What is this device for? It ensures that the engine can heat up in the shortest possible time or, on the contrary, practically not heat up. The thermostat is equipped with a valve, inside of which there is a special substance. This, in turn, influences the fact that the thermostat on the VAZ 2110 with 16 valves decides when to open and when vice versa.
It is known that while the engine is running, the car can quickly heat up to 80 degrees. After this mark, the heating rate decreases, and after 94 degrees the car stops heating, provided that the car is not in a multi-kilometer traffic jam.
Where is the VAZ 2110 thermostat located?
It can be found just below the air filter housing. To see the VAZ 2110 thermostat, you need to look into the engine compartment and find the air filter housing. After this, it’s worth looking under this housing, so to speak, and you will be able to see the desired thermostat, or rather its cover. The device itself is hidden under it.
When to think about replacement
If the device has stopped opening the valve that releases coolant to a large circle, or the valve is simply jammed and does not close on its own, then you need to think about replacing the Grant thermostat on the VAZ 2110. If you do not replace the device in time, negative consequences may occur.
If the fluid cannot circulate in a large circle, the car will overheat. This should not be allowed and, if possible, the thermostat from the Granta VAZ 2110 injector 16 valves should be replaced as soon as possible. Overheating can cause the cylinder head gasket to burn out. Moreover, the friction of the car itself will increase.
If the valve gets stuck in the open position, which is extremely rare, the motor will not be able to heat up. It is also advisable to replace the device.
Three cases for replacing the thermostat
Since the thermostat is a fairly simple part, it only needs to be changed in three cases:
- If the valve is stuck closed and the antifreeze flows only in a small circle .
- If the valve is stuck open and the coolant circulates only in a large circle . This point also includes cases when the valve jams in a half-open position.
- If the machine is operated in a hot climate and the standard thermostat cannot cope with the load , it must also be replaced with another model that will be designed for use in hot climates.
If in these cases the procedure for replacing the thermostat is neglected, this can lead to overheating of the engine, or even to its seizure. It is difficult to kill the engine on a VAZ-2110, but such a “trifle” can do it!
Valve stuck closed
An old thermostat and even a new one can jam if the product is of poor quality.
We recommend: How often should you change the air filter in your car?
As for the case when the valve is stuck closed, this is very dangerous for the engine.
Of course, each of the drivers in the summer observed the picture of cars standing with an open hood, steam pouring out from under it, and a puddle spreading under the car. This situation occurs due to overheating of the coolant, which expands when heated and ruptures the pipes or radiator.
How to Determine a Bad Thermostat Even with a Bad Engine Temperature Sensor
Although many drivers regret a burst radiator, it is not the worst thing that can happen. It happens that an overheated engine simply jams, since the metal expands very strongly when heated. Therefore, the antifreeze temperature must be constantly monitored.
If the temperature sensor fails, an experienced driver can determine the increase in temperature by the behavior of the car. When the engine overheats, it begins to become very “dull” , that is, it slowly picks up speed and speed. In this case, it is recommended to quickly stop driving and wait until the engine cools down.
If the thermostat valve gets stuck open, you may not even notice it in the summer. In winter, this problem can be identified by the slow heating of the interior.
How to find out what condition the thermostat is in: working or not
To check the thermostat on a VAZ 2110 it is not necessary to remove it from the car.
You can simply start the car and warm it up to operating temperature. After warming up, leave the cabin, open the hood and look into the engine compartment. There you will need to find the lower pipe coming from the thermostat itself. This detail needs to be thoroughly felt. If it is slightly warm at the very beginning, and gradually warms up as the engine warms up, then the thermostat is working as expected. If the lower pipe remains cold, then the thermostat needs to be changed. To check the functionality of the VAZ 2110 8-valve injector thermostat, you can disassemble it and remove the thermocouple. He is precisely responsible for the operation of the cooler. It needs to be checked. To do this, you need to take hot water and lower this element into it. You will need to place a thermometer in the water and observe how the temperature changes. The device itself will also need to be monitored.
The water will need to be heated. Once it reaches 90 degrees, the thermocouple rod should extend. If this is not the case, then this part needs to be replaced. By the way, in most situations in the VAZ 2110 you do not need to completely change the thermostat. This is quite expensive and, as a rule, is only necessary when there is visible damage.
When the need arises to replace the thermostat from Granta for a VAZ 2110 injector 8 valves, car owners are forced to buy a new device. You should also be careful here. It is advisable to check the device before purchasing. To do this, blow strongly into the fitting. If it is not noticeable that air is passing anywhere, then a small circuit prevents its passage. This means that such a part is not worth buying. How much does a thermostat cost for a VAZ 2110? It is impossible to answer this question unambiguously, since the price depends on whether the unit is new or used.
How to choose a thermostat: recommendations
All thermostats installed on the VAZ 2110 before 2003 were of an old design (catalog number 2110-1306010). A little later, after 2003, changes were made to the cooling system of the VAZ 2110.
Accordingly, the thermostat was also replaced (catalog numbers 21082-1306010-14 and 21082-1306010-11). The new thermostats differed from the old ones by increasing the thermoelement response level.
We also recommend reading the article about why the engine does not warm up to operating temperature. From this article you will learn why the engine may not reach operating temperature, the engine takes a long time to warm up, etc.
The choice of non-original assembled thermostats for the VAZ 2110 today is quite large, but, according to many experts, it is necessary to use only those that are directly developed and manufactured by AvtoVAZ for the VAZ 2110.
Let us also add that on the VAZ 2110 you can install a thermostat from the VAZ 2111, since it is smaller in size, structurally compact, and the use of only one hose and two clamps reduces the likelihood of leakage.
Step-by-step process for replacing the thermostat in a VAZ 2110 injector 8 valves
The first thing you should know is that the part is replaced only when the engine is cold. If the thermostat is replaced while the engine is hot, you may get severe burns. Therefore, it is worth observing safety measures.
How to replace the thermostat on a VAZ 2110 with your own hands:
- Drain all coolant from the engine. This is important for successful thermostat replacement.
- Remove the air filter housing.
- Take previously prepared tools and loosen the clamps of two hoses: the coolant pump and the radiator. Disconnect the hoses.
- Now you need a hexagon. They will need to unscrew the 3 bolts securing the thermostat cover and carefully remove it. Under the cover you will find the device itself, which needs to be replaced.
- There is also an O-ring on the cover itself. It may be severely compressed or cracks or other damage may appear on it. In this case, the ring itself should be replaced.
How to install the thermostat:
It is necessary to carry out all the same actions that were carried out to remove the device, only their order should be reversed.
If a complete replacement of the VAZ 2110 thermostat is necessary, then you need to remove the one that has stopped working normally and replace it with a new unit. After this, the cooling system must be filled with antifreeze. It is filled through the expansion tank. You can use new liquid or already filtered one.
To eliminate possible air pockets, the car should be started and allowed to idle for some time. The car should warm up. This way you can eliminate all air pockets.
At the end, it’s worth checking to see if there are any leaks and if the coolant is at the normal level.
