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.

1. So, open the hood of the car and look towards where the generator is located.
2. 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.

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:

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

Replacing the alternator belt on a VAZ-2110, 2111 and 2112 with power steering with your own hands

It should be noted that the alternator belt plays an important role in the proper functioning of the vehicle’s on-board network, because it is it that transmits torque from the crankshaft to the alternator. The operating efficiency of the generator itself, whether the battery is fully or not fully charged, as well as the service life of the bearings of the generator itself depend on the condition and correct adjustment of the tension of the generator belt. If adjusted incorrectly, the bearings on the VAZ-2110 - 2112 generator will fail very quickly. Due to weak belt tension, its wear increases sharply; insufficient tension is usually indicated by such symptoms as belt whistling when slipping. According to the regulations, replacing the alternator belt on a VAZ-2110 - 2112 must be done at least once every 50 thousand kilometers, or if damage in the form of cracks is visually visible on the belt and a high degree of wear is observed.

So, we will tell you how to replace the alternator belt on a VAZ 2110 on your own. To make it easier for us to get to it, we tilt the reservoir with power steering fluid and the adsorber to the side, otherwise it will be inconvenient for us to get to the tension roller. Using a key set to “13”, unscrew the lock nut. We also use it to loosen the nut that clamps the “gene” to the mounting bar. After this, we move the generator in the direction of loosening the belt tension. We release the tension roller, the generator belt weakens and sags.

Since in our case we are considering a ten with power steering, we need to remove the engine from the support, this is not difficult and not scary.

We simply unscrew the two bolts securing the support and then use a hydraulic jack to raise the engine a couple of centimeters. Now we calmly pull out the old belt and immediately thread the new one, release the engine from the jack, tighten the mount and the two previously unscrewed bolts. We tighten the tension roller to the extreme position, thereby maximizing the belt tension. Then we tighten the belt as much as possible by changing the position of the generator, now we proceed to adjust the belt tension. The tension of the generator drive belt on a VAZ-2110 is checked as follows - with force, it should bend by about 10–15 mm when the belt is pressed between the generator pulley and the crankshaft. With proper tension, there should be a gap between the “frame” and the platform with the thread for the adjusting screw of about 15-20 millimeters. The arrows in the picture indicate the screws for adjusting the tension of the alternator belt.

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.

Replacement with power steering

Changing the drive on a VAZ 2110 is much more difficult if your car has a power steering system. In this case, where a car without power steering has an electric generator, the power steering pump is located, and the generator is located slightly higher. In this case, the belt passes through the crankshaft pulley, the generator shaft, the tension pulley and the power steering pump shaft. Replacement in this case is complicated by the fact that the drive passes around the motor support. This means that to replace it you need to unscrew the support, raise the motor, and then change the drive.

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!

Alternator belt replacement process

Alternator belt location

Before starting the replacement process, it must be said that the belt drives the generator, which in turn maintains a stable on-board network and also charges the battery.

So, let's get straight to the process itself:

1. We dismantle the “minus terminal” from the battery.

Remove the negative terminal from the battery

Removing the power steering reservoir

After unscrewing the fixing bolt, let the generator run

Remove the lower engine mount to pull out the belt.

Pull the alternator belt through the slot

Belt tension

There is a special wrench for correct tension of the alternator belt.

Product selection

The choice of alternator belt should be taken quite seriously, since its breakage will not disrupt the operation of other parts, but further movement will not be possible.

Also, it is necessary to immediately determine the quality of the product, since the work and service life will depend on this.

Causes and factors of belt life

There are quite a few reasons why the belt wear process will depend. Let's consider the main ones:

• Terms of Use.
• Climate of car use.
• Driving style.
• Product quality.

When everything is considered, it is worth considering the reasons that accompany the replacement:

1. Appearance of cracks and tears . This is the first sign that the belt is very worn and may soon break.
2. "Washability" of the inner surface . This usually happens when the generator pulley and the crankshaft are not on the same contact line, or the belt is installed crookedly.

Of course, in addition to everything, it is worth considering that you may get a defective product that does not reach its normal service life.
