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.
Standard part - article number, price
The thermostat for the Lada Priora car is produced not only by the Volzhsky Automobile Plant - there is
economical analogues, not at all pleasant in terms of quality and durability. Compared to them, the price of a thermostat for a Priora with a 16-valve engine is not very high - about 500 rubles.
Many people adhere to the theory that even an analogue can be better than the original; the main thing is to look good. The article number of this part for Prioress must contain the following numbers - 21082-1306010-10.
Cost of replacement work
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:
- 21082-1306010-11;
- 21082-1306010-12;
- 21082-1306010-14;
- 21082-1306010-15.
The thermostat is supplied with a 5mm hex key.
To be sure that the purchased thermostat is working, it is recommended to test it in hot water using the method described above before installing it.
The cost of a thermostat for a VAZ 2170 is about 500 rubles. The price for replacing it at service stations varies from 500 to 800 rubles.
Causes of thermostat malfunctions on Priora
As soon as the first “bell” appears—the car begins to overheat and the cooling system does not intervene—diagnosis begins. Interfering with the operation of the thermostat on a Priora with a 16-valve engine can:
- Filthy;
- Age (all details have their own resource and you need to remember this);
- Rust;
- Low quality coolant;
- Ladder.
If one of these lists damages a small part, the coolant heats up above 95 degrees and the fan turns on and tries to create a direct flow of cold air to the engine. The reasons why a thermostat fails are often limited to the age of the part - you may forget to replace it on time and then be faced with unexpected repairs.
Its useful life does not always end at the end of its useful life: if debris gets into the thermocouple, it can contaminate the sensing part of the part that reads the coolant temperature. The Prioru's 16-valve thermostat doesn't last forever, and you can't blame it if it failed sooner than expected on a muddy country road.
What is the difference between the thermostats on the new and old Priora?
It is important to know that Priora produces old and new thermostats. Old-style products have 5 fittings and are produced with article number 21082-1306010-10. Such options were installed on early Prior models.
The thermostat on the new-style Priora has article numbers 21082-1306010-11 and 12. The difference between them is that the design of the old-style thermostat has 5 fittings for connection, and the design of the new model has 6. This feature made it possible to solve one of the most important problems of VAZ cars , which consists in slowly warming up the radiator of the stove. On thermostats with 6 terminals, the heater in the cabin begins to heat up much earlier than when using old-style thermostats.
Interesting! Some Priora car owners resort to installing thermostats from Grants.
Replacing the thermostat on a Priora - instructions
Replacing the thermostat begins with driving the car over 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 cover;
- Get hit by a car. Find bolt 13 - this is a plug for draining the coolant. It is not surprising that it is more difficult to crawl on a sixteen-valve engine than on an eight-valve one - the design has changed over time. Take your time to remove the plug;
- We place a container under the lid (preferably a basin with a volume of at least 5 liters) and only then unscrew it. Wait until all the antifreeze has drained, then retighten the bolt. Check 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 hex wrench, remove the thermostat cover bolts and then the part itself. This element must be removed, but do not try to change the thermostat as soon as possible - pay attention to the connection groove. There is 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 job - put the pipes on the part, tighten the clamps (new ones are also possible), fill the joint between them with sealant;
- Pour coolant into the reservoir. If a couple of days after the repair the machine has consumed a certain amount of liquid, this is normal: you just need to top it up to the normal level. Start the engine when warmed up (approximately 75-80 degrees). At this time, check the integrity of the structure. Breaking the seal is unacceptable;
- If everything is in order, all that remains is to put the engine cover back on and close the hood;
Replacing a thermostat on a 16-valve Priora engine is a little more difficult than on an eight-valve Priora engine. However, he can tell the car owner the route to the nearest overpass or pit, which will help more than once - no one can rule out a breakdown.
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.
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.
How to check the thermostat
You can understand that the thermostat has stopped functioning normally by the time the engine warms up. If the coolant does not heat up to a temperature of 90C within 5-10 minutes of engine operation, then it’s time to check the thermostat for functionality.
The opposite can also happen - the engine heats up quickly, but the temperature reaches critical levels. This indicates that the thermostat valve is constantly in the closed position.
There are two ways to check the thermostat. The first method does not require removing it from the engine. To check you need:
- start the engine;
- warm it up to operating temperature;
- raise the hood;
- Find the lower radiator hose and touch it.
If the pipe is cold, it means the thermostat has not worked. If it is hot (warm), the device operates in normal mode.
The second method will not only determine the functionality of the thermostat, but also clearly show its operation. To do this you need:
- remove its cover along with the sensitive element;
- put it in a metal bowl with water and put it on fire;
- heat to a temperature of 85-90 degrees.
The sensing element rod should move forward. If this does not happen before the water boils, the thermostat can be thrown away.
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 mentioned above, to start working on a part, you need to feel the temperature around 93-95 degrees. Why not replace the coolant with water?
The experiment can be carried out anywhere there is a kettle. After pouring about 300 ml of boiling water into a cup, you need to wait 2 minutes, then lower the “object” into hot water. If it is working, then you can clearly study the principle of its operation. The stem of the part will begin to move in a peculiar way, and the valve will rise, opening the fluid communication in a 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, as a result, its service life will be reduced.
Correct selection and replacement of the thermostat on Priora
The cooling system of a car is one of the main systems that makes it possible to operate. The thermostat, again, is an important component and failure can sometimes be costly.
How will replacing the Priora thermostat save the family budget? Our client remains to do routine work: if this device fails, the engine may overheat. Everything increases engine wear, which means it will lead to serious damage.
The cost of the Priora thermostat is low. Therefore, it is best to change it every two years. Knowing how to change the thermostat on a Priora, this can be done at home. But it has its own characteristics. The theory will be a little superfluous to determine which thermostat from Priora is better.
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.
What is a thermostat on Priora
The Prioru thermostat is the main sensitive element 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 at the same time: bypass and main.
Usually, if the main valve on a Priora malfunctions, it is necessary to replace the thermostat. It has a cylinder 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. The valve then opens. On the contrary, after hardening the wax becomes miniature in volume. The valve closes. For a Priora car, the thermostat is shown in the photo in the section. Its device is shown.
KEY-DOP
The uninterrupted operation of the Priora thermostat maintains the engine temperature at normal operating levels. When the engine warms up, the Priora thermostat valve closes, the opening temperature of which is 90-95 degrees. As a result, no coolant flows to the radiator. System temperatures rise faster, engine wear and exhaust emissions are reduced, and time and fuel are saved.
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.
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.
Which thermostat is better to install on Priora
In order not to suffer from demand, it won’t work any other way, a very ideal option is to buy a Priora thermostat with a standard one, the catalog number of which is 21082-1306010-10. It is harmful to use different analogues.
In the latter case, it is possible to take part of the VAZ brand from other car models. Check with the store that you are choosing a thermostat for a Priora. What's better: An experienced salesperson will tip you.
KEY-DOP
Now it will be easier to make the right choice, knowing at what temperature the thermostat on the Prioress opens. Begins to open at 83 degrees, the stem opens fully at 102 degrees Celsius. Keep this in mind when deciding which thermostat is best for the Priora if you decide to install something else.
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:
- Constant engine overheating;
- Untimely opening of the valve;
- The internal combustion engine takes longer to heat up;
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 replace a thermostat on a Priora
To change the thermostat in a Lada Priora car successfully, you need to prepare. You should have clean coolant and tools: a Phillips screwdriver, pliers, and a 5-bit Allen key.
Read
On a Priora car, replacing the thermostat is carried out in the following way:
1. Unscrew the cap on the radiator and drain the coolant.
3.5. To remove the Lada Priora thermostat, you must first loosen the clamps and disconnect the pipes 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. Unscrew the thermostat cover bolts and remove it.
5. Inspect the gasket in the groove under the cover ring. If it's on, change it.
6. Use pliers to remove the mod. To do this, carefully secure it to yourself, turn it and pull the fixing plate out of the grooves.
7. Check the operation of the new mod: warm it up in a container with water. The pin should come out when the temperature reaches 90 degrees. Isn't this happening? This means the mod is faulty.
8. Reassemble the new thermostat in the reverse order. Don't forget to lubricate the car with sealant, the pipes and the gasket on the cover.
