which way to tighten the generator roller on the Priora 16 valves

Replacing the alternator belt with air conditioning on a Priora, part 2

A new belt with markings suitable for the 126th engine.
When installing a belt with a tension roller, I encountered the following difficulties. My first thought was that I bought a short belt, it’s all bullshit. I loosen the top bolt of the generator with two 13mm wrenches. I hook it with a 60 cm long pipe and move the “gen” towards the roller (someone may not need this manipulation). In this position I fix the generator by tightening the bolt. After this simple procedure, we managed to put the video in its place. But the bolt could not even be tightened. After thinking a little, I came up with a small device like a crane...

The meaning is this: slightly raised and leveled the position of the bolt. By the way, do not forget about how the belt lays on the pulleys and roller; the belt should not go beyond the edge of the pulley or roller. In the end, everything started spinning and fell into place as it should. We do not tighten the bolt all the way right away, because... We still need to adjust the belt tension. We take an open-end wrench 17 and a belt tension adjustment key

Use the tension key to tighten the belt counterclockwise. Holding the key in the desired position, carefully tighten the bolt to 17. Done. We start the engine. There are no extraneous sounds, which means everything was done correctly.

Tension using adjusting bolt

Adjustment with a bolt on a VAZ-2110

This method is more progressive and is used in most modern machines. It is based on the use of a special adjusting bolt , by turning which you can adjust the position of the generator relative to the engine. The algorithm of actions in this case will be as follows:

• loosen the generator, its upper and lower fastenings;
• Using the adjusting bolt, we change the position of the generator;
• fix and tighten the generator mount.

The belt tension level in this case can be determined during the adjustment process.

Replacing the generator tension roller

It worked for exactly a year and 10 thousand mileage, and began to make noise and whistle. Perhaps the reason for this was the belt tightening, I adjusted it according to “feelings”. I thought about first disassembling the roller and filling it with lubricant, as many do when driving, but I decided to buy a new one. This time I took AT 1056-012B

I adjusted the tension using the frequency analysis method. I found the technique in the logbook: www.drive2.ru/l/471004669011820971/

I armed myself with a program from Google play, “sound spectrum analyzer” (link: play.google.com/store/app…hanik.splspectrumanalyzer), an old phone headset, bent pliers and a 17 key. I tuned it to a frequency of 135-139 Hz. After setting up, I started the car with all consumers turned on, and there was silence, but for how long)))))

If anyone needs data on frequencies (the post is old, so there is no 127 motor, but the design in the area of ​​the generator belt has not changed from 126, if I’m wrong, correct it in the comments):

Replacing the belt and tension roller of the generator drive on a Priora

In the summer, the whistling of the belt disappeared, although three months ago in winter and spring it was annoying with its squealing. The opportune moment came and I did not wait for a new howl of the alternator belt.

Purchased: Alternator belt

from tens with air conditioner Balakovo 570 rub.
Tensioner roller
Vologda 650 rub.

I disassembled the original roller, the lubricant is solid and not all around, the balls are dry. When rotated quickly, it makes a hum and there is a decent amount of play.

Replacing the belt turned out to be a hectic task; my friend Sanek changed the belt.

Briefly it looks like this: The belt needs to be threaded through the engine mount. To do this, unscrew the Trox bolts in the photo.

Using a pry bar, we lift the engine and insert a strap between the support and the body.

There was also the problem of inserting the belt onto the pulley. It's like the belt is a few mm off. smaller than the old one. Maybe I should have looked for an original belt from Priora if one exists in nature. Well, something like this, we still have to change the power steering hose and power steering fluid. See you again on the bortovik;)

How to adjust the generator roller on a Priora with your own hands

The generator belt tensioner roller is a small but very important part of the machine. If it fails, the operation of attachments and electrics is at risk. But you can diagnose, lubricate and even change a spare part yourself; it does not require much effort or serious knowledge in the automotive industry.

On Lada Prioras with air conditioning and power steering, as well as those equipped with power steering (electric or hydraulic power steering), the alternator belt is additionally maintained in an optimally tensioned state by a special roller. The Priora generator belt tension roller is an important part that ensures the operation of the attachment.

Generator malfunctions on Lada Priora

The problem with the whistling generator of the Lada Priora and the entire front-wheel drive line of cars usually lies in a collapsed front cover bearing. In this case, both the bearing itself and the belt slipping along the jammed pulley can make noise. The malfunction is determined “by eye”.

In some cases, alternator drive slippage may be caused by a misaligned alternator pulley or crankshaft pulley. The belt begins to move at an angle, touching the side surfaces. At the same time, even a new alternator belt will whistle. A breakdown can be determined by severe wear on the belt drive. The drive “eats” on the sides.

What to do in this situation? The solution depends on the identified malfunction. A loose drive should be tightened. Kalina cars and other front-wheel drive VAZA models have a tension bolt that allows you to adjust the degree of belt tension.

As already mentioned, the main difficulty lies in the location of the drive of the Priora’s additional mechanisms. The fact that it goes around the engine mount in a closed quadrangle creates serious problems during replacement. Of course, removing the rubberized strap is no problem. But installing a new one in this place is a rather complicated process.

Tools and accessories

In this case, much more tools and devices will be needed for replacement. It is best to have a full set of professional auto mechanic tools on hand. On a Priora with air conditioning or hydraulic power steering, the tension of the generator drive and other mechanisms is carried out by displacing a special eccentric roller - the tensioner roller. A special key is also required to adjust it. When replacing the belt, you will have to lift the entire engine so that it comes out of the front mounting stud of the engine mount. Therefore, it is necessary either to have a professional car mechanic jack on hand, or to work in a room equipped with special hoists for removing the motor or, in extreme cases, with a hydraulic or electric lift.

ALTERNATOR BELT TENSION ROLLER FOR VEHICLES WITH STEERING OR AIR CONDITIONING

The Priora, equipped with various options, has an alternator belt more than a meter long. It passes through four reference points. Three of them are pulleys. The first is the engine drive pulley and the second is the generator and power steering pump or air conditioning compressor. The fourth point is the tension roller itself. This simple mechanism is made in the form of a regular rolling bearing, with an eccentric base. That is, when turning it around its axis, thanks to the hole for the bolt, located not in the center of the bearing, but offset to the edge, the protruding part can tighten or loosen the drive belt of all additional Priora mechanisms.

Tensioning the alternator belt: a guide for car enthusiasts

The distinctive features of the Priora from previous modifications of the manufacturer are noticeable immediately, literally as soon as we open the hood. Here the new owner of the Lada will have to learn a lot again. This seemingly not very complicated procedure, which allows you to tighten the alternator belt in a Priora car to the required limit, will require considerable effort.

The peculiarity of new car models is that the ability to choose a car equipped with optional equipment is already present as standard. So in the “base” “Priora” can already be equipped with power steering or air conditioning.

Naturally, driving the car becomes even more convenient, but the recompense for comfort in this model is a more complex design of the generator belt drive. After all, the belt itself on a Priora car, which has air conditioning or power steering, is significantly longer, has a more complex trajectory, is serviced and replaced according to completely different rules.

What to do if the alternator belt breaks

Anything can happen on the road, and we cannot exclude those moments when, for some reason, the generator drive breaks. If this happens, you can carry out a simple procedure to replace it with improvised means and go to a service station or auto store to purchase an original spare part.

A strong rope or women's tights folded into a narrow strip are suitable as a substitute for the drive.

• We lower the tensioner to the limit to facilitate installation of the temporary drive.
• We put a rope on all the rollers.
• We return the tensioner to its original position, checking the deflection of the rope (it should not be more than one centimeter).

On cars without power steering or air conditioning, the replacement method is slightly different:

• Loosen the top nut of the generator.
• We tighten the tension bolt to bring the generator closer to the engine.
• We install the rope.
• We unscrew the tension bolt, moving the electric generator away from the engine.
• Having achieved the required tension, tighten the upper fixing nut.

If this happens within the city, and the car has a good battery, you can immediately go to a repair shop or store. The battery charge lasts for 20-40 km, but to be sure of covering such a distance, you should turn off all electrical appliances.

Tensioning the timing belt on a Priora: user instructions

In addition to the alternator belt in a Priora car, another important component is the timing belt. For this reason, many car enthusiasts are wondering how to tighten the timing belt on a Priora? It is not difficult to carry out this procedure; it is enough to prepare a tool: a “5” hexagon, a “17” and “15” head.

Before tightening the Priora timing belt, you should:

— unscrew the two screws securing the cover;

— remove the bottom cover covering the timing drive;

— insert the tips of the pliers into the grooves of the outer race of the tension roller in order to remove the locking rings.

- tighten the belt by turning the tension roller directly with pliers, counterclockwise.

— these actions are performed until the cutout of the outer race is aligned with the rectangular protrusion of its inner sleeve;

— after the above steps, the roller mounting bolt is tightened with a wrench;

— we check that the marks on the camshafts and crankshaft are aligned, as well as the cutout matches the mark on the tension roller. If the marks do not match, you should repeat the operation to tension the timing belt.

From the above it follows that tightening the alternator belt is as simple as tightening the handbrake on a Priora. An experienced driver will be able to do this quickly and without unnecessary movements. Care and the correct sequence of actions when tensioning the alternator belt will preserve its functionality for a long time of operation, and your car will always remain a PRIORITY.

Replacing the alternator belt of a Lada Priora with air conditioning and power steering

Replacing the alternator belt of a Lada Priora with air conditioning

A recent inspection revealed defects in the alternator belt. The decision to replace was not long in coming. At 99, the belt was changed within 1 minute. I spent about 1 hour here.

Unscrew the two bolts securing the right engine mount. Here was the first ambush, the bolts were star-shaped, I had to buy an E10 head.

We place a stop under the hole in the standard protection, where the drain plug is, and lower the jack, hanging the engine. Under the hole formed between the right engine mount and the bracket, remove the old belt. First unscrew the tension roller with a 17 key.

OLD BELT, TRACES OF DEFECTS AND BELT SIZE VISIBLE

Here I would like to dwell in more detail. About the belt size. How to choose? In markets and shops, 90% said take 6rk1125, the remaining 10% 6rk1115. And one good person said the following and I advise you too

1. Look at the old belt, maybe the size is the same. 2. Take 2 belts, with the condition of returning one of them.

In my case, the first option worked. I purchased a German 6rk1115 belt

Just a note: according to the manual you had to buy 6rk1125.

We install the new belt in the reverse order, assemble the units, simultaneously check the tension roller for defects, and, if necessary, change it.

Adjusting the belt tension

I forgot that I gave the key for such rollers to the owner of 99. I used a circlip remover to tighten it.

When properly tensioned, the belt should not flex more than 8 mm.

In fact, I expected big problems, but everything went like clockwork

Replacing the alternator belt on a Priora with Panasonic air conditioning

I will try to tell you in more detail about this rather simple process, as it seems at first glance, and for which some services are trying to rip off more money, they say, you need to remove the pillow, and all that. I carried out the replacement on the ground without a lift, and the car does not have crankcase protection, which, of course, will have to be removed when replacing. We will need a belt (I will also write about them in more detail.) two jacks, preferably one, a rolling one or just a hydraulic one (since there is no special place to turn the usual handle under the car), a ratchet, a head for 17, a ratchet extension for 15, and a cardan , as well as a wrench for tensioning the roller and a screwdriver for unscrewing the boot (it depends on which screws are screwed on). We remove the wheel.

Remove the tension roller.

This view opens up to us

We roll the jack under the crankcase and push it a little. You don't need to lift it too much just yet.

Then we completely unscrew the nut number 17. There is absolutely no need to unscrew the mounting of the airbag to the body, as many people do, the metal there is thin, the thread can only be tightened once.

It will look like this

Next we unscrew the pillow bolt by 15. It is quite long, but there is no need to unscrew it all the way. About half, maybe a little more

For clarity, I took this photo for those who don’t know, it can be very useful. Between the pillow and the bracket there is an intricate nut that fits into the groove of the bracket, thereby we can easily unscrew the bolt from the bottom of the pillow.

Now the manipulations with the jacks begin. We lift the car body in order to get the distance to push the belt through the cushion.

But you shouldn’t get carried away as you might break the guitar. since the body goes to the top, and the engine remains below. We pick it up and look at the guitar: as soon as it becomes a pity, that means that’s enough. For convenience, you can look at the bottom one - they bend the same way.

We insert a belt into the gap that appears between the pillow and the bracket, lift the engine a little and pull it out from below.

We push the new one behind the cushion, lower the engine a little and push it into its place.

Raise the car and lower the engine slightly. You can do both, you can do one thing or the other, the main thing is to look at the guitar. We put the bracket back on this nut and make sure it fits into the grooves of the bracket

Next, tighten the pillow bolt all the way. If the bracket is not placed on the cushion, most likely the bolt will spin, and holding that nut is extremely inconvenient and a second person will be needed. Also, make sure that the pillow remains standing as it was, so that it does not turn. I don’t know what effect this will have, but I’m in favor of leaving it as it was.

Once we tighten the bottom bolt to 15, carefully lower the engine onto this bolt so that it looks like in the photo, and tighten the nut to 17 until it melts.

We put the belt with the roller in place. we pull. install the boot and wheel. The result should look like this.

Here it is not yet stretched.

It took me about 30 minutes to replace the belt and take pictures along the way. I spent another 30 minutes tightening it and checking the charging with and without load. In general, nothing complicated. Once you change it, it will be easier later. I seem to have described all the nuances.

And now about belts from personal experience: I installed a Contitech belt. This belt length is perfect for a Priora with Panasonic air conditioning. I haven’t encountered any problems with other air conditioning systems, so I can’t say anything. but you can also put 6pk1120, it’s a little shorter. I also read that they stuff in 6pk1115, but there you already need to move the generator towards the engine. and it will be possible to tighten it, but it will be more difficult. This is one of the easy options. 25 and 20 I set the belt for myself. fit without problems. I didn’t see much point in making the belt shorter. Well, that seems to be all.

General questions about working with the Grant generator

How to adjust headlights with your own hands

Let's consider general questions: everything except replacement.

Tension check

There are two approaches: visual assessment and physical.

Visual assessment of condition:

1. the car is on a flat surface, the gear is in neutral, the handbrake is off, the hood is open;
2. We don’t start the car - we put it in 5th gear;
3. We opened the hood and found a generator: we push the car back, resting against the bumper;
4. We inspect the required part along its entire length: are there any breaks or cracks? It needs to be changed.

Poor quality will lead to unexpected problems on the way. Physical assessment:

• if you have a tool that measures pressure force: press the belt with a force of 10 kg*s - the deflection should be no more than 10 mm;
• there is no special tool: we try to turn it across - it should turn no more than 90 degrees.

How to tighten the alternator belt on a Grant

This section applies only to machines with a tensioner. No - change the part or see above how to install it.

Subsequence:

1. we use ring wrenches 8, 19;
2. Throw key 19 onto the lead screw;
3. wrench 8 for locknut;
4. we touch;
5. Now you can turn the lead screw: clockwise to loosen, counterclockwise to tighten;
6. got the desired result - tighten the locknut.

It is better to take ring wrenches, since a head with a ratchet or a wrench will not work.

When to change: technical regulations for replacing a VAZ 2190 belt

AvtoVAZ requires checking the condition of this part every 15,000 kilometers.

Replacement is required every 30,000 kilometers, regardless of condition.

How to remove a generator on a Grant

It needs to be removed for repairs, replacement of bearings or rollers.

The step-by-step process involves:

1. remove the negative terminal from the battery;
2. working with the generator: disconnect the wiring harness from it;
3. remove the cover of the power wire nut, remove the nut and remove the wire from the bolt;
4. unscrew and pull out the upper and lower fastening bolts - to work with the lower one, you may need to climb into a hole, throw off the tin protection of the internal combustion engine and dismantle it from below;
5. move the part to the right mudguard, remove the belt, and remove it.

You can do without a hole. Example:

How to replace and tension the alternator belt on Lada Priora

The Lada Priora car is very popular. This is another proof that Russian cars can be of high quality. They actually boast good comfort, handling, and attractive appearance. The differences between the new model and previously released cars are primarily hidden in the engine compartment. Here everything is located completely differently. Therefore, even experienced craftsmen do not always know how to replace the alternator belt on a Priora, as well as how to tension it.

The new Priors are equipped with a large number of systems and are also available with an impressive list of additional equipment. Read more about the new generation Lada Priora 2022 in our article.

Although the installation of air conditioning and power steering on the Priora had a positive effect on comfort, as a result of such changes, access to the generator became quite difficult. The alternator belt of a Priora with power steering or air conditioning is longer than the regular version of the car, so we will consider the procedure for replacing the alternator belt for two modifications.

As a rule, the need to tension the generator belt arises due to its wear during use, as well as a decrease in the quality of adhesion of the belt surface to the planes of the generator rollers and pulleys.

If the alternator belt on your beloved Lada Priora begins to whistle, you will have to start tightening it. You can tighten the alternator belt on the Priora using a 19mm wrench, as well as a special wrench for the pulley. He is shown in the photo below.

The belt tension is performed as follows:

If the procedure is performed correctly in the basic version of the model, in the longest section between the pulleys the belt should bend by about 10 mm. In the case of a version equipped with air conditioning or power steering, you need to tighten the belt a little more. As a rule, this procedure is trusted to specialists.

According to official data, the belt should be replaced every 60 thousand kilometers traveled. If the car is used very rarely, the alternator belt on the Lada Priora needs to be changed every two years, and in this case it does not depend on the mileage.

Before replacing the belt, you must place the vehicle in an inspection pit. Next comes the preparation of the following tool:

First you need to loosen the nut using a 13mm wrench (see photo).

Next, you need to unscrew the bolt intended for adjustment, using a 10mm wrench (more details in the photo below).

Next, we move the generator itself in the direction of the power unit. Unscrew the front right wheel and remove it. Then we perform similar actions with the fender liner. Only then can you remove the old alternator belt and replace it.

After installing the new belt, you must perform all steps in reverse order. Do not forget to correctly adjust the tension of the alternator belt on the Priora. If the belt is too loose, the battery may not charge fully, and if the belt is too tight, it will cause the alternator bearings to fail too quickly.

Since the power steering pulley in this modification of the model is installed at a low height, the designers decided to run the generator belt around the support of the car’s power unit. This means that in such a machine, replacing the alternator belt can only be carried out under appropriate conditions.

Next, we will look at the procedure for replacing the alternator belt on a Priora with air conditioning. First you need to prepare the following tool:

New Lada: Updated Lada Priora: what's new? - KOLESA.ru - automobile magazine First, we use WD40 to wet the bolts securing the engine mount and bracket.

After about 10-15 minutes, you need to unscrew the bracket nut, after which we lift the front right wheel using a jack. Then you need to place something suitable under the motor and remove the wheel.

Next, you need to slightly lower the car, unscrew the tension roller, bend the belt and unscrew the bolts that secure the airbag.

After this, you need to lower the car so that the engine begins to hang out. The cushion should be moved towards the engine, which is enough to remove the alternator belt and install a new one.

At the final stage, you need to jack up the car to lower the engine. During the procedure, it is necessary to control the position of the pillow, as well as the generator belt, which we replaced. Then do not forget to tighten the pillow bolts, as well as the nut that secures the bracket.

As you can see, those who want to change the alternator belt on a Priora will have to work a little, but the reward will be the correct operation of all car systems.

TENSIONER FOR PRIORA AND KALINA NOT EQUIPPED WITH OPTIONS

On the Priora, which does not have power steering or air conditioning, the belt is much shorter. It works on only two points: the crankshaft pulley and the generator pulley. The latest samples are equipped with a tensioning system similar to the VAZ Kalina. That is, if on other VAZ cars the tension is done by moving the generator itself, then on the Priora, a plastic roller of the tension system presses on the drive from above. A special tensioning mechanism is installed to move the roller. It consists of several parts:

The entire system is clearly visible in the photo. To adjust the drive and replace the tensioner, the following keys are needed. Slip on 19, end and socket on 13 and any wrench on 8. First, loosen the bolt and nut holding the movable platform with the roller with a wrench on 13. Then release the lock nut securing the adjusting rod using a wrench on 19. Using a wrench or socket on 8, unscrew the adjusting rod cravings The generator remains motionless. When the belt is loose, unscrew the bolt with the bushing on which the desired part is attached. Now remove the roller and install a new one in its place.

Check the free rotation of the tensioner for the generator drive and, having tightened the rod to the normal state of the drive, securely fix all the fasteners.

How to determine the need for replacement or adjustment

The condition and tension of the belt must be checked at least once a quarter.

This will allow you to quickly detect weak tension or damage to the belt. A whistle that appears when starting the engine and accelerating the car indicates weak belt tension. Rapid battery discharge (as well as weak charging current) may also indicate a loose alternator belt. The service life of a high-quality alternator belt is 40–60 thousand kilometers or 2 years. After this, the belt must be replaced, even if it looks normal. If cracks or breaks appear on the belt, it must be replaced, regardless of mileage. To determine the condition of the belt, it is necessary to carry out diagnostics.

How to lubricate the alternator belt tensioner roller

Lubrication of the roller is necessary so that the bearing moves more easily and does not create additional resistance to the movement of the drive. This can be done without removing the roller itself. Initially, select a lubricant:

• lithium lubricants (most often used “Litol-24” or “Ciatim-221”);
• CV joint-4 is best manifested in medium and high temperature conditions;
• synthetic lubricants are not washed out by water, therefore they are recommended for regions with high humidity.

Having chosen the product, you can begin to lubricate the roller:

1. Using a flathead screwdriver, carefully remove the boot from the tensioner.
2. Fill the syringe with no more than 1 cubic meter of lubricant.
3. Insert the needle into the gap from the boot and move it around the entire circle, smoothly squeezing out the contents of the syringe.
4. Start the engine so that the lubricant is evenly distributed on the roller.

After this, turn off the engine and replace the boot. Excess lubricant should be carefully removed with a cloth or sponge so that it does not get on the belt during operation.

Sn9shimo

The belt should not rotate more than 90°. Otherwise, the belt tension needs to be adjusted. To tighten the belt, turn the tension roller counterclockwise, and to loosen it, turn it clockwise. To do this, insert a special key into the holes of the tension roller in the form of two rods with a diameter of 4 mm, welded to the base of the key (the distance between the rods is 18 mm). You can use the key for the old-style timing belt tension roller, installed on all front-wheel drive VAZ cars. If you do not have a special key, you can insert two pins (screws) with a diameter of 4 mm into the holes of the tension roller. Using the screwdriver shaft located between the pins, turn the roller.

Does it whistle and skid? Diagnosing the alternator belt

As long as the belt works normally and adequately, we do not notice it. The generator operates in normal mode and provides reliable power supply to the on-board electrical network and recharges the battery .

This is evidenced by stable ammeter readings and quiet engine operation. However, one fine day the belt makes itself known with a high-pitched squeal or lack of charging current to the battery. This will be indicated by the ammeter on the instrument panel and the battery charging indicator lamp.

Alternator drive belt

Open the hood and see if the belt is in place at all. Some unfortunate drivers' belts break while on the road, and it is quite difficult to find a replacement.

On the VAZ-2114, the engine is located transversely, so the alternator belt is located on the opposite side of the gearbox, to the right in the direction of travel. If the belt is in place, it is enough to tighten it and the operation of the on-board electrical system will stabilize.

To do this, you will need only two keys from the standard set of tools - 10 and 13, but it is more convenient to use heads with a ratchet. And preferably a lever! Everything is ready, you can start working.

How to tighten the alternator belt on a VAZ-2114

The procedure for tightening and adjusting the belt will take about five minutes, but it is important to know a few subtleties that will save you from problems on the road in the future.

The first subtlety is that over-tightening the belt is just as dangerous as under-tightening it. You can ruin the generator bearings, and replacing them will cost five times more than the most expensive belt. In addition, to replace the bearings you will have to completely disassemble the generator or change it altogether. Tightening the belt is unacceptable!

The procedure for tightening a belt is simple and even a child can handle it if you follow a simple algorithm and do not break a certain sequence:

Generator drive diagram: 1 - mounting bracket to the engine block; 2 — connection of the generator with the bracket; 3 — tension screw; 4 — generator set pulley; 5 - axial screw; 5 - drive belt; 6 — generator pulley on the crankshaft.

Checking the belt tension after tightening

When is it necessary to tighten?

Actually, the reasons why the belt needs to be tightened are simple - the generator does not produce enough current to operate all consumers on board and cannot charge the battery. The primary sign of weak belt tension will be a whistling sound from under the hood. Nevertheless, the belt can whistle when water gets in, sometimes when the pulleys become oily, and even less often when the generator bearings fail. If the belt cannot be tensioned or the adjustment rail does not allow the generator to be moved further, the belt must be replaced.

Subtlety two. Rubber tends to crack, and even taking into account the reinforced structure of the drive belt, it will not last long with cracks.

The most common mistake is storing a spare belt under the hood, in one of the niches. Due to constant high temperature, even the best and new belt can become unusable in just a couple of months if it lies as a dead weight under the hood. New or spare belts should be stored either in the garage or in the trunk.

Symptoms of malfunction and their elimination

You can determine whether a replacement is needed or whether you can simply tighten the power steering belt with air conditioning on the Priora 16 valves only after inspecting this component. To do this, just open the hood and examine the belt; it is located next to the right front wheel. There are signs that indicate it's time to check the alternator belt: something whistling and squeaking from under the hood.

The reasons may be the following:

• Antifreeze, oil or other working fluids have come into contact with the generator pulley or belt.
• The belt is worn out - you can tell by its appearance.
• The tension has dropped - in this case, the component must be tightened.
• The bearing in the generator is worn out.

When the belt whistles in a Priora with 16 valves, it’s time to carry out diagnostics. If there are cracks, tears or other serious damage on its surface, then replacement is required. If the generator component with hydraulic booster and air conditioning looks normal, you should check its tension; the optimal level of deflection is 6-8 mm - you need to press the component in the middle between the generator and the pulleys.

Are there visible coolant or engine oil stains on the surface? If the contamination is not significant, they can be cleaned. If the liquid has penetrated into the material, cleaning will not bring any results; replacement is needed. If the component is well tensioned and no damage or stains are visible, then you should move on to checking the bearings. They may need to be changed.
