze after 50,000 miles of driving. Some new models that provide better mileage need a change of Antifreeze every 10,000 miles of driving. 

Overused coolant or a wrong coolant might cause the radiator to fail by generating corrosion. Overused coolant will lose the capacity to conduct heat away from the engine, thus negatively affecting the engine. 

How Long Does It Take For Coolant To Go Through The System? 

It depends on the car model, and it might take 20-30 minutes which may vary with atmospheric temperature and condition of the car. 

How Long Does It Take Antifreeze To Circulate? 

Antifreeze works in the same way as coolant, the only difference being that coolant has more water mixed in it. Therefore, it would take about the same time as coolant, ie, 20-30 minutes.

Frequently Asked Questions

#1. How do I know if my coolant is circulating?

You would know by checking the temperature of the radiator fluid, and you can quickly insert a finger to check or use a thermometer.

#2. Does coolant circulate all the time? 

Yes, It circulates whenever the car is on the go, and the circulation stops as soon as the engine stops. 

#3. How long does it take for coolant to get from reservoir to radiator? 

It might take 3 to 5 minutes, depending on the model and condition of the car. 

A Few Final Words

The time duration of circulating Antifreeze depends on a few factors, such as the car model and its condition. Environmental temperature also influences time, and it takes longer to circulate in winter than in hot summer afternoons. 

We hope this article was able to shed light on the working of antifreeze in the car, what all you need to take care of and how long it takes for antifreeze to work properly. You can ask us more questions if we have missed out on any details.

You might also like to read: What Does Antifreeze Smell Like? And Can You Mix Dex-cool And Universal Antifreeze?

It is natural for automobile engines to get overheated, and it is also essential that they remain cool for the engine to last longer. The car coolant is the best and only solution to this. Car coolants are colloquially also called Antifreeze. 

The coolant ensures perfect lubrication for all the moving parts of a vehicle, thus preventing any wear or damage to the gasket (mainly the head) water pump. It helps the piston maintain its timing and the cylinder remain intact.

Dex-Cool is an antifreeze manufactured by General Motors (GM). Universal Antifreeze is another variety of the same product. However, universal antifreeze and Dex-cool are not one and the same thing, and it is not a good idea to mix them. Read on as we discuss more on Antifreeze and Dex-cool specifically.

What is Dex-Cool? 

Dex-Cool is a coolant or Antifreeze from GM manufactured and sold since 1995. It is the brand name only and not a product that differs from other coolants. It is similar to Prestone, which is also an antifreeze/coolant. 

There is also no denying it is a unique type of Antifreeze and only a select brand of coolants have them. GM sold it to all their customers with the instruction that it is the best Antifreeze for their automobiles. 

GM claimed that it would keep the functions and vital parts of the vehicles in top condition and prevent any damage that other coolants might not be able to avoid.

Also read: Foamy Antifreeze – To Use Or Not To Use?

The Ingredients & Composition of Dex-Cool

Many materials make DEX-COOL unique from many other coolants. Methanol and ethylene glycol form part of water-based Antifreeze. These ingredients are combined and inserted into the engine to protect your car engine from overheating. 

It is achieved by increasing the resistance of the vehicle parts to higher temperatures. Other Glycol-based coolants are odorless and colorless. But these ingredients do not form part of Dex-Cool, although they are commonly found in other antifreeze. 

Various phosphates combine along with silicates to produce Dex-Cool.

Problems Flagged by Dex-Cool Users

Even though Dex-Cool is a very popular antifreeze available in the market today, there are some issues that the users face with this coolant. Some of the problems faced by Dex-cool users are:

• Corroded radiators
• Clogged radiator caps 
• Eroded water pumps

GM claimed that the antifreeze will ensure the protection and longevity of vehicle parts and is long-lasting compared to other coolants. They also said that it is sufficient to change once in five years or after running a minimum of 150,000 miles, whichever occurs earlier. However, as the problems above suggest, all was not great with Dex-Cool.

Can Dex-Cool Be Used With Any Other Coolant?

If you are wondering if Dex-cool can be used along with any other coolant. You would be disappointed to know it is not advisable. The reasons are as below:

• Using it with other coolants is sure to degrade the integrity of the coolant 
• It would cause damage and repairs to the entire coolant system in the automobile
• It would shoot down the five-year and 150,000-mile guarantee (by GM) to two years and 30,000 miles, respectively.

What Happens If You Mix Dex-Cool And Regular Antifreeze?

It should be noted that other antifreeze coolants and Dex-Cool are incompatible. Even though they can operate together for a short period, long-term usage can lead to forming a substance that resembles a Gel. 

The Gel-like substance becomes extremely destructive to numerous cooling system components. As a result, using only Dex-Cool for a Chevrolet or GM car is the best option. 

However, other options do exist. 

Several coolant manufacturers now sell alternatives that are not Dex-Cool and yet can be mixed with it without risk of contamination. One should carefully examine the instructions in the instruction booklet and the tag label on the coolant you intend to use.

So How Do We Use Dex-Cool effectively?

• There are many authorized and authentic dealers selling Dex-Cool, including Shell, Prestone, etc. If one buys another coolant, they must double-check whether the specifications align with the GM6277M. 
• In case you wish to replace the existing coolant with Dex-Cool, it is advisable to completely drain out the old one by wheeling your vehicle to a good garage. If remnants of the old non-Dex-Cool are still present, and you accidentally mix it with Dex-Cool, the consequences would be dangerous, as mentioned earlier.
• Dex-Cool, as discussed, has a different structure compared with other coolants. Its design helps maintain aluminum-constructed engines. Dex-Cool can minimize corrosion in aluminum-type engines. 
• Other coolants, green coolants, change their color when the vehicle parts start corroding. It is this indication that helps essentially as far as corrosion is concerned. But this kind of identification fails with an aluminum engine. The green coolant never changes color, and this is where Dex-Cool was failing GM customers.

GM had to pay heavy compensation due to the class action suit, and they accepted the responsibility of replacing or repairing the automobile for their customers. They are still selling the Dex-Cool with warnings about proper usage and disclaimers. 

Frequently Asked Questions

#1. What happens if you use green coolant instead of Dex-Cool?

To distinguish Dex-Cool coolant from other types of coolants, the makers often use a different hue for it. Dex-Cool is typically orange or red instead of the conventional coolant’s green. 

The green color of ordinary coolant interacts with the formation of rust or corrosion, thus alerting you to replace the existing coolant in your automobile. Dex-Cool’s bright orange color makes it difficult to identify the replacement time, thus complicating the process.

#2. Does GM still use Dex-Cool?

The problems of the past are done away with. The earlier issue of the Gasket getting spoiled due to its interaction with the Dex-Cool has been solved. Many of the vehicles manufactured by GM do require the Dex-Cool.

A Few Final Words

One needs to look into the core issue too. The coolant might be running low as there might be a leak that has gone unnoticed. Such ignorance would pave the way to major repairs and a breakdown ultimately. 

Also, if you are planning to use dex-cool, we suggest that you see the usage instructions provided by GM to ensure that you do not damage your vehicle parts further. 

Thank you for reading, we hope this was an interesting read, especially since there was a class action lawsuit that happened because of the problems with Dex-Cool and other antifreeze. Thankfully, all that is in the past now.

As a result of an increased boiling point, the coolant temperature will be higher. This coolant makes its way through the engine to ensure that a regulated temperature is maintained. To put it simply, antifreeze is intended to prevent the coolant from freezing during extreme temperatures.

The antifreeze solution is mixed with water before being added to the coolant reservoir. It’s likely that on occasions where you have been refilling the coolant reservoir with the product you have caught a glimpse of the scent.

Many would suggest that antifreeze smells rather sweet. Antifreeze that is yet to be diluted with water is going to smell quite a bit sweeter than diluted antifreeze. 

It is important to recognize that the smell of antifreeze can change in particular situations.

While some may find it tempting to smell the antifreeze more regularly than recommended due to the unexpectedly sweet scent, it is important to familiarize yourself with the other type of smells that can be possible indicators of issues with your car. 

Antifreeze has a particularly high boiling point and can emit fumes that smell sweeter than normal antifreeze. You are likely to notice a presence of hot antifreeze entering through the air in the car making the smell a little easier to identify, 

Antifreeze has a particularly high boiling point and can emit fumes that are sweeter in scent than normal antifreeze.

You are likely to notice a presence of hot antifreeze entering through the air in the car making the smell a little easier to identify, however, you are unlikely to be in direct contact with the fumes of the antifreeze to be able to distinguish the exact scent.

If you are a little unsure, you should expect hot antifreeze to smell slightly sweeter.  

Antifreeze is also going to smell different following interaction with engine oil inside your car, something which shouldn’t happen intentionally.

The smell of the antifreeze is going to be milder when it has mixed with oil and could be an indicator that there are problems with the car that need to be looked into immediately. 

If this should happen to your car, it could cause a significant amount of damage and the smell may not be as pungent or strong as you would expect.

If anything it is going to remain sweet but as mentioned not as strong as normal antifreeze and this can make the issues difficult to detect until severe damage has been done.

Are the fumes of antifreeze harmful?

Antifreeze should not be harmful if it is used as intended. As with any product, there is the risk of potential skin irritations if contact should occur and if consumed in excessive amounts, antifreeze can lead to a spectrum of severe health illnesses including heart problems and brain damage. 

One of the main ingredients inside antifreeze is ethylene glycol and this can cause the eyes and respiratory tract to become irritated.

Although inhaling small amounts isn’t going to have such detrimental effects, despite the sweet smell seeming appealing you should avoid inhaling the fumes of this product due to the issues that can occur as a result of this. 

How do you remove the smell of antifreeze from your engine?

There are some steps that you can take to remove the smell of antifreeze from your engine.

The use of Lysol spray is likely to be effective if used repeatedly until the smell has disappeared. This should be sprayed on the fresh air intake vent. 

Why can I smell antifreeze inside my car?

If the smell of antifreeze is prominent in your car it could be a sign that the heater core is leaking and needs to be replaced. The purpose of the heater core is to heat the cabin inside your vehicle.

This is typically an unnoticeable problem that only becomes prevalent when an issue has occurred. If your heater core has become damaged or has a leak, a particularly strong smell of antifreeze is going to be present through the vents of your car.

Once this odor is present in your car it is practically unnoticeable, hence why it can signify a severe issue that should be looked into to avoid further damage occurring while ensuring that the car is safe for you. 

Why can I smell antifreeze outside of my car?

If the smell of antifreeze is prominent in the outdoor environment surrounding your car, it could be an indicator of many problems.

There is one of two places that this smell could be coming from and that is the radiator or heater hose. It may also be an issue with the cylinder head or possibly a failed gasket. 

Final Thoughts

Antifreeze serves an important purpose inside a car. Antifreeze plays a crucial role in your car’s performance. Not only is it intended to keep the engine cool at a regulated temperature, but it also helps to ensure that your engine doesn’t become overheated.

Although the lack of antifreeze in your car isn’t going to cause it to become damaged immediately, over time it is likely to become problematic. 

Some may find the sweet smell of the antifreeze solution to be fairly similar to the smell of syrup or other sweet products and although this can make it tempting to smell, doing so in excessive amounts can lead to severe health complications and so ideally, doing so should be avoided.

The smell of antifreeze can also come in useful for identifying several issues with your car. The severity of the smell is going to differ depending on the issue. As mentioned following interaction with heat the smell doesn’t differ dramatically and remains sweet but not hugely present in the atmosphere.

However, when the solution has mixed with engine oil the smell becomes easier to identify as it is milder than what it would typically be.

It is also possible that the smell of antifreeze could be a sign of a leak inside your car and this is particularly the case if you smell the product inside the cabin and surrounding the outside of the car too.
