and in a car? Even the most inexperienced car enthusiast can easily answer this question. But if there are still difficulties in determining the role of the generator belt, then in short, we can answer as follows. Generator belt
transmits torque from the crankshaft to. And if the belt tension drops, it functions properly.
Signs of poor alternator belt tension
Probably everyone heard the whistle coming from under the hood when the car started moving. This is the kind of whistle that the alternator belt makes if it has low tension or needs to be replaced.
Also pay attention to the instrument panel after starting. If the light bulbs change brightness after , then the alternator belt needs tension.
How to check belt tension in 2110, VAZ 2111, VAZ 2112
We open the hood of the car and on the left side we see, which is driven by the generator belt. If we take the manufacturer’s data, the correct tension of the generator belt will be if under a force of 100 N (10 kgf) the deflection is no more than 10–15 mm. As a rule, to check the tension of the generator belt, you just need to press the belt with your thumb; if the deflection is more than 10–15 mm, you need to adjust the tension or replace it.
Replacing the alternator belt, VAZ 2111, VAZ 2112 (without power steering)
As you know, the operation of a belt drive allows the car's generator to convert energy, creating an electrical charge. If any part fails, the generator can no longer function normally. This is especially true for the belt. On a VAZ 2112, replacing the alternator belt is an important procedure that is carried out every 10 thousand km. Replacing the VAZ 2112 alternator belt can be done on your own. As mentioned above, the part needs to be changed in a timely manner, otherwise problems cannot be avoided. The main sign of failure of the alternator belt is cracks, which the driver of the vehicle must notice.
Note. The car manufacturer's instructions recommend changing the belt every 45 thousand km, but in practice this is not the case. Poor road conditions, incorrect initial driving style and much more negatively affect this part. Therefore 10,000 km. mileage is a feature that in practice determines replacement time.
Selecting a belt manufacturer
Today, choosing a manufacturer of a particular spare part can be quite difficult due to the fairly wide selection. But if we look at the statistics of many car owners and service stations, we can conclude that the highest quality belts for driving auxiliary units are:
- BRT - Balakovo Rubber Equipment, often installed from the assembly line
- GATES - often also a factory option
- Bosch - has a fairly wide range of products, including belts, and the quality is quite high
- LUZAR
- ANDYCAR
If we consider the most trouble-free belts, then according to statistics from surveys of motorists and service station technicians, we can conclude that the highest quality ones are produced by GATES and domestic BRT.
If you use another manufacturer, or want to leave your review, you can share it in the comments below.
Replacement without power steering
As a rule, it is customary to separate instructions by . If the car does not have power steering, then the step-by-step replacement instructions will look like this.
First you need to check the tension to determine the degree of wear. A normal belt, naturally free of cracks, should bend by 10 or 15 mm if it is subjected to a force of 100 N or 10 kgf. The force must be applied exactly in the middle, right between the generator and the crankshaft pulley. If the tension is weak or, on the contrary, tight, you need to either adjust the part or replace it.
Replacement algorithm
So:
- Raise the front of the car;
- Remove the crankcase protection;
- Loosen the nuts securing the upper and lower mounts of the generator;
- We turn out the adjusting bolt (we do this to the maximum possible value);
- We dismantle the old belt.
Note. You need to remove the part by moving the generator as close to the cylinder block as possible.
- We put a new belt on the crankshaft;
- Then the tension should be adjusted.
Replacement with power steering and air conditioning
If changing the alternator belt on a car without power steering takes only ten minutes, then on the contrary, in the case of power steering or air conditioning, as on the Priora, the procedure becomes noticeably more complicated.
The fact is that if power steering is installed on the car, then the location of the generator is already in a different place. The power steering pump is installed in its original position. The generator itself is moved higher in this case. In addition to the fact that on cars with air conditioning and power steering, the location of the generator has been changed, the belt itself also runs on a different axis. In this case, the part first passes through the crankshaft pulley, then the tension roller, the generator shaft, the pump shaft and again the crankshaft pulley.
Note. The replacement procedure on a car with power steering is complicated by the fact that the belt rotates around the left engine mount. Thus, in order to replace the part, you should lift the engine, and only then remove the chain.
Let's begin the replacement procedure:
- First, loosen the generator belt;
- unscrew it.
Note. The bolt of this very support should, in theory, fall down after unscrewing, but it is possible that its head will rest against the power steering pulley. If this happens, it's okay. You will need to unscrew the power steering pulley, then unscrew 3 bolts, remove the pulley and pull out the bolt.
- We lift the engine using a bottle jack (it should be installed through the oil drain hole, and a wooden block should be placed under the edge so as not to crush the edge of the crankcase);
- Remove the crankcase protection;
- Now take out the support nut;
- We pull the generator belt through the support;
- We remove the part.
Installation of a new part is carried out in the same sequence. But before buying a new belt, you should know that the part must have 6 rivets. In addition, the length of the generator belt must be exactly 1115 mm. If such a chain is not commercially available, then it is recommended to install a Priora belt with air conditioning.
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:
- We dismantle the “minus terminal” from the battery.
Remove the negative terminal from the battery
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:
When everything is considered, it is worth considering the reasons that accompany the replacement:
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.
Tension
After installing a new belt or in general, during operation the part may need to be properly tensioned. As mentioned above, poor tension leads to various problems in the functioning of the car.
Simple tension without power steering
So:
- We move the generator away from as far as possible;
- We rotate the adjusting bolt clockwise - the belt is tensioned;
- If we want to loosen it, turn the adjusting bolt counterclockwise;
- We turn the crankshaft by the mounting bolt 2 turns;
- Check the tension again (if necessary, adjust again).
Tension with power steering
As in the case of replacement, the tension of the alternator belt on cars with power steering is different. The point again is that the angle of the belt wrapping around the pulley is quite small. If you simply tighten it, as in the first case, then it will slip. For this purpose, the tension is greater, as indicated in the instructions for cars with power steering. The above step-by-step instructions will help you do everything successfully with your own hands. It won’t hurt to look at photos or video materials during the work process, as examples of visual aids. The cost of replacing an alternator belt at a service station is quite high, so there is no need to pay extra money.
Hello, dear car enthusiasts! Quite quickly, VAZ cars of the tenth series spread across the territory of our country.
The new design, economical engine and affordable price began to expand the circle of fans of these cars.
The designers proposed quite a lot of new technical solutions that made it possible to improve the performance of the cars, however, some components and mechanisms were borrowed from previous models, where they had proven themselves positively.
So, for owners of VAZ 2112 cars, tensioning the alternator belt is not at all difficult if they already owned earlier models of the VAZ family.
Despite the widespread desire of developers to improve the design of cars, electricity is still the only possible option.
Why invent something new if two pulleys and a belt between them are a simple and very reliable mechanism. Both tensioning and tensioning are not difficult, the drive works in any conditions.
The only drawback of the technological process of replacing the VAZ 2112 alternator belt is a more cramped environment in the engine compartment due to the transverse location of the engine.
Tensioning the VAZ 21124 alternator belt
The most important indicator for assessing the correct operation of the belt drive is. The engine crankshaft rotates at a speed of several thousand revolutions per minute.
In this case, sharp decreases or increases in rotation speed often occur. In such conditions, the belt drive must fit very tightly to the working surface of the pulley, providing good traction.
If it is a VAZ 2112, then with a high degree of confidence we can say that the belt is not tensioned sufficiently. When the rotation speed changes, the pulley rotates and the belt slides along its surface, producing a characteristic sound. In addition to the unpleasant squeaking sound, you must be prepared for the fact that the belt quickly overheats and may fail.
A highly tensioned VAZ 21124 alternator belt can also lead to various breakdowns, the most common of which are:
- wear and failure of generator bearings;
- bracket bending.
To check the correct tension of the belt, press it in the middle between the pulleys. With a force of 10 kgf, the subsidence should be 10-15 mm.
The tension is adjusted using ordinary wrenches, for which you should loosen the nuts securing the generator to the bracket, adjust the tension using the adjusting bolt and tighten the fastening lugs again.
Replacing the VAZ 2112 alternator belt in the garage with your own hands
As much as we wouldn’t like it, most of the machine’s parts have their own service life, after which they need to be replaced.
A VAZ 2112 alternator belt, provided it is of high quality and careful operation, can provide a mileage of over 100 thousand km, but it is better to replace it without tempting fate after it has served the period specified by the manufacturer.
Replacing the 2112 alternator belt
is done in the following order:
- the car is installed on a viewing hole, since access from below to the belt is more convenient;
- after disconnecting the battery, the upper and lower nuts securing the generator are loosened;
- the adjusting bolt is unscrewed and the generator moves to the engine block;
- remove the old one and put on a new alternator belt.
The belt is tensioned as described above. Considering that a new belt is being installed, after a short period of use, it may stretch slightly and the tension will weaken. This can be eliminated by additionally tightening the generator drive belt to the parameters set by the manufacturer.
The operation of the belt drive allows the generator to convert the mechanical energy received from the engine into electrical energy. It is for this reason that the serviceability of all generator parts, especially the drive belt and belt tensioner pulley, is especially important.

How to tension
1. The generator drive belt should bend by 10–15 mm with a force of 100 N (10 kgf) applied in the middle between the crankshaft and generator pulleys. Otherwise, adjust its tension.
2. To do this, loosen the nuts of the lower and...
3. ...top mounting of the generator.
4. To tighten the belt, move the generator away from the cylinder block by turning the adjusting bolt clockwise. To loosen the belt, move the generator to the cylinder block by turning the adjusting bolt counterclockwise.
5. Using a wrench, turn the crankshaft by the pulley mounting bolt two turns clockwise and check the belt tension again. Repeat the adjustment if necessary.
6. Tighten both generator mounting nuts.
7. It is more convenient to check and adjust the tension, as well as replace the generator drive belt, from below the car. To do this, you need to lift the front of the car and remove the engine crankcase protection.
8. To replace the belt, loosen the nuts on the lower and upper fastenings of the generator, turn out the adjusting bolt as much as possible and remove the old belt, moving the generator as far as possible towards the cylinder block. Place the new belt on the crankshaft pulley and then on the alternator pulley. After this, adjust the belt tension.
How to change
Tools
You should prepare for the replacement procedure by preparing:
a set of keys; jack; new consumables.
The replacement procedure is different for cars equipped with and without power steering. Below we will consider both options.
Replacing the alternator belt on a VAZ 2112 16 valve with installed power steering consists of the following steps:
First, remove the power steering fluid reservoir.
Then, using a key set to “13”, you need to unscrew the nut, thanks to which the generator is attached to the mounting plate. Generator drive with hydraulic booster
To remove the old strap, loosen the tension roller.
To remove the dismantled part, you need to remove the motor from the support. First you need to unscrew the cushion, and then jack up the engine until a gap appears. We take out the belt through the gap formed.
Assembly is carried out in reverse order.
There are some nuances during installation. First, the tensioner must be clamped to its extreme position.
Then you should tighten the belt on all the pulleys and lastly on the tension roller. This procedure is a little labor intensive.
After complete installation, it is necessary to tension the belt. Using the hammer handle, press and fix the tensioner.
At this stage, the difference between cars with hydraulic booster appears - they do not have an adjusting bolt. Tension adjustment is done using a tension roller.
The procedure on a car without power steering is simpler:
Using a “13” wrench, unscrew the generator mounting nut.
We loosen the belt tension by turning the adjusting bolt with a wrench to “10” counterclockwise.
Having moved the generator towards the cylinder block, we remove the belt.
At the next stage, we tighten the strap using the adjusting nut. We move the generator as far as possible from the cylinder block. By rotating the adjusting bolt clockwise, we increase the tension, and counterclockwise, we loosen it.
Then the crankshaft must be turned two turns and the tension checked again.
