Checking the coolant level.
Checking and adding antifreeze.
You will need: coolant
, clean rag.
The expansion tank is installed in the left rear part of the engine compartment.
Attention!
Check the coolant level only when the engine is cold. Coolant is toxic, so take precautions when handling it.
1.Level
coolant in the expansion tank should be located at the upper edge of the tank fastening belt.
2. An emergency coolant level sensor is installed in the tank, which is triggered if the level drops below the permissible limit. At the same time, it turns on the low coolant level indicator located on the on-board control system display unit on the instrument panel.
3.For topping up
fluid, unscrew the cap of the expansion tank.
Checking the level and adding fluid to the washer reservoir
You will need: in summer - clean water, in winter - anti-freezing liquid.
The windshield washer reservoir is located in the left front part of the engine compartment.
Attention!
Observe precautions when working with antifreeze fluid. Always ensure that the level in the washer reservoir is sufficient; do not wait for the minimum fluid level sensor in the reservoir to respond. Do not turn on the washer if the fluid level drops below the pump intake hole inside the reservoir - the washer pump motor may fail.
1.Unscrew the washer reservoir cap.
2.Remove the cup and check the mesh. If it is dirty, rinse the mesh with water and replace the cup.
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
To drain most of the fluid, unscrew the drain plug on the cylinder block.
To completely drain the liquid, remove the cap from the radiator.
This is how antifreeze will flow from the engine
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.
Cooling system
To understand how to deal with the problem, you need to know how the cooling system in a car works.
Antifreeze is a chemical-based liquid that prevents the engine from heating up in the summer and prevents the radiator and block from freezing in the winter. It turns out that antifreeze is designed to protect the engine from its critical temperature.
The special composition of this liquid ensures that it can boil at a higher temperature than ordinary water . Depending on the type of motor and brand of liquid, the boiling point is on average 110 degrees. There are also mixtures that can boil at a temperature of 200 degrees.
If the cooling system of the car is working correctly, then the antifreeze does not boil and is not squeezed out of the tank. This also ensures normal engine operation. At the same time, antifreeze does not destroy metal and plastic, and therefore it can be considered safe for cars.
Cooling system VAZ 2110 for 8 and 16 valves
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?
The principle of operation of the cooling system on a VAZ
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.
The principle of operation of the cooling system on VAZ 2110 (2112) cars
The idea of working the cooling circuit of an internal combustion engine is extremely simple and similar for most car brands. On the VAZ 2110, the injector cooling system is somewhat different from the carburetor one. But, in general, the differences are not so critical that each of these systems should be considered separately.
To understand how the cooling system works on your VAZ 2110 car, it’s worth starting with the fact that engine operation at a temperature range of 80 to 90 degrees is considered normal. Celsius. Thus, first of all, it is important to quickly warm up to the operating mode and further maintain the temperature of the internal combustion engine in a given range. More details below.
To accomplish this task, the cooling system of the VAZ 2112 (2110) consists of the following key components, such as:
- pump pump, which carries out forced circulation of coolant in the system;
- a VAZ 2110 coolant radiator and an electric fan that provides forced air flow and cooling of the radiator;
- expansion tank, which is also an important component of the proper operation of the VAZ 2110 cooling system;
- a resistive temperature sensor that detects the temperature of the coolant and turns on the fan;
- two-valve thermostat that controls the operation of the small and large cooling circuits. The VAZ 2110 injector cooling system is fundamentally different in its thermostat design.
Main components of VAZ 2110 cooling system
The coolant initially circulates through a small circuit, bypassing the radiator to more quickly warm up the internal combustion engine and bring it into operating mode.
As it warms up, the cooling system of the 2112 VAZ, thanks to the pump, switches to a large cooling circuit.
Now the pump pump drives coolant from the engine to the radiator, and the temperature sensor determines when it is necessary to provide more intensive cooling and controls the operation of the fan.
Regardless of the degree of engine warm-up in the system and the position of the thermostat valves, the heating circuit with a small radiator and fan also operates separately. The temperature regime of the interior in VAZ 2110-2112 cars is set by the position of the air damper; coolant constantly passes through the heating circuit.
Cooling system of the VAZ 2110 and its typical malfunctions
Despite the fact that there may indeed be many possible problems with cooling the internal combustion engine on a VAZ 2110, they are all related to the reliability of its main components. If you know how the cooling system works on VAZ 2110 cars and what it consists of, it will be very easy to find and diagnose the problem. We'll tell you what exactly you can find below.
Typical problems are:
- coolant leaks and insufficient level;
- there is no pressure in the cooling system due to failure of the pump pump;
- the cooling fan does not work correctly or does not turn on due to the failure of the temperature sensor;
- The thermostat does not work, as a result of which coolant cannot circulate through the large cooling circuit, or constantly circulates through it. In the latter case, the engine does not warm up well;
- The radiator fins are dirty.
Condition of the radiator after 120t. km run
Do not forget to regularly monitor the level of coolant in the expansion tank under the hood of the car and the condition of the timing belt. Listen carefully to extraneous sounds when the pump pump is running; it is recommended to change the coolant to a new one every 75 thousand km. mileage
Use the self-diagnosis mode to check for temperature errors. Don't forget to clean the radiator and monitor its temperature when the engine is running (it should be hot). Take care of your iron friend and he, in turn, will not be capricious on the road.
Antifreeze, water or antifreeze. Why is coolant needed on the VAZ 2110
Of course, if there is no coolant, the cooling will not work. It's hard to argue with this. Much more interesting is what can be poured into the expansion tank and how often the coolant should be changed.
Expansion tank VAZ 2110
The most common water is very popular among motorists as a coolant, characterized by high heat transfer characteristics. Be sure to keep in mind that you can only use distillate. That is, water purified from alkaline impurities that corrode the aluminum pipeline.
The main problem with water is that it freezes at low temperatures. If we want the cooling system of the VAZ 2112 to survive frosts and not “break”, before winter we should still drain the water and fill the system with Antifreeze.
Antifreeze or Antifreeze
Motorists often ask how Tosol differs from antifreeze. The question is somewhat incorrect, because the definition of antifreeze simply generalizes all kinds of liquids that do not freeze at low temperatures. And Tosol is a domestic brand of coolant for cars.
You can buy Antifreeze with a freezing temperature of -40 and -65 degrees. Celsius. In the first case, it will be a blue liquid (Tosol-40), and in the second - red (Tosol-65). The color is determined by the dye and is needed only to make it easier to distinguish between different brands of coolant and its leakage under the hood of the car.

Reasons for leaks
Coolant leaks around the expansion tank cap.
There are many reasons why antifreeze can leak from the VAZ-2110 tank. If the car is operated correctly, then usually a leak can occur due to wear and tear on system elements.
- The system has rubber pipes, which, despite its density and resistance to aggressive environments, can last a long time, but in the process it wears out and ages.
- In this case, cracks are formed, which lead to air entering the system.
- Also, some of the antifreeze may be lost through cracks, and therefore this leads to overheating of the engine.
- At high temperatures, high pressure arises in the system, which pushes the liquid out through the plug on the tank.
Plugs or tanks
If the expansion tank on a VAZ-2110 was replaced, then the cause of the antifreeze leak may be a poor-quality tank or plug, of which you can find many on the modern market. If there are chips on the thread, this will not ensure tightness, so the antifreeze will leak out.
The problem may be in the tank itself. When its walls are thin, they can burst when expanding. In this case, antifreeze leakage will also occur.
A crack in the tank made of low-quality plastic.
Thermostat and low amount of antifreeze
These may also be the reasons why the engine will overheat, antifreeze will boil and be squeezed out of the system under pressure.
A small amount of antifreeze will not be able to provide normal cooling to the engine, and therefore the temperature will constantly rise. a malfunction of the thermostat can cause the permissible temperature to be exceeded .
Why is antifreeze needed on the VAZ-2110?
Without antifreeze, the cooling system cannot function, which is why its volume must be constantly monitored. It is appropriate to use distilled water as antifreeze, and all thanks to its high heat transfer properties. Ordinary water will not work - it contains too many alkaline impurities that can quickly corrode and destroy an aluminum pipeline.
Experts have their own professional opinion about the coolant - it is unacceptable to fill it with water at low outside temperatures. That is, in winter, water is not an option for the cooling system. What are the consequences of persistence in filling water in winter? The mechanism will simply “break”. Therefore, it is better to turn to a special substance called antifreeze.
Antifreeze is not in danger of freezing even at very low temperatures outside the window - it can withstand up to minus 65 degrees. If the liquid is purchased frozen at minus 40 degrees, it turns blue and is called “antifreeze-40”; at minus 65 the substance is sold under the name “antifreeze-65”.
Diagnostics
Since antifreeze can evaporate quickly, especially on a hot engine, this makes it difficult to identify the location of its leak . If a large amount of antifreeze leaks out, it is easier to spot the leak.
- When antifreeze leaks in the cabin, this indicates a malfunction of the stove. It needs to be changed. Faucets can also leak.
- When antifreeze enters the combustion chamber, it will cause water to appear on the exhaust pipe. The smoke will turn black . This will indicate that the gasket in the block is faulty.
- It is worth checking the tightness of the pipes. They need to be examined carefully, especially in the area of the tank. Often in a VAZ-2110 antifreeze can leak from the bottom of the tank where the pipe is attached.
All these moments can be accompanied by overheating of the engine and boiling of the liquid in the cooling system. Its temperature can usually be determined using a sensor on the instrument panel.
Consequences
If such problems with the cooling system are not corrected in a timely manner, this can lead to serious consequences. When antifreeze simply leaks out of the system, this will cause the engine to overheat and fail.
First of all, when the engine overheats, the gasket in the block will suffer. At high temperatures it can lose its properties and burn out. In this case, antifreeze will get into the oil, reducing and worsening its properties. This will affect the lubrication of parts rubbing against each other. They will quickly fail.
When the liquid is squeezed out, this will not affect the quality of the oil. But other systems and elements may react to high engine temperatures. They may simply become deformed. The engine will lose power and require expensive repairs .
How much antifreeze should be poured
The VAZ 2110 is filled with coolant as soon as the existing antifreeze begins to lose its properties. You can tell this by the color change.
When you change the fluid, do not think that five or six liters will be enough, since the antifreeze level has reached its maximum level in the expansion tank. But that's not true.
It is necessary to wait until all the antifreeze is distributed throughout the system. This may take a few minutes.
When adding coolant, make sure that it is not higher than the maximum and not lower than the minimum level. If there is not enough antifreeze, the engine will overheat. Also remember that when heated, liquid expands and therefore increases in volume. So it’s also not worth pouring antifreeze above the MAX mark.
What needs to be done after adding antifreeze:
- Close the tank lid.
- Start the engine. Let it run until the cooling fan comes on.
- Turn off the engine and wait for it to cool down.
- Open the expansion tank cap again.
- If necessary, add a little more antifreeze.
Now you know how many liters of coolant need to be poured into the expansion tank for normal operation of the VAZ 2110. Ideally, the volume of antifreeze should be slightly less than eight liters. This must be taken into account when replacing antifreeze. And don’t forget that it is he who will help extend the life of your “iron horse” so that it will delight you with its work for many years to come.
How to solve problems?
The problem can be solved by periodically inspecting the cooling system and identifying its weak points.
In order to prevent antifreeze from leaking on the VAZ-2110, you must constantly and regularly inspect the engine compartment in order to notice a leak of antifreeze in time. Also, do not use used parts, such as a lid or tank. You also need to buy new hoses.
We also need to stop using cheap antifreeze. It can negatively affect the density of rubber and plastic, which will lead to leakage and depressurization of the system.
