how does your modification work? does not jam if the stove valve is closed during the first start-up and warm-up (respectively). I don’t understand anyway.

please tell me the tee is from what car?

Strange. I have everything stock. It's so hot that the plastic of the blowers has melted. 0_0 

the author is a moron on earth, so it should be, she shouldn’t be heated up by the earth, that is, 87-90 degrees, you motherfucker.

I have an 8ka 85, so after 10 km it’s impossible to sit in the car.

I don’t understand a damn thing, coolant should go straight from the lower pipe directly to the pump, but where to the radiator? And this immediately turns out to be a big circle. 

I did it on my 21083 https://www.drive2.ru/r/lada/992734/ a long time ago, only advantages, I threw out the faucet altogether, installed an electric faucet from the Gazelle Business under the hood and a button in the cabin, it heats up instantly, the stove definitely fries, in the summer, when the tap is switched to bypass, the stove is generally cold, etc.

what's the tee from?

But how does the coolant flow in a large circle? Does it go through the heater radiator and through the upper pipe?

Is it worth it with a 10 thermos 6 holes? Is it worth installing a Grant one? +is there? 

The author didn’t say a word about the stove tap! With such a system it should ALWAYS be open! 

I like the author for his ingenuity. The air intake flap from outside the radiator does not close tightly. Glue it with foam rubber and assemble the stove body with sealant, in general you will be driving in shorts in winter! 

Why is your voltmeter scaled like that? I also have a 9, also from 1988, but the needle is almost always on red, the voltage is somewhere around 13W 

Thanks to the author. I'm pleased with the result. The car became noticeably warmer. 

Well, I don’t know the author, the low panel (I own one myself) is actually hot in itself, I have a stock 09 98, the cooling system is also stock, so the car hasn’t warmed up to working temperature, but it’s already warm in the car, and then it’s Tashkent, Your problem most likely was something else, perhaps the stove radiator is clogged, or the interior is quite drafty, but as an option you can do it the way you did.

Good evening author, I have a question: does the thermostat from Granta go into place without any problems? There are no cracks or gaps between the engine and the thermostat. Can you still fit on heels without problems? 

where do you get the throttle heating?

Hi all. Why does hot air not flow into the cabin when the tap is open (always) in the summer? Or is there a message that it needs to be closed in the summer, but in the winter it is always open? I don’t understand something. Is it also possible to get the entire list of required spare parts for the conversion? Which pipe, which tee? Etc. 

Today I changed the thermostat - as shown in the video, so far I’m happy. I couldn’t find the tee, I soldered it myself from plastic tubes. Thank you very much to the author for the tuning.

At what temperature does it open? I heard that when installing a Grant thermostat, the engine will underheat, supposedly the thermoelement on this thermostat needs to be changed to 92 degrees. 

It would be cooler if, after the modification, you started it when it was cold and took off how much it heats up to the maximum temperature

Tell me, will this fit on the 21099 injector?

But what about in the summer when the heater tap is closed? The thermostat is also closed while it warms up. 

that means so, and the author has a problem with the heating system, the heat on my low panel on the standard thermostat is unbearable. It's most likely a leak in the heater when cold air is sucked in past the damper or the radiator heater is without swirlers inside. Grant's thermostat is good, but we must keep in mind that when we close the tap in the summer, we immediately overheat the engine, and driving in the heat with a heated radiator is brutal. Modern cars do not have a heater tap and the air flow is regulated by dampers; on new vases everything works very well with this thermostat. This won’t work in Samara; in summer the heater radiator should be cold 

So what will happen in the summer? If you close the stove in the cabin? Not a word about that. Most likely there will be a bomb in the tank)))))))) or am I wrong? Author, write about this in more detail! Or will the stock thermal be returned in the summer?

People, tell me why the engine on 9 takes so long to warm up? I changed the thermostats, installed my own ones, and a 10-point one. The lower pipe is always cold before the thermostat opens, and the engine doesn’t heat up at all. It's a 5 km drive to work. I warm it up in the garage for a couple of minutes, then drive along a flat road for 5 km. The engine barely heats up to 50. What could be the matter?? In the summer it's the same bullshit. Carlson almost never turns on. 

What happens if you turn off the stove tap?

Good afternoon, I have a question for you, I want to change the thermostat from Granti to nine if I put a tee at the output of the thermostat and connect the heater and gas reducer and go into the saxophone. If I close the stove tap, will the gearbox allow a large volume of liquid to pass through itself and nothing bad will happen to it? 

Everything is great for winter, but what about in summer with such a thermos?

I have a question. Since the small circle is a heater radiator, then all the coolant flows through it. Granta has a different radiator design. The question is: will the heater radiator cope with all the liquid pressure at maximum engine speed, if we say spin it up to 6000 rpm? 

It’s easier to buy a thermostat with a narrowed channel and that’s it. cheaper and more effective. 

Where is the tee from, I can’t find it

Maxim did everything according to your instructions and what did I get from it? (1) I freed up a lot of space under the distributor (which I am very pleased with). (2) My car never warmed up (previously, after driving 12 kilometers, warm air just started blowing), now It’s just Tashkent, even quite warm air blew from the side vents. (3) I turned off the heater tap because The faucet in 21099 is essentially not needed at all (extra hemorrhoids are like a goat's button accordion). (4) Instead of a plug where there should be a d.t. I installed a Grant one with 2 wires (one was connected to the wire from the original sensor and the second was immediately connected to ground to the top pin from the thermostat. (5) the stove after starting warms up to 92 degrees, in a Tashkent car and only then does the thermostat open, even with with the heater fan turned on, the temperature does not drop much. (6) While I was disconnecting the faucet cable, quite very hot air was blowing across my face. So there are only advantages. I just came up with an idea, if you put a tee in the hose that goes from the thermal to the heater, and connect it to this tee preheat the throttle, and turn off the throttle output from the return line (but that doesn’t really bother me). 

How to replace the thermostat on a VAZ-2109 with an 8 or 16 valve engine?

This operation should not cause difficulties, and any car owner should be able to handle it, regardless of his experience in the field of car repair. What actions need to be performed are described in this article. The thermostat is a mechanical unit; its operation is based on physical rules. Inside it is wax, which is sensitive to temperature changes. When the coolant is heated, the wax melts and a damper opens, allowing coolant to enter the system, where it is cooled.

Thermostat design VAZ 2109: 1 – inlet pipe from the radiator, 2 – rubber insert, 3 – solid heat-sensitive filler, 4 – bypass valve spring, 5 – inlet pipe from the engine, 6 – bypass valve, 7 – outlet pipe to the pump, 8 – main valve spring, 9 – main valve, 10 – pipe from the expansion tank, 11 – piston.

From the VAZ-2109 to the modern Granta model, thermostats perform their function adhering to one principle, and they are interchangeable with each other. The new unit is smaller in size than the old VAZ models; this fact will not interfere with installing the part from the old VAZ model.

To make the stove heat better, a thermostat from the new VAZ model is installed for this purpose.

Thermostat from grants for VAZ 2109 injector. This question: I installed a thermostat from grants for 2109

Hello！ Guys, here’s a question: I installed the thermostat from Granta at 2109. And everything seems to be fine, but summer is approaching, and you can’t turn off the stove tap, because there is a small circle through it. Maybe someone did something like this? How did you resolve the issue? PS carburetor engine.. Thermostat from grants for VAZ 2109 injector.

I did the same thing, I think I can save myself with a flap, but I don’t think it will help, I’ll have to farm with an intermediate pipe and a tap for the summer.

Take the pressure off him and that’s it. Only the air damper will work.

By the way, is it hot in your cabin or something, it seemed to be warmer for me, but a friend set it to 12; the air burned his hand, but mine didn’t.

If you completely muffle the river, remove the two hoses and connect them through the fitting

You open the damper when it’s cold and everything will be fine, no need to do anything collectively

Make a jumper on the half-turn tap in front of the stove tap, open the jumper, close the stove tap and that’s it

There you need to install an electronic valve with 3 inputs

Oleg, the hand endures, but it’s very hot

Sergey, what about the radiator? It will be constantly hot

Vitaly, I think it’s better not to come up with

If you open the damper, air will not flow through the radiator.

On the grant, the radiator is always hot, everything is fine, by the way, it depends on the pump (for the grant itself) with a metal impeller it is cooler

I've been driving a chepyrka like this for 6 years now.

Sergey, I heard somewhere that a heated radiator also fries well without any airflow

Sergei, I decided to redo everything then and installed a turbocharged pump

Doesn't fry anything

And it works fine on the original pump

Why don't you redo this thermostat from the IbatsCA grants! The Polish metal Incar at 87 degrees copes with its task quite well! At -40 we drove without any cardboard on the 99 high panel, and did not freeze, the only thing is that it partially tightens the glass. And so the DaAZ radiator, normal pump, faucet fully open and the damper is taped, there are no gaps. And also, when the crane was installing a new cable, I didn’t put a new cable on it. I moved it with my hand for the winter (opened it), closed it for the summer, otherwise I noticed that you jerk it back and forth, then it starts to leak and the valve in it fucks up

Nikita, my neighbor did this and he doesn’t know grief

Oleg, are there any air leaks anywhere? I just had the same problem

Nikolay, yes, most likely there is, I recently bought it and haven’t climbed it yet. I don’t have a garage, I’m waiting for the heat to spread the panel.

Oleg, well then look at the smallest pipes first, if not then iron the cylinder head

Thermostat diagnostics

It should be clarified that on a VAZ-2109 with any engine modification, when checking, it is not necessary to drain the coolant from the cooling system.
This operation is performed according to the following algorithm:

1. the engine starts;
2. The temperature is checked at the lower pipe that comes out of the radiator.

If the system is working properly, it should be cold, since the coolant should circulate only through a small circuit. The coolant heats up over time. When the coolant reaches a temperature ranging from 87 to 92 degrees, the wax inside the thermostat melts and the damper opens, as a result of which the liquid begins to circulate in a large circle. If this does not happen, then the thermostat is not functioning correctly and should be replaced with a working one.

Attention! To make sure that the thermostat is really not working, it should be lowered using a rag into water, the temperature of which is from 87 to 90 degrees. For a working unit, the main valve will be open.

Preparing for replacement

In order for the car to be completely ready to replace the thermostat, you need to wait until the engine cools down to at least 40-50 degrees. It is extremely dangerous to work while it is hot; you can get burned. The thermostat on a VAZ-2109 is replaced quite quickly; the most difficult and tedious procedure is emptying the system. To do this, you need to use two drain holes, which are located in the lower part of the radiator (the plug is unscrewed by hand) and in the engine block (head bolt 13).

But what should you do if the system is filled with antifreeze, which is quite expensive? We must try to preserve it so that it is not expensive to repair the car. To do this, first of all, by opening the stove tap, unscrew the clamp on the pipe that goes to the throttle valve. It is necessary to drain the maximum possible amount of antifreeze through it. Yes, this procedure is slow, but it will save almost all the liquid. Only after this can you unscrew the plug on the radiator and on the engine block. And don’t forget to unscrew the cap on the expansion tank to increase the pressure.

and how much are the tees, diameter? Tell me brotherly, I want to bet on 99.

Hey buddy, can you tell me how to install this thermostat on the Kalina on the Lada from Grantov

I don’t care where you put it, even on a tractor, the main thing is to understand its operation, the most important thing is that the heating valve needs to be installed in general, and if it’s not there, then everything is great

Are the studs 8mm by 100 or 80?

Where can I buy such a Tee? thick with thin output?

And how much did the spare parts cost?

90% of the sum is the thermostat. maximum 20$ for everything

Well, tell me the length of the studs, what are the tees, what are the diameters.

the part has a purpose (UAZ, GAZ.) has a catalog number, your words about hedgehogs and selection according to. they talk about the inability to convey complete information to the viewer, which makes your video dull and uninteresting and of little use. The tee requires an M22x1.5 fitting with an output of 18-20mm, such fittings do not exist in nature, you just have to sharpen them. I have already installed and: studs 2101 - camshaft, tee Code: 01_0408, or number 000132653 has a narrowing inside and is very bad for the summer, so they put it from UAZ 451-1303018-10, but with us this is rare and only to order and the price is the same thermostat. I made the tee myself from 32mm and 20mm pipes, 150mm long, with an angle of 70 degrees, because without extension you need to buy a 32mm pipe with an angle of 70 degrees. When a person goes to the store (calls), he already knows what he needs, and does not blow the minds of women who do not understand what they are talking about. When I order spare parts online, I need part numbers, and not the manager’s stupid orders to run to the warehouse and pick up studs and pipes for me.

Which Thermostat is Better to Install on a VAZ 2115

Not only the engine temperature affects the heater temperature, but, unfortunately, this is the first thing that worries Tolyatti car owners. This is not about their shortsightedness, but about the imperfection of isolation, but this is not what we are talking about now. The engine temperature depends on a simple but very simple device called a thermostat. When we learn more about modifications of VAZ devices, the question of which thermostat is best to install on a VAZ-2114 injector will automatically disappear.

We will not organize self-improvement courses, since every self-respecting driver knows that the thermostat sends coolant either in a large circle (including the radiator to cool the engine), or in a small way (bypassing the radiator).

Thermostat for VAZ-2114 injector

The operation of the device depends on a thermodynamic valve, which closes one pipe in the thermostat and opens another. Before replacing the thermostat, it must be checked.

To upgrade his device to memory, we brought the VAZ-2114 thermostat circuit and screwed it on from below.

As you can see from the diagram, this is a conventional device with a thermal valve that, when a certain temperature is reached, releases antifreeze in a small or large circle.

Why replace the thermostat

The cooling system of a car of almost any brand includes the same components, namely:

• expansion tank;
• tank plug (responsible for releasing pressure);
• radiator;
• electric fan;
• thermostat.

At the same time, the connection diagram of these elements into one single circuit may be different, which causes peculiarities in the operation of the cooling system of a particular car.

Thus, on front-wheel drive VAZ cars, this system has not undergone major changes since 2108, and only during the development of Grant did the designers decide to make significant changes.

If you look at the diagram, it immediately becomes obvious that the basic cooling system 2114 does not include coolant passing through the heater radiator in a small circle.

This, together with the not entirely correct operation of the thermostat, leads to the fact that a lot of time passes from the moment the engine is started until the comfortable temperature inside the cabin reaches a comfortable temperature. The thermostat from grants 2114 will help correct this situation.

An installed Granta thermostat will help build the operation of the cooling system similar to that of the Lada Granta. In this case, the heater radiator will be connected in series, and not in parallel, and will begin to receive the heat given off by the coolant immediately from the moment the engine starts.

In addition, the modernized cooling system, thanks to greater heat dissipation, will help avoid possible overheating and boiling of the liquid in the expansion tank.

Checking the Thermostat

In order to check the functionality of a Lada Granta part on VAZ 2114, 2109, etc., you need to pour coolant into the system and wait until it warms up to operating temperature - 90 - 95 degrees.

Make sure there are no coolant leaks

First of all, pay attention to the thermostat. At the junction of the pipes, there should be no noticeable drips or the appearance of wet spots. If after 5 minutes of engine operation these symptoms are not detected, then the installation was completed correctly.

Next, if the stove of a VAZ 2114, 2109, etc. is turned off, you need to turn it on and wait until the liquid heats up. After this, you should feel a flow of warm air in the cabin, as the Granta thermostat helps the stove work better. If heat does not flow, then the part is defective and the valve inside it does not work.

What is needed for replacement

Before installing a grant thermostat on a VAZ 2114, you should purchase all the necessary parts and materials.

These include:

• the actual thermostat for Grant (to avoid mistakes, you can write down its catalog number - 21900-1306010-00);
• new thermostat gasket;
• a pair of M8 studs 85 mm long;
• lower radiator hose for Grant;
• tee for coolant return flow;
• clamps of the appropriate size;
• sealant (necessarily heat-resistant).

In addition to all of the above, it is recommended to purchase new coolant and replace it in the entire system after making the upgrade. This operation is not mandatory, but highly desirable.

Check and replacement

If the thermostat fails, it should be replaced immediately. It is impossible to say that the device has failed only on the basis of an initial check.

If the engine overheats during operation or does not warm up to operating temperatures quickly enough, the condition of the unit is checked. Based on the results obtained, replacement or repair is carried out.

The most effective way to check the thermostat is to remove it. The procedure is performed as follows:

1. Unscrew the crankcase protection mounting bolts, after which the protection must be removed and placed aside for a while.
2. Remove the cap from the expansion tank where the coolant is located.
3. Place a clean container under the drain hole (if you plan to pour the same coolant back into the system), unscrew the drain plug from the cylinder block and remove all coolant from the cylinder block.
4. Place a container under the drain hole of the cooling radiator, unscrew the plug and drain the antifreeze or antifreeze.
5. Loosen the clamps holding the hoses.
6. Disconnect the three hoses that are connected to your thermostat housing.
7. Loosen the tension on the clamps and remove the thermostat along with the hose. The short hose is disconnected from the thermostat.
8. Place the dismantled device in a container of water, which must be preheated to 78-80 degrees Celsius.
9. Start heating the water, stirring the liquid occasionally. The water needs to be heated to approximately 87 degrees Celsius.
10. If the thermostat is working properly, when the temperature reaches 87 degrees with an error of plus or minus 2 degrees, the main valve should open. If this does not happen, the device is faulty and requires replacement.

To replace the thermostat, it is enough to remove the old one in accordance with the specified dismantling instructions, and reassemble the unit with an already working device in the reverse order.

What to choose?

Many owners of a VAZ 2109 with a carburetor complain that the factory thermostat is insufficiently efficient. Because of this, especially in winter, you have to suffer from slow heating, when it is difficult to achieve even 60 degrees.

To solve this problem, it is recommended to install a thermostat from an injection VAZ 2110 with 8 valves for the winter and for the entire period of operation of the nine. This is an improved element that has obvious advantages compared to the original thermostat for the carburetor VAZ 2109.

1. You should install an injection thermostat starting from tens, taking into account the fact that we are not talking about the first versions of the VAZ 2110, but later, modernized ones.
2. On 8-valve engines, dozens of thermostats have become dismountable, unlike the 16-valve VAZ 2110 and those devices that were initially installed from the factory on the VAZ 2109. This allows, in the event of a unit breakdown, to disassemble it and partially repair it without completely replacing the device.
3. To repair a new thermostat, borrowed from a VAZ 2110 with an injector and 8 valves, it is often enough to disassemble the device and replace the thermoelement there.
4. The new unit turned out to be 50 millimeters shorter, which allows for more free space.
5. The new element has lost many of the clamps that are relevant for thermostats from the VAZ 2109.
6. The component has undergone quite a serious modification, which allows it to effectively maintain a stable temperature inside the engine cooling system.

I hope my article and the video I filmed will be useful for those who are freezing in the “chisels”.

Having suffered pretty much from the “dubak” in the car, frozen windows and snot under my nose, I wanted warmth in the car, especially before the coming winter. Either the car will finish me off, or I will finish it off. A couple of months ago, I thoroughly “Googled” this topic, re-read hundreds of pages of forums where guys are discussing whether life in the “nine” is in winter, or whether a painful death awaits there, and in the literal sense, with frozen windows and it won’t take long to break. Various options were offered, including a pump from a gazelle to pump as much coolant as possible through the heater radiator, and a “Polish thermostat” - made in Poland, and a remake of the original one, as well as a “six-hole” thermostat from the 10.

In the standard circuit, the output from the stove is connected to the “saxophone” - the supply pipe of the pump. In theory, there should be amazing coolant blowing through the stove, but no, a stone flower does not come out. When you turn on the heater blower, the temperature of the engine drops, which may be good, to drive all the heat into the cabin when you get sour in a traffic jam, so as not to boil, but don’t drive on water, fill in normal antifreeze or antifreeze and you will be happy. In order to understand the operation of the thermostat, read the forum thread, it’s all well explained there, I’m unlikely to write better. Now, what I needed to implement the great plan for heating myself in the cabin: 1. Thermostat 21082-1306010-12 85C 2. Hoses for the stove 16 (18) mm. 3. 18 mm tee (Volgov or Gazelle, xs). 4. Clamps 25-40 4 pcs. For large pipes. (It’s better to take “NORMA”, I took others, threw a couple away...) 5. Clamps 16-27 8 pcs. They will go to the stove hoses. It's better to take a couple more in reserve. 6. Clamps 10-16 4 pcs. For small hoses and plug. 7. 2 studs for 8 mm. 50 mm long. 8. Gasket for thermostat, paper. I couldn't find it, so I put it on sealant. 9. The pipe from 10 to the tank can, in principle, be replaced with an 18 mm hose. 10. Sealant. 11. Antifreeze / Antifreeze a couple of liters if it spills.
