Tensioning the VAZ 2110 alternator belt is a mandatory procedure not only after replacing the “gene” belt, but also periodically during operation (the degree of belt tension is checked every 10 thousand km). Tensioning or loosening the VAZ 2110-2112 generator drive belt is quite simple (there is a special bolt for this). To establish sufficient tension in the generator belt, you must first loosen the two fastening bolts, and then adjust the degree of tension by adjusting the tensioner. The manual says very abstrusely - “when exposed to a force of 100 Newtons (10 kgf), the belt should bend between the pulleys by 1.5 cm, but in practice, the belt tension first occurs by eye, and then is adjusted depending on how well the gene copes with load when electrical appliances are turned on. After completing the procedure, do not forget to tighten the generator mounting bolts.

There are times when when the car gets into a puddle, or simply when there is high humidity, the alternator belt begins to whistle. Often the reason lies precisely in insufficient tension. Of course, to fix this problem, you just need to tighten the belt to the desired level.

The tool you will need to solve this problem:

Head for 10 and 13 mm
Ratchet handle

So, depending on the VAZ 2110-2112 model and the installed engines, the design of the alternator belt tensioner may differ slightly. But in essence, there is not much difference and everything is done by analogy.

So, open the hood of the car and look towards where the generator is located.
Loosen the top nut securing the generator and use the adjusting bolt to tighten it

Why does the whistle occur?

There are several reasons why the characteristic whistle-like sound occurs.

Weak tension. The element slips, and this happens most actively at night. The increased intensity of the whistle at night is explained by the fact that the generator additionally works for lighting.
Gradually the component is destroyed. The belt can dry out, causing its structure to be disrupted and it literally crumbles into pieces. The first signs are cracks, and then whole pieces break off. When moving, the pulley hits and slipping begins. Only replacement is required here.
Although moisture gets on the belt very rarely and evaporates almost immediately, the connection can still whistle. In this situation, tension is required.
The generator itself jams.

Important points

Thus, on VAZ 2110 cars the timing belt needs to be changed every 45 thousand kilometers. This figure is not final, it is approximate and depends on the operating conditions of the vehicle. For this reason, you need to check the belt for integrity every 10 thousand kilometers.

Note! It is worth noting that a worn belt, which was replaced for the reason that “the time has come” is still operational, does not need to be thrown away immediately, let it be used as a spare element.

VAZ 2110 how to tighten the alternator belt

The correct functioning of the entire assembly is largely influenced by the tension of the timing belt. For example, if after changing the belt the generator starts to howl, then most likely the belt is simply too tight. If the element slips, this may indicate that it is not tightened correctly. Of course, to replace a belt, in principle, just like to change a clutch cable, you need some spare parts with tools. When purchasing a spare element, you need to know the dimensional parameters of the belt, and it is advisable to give preference only to well-known manufacturers.

Performing tension

If there is no wear on the V-belt drive, but there is a whistle, first of all, check the tension level. We will not use complex terminology, but will simply advise you to press with some force on the belt in the middle.

If the tension is done correctly, then the belt will bend no more than 8 millimeters. If the deflection is greater, then the element will have to be tensioned, and if it practically does not deflect, the tension will have to be loosened. The problem is not the whistling. Due to weak tension, the battery does not charge effectively, and the drive itself begins to wear out faster. Excessive tension can lead to damage to the alternator bearings and stretching of the belt.

Correct tension of the VAZ 2110 generator belt is performed as follows:

Loosen the generator from the bottom and top. A nut is used for this;
Turn the adjusting bolt and adjust the belt;
If you want to increase the tension, the bolt is turned to the right. Thus, you move the generator away from the cylinder block;
To loosen the tension, move in the opposite direction - to the left;
Use a wrench to grab the fastening bolt and turn the crankshaft a couple of turns, then check the tension;
If all is well, the tension is correct, the nut can be tightened back.

Dimensions

It is quite possible that you have selected the wrong alternator belt size for your 16 valve VAZ 2110. This often causes whistling. The correct size of the alternator belt for the 8 valve VAZ 2110 should be determined in advance, even before going to the auto parts store.

The sizes are different, and they are individual for each VAZ model.

If we talk specifically about the “ten”, then adhere to the following rules for choosing a belt size:

In the absence of air conditioning and power steering, 742 millimeters is suitable;
If the car is equipped with a hydraulic booster, then the size will be 1115 millimeters;
If an air conditioner is also present, then the optimal size is 1125 millimeters.

Some craftsmen regularly use original belts from other AvtoVAZ models - Priora and Kalina - to replace them when repairing their "ten".

Replacement

We have already figured out how to tighten the alternator belt. But such measures are not always relevant. If the element is cracked, overstretched and no longer tensioned, then there is nothing left to do but replace it with a new one.

In fact, replacement cannot be called a complex procedure. Follow the instructions and everything will work out.

Slightly loosen the bolt nut from the lower mounting of the car generator, as well as the tension nut.
Loosen the tension of your belt further. You already know how to do this from the previous section, where we talked about tensioning the alternator belt.
Move the generator towards the power unit, which will allow you to remove the belt from the crankshaft and generator pulleys.
The next step is to install a new element. To do this, you will need a high-quality belt purchased from a trusted store. What exactly this part will be and what size it will be is not difficult to determine. But quality comes first.
First, the belt is put on the crankshaft pulley.
Now it goes to the generator pulley.
At the last stage, you have to repeat the tension adjustment procedure. You already know very well how this procedure is carried out, so there should be no problems.

So, open the hood of the car and look towards where the generator is located.
Loosen the top nut securing the generator and use the adjusting bolt to tighten it

Pay attention to the fact that if it is necessary to tighten the belt, the bolt must be tightened on the rod clockwise. If, on the contrary, you decide to loosen the tension, then unscrew the adjusting bolt counterclockwise.

Motorists Council

As practice shows, many experienced VAZ 2110 drivers, who have been driving this particular model for many years now, carry an additional alternator belt with them in the trunk. This is due to the fact that its breakdown can occur at the most inopportune moment. This node cannot be called the weakest point of the “ten”, but problems may arise with it. And it is better for you to be prepared for such a situation.

Otherwise, you will have to call a tow truck, go to the nearest service station, and pay a lot of money for the services of specialists. Although, if you have a spare alternator belt and a standard set of tools, if it breaks, you would spend literally a couple of tens of minutes and calmly continue driving with a new belt. Because the choice is always yours!

Replacing the VAZ 2110 alternator belt: procedure

Alternator belt VAZ 2110

On a VAZ 2110, replacing the alternator belt is an extremely important point that guarantees the long life of your car’s battery. An unexpectedly failed or loose belt causes the battery to be undercharged during operation, quickly depleting its capacity and, accordingly, causing battery failure in VAZ vehicles.

Strong constriction causes breakdown of the generator itself, associated with premature wear of the bearings and belt drive. But do not rush to despair - there is nothing easier than changing the alternator strap yourself, just like checking the degree of its tension, the main thing is to know how. Replacing it yourself will take you no more than 20 minutes of your personal time.

Thus, you do not have to visit a service station every time, and knowing the service life of the product, it will not be difficult for you to monitor its condition and regularly change it according to the manufacturer’s recommendations every 45 thousand kilometers, together with us learning the basics of automotive literacy of the VAZ 2110.

Checking the alternator belt

What's better? Comparative characteristics of offers from popular manufacturers.

Many VAZ alternator belts, which have existed for a large number of years on the market, both domestic and imported, were specifically subjected to intense, many-hour loads on a bench in a testing laboratory, so you do not have to check their reliability from your own experience, you can only draw the appropriate conclusion from the comparative recommendation offered below.

If you decide to buy yourself a new alternator belt for a VAZ 2110, we recommend that you pay attention to the offers of the following manufacturers:

1) Bosch, Italy, you can remain calm about its technical condition during the declared service life. 2) FLENNOR - import offer for VAZ of German quality. 3) QH imported to Russia from Belgium; 4) GATES, produced and supplied to us from England; 5) CONTITECH - another “German”, somewhat inferior in quality to its older brother.

Basic criteria for the right choice

What are the main characteristics that not only the VAZ 2110 alternator belt, but also any other car must meet? Firstly, this is, of course, a low degree of stretching during operation. If we talk about quality standards, this parameter should not go beyond 2.5% of the standard length under the influence of a suspended load of 50 kg.
