Self-replacement of the Lada Kalina thermostat step-by-step instructions

The thermostat is, of course, one of the most important components of the engine cooling system. Thanks to this small and simple device, the engine is always in good shape, and the correct coolant temperature is maintained in its cooling system.

For those who don’t know what a thermostat is and how it works, a little theory...

The main function of the thermostat is to control the coolant temperature and prevent engine overheating. The temperature is regulated by a valve installed in the cooling system; it automatically opens when the temperature is higher than necessary and, vice versa, closes if the coolant is too cold. The second is necessary in order to reduce the engine warm-up time in cold weather. The coolant can move in a “small” or “large” circle. To warm up the engine faster, the thermostat closes the large circle and the coolant flows through the small circle; when the coolant temperature reaches 85 °C, the thermostat valve begins to open at 100 °C, it is fully open.

The thermostat operates solely under the influence of the laws of physics; it is completely mechanical. The opening of the valve occurs due to a solid heat-sensitive element, which melts when heated, opening the damper for the free movement of coolant in a large circle.

Characteristics of the Lada Kalina thermostat

The thermostat is an important engine cooling system; it occupies a place between the radiator and the cylinder block of the power unit. By design, this is a housing with an automatic valve, which, when the coolant is heated to a certain temperature, opens a large circulation circuit through the main cooling radiator. By closing the large circuit when the engine is cool, the car warms up much faster when circulating through the small circuit. The wear of its moving parts is reduced, overheating is eliminated, and the volume of harmful substances released into the environment is reduced.

A working thermostat allows you to warm up the engine to operating temperature, which for Kalina is 90-95 degrees. Over time, the valve wears out, and the heater maintains a temperature of no higher than 80 degrees. A working device helps the engine quickly warm up even in severe frost. Thanks to this device, the stove on Kalina is considered one of the warmest on VAZ cars. According to experts and car enthusiasts, the best price-quality ratio is the standard thermostat produced by DAAZ. It's all about a special screw, with which you can independently adjust the valve opening temperature. It is impossible not to take into account the reliability of factory products, which in this regard are superior to most analogues.

The same thermostats are used for 8- and 16-valve engines.

Engine cooling system "Kalina" on VAZ 2110

How does the Engine Cooling System (ECS) work on Lada Kalina?

What are the advantages of installing Kalina SOD on a VAZ 2110?

1. The engine warms up faster, and therefore the car becomes warmer earlier.
2. Lower pressure in the SOD, that is, the expansion tank on the VAZ 2110 will no longer burst.
3. There will be no need to frequently add coolant.

It is impossible to say exactly how much faster the VAZ 2110 engine with Kalina SOD will warm up. The indicators may be different due to the engine (16kl takes longer to warm up than 8kl), differences in temperature, humidity, thermostat (5 holes or 6 holes), SOD connection diagram, etc. .d.Approximately, you can focus on a 20% increase. Although some do not see the difference between the Kalina SOD and the VAZ 2110 SOD :) The Kalinovskaya SOD, in comparison with the VAZ 2110 SOD, has only one dubious drawback - the frequent inclusion of the fan in the absence of external airflow to the radiator (i.e., “traffic jam” mode). Although in most cases, no negative aspects of using Kalina SOD on the VAZ 2110 were identified.

What is needed to change the VAZ 2110 SOD to Kalina SOD?

Thermostat operating principle

The operation of a thermostat resembles the operation of a valve, only the opening and closing of the thermoelement occurs under the influence of temperature differences. The nominal operating temperature of a car engine is approximately 90°C, the temperature of full opening of the thermostat valve is 85°C. When the engine is cold started, the thermostat is in the closed position and opens completely when it reaches 85°C. On a cold engine, the coolant circulates in a small circle bypassing the cooling radiator; as soon as the temperature reaches operating temperature, the thermostat opens and the coolant begins to circulate in a large circle through the cooling radiator, thereby maintaining the operating temperature and preventing the engine from overheating.

Management

We bring to your attention detailed instructions for completely replacing the thermostat with a new one. Even if you don’t understand how to replace the thermostat on a viburnum, the video will help clarify the situation.

1. Disconnect the sensor from the air filter housing and remove the air filter. As a rule, it will take no more than ten minutes to dismantle it. This is done correctly like this:

• completely unscrew the 2 screws located on top, as well as the nut located on the side of the engine compartment. We recommend leaving these parts in one place so that later you don’t have to look for them separately on the market;
• remove the connector installed on the recirculation valve (it, in turn, is based on the filter housing);
• lift the valve up, and then, without disconnecting the tubes, move it all to the free side;
• by unplugging the plug from the air sensor, remove the air hose by loosening the clamp;
• Having slightly loosened and turned the air filter housing, it should come out.

2. Before carrying out direct disassembly . get rid of some of the coolant

3. Take a 8mm socket wrench and a screwdriver. Use it to loosen the clamps , and then remove the four hoses.

A well-pumped system will not allow liquid to spill in large quantities.

4. Take a 12mm wrench and remove the wire by unscrewing the top nut on the thermostat.

5. Now take the key for 13. There is a nut and a stud on the thermostat - you will find the first in the upper part of the housing, the second at the bottom. Try to remove the thermostat by gently loosening it.

Helpful advice: loosen the thermostat carefully, sometimes helping yourself with a screwdriver.

These actions must be performed because during operation, high temperatures literally “solder” the thermostat, causing the housing to stick. Help with a screwdriver will solve this problem.

6. Next, clean the seat from accumulated dirt (there will be a lot of it there). Don't leave the old gasket in place - get rid of it completely. Wipe the seating areas with a clean cloth. Using sealant, 1-1.5 mm of substance per seat, or use a paper gasket. The best option at the moment is sealant. If you have applied it, stop working for 5-10 minutes. During this time, the sealant needs to crystallize. In the case of a paper gasket, work can be carried out immediately.

7. Installation of a new thermostat is carried out in the exact opposite order of removal. It is important not to forget to replace the temperature sensor from the old thermostat. It is also important to connect the ground wire. This is done by screwing the ground wire onto the top stud.

8. After all hoses are reconnected, add coolant to the system . Its quantity can be selected based on how much liquid you drained during disassembly of the old faulty device. To accomplish this task, the method of removing air pockets is used.

In test mode, start the engine. While it is idling, make sure that all hose attachment points are not leaking . If such a problem occurs, tighten the loose clamps.

Replacing the thermostat

On the automotive spare parts market you can find a large number of thermostats from various manufacturers; their cost varies from 400 to 700 rubles. When choosing, it is better to stick to original AvtoVAZ spare parts. The catalog number for the standard thermostat on Kalina is 1118-1306010. Of the analogues, “Luzar” and “Pramo” have proven themselves well, but the first is often counterfeited, and the second has poor quality - the service life is on average about a year. The original device, which is installed from the factory, can last more than three years. Replacing a thermostat on Kalina with 8 valves or 16 is estimated at no more than 800 rubles, including removing air from the system. To avoid paying twice, you can change the part yourself. Just before this, you should check the device for functionality using the described methods.

What tools will you need?

To operate, you will need a working thermostat and a suitable container for draining the coolant from the SOD - a regular five-liter plastic bottle. The differences between replacements on an 8- and 16-valve engine are insignificant. On the latter, you will need to additionally remove the starter so as not to accidentally fill it with antifreeze. The rest of the procedure is similar.

To remove the assembly, you will need two socket wrenches, 13 mm and 12 mm, since Kalina uses nuts of different sizes.

To seal the seat, you will need a silicone sealant gasket. To remove the clamps, use a shaped screwdriver. The procedure lasts on average an hour and a half.

Replacement instructions

The replacement process is not complicated and can be done independently if you follow the instructions. First you need to disconnect the wire plug from the sensor on the air filter and remove it. It will take a few minutes to properly dismantle the filter:

• the two upper screws are completely unscrewed together with the nut from the power unit side;
• there is a recirculation valve on the filter housing; it must also be removed;
• lift the valve up and, without disconnecting the hoses, move it to the side;
• unplug the terminal from the air sensor and, loosening the clamps, disconnect the air pipe;
• After shaking the filter from side to side, turn its housing and try to pull it out.

Further procedure:

1. Drain the coolant from the system.
2. Using an 8 mm wrench or a shaped screwdriver, loosen all the clamps of all connecting hoses, then disconnect them.
3. Unscrew the 12 mm nut on the thermostat and remove the wire.
4. Using a 13 mm wrench, unscrew the fastening nut at the top and bottom of the thermostat on the studs, then try to remove the device by slightly loosening it. You don't need to make a lot of effort for this. Keep in mind that the thermostat operates at high temperatures, due to which the housing literally “sticks” to the seat.
5. Clean the seat from dirt and remove the old sealing gasket. Then wipe the treated area with a clean rag, apply a thin layer of silicone cover and leave for 5-10 minutes.
6. The new thermostat is installed in the reverse order. You should definitely replace the temperature sensor by removing it from the old device, and do not forget to connect the ground wire. To do this, it is fixed with a nut on the upper stud.
7. Connect all hoses and fill the system with coolant to the maximum level.

After completing these steps, you need to start the engine and inspect all the places that were disconnected. You can make sure there are no leaks by lightly pressing all the hoses several times. The liquid level in the tank will drop, then you need to add antifreeze to the middle mark and screw the cap tightly.

Control check

After completing the work to replace the part, the problem with overheating or long warm-up should disappear. All that remains is to check the correct functioning of the thermostat. To do this, periodically you need to pay attention to the temperature indicator arrow. If it does not rise above 90-95 degrees, then the system is working normally. When replacing, you should take into account the specific temperature conditions of the products - it can be either lower or higher than average.

When carrying out vehicle maintenance, the thermostat must also be inspected, despite the fact that this is not included in the regulations. Timely replacement of a faulty device will prevent premature wear of engine parts and prevent overheating of the power plant. A small device with one valve can affect the functioning of the entire heat removal system from the internal combustion engine.

Thermostat malfunctions

The design of the thermostat consists of a housing with pipes and a sensitive element with a valve, which actually shuts off the pipeline. The housing itself fails extremely rarely, and only due to mechanical damage.

Most often the sensitive element breaks. It is a sealed cylinder filled with a wax-based solid. The cylinder contains a piston with a rod. When heated, the substance melts and expands, pushing the piston. The latter extends and closes the valve.

The most common reasons for thermostat failure are:

• deposits of products of corrosion processes on the moving parts of the sensitive element;
• dirt, scale or foreign objects entering the thermostat housing;
• poor quality coolant;
• malfunction of the water pump (pump).

One symptom of a faulty thermostat is an overheating engine. It indicates that the coolant (coolant) moves in a small circle without passing through the radiator. It can also happen the other way around, when the liquid moves constantly in a large circle. In this case, the engine will take a very long time to warm up.

How to understand that it’s time to change it

Replacing the thermostat on Kalina 8 valves is necessary in the following situations:

• the engine is constantly exposed to excessively high thermal loads, the temperature increases. This may lead to new unforeseen troubles;
• engine overheating is constant, but not reaching a critical level;
• if the coolant temperature began to rise for unknown reasons, etc.

It is important to closely monitor changes and monitor dynamics. If a spike occurs, it is recommended to immediately seek professional help. Traveling with a broken vehicle can end in disaster. If your car constantly overheats, but this does not cause a breakdown, you should think about timely replacement of parts.

You can do the process yourself or visit a service station. In order to do the work yourself, it is recommended to follow simple instructions.

Symptoms and consequences

Like any other mechanism, the thermostat can break down instantly. If this happens, the main thing is to detect the breakdown in time. Most often, a faulty mechanism can be detected when:

• increasing the amount of time required to fully warm up the power unit;
• the presence of elevated temperature in the power unit or even overheating.

The worst consequence of driving a car with a faulty thermostat is an overheated engine. There is no need to remind you once again about the consequences that overheating can cause. Therefore, we suggest that you familiarize yourself with the issue of replacing a problematic thermostat on a Lada Kalina car.

In what cases is it necessary to check pressure?

The pressure in the fuel rail should be checked if certain problems arise with the fuel system. The main signs of a malfunction include the following factors:

• Increased fuel consumption;
• Unstable engine operation at idle speed;
• Engine tripping occurs;
• An increased CO content is observed in the exhaust gases.

Sometimes the problems listed above may indicate a problem with the electronic control unit. Therefore, before starting to check the pressure in the fuel rail, the driver is recommended to make sure that the ECU is working properly.

Verification methods

There are two ways to determine the functionality of the thermostat. The first method involves checking without dismantling. To do this, you need to start a cold engine, warm it up to operating temperature (about 90 degrees), and touch the lower radiator hose.

A cold lower pipe at this temperature indicates that for some reason the thermostat did not open. If it is hot, the thermostat operates normally.

For a more accurate check, you will need to remove the thermostat cover with the sensitive element. Place it in a metal container with clean cold water and place it on the stove to warm up. When the water temperature reaches 85-90 degrees, the element should operate, pushing the valve stem forward. If this does not happen, the thermostat is faulty.

Installation of a thermostat from Grant

Before installing a new temperature-maintaining device, the studs from the camshaft of “classic” VAZ models are screwed in. All heels have triangular cutouts at one end. This is how manufacturers mark the end that screws into the engine block. Sealant is applied to the junction of the thermostat and the engine and a gasket is installed. The following installation steps:

1. The thermostat is mounted on studs and screwed with nuts.
2. A pipe is removed from the lower outlet of the stove in order to insert a tee into it, another outlet of which will be connected by a pipe to the expansion tank.
3. After completing this procedure, the pipe is put in place, connecting the thermostat and the stove. A pipe leading to the expansion tank is put on the outlet of the tee and secured with a clamp. Air will be removed from the cooling system through it.
4. A Grant hose is installed, running from the lower radiator pipe to the thermostat. It fits almost perfectly, so there is no need to lengthen or shorten anything.
5. All that remains is to secure all the pipes with clamps, install the air filter, battery and add antifreeze.

If everything is done correctly, the engine will stop heating and will not raise the temperature needle close to critical values. And the car interior will be warm, even in the coldest weather.

What is a thermostat?

A thermostat is a component of a vehicle's cooling system that maintains the recommended coolant temperature.

The main component is the valve.

Depending on the position of this valve, the liquid will flow in a large or small circle. With the help of a thermostat, the engine will not overheat as a result of constant operation over a long period of time.

In the case of winter cold, the device significantly saves the fuel needed to operate the engine. Plus, the time spent warming up the vehicle engine to the optimal temperature will be reduced. On a car such as the Lada Kalina, replacing the thermostat is necessary if, in the temperature range of +85...+100 degrees Celsius, its valve does not open.

The principle of operation is to comply with the normal laws of physics. The solid heat-sensitive element melts during the heating process, due to which the damper opens independently. The degree of openness depends, first of all, on how much the heat-sensitive element has melted. As the device operates, it determines the further path of coolant flow.

Let us remember that it can flow either in a small or in a large circle.

Replacing coolant temperature sensors on Kalina

Welcome! Coolant temperature sensors - if we talk specifically about the Lada Kalina car, then there are only two sensor data in it, one goes to the controller (This is the brain, to put it simply), and the other to the device, that is, one sensor shows what the temperature of the coolant in the car is and displays this is all for the device, and another one (which gives readings to the controller) turns on the cooling system fan when the car is boiling, and also regulates the fuel-air mixture (Simply put, when the car is cold, thanks to this sensor it will warm up faster, because the sensor richens the mixture and the temperature immediately rises), both of these sensors are important and if they fail they will cause quite a lot of trouble, especially for the sensor that gives readings to the device, if it stops working, then you simply will not know the temperature of the coolant and in connection with which you can overheat the engine.

Note! To replace both sensors (you will most likely only replace one), stock up on: Wrenches, as well as sockets and a wrench for them, you will also need a multi-meter (This is in case you want to check the functionality of the old sensor ) and a screwdriver!

• Replacing coolant temperature sensors
• Additional video clip

Where are the coolant temperature sensors located? We would like to immediately note one very important fact, just below we have posted a photo in which we have already indicated with arrows the location of both sensors, but the photo shows a VAZ 2110 car, and you have a Lada Kalina, in general there is not much difference in the engines and these sensors are also on them are located practically in the same places, we just wanted to warn you so that you are not too surprised when you look at your engine, because they may differ slightly, but in general, as already said, they are almost the same, in general the sensor that measures coolant temperature and gives it to the controller, screwed into the thermostat and indicated by a red arrow, the second sensor that gives readings to the device is already indicated by a green arrow, but since it is not visible in the photo, we also indicated with a blue arrow the wire that is connected to this sensor .

When should coolant temperature sensors be replaced? The sensors themselves should last quite a long time, but they don’t always come across high-quality ones, and even literally after a month new sensors already fail, it’s not difficult to understand this, especially if it’s a sensor that goes to the device (the gauge will immediately stop showing the coolant temperature, the arrow will just will lie, for clarity this indicator is indicated by an arrow), but with the sensor that goes to the controller it’s a little more complicated and you won’t even immediately understand that it’s time to change it, well, let’s move on to the symptoms, firstly, if the sensor going to the controller comes in unusable, then the car will consume more gasoline (This is due to the fact that the mixture will always be rich) and the cooling fan will not work when the engine overheats, if you notice all this in your car, then immediately change the sensor to a new one or simply remove the old one and check it (we explained in this article a little lower how both sensors are checked, so read it and you will understand everything as you read).

Signs of a bad thermostat

There are several characteristic signs of a thermostat malfunction on a Lada Kalina car:

• The car engine does not warm up to operating temperature;
• The engine quickly heats up and boils;

Let's look at each of the reasons in more detail.

Cold engine

If the thermostat is stuck in the open position, the engine will not be able to heat up to operating temperature due to the constant circulation of coolant in a large circle through the cooling radiator. The reasons for a stuck thermostat can be long-term use of coolant without replacing it and flushing the system. The thermostat body is made of aluminum, and the thermoelement is made of metal; with long-term use of coolant, traces of corrosion appear on the thermoelement, which leads to improper operation of the thermostat and its failure.

Hot engine

When the engine overheats, the reasons are the same as when it is not heated, only the thermostat gets stuck in the closed position. Also, jamming of the thermostat in the closed position can be confused with the breakage of the petals on the pump, which leads to the impossibility of coolant circulation along the circuit.

Filling with new coolant Kalina

The installation of new pipes is complete. Now the most interesting part is that you need to fill in new antifreeze . Don't forget to tighten the bolts from the drain holes back. I use Felix Green G11. To avoid the occurrence of a large number of air pockets, before filling in the coolant, I removed one hose from the throttle heating - the highest point of the cooling system. During the process of filling the system, air could be heard escaping. Out of 10 kg of antifreeze, about 2 liters remain in the canister.

I filled it up to the MAX mark on the expansion tank and put the hose from the throttle back in place. Now you can try to start the engine and see what happens. Before this, of course, you need to put in place the ignition module and the air filter along with the mass air flow sensor and the adsorber valve.

After the first start, the engine heated up to 120 degrees, but the radiator remained cold. I waited about 10 minutes until the engine cooled down and SLOWLY unscrewed the cap from the expansion tank, releasing the pressure, and then unscrewed it completely. At that moment I heard a gurgling sound - excess air was coming out. Some fluid has leaked into the system. I added new fluid to the reservoir and started the engine again. This time everything worked as it should - the radiator warmed up, the fan turned on, the stove was heating, the temperature stayed around 90º.

And on this positive note, the procedure for replacing the pipes on Kalina, as well as the thermostat and antifreeze, can be considered completed.

In the engine cooling system in a Lada Kalina car with an engine of 8 valves, as well as 16 valves, the thermostat plays a significant role, because it is a regulating link, thanks to which the operating temperature necessary for the normal implementation of the combustion process is maintained in the circuit. The main signs of failure of this part are:

• unit overheating;
• inability of the motor to reach its operating temperature.

How can you modify the heater?

The new models Lada Kalina 2 and Lada Granta use a cooling system operating scheme with parallel connection of the heater radiator. Because of this, the operating temperature is reduced to 85 degrees, which is slightly lower than on previous models of the VAZ family. Many car owners seriously believe that this temperature cannot be normal - there is increased fuel consumption, as well as a decrease in the service life of moving engine parts due to premature wear. But according to experts, there is no connection between the reduced operating temperature and engine life.

The cooling system of the Lada Kalina works more efficiently thanks to a single-circuit design. Such a modernization only benefited the engine; it made it possible to change the ignition timing, resulting in fuel savings. The inertia of the thermostat is also reduced. The downside was the mediocre heating of the cabin at sub-zero temperatures. The way out of the situation is to independently modify the thermostat. Modification involves two main methods:

• shorten the rod of the solid-state temperature-sensitive element;
• replace the thermocouple.

For cars with a cable gas pedal, a heated throttle assembly from the cooling system is used. In this case, an additional circulation circle is added.

Adjusting the thermocouple rod

Shortening the end of the thermosensitive element rod will allow you to adjust the operating temperature to 90-95 degrees. Trimming is carried out sequentially in increments of no more than one millimeter. The metal is soft, so the procedure must be carried out carefully. It is advisable to reinstall the thermostat after each millimeter cut and check how much the operating temperature rises while driving.

If the result does not meet expectations, you can adjust the rod further until the arrow on the instrument panel shows 95 degrees and the air in the cabin begins to warm up faster. The method is simple but effective. Among the disadvantages, there is a slight increase in wear of SOD parts due to operation at high temperatures. If you overdo it with shortening, you can ruin the device.

Replacing the temperature sensor

The thermocouple can be replaced entirely. The Wahler brand thermostat insert is suitable for Lada Kalina: 3017.87 D (at 87° C) or 3091.92 B (at 90° C). The thermoelement is replaced as an assembly with a spring, and the device will have to be cut with a hacksaw to remove the insert. A more convenient option is to buy a thermostat from BEHR - you don’t have to cut or adjust anything

You can also use analogues from Daewoo Nexia or Renault Logan cars. Logan's thermal insert requires adjustment.

If a LUZAR thermostat is installed on Grant, then replacing the temperature-sensitive element is not possible.

Judging by the reviews of car owners who have made such modifications, fuel consumption while warming up the engine has decreased slightly.

Throttle body heating

Another way to upgrade the heater is to create an additional throttle valve heating circuit. Some drivers are trying to prevent the unit from freezing in winter in this way. The method is clearly not for beginners. It consists of drilling a hole in the cover of the device and welding an additional fitting to it, through which heated antifreeze will be discharged. The thermostat mounting studs will also have to be lengthened. The process is labor-intensive and ultimately impractical. Freezing of the throttle assembly is the exception rather than the rule, so there is no point in carrying out such an upgrade.

Operating temperature of 8-valve

The normal operating temperature for eight-valve engines on Kalinas and Grants is exactly 90 ºC. But owners complain that sometimes it has difficulty reaching 80 degrees even in warm weather. The reason lies in the thermostat - it opens fully at a temperature of 85 degrees. Moreover, the permissible deviation from this value is very large - (85±8.3) ºС.

But the fuel mixture can only ignite normally if the engine temperature is about 90 degrees. This is the value stored in the electronic control unit. If the temperature is too low, the mixture becomes richer (the amount of gasoline increases). This is the main problem that occurs when the temperature drops. And in winter the heater works worse.

Your case

Temperature diagram. Normal operating temperature is at 90 on the instrument panel.

A stuck thermostat valve is a typical malfunction of the engine cooling system.

That is, the liquid that has not yet been heated is supplied to the cooling radiator and blown by a strong wind flow. Indeed, with an increase in air temperature, the problem will partly go away. That’s why they used to put cardboard on it and drive like that for years. But we don't recommend doing this.

Solution

The problem of low temperature of the engine cooling system can be eliminated by installing a thermostat that opens at 92ºC. The WAHLER 3091.92D element performs excellently.

Original packaging of Wahler 3091.92d thermostat.

The element itself - the opening temperature is stamped on the body.

You just have to disassemble it and transfer the inside to Kalina’s original thermostat.

We saw off the plate, bend the body and take out the thermoelement.

We sharpen the spring so that the pressure point becomes flatter.

For comparison, thermoelements Wahler 3091.92d and the original one.

Be sure to use new gaskets and lubricate them with a small amount of sealant - this will prevent coolant leaks.

How to recognize a faulty thermostat?

• Long engine warm-up.
• Unreasonable increase in coolant temperature, or engine overheating.

The latter is the worst thing that can happen to you and your car's engine. For you, this means significant waste, big problems and wasted time. For the engine - reduced power, operational problems and inevitable overhauls.

Now let's talk about how to replace the thermostat if it fails. The popular VAZ model Lada Kalina will act as a test subject.

Replacing the Lada Kalina thermostat - necessary tools:

1. Screwdriver Set;
2. Two socket wrenches for “12″, “13″;
3. Silicone sealant;
4. Container for draining old coolant approximately (5 l);
5. 1-2 hours of free time;
6. Thermostat Lada Kalina.

Self-replacement of the thermostat VAZ 1118 (Lada Kalina) - detailed instructions

1. First, drain the coolant.

2. After this, you need to remove the air filter, to do this do the following:

• A . From the engine compartment side, unscrew the two upper bolts and the nut. Put all the parts in one place, this will allow you not to lose them during the process of replacing the thermostat.
• b . Now remove the connector located on the filter housing from the recirculation valve.
• V . Remove the valve by pulling it up. Move it along with the tubes a little to the side so that it does not interfere with your work.
• G . You need to remove the connector from the air sensor, then loosen the clamp and remove the air hose.

• d . By slightly loosening and turning, remove the air filter housing outward.

3. The next step is to remove the four hoses; to do this, loosen the clamps a little, use an “8” socket and a screwdriver. If the system is well pumped, then a lot of coolant should not leak out.

4. Using a “12” wrench, you need to unscrew the top nut of the thermostat in order to remove the ground wire.

5. Unscrew the stud and nut on the thermostat using a “13” wrench. Using slight loosening, remove the thermostat. Sometimes you have to use a screwdriver or other device for this, this is explained by the fact that over the years of operation the thermostat tends to “stick” to its seat.

6. Before installing the Lada Kalina thermostat, prepare the seat by clearing it of dust and dirt, as well as remnants of the old gasket.

7. Apply a thin layer of sealant 1–1.5 mm thick; if you don’t have sealant, you can use a special paper gasket.

8. Replacing the Lada Kalina thermostat is possible only when the surface is properly prepared and the applied sealant has time to crystallize. Allow the sealant to sit for 5 – 10 minutes and begin installing the thermostat.

Tool

To change the thermostat, you must first prepare the necessary tools and buy the thermostat itself.

The location of the thermostat on the Kalina engine is on the right side under the air filter.

• new thermostat;
• silicone-based sealant;
• 5 liter canister for draining coolant;
• socket wrenches (8, 12, 13);
• screwdriver set.

Work algorithm

Since the thermostat is located in the upper part of the block, the liquid can be drained not completely, but partially, using a simple device from a bottle and a hose.

Disconnect and dismantle the air filter.

We remove the old gasket (if there was one) and clean the seat.

The sealant can also be applied directly to the thermostat itself.

We check the tightness of all clamps and connect the connectors.

Fill antifreeze according to the marks in the expansion tank.

We start the car and warm up the engine to operating temperature.

Small and necessary level of antifreeze.

The choice of thermostat is a purely personal matter for everyone, which depends on the thickness of the owner’s wallet. The most popular thermostats are thermostats of the “LUZAR” brand; this company has proven itself well in the market for its price-quality ratio.

In addition, the Luzar company has a thermostat with an opening temperature of 92°C, which has a rather positive effect on warming up the interior in the cold season. Many Kalina owners install this thermostat in the winter.

Bottom line

Now we check whether we did everything correctly and how the new thermostat works. We start the engine and let it warm up to operating temperature. We touch the lower pipe, determining its temperature. If it is hot, then the thermostat is working as it should.

Do not forget to check the tightness of the connections between the pipes and the thermostat housing.
