As you know, the Lada Kalina generator belt (belt of attached units) gradually wears out, stretches, etc. during the operation of the car. For this reason, you should constantly check the tension of the generator belt, and also assess the condition of this element for delamination, cracks and other defects.
The fact is that if the alternator belt is worn out or loose, the alternator itself may work worse, which leads to problems with charging the battery. You can also note the appearance of extraneous noise (for example, the alternator belt whistles or makes noise). In such a situation, a worn belt needs to be changed or, at a minimum, tightened if possible. At the same time, the condition of the generator belt rollers should be checked.
It often happens that the belt itself is in good condition, without obvious defects. However, it cannot be tensioned due to the fact that the Kalina belt tensioner has failed. Next, we will look at how to replace the alternator belt on Kalina with your own hands, as well as how to change the Kalina tension roller.

Adjustment methods
Currently, there are three main methods of tensioning the alternator belt in cars:
- Using a special arc-shaped strip. In this case, the generator has two mounting points. One of them is an axis around which it can move within small limits. The other is the nut on the adjustment bar. If you release it, you can move the pulley to the required distance. This method is now considered obsolete. It is mainly used on VAZ classics.
- The generator is moved by rotating the adjusting bolt. This system has become widespread in cars of the tenth family.
- Using a tensioner. This is a special movable roller that rests on the belt between the generator and crankshaft pulleys. It is equipped with a screw mechanism. By rotating it, you can adjust the pressing force. This is exactly the kind of alternator belt tensioner on the Lada Kalina.

In order to improve visual control, remove the plastic engine casing. To check the condition of the belt, engage fifth gear in a manual transmission, push the car (or rotate the suspended wheel) and inspect the belt along its entire length. On a car with an automatic transmission, remove the right mudguard of the engine compartment and, by rotating the crankshaft by the bolt of the auxiliary drive pulley, check the condition of the belt.
With any of the gearboxes, the following method is also possible: apply chalk marks to sections of the belt and, turning on the starter for short periods of time, turn the crankshaft at small angles. We inspect the belt along its entire length, checking the areas covered by the marks.
The belt should not have cracks, tears or separation of rubber from the fabric base. A defective belt must be replaced. To do this, from the engine compartment side...
Belt selection and price
If the generator design has a tensioner, then the belt length is 883 mm. In the vast majority of cases, Kalina has 8 valves. If the generator is like on Grant, the length is 823mm.
When choosing a manufacturer, you should take into account that the official supplier of these belts for AvtoVAZ is GATES, so preference should be given to its products. Belts are also produced by BTR (lots of bad reviews), Continental, Finwhale, and ANDYCAR. It is better to buy Dayco 825 (manufacturer GATES), elastic belts are marked Poly-V, if not, then the belt is rigid. The price of belts is approximately from 500 to 1000 rubles.
Prices for alternator belts vary on average from 300 to 400 rubles, depending on the manufacturer, which is not affordable.

So far, we have shown operations that will allow, if necessary, to change the tension of the accessory drive belt. But to replace the belt, we have to dismantle the right support of the power unit, since it passes through the belt.
From the bottom of the car, remove the middle and right mudguards of the engine compartment. You can see how to do this in the article “Replacing Lada Granta coolant”. Next, we should remove the fender liner of the right front wheel or, having freed all the fastenings of the fender liner in the front and middle parts, bend the fender liner by the brake disc of the wheel.
We hang and remove the right front wheel and release the fender liner fastenings according to the diagram.
When to change?
VAZ Lada Kalina vehicles use a belt drive for auxiliary units. On cars with air conditioning, the service life of such a belt is no more than 30 thousand km. On simple versions of cars, the strap can last longer, but most owners try to change it after the same 30 thousand kilometers traveled. For various reasons, the belt may fail earlier, so it must be checked periodically during vehicle operation. There should be no cracks on the working track, and delamination on the outer part of the belt is unacceptable. If such defects are present, we immediately change the strap. Another signal to replace this element is a whistle or other noise when the unit is operating.
The process of replacing the belt on a Kalina with air conditioning (sixteen valves) is presented in a video from the user Alexander.

How to change it yourself?
The complexity of replacing the alternator belt on Kalina does not depend on the number of valves or additional units on the engine.
Replacement on 8 valve engines without tensioner
Replacing the belt on such an engine is the simplest; the only tools you need are a 13 mm wrench and a short flat-blade screwdriver. Since the tension in such a drive scheme is quite strong, when changing it is necessary to use only a Gates 6PK823SF or Dayco 825 six-V belt with the additional marking POLY-V. The remaining straps are too rigid, quickly collapse and damage the bearing on the generator shaft.

Advantages of a tensioner
Why weren't designers happy with the previous adjustment methods? Why did they add an extra video? It's not just about convenience. The tensioner significantly increases the service life of the generator. Without a roller, the entire load falls on its bearings. If the belt is tensioned normally, then there is nothing to worry about. In this case, the generator will last many thousands of kilometers. However, very often car owners overtighten the belt, and this is bad.
The load on the bearings increases many times over, so they quickly fail. In itself, this is not so scary and expensive, although repairing a generator is quite labor-intensive. But the car owner does not always recognize the breakdown in time. The bearings gradually “break”, the rotor moves and begins to cling to the stator winding. The result is the need to purchase a new generator. Of course, the Kalina generator belt tensioner pulley can also fail, which happens quite regularly, but that’s only 400 rubles, not twelve thousand.

The belt deflection in the area between the pulleys of the engine and the air conditioning compressor with an applied force of 100 N (10 kgf) should be within 6–7 mm.

Attention! Do not overtighten the belt. Excessive belt tension causes premature wear of the alternator belt and bearings.
Next, assembly is carried out in reverse order.

Lada Granta and Kalina: checking and replacing the auxiliary drive belt
What is it needed for?
As mentioned above, any vehicle is equipped with such an important device as a generator. If it fails, the operation of the vehicle will be impossible. Therefore, special attention should be paid to the performance of all elements of the device, be it a Lada Kalina with a 16- or 8-cl. engine, with or without air conditioning. What is the component size? How is the roller strap adjusted and replaced? How to tighten up? You can find out the answers to these questions in the article.
Car Lada Kalina tuning
Before answering questions that interest Lad Kalin owners, you should understand why this component is needed. Not every motorist knows what role he plays in the functioning of the car.
In modern cars, this belt is the only element that allows you to transmit crankshaft rotation to the generator. When the crankshaft transmits rotation to the device pulley, energy appears in the vehicle's electrical network, thanks to which all electrical equipment operates.

Let's sum it up
This completes the dismantling procedure. Now you know how to tension the alternator belt. The steps for reinstallation are also very simple, so there is no particular need to comment on them. Upon completion of the entire list of installation procedures, we check the tension level for compliance with the specified requirements. We start the engine and observe the operation of the unit. If no side factors are detected, then the work was done correctly.
Also in LADA Kalina it is possible to remake the tensioning device, which is confirmed by this video:
Repair technology for the auxiliary drive system
Sequencing
is similar for both models with and without air conditioning and consists of the following items:
- Remove the engine protection.
- Remove the right wheel and fender liner.
- Remove the expansion tank.
- Jack up the right side of the engine and unscrew the mount.
- By tightening the tensioner mechanism pin, loosen the belt tension.
- Remove the drive from the roller and then from all pulleys.
- Install the new part and reassemble in reverse order.
- Adjust the tension.
It is advisable to carry out work in an inspection pit in compliance with all safety measures. When changing the flexible connection, it is recommended to simultaneously install a new tensioner roller, but this depends on the desire of the owner and the condition of the unit.
Design
The main element of the tensioner is the pressure roller. It is made of plastic, and a sealed bearing is pressed inside. The roller is mounted on its own bracket, which, with the help of a threaded rod, can move in a vertical plane. This ensures the required moment of pressure on the belt. To prevent the bracket from moving spontaneously when the car is moving due to engine vibration, the pin is tightened on top with a locknut. The entire structure is placed on the generator bracket. There are two holes in it for attaching the Kalina generator belt tensioner.
