Which antifreeze do I use? (Correct answer)

Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don’t need to be changed as often. Cars made before 1998 usually need antifreeze that isn’t OAT-based and that does contain silicate.

What type of antifreeze do you use?

  • The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection. Another common antifreeze formula is Dex-Cool®, a coolant formula approved for use in GM vehicles.

How do I know which antifreeze to use?

You should check your owner’s manual, to check on what type or color of antifreeze your car takes. One of the most common, and longstanding coolants of this type is DEX COOL®, which was developed by GM in the late 1980’s and has been used ever since.

What happens if you use the wrong color antifreeze?

If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail.

What happens if you mix 2 different antifreeze?

If you mix two different coolants together, it will create a think substance that resembles that of a jelly. If this happens, the coolant will not be able to do its intended job. Instead, it will cause the engine to overheat. The damage can reach gasket, water pump, and radiator.

What color is the universal antifreeze?

Traditional North American “ green ” antifreeze, the original “universal” formula that everybody used until the introduction of today’s extended-life coolants.

Does it matter what color antifreeze you put in your car?

But what about different colored coolants? The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple.

What happens if you use green coolant instead of orange?

The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.

Is green coolant bad for aluminum?

While the manufacturers of these coolants recommend only using them in an aluminum radiator, as opposed to the copper/brass radiators, we still don’t recommend them in our all-aluminum radiators. We recommend the traditional yellow/green coolant because it has always worked for us.

What’s the difference in antifreeze color?

Typically, Valvoline says, coolant comes in green. Each manufacturer designs its engines around a specific coolant or antifreeze standard with different additives. GM, for example, uses orange-colored Dex-Cool antifreeze, while VW’s preferred coolants are typically yellow- or blue-colored, Hemmings reports.

What is pink antifreeze used for?

Our specially designed formula for Audi ® 1997-2007, Volkswagen ® 1997-2008, Porsche ® 1999-2009, and Jaguar ® 1999 and newer. This technology regulates your engine’s temperature, prevents freezing and protects the engine from corrosion.

Can I use blue coolant instead of green?

You can, but if it was me, I’d rather fill the system with distilled water until I got the proper coolant for the car. Whatever you do, don’t mix green/blue with orange. It will gel up and cause major problems. You should not mix anti-freeze or coolants.

What is green antifreeze used for?

Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle’s cooling system. That older formula is typically meant for vehicles made before the year 2000, which were built with more steel and copper components than modern vehicles.

What is the red antifreeze?

Red antifreeze is commercially known as Dexcool® that lasts longer than other types of antifreeze. This hybrid technology leads to the production of red antifreeze. When compared with green antifreeze and other older versions of antifreeze compounds, red antifreeze is more stable and it improves the water pump life.

Is universal coolant safe?

Which type of coolant should you use to top off or refill your cooling system? Even so, universal coolants are formulated to mix with virtually any coolant. The makers of these product say their antifreeze can be safely used in any year, make or model of vehicle.

You must be extremely careful not to damage the threads on the aluminum head, or else you will most likely have the dreaded spark plug coming out of the head issue. Despite the fact that I was unable to locate the original articles, I had created a technique based on two or three posts that had supplied valuable information. I’d want to thank M Feeney for his contribution to the world of literature. How to change the spark plugs in a 4.6L5.4L engine Because I they’re hard to reach, (ii) if you do it incorrectly, you’ll strip the delicate aluminum heads, and (iii) you’ll need a blow gun to clear out the spark plug holes in the heads to ensure that no dirt gets into your engine, changing these plugs is extremely tough.

Please read the following to have a better understanding of the severity of the head problem: You should visit your local dealership if you are not up for this.

You could expect to pay roughly $55 for the plugs.

If you are confident that the dealer / technician has completed this task several times, I recommend paying a little bit extra up front.

***WARNING*** Otherwise, when you remove the plugs, all of the trash from the engine’s combustion chamber would fall into your engine’s combustion chamber, causing it to stall (very bad).

In order to prevent the plug from falling out, spray only a small amount of Penetrating Oil within the hole.

In order to avoid harming the aluminum head, follow these instructions: Expel any remaining penetrating oil or muck from the hole by blowing it out a second time.

In case you are unsure, you can consult your mechanic.

It is very important to remember the following: To tighten the plugs, you MUST use a torque wrench.

***WARNING*** Keep them as loose as possible!

A screw that is too tight may cause the threads to be stripped and/or your plugs to shoot out while you’re on the road.

Clean the rubber boot on each COP and add a small amount of dielectric oil to the end of each plug boot to aid in the sealing of the boot and the plug together.

In the event that you are unable to get them most of the way in with the hose, have a look and determine why this is not possible.

Using a short ratchet, the plugs should be tightened to a torque of 13 pounds-foot, which is just hand tight.

Even as it is, the threads in the aluminum heads are prone to damage.

To help seal the plug boots, dab some dielectric oil onto them as well.

You should be able to change the plugs in around 45 minutes if you’ve done enough of them; nevertheless, don’t be shocked if it takes a few hours the first time around. Moderator: Dave (FTE) Forum Rules and Regulations Don’t forget to switch off the sound if your mind begins to wander.

What Is Engine Coolant?

Engine coolant, often known as antifreeze, is a mixture of water and antifreeze that prevents the radiator from freezing in extreme cold and overheating in extreme hot conditions. There are many various types of coolant available, so it’s crucial to understand which one is best for your vehicle.

Different Coolant Types

Different types of coolants are required for different types of cars. Every sort of vehicle, from diesel engines to American, Asian, and European automobiles, may be found in a variety of configurations. In order to maintain its specified engine type functioning in severe temperatures, each one is uniquely designed for that purpose. The distinctions between the two types of antifreeze are critical in ensuring that you receive the suitable antifreeze for your car.

IAT Coolant

The IAT formula, also known as Inorganic Additive Technology, is the most widely used type of liquid antifreeze. IAT coolant ZEREXTM Original Greenhas been in use for decades and has a composition that has been shown to give outstanding corrosion prevention.

Dex-Cool™ Coolant

The antifreeze formula Dex-Cool® is another popular choice, and it is certified for use in General Motors cars. An alternative such as ZEREXTM Dex-Cool Antifreeze/Coolant, which has been certified by the OEM and meets or exceeds several industry criteria, is a good choice.

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:

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.

How to Choose the Right Coolant for Your Car

A significant portion of Hy-per Lube’s revenue is generated by our well-known Super Coolant product, and we know a thing or two about the performance of cooling systems. Begin with the fundamentals, which a large number of people overlook when it comes to cooling systems. Car maintenance is a vital component of owning and operating a vehicle. Maintaining your car might help you save money by allowing it to run for a longer period of time. Regular excursions to the shop to take care of maintenance, such as changing the oil, are relied upon by many automobile owners.

In order to change the engine coolant, you must first cleanse the engine with water.

The selection of the appropriate coolant is influenced by a number of factors, including the vehicle’s age and kind. Here’s how to select the most appropriate coolant for your wheels.

What Is Engine Coolant?

Engine coolant prevents your engine from overheating, therefore saving you money on expensive engine repairs. When your engine is exposed to severe temperatures, both hot and cold, coolant helps to keep it running smoothly. When your automobile is in operation, the engine runs hot, hot enough to cause damage to critical components. When the engine of the automobile generates heat, the coolant absorbs it and circulates it back to the radiator. Excessive cold throughout the winter months can cause your engine block to freeze and even shatter in some cases.

  1. Engine coolant, sometimes known as antifreeze, does not freeze at sub-zero conditions, contrary to its name.
  2. Even though engine coolant is available in a number of various formulations, its essential constituents are ethylene or propylene glycol and water.
  3. Coolant is pumped into and circulated through the engine block from this reservoir, protecting your car from severe heat or cold.
  4. When the automobile is operating, an engine coolant pump will provide coolant to the engine block.
  5. When you initially start your automobile and let the engine to warm up, the coolant will bypass the radiator and go directly into the engine.

Why Do I Need Engine Coolant?

In order to avoid an expensive repair bill, it is necessary to keep your engine coolant level at a constant level. In both hot and cold weather, coolant helps to keep your engine from becoming overheated. While in use, the engine of your automobile generates excessive heat, which can cause damage to critical components. When the engine of the automobile generates heat, the coolant absorbs it and circulates it back into the radiator. Excessive cold can cause your engine block to freeze and even break during the winter months.

  1. Engine coolant, sometimes known as antifreeze, does not freeze at temperatures below zero degrees Fahrenheit, contrary to its name.
  2. Even though engine coolant is available in a variety of formulations, the most fundamental components are ethylene or propylene glycol and water.
  3. Coolant is pumped into and circulated through the engine block from this reservoir, protecting your car from severe heat or cold temperatures.
  4. When the automobile is operating, a pump will deliver engine coolant to the engine block.

As soon as you turn on your automobile and let the engine to warm up, the coolant will bypass the radiator and go directly into the engine. During normal operation, the coolant system valve will open, allowing coolant to flow through the radiator as the vehicle warms up.

What Makes a Good Coolant?

An excellent engine coolant prevents your car’s engine from being frozen or overheated at the same time. It can also help to preserve your engine from corrosive substances while also improving its overall performance and efficiency. Who knows what goes into making a high-performance engine coolant.

  • An excellent engine coolant prevents your car’s engine from becoming frozen or overheated simultaneously. Aside from that, it may help to preserve your engine from corrosive substances while also improving its overall performance What chemicals go into making a high-performance engine coolant are you asking yourself?
  • Ethylene glycol is a chemical compound. Ethylene glycol is the primary active element in the majority of engine coolants. Following World War I, it was discovered that it could be utilized as a coolant component. Specifically, this chemical is important for ensuring that the liquid running through your car’s engine does not freeze in extremely cold temperatures and that it does not evaporate in extremely hot temperatures.
  • Propylene glycol is a chemical compound. Propylene glycol is used in some engine coolants instead of ethylene glycol in others. Propylene glycol has a higher viscosity than ethylene glycol, which indicates that ethylene glycol has a higher heat transfer efficiency. Ingestion of propylene glycol is regarded less harmful than ingestion of ethylene glycol, which is a big selling factor for car owners who have children or pets in the car.
  • A class of anti-corrosion agents. Most engine coolants are composed mostly of water and ethylene glycol (or propylene glycol), but variable additions to prevent corrosion result in a variety of distinct types of engine coolants. The proportions of these various substances might fluctuate depending on the place of origin. For example, carboxylates and phosphates are used as anti-corrosion agents in the engine coolant of automobiles built in Asia. The use of silicates as an anti-corrosive additive in engine coolant for Asian-manufactured automobiles is prohibited. Engine coolant for European automobiles, on the other hand, is made up of a combination of silicates and carboxylates to protect the engine from corrosion.

One anti-corrosive is not always superior than another in terms of effectiveness. A variety of components are employed to address a variety of conditions. Automobiles manufactured in Asia, for example, have experienced problems with heat transmission. As a result, coolants containing silicates are not used in the engines of automobiles built in Asia. Phosphates and carboxylates, on the other hand, perform the anti-corrosive function. Engine coolant was introduced in Europe to address a different issue.

As a result, engine coolant for automobiles manufactured in Europe does not include phosphates.

The presence of antifreeze in engine coolant is not always guaranteed, though.

In plain water applications, some additions can be a viable alternative to conventional chemicals.

What Are the Different Types of Engine Coolant?

The engine coolants that are used in different sorts of automobiles are designed to work precisely with those vehicles. Color and name are used to categorize the different types of coolant. Always be sure to use the variety that is advised for your vehicle. The following are the six types of engine coolant:

1. Inorganic additive technology (IAT)

The color of IAT engine coolant is green. Ethylene glycol is used in its production, with silicate and phosphates added to keep it from corroding. It is commonly seen in older automobiles, such as those made in the United States before to the late 1990s and early 2000s. It is less efficient than certain modern forms of engine coolant since it is an older formulation. Depending on whether your vehicle requires IAT coolant, you will need to cleanse and replace it generally every two years or every 24,000 miles.

2. Organic acid technology (OAT)

A green color is seen in the IAT engine coolant. ethylene glycol is used in its production, with silicates and phosphates added to prevent corrosion. Vehicles constructed prior to the late 1990s in the United States are most commonly equipped with this technology. It is less efficient than certain modern forms of engine coolant since it is an older recipe.

Depending on whether your automobile requires IAT coolant, you will need to cleanse and replace it generally every two years or every 24,000 miles. A significant amount of silicate is contained in IAT formulae, which safeguard your car’s engine by reducing the effects of rust on it.

3. Hybrid organic acid technology (HOAT)

Organic acid hybrid technology is one of the three primary types of engine coolant, and it is further subdivided into a number of subcategories. Traditionally, yellow HOAT coolant was used. It is now available in a variety of vibrant hues. HOAT coolant is available in a variety of colors, including yellow, orange, green, pink, and blue. Consider the brand name rather than the color of the liquid when selecting a HOAT coolant to ensure that you are purchasing the correct product. Combining the OAT formulation with the IAT formulation, the HOAT formulation has a powerful anti-inflammatory effect.

It should be replaced at the same intervals as the OAT coolant: every five years or every 50,000 miles, whichever comes first.

4. Phosphate-free HOAT

HOAT that is devoid of phosphates is often turquoise in hue. This NAP-free mixture, which is based on ethylene glycol, combines organic and inorganic corrosion inhibitors to help keep your engine running at peak performance. It does not include any phosphates, such as nitrite, nitrate, or borate, which are harmful to the body. In addition, it is a low-silicate recipe. HOAT is compatible with a wide range of automobiles, including BWW, Volvo, Tesla, Mini, Audi, Jaguar, Mercedes, Porsche, Rolls-Royce, Saab, Volkswagen, and many other makes and models.

5. Phosphated HOAT

Phosphated HOAT is a corrosion-inhibiting agent that combines phosphates and organic acids to protect the engine’s internal components. The color of the coolant is often either pink or blue. Phosphated HOAT coolant is often suggested for use in automobiles built in Asia, such as those manufactured by KIA, Honda, Hyundai, Nissan, and Toyota, among other manufacturers. The use of this sort of coolant is required by Asian automobile manufacturers due to concerns about heat transfer. Carboxylates and phosphates, rather than silicates, are used in the coolant to prevent corrosive activity in the engine of your automobile.

6. Silicated HOAT

The rich purple hue of the Silicated HOAT is generally what distinguishes it. It works by inhibiting corrosive activity in your engine through the use of silicates and organic acids. This formulation is devoid of the following contaminants: nitrites, nitrates, phosphates, borates, amines, and imidazole. Instead, it makes use of organic silicate technology. For mild use, the coolant provides protection for five years or 150,000 miles, whichever comes first. The protection provided by this formula is three years or 300,000 miles in the case of heavy applications.

When performing engine coolant maintenance on your own, keep note of how many miles you have driven and how long you have been doing it.

It’s important to note that if your automobile has been updated with newer or different parts, the type of coolant it requires may alter. Always conduct thorough research to ensure that your vehicle is kept in the finest possible functioning condition.

What Is the Best Coolant for My Car?

The optimum engine coolant for your automobile is determined by the type of vehicle, its age, and the location where it was built. It will be easier to pick the appropriate coolant if you know the brand, model, and year of your car first. Choosing the incorrect product might result in poor performance or, in the worst case scenario, engine failure on the spot. Follow these suggestions to ensure that you make the best decision.

Check the Color

A correlation exists between different hues of coolant and varying levels of automobile compatibility. For example, IAT coolant is normally green in color, while HOAT coolant is typically turquoise in color. However, keep in mind that the color of the coolant does not necessarily indicate whether or not it is the proper coolant for your vehicle. There are other brands that are developed for certain automobile models and countries of origin, and they can come in a range of colors that can be difficult to distinguish.

Go to the Source

The owner’s manual for your automobile contains a plethora of information. It will inform you as to which sort of coolant is the most appropriate for your car. Unless you have a copy of the handbook for your vehicle, you will most likely be able to obtain the information you want online. The formulae indicated at your dealership and in your owner’s manual are almost certainly authorized by the original equipment manufacturer (OEM), but there are likely aftermarket alternatives available as well.

Don’t Forget the Water

Read the label on the bottle of coolant before changing it to determine if the formula has to be mixed with water before changing it. Some varieties of coolant may be poured directly into your vehicle’s cooling system without the need for an additive, while others are meant to be mixed 50/50 with water. Water from the tap that has been softened will suffice. Because the performance of your automobile is important to you, it is important that you measure the ratio accurately. Creating a coolant that is either too weak or too powerful might lead to poor performance on the part of the engine.

Here’s a brief advice to keep in mind if you ever find yourself in a bind.

How Can I Best Protect My Car’s Engine?

Check the label before replacing your car’s coolant to check if the recipe requires mixing with water before you begin. Depending on the kind of coolant used, some can be poured directly into the car’s cooling system without the need for an additive, while others must be mixed 50% with water. It is sufficient to use softened tap water. Because the performance of your automobile is important to you, it is important that you measure the ratio with care and accuracy. It is possible to get poor performance out of a coolant if it is either too weak or too powerful.

If you ever find yourself in a situation where you need to act quickly, consider the following advice. Using water to help you make it to the next auto shop or gas station if your car’s coolant level is low is a good idea.

Choosing the Right Coolant for Your Car

Checking your coolant level is easy to overlook, yet coolant is just as crucial as oil in an engine when it comes to your car’s performance. Coolant does raise the boiling point of the cooling system in the summer and reduce the freezing point of the cooling system in the winter, as well as protecting the engine and cooling system from corrosion. When driving in adverse weather conditions, these features prevent the engine from overheating or freezing completely. Coolant has to be changed because the chemicals in the coolant degrade and become less effective over time, requiring replacement.

It is possible that the cooling system may become damaged, resulting in the engine overheating, which is a considerably more expensive mistake than paying for a coolant flush.

Finding the Right Fluid

Lubo Ivanko is a professional wrestler. Photographs courtesy of Getty Images When it comes time to top off your coolant or do a total system cleanse, you’ll need to be sure you’re using the proper coolant for the task. However, while it would be nice if all manufacturers utilized the same coolant, this is not the case. Automobile manufacturers utilize three types of coolant: inorganic additive technology (IAT), organic acid technology (OAT), and hybrid organic acid technology (Hybrid Organic Acid Technology) (HOAT).

  • It must be replaced every two years or 24,000 miles, making it significantly less efficient than current formulae.
  • The General Motors formula is used in their automobiles, and they typically require a replacement after five years or 50,000 miles.
  • The quickest and most reliable approach to ensure that you’re obtaining the proper coolant for the task is to visit the dealership where you purchased your vehicle.
  • Many times, the coolant is actually labeled with the name of the vehicle in which it will be used.
  • Many other companies, such as BMW and Volkswagen, do the same thing.
  • All General Motors vehicles are equipped with something called Dex-Cool right out of the box.
  • Remember that practically every current jug of coolant you’ll come across has been pre-diluted, so be cautious while using it.

Back in the day, coolant was always sold as a concentrated solution, and you had to dilute the liquid yourself with water. Of course, pre-diluted coolant is more convenient, but you wind up spending significantly more for significantly less fluid.

Going Colorblind

HaugedPhotos from Getty Images In addition to the original equipment manufacturer’s selections, auto parts retailers will sell a variety of aftermarket coolant brands. Companies such as Prestone, Pentafrost, Peak, and others all provide versions of their products that they claim are effective for certain brands or nations as a whole (the country a car is made in is typically a good predictor for which coolant type it takes). Most of the time, these aftermarket solutions are less expensive than original equipment, but it’s worth it to invest in genuine original equipment coolant built specifically for your vehicle.

  1. Despite popular belief, colour is not a good indicator of the type of coolant you are using.
  2. The majority of HOAT coolants are orange and yellow in coloration.
  3. The coolants that manufacturers supply, such as Honda’s blue coolant, might further complicate problems by creating confusion.
  4. If the bottle’s description leaves you perplexed, consult your owner’s handbook to determine the proper type of coolant to use.
  5. Therefore, keep track of the coolant you used and when you used it so that you’ll be prepared when your engine ultimately requires flushing a few years down the road.

45 responses to “Which Antifreeze Color Should I Use?”

The term “antifreeze” is definitely something that you’ve heard spoken in connection with your automobile, but you may not be familiar with what this liquid is or how it works. Avoiding antifreeze is detrimental to the function and durability of your vehicle, and you should avoid doing so. The ability to recognize what antifreeze is, where it is used, and how to properly maintain it will help you avoid major engine problems down the line. Visit Tom Kadlec Kia in Rochester, Minnesota, to learn more about auto maintenance and repair.

What is Antifreeze and How Does it Work?

Image courtesy of robineero on Unsplash. Antifreeze is a necessary engine coolant that aids in the regulation of engine temperatures in your vehicle. 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.

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 automobile professionals, even the terms 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 mixture of antifreeze and water that is installed in your vehicle. It is the ethylene glycol or propylene glycol component of this mixture that acts as an antifreeze. As a result, an antifreeze product that does not contain 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 substance that lowers the freezing point of water.

This distinction is extremely minor, and the majority of people will understand you regardless of whether you refer to the product used to cool the engine in your vehicle 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.

  • 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?

If your antifreeze level is just a tad low, you may quickly top it off with a few simple steps. To apply antifreeze to your car, simply follow these steps:

  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.

Place the car on level ground and allow it to cool fully before starting it up again if necessary. In order to provide additional safety, use the parking brake on your car; It is necessary to check the label on your antifreeze to see if it is necessary to mix it with water or not. It is possible to inflict major harm to your vehicle’s radiator by adding unmixed antifreeze. Whenever 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 exterior of the tank.

4 Different Types of Coolant and Their Colors (Don’t Use the Wrong Type!)

The most recent update was made on December 29, 2021. The gasoline or diesel engine in your car or truck generates the required power to propel you forward down the highway or highways. The engine also generates a significant quantity of waste energy in the form of heat, which must be disposed of properly. And that heat must be removed from the internal systems of the engine and efficiently discharged to the atmosphere outside the engine. Are you looking for a reliable online repair manual? The top five choices may be found by clicking here.

With the exception of an ancient VW Bug, a Chevy Corvair, or a Porsche, the engine of your automobile will be “water” cooled.

What is the mechanism through which all of this operates?

The hoses are responsible for transporting this fluid. The water in the radiator absorbs heat from the engine and dissipates it into the air going through the radiator with each drive. Your engine will not overheat as a result of this.

What is Engine Coolant?

The term “water” is used to refer to the cooling fluid in the preceding description. However, the cooling fluid will not be simply water, but instead be a mixture of water and antifreeze. This combination is referred as as coolant in the technical world. To put it another way, coolant is the liquid that serves to keep the engine of your automobile cool. To have a complete understanding of today’s automobile coolants, we must first consider the characteristics of the pure water that was originally employed for this purpose.

  • It has a very high specific heat value, making it extremely efficient. That is, water can contain more heat per unit volume than practically any other fluid
  • It has a relatively high boiling point
  • It is readily available virtually everywhere at a surprisingly cheap cost
  • And it is available virtually everywhere at a wonderfully low cost.

There is little doubt that these three characteristics contributed to the popularity of water as a coolant in the early 1900s, when engine-driven vehicles first appeared on the market. However, there are a number of issues with utilizing water alone that made it less than the ideal engine coolant at the time and continue to be so now.

  • Water has a freezing point of 32 degrees Fahrenheit, making it unsuitable for use in engines in most high-latitude regions around the globe. What’s more, when it freezes, it expands, making it unsuitable for use in engines in most high-latitude climates around the world. This type of behavior can cause any engine that is only cooled with water in the winter to fail. Furthermore, it can cause a radiator to freeze within, causing that expensive component to be easily destroyed. In the case of the materials usually used in engines and radiators, water accelerates corrosion (which results in the formation of metal oxides or rust).

How Do You Add Water to Your Radiator in an Emergency? Related:Can You Add Water to Your Radiator in an Emergency? Chemists began modifying water with the addition of chemicals very early in the creation of engines in order to make it a more acceptable coolant for the engines. These additions were designed to address both the problems of water outlined above as well as the benefits that water brings to the table in terms of maintaining a cool environment. Also see: How Does a Radiator Coolant Overflow Tank Function?

Making Water the Ideal Coolant

It was coolant freezing that was the most difficult challenge to solve early in the history of engine cooling. And it wasn’t long before chemists discovered that methyl alcohol (methanol) could be added with water to reduce the freezing temperature. Methanol was the first antifreeze addition to be discovered in a coolant additive. Unfortunately, this antifreeze also decreased the boiling point of water, putting a new and serious problem into the equation. The boiling point of fresh water is 212 degrees Fahrenheit.

  1. As an antifreeze, the lower boiling point achieved by utilizing methanol could not be accepted.
  2. It reduced the freezing point of water, however it was only effective down to a temperature of -36°F.
  3. It was necessary to create an even better product.
  4. A petroleum-based derivative called ethylene glycol was discovered in 1926 by scientists, and it has shown to be a long-lasting solution.
  5. Ethylene glycol has replaced ethylene glycol as the preferred antifreeze for internal combustion engines.
  6. As a result, when added to water, the amount of heat that can be retained by a given volume of this coolant mix is lowered.
  7. Furthermore, pure ethylene glycol has a pleasant flavor to it in addition to being poisonous.

It’s possible that your next-door neighbor’s dog may be drawn to the flavor and will eat it, resulting in tragic results.

It is also effective as an automobile coolant when used in conjunction with propylene glycol, which is a second and more modern antifreeze alternative.

When employed in coolant mixes, however, it is more susceptible to the development of bacterial and fungal growth over time.

As part of an effort to reduce the toxicity concern, antifreeze producers in the United States decided to include a bitter-tasting ingredient in their antifreeze products in 2012.

As a result, the range of applications for propylene glycol has expanded.

Antifreeze producers utilize patented chemicals to extend the life of their antifreeze, reduce corrosion, improve the efficiency of their water pumps, and reduce foaming.

A secondary advantage of using this chemical is that antifreeze leaks are generally quickly identifiable with a sensitive nose, which is particularly useful in winter. Related:Losing Coolant Despite the Absence of Visible Leaks

Does It Matter What Coolant I Use?

Yes, it very certainly does. Your automobile’s or truck’s owner’s handbook will provide you with particular instructions in this respect. Disregarding this warning might potentially result in a costly repair bill only a few kilometers down the road.

Different Types of Coolant

The antifreeze sold by one well-known auto parts retailer is available in 17 distinct varieties for vehicles and trucks. In this section, we will make an attempt to condense this bewildering assortment into the most fundamental sorts of antifreeze and antifreeze colors that you can expect to find on store shelves. Apart from that, you will have to pick between full strength antifreeze and a 50-50 blend of antifreeze and water. It is necessary to mix full strength antifreeze with distilled water before using it in your vehicle’s cooling system.

  1. In extremely cold weather, a 60-40 mixture of antifreeze and water can be utilized to give lower temperature freeze protection while still maintaining high performance.
  2. Drinking water contaminated with dissolved chemicals and/or chlorine can cause major cooling system difficulties if not treated properly.
  3. In addition, never replenish an empty cooling system with 100 percent antifreeze, i.e., antifreeze that has not been mixed with any additional water.
  4. Let’s go through the different colors and kinds of antifreeze.
  5. This can assist us in avoiding the addition of the incorrect coolant.

1 – IAT (Inorganic Acid Technology)

Bright green is the most common color. This is the oldest coolant mix available, and it was used by all domestic automobile manufacturers until around 1994, with some manufacturers, such as Ford, continuing to use it until 2002. This mix was no longer used by Asian and European automobile manufacturers after 1990. It includes phosphates and silicates, and it performs admirably with cast iron engine blocks and copper or aluminum radiators, among other things. IAT coolants must be cleansed and replaced every 2 years or 36,000 miles, whichever comes first.

Years ago, if this coolant was not updated on a regular basis, it was not uncommon for heater cores to become clogged.

2 – OAT (Organic Acid Technology)

Colors that are commonly used include orange, red, blue, and dark green.

This type of coolant does not include any phosphates or silicates and may be found in the majority of American automobiles manufactured after 1994. These coolants have a longer service life of up to 5 years or 150,000 miles, which is a significant advantage.

3 – HOAT (Hybrid Organic Acid Technology)

Colors that are commonly used include yellow, turquoise, pink, blue, and purple. These coolant mixes are classified as Hybrid Organic Acid Technology (HOAT) products because they fall in between the IAT and OAT categories. HOATs are often found in recent Chrysler models, as well as in European and Asian automobiles, among other places.

4 – Dex-Cool

Orange is the most common color. Dex-Cool, a form of OAT, was invented in 1995 for General Motors automobiles. Blockages were commonly experienced by owners who made the mistake of adding green coolant to systems that incorporated the Dex-Cool technology. While Dex-Cool is a suitable coolant in all other aspects of its use, it must never be blended with any other forms of antifreeze.

Carmaker Branded Antifreeze

Going to the dealer parts counter for antifreeze for a late-model car, whether domestic or foreign, may be your best choice for antifreeze. You will avoid having to read the antifreeze specifications and/or usage restrictions on those gallon jug labels at the parts shop if you do it this way. While you may have to spend a little extra, you’ll have the peace of mind knowing that you’re using a coolant mix that was particularly designed for your vehicle.

What Type of Coolant Does MY Car Need?

Your vehicle was sent from the manufacturer with the specific type of coolant it required to function properly. Throughout its service life, the same type of coolant should be utilized. Your owner’s manual will tell you what sort of vehicle you have. Alternatively, if you need to acquire antifreeze, you may get this information from a qualified auto parts professional.

Can I Mix Different Coolants?

Your vehicle was sent by the manufacturer with the specific type of coolant it required to operate properly. This particular coolant type should be utilized for the whole life of the machine. If you have an owner’s manual, you will find out what type it is. Alternatively, if you need to acquire antifreeze, you may get this information from a skilled auto parts professional.

Can I Add New Coolant to Old Coolant?

Your vehicle was sent by the manufacturer with the specific type of coolant it required to run properly. For the duration of its service life, the same type of coolant should be utilized. Your owner’s handbook will tell you what sort of engine you have. If you need to acquire antifreeze, skilled auto parts professionals can also assist you with this information.

  • The new coolant you are adding to your car’s cooling system must be the same type and color as the antifreeze already present in the system. Non-compliance with this guideline may result in costly engine damage.

Additionally, while adding coolant, you should always use a pre-mixed 50-50 combination of antifreeze and antifreeze concentrate. The majority of automobiles currently have a 50-50 mix installed. As a result, the addition of this fresh coolant blend will have little effect on the freeze and boil-over temperatures.

What Can Happen if I Use the Wrong Type of Coolant?

Using the incorrect antifreeze in your cooling system might result in coagulation of the coolant and blockage of the radiator or the entire system, among other problems. If the system is significantly blocked, it may not be possible to flush it and it may be necessary to completely disassemble it in order to decontaminate it.

An Important Caution with Pre-Owned Vehicles

Consider the following scenario: you have recently purchased a pre-owned vehicle that is five years old or older and/or has more than 150,000 kilometers on the odometer. The first servicing work you should perform on this vehicle should be a full cooling system drain and cleanse, followed by the installation of the proper fresh coolant.

It’s possible that you have no clue whether or not such a service has ever been performed on your ‘new’ automobile. You would be making an exceedingly sensible decision by taking this step.
