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: How to fix a dent on a car with your own hands?

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.

Safety rules when replacing antifreeze

It is worth remembering that antifreeze itself is quite toxic, and breathing it is quite dangerous, it also has a bad effect on the mucous membranes of the nose and eyes, and you can get a lot of burns with its help.

The main rule for changing antifreeze is that the engine must be cold.

, otherwise harmful fumes will get on your face, and the consequences cannot be avoided.

Try also not to touch the antifreeze, as after this, through negligence, you can accidentally transfer some of it to your face.

If you accidentally spill coolant, simply wipe it off with a damp cloth or tissue.

When replacing antifreeze, remember that you need to change it not only in the cold, but also in the warm season, this way you will protect yourself not only from the fact that the car may not start in the cold, but also from boiling liquids. It needs to not only be changed, but also periodically topped up, because an insufficient amount of it causes it to boil, which has a bad effect on the operation of the car. Caution when working with the machine is the main thing, because it is filled with many liquids harmful to humans.

Antifreeze is a special liquid designed to cool a car engine. It is poured into the expansion tank of the system, located under the hood of the car. The fluid requires periodic replacement, since after a certain period of engine operation it loses its original properties. Therefore, young car enthusiasts are interested in how much antifreeze is in the VAZ 2110 cooling system.

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.

Note to car owners

Please know that if you do not replace the antifreeze in a timely manner, then premature corrosion begins in the channels of the engine block and its head and, as a result, the engine life is significantly reduced:

This affects the cylinder head the most.
Working as a car mechanic, I often had to disassemble engines and observe the head cooling channels eaten away by corrosion
After such a spectacle, anyone will feel scared for their car; you will certainly forget to change the antifreeze in a timely manner.
At each scheduled maintenance, you need to check the level and appearance of antifreeze (more often if possible)

Important: The antifreeze level must be checked on a cooled engine; the permissible level is within (between) the lower and upper marks on the body of your expansion tank. A slight increase or decrease in this level that occurs when it is cooled or heated is not considered a malfunction; this is absolutely normal. Such level fluctuations are associated with thermal changes in volume (for example, expansion when heated and subsequent decrease in volume when cooled). However, if you notice a gradual decrease in the level with each new check on a cold engine, then you need to look for where the leak is occurring.

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 carburetor 4. Fill the 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.

Is there a difference in the processes of draining antifreeze in eight- and sixteen-valve engines?

There is a difference, and it is significant. The fact is that the “tens” engines have different designs. In terms of draining antifreeze, a VAZ-2110 with 8 valves is more profitable than a dozen with sixteen valves.

The first has a coolant drain plug located on the front of the cylinder block. To get to it, you don’t need to drive the car into the inspection hole or remove the protection. But for sixteen-valve power units, the plug is located at the bottom, and can even be closed by the starter, so before draining the antifreeze from the VAZ-2110, you will need to drive the car into a pit (overpass), remove both the protection and the starter.

Necessary tools and means:

keys for 10 and 13;
funnel with a hose (can be made from a plastic bottle);
container for collecting old refrigerant (canister, bucket);
additional capacity for 2-3 liters (you can use a cut-off plastic bottle);
dry rag.

Before draining the antifreeze from the VAZ-2110 block, it is necessary to position the car so that its rear part is slightly raised. To do this, you can park the car downhill, or drive the rear wheels onto the curb. This will allow the coolant to drain faster.

It is also advisable to remove the negative terminal from the battery, especially if you are dealing with an injection engine. Next we follow this algorithm:

Unscrew the cap of the expansion tank.
We place a funnel under the drain hole and lead the hose through the engine protection to any convenient place where you can place a container to collect the refrigerant.
Using a 10mm wrench, carefully unscrew the drain plug and wait for the coolant to drain.
After this, we place an additional container under the radiator cap.
Unscrew the plug and drain the remaining refrigerant.
When all the liquid has drained, tighten the plugs and we can start pouring new antifreeze.

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.

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.

Replacement

To change antifreeze, you must first drain the old one:

Wear rubber gloves and protect your eyes. Naturally, do not touch the reservoir cap if the engine is boiling.
Place the car on a level place. Some experts argue that it is even better if the front end is raised a little - this way more fluid can be drained - it leaves the system better.
De-energize the VAZ 2110 by removing the negative terminal from the battery.
Remove the ignition module together with the bracket. This way you gain access to the cylinder block. Place a suitable container under the drain plug to collect the antifreeze.

Install the container and unscrew the drain plug on the cylinder block

Removing the cap from the expansion tank

Place a container under the radiator to drain the coolant and unscrew the radiator drain plug

Loosen the clamp and remove the coolant supply hose from the throttle pipe heating fitting

If it is a carburetor, also remove the hose at the junction with the fitting for heating the carburetor. It is these actions that are necessary to prevent air jams from forming.

Remove the hose from the carburetor heating fitting so that the air comes out and there are no air pockets

Fill coolant to the level in the expansion tank

After the replacement is made, you need to tighten the expansion tank cap tightly (this is important!). Return the removed hose to its place, reconnect the ignition module, return the removed wire to the battery, and you can turn on the engine. Let him work a little.

Sometimes the coolant level in the tank drops. This means that there was a plug somewhere, and it “pressed through” (you checked the fastening of all the hoses!). You just need to add antifreeze to the optimal volume.

Have you already used such a gadget?

I use a hose that fits the diameter of the holes in the radiator and block, opened the conservator cap, relieved the pressure, immediately closed it, because in this case the antifreeze does not gush out under pressure (provided the system is sealed), then I unscrew where it needs to be drained from and immediately insert the hose, then the conservator I open it. With a bottle from the radiator it’s understandable, but from the block I can’t even imagine when it ends up flowing along the wall of the block.

Most of the coolant is drained through the remote control heating hose. I haven’t tried it myself, but I know this method.

Welcome, friends, to the DIY car repair website. Many car enthusiasts, having driven their cars for several years, have not changed the engine cooling fluid or antifreeze.

Of course, they constantly monitor its level using a mark on the expansion tank, and if it decreases, they add the required amount. However, topping up is not a replacement.

replacing antifreeze VAZ 2110

It is necessary to understand that by exceeding the period of use of antifreeze in the engine cooling system, you thereby change the properties of the liquid, and it gradually ceases to perform its functions.

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.

How to change antifreeze on a Priora with and without air conditioning

In order to replace it with Priora, prepare the following:

about 8 liters of coolant;
free capacity of about 10 liters;
crosshead screwdriver;
key to 13.

Before draining antifreeze on a Priora, wait until the engine and coolant have cooled down: there is a very high risk of burns. Carry out the work in the following order:

Drive the car into the pit, stop it and remove the negative terminal from the battery.
Remove the engine crankcase protection and the expansion tank cap.
Place a large container under the engine, crawl down and unscrew the drain plug using a 13mm wrench.
When the liquid - antifreeze - flows out, screw the drain plug back in, move the container under the radiator and unscrew its plug.
When it pours out, tighten the cap. At this stage, the throttle assembly heating hose is disconnected.
Again fill above the MIN mark and below the MAX mark. Place the throttle body heating hose in place, tighten the clamp and check the steam outlet pipe for leaks.

In this way you can drain antifreeze on a Priora with 16 valves. But on the Priora there are 8 valves with air conditioning, the work is complicated by the fact that there is no drain plug. The liquid should be drained from the lower radiator pipe, and after the procedure, put it in place.

It is recommended to clean the system after each replacement. If antifreeze is changed to antifreeze (or in the reverse order), it is necessary to clean it. For this you need:

plastic funnel with hose;
15 liters of distilled water (calculation made for Priora);
a small brush that fits into the neck of a five-liter bottle;
a packet of citric acid.

If the waste liquid is not cloudy, then distilled water will be sufficient. In other cases, the addition of citric acid is necessary. Remember that over time it becomes discolored, and contaminated waste fluid is manifested in cloudiness, not discoloration.

Cleaning occurs immediately after removing the air tubes in the system. Let water flow through the system through the open pipe, and clean the expansion tank separately - using a brush. Often after this, any cracks and damage to its body are visible. After completing the cleaning, you can fill the system with coolant.

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.

Sequence of actions - how to drain antifreeze

There is one important rule - replacing antifreeze on a VAZ 2110 should only be done when the engine is cool.

You should also be careful when handling this liquid as it is toxic. When you start the engine, make sure that the expansion tank cap is closed.

When you start the engine, make sure that the expansion tank cap is closed.

The procedure for performing an operation such as replacing the coolant is as follows. You should park the car on a level, level surface. If the site is located on a slope, make sure that the rear of the machine is lower than the front. Disconnect the wire from the negative terminal of the battery. The ignition module must be removed along with the bracket - this will allow you to gain access to the drain plug located on the engine cylinder block.

Further actions must be performed in the following sequence:

The expansion tank plug is removed,
A container of the appropriate size is installed under the engine and the plug is unscrewed. Here, in fact, is the answer to the question of how to drain antifreeze. After draining, you will need to wipe any traces of it from the cylinder block,
the plugs need to be screwed back into the radiator and into the cylinder block

If antifreeze is replaced on engines equipped with an injection system, then it will be necessary to loosen the clamp and also disconnect the coolant supply hose from the throttle pipe (heating fitting). The answer to the question of how to change antifreeze on carburetor engines includes slightly different manipulations. So, you will need to disconnect the hose from the carburetor heating fitting. This will allow air to escape from the cooling system as it fills. If you skip this point, the air accumulated in the system will not allow the system to fill to the required volume.

It is necessary to pour antifreeze into the system until the antifreeze level reaches the required level. This mark is located near the expansion tank fastening belt (at its upper edge). After this, you should tighten the tank cap. The expansion tank plug must be screwed in very tightly, because when the engine is running this unit will be under pressure. A not completely closed plug in this case can lead to such a nuisance as antifreeze leaks. The hose is connected to the carburetor or throttle pipe heating fitting (depending on which engine model we are talking about). By the way, replacing the timing belt also directly depends on this fact.

Next, the ignition module is installed in place, and the negative battery terminal is also connected back. Then you need to warm up the engine until it reaches operating temperature, that is, until the fan turns on. The engine stops, after which you again need to check the antifreeze - the actual fluid level. If necessary, add antifreeze to the top mark.

Replacing a heater radiator, as well as replacing antifreeze, requires compliance with a number of specific requirements. So, you will need to monitor the temperature of the liquid using the indicator. If the needle moves to the red zone and the fan does not turn on at this time, you need to connect the heater and check the air passing through it. If the air is heated, this indicates a fan malfunction. Cold air indicates that there is an air lock in the system. The engine must be turned off and then the expansion tank cap must be unscrewed (when the engine has cooled down). This will allow you to remove the blockage from the air.

Replacing antifreeze - video

A faulty cooling system on a VAZ 2110 can cause far from pleasant situations. Nobody wants to find themselves on the side of the road with antifreeze boiling and abundantly steaming from under the hood. But in order to avoid this kind of consequences, much is not required from the motorist. Do you want to know how to guarantee reliable operation of your iron horse?

Monitoring the condition of the cooling system of the VAZ 2110 (2112) is not so difficult. There is no point in visiting a service station for this. How do you like the idea of becoming a qualified technician in the field of repair and maintenance of your own car? And it's really not that difficult to learn.

Imagine, while someone learns from other people’s mistakes and bitter experiences, you will accumulate a valuable store of knowledge on the topic of the operation of the cooling system of the VAZ 2110 (2112) by reading the Internet. By spending a measly quarter of an hour reading an article, you can get much more information than in years of driving a 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.

Operating procedure

Draining old coolant

If the replacement is made on a lift or inspection pit, it is necessary to remove the engine protection, if any. When replacing without a pit, you don’t have to remove the protection, but then old antifreeze will get on the protection. There is nothing dangerous about this, but for a few days after the replacement, you may smell antifreeze until it evaporates. We place a drain container under the lower right side of the radiator, if conditions permit.

If you are not changing it in an equipped place and you do not need the old antifreeze, you can simply dump it on the ground. Many people advise initially opening the cap of the expansion tank, then unscrewing the plug at the bottom of the radiator to drain, but in this case old antifreeze under high pressure, especially if the engine has not completely cooled down, will flow out of the radiator. It is safer and more convenient to first unscrew the cap (plastic wing) of the radiator, the old antifreeze will flow in a thin stream, then carefully unscrew the cap of the expansion tank, thereby, due to the tightness in the cooling system, you will be able to regulate the antifreeze drain pressure.

After draining the antifreeze from the radiator, we need to drain the liquid from the engine cylinder block. The peculiarity of draining antifreeze on a VAZ 2110 from the cylinder block is that the plug on the block is closed by the ignition coil (on a 16-valve injection engine). To do this, we need to dismantle it, use a 17mm wrench to unscrew the bottom bolt of the coil bracket, use a 13mm wrench to unscrew the side and central bolts securing the bracket and move the coil to the side. Using a 13 key, unscrew the drain plug from the cylinder block. To more completely remove old antifreeze, you can connect an air compressor and apply air pressure through the filler neck of the expansion tank.

We tighten the plug of the cylinder block and the plug on the radiator (the plug on the radiator is plastic with a rubber gasket, it can be tightened by hand without unnecessary force; for reliability, you can coat the threads of the plug with sealant). We put back the ignition coil.

Filling with new coolant

Before adding new antifreeze to the VAZ 2110, it is necessary to disconnect the heating hose to the throttle valve (for an injection engine), or the hose from the carburetor heating fitting (on a carburetor engine), so that excess air can escape from the cooling system. Fill in new antifreeze to the level of the upper part of the fastening of the rubber belt of the expansion tank. We connect the hoses to the throttle valve or carburetor, depending on the model. Close the expansion tank cap tightly. Open the heater tap in the cabin to the hot position.

Filling antifreeze into a VAZ 2110

We start the engine. Immediately after starting the engine on a VAZ 2110, you need to pay attention to the level of antifreeze in the expansion tank; it may immediately drop, this may mean that the water pump has pumped coolant into the system. We turn off the engine, top up the level and start again. We warm up the car. During warm-up, we check for leaks in the engine compartment, in places where hoses and plugs were removed. We monitor the engine temperature.

When the operating temperature reaches 90 degrees, turn on the heater; if it heats with warm air, turn it off and wait for the engine cooling fan to turn on. When you turn on the fan, wait for it to turn off, turn off the engine, wait 10 minutes for the engine to cool down a little, unscrew the cap of the expansion tank, check the coolant level, and add if necessary.

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.

Preparing for replacement

Replacing antifreeze with your own hands begins as usual with choosing a tool:

Heads “10” and “13” with ratchet and extension
Phillips screwdriver
If you have an engine from the 2111 model, then you need to remove the ignition module using keys “13” and “17”
Empty container (bucket) for draining liquid
Rags

What to consider

So:

When starting to replace the fluid in your car’s engine, just keep the engine cool and the temperature of the VAZ 2110 16 valve coolant can reach 100 degrees, otherwise you will definitely get burned and scalded
Coolant (except water of course) is a chemical substance (very poisonous), it can harm your body and the environment, so do not taste it, do not inhale the fumes, do not get it into your eyes or skin
It is recommended to change antifreeze slowly and wear rubber gloves.
Do not pour antifreeze onto the ground, protect the environment
If you have topped up antifreeze, do not start the car until you have screwed the expansion tank cap back into place.

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.

Reasons for replacement

If we talk about the service life of antifreeze on a VAZ 2110, then it is within 150 thousand kilometers, and it is advisable not to exceed this mileage. Although in practice it happens that replacement or the need to partially change the coolant arises long before the speedometer shows so many kilometers.

Have you noticed that the color of the antifreeze in the expansion tank has changed and has become rusty;
You notice an oil film on the surface of the tank;
Your VAZ 2110 often boils, although there are no special prerequisites for this. You need to remember that the VAZ 2110 is still a fast car, and it doesn’t like driving very slowly; it sometimes causes the coolant to boil. This may be due to the cooling fan not running at low speed. It is also possible that unusable antifreeze is boiling and needs replacement;

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.

Replacing antifreeze antifreeze on a VAZ-2112 16 valves: photo, video

Replacing the coolant on a 16-valve VAZ-2112 is quite easy and simple. This does not require special knowledge. It is worth noting that the choice of coolant must be taken seriously, since using a liquid that has exhausted its service life can not only damage the power unit, but also lead to a major overhaul of the engine.

Video about completely replacing the coolant on a VAZ-2112:

Video materials will tell you about the process of replacing the coolant, the stages, and give tips and recommendations.

The process of replacing coolant on a VAZ-2112

Before proceeding directly to the replacement process, it is necessary to select the appropriate tools. So, to complete the process you will need:

Ratchet with 13mm head.
The key is 17.
Key for 10.
Container for liquid.
Funnel for the bay.

When the tools have been selected, you can proceed directly to the process. It is worth noting that replacing the coolant is carried out when the car has cooled down, so it is best to let it cool down after a trip for about an hour, depending on the ambient temperature. So, let's look directly at the replacement process itself:

Having placed the car on a pit or a lift, using a 10mm wrench we dismantle the engine protection.
Unscrew the cap of the expansion tank.
Unscrew the expansion tank cap. The photo shows the editor's car, this is what the coolant tank looks like, it's still original, the car is from 2003, the mileage is 170,000 km
Unscrew the drain plug on the cylinder block.
It is located in the front, near the plug. To remove the plug, use a 13mm socket. To drain most of the liquid, unscrew the drain plug on the cylinder block
At the bottom of the radiator there is a coolant drain plug that needs to be unscrewed.
Don’t forget to place a container so that the liquid does not spill on the floor or into a hole. To completely drain the liquid, remove the cap from the radiator.
When all the liquid has drained, tighten all the plugs and pour new liquid into the system.
This is how antifreeze will flow from the engine
We remove airiness.
To do this, you need to squeeze the pipe several times so that the air escapes through the expansion tank. Fill in new fluid through the knob
Next, it’s worth driving a few kilometers and adding fluid that has gone into the system.

If necessary, you can change the thermostat and pipe clamps that are worn out.

Antifreeze or antifreeze

Antifreeze versus antifreeze - which is better?

Motorists often face the question of what is better antifreeze or antifreeze? Of course, in terms of technical and physico-chemical characteristics, antifreeze is inferior to antifreeze. The second one is better to use in winter, since it has many additives that have a lower freezing point and a higher boiling point.

Of course, the manufacturer recommends using antifreeze, since it is designed specifically for cars of the VAZ family. Of course, price plays a very important role, where antifreeze loses to its competitor. Therefore, in the end, we can say that both types of coolant can be used for VAZ.

Replacing coolant on a VAZ-2112 with a 16-valve engine is quite easy and does not require much difficulty. Thus, the entire process may take about 40 minutes. For cars of this type, both antifreeze and antifreeze are suitable.

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.

Recommendations for selection

For VAZ 2110-12 models, you can find 2 types of expansion tanks on sale:

old model with two necks: the coolant level sensor is screwed into the first, and the second is closed with a plug with a release valve;
a new model with one neck (without sensor) and a body convex on the sides.

If your car has a sensor in an expansion tank, then you need to select an old-style product. Accordingly, versions without a sensor will require a new reservoir design.

The reservoir for models 2114-15 has a wider shape and a versatile arrangement of fittings

When purchasing an expansion tank for any series of cars of the “tenth” family, pay attention to the following points:

the plastic of a quality product should be light and half transparent;
cracks in the corners or near the fittings are unacceptable;
the plastic should not be “oaky” or have dark impurities visible to the naked eye;
look on the body for an imprint of the manufacturer's trademark and catalog number (21083–1311014 for VAZ 2114).

For all modifications “ten”, “fourteen” and “fifteen” a small tuning is available - installation of an expansion tank from the cooling system of a Lada Priora car. Why and how this is implemented will be discussed below.

The reservoir of the Priora cooling system has a rectangular shape and 3 fittings on the front wall
