How to replace antifreeze on a VAZ 2110: how many liters of antifreeze are included in the cooling system, replacement instructions

During normal engine operation, without overheating, gasket failures and other unexpected troubles, the coolant can last for 150,000 km without loss of physical characteristics. However, it must be replaced in a number of unforeseen cases, as well as during scheduled maintenance, carried out either in a service center or in a garage. In this case, we have some tips.

Functions and features of antifreeze

All cars, without exception, including the VAZ 2110, use coolants to stabilize the engine temperature and maintain normal operating temperature. When the liquid loses its performance qualities, then it is necessary to replace the VAZ 2110 antifreeze, as all antifreezes are mistakenly called.

Antifreeze is a brand of antifreeze developed in 1971 by the All-Union Scientific Research Institute of Organic Synthesis Technologies. We inherited its name from our dark ancestors, who cooled their engines exclusively with water from wells and sipped cabbage soup with bast shoes. At that time, there was no antifreeze that would satisfy the requirements of the new VAZ 2101 engine, and the Italians, who developed and prepared it for production, flatly refused to guarantee normal operation of the engine using local antifreeze. Therefore, there was a need to develop a modern domestic coolant specifically for the new Zhiguli. So a whole generation began to call all antifreeze antifreeze. This is fundamentally wrong, and some bloopers are still speculating on this, passing off cheap dubious liquids as high-quality antifreeze.

When to change coolant

The first signs that the antifreeze needs to be changed cannot be ignored. It begins to foam, resulting in air pockets in the cooling system. This in turn leads to overheating of the engine, which does not bode well. Also, the unsuitability of antifreeze for further use can be indicated by an oil film on its surface and a characteristic rusty color. Replacing the coolant is also advisable if the engine was disassembled for a major overhaul and when there were cases of oil leakage into the water jacket.

Replacing antifreeze on a VAZ 2110

The process of replacing antifreeze is simple, you just need to do all the steps sequentially, and remember that coolant is poison. Handle it more carefully and wear gloves when replacing it. All work on replacing antifreeze is carried out only on a cold engine. The work flow is as follows:

A horizontal position of the car is desirable, but if there is a slope, it is better to place it so that the front is higher. It is better, just in case, to disconnect the negative terminal from the battery and be sure to remove the cap from the expansion tank of the cooling system.
The fluid is drained from the cylinder block quite simply on models 2110 and 2111, but on 2112 you will also have to remove the ignition module along with the bracket.
We will place a container under the engine in the area of the plug to drain the antifreeze. We unscrew the plug, drain the antifreeze, tidy up the engine compartment using a rag, since the drain hole is designed so that the antifreeze will remain not only on the cylinder block.
We move the container under the radiator and carry out the same operation with the drain hole in it. Let's be careful, because in this place the designers showed special care for the user. Old antifreeze spreads over the beam, it can soak the generator and the engine mounts will also have to be scrubbed. Antifreeze must leave the system to the last drop.
The next step is very important, because if you forget about it, air pockets may form in the system. If the engine is carburetor, then you just need to disconnect the hose from the intake manifold heating fitting. In injection models, the hose is disconnected from the throttle pipe.
Pour antifreeze into the system until its level reaches the upper edge of the expander mounting clamp and screw the plug tightly.
We connect the heating hose in place: either on the manifold or on the throttle pipe if the engine is injection.

We start the engine and warm it up to operating temperature. We turn it off, check the level, and, if necessary, top up to the required mark. We wrap the plug tightly, not forgetting that the cooling system is sealed.

Recommendations for choosing coolant

Any antifreeze is suitable for a VAZ 2110, you just need to take into account the fact that they are painted in different colors for a reason. At first, manufacturers tried to mark liquids according to the freezing temperature threshold in this way, but there weren’t enough colors for all manufacturers, so now the color of antifreeze means almost nothing, but mixing antifreeze from different companies is highly not recommended.

The VAZ 2110 system needs to be filled with 7.5-8 liters of liquid, but it is better to buy a ten-liter container at once so that there is antifreeze left for topping up. Don't overheat the engine, and good luck on the road!

Required amount of coolant for VAZ 2110

After a certain mileage and operation of the VAZ 2110 car, it is necessary to carry out a technical inspection, monitor the level of oil and coolant in the system. After a certain period of operation, all lubricants and coolants lose their original technical and operational characteristics and require replacement. Therefore, before replacing the coolant, you need to find out how much antifreeze is in the cooling system of the VAZ 2110.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

Many inexperienced car enthusiasts, when replacing antifreeze or antifreeze in a car's cooling system, fill in 5-6 liters of fluid and make sure that it has reached the maximum level in the expansion tank, consider this sufficient and close the hood of the car. This is their big mistake , since the antifreeze has not yet had time to completely fill the system. You need to wait about five minutes until the liquid level in the tank drops significantly. Accordingly, you will need to add more coolant.

We recommend: Do-it-yourself connection of fog lights via a relay

This procedure must be done several times, only then will it be clear how many liters of antifreeze are in the VAZ 2110 cooling system. It is necessary to add fluid until its level stops at one mark, which should be above the minimum and below the maximum level. Not adding enough antifreeze or antifreeze can cause the engine to overheat and fail. It is also impossible to overfill coolant, since when heated it tends to increase in volume.

After pouring antifreeze (antifreeze), you need to perform the following steps:

close the expansion tank cap;
start the engine and wait until it warms up before turning on the fan;
turn off the engine and let it cool down;
Check the coolant level in the tank and top up if necessary.

A VAZ 2110 needs to be filled with approximately 8 liters of coolant. This is a rather important procedure on which the life of the car engine depends.

Location of expansion tank

A plastic reservoir for excess coolant is installed by the manufacturer in different places depending on the model of the “tenth” family:

in cars of the VAZ 2110-12 series, the reservoir is located on the left side (in the direction of travel) between the pillar glass and the wall of the interior partition;
in VAZ 2114-15 cars, the container is also located on the driver’s side, but is placed in front of the pillar glass.

The expansion tank is attached to the body elements with a clamp in the form of a flat rubber belt with a metal hook that hooks onto a protrusion on the side member. There are 3 hoses connected to the tank:

A large diameter pipe leading from the thermostat is connected to the bottom.
The upper tube of small diameter goes through the partition to the radiator of the cabin heater.
The middle small tube connects the tank to the upper fitting of the main cooling radiator.

Each hose performs a separate function. The thick pipe serves to expand the coolant and fill the system while pouring antifreeze through the neck of the tank. Two thin tubes are designed to drain the steam-water mixture from the stove and the main radiator into the tank when heated to the maximum permissible antifreeze temperature of 95 ° C.

The expansion tank (item 1) is located at the highest point of the cooling system at the same level as the throttle valve

When is it necessary to change the coolant on a VAZ-2110

There are no specific regulations for replacing the cooling system fluid and there are several reasons for this.

Dirty coolant in the expansion tank.

The type of coolant greatly affects its service life and this must be taken into account.

For example, inexpensive liquids based on ethylene glycol can last up to one and a half to two years .
More modern antifreezes of class G12, G12+, G13 can easily last up to 4 years.

However, the replacement period may be dictated by the condition of the fluid:

oily spots on the surface of the liquid;
complete loss of color;
foreign particles in the expansion tank;
foaming and frequent boiling of antifreeze;
loss of density due to frequent addition of distilled water.

These signs will indicate that it is time to change the antifreeze.

Inspecting the reservoir and the condition of the coolant (color, shape, dirt and foreign impurities) should become a habit!

Antifreeze selection basics

For replacement, we select, if possible, the same antifreeze that was originally poured into the engine.

Otherwise, the cooling system must be flushed , since mixing antifreeze of different brands and even different manufacturers can lead to sedimentation, clogging of the cooling system and the antifreeze losing its lubricating, cooling, flushing and antifreeze properties.

Draining antifreeze from the VAZ-2110

Before draining antifreeze or antifreeze from a VAZ-2110 car, you need to find a suitable site for work. This could be a garage or other flat area. If you do not have the opportunity to carry out work indoors, then you can install the car so that its front part is slightly higher than the rear. Next follow the instructions:

Disconnect the negative terminal of the battery to de-energize the vehicle.
Remove the ignition module with bracket.
To increase the pressure in the cooling system, it is necessary to remove the expansion tank cap.
Next, install a wide, cut canister or bucket under the power plant into which you will drain the coolant that has expired.
Unscrew the antifreeze drain plug on the engine block. After this, you will only have to wait until the coolant is completely removed from the system. Wipe the plug and drain hole with a rag.
Repeat the procedure with the radiator. Place the bucket and unscrew the cap on its bottom. Wait until this unit is empty, then wipe the drain hole and plug with a clean rag.

If your VAZ-2110 has an injection engine with 16 or 8 valves, when draining the antifreeze, you must carefully remove the antifreeze supply hose from its connection with the throttle pipe heating fitting. To do this, you will need to loosen the clamp holding it.

On cars with an engine equipped with an injection system, it is necessary to remove the hose at its connection with the carburetor heating fitting. The steps described for each engine will help you get rid of air locks in the system.

How to remove an air lock from the cooling system of a VAZ 2110, 2112

1.If the car has recently been running, then you need to wait until it cools down. 2.Unscrew the cap of the expansion tank, only with the engine cooled down, otherwise antifreeze under pressure may splash out. 3. Disconnect the coolant supply hose from the throttle pipe heating fitting if you have an injector. Or disconnect the hose from the carburetor heating fitting if you have a carburetor. 4. Fill antifreeze into the expansion tank to level 5. Attach the hose back.

Coolant selection

First, you need to figure out how much coolant is provided in the VAZ 2110. This will allow you to purchase the required amount of antifreeze and correctly carry out the replacement procedure.

New coolant

So, the expansion tank should be filled with 7.8 liters of coolant. Although in reality, when draining, you will only get about 7 liters. Part remains inside. Therefore, when filling, there is no need to fill all 7.8 liters. 7 liters is enough.

We have already understood how much coolant is provided in the VAZ 2110, and how much needs to be filled. So it's time to choose.

In order to make a smart purchase of a new antifreeze, follow a few simple rules.

Purchase a liquid with the same characteristics, color and production that was used previously. Of course, if the previous coolant worked effectively. Mixing different types of antifreeze is a common mistake that can lead to unpredictable consequences.
Take a closer look at the packaging of the liquid you purchased. Today they sell both ready-to-fill formulations and concentrates, which must be diluted before use.
Replace antifreeze only when the engine has completely cooled down.
Start the engine after replacing the coolant strictly after all connections are made and the expansion tank cap is closed.

Preparing to replace antifreeze

Before changing antifreeze, you need to drain the old one, and this is completely logical. In total, the tank contains approximately 7.8 liters of antifreeze. You can drain 7 liters without any problems. This means that for replacement you will need only 7 liters of fresh antifreeze.

Choosing antifreeze important features:

It is best to buy antifreeze from one manufacturer. If there is a strong difference in composition, the mixture in the tank may not be very good. And this can damage the health of the car.
You need to pay attention to the type of liquid. If it is a concentrate, then it will definitely need to be diluted.
It is necessary to replace the coolant after the car has completely cooled down. And it will be possible to start the car only when everything is finally connected and checked for leaks. Otherwise all the problems will come out again.

Nuances of antifreeze

There are many opinions as to whether antifreeze is actually better than antifreeze. We will not prove our position, but rather we will tell you a few facts.

Why is it better to use antifreeze when replacing coolant in a VAZ 2110? The choice is always up to the car owner, but this particular coolant has a wide range of advantages:

When heated, the degree of expansion of antifreeze is less than that of water. Therefore, the presence of even a small gap for expansion will allow it to protect the system from rupture and maintain the integrity of the pipes and caps of the expansion tank;
The boiling point is higher than that of water;
At sub-zero temperatures, the coolant does not turn into ice and acquires a gel-like structure, which does not lead to rupture of the cooling system (CO);
Does not form foam;
Does not cause corrosion. Moreover, it has the function of preventing its occurrence.

Sensor diagnostics

All car owners should know how to check the temperature sensor on a VAZ-2110. By checking, you can save on the cost of a new device, although its price is not entirely high.

You can test the element by heating it. You need a suitable container. It could be a glass or a teapot. Hot water is poured into it. The water should be heated to approximately 100 degrees - the heating should be monitored with a thermometer. Next, the working part of the device is lowered into water. However, it is precisely the part of the temperature sensor that is located in the motor that needs to be lowered. Contacts must not be in water. Then a multimeter is connected to the contacts and the resistance is measured.

A working sensor at a liquid temperature of 100 degrees has a resistance of 177 ohms. At +50 degrees the resistance is 973 Ohms. If the values do not correspond to the norm, then the faulty element should be replaced. If the indicators are within these norms, then everything is in perfect order.

Procedure for replacing fluid in the cooling system

Before adding any coolant, close the engine and radiator caps, and then fill the system with antifreeze. It will be required so much that the liquid level in the expansion tank reaches the point where the belt fastening passes.

Upon completion of work, tightly screw the cap of the expansion tank and return the hose leading to the heating system. Please note that high pressure occurs in this assembly. If you do not tighten the plug tightly enough, it may break off during operation. This will inevitably lead to antifreeze leakage.

Before starting the engine, perform reverse assembly - install the ignition module and return the negative terminal to the battery. After the work described in this section, you can start the engine to warm up. You shouldn’t start driving right away - let the engine run for a while, and then check the fluid level in the expansion tank. If there were air pockets in the system, the amount of antifreeze will decrease. The top edge of the fluid will not reach the location of the belt on the reservoir. In this case, let the car sit for a while and then add antifreeze.

Sometimes, by warming up the power plant, the air plugs are not pressed through. In this case, it is necessary to repeat the procedure with the hose (described in the previous section), at the same time open the cap of the expansion tank. After excess air has escaped, it is necessary to add antifreeze to the required level.

Stages of work with replacing coolant in a VAZ 2110

Before starting the main stages of work, it is necessary to prepare the work surface, tools and equipment.

During such work, the vehicle is placed on flat surfaces or at a height. The engine must be completely cool.

The replacement process will require small containers, 8, 13 and 17 wrenches, water and new antifreeze.

Replacing antifreeze with antifreeze in a VAZ consists of the following steps:

coolant drain;
flushing the system;
filling in new refrigerant.

In VAZ 2109, 2111, 2114 models, flushing the cooling system is not necessary. It is only required if the drained antifreeze was contaminated with rust or scale.

In models VAZ 2111, 2109, 2106, 2110, before replacing, it is necessary to disconnect the negative terminals of the battery so that a short circuit does not occur when draining the antifreeze.

In models 2110, 2112, 2115, after draining the fluid, the car should be started and the engine should be left running for 4-5 minutes so that all the fluid is pumped through and out of the system. Without this moment, the remaining antifreeze, which is not removed independently, will mix with the antifreeze and can lead to engine damage.

Draining antifreeze

It is best to drain the liquid at a height: the car should be placed on a lift, overpass or above a repair pit.

Before draining antifreeze on a VAZ 2110 and other models, make sure that the system has completely cooled down.

Draining is quite simple:

A container for old antifreeze with a volume of 10 liters or more is placed under the car.
The cover is removed from the expansion tank of the system and the drain plug is unscrewed from the cylinder block with a key set to “13”.
During the process, the plug can be supported so that it is not blown away by the pressure of the liquid.

When the antifreeze is drained from the VAZ block, the plug is screwed back on. The next step in draining is draining the antifreeze from the system radiator. The process is carried out in the same way as with the cylinder block. You can also tighten the cap on the radiator yourself, without any equipment or tools.

Flushing the system

Flushing, as a step when replacing antifreeze, is necessary if the car is already very old and the cooling system has never been cleaned. On the other hand, the risks increase that if you flush the system during replacement, you can clog the radiator, thermostat and heater radiator.

Washing is carried out as follows:

old antifreeze is drained;
all plugs are screwed into place;
Distilled water is poured into the tank to the maximum level;
the engine starts and warms up to operating temperature;
the working engine is left for 5-10 minutes;
the car turns off and cools down;
After cooling, the water is drained from the tanks.

If the water remains dirty when draining, the operation must be performed several times until it becomes clean.

Filling with new antifreeze

When adding new coolant, you will need about 9 liters of new coolant. Ideally, antifreeze in a VAZ 2110 should be replaced every five years, but on older models it is better to change the fluid every second year.

Filling in new antifreeze occurs step by step:

The drain plugs are screwed in;
The hose on the throttle assembly is unscrewed;
New fluid is gradually poured in;
You should stop when the antifreeze reaches the extreme level;
The hose is twisted;
The liquid is added to the maximum mark;
The tank closes and the engine with the stove starts;
The engine warms up to operating temperature and turns off;
The replacement has been made.

The procedure is standard, but not suitable for all systems. How to change antifreeze to antifreeze in a VAZ with 16 valves? The procedure is carried out differently. After the liquid is poured into the tank, air is removed through the expansion tank, then the car starts and you need to drive it for several kilometers. The system is checked again and the liquid that has escaped is added.

Why is it worth switching from antifreeze to antifreeze: pros and cons

What is better: antifreeze or antifreeze and why it is worth replacing one with the other - these are questions that many drivers of domestic cars ask.

The advantages of antifreeze in these matters are obvious:

high boiling points;
long service life;
cleans the cooling system;
produced for long mileage.

Antifreeze is a cooler that was created for the domestic auto industry, and for many years it served our cars. However, antifreeze had to be changed every 2 years, and antifreeze is designed for 5 years of operation.

In fact, antifreeze and antifreeze are the same thing. Only the latter is an improved version of the liquid. It follows from this that replacing the refrigerant in a VAZ is an important procedure that has a positive effect on the operation of the engine and other components.

When you decide to replace antifreeze with antifreeze in your car, follow the instructions, because the slightest mistake can lead to major damage to the car’s systems.

Optimal coolant option

When we figured out how to replace antifreeze on a VAZ 2110 (2112),

It is important to choose the optimal liquid option . Many car enthusiasts only use expensive antifreeze, considering it to be of higher quality. For VAZ cars, it is quite possible to use a cheap domestic product - antifreeze, the characteristics of which were developed specifically for these cars.

Owners of domestic cars respond positively to Felix brand antifreeze. It is sold in canisters of 5 and 10 liters, and smaller containers. It is profitable to purchase liquid in a 10 kg container - it is cheaper, and after replacing the used antifreeze, there is still liquid left for refilling.

How to change antifreeze on a VAZ 2110 with your own hands

Replacing antifreeze on a VAZ 2110 is a very important procedure. Coolant is very important to the operation of any vehicle. Without this fluid, the car simply cannot function fully. During operation, the engine gets very hot, and without antifreeze, it boils. Also, antifreeze protects the engine itself well from corrosion, which greatly increases the life expectancy of the car.

We drain the antifreeze ourselves

To drain antifreeze and fill in new fluid, we need a drain container with a volume of at least 7.5-8 liters.

You will also need keys and flushing fluid if the system needs to be cleaned.

To refill the system, 7–7.5 liters of finished liquid . This must be taken into account if we pour the concentrate and dilute it with distilled water. It is advisable to carry out the work with gloves, since antifreeze is toxic. Before replacement, we will conduct a detailed inspection of the system, eliminate fluid leaks, and replace failed pipes and clamps.

Algorithm

We carry out replacements on a cold engine according to the following algorithm:

We place the car on a level surface; if possible, we place the car so that its front part is slightly higher than the rear.
Remove the negative terminal from the battery.
We install the heater valve in the extreme right, hottest position.
Turn the heater control knob to the right until it stops.
Remove the engine protection, if installed.
Unscrew the screws securing the engine protection.
Disconnect the wires from the ignition module and remove it to provide access to the drain plug on the cylinder block.
Disconnect the connector.
Unscrew the fastening bolts.
We take out the ignition module.
Remove the plug from the expansion tank.
We place a container under the radiator drain plug, unscrew it and wait until all the liquid flows out.

Unscrew the plug at the bottom of the radiator.
Place a container under the cylinder block plug. We are waiting for the old fluid to be completely removed.
Using a 13 key, unscrew the plug on the front side of the cylinder block.
After draining the antifreeze, wipe the cylinder block and radiator with a rag, replace the block plug and tighten the plug on the radiator.
Remove the throttle body heating hose. This will avoid the formation of an air lock in the system.
Disconnect the fluid supply hose to the throttle body.
Fill the expansion tank with new antifreeze to the maximum level and screw on the cap.
Fill with antifreeze to the required level.
We put the hose in place on the throttle assembly.
We put the ignition module in place and screw the negative terminal to the battery.
We start the engine; as it warms up, the fluid level may drop. In this case, we will add fresh antifreeze to the required level.
Warm up the engine to operating temperature.
We check the system for leaks.
Check the coolant level in the expansion tank.

General cooling system maintenance tips

First of all, you need to adhere to the following safety tips:

Cool the car completely; its engine should be completely cold.
Remember that antifreeze is a fairly toxic liquid, so you should not allow it to get into the stomach, skin or eyes. Wear gloves when working.
After you fill in new antifreeze, you can start the car only after installing the expansion tank cap in place.

If you have replaced the heater core, you need to check the operation of the fan. To do this, monitor the coolant temperature on the dashboard. If the arrow reaches the red zone and the fan still does not turn on, you need to turn on the airflow from the heater. Cold air indicates an air lock, and hot air indicates a fan malfunction.

You can remove the plug from the air when the power unit is turned off and cooled; to do this, you just need to unscrew the cap of the expansion tank.

When to change coolant

Not all motorists know what the life cycle of antifreeze is. It is approximately 150 thousand kilometers. In theory, maybe more, but it’s better not to risk it and, for the sake of prevention, change it even more often.

Drain plug

There are several situations that will require you to carry out a mandatory coolant replacement procedure.

The color of the coolant has changed. The liquid may take on a rusty color. This indicates the need for replacement.
An oil film has formed on the surface of the cooler.
Antifreeze often bubbles in the expansion tank of a VAZ 2110. Moreover, there were no prerequisites for such a phenomenon. The Ten is a car for good speeds, because when driving at low speeds, the antifreeze in the expansion tank on the VAZ 2110 often boils. This is because the cooling fan does not turn on.
A coolant that is no longer suitable for further use may also boil, the composition of which has changed significantly since it was poured into the expansion tank.
Antifreeze is leaking somewhere from the expansion tank on a VAZ 2110. The situation is common, but it cannot be solved by adding or replacing coolant. It is necessary to find where the antifreeze is leaking from the expansion tank of the VAZ 2110. Usually the leak is found on the clamps, although it would not be a bad idea to check the entire system.
The coolant level may be normal, during operation it does not emit antifreeze from the expansion tank of the VAZ 2110, the color is normal, but still the boiling process occurs quickly. Most likely, the reason lies in the airlock.

Coolant VAZ 2110: correct selection and replacement

Replacing (topping up) coolant in a VAZ 2110

The duration of use of the coolant (its service life) ranges from 120 thousand kilometers to 150 thousand kilometers; upon reaching such a mileage, it is necessary to replace the VAZ 2110 16 valve coolant. The main sign indicating the need to replace antifreeze (antifreeze) is the appearance of a rusty color in the coolant expansion tank, or an oil film, or any other deviations from its initial state. Replacing the coolant in a VAZ 2110 8 valve is a simple procedure, no different from replacing the antifreeze in a VAZ 2110 16 valve, and anyone can do it themselves.

How to change coolant

Before replacing antifreeze, you need to know that this can only be done on a cooled engine. Antifreeze and antifreeze are aggressive chemicals that can cause harm to the human body, therefore, follow safety precautions and carry out all work with gloves. You can start the car after changing the fluid only after you make sure that the reservoir cap is tightly screwed on.

Drain the coolant

Many drivers are interested in how to drain antifreeze from a VAZ 2110 and do it quickly and correctly.

Before you start changing the antifreeze, you need to place the machine on a horizontal platform. And if this is not possible, then make sure that the back is slightly lower than the front.

Disconnect the negative terminal from the battery.
Together with the bracket, remove the ignition module.
Ignition module
We unscrew the cap of the expansion tank, having previously installed a 10 liter capacity to drain the used coolant.
Draining old fluid
Drain the cooler.
We wipe the cylinder block from any remaining fluid.
We tighten the plugs of the radiator and cylinder block.

Filling with coolant

Before disconnecting the coolant supply hose, loosen the clamp.
If the engine is equipped with a carburetor, then you need to disconnect the hose from the fitting so that air can escape during filling.
We begin to pour antifreeze into the system (about 7-8 liters will be needed) until its volume reaches the level of the upper line of the expansion tank fastening belt.
We pour new antifreeze through the funnel
Be sure to tighten the plug tightly, otherwise if the coolant boils, it may splash out.
We connect the hose.
We put the ignition system in place.
Connect the “-” terminal to the battery.
We start the engine and wait for it to warm up to operating temperature.
Liquid level in the tank
We look at the position of the sensor pointer and the level in the tank;
After a few days, it is advisable to check and determine whether the coolant level in the expansion tank is normal.

How to replace antifreeze on a VAZ 2110,2112 yourself

First, let's find out why we need to replace coolant on a VAZ 2110 if we constantly monitor its level and regularly top it up to the mark on the expansion tank. But it's not that simple. It is important to know that antifreeze, after prolonged use in the cooling system, changes its properties. If this is not critical in the summer, then in winter it can freeze and rupture both the radiator and the cylinder block. Long-term operation of the coolant is considered to be a mileage of more than 70 thousand kilometers or 4-5 years of operation. So let's get started.

It is necessary to replace antifreeze only when the engine has cooled down.
Coolant is an active chemical, so you need to be careful when changing it.
Before starting the engine, make sure that the expansion tank cap is tightly closed.

1. It is best to replace antifreeze on an overpass or pit intended for repairs, so that there is free access to the bottom. But if this is not possible, then we place the car on a flat surface. If the site has a slope, then we park the car so that the slope is backwards. 2. Disconnect the wire from the battery terminal. 3. Before starting to replace the antifreeze, make sure that the engine has cooled down sufficiently. 4. To get to the drain hole on the cylinder block of model 2111, remove the ignition module along with the bracket (Fig. 1).

5. Next, remove the cap of the expansion tank so that a vacuum does not form in the cooling system and the antifreeze comes out completely (Fig. 2).

6. Place a container for draining the coolant under the cylinder block and unscrew the drain plug on the cylinder block. After the antifreeze is completely released, we wipe the cylinder block from antifreeze residues (Fig. 3).

7.Next, install the drain container under the cooling radiator. We unscrew the drain plug on the radiator and wait until the antifreeze is completely out of the cooling system (Fig. 4).

8.If you have an injection system, then loosen and tighten the clamp and disconnect the antifreeze supply hose from the throttle pipe heating fitting (Fig. 5).

If you have a carburetor, then disconnect the hose from the carburetor heating fitting (Fig. 6)

This procedure is necessary so that when the coolant fills the cooling system, air comes out of it and an air lock does not form. 9. Fill the cooling system by pouring antifreeze into the expansion tank until its level is at the top edge of the fastening belt. Screw on the expansion tank cap. The cap of the expansion tank must be screwed on tightly, because when the engine is running, the tank is under pressure and antifreeze may leak from under the plug, or it may simply be torn off (Fig. 7)

10. We connect the hoses, depending on the model, to the heating fitting of the throttle pipe or carburetor 11. On the cylinder block of model 2111, we install the ignition module in place. 12. Connect the wire to the battery terminal. 13. Next, start the car, let it warm up to operating temperature and turn it off. Check the coolant level and, if necessary, add to the level

When starting the engine for the first time, after replacing antifreeze on a VAZ 2110, 2112, it is necessary to monitor the coolant temperature. If the temperature gauge needle moves to the red zone and the fan does not turn on, turn on the heater and check what kind of air flows through it. If it is heated, then most likely the fan is faulty; if it is cold, then an air lock has formed in the cooling system.

Replacement features

If there are small leaks in the engine cooling system and the car owner periodically adds water or antifreeze from different manufacturers, the old coolant may take on a rusty color. Foreign bodies may appear in the form of small chips and rust, which, by the way, can lead to failure of the main elements of the cooling system, water pump, thermostat, heater tap, etc.

Flushing the VAZ 2110 cooling system

In this regard, when replacing old antifreeze in this condition, it is necessary to flush the system. This can be done using different additives, which is not always beneficial for the cooling system. Low-quality cleaning additives may not only not help, but also damage the components of the cooling system. Therefore, it is necessary to use high-quality additives and not skimp.

You can also flush the system naturally with distilled water. After draining the old antifreeze, water is added. The car idles for 10-15 minutes, then it is drained again and new antifreeze is added. If there is severe rust, you can repeat the procedure.

There is a cheaper and easier way; you can simply flush the system with plain water by opening the radiator and engine caps in sequence. Those. the engine cap is unscrewed and water is spilled through the expansion tank. Then the engine plug is closed and the radiator drain plug is opened. Do only in this sequence, since the radiator is at the lowest point and all the water will pour out.

Has everything merged?

Removing all the refrigerant from the system is quite problematic, because it is a whole complex of channels, tubes and hoses. In general, this is not required during normal routine replacement, but if, for example, you are going to replace antifreeze with antifreeze, or vice versa, or flush the cooling system, you will have to try to remove the liquid from the engine as much as possible. But how to completely drain the antifreeze? The VAZ-2110 is not such a difficult car for this. This can be done using a regular car compressor, or, as a last resort, a pump.

We take the compressor, connect its hose through some homemade adapter to one of the “nipple” on the expansion tank, having first removed the hose from it and “plugged” it, and begin to pump air into the system. Almost all the liquid remaining in the hoses, engine cooling jacket, and radiator tanks will come out through the drain holes.
