Thermostat VAZ 2106
An element of a vehicle’s liquid cooling system, such as a thermostat, is a device with which the vast majority of passenger cars are equipped. It is located in the engine compartment in the space around the engine in the pipeline network between the power plant and the radiator. Externally, it is a sealed cylinder made of light alloy materials with holes, to which the cooling system pipes are connected.
Replacement
To replace the thermostat on VAZ 2106 cars, you need to drain some of the coolant by unscrewing the drain plug on the cylinder block. It is also necessary to remove the battery, which will interfere with our ability to carry out repairs to replace the thermostat. Next, loosen the clamps securing the hoses to the thermostat and disconnect the hoses, then remove the thermostat.
After removing the thermostat, it must be checked for functionality; to do this, lower it into a container with water heated to 78-80 degrees and, with constant stirring, continue to heat the water to 87-90 degrees. The thermostat valve should slowly begin to open; if this does not happen, the thermostat must be replaced. Install the new one in reverse order. Fill with coolant.
How to change the ignition switch follow the link.
How to check
Before removing and checking the functionality of the thermostat, make sure that engine cooling problems are not due to insufficient coolant or low drive belt tension. Make sure the indicator located on the instrument cluster is working properly.
If you notice that the engine takes a long time to warm up to operating temperature (according to the indicator), the thermostat may be stuck open. In this case, the thermostat should be replaced.
On the other hand, long warm-up times may be due to the lack of a thermostat. This could have been done on purpose or unintentionally (they forgot to install it after repair). Do not use a car without a thermostat. The engine management system will keep the engine in warm-up mode for a longer period of time. During this time, the engine will consume more fuel, and the exhaust gases will contain more harmful impurities.
If the engine is overheating, touch the upper radiator hose. If it is not hot and the engine is overheated, the thermostat may be stuck closed. The liquid does not enter the radiator and circulates in a small circle. In this case, replace the thermostat.
If the upper radiator hose is hot, this means that the thermostat is open and fluid is circulating normally through the system. In this case, read the recommendations given in the Fault Diagnostics Section.
Checking by removing the thermostat
Remove the thermostat (see Section Removing and installing the thermostat).
If the thermostat is open at room temperature, it is faulty and must be replaced.
To make a rough test of the thermostat's functionality, hang it on a piece of twine in a container of water. The thermostat should not touch the walls of the container. Start heating the container.
As the water heats up, the thermostat should open (this happens just before the water boils). Since the boiling point of water is 100°C, the thermostat may not open completely (refer to Specifications). Remove the thermostat and let it cool. As it cools, it should close completely.
If the thermostat does not open when heating or does not close when cooling, replace it.
When installing the thermostat, pay attention to the following points:
a) Thoroughly clean the mating surfaces and replace the O-ring;
b) Place the thermostat in the housing, oriented correctly;
c) Tighten the cover mounting bolts using the required force;
d) Install all hoses in their original places, then fill in coolant (refer to the Chapter Routine care and maintenance);
e) Start the engine, warm it up to operating temperature and check for leaks.
How to change
To replace the thermostat on the “six” you need a minimal set of tools - essentially one screwdriver. First you need to drain the coolant (but not all, only part). To do this, you need to unscrew the plug from the fluid drainage system in the cylinder block. After this, proceed to remove the battery. The thermostat itself is very easy to remove - you just need to loosen the three clamps that secure the pipes to the thermostat, disconnect the pipes themselves and remove the thermostat.
Before installing a new device, you need to check it - put it in hot water (about 80 degrees), after which the water needs to be heated and stirred constantly, thereby bringing it to about 87 degrees. If the main valve opens, then the thermostat is working.
Malfunctions
Reason: it is jammed or the valve plate is stuck.
Signs: the temperature display is already beyond the red mark, and the radiator is still cold to the touch.
Possible consequences: Driving with the thermostat closed can cause severe engine damage. The cylinder head gasket may burn out, the cylinder head may become deformed, or cracks may appear on it.
Remedy: Wait until the engine has cooled, unscrew the thermostat housing and remove the thermostat. Driving without a thermostat for a while will not harm your engine.
Thermostat does not close completely
Cause: A foreign object has entered the thermostat.
Symptoms: After starting a cold engine, the radiator immediately becomes as warm as, for example, the thermostat housing. The car interior heats up slowly.
Possible consequences: If the engine does not reach operating temperature, wear on its parts increases.
Remedy: Replace the thermostat.

How to choose the right thermostat for a VAZ 2106?
I’ll tell you, as a long-time car enthusiast, you should only buy original spare parts from the manufacturer.
The thermostat is no exception.
After all, the work of one node directly affects the work of other nodes and it is necessary to make some “improvements” either comprehensively, or refrain from doing so altogether.
First of all, you need to remove the thermostat to get an idea of what it looks like.
Further information is needed.
Manufacturer country. in our case it is Russia. City of Togliatti.
This means that the original thermostat is produced at the Volzhsky Automobile Plant, we are not considering a license, imported ones and especially Chinese ones are the same.
Next we look for information about the price. You can go online, you can go to several stores.
Based on the price, we find out about the cheapest ones and immediately exclude them (probably Chinese).
Then we exclude the most expensive ones; VAZ thermostats for classics can also be produced by France (for example), the price is higher, but the quality is no better, and often worse.
Next, we collect information; all classic models up to 7 have the same thermostats, which means we don’t get hung up on the 6.
Suitable from 01, 02, 03, 04, 05, 0.63, 07.
The original packaging must have the VAZ logo, it looks like this.
Now look at the removed thermostat, only the series numbers and production dates should differ, all other numbers should match.
This is the main thing.
Of course, there are thermostats of good quality produced under license, in this case you just need to find out whether this manufacturer has a VAZ license.
This information can be obtained on the Internet.
the moderator chose this answer as the best
There are no special nuances in choosing a thermostat; it is a fairly durable and reliable part.
I just wanted to warn you that when purchasing you need to choose one exactly similar to yours, it is better to take it with you for a sample in order to measure the thickness and dimensions.
Naturally, buy a high-quality part, ask the manufacturer, and also visually inspect and compare yours and the one you are buying in terms of quality, wall thickness and weight.
Be sure to take a receipt and a note so that if the quality is poor, you can return the part and get your money back, or exchange it for another part.
Before installing the thermostat it is very easy to check this can be done using a kettle and a cold water tap

Yes, you can figure out these thermostats when you know your machine confidently. But I want to give you some practical advice, I myself assembled cars for the taiga and winter, so always take the thermostat that is specified by the manufacturer. Firstly, it provides all the parameters for the operation of the motor, so it is perfectly suitable for car 06. I would like to give you one more piece of advice: before installing the thermostat, check the thermostat before installing it, lower it into water heated to 78-80 ° C. Heat the water, stirring it constantly, to (87±2) °C. at a temperature of (87±2) °C, the main thermostat valve should begin to open. If this does not happen, the thermostat needs to be replaced.

Purpose of the thermostat on the VAZ 2106
The thermostat must control the degree of heating of the coolant and react in a timely manner when the antifreeze temperature becomes too high or, conversely, too low.
The device can direct coolant through either a small or large cooling circle, thereby preventing the engine from overheating, or, conversely, helping it quickly warm up after a long period of inactivity. All this makes the thermostat the most important element of the VAZ 2106 cooling system.
Thermostat location
The thermostat in the VAZ 2106 is located to the right of the engine, where the pipes for discharging coolant from the main radiator are located. To see the thermostat, simply open the hood of the car. The convenient location of this part is a big plus when it becomes necessary to replace it.
Principle of operation
As mentioned above, the main task of the thermostat is to maintain the engine temperature within specified limits. When the engine needs to warm up, the thermostat blocks the main radiator until the engine reaches the optimal temperature. This simple measure can significantly extend the life of the engine and reduce wear on its components. The thermostat has a master valve. When the coolant reaches a temperature of 70 °C, the valve opens (it should be noted here that the opening temperature of the main valve can be higher - up to 90 °C, and this depends both on the design of the thermostat and on the thermal filler that is in it used).
The second important element of the thermostat is a special compression cylinder made of brass, inside of which there is a small piece of technical wax. When the antifreeze in the system reaches 80 °C, the wax in the cylinder melts. As it expands, it presses on the long rod connected to the main thermostat valve. The rod extends from the cylinder and opens the valve. And when the antifreeze cools, the wax in the cylinder begins to harden, and its expansion coefficient decreases. As a result, the pressure on the rod weakens and the thermostatic valve closes.

If the VAZ 2106 engine suddenly began to overheat for no apparent reason, most likely the thermostat has failed. This is a very small device that at first glance seems insignificant. But this impression is deceptive: if there are problems with the thermostat, the car will not go far. Moreover, the engine, overheating, may simply jam. Is it possible to avoid these troubles and replace the thermostat yourself? Undoubtedly. Let's figure out how this is done.

Types of thermostats
The VAZ 2106 car was produced for many years. And during this time, engineers made a number of changes to it, including thermostats. Let's look at what thermostats were installed on the VAZ 2106 from the release of the first cars to the present day.
Single valve thermostat
Single-valve thermostats were installed on the very first “sixes” that rolled off the VAZ assembly line. The operating principle of this device has been described in detail above. To date, these devices are considered obsolete, and finding them on sale is not so easy.
Electronic thermostat
An electronic thermostat is the latest and most advanced modification that replaced single-valve devices. Its main advantages are high accuracy and reliability. Electronic thermostats have two operating modes: automatic and manual.
Liquid thermostat
Thermostats are classified not only by design, but also by the type of fillers. Liquid thermostats were the very first to appear. The main component of a liquid thermostat is a small brass cylinder filled with distilled water and alcohol. The operating principle of this device is the same as that of the wax-filled thermostats discussed above.
Solid thermostat
The filler in such thermostats is ceresin. This is a substance similar in consistency to regular wax, which is mixed with copper powder and placed in a copper container. The cylinder has a rubber membrane connected to a rod, also made of dense rubber that is resistant to high temperatures. Ceresin, expanded from heating, presses on the membrane, which, in turn, acts on the rod and valve, ensuring the circulation of antifreeze.
Which thermostat is better
Today, thermostats based on solid fillers are considered the best option for the VAZ 2106, since they have the optimal combination of price and quality. In addition, they can be found in any auto store, unlike liquid single-valve ones, which are practically no longer on sale.
Which thermostats to choose for VAZ (Lada) 2101/2103/2106?
Last month, PartReview users preferred LUZAR. 60% of positive votes belong to this manufacturer.
Gates thermostats came in second place with 20%.
Vernet closes the top three with 20% of the votes.
In the general rating of thermostats, which takes into account the opinions of owners of different brands and models of cars, these brands occupy the following positions:
- LUZAR received 8th place, PR score - 66. Data from 72 reviews and 229 votes are taken into account.
- Gates is ranked 10th with a PR score of 56 based on 72 reviews and 89 votes.
- Vernet is ranked 6th with a PR score of 70. Data from 66 reviews and 202 votes are taken into account.
Signs of a broken thermostat
There are a number of signs that clearly indicate that the thermostat is faulty:
- The light on the instrument panel is constantly on, indicating that the engine is overheating. This usually happens because the thermostat valve has closed and is stuck in that position;
- The engine warms up very poorly. This means that the thermostat valve does not close tightly. As a result, antifreeze flows through both the small and large cooling circles and cannot warm up in a timely manner;
- After the engine starts, the lower thermostat tube heats up literally within a minute. You can check this by simply placing your hand on the nozzle. This situation indicates that the thermostat valve is stuck in the fully open position.
If any of these symptoms are detected, the driver should replace the thermostat as soon as possible. If the car owner ignores the above symptoms, this will inevitably lead to overheating of the engine and its jamming. It is extremely difficult to restore an engine after such a breakdown.
Replacing the thermostat
This action can be performed in the event of a device failure. The thermostat is replaced if there is any doubt about its performance. This occurs when violations of the temperature range of the power plant are detected or when it is determined that it has not fully warmed up. It is not necessary to completely free the cooling system from antifreeze.
A routine check of the thermostat is carried out as follows: when starting the engine, it is necessary to check the temperature regime of the lower tubular outlet of the radiator, which ideally should be cold to the touch. After the antifreeze reaches a temperature of 87-92 °C, the lower outlet pipe should become warm. Otherwise, the device must be removed and checked for functionality.
Maintenance and repair work on this device should begin with the engine cooled down and the battery removed for convenience. In a VAZ 2106, replacing the thermostat is carried out with a set of driver's tools in the following order:
- We drain a certain amount of antifreeze by unscrewing the drain plug in the engine block.
- We dismantle the battery.
- We loosen the clamps of the clamps on the pipes leading to the thermostat, remove the pipes and the thermostat itself.
- We check the thermostat by lowering it into hot (78-80 °C) water. We bring the liquid temperature to 87±2 °C, at which the main valve of the device should open. If this is not the case, it is necessary to replace the thermostat in the cooling system.
- We install the new product in reverse order. To prevent cases of antifreeze leakage from the system connections, it is necessary to lubricate them with a sealed lubricant before tightening the pipes.
- Fill the radiator with antifreeze and squeeze out any air pockets from the system.
- This completes the work on replacing the thermostat.
In winter, when the stove is turned on, the temperature value becomes lower. This is a natural process and the standard thermostat cannot affect the thermoregulation of the cooling and heating system in any way. The car receives full heating of the interior only during long trips, and during short driving intervals followed by turning off the engine it does not really warm up.
To achieve room temperature conditions in the cabin, modification of the thermostat is required, the results of which will achieve the final goal - timely heating of the cabin. Achieving this result is only possible by directing the antifreeze back to the thermostat, since this product regulates the cooling process.
For this purpose, it is necessary to resolder the body of the device and direct the pipe from the pump to the thermostat, and install a reliable chopper into the hole in the pump, which will eliminate the possibility of coolant leakage. After modifying the thermostat, the temperature regime changes and the interior heats up much faster.
Methods for checking the thermostat
There are four main ways to test the thermostat's functionality. We list them in increasing order of complexity:
- The engine starts and idles for ten minutes. After this, you need to open the hood and carefully touch the lower hose coming out of the thermostat. If the device is working correctly, the temperature of the lower hose will not differ from the temperature of the upper one. After ten minutes of operation they will be warm. And if the temperature of one of the hoses is significantly higher, the thermostat is broken and needs to be replaced.
- The engine starts and idles. After starting the engine, you need to immediately open the hood and put your hand on the hose through which antifreeze enters the upper part of the radiator. If the thermostat is working properly, this hose will be cold until the engine warms up properly.

How to check the thermostat without removing it from the car
The thermostat is a key component of the cooling system, which is responsible for high-quality engine warm-up by timely redirecting coolant flows in a small or large circle.
Failure of this unit inevitably leads to a number of problems - overheating of the power unit or the inability of it to reach the desired temperature.
That's why a car enthusiast needs to know how to check the thermostat and what malfunctions of this device exist.
We independently change the thermostat on a VAZ 2106
Before starting work, you should select tools and consumables. To replace the thermostat we will need:
- new thermostat;
- coolant (5 liters);
- basin for draining old antifreeze;
- flat screwdriver.
It should be noted here that the thermostat cannot be repaired. The reason is simple: inside it has a thermoelement with liquid or solid filler. It is the one that fails most often. But such elements are not sold separately, so the car owner has only one option - replacing the entire thermostat.
Sequence of work
Before performing any manipulations with the thermostat, you need to drain the coolant. Without this operation, further work is impossible. It is convenient to drain antifreeze by placing the car on an inspection hole and unscrewing the cap of the main radiator.
- After draining the antifreeze, the car hood opens. The thermostat is located to the right of the engine. Three hoses come to it.
Video: changing the thermostat yourself
So, the owner of a VAZ 2106 does not need to go to the nearest car service center to replace the thermostat. Everything can be done with your own hands. This task is entirely within the capabilities of a novice driver who has at least once held a screwdriver in his hands. The main thing is not to forget to drain the antifreeze before starting work.

Which thermostat is better to choose and install on your VAZ-2107 if the old one has failed
In recent years, manufacturers of parts for VAZ have been rapidly multiplying. And not all of them offer high-quality products; most sell consumer goods that won’t last even a month.
It is better to change the thermostat in the winter, unless it is so broken that it cannot be delayed.
- Judging by the reviews of VAZ owners, the factory device works for a maximum of 3-4 years, and it begins to jam on a large circle, which is not so fatal, but also not good for the car.
- Polish WEEN products are recommended by almost everyone who has dealt with them. They keep the antifreeze temperature at any time of the year, but their operating period is 2 years from the manufacturer, but sometimes they cannot withstand more than 1.5 during intensive use of the car.
- PRAMO ThermostATO from Russia has a bad reputation because the thermoelement is poorly regulated, which does not open completely or late, turning on the fan at each stop. It often jams on a small circle, which is fraught with damage to the engine.
- BAUTLER from China is not an option when spare parts from the Land of the Rising Sun are better than domestic ones. The motor temperature does not rise above 85º C. Suitable if you remove it for winter and use it only in summer.
- PRAMO with a Polish thermoelement, made in Russia, is excellent in operation and easy to adjust. The valve does not turn on even in traffic jams, but after a long drive during the day it can remind you of itself. Warms up the engine quickly and runs for a long time in any season.
If you do not trust the words of the sales consultant, try to check the selected thermostat on the Internet before purchasing. Reviews from uninterested users are very rarely false.

As a result, the pressure on the rod weakens and the thermostatic valve closes.
By opening the valve here we mean moving its leaf by only 0.1 mm. This is the initial opening value, which consistently increases by 0.1 mm as the antifreeze temperature rises by two to three degrees. When the coolant temperature rises by 20 °C, the thermostat valve opens fully. The full opening temperature can vary from 90 to 102 °C depending on the manufacturer and design of the thermostat.
