The thermostat protects the engine from overheating. You all understand what sad consequences overheating of the power unit can lead to, and what financial losses the car owner will suffer.

Where is he located

Determining where the thermostat is located on a VAZ 2110 is not difficult. It is located slightly below the air filter housing. Open the hood, find the filter housing and look a little lower, under it. This is where the lid is located, which, in turn, hides the desired part behind it.

Which one is better to choose as a replacement?

Experts do not advise experimenting with analogues, but using those components that AvtoVAZ develops directly for the VAZ 2110 model.

Although the company recommends using another technique - setting the thermostat from the VAZ 2111 to “ten”. Here is the answer to the question which thermostat for the VAZ 2110 is better.

The advantages of using an element from the eleventh model are manifested in the following:

• It is smaller in size;
• One hose and two clamps are used, which reduces the likelihood of leaks;
• The design of the product is compact and monoblock;
• The reduced cross-section of the small circuit guarantees better circulation through the stove;
• Relatively easy replacement.

Functionality check

Before changing the thermostat on your VAZ 2110, it is recommended to first check it for functionality. Sometimes the problem lies elsewhere, and craftsmen immediately take on the rather complex task of replacing the cooling element. There's no need to rush. First we will talk about how to check the thermostat on a VAZ 2110.

1. Radiator pipe heating. Grab the lower pipe with your hand and ask a friend to start the engine. First, the car must cool down properly, that is, be cold. At first, the pipe will also be cold, but when the engine starts, it will quickly heat up. If this happens, then the thermostat is working.
2. Thermocouple. To dispel doubt, perform disassembly. The thermoelement, which is responsible for starting the coolant circulation, is removed from the removed thermostat. Dip this element into water heated to approximately 75 degrees and heat it further. Now lower the thermometer into the water and monitor the temperature and the device. When the temperature starts to reach 90 degrees, the rod from the thermocouple should extend. If this does not happen, replace the thermocouple. This is a common problem and does not require a complete replacement of the entire thermostat. You should know how much a thermostat costs for a VAZ 2110 car, and you don’t really want to waste that kind of money.
3. New element. If replacement is still required, remove the old thermostat, take it with you to the auto parts store and buy the same new one. But be careful not to purchase a defective part. Blow into the fitting properly. If air does not come out from anywhere, then the part is working properly.

Signs of thermostat malfunctions and diagnostics

During operation, the thermostat valve is subject to operational and temperature loads, that is, it can fail for many reasons. Among the main ones:

• low-quality or used coolant (antifreeze);
• mechanical or corrosive wear of the valve drive, etc.

A thermostat malfunction can be determined by the following symptoms:

• The internal combustion engine of the car, without being subjected to special loads, overheats - the thermostat thermocouple has ceased to perform its functions. If everything is normal with the cooling fan, to check, dismantle the thermostat and check the functionality of the valve;

To check the thermostat on a VAZ 2110, you can use several methods, since there are several methods for diagnosing the thermostat for failure:

• Start the car and warm up the engine to the desired temperature, first opening the hood. Find the lower pipe coming from the thermostat and feel it for heat. If the thermostat is in good condition, the pipe will heat up quickly;
• Dismantle the thermostat and remove from it the thermoelement responsible for starting the coolant circulation. Place the thermocouple in water heated to a temperature of 75 degrees and keep it until the water warms up further (up to 90 degrees). In good condition, when the water is heated to 90 degrees, the rod from the thermoelement should extend.

If problems are found with the operation of the thermostat, it needs to be replaced. By the way, when buying a new thermostat, you need to check it by blowing into the fitting (no air should escape). Also, some owners, before installation, immerse the new device in hot water for insurance, as described above. This eliminates the risk of installing a faulty device.

Dismantling and replacement

Replacing the thermostat on a VAZ 2110 car will not be difficult, even without the help of specialists. You have checked its functionality and confirmed that it is faulty.

Removal

Removing the thermostat involves performing work in the following sequence:

1. Take a screwdriver, an 8 key, a 6 hex key and other tools.
2. Make sure the engine is cold. It is strictly prohibited to carry out work on a hot engine.
3. Drain the coolant by unscrewing the plug.
4. Remove the air filter.
5. Locate the clamp on the radiator hose. Loosen it a little, you don't need to remove it completely.
6. Disconnect the hose from the thermostat.
7. Using the same method, disconnect the coolant pump hose.
8. Using a 5mm wrench, unscrew the bolts that secure the thermostat. There are three of them on the VAZ 2110.
9. Remove the thermostat cover.
10. Remove the thermostat and rubber O-rings from the cover.

Installing a new component

Now let's figure out how to change the old thermostat from a VAZ 2110 to a new one.

As we have already noted, many craftsmen recommend using a thermostat from a VAZ 2111. It is more practical, more reliable, and more compact. Therefore, we offer recommendations for replacement with an eye to using just such a thermostat.

The installation process is not complicated, but it will require some care from you in performing each of the stages:

1. First, cut a special tee into the supply hose from the stove. This is necessary because some thermostats have five fittings without access to the expansion tank. And we need six.
2. Dismantle the distributor, which will make it easier to complete the following steps. But this is only relevant for a carburetor engine. In VAZ 2110 injection models, skip this step.
3. Be sure to mark the position of the distributor relative to the body of the additional units to avoid mistakes during reassembly. Otherwise, you will disrupt the ignition and the engine will not start.
4. Remove the tee from the cylinder head.
5. Clean the mating plane head from traces of the old gasket.
6. Get a new thermostat that fits your vehicle. Muffle the thin heating output using the throttle valve. You won't need it in the future.
7. Unscrew the top pin and install a new, longer one in its place.
8. Don't be alarmed, the new thermostat is shorter than the old one, the outlet and the pipe do not match. It's not scary. It is necessary to completely dismantle the pipe and put a new one in its place. An element from a VAZ 2112 is perfect. It is also advisable to find a new corner pipe.
9. Install a new pipe, do not forget about the gasket.
10. Shorten the elbow and screw it into place.
11. Replace the standard heater hose with a new one that fits your thermostat.
12. Connect the expansion tank, which is specially designed for this purpose, to the fitting.
13. Check the quality of each connection so that you don’t have to do all the work again later.
14. Fill with new coolant.
15. Remove all air from the system.
16. Warm up the engine until the fan comes on. To do this, it is necessary to warm up the power unit to approximately 85 degrees.
17. If you don’t notice any traces of drops or leaks, it means you replaced the part correctly.

First you need to drain the used antifreeze. Insert a 7-liter container under the barrel drain hole and the liquid will drain completely into the tank. After this, the cooling system should be cleaned; it is best to use a special cooling system detergent . Acids, soda and vinegar do not give such good results, and lactic acid can destroy the interior of the car.

After filling with detergent, add water inside and turn on the VAZ-2110 for 20 minutes. This promotes rapid detachment of dirt and scale from the walls of the pipeline. The expansion tank must also be thoroughly flushed. Now unscrew the clamps coming out of the radiator, then do the same with the clamps on the inlet hose of the pump tube and the hose that serves as the connecting element between the exhaust pipe and the thermostat.

Remove the thermostat, insert a new sample and try again. Don't forget to add coolant.
