LOCATION

Finding the Alternator belt in a VAZ 2114 is not difficult; when you open the hood, it is immediately visible. There are 2 criteria by which you can easily see it - firstly, it differs from all other belts in that one of its sides is toothed, and secondly, it connects not only the crankshaft and camshaft, but also passes through several small auxiliary parts . If you still don’t understand where it is, let’s first find the generator itself, it is located to the left of the car engine, not far from the right headlight, on the right side of the passenger compartment - accordingly, the belt is located on the generator itself (logically).

Also, before talking about changing, it is necessary to mention that in any case, no matter how carefully the car is operated, and no matter how often you drive it, the alternator belt will begin to deteriorate. Perhaps it will slide, or maybe it will be eaten away, it doesn’t matter, the main thing is that in any case it will become unusable. Therefore, its condition must be monitored very carefully, because no one wants it to break on a long journey.

When to change the drive belt on a car?

One of the main problems when belts used in various types of drives wear out is the presence of extraneous sounds that arise during operation.

The task of the installed pulleys is to transmit rotational motion to the attachments of the power plant.

If you get into such a situation, one or more belts may break. When should you change the drive belt to avoid getting into a difficult situation?

Belt drive. The drive belt on a machine is a part of the belt drive necessary to be able to transmit rotation from the motor.

The process is ensured by the action of friction or meshing force, for which V-shaped or timing belts are used. The opinion that the timing belt does not belong to the drive belt is also incorrect.

Drive belts are divided into several groups:

Timing belts, which is a belt transmission of the gas distribution mechanism;
Belt drives of auxiliary systems, that is, engine attachments.

There are three types of belts used on cars:

Timing belt having a toothed shape;
Poly V-belt, the purpose of which is to transmit rotational motion from the power plant to attachments;
V-belt with a similar purpose.

In Russia, these types of belts also have second names - flat (for poly-V-ribbed) and rivulet (for V-belt).

The difference from the timing belt is that it requires more careful attention and timely replacement as planned. Despite this, they also have their own time frame within which they must be replaced without waiting for them to fail.

The occurrence of a squeak or whistle becomes a sign that the belt may have become loose and is slipping along the pulleys.

CHANGING THE GENERATOR BELT

Surely, if you are looking for tips on how to remove the alternator belt and then put it back in place, you have already encountered the problem of its malfunction. Know that in order to perform the replacement correctly, you do not need to contact a car service; you can easily perform this procedure yourself . So, first we need to decide what tools we need to replace the alternator belt:

Socket wrenches for 17 and 19, you can also use open-end wrenches;
10mm socket;
Special tension wrench;
Flat screwdriver;
Ratchet wrench.

Attention! Before starting work, be sure to remove the negative terminal from the battery.

Further work must be performed according to the following instructions:

Replacing the VAZ 2110 alternator belt

What we need for the replacement: a good set of tools, a jack (to raise the engine) and a new belt.

Before starting work, it is advisable to treat all threaded connections on the tensioner with WD-40 liquid to loosen everything, otherwise there is a possibility of breaking the bolts.

Loosen the generator belt. The complete process of removing the tensioner is described in the article “Replacing a VAZ 2110 generator”, I recommend that you read it. After you loosen the belt, it can be easily removed from the generator pulley, but to remove it completely, you need to remove the right boot on the car body.

By removing the protective boot, you can easily pull out the worn alternator belt.

Having purchased the required size belt in advance, we install it back. If you are standing near the right fender of the car, then the letters and numbers on the belt should be read from your side, and not upside down.

All that remains is to tighten the belt and put everything back together, but this will be a little lower, and now we will carry out the replacement on VAZ cars with power steering or air conditioning.

As it turned out, everything is not so simple here. When installing power steering or air conditioning on the engine, the generator was moved slightly upward and in order to replace the belt, it must be threaded through an additional engine support.

Why they did this is not clear, but there was more work.

Here the replacement process is almost the same, but you need to tinker around with the additional engine mount.

We need to unscrew and pull out the central bolt of the support, then lift the engine a little and thread a belt into the gap between the pillow and the engine support. This method is suitable for models with installed air conditioning, but if power steering is installed, the bolt will not come out completely and will rest against the pulley.

To remove the bolt, you need to remove the pulley or completely unscrew the additional support pad. By jacking up the engine a little and turning the mount, you can thread a new belt.

I don’t know which is easier, removing the pulley or unscrewing the support, both methods are very inconvenient, so the choice is yours.

Let's go back a little to the first option if an air conditioner is installed.

You can tinker and completely unscrew the support pad, or you can completely unscrew only the central bolt.

We install a mechanical support under the car body.

Now we need to place a jack under the engine and lift it a little. The photo below shows where to install the jack, and do not forget to place a wooden block - this will prevent deformation of the oil pan.

REMOVING THE ALTERNATOR BELT

First, you need to put the vehicle on the handbrake with fourth gear engaged;
Next, open the hood and remove the protective cover from the belt, now you need to loosen the tension, then you can remove it;
Now we remove the generator drive pulley from its place, while leaving its bolt in place. Remove the vehicle from gear.
Then, you need to turn the crankshaft clockwise, while you need to keep an eye on the mark and the flywheel, they are visible in the hole in the clutch housing. You need to twist it until it becomes parallel to the middle strip of the scale;
When the mark is in the indicated position, you need to unscrew the tension roller, by the way, with the help of it the tension is released. Now we remove the damaged spare part.

The best premium timing belts

Belts in this category are produced by the world's leading companies, whose quality and reputation have already been tested by time. But you have to pay a lot of money for this. Here's what users recommend:

Gates is an industry leader

These timing belts are the best among similar products because they are manufactured in Belgium, Germany, UK and France.

The elements are of such high quality that most automakers directly order them for assembly lines for the production of new cars. But they are also supplied to the spare parts market. The timing belt is exceptionally reliable and durable.

Contitech – from a renowned tire manufacturer

These are the best timing belts from the famous tire manufacturer Continental. The Contitech brand is an offshoot of the company.

The concern's products are so popular that many car manufacturers also order them directly. Despite this, the aftermarket has a large selection of these belts. They fit various brands and models.

Pros:

long service life, often even 30% longer than stated;
the rubber contains additional components to increase wear resistance;
an outer coating made of rubberized fabric protects the internal structure from fuels and lubricants;
can carry loads 15% more than analogues;
Fits a wide range of American, Japanese and European cars.

Minuses:

average cost 1500 rubles;
there are fakes.

AMD - supplies many kits

Usually, when replacing a timing belt, it is recommended to also change the tension rollers, since their wear can contribute to accelerated failure of the new rubber drive.

In order not to look for replacement parts separately, you should pay attention to the best timing belts from the Korean manufacturer AMD, which are sold already with a complete set. This simplifies not only the search, but also helps you not to worry about the compatibility of elements in width and rotation speed.

Pros:

wide belt with markings, which can be immediately distinguished from fakes;
if supplied as a set, then there is a timing belt, a balancing belt and 3 tensioning rollers;
reliable packaging, where each part is placed in a separate box, which prevents deformation during transportation;
the installed belt works without unnecessary noise;
there is no play in the bearing in the tension roller that goes along with the belt;
are maintained for the stated period, provided they are installed correctly.

Minuses:

the cost of the set reaches 5800 rubles;
inside the box there may be a Dongil belt, from a domestic Korean company;
play occurs in the idler roller (in the bearing).

WHAT DO YOU NEED TO KNOW?

You have successfully removed the belt from your fourteenth, now in order to install a new one, you need to purchase it. You can buy a new part in any store that sells parts for domestic cars, it doesn’t cost very much, 100-400 rubles, this amount depends on the region of the country.

Important: before you run to the store, be sure to find out what the size of the alternator belt on the VAZ 2114 is in your case. If for some reason you cannot take the measurement, you can take the old one with you for demonstration and purchase the same one.

REVERSE INSTALLATION

When you have purchased a new part, it is time to figure out how to install the alternator belt. This procedure is performed in the following order:

We put the new generator belt on the camshaft pulley, now we tighten both branches;
The part that is not tensioned is tightened by the roller, put on the pump and crankshaft pulley, then we tighten the belt by reverse rotation - counterclockwise;
We turn the crankshaft about 2 turns, check the positions of the marks, they should be in the middle;
If the marks do not match, repeat the entire procedure until you can set them correctly;
You need to unscrew the crankshaft bolt and put the generator pulley in its place, then tighten it with the bolt. This is done by turning the roller counterclockwise;
