Replacing the thermostat on Kalina - we do it ourselves, forgetting about car services

thermostat for engines 11183 and 21116, 21126

On grants with engines 11183 and 11186 (21116), 21126, a BEHR thermostat is used.

Thermostat elements:

1 – body; 2 – sealing ring; 3 – balloon; 4 – spring; 5 – fixing plate; 6 – cover

The thermostat consists of a metal cylinder with a heat-sensitive filler, a spring and its fixing plate. The cylinder rod fits into the socket of the thermostat housing. In the closed position of the thermostat (on a cold engine), its spring, resting on the fixing plate, presses the cylinder plate to the seat of the hole in the housing, closing the channel between the housing and the thermostat cover. As a result, the flow of coolant through the radiator of the cooling system is blocked. In this case, all the liquid circulates through a small circle of the cooling system: pump, cooling jackets of the cylinder block and cylinder head, thermostat housing and cover, heater radiator, steam exhaust hose of the cooling system radiator, expansion tank, pump supply pipe. When the coolant temperature reaches (85±2) °C, the thermostat bottle filler begins to melt and increases its volume, pushing the rod out of the thermostat bottle. In this case, the cylinder plate moves away from the seat, and the liquid begins to circulate in a large circle, which includes the pump, cooling jackets of the cylinder block and cylinder head, thermostat housing and cover, radiator of the cooling system, steam exhaust hose of the radiator of the cooling system, expansion tank, heater radiator, pump supply pipe. When the coolant reaches a temperature of (100±2) °C, the thermostat valve opens completely.

Coolant temperature sensor

The coolant temperature sensor installed in the thermostat cover provides information to the engine management system controller

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.

Differences in thermostat design.

The design of the thermostat uses a valve of a different design in contrast to valve 21082. The valve disc has an outer diameter of 29 mm, and valve 21082 has a disc diameter of 32 mm. Replacing one valve with another is possible thanks to a recess in the thermostat housing for valve 21082. If you install valve 21082, it is better to rub the seat with valve grinding paste. The rubber-coated valve Luzar 21082 does not require lapping. For those who like temperatures of 90-92 degrees, thermoelement TN 4898.92(J) It also needs to be removed from the body and rubbed in with lapping paste for 5-10 minutes (preferably). The best option for replacing the original thermoelement would be WAHLER 3091.92D. it has one bore diameter, but is rubberized and does not require lapping.

The thermostat is an indispensable part in every vehicle, be it a heavy truck or a passenger car like the Lada Kalina. If the thermostat device fails, it requires immediate replacement. Why might this happen? How to correctly perform the procedure for replacing the thermostat on a Lada Kalina? Car enthusiasts share their experiences in this article.

Features of the thermostat on the Lada Kalina

The thermostat in any vehicle regulates the temperature of the coolant. This process is necessary to avoid overheating of the internal combustion engine. Temperature control is carried out using a special valve installed in the cooling system. This valve is automated: when the coolant temperature is excessively high, it opens, and when it cools too much, it closes. Closing the valve during cooling is necessary. It is in this way that the time required for warming up a car engine during the cold season (winter season) is reduced.

The mechanism of operation of the thermostat device is as follows:

• two circuits are provided for the movement of coolant - large and small;
• for a quick warm-up procedure, the thermostat valve closes a large circle;
• as a result of automatic operation of the valve, the coolant begins to move in a small circle;
• when the coolant temperature reaches 85 degrees, the valve automatically begins to open;
• Full opening of the thermostat valve is observed at the moment when the coolant is heated to 100 degrees.

As you can see, the functioning of the thermostat is automated.

Cooling system Kalina important points of improvement

Safe driving of the vehicle depends on the uninterrupted and normal functioning of the Kalina cooling system. If the Lada's cooling system becomes airy, the car begins to overheat. This factor negatively affects the functionality of the motor.

Technical features of the system

The unified layout and closed design of the engine cooling system (SOD) of the Kalina are also characteristic of other VAZ models. The system is designed to remove thermal energy from heated engine elements using antifreeze or other coolant.

The SOD consists of the following functional parts.

1. Cooling radiator. Reduces coolant temperature due to the flow of cold air masses.
2. Fan. Used for rapid cooling of antifreeze in the Kalina cooling system.
3. Expansion tank. Designed to compensate for the volume of coolant (coolant). The need for this unit is related to the expansion/constriction property of the coolant.
4. A pump or centrifugal pump, which is responsible for the forced circulation of antifreeze through the appropriate channels.
5. A thermostat whose task is to regulate the volume of antifreeze in the Kalina cooling system.
6. Temperature sensor involved in SOD control.

The operation of the cooling system is based on the close interconnection of various parts, elements and sensors, including devices that are designed to measure oil temperature. The passage of coolant in a large or small circle depends on the engine temperature. In the first case, antifreeze passes through all components of the SOD, except the radiator. With such circulation, the thermostat is closed. As the engine temperature rises, this element gradually opens. The antifreeze, having passed a large circle, enters the radiator. The latter device is cooled by oncoming air masses. If this is not enough, a signal is sent to the ventilated unit, which begins to forcibly direct air masses to the cells.

The cooled liquid enters a small circle. Next, taking into account the engine temperature, the antifreeze automatically circulates in a small or large circle. At the same time, the optimal operating temperature is maintained, which should be in the range of 95-105°C. This factor has a direct impact on the performance of the Kalina stove. In this case, it will not be able to supply warm air masses into the cabin.

If there are any doubts about the operation of the ODS, you need to diagnose the car, finding out the causes of the malfunction. You can fix the breakdown either with your own hands or with the help of a car mechanic.

First, it is recommended to check the antifreeze level in the system. To do this, you will need to open the hood and inspect the expansion tank. It should be filled to 1/2 of the total volume. If necessary, antifreeze is topped up or the coolant is completely replaced. In the latter case, you will need to drain the old antifreeze. If there is a fluid leak, you need to inspect the engine compartment.

The main causes of ODS malfunctions

Coolant leakage is mainly due to the following reasons:

• presence of an old clamp;
• old or broken radiator.

In the first case, the unit is replaced, and in the second, repairs are carried out.

First of all, check the system pipes

Then you will need to check the circulation of fluid in the motor system in question. To do this, you need to see if antifreeze is entering the tank. If the result is negative, then replace the pump or clean the cooling system with special means.

If the Lada Kalina overheats, auto mechanics identify the following reasons for this situation.

1. The thermostat has failed. To check its functionality, you need to touch the radiator pipes. If the top element is cold and the bottom element is warm, the thermostat is stuck. In this case, a new unit is installed.
2. Clogged honeycombs. This problem usually occurs in late spring and early summer. In such a situation, clean the outer part of the radiator.
3. Fan malfunction. If this device does not turn on when the coolant temperature is high, you need to check the wiring and relay.
4. Presence of air masses in the SOD.

To solve the last problem, you will need to open the expansion tank. Start the engine, periodically press the gas pedal until the red mark is reached on the sensor. If the fan turns on, then you need to “add gas” by turning off the ignition. If it is not possible to eliminate the airlock using this method, more radical measures are used.

The plastic motor screen will need to be removed. To do this, he rises. Use a screwdriver to lower the clamp. Remove 1 of the 2 fitting tubes. Then remove the expansion tank cap. You need to blow into the container until antifreeze begins to pour out of the dismantled tube.

If it is not possible to break through the container, the lid closes. The tube is put in place. The engine warms up and the ignition turns off. Without dismantling the tank lid, remove the heating tube.

Important points of improvement

Coolant is considered a toxic substance that adversely affects human health. Auto mechanics recommend draining antifreeze with caution. When carrying out this procedure, you need to remember safety precautions and use rubber gloves. The antifreeze is drained when the engine is cold. Then the tube is put on the fitting, the clamps are tightened. Air masses have been successfully removed from the system under consideration.

Kalina's SOD needs improvement. Its modification involves the installation of a new 6-hole thermostat. This unit will maintain a stable fluid temperature, normalizing the operation of the interior heating devices.

Modification of the cooling system involves installing a coolant filter or a heater tap. To ensure that antifreeze passes through the channels faster and the risk of overheating is minimal, you will need to install an additional pump. You can tune the Kalina SOD yourself using the engine cooling system diagram.

Top 5 modifications to Lada Kalina

Hi all. This means that two years have passed since I owned this car, and as much as I remain satisfied with it, I have 5 life hacks for you that will help you when operating this car.

Well, I think that thanks to these life hacks, your car will also make you happy. Because the car, in this case, is mine for the sixth year, 2006, and there were some problems that it would be advisable to eliminate immediately.

Something is not a jamb, something, well, more has been done to improve it. Well, I still want to share with you, maybe this video will be useful to someone. So let's go.

1. Lifehack No. 1
2. Suspension
3. The stove doesn't heat well
4. Mirrors
5. Tunnel of shelves

Lifehack No. 1

This is Kalina's ECU, that is, almost all of Kalina's owners have probably encountered it; those who haven't, they already know about the drawback in the location of the ECU. Initially, Kalina's ECU is located here under the panel.

And there is a stove above the ECU, and Kalina’s stove tends to leak, but we’ll talk about this later, why and how. When the radiator leaks, the heater usually floods, which means the brains of the ECU.

That is, the ECU costs, I have a Boshev one, it costs about 7 - 8000. Like any other ECU, that is, approximately, that is, any other ECU in this area costs. Here, no matter what your situation is, that is.

Here's how I solved this problem? That is, immediately when I bought the car, I got it from there, screwed it on there with these covers and installed it here.

This is how I have it located here, here I have the lighting for the legs, that is, here, I placed it under the glove compartment, there it does not bother anyone, no one kicks it, as I initially thought that they would touch it with their feet, no one doesn't hurt, doesn't interfere with anything.

That is, I secured it with two bolts, the first, the second and that’s it. That is, this is enough. It stays here, nice, warm and dry. That is, I think this should be done first of all when buying Kalina.

Because if your brain is flooded, it’s a waste of money, which is unnecessary, so first of all, those who don’t know yet, be sure to do it. It literally takes 20 minutes and will save your wallet very well.

Suspension

So, then, the second thing I would like to talk about is the suspension. How did I encounter the suspension? That is, it didn’t leak, it didn’t knock or anything, but it kind of rattled, not just knocked, it sort of rattled and rattled, it was here, there were some knocks in the supports, that’s it, and so on.

In short, I read and realized that the Grant suspension, that is, it was better designed, the Kalinovsky jambs in the supports were removed, well, in short, without hesitation, I bought Grant struts assembled with supports, with springs, everything, both front and rear.

Here. I went to Avito, searched for Grant and found a broken Grant with 15,000 miles on it, so they were bought from it, I paid 3,000 rubles for all the racks. That is, the front, the back, everything is assembled, here.

That is, the suspension was changed about six months after the purchase, that is, a year and a half later, I did not regret at all that I installed it.

Now, since it has proven itself only from the best side, no noise, very soft, pleasant. Exactly, that is, the main thing is that there is a drain, that’s it. That is, I really liked the pendant, so I kind of recommend it.

The stove doesn't heat well

The second thing I encountered when owning this car is that the heater does not heat up enough. That is, well, sometimes it seemed like there wasn’t enough heat, that’s it. Plus airing the system and so on.

I also read it and realized that this was also done better on Grant than on Kalina. Well, as it were, Granta is the same Kalina, that is, with the jambs eliminated. That's why many people installed a Granta thermostat.

I installed it too, but you won’t be able to see it here. I installed, here, a Grant thermostat. That is, what are the advantages? It has much less, it has much less pipe of any kind.

That is, it is generally simpler. I'll leave you a link under the video to my DriveDvorra, where I have everything chewed up. So, what’s the point, that is, who is interested in Grant’s soda and in general in what I’m talking about, in general in all the alterations, that is, go in and read there.

What can I note, then, after the rework? Now, the main advantage here is that the contour is small, when I sit in the car, the wind is blowing - it’s inconvenient to talk about.

A small cooling circuit on the Grant thermostat, it goes, that is, the engine and the heater radiator, that is, what do we get? We start the car, as soon as the engine warms up, it immediately releases heat into the interior onto the radiator.

That is, before, if I was driving to work in winter, that is, I literally had to get to work so that it would become more or less warm in the car, now, that is, it’s enough to drive, well, warm up a little and drive a couple of kilometers .

And that’s it, it’s already kind of warm in the car, that’s it. That is, this is the main advantage. There’s no airing, there’s none of that. But, that is, the point is airing, you will have air in the stove, well, the stove there is, in general, a honeycomb, but alteration will not help.

You also need to monitor the condition of the cap on the expansion tank. For myself, I found such caps, which means they are, well, a cap for the expansion tank, it’s called “Avtopribor”, in a blue box it says “Avtopribor”, these are good caps.

But once a year I still try to change them. Well, here the opinion of potassium growers is generally divided, that is, into two types. Some say that it’s better not to mess with your native system, it’s just that you have a handicap there, that’s not the point, there are those who seem to change and are happy.

Here. I am one of those who change and am happy and have not regretted it at all. In terms of money, it all worked out, I installed all the pipes there that were needed, well, I installed everything new in short, it came out to about 3000, I don’t regret it at all, that is, there are only advantages.

Mirrors

The next thing I would like to note when owning a Gran, oh Kalina, is the mirrors. That is, mirrors from 2006, I won’t even say, to be honest, at what price, they cost very small drops like this, those who have them know that after restyling they already have these.

That is, I cannot skip this point. Mirrors, they are small and uncomfortable. Here. That is, I decided to change it. Since I still didn’t have enough heating, I also bought mirrors like this from Granta.

The mirrors are very comfortable and have a good view. That is, some advantages. Plus they come with heating. Here. They fit into their standard places without any modifications. That is, when you remove the old one, this one from Granta also comes in without any problems.

Here, the plus goes here, which means heating, I just ran a wire, it connects to the heated rear window button. That is, the Internet is also full of information on this topic, heating is also very convenient.

Tunnel of shelves

So, well, that means the last thing I would like to focus on today regarding the remodeling in Kalina is the tunnel, the tunnel of Kalina shelves. This means that whoever has the standard one, they know that there are not enough cup holders, first of all.

Well, in general he is so familiar, in short, not interesting. Here. This means that I installed the Granta tunnel and it fits very well, in its normal place. Here, the only thing is... Kalinovsky, he understands here, but Grantovsky is a complete success.

That is, we have switches there, fuses, for access to this ECU, for someone who has not yet transferred it. So, for the sake of reliability, that means I also sawed the Grant tunnel.

Just like that, I simply assembled it with self-tapping screws, well, it doesn’t catch the eye as it seems at first glance, but on the other hand, if a fuse or relay suddenly blows out, then I can easily change it.

And so, there are only advantages, that is, it is very convenient to go somewhere with cup holders. That is, these bottles and glasses don’t fly around the cabin. Cigarette lighter, cigarette lighter, so we remove it.

I bought this splitter for 2 and simply connected it to these wires that went to the cigarette lighter. Very convenient, only one plus. This one also needs to be installed with a cover from Granta, plus I immediately installed the handle.

Remaking the handle, how to make a handle so that it fits here, I also have a recording in the drive. Here are the links again in the description. Heated seats. My seats are not original, that is, if you have original seats, just connect them this way.

My seats are not original at all, the seats are from Opel Omega. Here. I have an electric drive. These are the seats. The heating is connected, that's all. But today, as they say, that’s not what they’re talking about.

So, well, I told you everything I wanted. That is, the top 5 of your modifications to the car. This is natural, these are not all the modifications that are in this car, I did a lot of things in my free time.

The car is used every day, unlike the six. Six so, for the soul, for the project.

And Kalina is on everyday life, no, it’s all the same, she’s like before the creation of the channel, a lot has been done with her, a lot will still be done. That is, I like the car, I’m going to drive it.

How to check the thermostat sensor on Lada cars.

Causes of thermostat malfunction on Lada Kalina

Experienced auto mechanics name several main reasons why the thermostat device on a Lada Kalina car may fail.

1. Lack of coolant circulation, both in large and small circles.
2. Corrosion of metal parts of the cylinder and locking pin.

You can determine a malfunction of the thermostat on the Lada Kalina by the following signs:

• prolonged warming up of the engine (that is, it takes a long time for it to reach operating temperature);
• rapid overheating of the internal combustion engine;
• non-standard internal combustion engine temperature indicators (at speed the temperature is less than the standard temperature, after stopping it is more);
• rapid heating of the lower pipe (its temperature rise is observed after just a few minutes of engine operation).

Step-by-step replacement of the Lada Kalina thermostat (on your own in a garage)

The first stage is preparatory. You should immediately prepare all the tools that may be needed during the thermostat replacement procedure. So, the car enthusiast will need:

• car screwdrivers;
• socket wrenches – No. 12 and No. 13.

It is also necessary to immediately prepare a 5-liter container to drain the used coolant into. Purchase silicone sealant and a new thermostat device suitable for the Lada Kalina car.

The second stage is draining the coolant.

The third stage is removing the air filter:

• Unscrew the bolts and nut (they are located on the engine compartment side);
• Remove the air filter housing connector from the recirculation valve;
• remove the valve itself (this must be done with a smooth upward movement);
• remove the connector from the air sensor;
• loosen the clamp;
• remove the air exhaust hose;
• dismantle the air filter (to do this you will have to loosen its housing a little and turn it to the side).

The fourth stage is dismantling the thermostat device itself. It is performed according to the following instructions:

1. Hoses are removed - 4:
2. loosen the clamps (you will need a No. 8 socket wrench and a screwdriver);
3. drain the remaining coolant.
4. The ground wire is removed:
5. Unscrew the top nut of the thermostat device (you will need a No. 12 wrench).
6. The thermostat is removed:
7. unscrew the pin;
8. unscrew the nut (wrench no. 13);
9. slightly loosen the thermostat in the seat;
10. extract it.

Thermostat

- an integral component in the cooling system of a car engine. Its task is to maintain the optimal temperature of the coolant (coolant) in the system by opening or closing the valve, on which the flow of the coolant in a large or small circle depends. The thermostat prevents engine overheating, and in the cold season it can significantly save fuel and the time required to warm up the engine to the optimal temperature. A working thermostat opens at a temperature of 85 °C and already at 100 °C it is fully open.

The thermostat is completely mechanical and works exclusively according to the laws of physics. Using a solid heat-sensitive element, which melts when heated and allows the damper to open, releasing coolant in a large or small circle. Faulty thermostat

can most often be detected by the following signs:

• Increasing the time required to warm up the engine
• Increased temperature and even overheating of the engine.

Engine overheating is the worst thing that can happen due to a broken thermostat. I don’t think it’s worth explaining what this means for the car owner. Therefore, without unnecessary preambles, I propose to move on to the issue of replacing the Lada Kalina thermostat.

Replacing the Lada Kalina thermostat will require the following from you:

1. Thermostat Lada Kalina.
2. Socket wrenches for “12”, “13”.
3. Silicone sealant.
4. Phillips screwdriver.
5. Container for coolant (5 liters).
6. Free time 1-2 hours.

Installation of a thermostat from Granta

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:

• The thermostat is mounted on studs and screwed with nuts.
• 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.
• 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.
• 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.
• 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.

Do-it-yourself replacement of the VAZ 1118 thermostat - detailed guide

1. Before starting disassembly, you need to drain some of the coolant.

2. Then remove the air filter, this is done as follows. You can read how to do this in the article:.

A

. Unscrew the top two screws and the nut from the engine compartment side. So that you don’t have to look for anything later, I recommend putting all the parts in one place.

V

. Pull the valve up, then move it and the tubes to the side.

G

. Remove the connector from the air sensor, loosen the clamp and remove the air hose.

d

. Slightly loosen and slightly turn the air filter housing and pull it out.

3. Using a screwdriver and a socket on “8”, you need to loosen the clamps, then remove the four hoses. A well-bled system will not leak much coolant.

6. Next, you need to clean the seat from dirt. Remove any remaining old gasket and wipe the area with a clean cloth. Apply the sealant in a thin layer of 1–1.5 mm or use a special paper gasket.

7. It is now possible to replace the Lada Kalina thermostat

. If you used sealant, allow it to crystallize; this requires waiting 5 to 10 minutes.

8. Install the new thermostat, do it in the reverse order of removal, and do not forget to move the temperature sensor from the old thermostat and screw the ground wire onto the upper mounting stud.

9. Connect all hoses and add the required amount of coolant to the cooling system using the air lock removal technique.

10. Start the engine and carefully inspect all connections for leaks. If you find a leak, be sure to tighten the clamps.

When completed, all of the above problems with engine heating should disappear. Check the operation of the thermostat; to do this, while driving, pay attention to the temperature, it should be around 90 ° C.

Thermostat price

The approximate price of a thermostat cover with a sensitive element in our stores is 450 - 700 rubles . When choosing a spare part, it is better to give preference to branded VAZ models. The catalog number of the Lada Kalina thermostat is 1118-1306010.

The cost of replacing this unit ranges from 500-800 rubles.

In order not to overpay for the work, you can replace the thermostat yourself, but before that, do not forget to check it using the method described above with heating water.

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.

Checking for correct installation

It is very easy to check the correct installation and operation of the thermostat in the Lada Kalina. Here you will need to warm up the engine and then immediately turn it off. Next, open the hood and feel for the lower pipe that goes from the radiator to the cooling jacket of the engine block. If it is heated, the thermostat opens, and there is no risk of the Lada Kalina engine overheating. When this phenomenon does not occur, the system components require careful diagnosis. Therefore, it would be a good idea to check the functionality of the new thermostat before installation.

How to recognize a faulty thermostat?

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

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.

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:

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, in order to do this, you have to use a screwdriver or other device, 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 landing gear, to do this, clean 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. is possible only when the surface is properly prepared and the applied sealant has had time to crystallize. Allow the sealant to sit for 5 – 10 minutes and begin installing the thermostat.

10. Screw the ground wire back onto the top mounting stud.

11. All that remains is to connect the hoses and pour coolant into the cooling system. Remember about “air pockets” that must be removed.

12. Upon completion of assembly, check the tightness of all connections; to do this, you need to start the engine. Take your time and carefully inspect all connections and make sure there are no leaks. If necessary, tighten the clamps.

After replacing the Lada Kalina thermostat

All of the above symptoms and signs of thermostat malfunction should disappear. Make sure the thermostat is working correctly; to do this, you need to go out on the road and pay attention to the coolant temperature, it should be within 90 °C.

The cooling system on the first generation Lada Kalina, unfortunately, is far from perfect. There are 3 common problems: the heater radiator is leaking, the thermostat is not working, and air is leaking from the outside.

Consider one problem - a malfunctioning thermostat on Kalina.

Symptoms of a faulty Kalina thermostat:

• the car does not warm up to operating temperature (90 +-10 degrees)
• the car overheats: the engine temperature is over 90 degrees even when driving

It is worth noting that cold air from the heater at a high engine temperature (sometimes the heater blows hot only after re-gas) indicates the presence of an air lock in the cooling system. Do not confuse this with a faulty thermostat. It is advisable to remove all air pockets from the cooling system before diagnosing the thermostat.

So, we know for sure that the thermostat in our Kalina is broken and we want to replace it with our own hands.

a new thermostat as a whole or part with a thermoelement (it’s better to take the whole thing.)

You will probably need a gasket securing the thermostat to the engine block (if you are replacing the whole thing)
