How much antifreeze is included. How to pour antifreeze into the engine cooling system? Is it possible to pour water into antifreeze

The main function that the cooling system of an automobile engine sets for itself is the creation of normal working conditions: a temperature index of 110 ° C, a standard value of humidity. Previously, a mechanical method was used to determine this mode: a person applying fingers to the cylinder block should not be subjected to burns after holding for 3-5 seconds.

Water can be used as the simplest coolant for an internal combustion engine (it can be filled in when overheated), but this product has significant drawbacks:

• rots certain metal parts;
• can freeze at sub-zero temperatures.

Therefore, in winter, when the car was idle, this water had to be drained.

Currently, numerous technical fluids, which include antifreeze and antifreeze, are doing an excellent job with this task. Thanks to the original chemical composition, they allow you to make the freezing point low - up to -50 degrees, and also have additives that prevent corrosion.

But the question arises: how many of these tools should be present in the system, how should they be used, and what is the capacity? Consider the answers in the article.

How much fluid is required

Auto users are interested in the amount of antifreeze that must enter the system to maintain its productive operation. So how much liquid do you need? Antifreezes are substances that can remain in a liquid state even at low temperatures, they are used in numerous modern machines, the capacity depends on the parameters. These funds are based on organic substances - alcohols with many atoms. Liquid is poured sequentially. In connection with functional features, they are divided into inorganic, organic and hybrid liquids. So what should be the volume of coolant so that it can ensure the normal operation of the system?

It is worth noting that anything can happen to the cooling system on the road, and fluid drop to a lower level is not uncommon. But now this is not a reason for frustration, because the addition of antifreeze will solve the problem. Of course, you can add a little heated clean water, but it is not recommended to drive on such a mixture for a long time: if possible, it is worth draining the water and adding a full-fledged good antifreeze: how much depends on a number of factors.

Procedure

First you need to choose a good liquid, and you should not save money: give preference to products from well-known brands that have proven themselves from the very best side. Over time, the antifreeze in the cooling system does not increase in volume, since its consistency is not subject to any changes during operation. But there are cases of liquid reduction as part of cooling.

If you want to buy a substance with optimal additives, it is worth using organic products: they will allow your cooling system to work just perfectly. Hybrid elements can contain both organic and inorganic elements; in terms of their properties, they are something in between both options.

Often, the manufacturers themselves indicate a set of elements that are part of the coolant, and this does not allow determining the features under which the product will be operated. For example, in some substances, the use of amines, phosphate compounds should not be observed. If we are talking about hybrid elements, then these substances should also be absent. Consider how much you need to add funds.

How much to pour?

What should be the quantity? It all depends on the brand of the selected product, the type of car. Traditionally, the volume varies from 3 to 6 or more liters: the larger the volume and power of the engine, the more stringent the requirements for the cooling system, otherwise it would not be able to cope with its main task - cooling all elements in the engine. To find out how much to pour into the engine, it is necessary to take into account the manufacturer's recommendations, they are indicated in the machine's instruction manual. Its quantity during the cooling process does not depend on the quality of antifreeze, however, this parameter affects the life of the car and some other indicators.

Antifreeze is one of the main consumables in any car. The coolant is designed to cool the power unit, which helps prevent it from overheating. How Lanos antifreeze is replaced, what liquid to fill in and how to check its level - you will find here.

What type of coolant is filled?

Replacing antifreeze in a Daewoo or Chevrolet Lanos car is an important step in vehicle maintenance. Normal operation of the cooling system is not possible when using low-quality or exhausted Tosola. First, let's consider what kind of refrigerant is used and needs to be filled in the Chevrolet Lanos.

Expansion tank with "Tosol" in Lanos

To know which antifreeze is poured into the system, you need to remember the brand of liquid that you filled in. Initially, the factory uses ethylene glycol based refrigerant during production. Information about this is indicated in the service book for the operation of the vehicle. If you filled in another "Tosol", then you should know which one.

What coolant is better to fill?

Antifreeze replacement in Lanos should be carried out taking into account the requirements of the automobile manufacturer. Therefore, only consumables based on ethylene glycol should be used in the cooling systems of these cars. We will not talk about specific brands of liquid that can be used - there are plenty of them. When buying a refrigerant, be sure to read its composition, it is indicated on the label on the back of the package.

The use of plain water is also not allowed. If you had to fill in water, for example, when all the coolant boiled away for some reason and the engine overheated, then as soon as possible it should be changed to a full-fledged coolant. Especially if it happened in winter. At sub-zero temperatures, water freezes, which can damage the components of the cooling system.

How often should antifreeze be changed?

According to the technical regulations, the replacement of antifreeze in Chevrolet Lanos cars is carried out at least every 40 thousand kilometers. Or once every four years. During this time, the liquid will lose its properties and will not be able to perform the tasks assigned to it.

Spent and new antifreeze for Lanos

How can you tell if a replacement is needed?

Changing and filling the coolant is carried out in such cases:

1. If there is sediment at the bottom of the expansion tank. Looking at the tank, you will see how a dense layer of sediment is located at its bottom. Or all the fluid in the expansion tank may be in the form of a large lump. Often deposits are formed at negative temperatures. Precipitation may appear in the radiator and in the pipes of the cooling system. But it is visible only in the expansion tank. If there is sediment in the cooling system, the replacement of consumables is accompanied by a complete flushing of the radiator, tank and lines.
2. If the freezing point of antifreeze has increased. To check, you can use a special device - a hydrometer. You can find the device at any automotive store. If the properties of the coolant have changed, the consumable must be replaced. The density of antifreeze is checked in accordance with the technical table, which can be found in the service manual for the car. If there is no hydrometer, you can do without it. When the ambient temperature drops to -15 degrees, carefully unscrew the plug on the expansion tank. If there is a yellowish coating on the surface of the liquid, then the consumable has begun to thicken. In the future, this will lead to its rapid freezing. Then the coolant must be replaced.
3. The main symptom is that the consumable loses its natural color. It becomes brown, with a hint of rust. In this case, the refrigerant reacts with the metal components of the radiator device and can lead to their destruction. As a result, the radiator will fail. When the refrigerant becomes colorless, it cannot perform the functions assigned to it. This causes the engine to overheat. Then the coolant needs to be changed.
4. The liquid turned into a cottony state. This can be seen in the summer heat. The appearance of flakes in the liquid indicates the need to replace it.
5. Formation of foam on the surface of antifreeze in the expansion tank. When the refrigerant foams, it indicates the need to replace it. If you ignore the appearance of foam, then the power unit will overheat.
6. Indirect signs include the inefficient operation of the stove. As a result of the fact that the coolant cannot perform its primary functions, the heater works less efficiently. This is especially felt in the winter season.

The brown color of antifreeze indicates its inefficiency.

How to check the level of antifreeze?

Checking the fluid level is carried out according to the marks on the expansion tank:

1. Open the hood of the car, find the expansion tank, it is located on the right if you are facing the car.
2. Take a close look at the container. It has two marks - MIN and MAX. Ideally, the fluid level should be between these two marks. If the level is low, coolant needs to be topped up. Checking the antifreeze level is done on a cold engine.

Coolant volume

Before replacing, you need to know how much fluid to pour into the cooling system. In the case of Lanos, the volume of consumables used is 7 liters, this information is indicated in the operating instructions for the car. As practice and reviews of Lanos car owners show, no more than five liters are required to replace consumables. This is due to the fact that due to the design features of the car, you will not be able to completely drain the entire “Tosol” from it. Some of the liquid will definitely remain in the system, there is no way out of this. Even if you comply with all the requirements and rules for draining consumables from the unit. In addition to antifreeze, you need to purchase about seven liters of water if you plan to flush the cooling system. And in the presence of precipitation in it, washing is required.

You can learn about the consequences of using low-quality antifreeze in the video below (the video was filmed and published by the Jeep Bomba channel).

How to change coolant?

Let us dwell in detail on how to replace antifreeze with your own hands in Lanos.

Required tools

To replace, you will need tools:

• pliers;
• screwdriver;
• wrench 10, it is better to use a socket;
• a bucket or an old basin, the waste liquid will merge into it (a cut-off five-liter bottle will do);
• jack to raise the front of the car;
• a watering can or funnel, with its help you will carefully fill in the new "Tosol" (the cut off top of the bottle will do).

How to drain?

The change of consumable begins with its drain:

1. It will not be possible to completely remove all antifreeze from the system, but you need to try to drain the maximum possible amount of fluid from the engine. To do this, the vehicle must be installed on a flat surface, it will be more convenient to drive it into a pit or overpass.
2. Find the refrigerant drain plug on the radiator device, it is located on the left, in the lower corner, as shown in the photo. Place a prepared container under the plug to collect the used antifreeze. Open the lid.
3. After that, unscrew the filler cap located on the expansion tank.
4. The draining process will start. To quickly drain the consumable from the system, you need to dismantle the pipe from the fitting located on the throttle. This branch pipe is removed from the throttle assembly with pliers or a screwdriver.
5. You cannot drain all the coolant, but you can try to minimize its remaining in the cooling system of the power unit. To do this, take a jack and use it to lift the rear right wheel.

1. A leak can be confused with a decrease in the volume of consumables, this always happens in winter. In the cold season, at negative temperatures in the expansion tank, the refrigerant loses volume a little.
2. The appearance of cracks and other damage to the tank. Finding these defects, especially if they are minor, is not so easy. Sometimes they are not visible and look like scratches. Minor damage can be repaired by cold welding. If the cracks are serious, then the expansion tank must be replaced.
3. The connections of the pipes of the cooling system are depressurized. This is often associated with loose clamps. These elements must be tightened or replaced.
4. Damage to hoses and pipes. They wear out as a result of long-term operation or mixing different types of antifreeze. The simultaneous use of coolants of different composition can lead to a chemical reaction that aggressively affects the rubber elements of the system - pipes and hoses. Damaged lines must be replaced.
5. Worn thermostat gasket. Usually, when the gasket is worn, the thermostat itself also changes, since the service life of these elements is the same. It is advisable to change the thermostat.
6. Malfunctions in the operation of the radiator device. If the radiator is leaking, you can try to repair it with cold or argon welding. But this rarely helps, usually the radiators just change.
7. The leak may be due to antifreeze getting into the engine oil. This problem is the most serious, it occurs as a result of damage to the cylinder head gasket or the cylinder head itself. You will have to remove the head and carry out a detailed diagnosis of the unit. A damaged gasket must be replaced.

How to spot a leak:

• while driving, smoke went out from under the hood of Lanos;
• after starting the engine, white steam comes out of the exhaust pipe of the car;
• the stove does not work well, does not heat, but only cools;
• an engine malfunction indicator appeared on the dashboard;
• the arrow of the temperature sensor has risen to the maximum;
• in the car interior it smells of antifreeze due to a leak in the stove radiator;
• There is a puddle under the front seat mat.

It is not so rare that a happy owner of a car drives his vehicle without even looking under the hood. Such operation is not permitted. For example, all the antifreeze can leak out of the combustion system, and then the engine will definitely have to be overhauled. Therefore, it is necessary to monitor the presence of coolant (coolant) and know which one is filled into the system.

COOLING SYSTEM VAZ 2114

Once, back in Soviet times, water was poured into the radiator of a car as a coolant. But it was very inconvenient - in cold weather it had to be drained regularly so as not to defrost the system, and in the morning before the trip it was necessary to run with buckets of hot water. In addition, the cooling jacket in the cylinder block and in the block head suffered from corrosion. Nowadays, water is practically not used anymore, antifreeze or antifreeze is poured into the cooling system (CO).

The volume in CO is about 8 liters (7.8 liters according to factory conditions). Any coolant can be filled in a car that came off the assembly line; the manufacturer does not follow any specific rules in this matter.

But if the liquid leaves or the time has come for its replacement, then topping up or replacement is necessary. And here you need to know what is poured into the system, and whether it is possible to mix antifreeze with antifreeze.

ANTIFREEZE

The name "antifreeze" contains Greek and English roots. The Greek "anti" means "against", the English "friez" is translated as "freeze". Therefore, the coolant, the cooling system, should not only prevent the internal combustion engine from overheating, but also not freeze in frosty weather. The basis of antifreeze is ethylene glycol, and the freezing point of the coolant depends on how much water is added to the chemical composition. Fluid components do not lead to corrosion of engine parts.

The color of the composition can be almost any color, ethylene glycol itself is colorless. They color the composition in order to see it in case of leakage, and to drink it, the antifreeze itself is poisonous. In addition, the old coolant changes color, which means that it is time to replace it.

TOSOL

Antifreeze is a kind of antifreeze, only at one time it was specially developed for VAZ cars. It has a blue color, and can be concentrated, diluted by 60% with water (grade A-40M), diluted by 35% (A-65M). In its pure form, the concentrate is not used, it is diluted at its discretion, depending on the freezing temperature, which is oriented in the region where the car is located. Antifreeze has a more aggressive environment, but this does not mean at all that it is of poor quality.

MYTHS ABOUT ANTIFREEZE AND ANTIFREEZE

• Antifreeze is worse than antifreeze. This is not true. Both coolants are made on the same base (ethylene glycol). But their density is different, and they are used to measure this parameter.
• The color of the liquid is an indicator of quality, and its composition depends on the color. In fact, the composition is basically the same for all coolants, and does not depend on the color. Antifreeze is mainly tinted with green and red.

FILLING LIQUID INTO THE SYSTEM

What kind of coolant to fill in always worries the car owners of these cars. There is no big difference, you can pour antifreeze into the cooling system, you can also antifreeze, but mixing the compositions is still very undesirable. Antifreeze has a more aggressive environment due to other additives, and its too concentrated composition can even “corrode” the radiator over time. Top up with the brand of coolant that was previously filled in the system. If the brand is not known, then it is better to make a complete fluid change.

REPLACEMENT WITH FLUSHING

Is it possible to replace antifreeze with antifreeze? Why not. It is only necessary to flush the cooling system when replacing antifreeze with antifreeze. Conversely, you need to flush the cooling system when replacing antifreeze with antifreeze. already indicated - the compositions are different and mixing can lead to foaming of the coolant. Of course, an explosion will not occur, but long-term use of a mixed composition is not recommended. Rinse the system with clean water, and the water is changed several times. Rinse until a clear liquid drains from the radiator, without dirty impurities.

Replacing the coolant with a VAZ is done by hand in stages:

1. We put the car evenly, at an angle all the coolant may not merge;
2. expansion tank;
3. Loosen the drain plug at the bottom of the radiator. We prepare the container where the contents from the radiator are drained in advance;
4. We twist the plug on the cylinder block, drain the coolant from the block. To get to the plug, it is necessary to dismantle the ignition module. The module is mounted on three bolts;
5. We wrap the plugs, fill in the water and start the engine. Let the engine run for fifteen minutes;
6. As already written above, we flush the system several times;
7. Then fill in new fluid and drive the air plug. How many liters of antifreeze are provided in the VAZ 2114, so much should be included in the system.

REMOVING THE AIR PLOCK

How to fill in antifreeze when an air lock occurs? There are different ways to fill the liquid (we will consider below).

Air removal through the throttle assembly:

1. Remove one of the coolant supply hoses on.
2. Remove the expansion tank cap and cover the tank with a clean rag.
3. We blow through a rag into the tank until coolant flows from the removed hose.
4. We quickly put the hose in place, tighten it with a clamp, add liquid to the level. How much antifreeze will still be included in the VAZ 2114 depends on how “airy” the system is.

Bleeding air through the throttle without removing the plug of the expansion tank:

1. We warm up the engine and turn it off.
2. Remove one of the throttle hoses.
3. After a short time, the air should come out and antifreeze flow.
4. We also quickly put on the hose.
5. Check coolant level and top up if necessary.

Bleeding by tilting the vehicle:

1. We're going up the hill.
2. We remove the tank cap.
3. We warm up the engine to operating temperature.
4. We gas hard. If the liquid falls into the system, add it.

You can independently change the cooling radiator to a VAZ. In this case, an air lock may also form. It is necessary to control how many liters of antifreeze will enter the VAZ 2114. If there is a lot of new coolant left in the canister, the plug must be removed, otherwise the engine may overheat.

It should be remembered that the volume of the cooling system in the VAZ 2114 is approximately 7.5-8 liters.

If you don’t want to bother with replacing the coolant, you can drive the car to a car service. The cost of such work depends on the region and the degree of equipment of the car workshop or center. On average, the price ranges from 300 to 600 rubles.

• Hot liquid must be drained carefully, gloves and tight waterproof clothing must be used.
• After replacement, you need to check if there is an air lock in the system. Air must be expelled, otherwise the engine may overheat.
• When draining the liquid, use a plastic bag or a rag to prevent coolant from getting into it.
• When mixing antifreeze with antifreeze, nothing particularly terrible will happen, but mixing is still desirable to avoid.

Take care of your car!

Antifreeze is a special liquid designed for the car's cooling system. The peculiarity of this substance is that it does not freeze even at low temperatures. And this effect is possible due to the special composition of the liquid - ethylene glycol and water, which together form a dihydric alcohol. Antifreeze also contains so-called inhibitors - substances that slow down the corrosion process.

For the smooth operation of the car, it is extremely important to replace the antifreeze in a timely manner. we have already told you from the car, but we will describe in detail how to fill the cooling system with new antifreeze in this article.

Terms for replacing antifreeze

The exact service life of the consumable cannot be called just like that - it all depends on the manufacturer of the refrigerant, the composition of the coolant and the additives added to it. Today, in the domestic market, you can find coolants made on the basis of silicate or carboxylate.

For example, foreign-made coolants that contain silicate must be replaced at least every 3 years, or once every 100-150 thousand km. run. Carboxylate-based antifreezes, under ideal conditions for the operation of the engine and cooling system, can work for at least five years or 250 thousand kilometers.

How to pour antifreeze into the cooling system?

New antifreeze is recommended to be poured only into a clean cooling system. However, before that, it is important to understand what exactly you are going to fill in. After all, there is no such confusing classification as that of coolants anywhere else.

To avoid the formation of air jams in the system, we put the car in a strictly horizontal position.

1) . We disconnect the uppermost pipe that supplies antifreeze to the engine (as a rule, it is located in the intake manifold area).

2) . Pour new antifreeze through the neck of the expansion tank, which is most conveniently done using a funnel.

3) . We fill it until it starts to flow out of the disconnected pipe, after which we put the pipe in place and clamp it at the junction with a clamp.

4) . The optimal level to fill is between the "MIN" and "MAX" marks.

5) . After pouring, close the tank cap tightly, start the car and warm it up until the fan turns on.

7) . Top up if necessary. Once again I want to note that the last point is performed only with a cold engine.

How much antifreeze should be added?

The amount of antifreeze that needs to be poured into the car's cooling system is usually indicated in the instruction manual for a particular model. But on average, this figure is 6-8 liters.

You can navigate using the "MIN" and "MAX" marks on the expansion tank. That is, as noted above, the liquid level in the tank must be between these marks.

How to add antifreeze to the cooling system?

You should find out the brand, type of liquid and supplement the contents to the required level with an identical composition. Work should only be carried out with a cold engine.

We first slightly open the cap of the expansion tank, which will eliminate excess pressure, after which we completely unscrew the cap and add antifreeze (we focus on the “MIN” and “MAX” marks).

It is not necessary to add antifreeze to the eyeballs, which is fraught with splashing out excess and getting them on the working parts of the power unit in a warm state.

What kind of antifreeze can be filled in?

What are they like? According to their composition, they are divided into:

• silicate;
• Carboxylate;
• Hybrid.

Each type has its own characteristics and characteristics.

Silicate. They contain salts of inorganic acids - the main additives of this type of coolant. A negative characteristic of such a liquid is the formation of plaque. Salts form a thin film of plaque over time. It settles and does not allow the system to fully work, which can lead to heating of the car engine. Consequently, and to a greater consumption of oil and fuel.

Carboxylate. Contains organic acids. This type of antifreeze has the following designations: G12 or G12 +. Organic acids, unlike inorganic acids, do not form scale and plaque. They differ in anti-corrosion and anti-cavitation properties.

hybrid. Contains both organic and inorganic acids. This type has the following designation: G11. Combines the positive and negative properties of the two previous types.

A novelty among coolants is lobrid antifreeze - G12 ++ and G13 containing organic bases and mineral additives. Due to the unique composition, this substance can last up to 100,000 km.

The most common and popular option, although not of very high quality, is “Traditional Antifreeze”. Its service life is not more than 2 years. This type cannot withstand high temperatures. It starts to boil at 105 degrees Celsius. Of the "Traditional Antifreezes" antifreeze is the most famous.

Selection rules . When choosing a coolant, one should be guided by the qualitative features of each type. The presence of various additives significantly affects the quality and service life of the fluid. The quality and service life are also affected by the presence of various additives.

The lowest percentage of additives in G11 coolants, which affects product quality. It is not able to protect against scale and corrosion. The service life of this type of substance is not more than 2 years. In the case of large runs, it can be reduced to 6 months.

Antifreeze coolants such as G12 have a longer service life. As a rule, they have it from 4 to 5 years.

Carbon coolants without replacement can last at least 5 years.

Features and Warnings . Sometimes it becomes necessary to top up the coolant. To do this, you should purchase a new antifreeze of exactly the same type that is already poured into the car. Avoid mixing different types of liquids, even if they are the same color. It is highly forbidden to mix G12 and G11 antifreezes. They are incompatible.

G12+ fluids are miscible with two other types.

Is it possible to pour water into antifreeze?

If you convey the essence of the manufacturer's recommendations, then it is strictly forbidden to add water to antifreeze. This ban is justified by the fact that the coolant is enriched with appropriate additives that have a beneficial effect on the cooling system. They contribute to excellent lubrication and accelerated cooling of the engine.

How to find out what is flooded, antifreeze or antifreeze?

As a rule, motorists know what is poured into their cooling systems. But this is the case if we are talking about a permanent owner of a car. In fact, there can be a lot of reasons why a motorist wants to know what exactly is poured into the expansion tank of his car.

How to determine what is filled? There is a myth that antifreeze tastes sweet, but this is nothing more than just a myth. Yes, and you need to be careful when "tasting" - the chemicals that make up the coolant are extremely toxic.

What should a motorist do if he wants to know what kind of refrigerant is poured into the cooling system of his car?

• Feel and smell. Traditional antifreeze is odorless and feels oily to the touch. Russian "Tosol" to the touch will not be as oily.
• For resistance to frost. If you pour a small amount of coolant into a bottle and place it in the freezer, then it should not freeze. If it is frozen, then most likely it is "Tosol" of poor quality production, if not, then this, in all likelihood, is high quality antifreeze.
• Consumable compatibility with tap water. Take some coolant from your car's system and pour it into a bottle. In a one-to-one ratio, pour ordinary tap water into this bottle, wait about an hour. If you see a layering of substances, the mixture becomes cloudy or there is a precipitate, then this is Russian-made Tosol. When using high-quality foreign antifreeze, this should not occur.
• You can find out which refrigerant is filled in by density. But for this you will need a hydrometer - a special device for checking the density of the coolant. The test of the substance is carried out at an ambient or room temperature of more than 20 degrees Celsius. If the density of a substance is from 1.073 to 1.079 g / cm3, then you most likely have a good antifreeze.

This article is published primarily at the request of a visitor to our site named Vladimir, who recently became the proud owner of a car brand VAZ-2107.And he, of course, immediately had questions related to repair and maintenance of your car, the answers to which he decided to find on the Internet (in particular on this site). Well, help a person who wants competently spend do-it-yourself car repair, holy work! The question was - How to replace the coolant in a VAZ-2107 car? You can find the answer to it by clicking on the link - read in full. ... I think that this article will be useful to owners of other cars of the brand VAZ. Since the process replacement of antifreeze or antifreeze in a VAZ 2107 car almost no different from the process coolant replacement in other cars of the brand VAZ of the Zhiguli family (such as VAZ-2101, VAZ-2104, VAZ-2105, VAZ-2106).

First, let's define the quantity and type coolant, which we will fill in the car. As for the quantity, everything is simple here - according to the instructions, 9.85 liters are needed, which means we buy 10 liters of coolant. But with a view coolant make up your mind, it won't be quick. What to fill? Tosol or antifreeze? There is no consensus. As for me, I can advise to use antifreeze. You can buy it ready for use or a concentrate and dilute it with distilled water in a ratio of 50 to 50. I won’t explain why antifreeze, if you wish, on the site you can familiarize yourself with the material that describes. Yes, and using a Google search, you can find a lot of useful information on this topic.

As for the tool. ... There will be enough box wrench for "13", a screwdriver and a container to drain the old coolant(perhaps, the open-end wrench on “30” will still come in handy).

The procedure for replacing coolant in VAZ-2101, VAZ-2102, VAZ-2103, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107, Zhiguli cars:

Before you start draining the old coolant, it is necessary in the passenger compartment, put the heating tap control lever in the extreme right position (the tap is open). We unscrew the plug of the expansion tank and the plug of the filler neck of the radiator. In the lower corner of the radiator we find the drain plug (photo 2), unscrew it and drain the liquid into a previously prepared container. On old-style radiators, there is no such plug. Instead, with the key to “30”, you will have to unscrew the fan switch-on sensor (photo 3). Also on the engine block, we find and unscrew the drain plug with the key to “13” (photo 1).

After the liquid is drained, we twist the drain plugs into place. And in order to avoid the formation of an air lock in the system, we dissolve the clamp with a screwdriver, and remove the rubber hose from the intake manifold fitting (photo 4).

Everything can be poured antifreeze. As soon as liquid begins to flow from the fitting, you can put a hose on it and tighten the clamp. After, completely fill the radiator and tighten the plug. Next, pour antifreeze into the expansion tank (photo 5), the optimal level is 3-4 cm above the “MIN” mark.

We start the engine and warm it up to operating temperature. After that, turn off and check the level again coolant. Top up if necessary antifreeze.

If the car cooling system is dirty, it should be washed with water or special means. The procedure for flushing is the same as when changing the fluid - drain, fill and dilute, start the engine for a few minutes and drain. And so several times, until you see that clean water flows from the radiator and engine block.
