Thermostat on Priora 16 valves Which one is better. What thermostats are there according to the temperature on the Priora?

Hi all! Avno has not written anything since the study session is approaching and. etc. I’ll tell you how they tortured me, I’ve already changed the thermostats 5 times, then on the large circle it jammed (does not heat up) then on the small one (it boils). The last thermos is stuck on a large circle and with the onset of cold weather in the car there is no way (it heats up all day) to turn on the oven, the temperature drops below 70.

And when you drive, so does your silence. I started collecting information about shopping at the store, comparing thermostats, and all my thoughts on how to do it better. I didn’t want to install a potama at the factory because there are a lot of connections (and the more there are, the more likely it is to leak somewhere). I wanted to install one from a viburnum (the smallest of the VAZ ones), but there, in my opinion, I need welds so that the expansion barrels can be it was possible to connect where I wanted... And welding would only take place in 2 weeks.

And I don’t like to wait and I don’t have time (it’s not cold in the car, but I have to drive). Then I took a closer look at the Priorov thermos (in principle, nothing like that) and there were no alterations. In general, I don’t like the cooling and heating system of the VAZ (huh. Full!) It always boils, so the air is not blown out, if the coolant is gone, for which the stove does not heat up well, you can give a thousand examples.

The idea is to install a thermos from a Soviet car (after all, Gineal is the simplest and easiest to use), and that’s exactly how it is on that car. If the fastenings are the same with the can, I’ll try to do it again and then I’ll write about it (well, that’s next time) - thermostat (385 rub.) (Prioress, 10.8 new sample) 6 sockets on a thermos - Alaska antifreeze 3 liters ((220 rub. ) there was antifreeze and leave it alone) - thermostat gasket (from 2-4 rubles) (place between the engine and the thermos) - pint of the Prior thermostat 2 pcs. Just in case (size M8 * 45), well, in general there is one short lower one, and another M8 * 45 upper one - expansion tube from VAZ 2112 (factory short, rigid and without thread, and from 12 - soft in thickness and thread layer, everything is suitable perfect) in principle, it’s not difficult to put everything in place.

Here I will tell you how I drained the antifreeze (the garage is not my floor, they said not the bag), but over time he needed to figure out how to drain it. And the first thing that came to my mind was that everything went fine, but the thermos tube on the stove did not want to fly out, I reported this with a screwdriver and it began to peel off like the bark of a tree shorter than the khan for it (Buy a REPLACEMENT, just in case), FROM A FRIEND I DID NOT BUY. IN THE MACHINE OF LUCK)))) I took everything apart, cleaned the space for the gasket, changed the stud, since mine came out, and it was all rusty. Lubricate the gasket area on the engine and thermos with a thin layer of lithol (a good remedy for leaks in some cases is better than sealant) and screw the thermos.

The pipe that goes to the radiator fits perfectly, but the little one from the radiator is a bit short, so he puts it on and holds it, I don’t think there will be anything bad. The pipe that goes from the thermos to the suction pipe of the pump fits yours perfectly! it all depends on the tube itself, I have a bend and straight lines and there is no need to change the tube. Then I insert the expander tube, cutting off the handle by about 5-10 centimeters (you need to look at the place) and finally the chimney, I’ll tell you, crap, these are plastic seeds! hard! wireless, I personally didn’t like it, well, there was no choice, since it was night and there was nowhere to get a replacement for the factory one. I collected everything, filled it with antifreeze and started it up.

A car thermostat for Lada Priora is a very small part that makes a big contribution to maintaining the temperature in the car. No matter how hot a car engine gets, its purpose is to reduce the temperature by circulating fluid. The price of a standard thermostat is low; as a rule, it costs about 500+ rubles. Replacing the Lada Priora car thermostat is a mandatory procedure if the car warms up. In this case, it is necessary to change the thermostat, otherwise the engine will overheat. The part has analogues, but the standard part is most effective. The Priora has 16 valves, replacement is a little more difficult, given that it is difficult to get to the antifreeze drain plug. The Priora's thermostat saves the engine from overheating. The part comes in 2 types: 1 - opens at a temperature of 92 degrees, 2 - at 95.

The thermostat on the Priora is a very simple device: very often, as a rule, what is damaged is what is inside - the cylindrical sensitive element. It is filled with a wax-based substance and therefore can withstand room temperature well. The cylinder is wound around a spring, which is attached to a valve that tightly separates the small and large circulation circles of the cooling system. When the fluid in the cylinder reaches engine operating temperature, the spring expands and “pushes” the valve outward. But this does not happen immediately: the valve is fully extended only at a temperature of 103 degrees Celsius.

When the effect of liquid cooling is achieved, the temperature (already reduced) is transferred to the filling of the cylinder, after which the spring is slowly compressed and the valve is lowered. Thanks to the funnel effect, the coolant “drains” faster and its volume remains unchanged in a short cycle - this is how the cooling system is in working condition.

The thermostat on the Prioru is set at the factory with the expectation that the engine will only operate at the maximum permissible temperature. Its design is such that the thermostat (more precisely, its valve) is designed to open at a temperature of about 98 degrees Celsius. An open valve allows coolant to flow into the radiator, so that it cools even further - to an acceptable temperature - and circulates again, only now in a wide circle.

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.

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

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

2.7. Open the hood. Gently touch the bottom of the radiator hose. A cold pipe indicates that the thermostat is working. At this temperature, the liquid does not go into the radiator, because the Priora’s thermostat is still closed. On the contrary, the pipe is already heated to 80 degrees - this indicates a malfunction.

3. Now start the engine properly.

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

5. Touch them carefully (naturally burnt). If any of these apply, it means that the thermostat on your Priora is simply not working and needs to be replaced.

How to check the thermostat on Lada Priora?

In order to verify that the thermostat is faulty, you need to perform a small test to confirm or refute the assumption that the thermostat is faulty.

Start the engine and warm it up to operating temperature 85-90°.
Then touch the lower radiator hose, it should not be hot or warm, it should be completely cold.

This is explained by the fact that the thermostat valve is in a closed state, therefore no coolant circulates through the pipe. Actually, this allows the engine to warm up faster, the coolant circulates in a small circle and heats up the engine faster. After the antifreeze temperature reaches a certain temperature (95-100°), the valve gradually opens, opening a large circle for coolant circulation, in which the radiator begins to “participate”. After the valve is open and the liquid flows in a large circle, the lower pipe will begin to heat up, that is, it will be hot. If you find that this is not the case and the pipe is hot even at a temperature of 70-80°, the thermostat is faulty and requires replacement.

Note: Sometimes the lack of coolant circulation is due to a faulty water pump, so it would be a good idea to check that too. How to check the pump, read this article and this one.

To replace the thermostat on a Priora, you will need a minimum set of tools and clean coolant.

Principle of operation - how to determine that the thermostat on a Priora is not working

To check the thermostat, it is not necessary to connect to the system; look for the error code and watch its decoding. Everything is done the “old fashioned way”, and this method will in some sense be even more effective. If the following tools were required for the replacement: a 13mm wrench, a hexagon and a Phillips screwdriver, the next operation will require only your hands. The only thing you need to be careful with is that there is a high risk of getting burned.

The following algorithm will help you understand whether the thermostat is correct:

Start the engine and warm it up, wait until the temperature reaches 85-90 degrees Celsius. Raise the hood. Touch the bottom of the radiator. If the bottom of the radiator is cold, the cooling system operates as usual: when the valve is open, it means that liquid is circulating in a large circle. If it is believed that the pipe is already heated by 80 degrees, then circulation occurs in a small circle.

A working thermostat controls the valve in a timely manner: as soon as the temperature reaches the maximum permissible, it opens. And in this case, the thermostat valve is closed.

Now look for the injectors near the engine - if they get hot after a short warm-up, the thermostat may be at fault. But there is a problem: a faulty water pump can create an error in the system and may require replacement. If the suspicions are confirmed, you will have to spend your time on repairs: drain the coolant from the cooling system, climb under the overpass for it, then refill it and check the entire system several times, warming up the engine to 85 degrees. The work will not be done in vain - in no case should you “blindly” change a part of the cooling system, because it is subject to repair, and the water pump will remain under the hood and will still be the main culprit in overheating the car.

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.

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.

Examination

Since problems with the device can arise at any time, the driver needs to know how to check it even in situations where it is not possible to get to a car service center.

The easiest way to check the thermostat is to leave it on. To do this, the internal combustion engine must be cooled down. We start the engine and at this time we need to touch the pipe, which is attached to the radiator. During the first few minutes, the radiator is not yet functioning, so the pipe should be cool. After this, wait until the engine warms up to operating temperature. Next you need to check the same pipe, it should be heated.

If the tube remains cold, then it is worth looking at what thermostat is used and replacing it with a similar one.

If the pipe heats up almost immediately, the engine will operate at lower temperatures. This problem is not critical, but because of this, gasoline consumption increases.

There is also a second way to check the device by dismantling it.

Before dismantling, you need to drain the antifreeze into a pre-prepared canister. After this, remove the thermostat, which is installed behind the pipe. We take the device and put it in a pan of water and put it on gas. At the same time, it should not come into contact with the walls. We lower the thermometer into the water and wait for the water to heat up to the operating temperature of the motor. When the temperature readings reach the required value, make sure that the valve changes from the closed position to the open position. If this does not happen, it is recommended to install a new device.

Replacing the thermostat on a Priora is not a complicated process that does not require special skills and can be diagnosed at home using improvised methods.

To replace, we need a Phillips screwdriver and a 10mm wrench to loosen the clamps, a 5mm hexagon, a hose, a watering can, a 5 liter bottle to drain the antifreeze, and a 1 liter bottle when unscrewing the far pipe. The leak will come from two places.

To make it easier to carry out all manipulations, remove the air filter housing (AF), take a slotted screwdriver to remove and return the rubber bands to the attachment points of the air filter housing. Next, simply unscrew the fastening nuts.

Before installing a new thermostat, check it using the methods indicated above; assembly is carried out in the reverse order.

But for more accurate diagnostics, it is recommended to contact specialized service centers that will perform their work efficiently and provide a warranty period for them.

Causes of thermostat malfunction

Most often, the cause of thermostat failure is corrosion, scale and dirt that forms in the cooling system during operation. Particles of rust and scale are deposited on the thermoelement, as a result of which it loses sensitivity to changes in coolant temperature. Also, deposits interfere with the movement of the rod, which does not allow closing/opening the small/large circle in the cooling system. Therefore, in order to prevent such a scenario, fill in high-quality antifreeze and monitor its condition; during replacement, carefully inspect the bottom for the presence of “flakes” of rust or plaque. If the antifreeze is dirty, then the system requires flushing, as described here.

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.

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.

Correct selection and replacement of the thermostat on Priora

The cooling system of a car is one of the main systems that ensures the possibility of its operation. The thermostat, in turn, is its most important component, and its malfunction can sometimes lead to considerable costs.

How will replacing the thermostat on a Priora save the family budget? Everything is trivial - when this device does not work, the engine may overheat. All this increases wear on the motor and, as a result, will lead to serious damage.

The price of a thermostat for Priora is low. Therefore, it is better to change it every two years. Knowing how to change the thermostat on a Priora, it’s quite possible to do it yourself. However, there are some peculiarities. Therefore, it would not be superfluous to have a little theory in order to decide which thermostat for the Priora is better.

What is a thermostat on Priora

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

• 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.

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.

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.

How to replace a thermostat on a Priora

In order to successfully replace the thermostat in a Lada Priora car, you need to prepare. You should have clean coolant and tools on hand: a Phillips screwdriver, narrow-nose pliers and a five-point hex.

On a Priora car, the thermostat is replaced using the following algorithm:

1. Unscrew the cap on the radiator and drain the coolant.

2. To remove the Lada Priora thermostat, you will first have to loosen the clamps and disconnect the hoses that are attached to the thermostat cover.

3. Having previously unscrewed the bolts, remove the thermostat (Photo of the Priora and its engine compartment - see below).

4. Remove the thermostat cover bolts and pull it out.

5. Inspect the gasket located in the annular groove of the cover. If it is worn out, replace it.

6. Using pliers, pull out the mod. To do this, carefully clamp it, turn it and remove the fixing plate from the grooves.

7. We check the functionality of the new mod: heat it in a container with water. The pin should extend when the temperature reaches 90 degrees. Is this not happening? This means the mod is faulty.

8. We assemble the new thermostat in the reverse order. Do not forget to coat the joints of the pipes and the gasket on the cover with automotive sealant.

9. Pour clean antifreeze into the expansion flank of the engine up to about.

10. Warm up the engine, checking for leaks.

In the video, replacing the thermostat on a Priora is clearly shown.

The price of a Priora thermostat fluctuates around 500-1000 rubles. When choosing which thermostat is best for Priora, focus on workmanship, not cost. The new thermostat will allow the Lada Priora to delight you with uninterrupted operation.

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.

Winter thermostat

A thermostat that opens at 92°C appeared on store shelves quite recently, but managed to make a lot of noise. Its peculiarity is that engine operation at very low temperatures becomes more stable, fuel consumption decreases, and most importantly, the car’s stove begins to work much more efficiently and hotter.

As for the use of such a thermostat in the summer, this is a moot point. Since standing in traffic jams, the car is prone to the cooling fan operating more often. Therefore, its use in the summer is not recommended.

Changing the thermostat on a Lada Priora with your own hands

Replacing steering tips on a VAZ 2114Important for motorists to know

The need to remove or replace the thermostat on a Lada Priora usually arises if it malfunctions or an antifreeze leak occurs. Malfunctions in the thermostat can be detected by characteristic signs, for example, when the engine takes a long time to warm up.

This is due to the fact that the thermostat does not close the large circulation circle in the cooling system, as a result, the warm-up time of a cold engine doubles, and at the same time fuel consumption. Sometimes the opposite happens, the thermostat does not open a large circle and the engine temperature reaches a critical point, after which the engine overheats.

Causes of thermostat malfunction

How to check the thermostat on Lada Priora?

In order to verify that the thermostat is faulty, you need to perform a small test to confirm or refute the assumption that the thermostat is faulty.

Start the engine and warm it up to operating temperature 85-90°.
Then touch the lower radiator hose, it should not be hot or warm, it should be completely cold.

Note: Sometimes the lack of coolant circulation is due to a faulty water pump, so it would be a good idea to check that too. How to check the pump, read this article and this one.

To replace the thermostat on a Priora, you will need a minimum set of tools and clean coolant.

Do-it-yourself replacement of the Priora thermostat - instructions

1. First of all, drain the coolant from the cooling system; to do this, unscrew the cap on the radiator.

2. Loosen the clamps securing the water pipes going to the thermostat, then remove them completely.

3. Unscrew the thermostat mounting bolts, and then remove the thermostat.

4. Remove the cover from the housing; to do this, unscrew its fastening bolts.

5. Take out the rubber gasket; it is located in a small recess in the thermostat cover. Check its condition and replace it with a new one if necessary.

6. Take out the mod (sensitive element), to do this, use pliers to slightly squeeze and turn the spring, removing the fixing plate from the hook with the grooves.

7. Before installing a new mod, check it. To do this, lower it into water and start heating. As it heats up, at approximately 85-90°C, the thermostat rod should begin to move out; if this does not happen, replace the sensitive element.

Note: If you don’t want to “mess around” with disassembling the thermostat, you can replace it as an assembly, but this will be more expensive.

Now that the Lada Priora thermostat has been replaced, all that remains is to fill in clean antifreeze and assemble the tool. Upon completion of the work, start the engine and check how the thermostat works according to the instructions described above. Make sure there are no leaks.

which thermostat is better for Priora

Hello everyone! I haven’t written anything for a long time since the school session is coming soon. Etc. I’ll tell you how the thermostats tormented me; I’ve changed them 5 times already, sometimes on the large circle it jams (does not heat), then on the small one (boils). The last thermos jammed on a large circle and with the onset of cold weather it is not possible in the car (it heats up all day long) when you turn on the stove the temperature drops below 70.

And when driving like this, I’m silent. I started collecting information, going shopping, comparing thermostats and getting all my thoughts on what to do and how best to do it. The factory one didn’t want to install it because there are a lot of connections (and the more there are, the more likely it is that there will be a leak somewhere), I wanted to install it from the Kalina (the smallest of the VAZ ones), but according to my ideas, I need a drone welding to connect the expansion barrel where I wanted . And welding would only take place in 2 weeks.

But I don’t like to wait, and I don’t have time (it’s freezing, there’s no heat in the car, but I need to drive). Then I took a closer look at the Priorov thermos (in principle, nothing like that) and there were no alterations. In general, I don’t like the VAZ cooling and heating system (huh. It’s complete!) It’s always boiling, you can’t get the air out if the cooler is gone, for those whose stove doesn’t heat, well, you can give a thousand examples.

I initially thought of installing a thermos from a Soviet car (after all, everything that is natural is the simplest and easiest to use) and that’s exactly what it is on that car. If the fastenings there are the same with the VAZ, I’ll try to redo it again and then I’ll write about it (well, that’s next time) -thermostat (385 rubles) (Priora, 10.8 new model) 6 outlets on a thermos -Alaska antifreeze 3 liters ((220 rubles) there was antifreeze and let it be) -thermostat gasket (from 2-4 rubles) (placed between the engine and the thermos) -Prior thermostat studs 2 pcs. Just in case (size M8*45), well, there is generally one lower short one and another upper one M8*45 - the expansion barrel pipe from the VAZ 2112 (the factory one is short, hard and without threads, and from the 12th it is soft in thickness and one layer of threads , everything fits perfectly) so, in principle, it’s not difficult to install everything.

I’ll tell you how I drained the antifreeze (the garage is not my wooden floor, they said not a pack), but time passed and I needed to figure out how to drain it. And the first thing that came to mind was that everything was going fine, but the hose on the thermos on the stove didn’t want to come off, it stuck, I picked it up with a screwdriver and it started peeling off like the bark of a tree shorter than the khan (Buy a SPARE just in case), I DIDN’T BUY FROM A FRIEND, I ended up with IT'S LUCKY FOR ME IN THE CAR)))) I took it all apart, cleaned the place for the gasket, changed the stud since mine had come out and was all rusty. I smeared a thin layer of lithol on the space under the gasket on the engine and thermos (a good remedy for leaks in some cases is better than sealant) and screwed the thermos on.

The inlet pipe for the radiator fits perfectly, but the radiator itself is a little bit short, but it fits and stays on like this, I don’t think anything bad will happen. The pipe going from the thermos to the pump intake pipe fits perfectly! it all depends on the pipe itself; I have bent and straight ones, and I don’t need to change the pipe. Next, I installed the expander hose, cutting off 5-10 centimeters from it somewhere (you need to look on the spot) and lastly there was the stove pipe, I’ll tell you this is such crap, they are semi-plastic! tough! without threads, I personally didn’t like it, well, there was no choice, since it was night and there was nowhere to find a replacement for the factory one. I collected everything, filled it with antifreeze and started it.

And then the VENELLATOR JUST TURNED ON! I turned it off again, started it again, and it turned on again. In short, like 5 times, well, what did I come up with under the torpedo where the brains are, there are 3 relays and 3 relays, but I don’t know what is responsible, in general, on a stalled car, I took out the relays one by one and started it up, it turned out that the statret did not work (there is a starter relay and a relay for them) then gasoline. The pump did not pump (there is a relay for it and before) and the last relay for the fan. Then I put everything back in place and started it up and the fan didn’t work))) WHY THIS WAS HAPPENED I DON’T KNOW AND I DON’T KNOW THAT THE FAN NOW WORKS AT ALL AT HIGH TEMTERATURE! in general, right now the heater is blowing hot in position 3, the car warms up faster (if the engine does not warm up to the required temperature in this case, 90 and I had 70, fuel consumption increases because the engine speed is more than 1000 (there is a constant desire to warm up) the same as constantly driving leak! so I advise everyone whose temperature is not heating up to fix this! THANK YOU ALL! Source: https://www.drive2.ru.

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. We hope our article was useful to you.

Modification of the VAZ 2110 thermostat

If you decide to replace the thermostat with a new one, then at the same time you can immediately modify it

Modifying the thermostat has its pros and cons. In this article we will focus on how you can remake the VAZ 2110 thermostat yourself, and what you will need for this. Why are cars with a 6-hole thermostat warmer? They are warmer not because a sixth fitting has appeared there, but because the bypass channel has been reduced. And the new fitting serves to get rid of the constantly leaking heater return tee.

Comparison of bypass channels of a 6-hole thermostat - 11mm (left) and 5-hole - 16mm (right)

What does the bypass affect? Through the bypass channel, the coolant circulates in a small circle. And the smaller the diameter of the bypass channel, the more coolant flows through the heater. Since additional resistance is created when coolant flows in a small circle bypassing the stove. That is, by reducing the diameter of the bypass you increase the flow through the stove, that is, the car interior will be warmer.

Reducing the bypass channel for a 5-hole thermostat:

I would like to note right away that when the bypass channel in a 5-hole thermostat (TC) is narrowed, problems may arise: Problems associated with washing the thermoelement. That is, if in a 6-hole thermoelement the bypass coolant and the coolant of the outlet (cold) pipe of the stove are washed, then in a 5-hole thermocouple only the bypass coolant is washed. In order to reduce the bypass to the required value, you can cut a plate out of an aluminum plate. The plate must fit exactly inside , as shown in the figure. Next, the plate needs to be secured; for this you can use cold welding or rivets. Make sure that the rivets do not interfere with the closure of the small circle. Then we drill a new hole in the plate. Another fastening option.

Reducing the bypass channel for a 6-hole thermostat

Unlike the 5-hole TS, in the 6-hole TS I don’t see a single problem with narrowing the bypass! Because In addition to the bypass coolant, coolant from the heater also gets to the thermoelement. The technology for reducing the channel bypass is exactly the same here, except that we connect the heater return to the vehicle. For this fitting: What will be the difference after reducing the bypass? The difference will be that the temperature of the coolant reaching the thermoelement will depend on the percentage of coolant passing through the heater and passing directly through the bypass. And also from the drop in t in the heater radiator. If the drop in t in the heater radiator depends to a greater extent on the load on the radiator - the temperature of the outside air and the fan speed, respectively, then the percentage of the flows in question depends precisely on the diameter of the bypass. Accordingly, the stronger we If we reduce the bypass, the stronger will be the dependence of the engine t on the load on the stove.

Replacing the thermostat on a Priora - instructions

The replacement of the thermostat begins with the fact that the car must be driven onto an overpass. It’s easier to describe further steps step by step:

Open the hood, unscrew the cap (blue) of the expansion tank. Remove the engine protection;

Get down under the car. Find bolt 13 - this is a plug for draining the coolant. It is not surprising that it is more difficult to get to it on a sixteen-valve engine than on an eight-valve one - after all, the design has changed. Take your time to remove the plug;
Place a container (preferably a basin with a volume of at least 5 liters) under the plug, and only then unscrew it. Wait until all the antifreeze has drained, then tighten the bolt back. Check it several times, namely: tightness;
Go up the overpass, and under the hood, at the top right above the engine, find the required part on the cylinder head. Using a Phillips screwdriver, unscrew the screws of the clamps holding the pipes and remove them;
Using a hexagon, remove the thermostat cover bolts, and then the part itself. This element needs to be removed, but do not try to change the thermostat as quickly as possible - pay attention to the connection groove. It contains a rubber gasket, it can be cleaned of dirt and covered with automotive sealant;
After the work has been done, you can install a new part in place of the old one, tighten the cover bolts and finish the work - put the pipes on the part, tighten the clamps (you can even put on new ones), pour sealant into the joint between them;
Pour coolant into the reservoir. If a couple of days after the repair the machine consumes some liquid, this is normal - you just need to top it up to the normal level. Start the engine when warmed up (to about 75-80 degrees). At this time, check the integrity of the structure. Violation of tightness is unacceptable;
If everything is in order, all that remains is to put back the engine protection and close the hood;

Replacing a thermostat on a Priora with a 16-valve engine is a little more complicated than on a Priora with an eight-valve engine. But, nevertheless, it can introduce the car owner to the route to the nearest overpass or pit, which will help out more than once - no one can rule out a breakdown.

Causes of thermostat malfunctions on Priora

As soon as the first “bell” appears - the car begins to overheat and no action is taken from the cooling system - diagnostics begins. The following can interfere with the operation of the thermostat in a Priora with a 16-valve engine:

Dirt;
Age (all details have their own resource, and this must be remembered);
Rust;
Low quality coolant;
Scale.

If at least one of this list defeats a small part, the coolant heats up above 95 degrees, and the fan turns on, which tries to create a flow of cool air directed at the engine. The reasons why a thermostat fails are most often limited by the age of the part - you can forget to change it in time, and then stumble upon an unexpected repair.

Its service life does not always end at the end of its service life - if debris got into the thermocouple, it could contaminate the sensitive part of the part that reads the temperature of the coolant. The thermostat on the Priora with 16 valves is not infinite, and it should not be blamed for the fact that on a polluted rural road it failed earlier than expected.

Replacing the thermostat on a Priora

To perform the work you will need the following tools: — Key to “13”; — Screwdriver with a flat end; — Capacious container for liquid; - hex key.

First of all, we install the car on a lift, overpass or over a garage pit.
We move under the bottom of the car, remove the engine protection (if installed). On the block we find a drain plug made in the form of a “13” bolt. We prepare and place a deep sealed container under the drainage area. Using a wrench, unscrew the drain nut. We wait until all the liquid has drained. We tighten the bolt back.
Let's move on to the engine compartment. We find the unit we need. It is located directly under the air filter pipe. Using a screwdriver, unscrew the screws of the clamps for the two large pipes and pull them off the assembly.
We take the hexagon in our hands and unscrew the bolts securing the thermostat housing. We dismantle the product.
We install a new device to replace the old one. When installing, pay attention to the rubber sealing gasket, which should not have cracks or other damage.
We put on the pipes and tighten the clamps.
Pour coolant into the expansion tank.
Let's start the engine. We wait until the engine warms up to operating temperature and check the functionality of the system. The replacement procedure is the same for both 8-valve versions of cars and for 16-valve prior thermostats.

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.

3. Place a container with a volume of at least 5 liters under it and unscrew the bolt. We wait until all the liquid has drained. Tighten the bolt.

4.In the engine compartment we find the thermostat. It is located on the right side of the cylinder head, under the air filter pipe.

5. Using a screwdriver, loosen the screws of the clamps on the two large thermostat pipes and remove them.

6.Use a hex wrench to unscrew the thermostat mounting bolts and dismantle it.

7.Before installing the new part, pay attention to the rubber gasket in the connection groove. For better sealing, you can lubricate this gasket with automotive sealant.

8.Install the new thermostat into place and secure it with bolts.

9. We put on the pipes, clamp the clamps, having previously lubricated the joints with sealant.

We recommend: Replacing the thermostat Lada 2115 (VAZ 2115)

10.Fill with coolant. If its level decreases after repair, add more.

11.Start the engine, warm it up, and check the tightness of the connections.

12.Reinstall the engine protection.

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.

Replacing the thermostat on a Priora 16 valves - instructions, analogues

A car thermostat for Lada Priora is a very small part that makes a big contribution to maintaining the temperature of the car. No matter how hot the car engine gets, its goal is to reduce the temperature by circulating fluid. The price of a standard thermostat is not high; as a rule, it costs around 500+ rubles. Replacing the thermostat of a Lada Priora car is a mandatory procedure if the car gets hot. In this case, it is necessary to change the thermostat, otherwise the engine will overheat. The part has analogues, but the standard part is the most effective. The Prior has 16 valves, replacement is a little more difficult, due to the fact that it is difficult to get to the antifreeze drain cap. The thermostat of the Priora car saves the engine from overheating. The part comes in 2 types: 1 - opens at a temperature of 92 degrees, 2 - at 95.

The thermostat on the Priora is a very simple device - what is most often damaged is what is inside: the cylindrical sensitive element. It is filled with a wax-based substance and therefore takes the ambient temperature well. The cylinder is surrounded by a spring, which is attached to a valve that tightly separates the small and large circles of circulation of the cooling system. When the material in the cylinder warms up to engine operating temperature, the spring expands and “pushes” the valve out. But this does not happen immediately: the valve extends fully only at a temperature of 103 degrees Celsius.

When the cooling effect of the liquid is achieved, the temperature (already reduced) is transferred to the filling of the cylinder, after which the spring is slowly compressed and the valve moves down. Thanks to the funnel effect, the coolant “drains” faster, and its volume in a small cycle remains unchanged - this is how the cooling system works.

The thermostat on the Priora is installed at the factory with the expectation that the engine will operate exclusively within the maximum permissible temperature. Its design is such that the thermostat (or rather, its valve) is designed to open at a temperature of about 98 degrees Celsius. An open valve provides a path for coolant into the radiator so that it cools even more - to an acceptable temperature - and circulates again, only this time in a large circle.

The factory thermostat of Lada Priora looks like this

Standard part - article number, price

The thermostat for the Lada Priora car is produced not only by the Volzhsky Automobile Plant - there is

cheap analogues, not at all pleasing with quality and durability. Compared to them, the price of a thermostat on a Priora with a 16-valve engine is not very high - about 500 rubles.

Quite a few remain who adhere to the theory that even an analogue can be better than the original; the main thing is to search well. The article number for this part for Priora must contain the following numbers - 21082-1306010-10.

Principle of operation - how to determine that the thermostat on a Priora is not working

In order to check the thermostat, you do not need to connect to the system, look for the error code and look at its interpretation. Everything is done the “old fashioned way”, and this method will in some ways be even more effective. If the following tools were required for replacement: a 13 key, a hexagon and a Phillips screwdriver, then for the next operation only your hands will be needed. The only thing you have to be careful with is that there is a high risk of getting burned.

The following algorithm will help you understand whether the thermostat is correct:

Start the engine and warm it up, wait until the temperature is 85-90 degrees Celsius. Raise the hood. Touch the bottom of the radiator. If the bottom of the radiator is cold, then the cooling system operates as usual: when the valve is open, this means that the liquid circulates in a large circle. If you feel that the pipe is already hot at 80 degrees, then circulation occurs in a small circle.

A working thermostat controls the operation of the valve in a timely manner - as soon as the temperature reaches the maximum permissible, it opens. And in this case, the thermostat valve is in the closed state.

Now look near the engine for the pipes - if they get hot after a short warm-up, then the thermostat may be at fault. But there is a catch here: a faulty water pump can create an error in the system - it is possible that it needs to be replaced. If the suspicions turn out to be true, you will have to spend your time on repairs - drain the coolant from the cooling system, crawl under the overpass to do this, then fill it in again and check the entire system several times, warming up the engine to 85 degrees. The work will not be done in vain - in no case should you “blindly” change a part of the cooling system, because it may be working properly, but the water pump will remain under the hood and will still be the main culprit in overheating the car.

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.

Which thermostat is better to install on Priora

How to replace a thermostat on a Priora

On a Priora car, the thermostat is replaced using the following algorithm:

1. Unscrew the cap on the radiator and drain the coolant.

2. To remove the Lada Priora thermostat, you will first have to loosen the clamps and disconnect the hoses that are attached to the thermostat cover.

3. Having previously unscrewed the bolts, remove the thermostat (Photo of the Priora and its engine compartment - see below).

4. Remove the thermostat cover bolts and pull it out.

5. Inspect the gasket located in the annular groove of the cover. If it is worn out, replace it.

6. Using pliers, pull out the mod. To do this, carefully clamp it, turn it and remove the fixing plate from the grooves.

7. We check the functionality of the new mod: heat it in a container with water. The pin should extend when the temperature reaches 90 degrees. Is this not happening? This means the mod is faulty.

8. We assemble the new thermostat in the reverse order. Do not forget to coat the joints of the pipes and the gasket on the cover with automotive sealant.

9. Pour clean antifreeze into the expansion flank of the engine up to about.

10. Warm up the engine, checking for leaks.

How to replace a thermostat on a Priora

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.
