Competent selection of antifreeze according to car make

How to choose antifreeze for a car, review of brands by color, composition and properties

The most important characteristic of the refrigerant is the temperature of crystallization/thickening due to exposure to negative temperatures. Any of them contains special additives. They reliably protect the motor from harmful phenomena:

• Corrosion;
• Reduced elasticity of rubber parts;
• Cracking;
• Increased wear.

Antifreeze can only freeze at very low negative temperatures. Usually at this moment a mushy mass forms that does not affect the operation of the engine.

What does antifreeze consist of?

It is based on:

• Polypropylene glycol;
• Water;
• Additives.

Thanks to the original properties of additives, antifreeze acquires special qualities:

• Anti-corrosion;
• Never foams;
• Doesn't freeze.

Antifreezes are manufactured by foreign and Russian manufacturers. An original additive package is added to each composition. That is why the quality of the product, as well as its composition, are never the same.

Classification

The largest German company Volkswagen has developed a classification of antifreeze specifically for its production. Depending on the action of the additives, they were divided into groups:

Today, all cooler manufacturers use this classification.

G11

The cheapest antifreeze. It is based on ethylene glycol, together with a minimal package of additives. Made of silicone, they form a thin layer on the walls of the cooling channels, protecting them from corrosion. G11 is poured mainly only into domestic cars. Designed for 2 years of operation.

G12

It contains no nitrites. The refrigerant is made from high-quality ethylene glycol with the addition of carboxylate compounds.

The thin film formed by antifreeze appears only in certain areas where there is a risk of corrosion processes. At the same time, heat removal from the system increases.

If corrosion occurs, it is quickly localized with carboxylate additives.

This cooler is very effective in machines equipped with a high-speed motor operating at high temperatures. A complete replacement of G12 antifreeze is carried out after five years.

G12+

Non-toxic polypropylene glycol is used for production. This is the safest composition that meets all environmental requirements. Special components - additives - make it possible to pour such antifreeze into aluminum or cast iron engines.

G12++

A universal brand that does not contain phosphates (quite harmful substances). Compatible with older types of coolers. Designed for vehicles operating at elevated temperatures.

What colors does antifreeze come in?

Since the range of coolants is quite large, manufacturers paint them in a certain color that characterizes the existing properties.

Green

An inexpensive coolant containing additives of organic and inorganic origin. This shade is typical for representatives of the G11 brand. It has better characteristics than regular antifreeze.

Used in older cars manufactured before 1996. It has anti-corrosion properties, creating a protective film. Requires replacement maximum once every three years.

Varieties are also available - G11+ and G11++, with an improved composition of additives.

He's antifreeze. At low temperatures it freezes and contains a minimum amount of additives dating back to the first generation manufacturing method. They contain various inorganic compounds, including phosphates, nitrites, silicates, nitrites, which form a thin protective film.

Due to the aggressiveness of the composition, it is considered obsolete, especially when taking into account the rather “low” boiling point - 110 Celsius. The fact is that for many modern internal combustion engines, these temperature indicators (or even higher) are working.

Red

G12 antifreeze is painted this color. It has improved performance compared to other coolants. Used in cars manufactured from 1996 to 2001.

The composition is dominated by organic additives. The refrigerant creates a durable, non-crumbling protective film and fully fights corrosion (but does not protect against it).

Does not require replacement for a long period of up to five years.

Orange

The color indicates high quality and excellent environmental properties. The stamps are painted in this color:

That is, these are subtypes of red antifreeze. It is one of the most expensive samples, but the cost is fully compensated by the quality. Contains maximum organic additive components. Designed for use in the latest vehicles operating in harsh conditions.

How to choose antifreeze

Choosing the right refrigerant is quite difficult. The manufacturer usually indicates its brand in the technical documentation.

If you decide to use an analogue, be sure to read the label, which contains important information, of which the most relevant:

• Name;
• Date of manufacture;
• Best before date;
• Where it is applied.

The container must be closed with a stopper with a disposable ratchet. No sediment is allowed at the bottom of the canister; the composition must be absolutely transparent.

Selection of antifreeze by car make - not only this factor should be taken into account

Coolants are presented in such a wide range that it is easy for the average car enthusiast to get confused about them. Different companies, colors and prices can be confusing: which antifreeze should you choose for your car? Let's try to figure it out.

• Sheinin: “I speak for myself, anyone can cure prostatitis, take the proven Prost...”

Selecting antifreeze by car brand is, in fact, not a very correct approach; the characteristics of the purchased composition are more important. All modern coolants are based on 80% alcohol and distilled water, the remaining 20% ​​are various additives. The alcohols used are ethylene glycol and propylene glycol.

They differ only in price and toxicity: propylene glycol is less toxic and costs more. Otherwise their properties are identical. Pure alcohols are aggressive towards metals, especially aluminum alloys from which modern engines are made.

For this reason, additives are added to the coolant to eliminate the aggressiveness of alcohols.

• They will protect the chassis and save you money, increasing ground clearance by 3 cm.

The classification of antifreeze depends on the types of chemical additives. The most widely used classification of Volkswagen engineers is:

1. G11 – ethylene glycol plus silicate additives. Chemical additives form a thin film on the metal, which protects it from destruction. After a year or a year and a half, it begins to deteriorate and, traveling inside the engine, acts like an abrasive. Suitability is maximum 2 years.
2. G12 - basically the same, but the additives are higher quality carboxylate. A protective film is not formed; additives react to pockets of corrosion, instantly blocking them. Service life 3 years.
3. G12+ and G12++ - ethylene glycol with organic and inorganic hybrid additives, have absorbed the best qualities of the previous two. Does not lose properties for 5 years.
4. G13 – antifreeze with propylene glycol alcohol and hybrid additives, lasts 5 years.

To choose antifreeze, you should know the requirements for it:

• boils at a temperature of at least 110°;
• the freezing temperature corresponds to the climate of the region;
• minimal foaming and viscosity;
• high-quality additives that reduce the aggressiveness of the liquid to zero;
• long service life.

Only leading manufacturers paint antifreeze in classic colors, so you should choose not by color, but rather by the year of manufacture of the car. Until a certain time, blocks were made of cast iron and other alloys that were less susceptible to corrosion.

Therefore, we can roughly recommend antifreeze with a coefficient of 11 for cars produced before 1996, 12 before 2001, 12+ and 13 after 2001. Typically, global automobile companies recommend a brand of antifreeze. European and American companies use G11 for budget cars, and G13 for expensive cars.

The Japanese and Koreans are uploading their own products, similar to G12+. Russia and the CIS pay almost no attention to this.

In order not to harm the car when changing antifreeze, you should try to choose products from the same manufacturer, with the same color.

The quality of European and American coolant from Shell, Texaco, Total is recognized by everyone.

True, today a brand does not guarantee quality: the market is full of counterfeits, and if they engage in counterfeiting, they focus on well-known companies. The main thing when choosing is to buy and fill a quality product.

Of the domestic brands, car enthusiasts appreciate the products of Felix, Nord, Alaska, and Sintec for their quality and cheap price compared to foreign analogues. Felix and Sintec belong to the G12 category and have proven themselves well on modern engines. Nord antifreeze is presented in categories G11 – G13 and operates from -50 to +110°. Alaska is the best antifreeze in the G11 category.

SELECTION OF ANTIFREEZE BY YEAR OF PRODUCTION AND CAR MAKE

Car enthusiasts who have been using their vehicles since Soviet times are well aware that in the USSR, perhaps only one liquid for cooling a car engine has become widespread - the famous “Tosol A40”.

However, the service life of this antifreeze, unfortunately, left much to be desired. In addition, antifreeze served as a source of a number of harmful deposits on car elements. Today, instead of antifreeze, more technologically advanced antifreezes such as mixes, lobrida, etc. are increasingly used.

These types of antifreeze liquids can be mixed if necessary.

Many owners of “iron horses” often ask the question: “How to choose antifreeze according to the make of the car?”

Differentiation of coolants by car brand

Currently, many types of antifreeze are available in car dealerships and car markets. For the first time, their marking according to functional characteristics (WG classification) was introduced by the auto giant Volkswagen, establishing gradations that you can see in the catalog “G11”, “G12”, etc.  

It is worth considering that not all antifreezes can be used for a particular make/model of car. Any “iron horse” has its own technical passport, which contains recommendations for operation, including what kind of coolant this car needs.  

If any difficulties arise during the selection process, it is better to contact a specialized car service center, where specialists will help you choose exactly what is required, taking into account the time of year, weather conditions, driving style and other significant factors.

The first thing you should pay attention to when buying coolant for a car is the digital index on the packaging, printed after the letter marking “G” or “Godeg”. The set of numbers encrypts information about the class to which the vehicle belongs. The more recent your car is, the higher the numbering.

So, for cars manufactured before 1996, coolant number 11 is used (usually blue and green), and antifreeze number 12 (red) can be used in cars manufactured after 1996.

Antifreeze marked 12+ is poured into the cooling system of cars manufactured after the year 2000.

If the engine is particularly powerful (sports car, truck tractor, etc.), antifreeze number 13 is suitable for it.

Choice for vintage cars

Along with W: G11, G12, G12+ (Plus), there is another well-known European antifreeze classification - BS 6580 (British Standard). G11 and British Standard are equivalent, having a bluish, yellowish or greenish tint.

They are used for old cars (up to 1996), do not contain chemical elements in the form of nitrites, borates, etc. and do not leave scale, which increases the life of the engine cooling system. Such antifreezes must be replaced every 2 years.

Antifreezes designated G12 do not contain silicates that cause corrosive destruction of non-ferrous metals. They can be replaced every five years.

Similar coolants are used for cars from 1997–2001. production. Their color range ranges from pink to purple. For older cars manufactured before 1996, you can use mixtures of antifreeze created in the late 80s - early 90s.

But in cars manufactured since the beginning of the 3rd millennium, only antifreeze brands should be used that do not comply with the new marking - TL 774-D.

The choice of antifreeze for modern cars

It should be borne in mind that, in addition to the traditional types of coolants that have already become widespread, in recent years chemical companies have begun to produce coolants specifically designed for a particular brand of car.

They cost a little more than regular antifreeze, but this is compensated by their high quality and longer service life. Such products are usually sold in the form of concentrates, diluted when used with distilled water in the required proportions (in the central zone of the Russian Federation - usually 1:1, in regions with a harsh climate - in a higher ratio).

The concentrate packaging contains detailed instructions for its use.

1. Liqui Moly antifreeze concentrates

These coolants are most often used for Volvo, MERCEDES, VOLKSWAGEN and many others. This coolant meets a wide range of machine tolerances and is a universal fluid for any cooling system.  

Made on the basis of monoethylene glycol with the addition of a number of additives, they provide reliable protection of the car engine from overheating and freezing, increasing the frequency of replacement. Concentrates can be used at temperatures down to -45 °C.

For more details, see the full range of liquids in the Liqui Moly antifreeze catalog, where you can verify the quality of the liquids, because the abundance of approvals and specifications confirms this.

There are even permits for trucks, which indicates technological additives and additives that work even at extreme temperatures. 

2. Audi antifreeze concentrate

This coolant also does not contain phosphates, silicates and other substances that contribute to the formation of scale. It is ideally suited for use in new Audi engines with aluminum parts.

Antifreeze has excellent cleaning and lubricating properties and is intended for use in Audi cars of the entire modern model range.

3. BMW antifreeze concentrate.

For cars of this brand, BMW branded concentrate is used.

Such a liquid is specially “tailored” for the cars of this German concern and is capable of reliably protecting all elements of the engines used in them from chemical destruction, ensuring the possibility of comfortable driving even in extreme temperature conditions.

When choosing any type of coolant, pay special attention to the instructions for its use. Be especially careful to follow the proportions recommended by the manufacturer. In this case, your “iron horse” will never let you down. Good luck on the roads!

The best antifreezes, top 10 rating of good antifreezes 2018

Coolant is very important for any car. If it is chosen correctly, the engine will not overheat due to excessive loads.

This rating presents only high-quality products.

We analyzed the preferences of many users and compiled the top 10 best antifreezes in terms of price and quality that can be found on the Russian automotive goods market.

What to look for when choosing antifreeze?

Antifreeze should not boil or freeze during use. All these compounds can be divided into several groups, according to the generally accepted international classification:

• G11 is blue or green in color. They have the shortest service life - only 2 years;
• G12 are painted in red, pink or purple, the service life of the liquid is up to five years;
• G12+ are a variation of the previous group with only one feature - they can be mixed with any other coolants.
• G13 are modern, harmless coolants based on polypropylene glycol. Appeared in 2012.

When purchasing, pay attention to the appearance of the packaging. It is very easy to identify a fake by the following criteria:

• Too cheap price;
• Presence of sediment;
• Strong or unpleasant odor;
• There is no pH value in the description;
• The packaging is of poor quality, it is clear that it was printed under artisanal conditions.

During operation of the liquid, you need to carefully monitor its condition. If it changes color, this will indicate certain problems in the cooling system or a low-quality composition.

How to choose the right antifreeze?

Most motorists perform such a procedure as selecting antifreeze quite carelessly. But in vain. Every car owner should value his vehicle, and therefore constantly monitor its technical condition, promptly replace consumables and repair it.

Priority attention should be paid to the power unit as the main component of the vehicle. It is clear that it is necessary to fill engine oil in a timely manner and use only high-quality gasoline, but do not forget that the engine operates in conditions of very high temperatures. The most important nuance is high-quality cooling of the power plant.

But here the main role is played by antifreeze, which is a coolant.

Antifreeze selection criteria

Antifreezes on the automotive consumables market are presented in two types: ready-to-use (diluted) and concentrated. The choice of antifreeze should be made based on the instructions of the automobile manufacturer. You can find out about them by reading the instructions in the service book.

Unfortunately, many motorists, even experienced ones with many years of experience, do not pay due attention to the selection of antifreeze for their cars. But statistics, although not an exact science, are stubborn, and they say that 40% of malfunctions in a car’s internal combustion engine occur precisely because of the use of low-quality antifreeze.

The main criteria for choosing antifreeze that you need to take a closer look at are the following:

– fairly high heat capacity;

– thermal conductivity;

– low crystallization temperature.

In addition to the main above-mentioned criteria, antifreeze should not expose the metal to corrosion (this is achieved thanks to special inhibitor additives), and also should not form foam during operation of the power unit.

When choosing a coolant, also consider the year of manufacture of your car. The later it came off the assembly line, the higher the class of antifreeze being poured should be.

So, for example, cars that were produced up to and including 1996 consume coolant marked 11. From 1996 to 2001 - 12. Cars after 2001 are serviced with antifreeze class 12+.

There is also marking 13, but this liquid is intended for extremely severe operating conditions of an internal combustion engine.

Which antifreeze to choose

Firstly, when starting to select a high-quality coolant for a car engine, check in the vehicle passport which class should be used.

The best option would be to purchase antifreeze at a specialized point of sale or service. In such places, sellers know the product very well and will select exactly what you need.

So, which antifreeze should you choose if you purchase the product yourself?

When choosing antifreeze, immediately pay attention to its container. According to the standard, it must be transparent so that the buyer can inspect the contents for any particles or sediment. They shouldn't exist. The container must be completely sealed. Pay attention to the lid. It's a good sign if it's special. The label should be as informative as possible, indicating the following components:

– company – manufacturer of antifreeze;

– date of manufacture;

- life time;

– the main composition of the liquid.

As a rule, manufacturing companies indicate the crystallization temperature of the coolant on the product labels. For example, Coolant-40, Coolant-65, Antifreeze A-40 and others. You shouldn't have any problems with this.

Pay special attention to additives added to antifreeze: inhibitors - non-corrosive, non-foaming and stabilizing.

If these are not present, the parts of the motor system will simply collapse over time.

Coolants manufactured overseas are required to meet ASTM (American Association for Testing and Materials) and SAE (Society of Automotive Engineers) standards. Antifreezes made on the basis of propylene glycol are less toxic, but, accordingly, are much more expensive.

With the purchase of a good and high-quality “anti-freeze” you will forget about engine problems that arise in different seasons. The main thing is to avoid fakes. Remember all the nuances described in this section. Look at the quality of the canister and how the label is attached.

Such pedantry will save your nerves and extend the “life” of your car’s engine.

Why do antifreeze come in different colors?

Many people know that coolant differs visually and in color. There is an opinion that the color of antifreeze somehow affects its properties - this is not true. Dyes are added by manufacturers to the liquid only to mark its various types.

For example, you use coolant from one manufacturer, which means that for ease of selection it will be easier to focus on its color.

Each brand of antifreeze uses its own color marking system, so if you decide to purchase a liquid of the same color, but from a different manufacturer, it is better to carefully study its characteristics indicated on the container.

As we have already discussed above in this section, the color of antifreeze changes only depending on the addition of a dye of one color or another to it. Technological progress is moving ever further.

Not only are various production technologies and formulas being developed that determine the quality of antifreeze, but also the marketing component.

In this economic sector, a new solution has begun to be used in the competitive struggle to attract consumer attention specifically to their product. Here is another reason why antifreeze can be of different colors.

For example, such automotive giants as Audi, Volkswagen and GMC produce anti-freeze products with enhanced technical characteristics. The service life of such a liquid reaches 200 thousand kilometers. Of course, to make it stand out from others, it is painted an aggressive bright red color. no mistakes

Catalog

During the 2018 World Cup game days, we may take a little longer to deliver goods than usual.

Stable and normal operation of a car engine in the cold season is impossible without high-quality coolant. The freezing point of antifreeze is much lower than the freezing point of water. The main function of the coolant is to reliably protect the engine from corrosion and mechanical damage that can be caused to the engine by frozen water.

As the coolant freezes, its consistency becomes jelly-like.

However, to achieve such a state, a fairly low subzero temperature (about -35 degrees) will be required, which is the main criterion for choosing a product.

Depending on the brand of coolant, the composition will be determined: a specific set of additives that prevent corrosion; rubber gaskets provide elasticity of the elements and prevent their wear.

Compound

Regardless of the manufacturer and specification, we will highlight the main components of the liquid:

1. All existing products can be produced on the basis of two elements: ethylene or propylene glycol with water. It is best to give preference to the second option, because the combination of water and propylene glycol is environmentally friendly, as they are made from environmentally friendly components.
2. A complex of special additives that protect the engine from corrosion and also minimize the amount of foam;
3. Dyes that contribute to obtaining a particular color of a liquid.

Each manufacturer of cooling products reserves the right to add a certain set of additives that determine the quality and composition of antifreeze. That is why you can find a fairly wide variety of these products on the modern market.

Characteristics by color

Many inexperienced motorists are interested in the question of why does the manufacturer paint a bleached liquid a certain color? This is done for one simple reason - consumer convenience. Thus, a certain color of a product indicates its technical characteristics, composition and quality:

• Green. The most budget-friendly option for cooling products, to which the manufacturer has added a minimum amount of additives. However, compared to antifreeze, green antifreeze has better characteristics;
• Blue color indicates that the liquid freezes at lower temperatures than its green counterpart. The blue product's manufacturing process uses relatively small amounts of additives;
• Red color has higher quality, temperature and technical characteristics than green and blue varieties;
• Orange or yellow color indicates increased quality and environmental properties. This type of product tends to be more expensive, but will also last longer.

An important and interesting nuance is the fact that the use of green and blue antifreeze is recommended only for cars that were produced before 1996. Red color is recommended for cars produced in 1996-2001.

But yellow or orange liquid is mainly used for modern car brands. The high-cost coolant has found wide application among drivers who prefer extreme driving.

G12++	Relatively recently, a brand of antifreeze appeared on the modern automotive market under the number G12++. The liquid is a cross between silicate and carbosilicate compounds. The manufacturer does not use harmful and toxic components, including phosphates and borates. Best protects the car engine cooling system. Crystallization begins at temperatures less than -35°.	G12++ is most suitable for use in engines with high air circulation rates.	Operational period from 4 to 5 years.	Color – orange or yellow.

When is it necessary to replace antifreeze?

There are several rules according to which the coolant is replaced:

• Loss of color or dark brown color of the product;
• The appearance of sediment;
• A gel-like coating has appeared on the walls or neck of the expansion tank.

Remember that antifreeze changed at the wrong time not only loses its positive properties, but can also cause damage to the mechanical parts of the engine and cooling system.

In order to choose the most suitable brand for your car, you should consult with a specialist or open the technical passport of your car. Also, each coolant manufacturer indicates all the necessary parameters, technical and quality characteristics on the packaging of their product.

Criterias of choice

When purchasing a product, inspect the container or canister for damage. The lid must be tightly and hermetically closed. When you open the canister, you will hear a specific click, which indicates the integrity of the seal.

The labels must contain information regarding the country and manufacturer. Be sure to check the production date and expiration date. After opening the canister, look for sediment at the bottom.

The rising foam should disappear within five seconds.

By choosing high-quality antifreeze, your car's engine will be reliably protected from corrosion and mechanical damage that can be caused by frozen water.
