According to the maintenance regulations for Lade Priore Timing belt replacement is provided during mileage every 200,000 km, and checking the condition of the belt and its tension must be done every 105,000 km. But, according to reviews from car owners, such a mileage is only possible on a belt installed from the factory.
After the first replacement of the timing belt and rollers VAZ 217030 (Lada Priora) 1.6 16 valves , it is necessary to reduce this regulation by 3 times . It is recommended to change the timing belt and rollers at a mileage of 50,000 km - 60,000 km , and inspect the belt every 25,000 km - 30,000 km .
If you detect even the slightest cracks on the belt or a hum in the roller bearings, it is necessary to urgently replace the rollers and toothed belt, since if the timing belt breaks, there are 16 valves on the 1.6 , the valves will bend and it will be necessary to repair the engine.
Timing belt tensioner rollers for VAZ (Lada) Priora
for repair of VAZ (Lada) Priora
It was in trial, it ended after 2 years, I just bought trw, there is a little play and jamming from the factory.
The problem with the rollers does not last even 10,000 km and they begin to make noise and make other indecent sounds. But today it just killed me that I put on a new video and went and heard what kind of buzz it was making.
The original Conder roller clicked—you can hear clicks when the hood is open when it’s hot. I bought a Trialli video - I know China, but it looks good - I returned it to the store after 5 days. Ordered and installed Gates - 7 days, returned.
I bought it at the VBF store, who knows if it’s a fake or not, the balls don’t click, but the rustling noise persists after 2 days.
Over the weekend I replaced the timing belt rollers because... There was noise from the timing belt. After checking, it turned out that the roller bearings were noisy. My father and I took off the belt and checked the bearings. Both bearings had play and were dry. The support one even wedged a little.
We went to get new ones, but finding normal rollers turned out to be problematic. Everything they looked at was of dubious origin and did not inspire confidence, and was sold together with a belt (Gates). My belt was in excellent condition, so I was not going to overpay for it.
After visiting 5 stores, we found the rollers separately from the Trialli belt. This is their original number (21216-1006135, 21216-1006238). After installation the noise disappeared. Belt tension roller kit, support/tensioner Trialli Linea Qualita.
I installed a Trialli timing belt tensioner pulley on a chisel (I know it’s China, but there was no choice, but it was necessary urgently) - at first glance, the quality was good, there were no complaints about the appearance or rotation. True, in terms of service life - I sold the car 2tkm after the replacement.
Those who installed it are all happy. They have a double row support bearing.
The scientist, through bitter experience, after repairing the “head” due to the wedge of the roller, decided, out of harm’s way, to change the rollers between belt replacements. The last “arrival” was at 97 thousand. 35 have passed. It’s time!)
It is worth noting that the dismantled Gates rollers were in very good condition. Now they installed Andykar.
I have a Priora with power steering, so I was tired of changing the tensioner pulley of the alternator belt! I bought Ladovsky and Trially and Gates to no avail! They don't walk very well! They start rustling loudly almost from the very beginning! I found a video from the cartridge company!
It is stated in the description that the bearing is from NSK! I installed it, so far so good! I was surprised that the surface itself is poly-wedge steel!

Self-replacement of Priora timing belt 16 valves
When installing the belt, careful and precise approach is required. If the belt is replaced incorrectly, a mismatch occurs in the actions of the shaft and camshafts. After which the pistons will contact the valves of the cylinder head. When the valve stems bend, compression may be lost. After which the valves and other mechanisms will have to be changed.
you need to turn the crankshaft
If you need to turn the entire timing mechanism during work, then you can only turn the entire system using the crankshaft. When scrolling the camshaft, you can damage the entire system, since the crankshaft is the leading one in the mechanism.
no need to crank the camshaft

Signs of the need for internal combustion engine repair
The reasons why the operation of the engine is disrupted are arranged in a small list, starting with refusal to start and ending with floating idle speed (this problem was removed on the 127 “engine”). Not all breakdowns end in capital damage - sometimes it’s enough to add oil, sometimes it’s enough to adjust the ECU settings.
Compression reduction
A decrease in cylinder compression below 16 atmospheres is a bad sign. Such a high limit corresponds to a compression ratio of 11.
Knocks in the engine
Engine knocks can come from several points. These could be hydraulic compressors, timing belt rollers or pins. The knocking noise could also be caused by low oil level. The answer to the question will be given by a thorough detailed inspection of all parts of the unit and checking the oil level.
Blue smoke from the exhaust pipe
The blue smoke that comes from the exhaust pipe appears when oil enters the combustion chamber. It can leak either from the valves or from under the piston. The result is the same: the oil is eaten up and blue smoke pours out of the chimney. Once the leak is located, half the problem will already be solved.
Troit motor
Sometimes in the cold the engine may stall - don’t be alarmed by this, because it may simply be one of the spark plugs that fails. In this case, we advise you to simply restart the engine and it will stop running.
How much does it cost to overhaul a Priora engine - average price
Self-repair of a Priora engine with 16 valves costs an average of 16-20 thousand rubles. The cost depends on the severity of the breakdown and may be lower or higher than this average range. Repairing a Priora engine can be entrusted to the wrong hands, but then you will have to pay for the work - sometimes the cost of repairs reaches as much as 40 thousand rubles.
This is an unreasonably inflated figure, because, as practice shows, you can rebuild the engine on a Priora, working at a moderate pace, in just three days - and three days of work is definitely not worth that kind of money. Don’t be afraid of not being able to cope - your Lada is easy to repair, and using the advice and “tutorials”, you will conquer even such a task that is impossible at first glance.
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.
Loosen the lower generator mounting bolt
Loosen the top nut securing the generator
Tighten the generator belt
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.
When to change
The manufacturer provides a 100,000 km warranty on a new belt. But the quality of the tension and deflection rollers leaves much to be desired. Therefore, based on life experience, the timing belt along with the support rollers should be changed every 50,000 km. This will help avoid tragic consequences resulting from a timing belt break or failure of one of the rollers.
Also, after 50,000 km, it is necessary to check the coolant pump (pump) for leaks, play and squeaks. If necessary, the pump must be replaced. When a vehicle travels more than 100,000 km, the coolant pump must be replaced.
About engines
The car was produced from 2007 to 2022, it replaced the VAZ 2110. The first Priors were equipped with engines from the previous model with some modifications, they had an index of 21116. There were 8 valves in the cylinder head, the timing drive was with a toothed belt. Experts note that this engine has good environmental performance, reduced operating noise, and increased power. The engine is of in-line type, the power system uses an injector. As a disadvantage, a decrease in the engine life compared to the indicators declared by the manufacturer was noted.
Engine 21126
After further modernization of the engine, version 21126 appeared, which is based on the previous cylinder block from the VAZ 21083, it received a twin-shaft cylinder head. The new Priora power unit with 16 valves has become a little more complex, but has received an increase in power and has become even more economical. The valve mechanism of this engine received a modified drive design; it was still belt driven. The length of the drive has become longer, so an automatic toothed belt tensioning system has been introduced. Somewhat later, the car was equipped with engines such as VAZ 21127, VAZ 21128, which were a modernized version of the VAZ 21126.
Are the valves bending?
Gasoline internal combustion engines of modern cars run on high-quality gasoline with an octane rating of 95 and higher. These types of fuel require a high compression ratio at the end of the piston stroke. Designers achieve this by reducing the combustion chamber in the cylinder head. This feature of the engine design carries the risk of damage to the valves, in some cases, pistons, and connecting rods in the engine. This can happen when the belt breaks or its teeth are cut off.
VAZ 21083 engines did not have such a problem since recesses for the valve heads were cast in the pistons. Therefore, their meeting with the pistons was not dangerous. On the engines of the new series, this was abandoned in order to increase efficiency, power, and other engine indicators. The designers believe that if the timing mechanism drive parts on the Priora are replaced in a timely manner, there will be no such problems. Every owner of a 16-valve Priora must remember that when the timing belt breaks, the valves are damaged. To the question of whether the valves on the 16 valve Priora are bent, the answer will only be in the affirmative, yes.
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.
