You will learn how to drain antifreeze from a VAZ-2107 from this article. This manual can be used for any Lada model, regardless of the year of manufacture and drive. But you will have to consider such issues as the service life of antifreeze, how it differs from antifreeze, and during what work it may be necessary to drain the liquid. Both the “kopek” and the “ten” have two drain holes. But the cooling system designs of these cars are different. For example, on a “classic” the liquid is not under pressure, while on “eight” and newer models it is about 1 atm.

Why is it necessary to change antifreeze?

In any modern car The antifreeze circulates in a circle, taking heat from the engine jacket. It is worth noting that there is no need to unscrew the cap of the expansion tank before draining the antifreeze from the VAZ-2107. Injector or carburetor - it doesn’t matter, the circuit is identical. The first "sevens" used water as a liquid. But it has a lot of disadvantages - it freezes at sub-zero temperatures outside, forms scale on the walls and in the pipes, and damages the pump.

Antifreeze is devoid of all these shortcomings, but still has several nuances. The service life is limited - no more than two years, or 90-100 thousand kilometers. Antifreeze is a complex compound that contains a large number of additives. And due to temperature changes, these additives evaporate and lose their properties. The result is that the boiling point increases, the viscosity decreases, and there is a risk of pump breakdowns.

Antifreeze or antifreeze?

Now you’ll figure out how to drain antifreeze from a VAZ-2107. But what to pour into the cooling system if there are two types of liquids on the market - antifreeze ( of blue color) and green). But in fact, you just need to go into the terminology. In fact, antifreeze is antifreeze (literally “against the cold”). But those liquids, which are called antifreeze, are produced according to domestic technology, and “antifreeze” - according to imported ones. In fact, any alcohol can be called antifreeze, since it does not freeze at earthly temperatures. But we cannot fail to note one feature - imported analogues The coolant is of much better quality and has a longer service life. Therefore, it is preferable to use liquids under the trade name “antifreeze”, despite the fact that it is 100-200 rubles more expensive than antifreeze (10 liter canister).

Precautions and Rules

Be sure to follow safety requirements, as draining antifreeze from a VAZ-2107 without this will be risky undertaking. So, the basic requirements:

1. Do not drain liquid in the yard or garage. Antifreeze is toxic; fumes entering the lungs can cause irritation of the mucous membranes and poisoning.
2. You can’t “taste” it - it’s completely deadly. Some “experts” try the liquid to make sure that it is really antifreeze. Such an experiment is very dangerous.
3. If the liquid comes into contact with your eyes or hands, rinse them thoroughly with water. If you suspect poisoning, consult a doctor.
4. Never work on the cooling system if the liquid in it has not cooled down! One careless movement - and some pipe will fly out of its place, and your hands will fall under a stream of boiling water.

Be sure to follow these rules and do not neglect them.

Draining procedure

To work you will need:

1. Container with a capacity of 10 liters or more. Aluminum pans are ideal.
2. 13mm open-end or socket wrench.
3. Pliers.

The last tool may only be needed if the plug on the radiator is stuck and you cannot unscrew it by hand. Before starting work, you need to cover with film all unprotected areas of the electrical wiring that could get liquid to prevent a short circuit.

And now about how to properly drain antifreeze from a VAZ-2107. Place the pan under drainer in the radiator and carefully unscrew the plug. Wait until the liquid has completely poured out. In order not to lose antifreeze, tighten the cap. The next step is draining the cooling jacket. To do this, move the pan under the drain hole in it and unscrew the plug with a 13 mm wrench. Make sure that the front of the car is lower than the back and that the heater valve is fully open. Only in this case will the antifreeze completely leave the cooling system.

Bleeding the system

How to drain antifreeze from a VAZ 2107 block is now extremely clear. But then you need to carry out the reverse procedure - fill it. And this is more difficult, since there is a risk of air jams. To prevent this from happening, you need to adhere to simple rules. Close all drain holes and pour liquid into the radiator neck. Squeeze the pipes to force out as much air as possible. Then close the cap and pour into expansion tank antifreeze Start the engine and warm it up to operating temperature. Please note that in this case it is necessary that the stove tap is open and rear end the car was lower than the front one. As necessary, add antifreeze to the tank and squeeze the pipes with your hands to force out excess air. During the procedure, the nozzle from throttle valve must be disconnected to monitor system filling.

Welcome!
Coolant - by its very nature, it plays a very important role in the cooling system of your engine, because if it is not there, the car will not be able to work for a long time without stopping it. And thanks to the coolant, the car’s engine is constantly cooled, thereby extending the life of your car’s engine.

But over time, the liquid becomes unusable and will need to be replaced. Today we will look at the process of replacing the coolant on cars of the “Classic” family.

Note!
To replace, you will need the following tools: Firstly, you will need to take a “13” wrench with you, and you will also need to stock up on an empty “10” liter container, and it is also recommended to take a clean rag with you!

Summary:

Question?
What kind of coolant do you prefer to fill into your car’s engine, and why? (Write your answer in the comments)

When should you change the coolant?
It must be replaced if:

• When the car travels “60 thousand km” or when it passes 2 years from the date of filling. (Whichever comes first)
• The liquid should also be replaced if it has changed its color to any other. (In most cases it changes its color to reddish)

How to replace coolant on a VAZ 2101-VAZ 2107?

Draining:
1) First, drive the car into the pit.

Note!
The car must be level, or the front must be higher than the rear, but not vice versa!

3) Next, move all the way to the right, the lever that opens the supply of warm air into the car interior; in the VAZ 2106, such a lever is located at the top and in the photo it is indicated by the letter “A”.

5) Then unscrew the radiator filler cap, which is also indicated by an arrow in the photo below.

6) Now remove the drain plug located on the cylinder block.

Note!
After you unscrew the drain plug located on the cylinder block, immediately place a bottle under this hole and drain all the used fluid into it!

7) Then unscrew the radiator drain plug and drain all the waste fluid from the radiator into a bottle.

8) Next, unfasten the belt that secures the expansion tank, and then lift the tank up, as a result of which the remaining coolant will drain out of it and from the hose that is connected to it, which will flow through the radiator drain hole.

Pouring:
1) First, install the radiator tank in place, and also tighten the cylinder block drain plug and the radiator drain plug.

2) Then pour new coolant into the radiator.

3) Next fill new fluid, into the radiator expansion tank.

Note!
Pour new coolant into the expansion tank, a little higher MIN marks by 3-4 cm!

5) Now screw the radiator cap and expansion tank cap into place.

6) Then start the car and let it run for about 4-5 minutes. Idling, after 4-5 minutes of operation, turn off the car and add coolant to the expansion tank and radiator to the required level.

Important!

1. Replace the coolant only when the engine is cold!
2. The liquid is very toxic, so you should only replace it outside or in a well-ventilated area!
3. After about three days have passed after the replacement, check the fluid level and, if possible, bring it to the required level!

Any engine needs proper cooling. And the VAZ 2107 engine is no exception. The cooling in this engine is liquid, it can be either antifreeze or antifreeze. Fluids wear out their service life over time, and the motorist has to change them. Let's figure out how this is done.

Purpose of coolant on VAZ 2107

It’s easy to guess the purpose of the coolant from its name. It serves to remove excess heat from the engine. It's simple: in any engine internal combustion There are many rubbing parts, which during operation can heat up to a temperature of 300°C. If these parts are not cooled in time, the engine will fail (and the pistons and valves will be the first to suffer from overheating). This is where coolant comes to the rescue. It is supplied to a running engine and circulates there through special channels, taking away excess heat.

Once heated, the coolant goes into the central radiator, which is constantly blown by a powerful fan. The liquid cools in the radiator and is then sent back to the cooling channels of the engine. This is how continuous liquid cooling VAZ 2107 engine.

About antifreeze and antifreeze

It should be said right away that dividing coolants into antifreeze and antifreeze is accepted only in Russia. To understand why this happened, you need to answer the question: what is coolant anyway?

Typically, the coolant base is ethylene glycol (in in rare cases- propylene glycol), to which water and a set of special additives, preventing corrosion. U different manufacturers different sets of additives. And all coolants on the market today are classified according to the technologies for producing these additives. There are three technologies:

• traditional. Additives are made from salts of inorganic acids (silicates, nitrites, amines or phosphates);
• carboxylate. Additives in carboxylate fluids are obtained only from organic carbonates;
• hybrid. In this technology, manufacturers add a small percentage of inorganic salts (most often phosphates or silicates) to organic carbonate additives.

Coolant made using traditional technology is called antifreeze, and liquid made using carboxylate technology is called antifreeze.

Let's take a closer look at these liquids.

Antifreeze

Antifreeze has several advantages. Let's list them:

• Of course, antifreeze also has disadvantages. Here they are: small resource. Antifreeze quickly becomes unusable.
• It needs to be changed every 40–60 thousand kilometers;
• effect on aluminum parts. The additives contained in antifreeze negatively affect the aluminum surfaces in the main radiator. In addition, antifreeze can form condensation. These factors significantly reduce the service life of aluminum radiators; Influence at ; The tendency to form condensation can also adversely affect the water pump of the VAZ 2107, leading to premature wear

its impellers.

Now let's look at the pros and cons of antifreeze. Let's start with the pros:

And antifreeze has only one disadvantage: high price. A canister of high-quality antifreeze can cost two or even three times more than a canister of good antifreeze.

Taking into account all the above advantages, the vast majority of VAZ 2107 owners opt for antifreeze, since saving on coolant has never led to anything good.

Almost any antifreeze, both domestic and Western, is suitable for the VAZ 2107. Most often, car owners prefer to use Lukoil G12 RED antifreeze. Others, not so much famous brands

antifreeze are Felix, Aral Extra, Glysantin G48, Zerex G, etc.

Flushing the cooling system Flushing the cooling system is a very important procedure, since the cooling efficiency of the VAZ 2107 engine depends on it. At the same time, many car enthusiasts prefer not to flush the cooling system, but to fill it with new antifreeze

immediately after draining the old one. As a result, the remnants of the old antifreeze are mixed with the new coolant, which has an extremely negative effect on its performance.

That is why it is strongly recommended to flush the engine cooling system before adding new antifreeze. This can be done either with water or with the help of special compounds. Flushing the cooling system with water It should be said right away that this washing option is advisable to use only when there is no good one at hand. flushing fluid. The fact is that ordinary water contains impurities that form scale. And if the driver still decides to flush the cooling system with water, then

best choice

in this situation it will be distilled water.

Water rinsing sequence

Flushing the cooling system with a special compound

The sequence of flushing the cooling system with a special composition is practically no different from the sequence of water flushing mentioned above. The only difference is the operating time of the motor. This time must be clarified (it depends on the composition of the selected flushing fluid and mandatory indicated on the rinsing canister).

Replacing antifreeze on a VAZ 2107

Before starting work, let's decide on the tools and consumables. Here's what we need:

• canister with new antifreeze (6 liters);
• open-end wrenches included;
• a bucket for draining old antifreeze.

Sequence of work

1. The car is installed on an overpass (optionally - on inspection hole). It is better if the front wheels of the car are located slightly higher than the rear ones.
2. On dashboard you need to find the lever that controls the feed warm air to the salon. This lever moves to the far right position.
3. Next, the hood is opened and the expansion tank cap is unscrewed manually.
4. After this, the central radiator cap is manually unscrewed.
5. Use a 16mm spanner to unscrew the drain plug. It is located on the cylinder block. The spent fluid will begin to pour into the container placed (it may take 10 minutes to completely drain the antifreeze from the engine jacket, so you should be patient).
6. Use a 12 wrench to unscrew the plug on the radiator drain hole. Antifreeze from the radiator is drained into a bucket.
7. The expansion tank is held on a special belt. This belt is removed manually. After this, the tank is raised as high as possible in order to drain the remaining antifreeze from the hose connected to the tank.
8. After the antifreeze is completely drained, the tank is installed in place, all drain holes are closed and the cooling system is flushed using one of the above methods.
9. After flushing, new antifreeze is poured into the expansion tank, the car starts and idles for five minutes.
   After this time, the engine is turned off, and a little more antifreeze is added to the expansion tank so that its level is slightly above the MIN mark. At this point, the antifreeze replacement procedure can be considered complete.

Find out more about the cooling radiator design:

A procedure that owners of the same model are periodically forced to deal with is replacing antifreeze on a VAZ 2107. In parentheses, we note that the process is almost identical for the entire family of domestic Zhiguli cars, with the exception of minor nuances associated with design features(for example, the radiator models on the “old” and “new” editions are slightly different). As for the choice of coolant - antifreeze or antifreeze - among experienced motorists there are approximately equal numbers of adherents of both options. In any case, the replacement process is absolutely the same. Replacing antifreeze on a VAZ 2107 includes two main stages: draining the used coolant and filling in new one. In some cases there is a third, intermediate stage. It consists of flushing the system with special chemicals or just water. We strongly do not recommend neglecting this stage - especially if the car has not been subjected to such a procedure for a long time or there is reason to suspect contamination of the system. Naturally, before starting work, purchase the appropriate coolant (in our case, antifreeze). The quantity is determined in accordance with the instructions (the figure is 9.85 liters, i.e. you need to buy 10 liters). We prepare the necessary tools in advance - a screwdriver, a head or a 13-socket wrench, a container for draining the corresponding volume.
First stage

• Let's get to work. First, inside the car, set the heating control knob on the stove to the “maximum” position. This achieves the opening of the tap. We unscrew the plugs on the expansion tank and on filler neck radiator There, on the radiator, we unscrew the plug to drain the coolant (it is necessary to place a prepared container in advance);
• Perhaps there is no such plug on the radiator - it should be located on the left and below. This means that the car has a radiator from an earlier production. To drain the coolant in this case, use the hole in which the fan sensor is located;
• Then it gets out drain plug engine block (a container for waste coolant is also placed there);
• Necessary clarification: under no circumstances should the formation of air lock. To avoid this, it is necessary to disconnect the hose going to the fitting on the inlet manifold. To do this, remove the fixing clamp;
• After making sure that the liquid is completely removed, we put in place all the previously unscrewed plugs;
• We remember the desirability of the intermediate stage (washing), and carry out the necessary manipulations. To do this, simply fill the system with the appropriate composition (or plain water) and drain it as the system fills until the result is obtained.

Filling Carefully pour antifreeze into the hole. A signal that required amount filled, liquid will flow out of the fitting. We put the hose in place, tighten the clamp, and then ensure that the radiator and expansion tank are filled (the recommended level is the central position between the maximum and minimum marks). Having completed the filling process and securely closing all the holes, be sure to start the engine, bringing it to a temperature of 70-90 ° C. We check the fluid level in the expansion tank (you may have to add a little antifreeze). The process described above is quite simple and unpretentious - after one or two times it is performed “automatically”, without additional tips or minute-by-minute checks with instructions. Replacing antifreeze on a VAZ 2107 is quite possible even for those who have a very vague idea of ​​what is under the hood of the car. The main thing is to carry out all manipulations in strict accordance with the recommendations, step by step, alternating actions in the required sequence.

Often people are faced with such a problem as replacing antifreeze on a VAZ 2109. This need may arise as a result of repairing the cooling system, or simply occur according to plan. Approximately every 40,000 km. mileage, this fluid will need to be changed in any case. If the car is used little, then it is worth replacing every two years. Replacing antifreeze on a VAZ 2109 is quite simple. To do this you need to stock up limited quantity tools, as well as a wealth of knowledge, which will be provided in this article. After reading it, you will definitely learn without special problems and carry out this procedure as soon as possible. Tools and materials

• antifreeze It is advisable to take with a small reserve, although five liters is quite enough for the VAZ 2109;
• key to 8;
• hexagon 12;
• screwdriver.

So, all the tools are ready for use, which means you can start.
Instructions The cooling system of a car engine has a rather complex structure. There is not only a tank, but also a number of other equally important components. These are all kinds of tubes and hoses that allow coolant to move freely throughout engine compartment. Moreover, it is worth noting that the system is in a sealed state. To carry out this kind of work, the tightness must be broken. This is done by simply opening the tank cap. Now you can start removing the crankcase protection. Any even unprofessional driver can handle this job. It is necessary to remove the protection so that antifreeze, which is a very toxic liquid, does not get on it. After this, you should turn your attention to the drain plug, which is located on the radiator. It unscrews using a hexagon. Finding it is extremely easy. Every self-respecting car enthusiast knows where it is located. When the plug is removed, it is imperative to bring some kind of container to the hole, into which the already used antifreeze will be removed.
There is also a drain plug on the block head. It must be unscrewed. Here it is also worth placing some kind of container so that the antifreeze does not leak into the street. After all the liquid has been removed from the cooling system, you can screw all the plugs back in. Now you need to turn your attention to the carburetor. There is also a pipe here. It needs to be unscrewed. For this it is used when standard mount a regular screwdriver. Now you can start pouring antifreeze. This must be done extremely carefully so as not to miss the filler hole. In this case, you can use additional devices to make work easier. For example, some car enthusiasts have long preferred to carry out work through a funnel. Liquid is poured in until it begins to drip from the pipe that was unscrewed earlier. This measure will eliminate excess air from the cooling system, which can lead to stagnation of antifreeze, and this has a detrimental effect on the operation of the engine as a whole.
After the liquid has flowed through the pipe, it can be replaced. Then antifreeze is poured into the expansion tank to a certain level. It's best to stick to the maximum cutoff. Now you can warm up the engine. In this case, there is no need to close the hood, because you need to look to see if there are any leaks that could have formed during the work. If smudges are visible anywhere, they must be eliminated immediately. To do this, use a screwdriver to tighten all the clamps securing the pipes and hoses. Are there other mounts? They should be adjusted. So, now everyone knows how to replace antifreeze on a VAZ 2109. As you can see, this process is quite simple. The most important thing is to strictly follow the instructions, then all the work will be done as quickly and efficiently as possible.

The best coolant for VAZ 2110-12

How a car's engine cooling system will work depends on many factors, but its main component is certainly the coolant (antifreeze/antifreeze). The operation of not only the engine and heater, but also the elements of the SOD itself depends on the quality of this fluid. How to choose high-quality antifreeze for VAZ 2110? Why is antifreeze better than water? The advantages of antifreeze/antifreeze are obvious:

1. Low specific expansion when heated
2. Has a high boiling point
3. It has low temperature crystallization (does not freeze, but turns into a gel)
4. Protects the cooling system from corrosion
5. Protects the cooling system from oxidation
6. Has anti-foam properties
7. Has lubricating properties (for example, SOD pump)

Antifreeze or antifreeze? Antifreeze is also antifreeze, which in 99% of cases consists of ethylene glycol. The name "TOSOL" was assigned to one brand of antifreeze back in the USSR, and so it became boring. That is, antifreeze is Russian antifreeze. Antifreeze, unlike antifreeze, can be diluted or a concentrate, which must be diluted before pouring it into the car. How to choose a high-quality coolant? Whether antifreeze is good or not is determined by its quality and set of additives. All properties of antifreeze depend on the set of additives. To avoid buying a fake, antifreeze should be purchased in reliable stores from good and well-known manufacturers. You can choose a brand based on a review of coolants, survey results or comments. What color antifreeze should you buy? Mix coolant different colors Can. More details about this in this article. How long does it take to change the coolant in a VAZ 2110? According to the regulations, it is changed after 5 years or 70 thousand km. mileage, in practice it all depends on the operating conditions and the quality of the antifreeze. How to replace antifreeze in a VAZ 2110? Change the coolant according to these instructions. So, vote and leave reviews about antifreeze for the VAZ 2110-12:

1. What brand of antifreeze/antifreeze did you choose?
2. What do you fill with antifreeze or antifreeze?
3. How often do you change the coolant?

Do-it-yourself 220V engine heating installation

To start the engine in cold weather, you can use various ways that will facilitate this procedure (automobile plant, autonomous heaters etc.). In this article we will consider heating the engine using a heating element from 220V. What are the advantages of such preheating, as well as the disadvantages of this additional equipment further.. Engine preheaters can be autonomous (devices for heating the engine that can work independently) and dependent (devices that cannot warm up the engine without outside help) This article will talk about dependent engine heating, or more precisely about heating the engine from an outlet . Such heaters are usually called heating elements or boilers. Any engine preheating has its pros and cons (even such popular systems as Webasto), so heating of internal combustion engine must be selected individually based on the capabilities and needs of each. The principle of operation of the heating element for heating the engine After connecting the boiler to 220V, the liquid inside the housing (3) is heated; due to the increase in the temperature of the liquid inside the housing, the pressure increases. The valve (4) closes the inlet pipe and, as the temperature rises, the liquid rushes through the outlet pipe. Due to the decrease in pressure inside the body, the valve ( 4) opens, and the liquid begins to flow into it through the inlet pipe. As a result, a directed thermosiphon circulation of liquid is formed through the electric heater and the engine cooling system. With the help of a thermostat (6), the temperature of the liquid is automatically maintained in the SOD and prevents overheating of the electric heater. You can find on the market a large number of boilers from 220V, but which boiler to choose for heating the engine? For heaters from 220V, special heating elements should be used that have special coating and do not have boiling points on their surface, and therefore do not form deposits. Cheap engine heaters use ordinary heating elements from household electric kettles, which are not designed to work in aggressive environments, and especially in antifreeze (antifreeze). They are also not designed to work in constant mode. As a result of using cheap heating elements high temperatures“kill” antifreeze, or rather its additives (anti-corrosion, anti-foaming, etc.). As a result, scale and deposits form, which gradually clog the entire system. Below in the photo are heating elements that have corrosion and deposits - these are ordinary household heating elements. It is recommended to buy boilers for engine heating from proven brands:

• JSC "Leader", Tyumen
• Start-M
• Severs-M

Which power heating element do you need to buy? 0.5 kW - the power of the heating element, which can be used when parked to maintain a constant engine temperature. This power is not enough to warm up the engine in severe frost. 1kW is the power of the heating element, which is recommended to be selected for 8kl VAZ 2110 engines. 1.5kW is the power of the heating element, which is recommended to be selected for 16kl VAZ 2110 engines. How long does it take to warm up the engine to start car in cold weather? The time is selected experimentally and depends on many factors (engine type, electric heater power, air temperature, etc.). Approximately: in order to easily start the engine of a VAZ 2110 16kl in cold weather -30C using a 1.5 kW electric heater, you need to count on a warm-up time of 30-60 minutes. Of course, you can turn on the engine heater for a longer time, then the engine will already be hot, but there will be no boiling.

xn--2111-43da1a8c.xn--p1ai

According to the recommendation of the AvtoVAZ manufacturer, the coolant in the VAZ 2101-2107 engine must be replaced every 2 years or 45,000 km. Of course, many owners of “classics” do not adhere to this rule, but in vain. Over time, the cooling and anti-corrosion properties deteriorate, which can lead to corrosion in the channels of the block and cylinder head.

In order to drain antifreeze or antifreeze on a VAZ 2107, you will need the following tool:

1. Open-end wrench 13 or head
2. Sling on 12
3. Flathead or Phillips screwdriver

So, before starting this work, it is necessary that the engine temperature is minimal, that is, there is no need to warm it up before this.

First of all, we place the car on a flat, flat surface. The heater control damper must be in the “hot” position. It is at this moment that the heater valve is open and the coolant should completely drain from the heater radiator. Open the hood and unscrew the radiator cap:

We also immediately unscrew the cap from the expansion tank so that the coolant drains from the block and radiator faster. Then we place a container of about 5 liters under the drain hole of the cylinder block and unscrew the bolt, as shown in the photo below:

So how to substitute large capacity quite inconvenient, I personally took it plastic bottle 1.5 liters and substituted it:

We also unscrew the radiator cap and wait until all the antifreeze or antifreeze drains from the cooling system:

After that, screw back all the plugs except the filler plug and fill the radiator with new antifreeze to the top edge. After this, you need to fill the coolant into the expansion tank. To avoid the formation of an air lock in the cooling system, you need to disconnect the expansion tank hose, as shown in the picture below:

Now we lift the expansion tank up and pour in a little antifreeze so that it flows through the other end of the hose. And at this time, without changing the position of the tank, we put the hose on the radiator. We continue to hold the tank at the top and fill it with antifreeze to the required level.

We start the engine and wait until the radiator fan comes on. Then we turn off the engine when the fan stops working, and after the engine has completely cooled down, we check the antifreeze level in the conservator again. Top up if necessary!
