How much antifreeze is poured into a vaz 2107. What is better antifreeze or antifreeze for vaz

Replacing antifreeze in the engine cooling system is an event that is performed at regular intervals in order to maintain the efficient operation of the cooling system. Today you will learn how to drain and change antifreeze for a VAZ 2107 and why this is done.

Why change antifreeze?

The cooling system of many modern cars is liquid. That is, heat transfer is carried out by a liquid that circulates through a system of pipes and, being cooled in a radiator, returns back to the engine to receive a new portion of heat. In the engine cooling system of the VAZ 2107, water was initially used, later, due to its reduced resistance to negative temperatures, it was.

Antifreeze, in comparison with water, has good resistance to frost and does not freeze at all. In addition, it is not a source of scale, which means it does not clog the cooling system.

In the process of constant temperature exposure, antifreeze may lose its properties. That is, first of all, its boiling point decreases and becomes equal to the boiling point of ordinary water. Secondly, such a liquid can easily freeze and cause a cracked tank, and in the worst case, a cracked cylinder block. That is why antifreeze must be changed at least once every six months during seasonal car maintenance in order to avoid undesirable consequences.

How to drain antifreeze?

In order to drain the antifreeze, it is not enough just to turn off the taps. To begin with, it is necessary to learn that antifreeze is a toxic substance, which means that it can be dangerous to humans if not handled properly. In this regard, there are a number of rules that must be observed without fail:

In order to properly drain the antifreeze, it is necessary to prepare an empty container with a capacity of at least 10 liters. The most desirable condition is the presence of a wide cavity and a shallow bottom. The fact is that there is not enough space under the car in height, but it is enough in width. That is why many drivers use the most ordinary aluminum trough for these purposes.

Once you have everything you need ready, park the car on a level surface, and best of all, place a trough under the radiator. Open the hood and unscrew the cap from the expansion tank. This is to make it easier for the liquid to come out. After that, unscrew the faucet located on the radiator.

If you have an old-style copper radiator installed, then this tap acts as a fan switch-on sensor and is designed for a 30 wrench. To remove it, you first need to disconnect the contact wires from it, and then unscrew it. Now it remains to wait until all the coolant is completely out of the radiator. To speed up this procedure, you can shake the front of the car.

The last tank is filled to a level that corresponds to the norm. After all the procedures, screw the lid on it.

Check the operation of the cooling system - start the engine and warm up to operating temperature. If the cooling fan kicks in and the temperature drops, the system is fully operational.

That's all. This is how easy it is to replace antifreeze on a VAZ 2107 car. As you noticed, this procedure does not require special knowledge and skills, as well as the availability of specialized equipment. It is enough to have only a standard automotive tool kit and a garage.

Replacement of antifreeze, in domestic VAZ 2107 cars, is carried out with a standard frequency - once every 2 years or after 60,000 km. It all depends on which of the conditions will be met first. In addition, the fluid must be replaced if it has changed color, for example, it has acquired a reddish tint.

Which antifreeze is better, and how much to fill it with?

Before draining antifreeze, you must decide on the brand of new coolant and purchase it in the required amount. VAZ 2107 cars require 9.85 liters to fully fill the cooling system. This means that one 10-liter container of antifreeze will be enough. When buying a coolant, please note that some antifreezes are sold in the form of concentrates and require dilution with distillate, in a ratio of 1 to 1.

To replace antifreeze, you can use the following types:

• For the "sevens" from 1998 to 2002, the best option for the G12 coolant is red. This should include MOTUL Ultra, Lukoil Ultra, Castrol SF and others.
• In the VAZ 2107, manufactured from 2003 to 2012 and beyond, it is recommended to use G12 + or G12 ++ antifreeze of the following brands - MOTUL Ultra, Castrol Radicool Si, Zerex G.

Replacement process

Before draining antifreeze, stock up on the necessary tools. You will need a minimum set, which includes a “thirteen” key, a group of screwdrivers, a container (the old coolant will merge into it), as well as 10 liters of a new composition in a canister.

Drain antifreeze

Replacing antifreeze begins with draining the old working fluid. First, find a flat surface to perform all the manipulations. It is better to work on a flyover or a pit, in a garage. If it is not possible to level the machine, it is allowed to raise the front part a little higher than the rear (the opposite situation is excluded).

1. Remove, if present, the engine protection. To do this, it is enough to unscrew the twelve fixing bolts. Also remember that there are four plastic fasteners.
2. Go to the salon and move to the right side the lever, which is responsible for the exit of warm air, from the heating system in the car. As a rule, it is on top.
3. Open expansion tank. Assess the condition of its plug and, if there are defects, replace it.
4. Open the filler neck at the top of the car's radiator.
5. Unscrew the plug that closes the coolant outlet from the engine block. Before draining the antifreeze, substitute an empty container (bucket or bottle) to remove the old coolant.
6. Transfer the container or substitute a new container under the radiator, then open its drain. Wait until the old coolant is completely out of the system.
7. Discard the belt that holds the expansion tank. Now lift the tank up to drain the antifreeze from the connected tube. The remaining coolant, in this case, exits through the drain in the radiator.
8. Leave the car for a while to make sure that the coolant is completely out

Pouring new antifreeze

Now move on to replacing the antifreeze. To do this, proceed as follows:

• Return the tank of the cooling system to its original place and screw the plug onto the drain hole of the VAZ 2107 cylinder block. Do the same with the drain plug on the radiator - screw it into place.
• Pour new antifreeze into the radiator, then do the same work for the expansion tank. Follow the position of the coolant in the system, according to the control marks. Stop pouring antifreeze when its line is 3-4 cm higher than the MIN dash.

Removing air from the system

Now remove the air locks from the system. To do this, find the outlet, bypass and inlet pipes of the radiator, after which, press them several times with your hands.

You can do it differently. Put the car so that the front end is higher, start the engine and let it run for 5-6 minutes at idle. Now return the radiator and reservoir caps to their original places. After starting the engine for the first time, check the coolant level in the reservoir again. If it's low, top up.

Finally, consider the following points:

• Antifreeze should only be replaced when the engine is cold.
• Remember the toxicity of the coolant, so work should be done only on the street. It is allowed to perform all manipulations indoors, but with good ventilation.
• After three days, from the moment of replacement, check the level of antifreeze again. If necessary, bring it up to standard.

Now you know the nuances of how to drain antifreeze in domestic VAZ 2107 cars, which coolant to give preference to when choosing, and also what you need to consider when filling in a new composition and removing a plug. Such knowledge allows you to do the work yourself, saving on the services of service stations.

You will learn how to drain antifreeze from a VAZ-2107 from this article. You can use this manual 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 for what work it may be necessary to drain the liquid. Both the penny and the ten have two drain holes. But the schemes of the cooling systems of these cars are different. For example, on the "classic" the liquid is not under pressure, while on the "eights" and newer models it is about 1 atm.

Why is it necessary to change antifreeze

In any modern car, 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. In the first "sevens" water was used as a liquid. But it has a lot of shortcomings - it freezes at a negative temperature outside, forms scale on the walls and in the nozzles, and disables the pump.

Antifreeze is devoid of all these shortcomings, but still there are several nuances. The service life is limited - no more than two years, or 90-100 thousand kilometers. Antifreeze is a complex compound, which includes a large number of additives. And because of the temperature difference, these additives evaporate, lose their properties. The result - the boiling point rises, the viscosity decreases, there is a risk of pump breakdowns.

Antifreeze or antifreeze?

With how to drain the antifreeze from the VAZ-2107, now you will figure it out. But what to fill in the cooling system if there are two types of liquids on the market - antifreeze (blue) and green). But in fact, you just need to go into the terminology. In fact, antifreeze is antifreeze (literally "against the cold"). Here are just those liquids that 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 terrestrial temperatures. But it is impossible not to note one feature - imported analogues of coolant are much better, they have a longer resource. 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 the safety requirements, since draining the antifreeze from the VAZ-2107 without this will be a risky undertaking. So the basic requirements are:

1. Do not drain liquid in the yard or garage. Antifreeze is toxic, evaporation, getting into the lungs, can cause irritation of the mucous membranes, poisoning.
2. You can not taste "taste" - it is completely deadly. Some "experts" try the liquid to make sure it's really antifreeze. Such an experiment is very dangerous.
3. If the liquid gets into the eyes, hands, rinse them thoroughly with water. If poisoning is suspected, consult a doctor.
4. Never work on the cooling system if the liquid in it has not cooled down! One careless movement - and some branch pipe flies out of its place, and hands fall under a stream of boiling water.

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

Fluid drain procedure

For work you will need:

1. Capacity of 10 liters or more. Aluminum pans are ideal.
2. The key is 13 open-end or socket.
3. Pliers.

The last tool may be required only if the plug on the radiator is stuck and it is impossible to unscrew it with your hands. Before starting work, it is necessary to cover with a film all unprotected sections of the electrical wiring that can get liquid, to prevent a short circuit.

And now about how to properly drain the antifreeze from the VAZ-2107. Place the pan under the drain hole in the radiator and carefully unscrew the plug. Wait until the liquid is completely poured out. In order not to lose antifreeze, twist the plug. 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 key. Pay attention to the fact that the front of the machine is lower than the rear, and the heater valve is fully open. Only in this case, the antifreeze will completely leave the cooling system.

Bleeding the system

How to drain the antifreeze from the VAZ 2107 block is now extremely clear. But after that you need to carry out the reverse procedure - fill it. And this is more difficult, since there is a risk of air congestion. To prevent this from happening, you need to follow simple rules. Close all drain holes and pour fluid into the radiator neck. Squeeze the pipes to expel the air as much as possible. Then close the cork and pour antifreeze into the expansion tank. 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 the rear of the machine is lower than the front. As necessary, add antifreeze to the tank, squeeze the nozzles with your hands to force out excess air. During the procedure, the nozzle from the throttle must be disconnected in order to control the filling of the system.

In this article, we will consider how to change the coolant on VAZ-2101 - VAZ-2107 cars with our own hands, that is, on the "classic". The process is similar for many models of the Zhiguli family, for example, replacing antifreeze with a VAZ 2111, but still there are some nuances.

First of all, you need to determine what kind of coolant you will fill in your car - antifreeze or antifreeze. It is widely believed that for domestically produced cars, especially for classics, only antifreeze should be used. But antifreeze is also suitable, it has many advantages. You can take a ready-made solution, you can prepare it yourself. To do this, take the concentrate and dilute it with distilled water in equal proportions. Therefore, it is up to you to decide what to fill in the Zhiguli cooling system, in any case, there is plenty of information on this topic.

What tools will be needed? A screwdriver, a ring wrench for "30" and "13", a container into which we will drain the used antifreeze.

As for safety, work on a cold engine, otherwise high-pressure fluid can escape and burn the skin. Do not allow liquid to come into contact with skin and mucous membranes.

Do-it-yourself coolant replacement for a VAZ

• The heating valve in the cabin must be fully opened, that is, transferred to the extreme right position. Now unscrew the plugs on the expansion tank and on the filler neck.
• We find a drain plug on the radiator. It is located in the lower left corner. Substitute a pre-prepared container and unscrew the cork. If your car has an old-style engine, then you will find a drain plug on the radiator. Instead, you need to unscrew the fan switch on sensor (use the box wrench on "30"). Drain the used liquid.
• Now find the plug on the engine and unscrew it with a spanner wrench to "13". We also drain the liquid into a container.
• After all the antifreeze has drained, tightly wrap the plugs of all drain holes. You can start pouring new antifreeze.
• How to avoid the appearance of air jams in the system, or at least significantly reduce them? To do this, unscrew the clamp with a screwdriver and remove the hose from the intake manifold fitting. Now carefully pour the coolant into the expansion tank until it starts to pour out of the fitting. At this point, you need to return the hose to its place and tighten it with a clamp. Clamp, by the way, it is better to buy a new one. Now completely fill the radiator with antifreeze and tighten the plug. The level to which you will fill in the liquid is approximately 4 cm above the minimum mark.
• Now let the engine run to rid the system of excess air. It's about 10-15 minutes. Again, we wait until the engine cools down (or you can put a thick cloth on the lid and open it slightly), check the level of antifreeze. As a rule, it has become lower, and the liquid needs to be added.

Coolant plays an important role in the engine cooling system. Without it, the engine will not be able to work for a long time. Thanks to antifreeze, the life of the engine is extended due to the fact that it is constantly cooled.

Why then is it necessary to change the antifreeze for the VAZ 2107? With use, the coolant loses its original properties and is not able to cool the engine. Timely fluid replacement is a process that is easy to perform at home if you know the step-by-step replacement procedure, which will be discussed in the article.

Terms of coolant replacement in VAZ 2107

The purpose of the coolant in the VAZ 2107 is to remove excess heat from the car engine. Indeed, in the process of operation, many parts of the internal combustion engine reach a temperature of 300 degrees C. If the engine is not cooled in time and sufficiently, it will fail. The coolant solves this problem, it is supplied to the running engine, flows through the channels, thus taking away excess heat from the internal combustion engine.

After heating, the coolant goes to the central radiator, which is constantly blown by the fan. After cooling in this unit, the liquid enters the engine cooling channels again. This is the procedure for continuous liquid cooling of the VAZ 2107 engine.

The general principle of operation of the VAZ 2107 cooling system can be studied according to the diagram below.

How to understand what kind of coolant is required for the VAZ 2107 - antifreeze or antifreeze? Since we are talking about a Russian car, it is necessary to distinguish between such concepts as antifreeze and antifreeze to clarify concepts.

It should be noted that such a division and distinction is accepted only in the Russian Federation. To answer this question, you must first understand: what is the coolant?

So, the basis of the coolant is ethylene glycol, less often propylene glycol. Special additives are added to it, which are corrosion protection. Each manufacturer adds different types of additives.

We distinguish between coolants on the modern market according to additive production technologies:

• traditional, in which additives are made from salts of inorganic acids: silicates, nitrites, amines, phosphates;
• carboxylate, additives are made from organic carbonates;
• hybrid, consists of a mixture of organic carbonate additives and inorganic salts (in a smaller amount, including phosphates or silicates).

So, the main difference between antifreeze and antifreeze is that coolant made using traditional technology is called antifreeze, and made using carboxylate technology is called antifreeze.

Advantages and disadvantages of using antifreeze

Pros:

Disadvantages of antifreeze:

• replacement frequency. Antifreeze has a small resource, becoming unusable after 50 thousand kilometers;
• negative impact on aluminum parts. The additives used to create antifreeze adversely affect the aluminum surfaces in the main radiator (which significantly reduces its service life);
• due to the tendency to form condensation, negatively affects the water pump VAZ 2107, as a result - premature wear of its impeller.

Consider the advantages and disadvantages of using antifreeze

Pros:

The lack of antifreeze is obvious —its high cost. At a price, it exceeds antifreeze by an average of 3 times.

Antifreeze Replacement Instructions

Antifreeze, in comparison with water, is quite resistant to frost - it does not freeze. Also, it is not a source of scale, which means it does not clog the cooling system.

But, subjected to constant temperature influences and fluctuations, antifreeze loses its properties during operation:

• boiling point goes down, respectively, becomes equal to the boiling point of water;
• liquid can freeze, as a result - a cracked reservoir or a cracked cylinder block.

For these reasons, it is necessary to change antifreeze at least once every six months. It is important to do this during seasonal car maintenance. Timely replacement of the coolant will help to avoid unpleasant consequences, unwanted repairs and unnecessary waste of money.

So, replacing antifreeze with a VAZ 2107 includes drain antifreeze, flushing the cooling system(if necessary) and replacement used coolant on new antifreeze or antifreeze.

Prepare the following in advance materials and tools:

• canister with new antifreeze (6 liters);
• funnel;
• wrench “13”;
• open-end wrench “16”;
• key “for 12”;
• an empty container of 6-10 liters (often a cut canister is used);
• a clean rag made from natural fabrics;
• protect your hands with gloves.

Drain

Draining antifreeze from the VAZ 2107 tank includes the following sequencing:

flushing

Flushing the cooling system is an important procedure. It depends on it how efficiently the VAZ 2107 engine will be cooled. A number of car owners believe that flushing the cooling system is a waste of time, and they immediately fill in new antifreeze or antifreeze after draining the spent fluid. In this case, a mixture of clean and dirty liquid occurs, negatively affecting performance.

You can flush the cooling system both with water and with the help of special means.

Flushing the OS with water

Flushing the cooling system with water is allowed only if there is no flushing fluid. The fact is that in ordinary water there are impurities that contribute to the formation of scale. If the choice is on water, it is better to use distilled water.

Sequencing:

Flushing the OS with a special tool

You can also flush the cooling system with a product with special impurities. This is a more expensive way to clean the system, but in the long run the most appropriate option, since the tool removes from the tank:

• body fat;
• dissolves and removes scale from the tank;
• organic compounds.

Today, owners of a VAZ 2107 car use flushing fluids, the two main components of which are acids and alkalis. Car owners prefer the LAVR tool, the cost of which is from 700 rubles.

The sequence of actions when flushing the cooling system with a special fluid does not differ from flushing with water. The only significant difference is the operating time of the motor, which is indicated on the canister with liquid.

After flushing the VAZ 2107 radiator tube with LAVR, a positive result is obvious.

gulf

After the actions taken, it is time to fill in a new antifreeze (or antifreeze, if such a decision was made by the VAZ 2107 car owner).

How to replace antifreeze with a VAZ 2107 injector? Sequencing:

• Open the radiator cap, insert a funnel there;
• The following actions are carried out with the help of a partner. The plug is removed from the cylinder block, antifreeze is slowly poured. At the same time, start the bolt, and as soon as the antifreeze from the BC flows, the bolt is tightened. Such a maneuver will help eliminate the creation of air jams;
• Pour antifreeze into the radiator until it is completely filled;
• Pour antifreeze into the expansion tank until it reaches the radiator. After screwing the tank cap;
• The tank is filled last. Level - corresponding to the norm. At the end of all procedures, the lid is screwed on;
• Start the engine and warm up to operating temperature to check the correct operation of the cooling system. The cooling fan should work, and the temperature should drop, which means the system is in working order.

This completes the replacement of antifreeze in the VAZ 2107 injector. There is no need for special knowledge or special equipment to perform this procedure. It is enough to have a set of tools and decide on a place.

It should also be noted that antifreeze, like antifreeze, is a toxic substance. Therefore, it is observed a number of safety measures when replacing coolant with a VAZ 2107:

• Do not drain antifreeze on the floor in the garage or on the ground in the yard. The liquid is poisonous, it can harm the human respiratory system;
• Protect the skin, do not allow antifreeze to get on hands or in the mouth. A number of motorists check the nature of the fluid used by dipping a finger into the tank. The consequences may be poisoning or burns;
• If antifreeze gets on your hands, face, eyes, or mouth, rinse with cold water and take the victim to a specialist, or call an ambulance. Antifreeze, like antifreeze, is primarily a liquid hazardous to health, and only then a necessary component for the proper operation of a VAZ 2107 car;
• Do not have a snack during the work on replacing antifreeze in the VAZ 2107. In this way, you can swallow the evaporated poisonous liquid;
• Wash your hands after completing the antifreeze replacement procedure. This is done several times, with running water, after which the skin should be protected with a special cream (especially relevant if antifreeze gets on the skin of the hands).

The choice of antifreeze and antifreeze for the VAZ 2107

Considering the advantages given earlier, most motorists opt for antifreeze, because saving on coolant will lead to the need for engine repair.

For VAZ 2107 antifreeze is suitable for both domestic and Western production. The owners of this brand of car prefer, for the most part, Lukoil G12 RED antifreeze.

The most inexpensive domestically produced coolant is A40M antifreeze.
