Correct selection and replacement of the thermostat on Priora. How to change a Priora thermostat 16 valves

The thermostat in the Priora is a small but very important element of the car's cooling system. Its task is to regulate cooling processes by directing antifreeze at the required moment. In one case, circulation occurs in a small circle, in the other along a large path.

The fact is that when the internal combustion engine just starts and does not warm up to operating temperatures, the thermostat valve is closed, thereby preventing the movement of antifreeze through the radiator. Another thing is when the internal combustion engine becomes hot, in this case the valve opens and promotes the movement of coolant in a large circle through the radiator. Thus, the liquid transfers its heat to the radiator as quickly as possible and then moves through the system in a cooled state. But what if there is a problem with the regulator? The answer is obvious - the internal combustion engine will overheat, and hence a number of serious problems.

What is a thermostat on Priora

The thermostat on the Priora is the main sensitive component of the car's cooling system. In a Lada Priora car, the thermostat is located between the engine and the radiator. Despite its small size, about 5 cm in diameter, it has two valves: bypass and main.

Replacing the thermostat on a Priora usually becomes necessary when the main valve malfunctions. It has a cylinder made of heat-sensitive material with a wax ball and rod inside. When heated above 82 degrees Celsius, the wax melts and expands, pushing the rod out. Thus the valve opens. And vice versa, when wax hardens, it decreases in volume. The valve closes. For a Priora car, the thermostat in the photo is shown in section. Its internal structure is shown.

The uninterrupted operation of the thermostat on the Priora keeps the engine temperature at a normal operating level. When the engine warms up, the Priora thermostat valve is closed, the opening temperature of which is 90-95 degrees. Accordingly, coolant does not flow to the radiator. The temperature in the system increases faster, engine wear and harmful emissions into the atmosphere are reduced, and your time and fuel are saved.

What is a thermostat for?

The car's thermostat serves to maintain normal operating temperature of the engine and protect it from overheating. Without it, the car would overheat and would not allow the interior to be heated. Also, negative temperatures would have a bad effect on the engine, leading to various malfunctions and increased fuel consumption.

The main purpose of the thermostat

Basically, the diameter of this device is no more than 5 cm. It is located between the radiator and the car engine and can be in a separate housing or built into the cylinder head. The main purpose is to maintain normal operating temperature of the engine. This happens as follows: until the engine temperature reaches 95 degrees Celsius, this device blocks the supply of coolant, but as soon as the critical point is reached, the device instantly opens the valves and the engine is cooled.

Thermostatic mechanisms regulate the temperature of the motor and, by helping it warm up faster, increase its service life, which will save the family budget. In addition, they perform very important functions in environmental terms, as they reduce the emission of very harmful exhaust gases into the atmosphere. Breakage or incorrect operation of such a part is undesirable, which means we must be able to identify the problem in time and fix it.

Thermostat operating principle

The thermostat consists of a housing and a thermoelement. The main role is played by the thermoelement. The thermocouple is built into the housing and covers one of the holes in the thermostat cover. When the temperature reaches 85 degrees, the thermoelement opens.

Direct work on the car is that when the thermoelement is closed, the coolant circulates in a small circle, bypassing the engine cooling radiator; as soon as the coolant temperature reaches 85 degrees, the thermoelement opens and coolant circulation begins in a large circle through the radiator.

So during the entire operation of the engine, the thermoelement opens and closes a huge number of times.

Checking the Thermostat

Most often, drivers notice a thermostat malfunction during the cold season. Since a car engine at low temperatures cannot heat up to operating temperature. Based on the fact that the engine temperature is below normal, the heater will not be able to heat the interior to a comfortable temperature.

The thermostat is checked on a cold engine.

We start the engine and touch the lower radiator pipe. It should be cold, not warm, but cold is very important. When the temperature reaches 85 degrees, the lower pipe should become hot. If the check on your car shows the opposite, then the thermostat is most likely faulty.

The thermostat will also be faulty if, when starting the engine, after some time the lower radiator hose becomes warm, then most likely the thermocouple is jammed or does not completely close the large circuit.

How to check the thermostat without removing it from the car? Signs of a bad thermostat

The thermostat is a small part in the mechanism of an internal combustion engine that is responsible for the operation of the cooling system. When this component stops working, thick accumulations of steam begin to emerge from under the hood of the vehicle, a similar picture can often be seen in various films and TV series.

The thermostat mechanically transfers flows of cooled liquid at different temperatures through the cooling system. It works in a large circle when the engine overheats - passing through the radiator, and in a small circle when the engine is cold - bypassing it. If this part does not work correctly, then in the cold season the stove freezes and it is impossible to warm up the car interior. There is a thermostat in both a used car and a new one, if they use a closed version of the liquid cooling system with forced circulation of liquid at a low temperature. The principle of operation of the part is identical for all cars, regardless of the country of manufacture.

Diagnostic methods

With a properly functioning thermostat, the car engine heats up to operating temperature in 5-10 minutes at an ambient temperature of at least 0 degrees. If warming up takes longer, then it’s quite easy to verify that the thermostat is the culprit. To do this you need:

Start the engine and wait until the coolant temperature reading on the instrument panel is around 85 degrees.
Open the hood and find the pipe leading from the thermostat to the radiator. It should have approximately the same temperature as the rest of the cooling system pipes. If it is significantly colder, the valve is either closed or not fully open. This is a serious reason to replace the Lada-Priora thermostat.

Causes of malfunction

There can be any number of reasons why a thermostat fails, but the main, most common ones are:

scale;
corrosion;
dirt;
poor quality coolant;
spent resource.

Most often, the listed factors lead to the fact that not the entire thermostat fails, but its sensitive element, which is a sealed cylinder filled with a special wax-based mixture with a movable rod.

When heated, the mixture melts and expands, pushing the rod forward. This, in turn, pushes the valve, which closes and opens the pipeline. Corrosion, scale and dirt, settling on the moving parts of the thermostat (rod, valve), interfere with their normal operation, or even immobilize them.

What reasons can cause a malfunction in the thermostat?

The main reasons why a thermostat fails are pollutants. The latter get inside the cooling system during vehicle operation. It could be:

corrosion of metal;
various deposits and scale that are deposited on the inner walls of the thermoelement;
debris and dirt.

Over time, the amount of contaminants accumulates, which becomes an obstacle to the movement of the rod inside the cooling system.

To prevent this situation, you should monitor the quality of the antifreeze that is poured into the cooling system.

Signs of trouble

Even if you do not carry out diagnostics, you can suspect the presence of thermostat malfunctions during the operation of the car. They will manifest themselves as follows:

The engine takes a long time to warm up.
Heating the coolant to a temperature of 130 degrees and above.
The sensor shows the temperature during a stop is significantly higher than when driving at speed.
The lower thermostat pipe begins to warm up immediately after the engine starts. This indicates that the valve is not closing completely.
The lower pipe is cold when the temperature on the instrument panel approaches a hundred.

The last point reports a closed valve, except in the case when the cooling system fan is faulty, which does not require replacing the Priora thermostat.

Possible problems

Over time, the thermostat of a Priora car wears out and can be damaged. Since every time the car is started it is put into operation, the more often the car is in working condition, the more it is susceptible to breakdowns. As a result, it stops changing position and, in a broken state, takes either an open or closed position. This can be affected by mechanical damage, as well as loss of thermostat properties when the device ceases to control the temperature. It is possible that the valve will not close completely due to damage to the rubber gaskets. It is dangerous to operate such a car, so if it breaks down, it is recommended to replace the thermostat on the Priora with a new one.

The Lada Priora has 16 valves; when the device is not working, the following symptoms are noticeable on the car:

When the internal combustion engine constantly overheats, although the device is operating in normal mode, it is possible that the coolant is not passing through the radiator.

Due to coolant leakage, the device stops responding to temperature changes, and because of this, the engine will take much longer to warm up. If coolant gets on the element responsible for temperature control, the valve will open a little earlier and because of this there will be an oversupply. Thus, the cooling system may break down, and the engine will operate at higher speeds.

If the internal combustion engine starts to stall, then due to constant vibrations the coolant can come out and because of this the valve stops functioning.

Repair and replacement of heating faucet

If, in fact, it turns out that the stove on the Priora has stopped functioning as it should due to an inoperative faucet, the car owner will have to replace the failed structural element. To do this, consider a detailed and very accessible step-by-step plan for replacing the above part.

As for the necessary tools, the motorist will only need a 10mm socket and a wrench. After everything is ready, you should begin to implement the idea, initially ridding the cooling system of the power unit of the antifreeze contained in it.

Then it is necessary to dismantle the glove boxes on the Priora, in addition to removing the luggage rack. Only after carrying out all the steps described above, even an amateur motorist will be able to independently replace the heater tap.

The next step is to loosen the clamps that secure the heating system hoses. It should be noted that all these parts are located directly in the engine compartment. The motorist will have to disconnect the hoses and pipes of the heater tap

Before starting this process, it is important to mark the location of the pipes to be removed. In exactly the same way, you should disconnect the hoses that come from the heater faucet in the car interior.

Having completed these steps, the novice mechanic will see the area where the Priora stove faucet is located and will be able to independently unscrew both nuts responsible for fastening the structural element being replaced. Then you can begin to remove the heater tap, while working on the cable tension. It is imperative to remove the bracket and remove the cable that is connected to the crane lever. Only these actions will help you remove and change the tap of the heating device. At this stage, we can consider that half of the actions are over. All that remains is to get rid of the rubber seals and install the new stove faucet back in the reverse order of its removal.

How to solve a problem

Depending on the terrain in which the car is operated, it is necessary to choose which device is best to install on the Priora. If the installed device is suitable according to its parameters and characteristics, but the coolant exceeds the permissible values, then it is recommended to replace it with a similar spare part that has a higher temperature threshold for opening the valve. This approach is recommended for those who drive in mountainous areas or forests.

It happens that antifreeze stagnates in one place and this causes a plug to form. In this case, it is necessary to break through it. This can be done using a regular screwdriver.

If the valve opens prematurely, it is possible that the spring on the thermostat is weakened. In this case, you can tighten it or replace it with a new one.

When warming up the engine for a long time, it is best to check the rubber bands first. It is possible that the device is locked in the wrong position and will need to be secured in the correct position to normalize the air valve.

If the valve functions normally and opens on time, but the engine constantly overheats, then you first need to check the antifreeze level, as well as the possibility of plugging due to stagnation. It is possible that the radiator has stopped performing its functional duties and will need to be replaced. The problem may also lie in the fan or cooling pump. It is necessary to check their functionality and replace if necessary. The last thing that can interfere with good cooling is a dirty system. In this case, it is necessary to clean it.

Weight matters

A car disk is a simple flywheel mounted on a hub. To set it in motion, you need to expend a certain amount of energy, the source of which is fuel. And the greater the mass of the wheel, the more fuel will be required to spin it. But it is much more difficult to stop the wheel when its rotation speed is very high. At that moment, a very large load is placed on the braking system. Therefore, not only the comfort and controllability of the car, but also the safety of passengers in the cabin depends on the quality of the disc and the materials used to make it.

Modern wheels are made of steel and various light alloys, which give them a number of advantages:

Welded steel disc. This is a familiar stamped version that boasts a low price and durability. It is these discs that have the heaviest weight, are easily deformed and are more susceptible to corrosion than others. But with all their shortcomings, they are not so bad - if after falling into a hole the disk is dented, this can be quickly corrected at a service station.
Alloy wheels (cast and forged). They have much lighter weight, high anti-corrosion and strength properties and many design solutions. But they are already much more expensive. When subjected to strong impacts, alloy wheels do not bend like steel wheels, but rather crack. Forged ones can withstand the strongest blows and are practically impossible to bend.

DIY replacement

Before doing the work, you need to understand whether there are any differences in replacing the thermostat on a Priora with 16 valves from the same model with 8 valves. Despite the difference in power, the differences in engines are not significant. Both are based on the same cylinder block. Only the cylinder head and the gas distribution mechanism differ, and the unit itself, in which the division into small and large circles occurs, is the same. This means that replacing the thermostat on a Priora 16 cl is no different, except that you need to remove the decorative plastic cover covering the engine.

To change the thermostat you need:

Drain antifreeze from the radiator. To do this, unscrew the tap at the bottom and also remove the plug from the expansion tank. The container for draining must be prepared at least 5 liters.
Unscrew the clamp of the pipe going to the radiator and pull it off. A little more coolant will leak out, so you need to place a bottle to drain it.
Remove the opposite pipe in the same way.
Remove the 3 thermostat bolts using a hex wrench.
Move the rubber sealing ring from the old thermostat to the new one, lubricate the adjacent surfaces with silicone sealant.
Install the new thermostat and tighten the bolts.
Place the pipes in place, having previously lubricated the seats on the thermostat with silicone sealant.

Replacing the thermostat

To replace, you will need to drain the coolant.

Care must be taken to carry out work only on a cold engine to avoid burns.

Replacement Tool:

Head or key set to “13”;
Coolant 5 l;
Clamps 50 mm;
Hexagon on "6"
Screwdriver “+” and “-”

Work process

We remove the air filter box by unscrewing the clamp from the MAF sensor with a screwdriver and removing the chip from it. The box is held on by rubber clamps; in order for the box to be removed, you must forcefully pull it up.

Drain the coolant. To do this, use your head or a key set to “13” to unscrew the plug on the cylinder block and drain the liquid into a container.

You can use old fluid only if it is clean; it is not recommended to refill dirty coolant.

Loosen the front clamp of the large circle pipe on the thermostat cover (lower pipe from the radiator) and remove it.

Loosen the rear clamp of the pipe on the thermostat cover (from the water pump tube) and remove it.

Unscrew the 3 bolts securing the thermostat cover to the body with a hexagon to “6” and remove it.

Install the new thermostat cover in reverse order.

If the pipes are still old, it is recommended to use sealant to avoid coolant leaks.

After assembly, fill in the coolant, start the engine and let the car run for a few minutes, after which we check the coolant level again. Top up if necessary.

The thermostat replacement process is complete, there is nothing complicated about it.

Replacement

1. Place the car on a pit or overpass. Raise the hood and open the expansion tank cap.

2.Climb under the car and remove the engine protection. On the cylinder block we find a plug for draining the coolant in the form of a 13 bolt, it is located in the same place as on the 8-valve engine, well, due to inaccessibility from above, it is impossible to crawl up from above.

Replacing the thermostat on a Priora: instructions for the driver

“Lada-Priora” is one of the cars of the “VAZ” family. And as a typical representative, he is not without some shortcomings that arise at the most inopportune moment. Insufficient engine heating in winter or overheating in summer heat while stuck in a traffic jam - all this can be caused by a malfunction of the cooling system.

Replacing the thermostat on a Priora is an easy task for any motorist.

Purpose of the thermostat

This small detail makes a huge difference. It is the thermostat that allows the engine to operate at the optimal temperature. Being part of the cooling system, it acts as a valve that does not allow coolant to circulate in a large circle (through the radiator) until it reaches operating temperature.

The cooling system has 2 circuits that are connected to each other through a thermostat. A small circle allows you to warm up the engine as quickly as possible in cold weather. Until the coolant temperature rises to 70-75 degrees, the thermostat is completely closed. It begins to open slightly in this thermal gap and is fully open when it reaches 95 degrees.

As the valve opens, hot coolant is mixed into a large circle, where it passes through the radiator and releases some of the heat into the atmosphere. If the operating mode is violated, the Priora thermostat should be replaced.

Reasons for failure

The operation of the thermostat largely depends on how well it is assembled. If a high-quality part is installed on the car, and the owner uses good antifreeze and changes it in a timely manner, then the thermostat can last the entire life of the car.

Unfortunately, the coolant does not always comply with GOST, and parts supplied to the conveyor undergo quality control. All this leads to the fact that replacing the thermostat on a Priora becomes inevitable.

The main reasons for failure are the following:

Depressurization of the brass flask in which the wax is sealed. During operation, brass solder undergoes corrosion, as a result of which its integrity is compromised. This malfunction manifests itself in the fact that the valve opens completely, but is unable to close back. Antifreeze constantly passes in a large circle, and the engine cannot warm up to operating temperature.
Foreign particles entering the thermostat. This happens if the coolant has not been changed for a long time, and has also been diluted with water, and scale has formed. In this case, the valve may become stuck in both the open and closed positions. In the first case, warming up will take longer than usual, and in the second, the internal combustion engine will overheat.

Diagnostic methods

Start the engine and wait until the coolant temperature reading on the instrument panel is around 85 degrees.
Open the hood and find the pipe leading from the thermostat to the radiator. It should have approximately the same temperature as the rest of the cooling system pipes. If it is significantly colder, the valve is either closed or not fully open. This is a serious reason to replace the Lada-Priora thermostat.

Signs of trouble

Even if you do not carry out diagnostics, you can suspect the presence of thermostat malfunctions during the operation of the car. They will manifest themselves as follows:

The engine takes a long time to warm up.
Heating the coolant to a temperature of 130 degrees and above.
The sensor shows the temperature during a stop is significantly higher than when driving at speed.
The lower thermostat pipe begins to warm up immediately after the engine starts. This indicates that the valve is not closing completely.
The lower pipe is cold when the temperature on the instrument panel approaches a hundred.

The last point reports a closed valve, except in the case when the cooling system fan is faulty, which does not require replacing the Priora thermostat.

DIY replacement

To change the thermostat you need:

Drain antifreeze from the radiator. To do this, unscrew the tap at the bottom and also remove the plug from the expansion tank. The container for draining must be prepared at least 5 liters.
Unscrew the clamp of the pipe going to the radiator and pull it off. A little more coolant will leak out, so you need to place a bottle to drain it.
Remove the opposite pipe in the same way.
Remove the 3 thermostat bolts using a hex wrench.
Move the rubber sealing ring from the old thermostat to the new one, lubricate the adjacent surfaces with silicone sealant.
Install the new thermostat and tighten the bolts.
Place the pipes in place, having previously lubricated the seats on the thermostat with silicone sealant.

Additional Tips

Before replacing the Priora thermostat, it makes sense to check the new one for functionality. To do this, the part is placed in a pan of water.

As you gradually heat the water, you need to watch how the valve opens. If it is completely open at a temperature close to boiling, then it can be installed on the machine.

After replacement, remember to add antifreeze to the cooling system to the operating level indicated on the expansion tank. If a certain amount of coolant was spilled during draining, then you need to add the same color as the main fluid. Antifreezes of different colors do not mix.

Additional Tips

Before replacing the Priora thermostat, it makes sense to check the new one for functionality. To do this, the part is placed in a pan of water.

As you gradually heat the water, you need to watch how the valve opens. If it is completely open at a temperature close to boiling, then it can be installed on the machine.

In order for the Lada Priora 16 valves, and any other car model, to work properly and not let the driver down on the road, the car owner must monitor the technical serviceability of the car and promptly repair any breakdowns. If during the next check an antifreeze leak is detected, then you need to first check the thermostat, which will most likely have to be removed and replaced. Replacing a thermostat on a Priora is not a difficult task, so every car owner can cope with such a task, if, of course, this process is carried out according to the instructions provided by professionals in their field.

How to quickly determine that the thermostat on a Priora is faulty?

1. Warm up the engine slightly (to about 85 degrees).

2. Open the hood. Carefully touch the radiator hose at the bottom. A cold pipe indicates that the thermostat is working properly. The liquid does not flow to the radiator at this temperature, since the Priora’s thermostat is still closed. If the pipe is hot already at 80 degrees, this indicates a malfunction.

3. Now give the engine a good run.

4. Locate the radiator hoses. They are black rubber, about 5 cm in diameter.

5. Touch them carefully (you may get burned). If any of them are cold, it means that the thermostat on your Priora car simply does not work and requires replacement.

Choosing new thermostats for cars

Since the cost of a thermostat is usually not very high, and it is responsible for the performance of an expensive engine, it is better to change it every two years.

Today you can find several types of such devices on the specialized market. The most primitive are mechanical devices. But an electronic thermostat for a car controls the temperature using a special sensor.

There are also electromechanical units that operate using contact pairs.

When choosing a thermostat, it is very important to know its temperature regime, since it differs for different brands of cars. And, of course, it is necessary to select the device only strictly according to this parameter.

Thus, thermostats for cars can be high-temperature, operating in the range of 300–1200 °C. The valve opening for medium-temperature devices occurs in the range of 60–500 °C.

There are also low-temperature devices with an operating temperature of less than 60 °C.

Replacing the thermostat on a Priora - how to spend less than an hour?

To check the functionality of the thermostat, you need to warm up the engine and turn off the ignition. After this, open the hood and find two hoses there that are connected to the radiator.

We touch them with our hand and look at the temperature sensor readings. If the latter shows that the engine is hot, while at least one of the hoses remains cold, then the “temperature guard” needs to be replaced.

To do this, you need to read the information on how to remove the thermostat.

First of all, the cap on the radiator is unscrewed and the liquid is drained from the cooling system. Then, after loosening the clamps, you need to dismantle the water pipes that go to the thermostat. After unscrewing the mounting bolts, you can remove the device itself.

Now we open its cover and, pressing the spring with pliers, pull out the sensitive element and replace it with a new one. In addition, the rubber gasket also needs to be replaced.

Now you don't know how to properly install the thermostat? But there is nothing complicated in this operation, you just need to act strictly in the reverse order.

Self-replacement of the thermostat on Lada Priora

How to replace a Lada Priora thermostat

The need to remove or change the thermostat on the Lada Priora is caused by its malfunction or the appearance of antifreeze leaks. One of the signs of a thermostat malfunction is also the engine taking a long time to warm up.

The reason for this is that the thermostat does not close the large circulation circle of the cooling system, which leads to a double increase in fuel growth when warming up a cold engine.

Or, as an option, the thermostat, on the contrary, does not open a large circle, the temperature rises to a critical level, and the engine overheats.

Causes of thermostat malfunctions

The main cause of thermostat breakdowns is corrosion, scale, and dirt that forms in the cooling system during operation. The thermoelement becomes less sensitive to changes in coolant temperature due to rust and scale particles accumulating on it.

In addition, this complicates the movement of the rod that closes and opens the small and large circles of the cooling system. To avoid such defects, you should use good antifreeze and monitor its condition. At the time of replacement, you should check the bottom for the presence of rust particles and plaque.

You can read about how to flush if there are foreign substances in the antifreeze in this article.

Checking the thermostat on Lada Priora

To confirm or refute a thermostat malfunction, it is worth performing the following test.

We start the engine and warm it up to an operating temperature of 85-90 degrees.
In this case, the lower radiator pipe should not heat up.

The explanation for this is that the thermostat valve is closed, so coolant does not move through the pipe. Thanks to this, the engine warms up quickly, since the coolant circulates only in a small circle.

When the antifreeze reaches the desired temperature, the valve opens, freeing access to a large circle for the circulation of coolant. As soon as the valve opens, the liquid will flow in a large circle, so the lower pipe will heat up.

If the pipe becomes hot even at a temperature of 70-80 degrees, then the thermostat needs to be replaced.

Attention!

Sometimes lack of coolant circulation is the cause of a faulty water pump, so checking it is also necessary. You can see how to do this here and here.

Let's consider the principle of its operation and the main causes of breakdowns. So, how to remove and check the Lada Priora heater damper. The video will tell you how to remove the heater radiator on a VAZ car without removing the dashboard, and will also tell you about the nuances and subtleties of the process. When the cooling system operates, deposits accumulate in the engine block itself over time, which are then spread throughout the entire system, including into the heater radiator. In this case, the heater radiator can be replaced entirely. Before starting work, be sure to drain the antifreeze from the cooling system. After this, disassemble the stove body, disconnect the wires, remove the fan motor along with the impeller and remove the heat exchanger, disconnecting the supply hoses from it.

Many people guess what a heater radiator is for the Priora cooling system, but everyone knows for sure. The people for this heater have their own name: stove radiator.

What is the best thermostat to install on Priora - analogues

A regular retail parts store can offer analogues of the thermostat for Priora from the following manufacturers:

Stellox;
luzar;
Gallant;
FENOX.

In the question of which part is better to choose, it is hardly possible to compare analogues - they differ in quality. When asking drivers what thermostat is installed in their car, the most common answer is that only the original one is installed. It’s easier to trust the manufacturing plant - they know what they’re dealing with.

Replacing the Priora thermostat is required if the following symptoms occur:

Unfavorable factors such as dirt in the coolant, scale, corrosion and metal flakes can cause the moving parts of the valve to stop working properly. It may also jam. The following signs may indicate this:

• The coolant temperature rises to operating level too slowly, taking longer than 10 minutes. This makes it clear that the valve is always open. Therefore, the coolant, circulating in a circle through the radiator, does not allow the engine to warm up.

• The engine heats up quickly, but the temperature becomes critical. This happens when the valve is closed, blocking the flow of coolant to the radiator.

Therefore, when choosing which thermostat is best for a Priora, do not forget about the coolant. It must be clean and of good quality.

Which thermostat is better to install on Priora

In order not to be tormented by the question of whether it will fit or not, it is much better to buy a standard Priora thermostat, the catalog number of which is 21082-1306010-10. Various analogues should not be used.

As a last resort, you can take a VAZ branded part from other car models. Check with the store that you are choosing a thermostat for a Priora. An experienced sales consultant will tell you which one is better.

In addition, the correct choice will be facilitated by knowing at what temperature the thermostat on the Priora opens. Starting to open at 83 degrees, the rod fully opens at 102 degrees Celsius. Take this into account when deciding which thermostat is best for the Priora if you decide to install something different.

The standard thermostat of the VAZ 2170 Priora has catalog number 21082-1306010-10. When replacing, it is best to use a branded VAZ part, bypassing various types of analogues. As an alternative, you can use thermostats for other VAZ models with the following catalog numbers:

How to check for functionality

If all the described actions are not enough to determine the condition of the part, you can resort to experiment. As written earlier, to start working the part you need to feel the temperature of about 93-95 degrees. Why not replace the coolant with water?

The experiment can be carried out anywhere there is a kettle. After pouring approximately 300 ml of boiling water into a cup, you will have to wait 2 minutes, and then lower the “test person” into hot water. If it is working, then you can clearly study the principle of its operation. The rod of the part will begin a kind of movement, and the valve will rise to open the fluid communication through the large cycle.

Replacing the thermostat is not the easiest repair operation, but it is necessary so as not to “boil” in a traffic jam. It all depends on the choice of part and priorities. If you are too lazy to change it on time, engine wear will increase and, accordingly, its life will decrease.
