Antifreeze in the car: what is it for, basic parameters, review of popular RFs for VAZ 2109-2115, recommendations for combining different antifreezes

For diesel and gasoline engines the parameters will be the same!
When purchasing, you need to know the shade - Color and Type of antifreeze allowed for the year of manufacture of your 2109. Select the manufacturer at your discretion. Do not forget - each type of liquid has its own service life.

For VAZ 2109 (1st generation) 1987, with any type of engine, the traditional class of antifreeze, type TL or antifreeze with shades of blue is suitable. The approximate period of the next replacement will be 2 years.

If possible, check the selected fluid against the vehicle manufacturer's specifications and service intervals.

Each type of liquid has its own color. There are rare cases when the type is tinted with a different color. The color of red antifreeze can be from purple to light pink (green and yellow have the same principles).

Antifreeze or antifreeze - what to choose

Before you find out what antifreeze to pour into the VAZ 2114, you should figure out how, exactly, antifreeze differs from antifreeze? And why can’t they be poured into one system at the same time?

To put it quite simply, dividing coolants into antifreeze and antifreeze is not entirely correct. After all, antifreeze is also one of the varieties of the latter. The point here is that classic antifreeze was developed specifically for VAZ cars and, despite the composition being very close to modern antifreezes, it has a different density.

The presence in the cooling system of two solutions with different specific gravity (antifreeze and antifreeze) can lead to foaming and disruption of coolant circulation.

It is also worth noting that classic antifreeze (its category is marked with the symbols Tl) has a slightly more aggressive chemical environment, which can sometimes even lead to damage to the radiator (of course, with very long-term use of the car). In addition, an important difference between it and antifreeze is that the liquid sold in canisters is a semi-finished product.

In order to pour it into the car’s cooling system, you should dilute it with distilled water in a certain proportion (based on the expected negative ambient temperature).

Currently, the most common categories of coolant are:

Speaking about which antifreeze is best for the VAZ 2114, we can say with confidence - the G11 category. It has a more inert composition from a chemical point of view and is safer for the radiator and cooling system. In addition, it is much more common at present than antifreeze of the classic composition, so there will be no problems with its purchase.

Antifreeze for VAZ 21099

In general, blue coolant, if it is original, will be of sufficient quality. This antifreeze is optimally suited for use in internal combustion engines of passenger cars. This coolant contains additives designed to prevent the formation of foam and rust in the system. This consumable is based on monoethylene glycol, as well as purified water. The coolant is an inorganic liquid and fully complies with the G11 standard. Overall the refrigerant is quite good.

Felix green antifreeze

We will not describe Yellow Felix, since it is intended for heavy-duty engines, which our domestic cars do not belong to. As for green Felix, its main feature is corrosion resistance. If you believe consumer reviews online, this refrigerant reliably protects the internal combustion engine from overheating and hypothermia. In addition, this coolant is characterized by a high level of thermal conductivity. In the production of coolant, several stages of refrigerant purification are used, which is good news. Therefore, if in winter you have problems starting the engine, and in summer the unit periodically overcools, then it makes sense to think about switching to this coolant.

One of the key features of the red Felix is ​​that this coolant has a long service life of five years. That is, over the next five years from the moment you fill Felix, you don’t have to remember the need to replace consumables. In addition, it is resistant to scale, so you do not need to worry about the condition of the internal components of the cooling system. In any case, the purchase of consumables should be made in official stores, and not from sellers on the roadside, otherwise you may buy a counterfeit product, which will cause subsequent problems.

What categories of coolant can be mixed

Of course, the best option would be to fill the system only with liquids from one category, but if for some reason this is not possible, then you should use the following compatibility table:

1. Antifreeze Tl - only with antifreeze Tl.
2. G11 can be mixed with G13, G12+ and G12++.
3. G11 must not be added to G12.
4. G12 can be mixed with G12+, G++, G13.
5. G13 cannot be mixed with G12, but with other types it can.

Being guided solely by the color of the coolant when purchasing/refilling/replacing it is fundamentally wrong. Some manufacturers paint antifreeze and antifreeze in colors different from the generally accepted ones. The color has no effect on the chemical composition and density of the liquid.

You can learn more about how to replace the coolant in the video below (the author of the video is AvtoOR).

The cooling system is designed to ensure stable operation of the motor, which produces a lot of energy and constantly increases the temperature.

Coolant is a specific alcohol-based composition with additives that acts as a coolant.

Filling with coolant

Fluid replacement

If you plan to switch the car from antifreeze to antifreeze for any reason, then the old coolant should be drained by unscrewing the plugs in the block and in the radiator. It is worth remembering that this will not help remove the entire volume of coolant (and it is consistently equal to 7.8 liters).

In order to completely clean the entire system, you should fill it with ordinary water and drive the car for about 30 kilometers, after which you should drain everything again and add antifreeze. It goes without saying that this procedure can only be carried out in the warm season, but not in the cold.

It should be said right away that some motorists perform themselves and advise others to carry out additional procedures for cleaning the system of old coolant - adding vinegar, acetone and other additives to distilled water. It is strictly not recommended to carry out such operations. At best, they will be of no use; at worst, they can cause damage to the cooling system.

Antifreeze or antifreeze for VAZ-2109 and other models

Now let's look at this situation on more modern cars. So, what is better - Antifreeze or antifreeze for the VAZ 2109. Similar questions can also be included here: VAZ-2114 - Antifreeze or antifreeze, VAZ 2115 - Antifreeze or antifreeze.

Description and installation of the heater Start

The situation with these cars is similar to the VAZ-2107 model. That is, antifreeze is standard for these cars, but it is also possible to use antifreeze, but only of certain brands.

Replacing fluid on a VAZ-2110

As for the replacement procedure, let's look at how to replace Antifreeze with VAZ-2110 antifreeze or vice versa:

1. The car is installed on the platform and cooled;
2. The expansion tank cap is removed, the heater tap is opened, the plugs on the radiator and crankcase are unscrewed, and the waste fluid is drained into a container;
3. The plugs are installed in place and flushing liquid or distillate is poured into the system. The engine starts to circulate the fluid;
4. The flushing fluid is drained, and then fresh antifreeze or antifreeze is added;

On other specified models, the operation is performed similarly.

And as a result, we note that antifreeze is still better than Antifreeze in its properties, but it also costs more. If you want to take better care of your car, then you should fill it with antifreeze, but only of the appropriate brand. But a feature of our automobile industry is the possibility of system leakage, and replenishing the level of antifreeze can be expensive.

Antifreeze also does a good job, but it needs to be changed more often, but it costs less.

Which coolant to choose

Every motorist who wants to replace the entire coolant in the car system is interested in what kind of antifreeze to pour into the VAZ 2114? And which one is better not to buy? First of all, it’s worth saying that there are now a very large number of counterfeit coolants on the market, which can be easily recognized by poor-quality packaging and labels. In addition, you should always carefully read the name, which should indicate the category of the liquid.

As for brands and manufacturers, preference should be given to the following:

• CoolStream Standard – G11, green;
• CoolStream Premium – G12, orange;
• Lada Concentrate - category G11, produced either by Oil Center (Tolyatti) or Bulgar Lada Plus (Kazan);
• Lada A-40 - similar to Lada Concentrate, but supplied ready-to-use;
• OZH-65 TOSOL-TS - classic antifreeze, produced in the city of Dzerzhinsk;
• OZH-65 TOSOL-TORSA – G11, blue-green color;
• “Antifreeze G-48” – slightly green, G11. Previously produced in Perm, now rare.

How to replace antifreeze

Replacing antifreeze occurs in several stages:

For this operation, you do not have to contact specialists; you can easily do the work yourself. If you do not pay attention to this process, you may encounter the liquid changing color, becoming black, cloudy with an unpleasant sediment. All this is a consequence of rust and rubber decomposition. My advice for all owners of a VAZ 2109 car is to purchase coolant in a volume of about 8 liters, this way you can ensure that the old antifreeze is topped up or replaced on time. Take care of your car and then it will thank you with trouble-free operation.

Timing for replacing coolant in VAZ 2109

Replacing antifreeze on a VAZ 2109 is a mandatory procedure that must be carried out every 1-2 years, depending on the year of manufacture of the car. Antifreeze renewal may be required earlier than specified if:

In these situations, it is necessary to replace the coolant in the VAZ 2109 system as quickly as possible. Otherwise, the engine may overheat at full speed, which threatens loss of vehicle control and other serious problems for the car owner.

Antifreeze

This is truly a Soviet development, I won’t go into the wilds of history now, but it was created precisely in response to foreign antifreeze. There are two colors (and not one, as many people think) - blue and red.

Blue antifreeze can withstand temperatures up to “-40” degrees Celsius.

Red can withstand up to “-65” degrees Celsius.

They were divided by color specifically to distinguish the temperature threshold.

The composition here is almost the same (only in red the alcohol concentration is slightly higher). Let's list the components:

• Ethylene glycol – dihydric alcohol
• Distilled water
• Additives

The whole secret lies in the additives. Antifreezes use so-called first generation or chemical additives. These are mainly phosphates, borates, silicates, nitrites. The main task is to protect the pipes inside from the corrosive effects of ethylene glycol and distilled water. Changes completely once every 2-3 years.

It should be noted that the composition of antifreeze has not changed for many years, that is, it has been stamped in its “pristine form” for a good 30 to 40 years. There is practically no work being done to identify a new formula.

Replacing antifreeze and choosing it is an important task, but it has nothing to do with the color of the coolant. Some motorists claim that blue or red antifreeze is the most durable and has the best performance. This, of course, is not true; this topic has been discussed hundreds of times on thematic forums and is not worth repeating. Color is just a marketing ploy by antifreeze manufacturers; in addition, thanks to the dye that is added to the coolant, leaks can be detected promptly and effectively. This is where the influence of antifreeze color ends. The color also allows motorists to monitor the condition of the antifreeze; if its color has changed significantly, this is a signal to replace the antifreeze.

Antifreeze replacement process

The procedure for updating antifreeze in a VAZ 2109 is not particularly complicated. For this reason, the vehicle does not have to be sent to a specialized technical workshop - he himself can change the coolant to the system of his car. For these purposes, the car enthusiast will need:

Attention - safety precautions! When working with the VAZ 2109 cooling system and technical coolant, remember that:

To replace the coolant in the VAZ 2109 system, you will need 8.7 liters of fresh coolant. Older “Nines” can hold up to 7.5 liters of technical fluid, but there are models with a capacity of up to 9 liters. Therefore, it is recommended to stock up on 10 liters of fresh antifreeze when changing it in the VAZ 2109 cooling system.

During the process of changing the coolant, problems may arise such as detection of a hidden leak or air entering the system. If a minor leak is detected, you can use sealant for VAZ cars, but in most cases it is recommended to replace the damaged part. When an air lock forms, the engine is run.

The procedure for changing antifreeze on a VAZ 2109 can be divided into 2 stages. Let's talk in more detail about each of them.

Stage one

The first stage is draining the antifreeze from the VAZ 2109 tank , as well as from the cylinder block of the vehicle in question. The step-by-step structure of this procedure is presented below:

Next, it is recommended to flush the cooling system of the VAZ 2109. It is necessary to flush system parts if:

However, system flushing is still recommended early, because during this process, leaks can be easily detected before fresh antifreeze is added. To flush the VAZ 2109 system, you can use both special chemicals and clean distilled water. The liquid is poured into the expansion tank of the VAZ 2109, and the car engine starts for 15 minutes. After this, the spent rinsing substance is drained and the procedure is repeated until the water becomes completely clear.

Stage two

The completion of the procedure for replacing antifreeze on a VAZ 2109 Injector and a standard “Nine” is to fill in fresh coolant. First of all, you need to dilute the coolant concentrate. To do this, you will need a clean container and distilled water. The ratio of liquids depends on the desired boiling point of the antifreeze - the higher it is, the more concentrated the cooling substance should be in relation to water.

Before pouring fresh coolant into the VAZ 2109 system, it is necessary to ensure the tightness of the tank by tightly sealing all drain plugs. The finished mixture is poured into the expansion tank. After this, the engine starts (for 10-15 minutes, the so-called “run”). This is necessary to remove air trapped in the system. After running the engine, be sure to check the level of the coolant; if it has dropped, you need to add the missing amount of antifreeze.
