A slightly battered VAZ 2110 with an 8-valve engine, replacing the timing belt, tension pulley and pump. There are 150 thousand kilometers on the odometer, but judging by the condition, it has definitely been damaged a couple of times. The last replacement of the timing belt, according to the client, was almost 50 thousand km ago, immediately after the purchase. The frequency of replacing the timing belt on VAZ 2110 8-valve engines is 60 thousand kilometers or four years of operation. The replacement interval can be increased to 80 thousand kilometers, with periodic monitoring of the condition of the gas distribution mechanism elements.
If the timing belt on an eight-valve VAZ 2110 engine breaks, the valve does not bend.
Step-by-step instructions for replacing the timing belt
- Be sure to open the hood.)
Engine 8 valves. - Loosen the locking nut of the generator tensioning device (key 13) and unscrew the adjusting screw (head 10) to the maximum. We take the generator to the cylinder block and remove the generator drive belt.
- We dismantle the plastic protective cover of the timing belt by unscrewing three bolts (10 wrench).

Set top dead center (TDC)
- We turn the crankshaft clockwise until the mark on the camshaft gear pulley and the curved edge on the metal casing coincide.
Camshaft mark. - We remove the generator belt drive pulley by unscrewing the bolt by 17, you will need a wrench with an extension and a pipe as a lever, since the bolt must be well tightened.
- The mark on the crankshaft toothed pulley should also coincide with the low cast mark on the oil pump.
Crankshaft mark. - We dismantle the tension roller together with the timing belt by unscrewing the nut (head 17). Next, unscrew the bolt 17 and remove the camshaft pulley. To avoid losing the key, you can secure it with electrical tape. It is advisable to replace the camshaft and crankshaft pulley.
Fastening the tension roller.
Replacing the pump
- We remove the metal protection, unscrew the 10 nut on top and the three bolts on the bottom securing the water pump. We take out the old water pump.
Pump mount. - Before installing a new pump, apply a thin layer of sealant to its gasket. After installing the pump in place evenly, in several passes, tighten its mounting bolts.
When does a belt need to be replaced on a Priora: possible consequences
It is recommended to replace the timing belt every 30 - 45 thousand kilometers. Of course, the probability of a belt breaking with such a mileage is very low, but the indicated mileage is the resource of the product. There are many cases where motorists clock twice the mileage indicated above on the tachometer, and have never changed the belt. The serviceability of the product in question is measured not only by its integrity. During operation, it stretches, therefore the quality of engagement decreases and the likelihood of slipping increases.
Timing belt with worn teeth: what can happen if the product is not replaced in a timely manner
This is interesting! The service life of the timing belt is influenced by various factors: the nature of the ride, the quality of the product, the ingress of foreign liquids and objects onto the belt drive, etc. It is impossible to indicate the exact mileage that a timing belt will last. To avoid having to go to a service station for major repairs, it is recommended to monitor the operating time of the product on a car such as the Priora.
Signs that the timing belt on a Priora needs to be replaced are the following factors:
- presence of extraneous noise when the engine is running;
- changing the color of exhaust gases;
- problems when starting the engine;
- extraneous vibration.

Replacing the timing belt on a Priora 16 valve may be necessary much earlier than at 30-45 thousand km. This is due to oil, dirt and antifreeze getting on the belt drive. Antifreeze or coolant poses a particular danger to the integrity of a rubber product. If a coolant leak occurs, which is caused by a leak in the pump gasket or failure of the pump, then the service life of the rubber product is reduced tenfold. If a coolant leak is detected, the causes should be promptly identified and eliminated. If the cause is a violation of the integrity of the pump or gasket, then the timing belt will need to be replaced at the same time. If there are problems with the strength of the belt at high speeds, irreparable consequences may occur in the form of broken pistons and deformation of connecting rods.
Installing a new timing belt
- A new timing kit from Gates was purchased.
- The kit includes a toothed belt and a tension roller.
VAZ 2110 timing kit. - We check that all marks match. We start installing the belt from the crankshaft pulley, then put it on the camshaft pulley, pump and tension roller. We make sure that the descending branch of the belt between the pulleys is tensioned.
- We tighten the timing belt by turning the tension roller counterclockwise. The optimal tension is considered if, with the effort of two fingers, we can turn the belt at the longest section by a maximum of 90 degrees.
We also check the tension during periodic monitoring.
Tighten the tension roller fastening.
- We install all elements in the reverse order of removal.
Do not overtighten the timing belt as this will apply increased force to the pump bearing and it will not last for a long time.
The entire operation took approximately 30 minutes. Since this procedure does not require hanging the engine, you can do it yourself in the field, and if the pump does not change, then you don’t even need to remove the wheel.
How to check tension
At the end of the work, it is necessary to adjust the tension of the timing belt drive on the Priora. The adjustment is made as follows:
- Using a special wrench, you need to turn the tensioner pulley counterclockwise.
Tensioner adjustment key
You can check the tension by applying force to a rubber product weighing 10 kg. The deviation value should not exceed 5-7 mm.
When tightening the pulley and roller bolts, it is recommended to use a torque wrench. The tightening torque for each element is equal to the following values:
- for the tension roller – 35-41 Nm;
- thrust roller – 105-110 Nm;
- pump mounting bolts – 15-20 Nm.
After adjustment, you can put the protective cover back in place. Finally, the generator belt tensioner roller is installed, as well as the belt itself. It is also recommended to replace these elements with new ones. Finally, do not forget to fill the coolant before starting the engine.
Upon completion of the work done, you can start the engine and check its operation. If the marks are correctly set, the engine will start the first time the key is turned in the ignition switch. In this case, the engine should operate evenly and keep the speed in the region of 800-900 rpm. Listen to the timing belt drive. There should be no extraneous sounds or noises. The presence of a whistle or hum indicates that the tensioner is too tight and needs to be loosened.
Help in choosing a timing belt and rollers
The reliability, efficiency and operating life of the motor depend on the quality of the rollers and belts chosen for replacement.
Research shows that the cost of a belt is from 450 rubles, and rollers will cost you at least 600 rubles.
When buying spare parts, be guided by the opinions of VAZ 2110 car owners. There are many forums. Also consult with specialists at the service station. They will be able to give professional advice, or even order quality components for you.
When is it necessary to replace the timing belt and set the marks?
Without exaggeration, a worn timing belt can be called a “ticking time bomb.”
The importance of this element in the car system is difficult to overestimate. Usually it is made of high-quality rubber, the service life of which is designed for 50-60 thousand kilometers.
But, if the vehicle is operated in unfavorable conditions, the replacement interval will be different.
In most cases, the replacement interval is indicated by the manufacturer in the documentation for the vehicle. In addition to the resource built into the belt, it is worth considering the following factors that shorten the service life of the rubber element:

- Engine oil getting on the surface of the timing belt
- Leakage of the front crankshaft oil seal
- Tension roller malfunction
- Pump jamming
As you can see, there can be a sufficient number of breakdowns in the car system that directly affect the service life of the belt. If the scheduled replacement time has come, or its resource has been prematurely exhausted, it is not enough to simply replace the old mechanism with a new one - you also need to take care of the correct installation. To successfully do all the work, it is enough to arm yourself with the necessary tools and know how to align the belt with the marks.
Signs of a faulty timing belt and their causes
Some experts say that belt replacement is required after approximately 75,000 km under standard vehicle operating conditions, or after 60,000 km under heavy-duty conditions. At the same time, experts often recommend periodically diagnosing the car anyway, since in fact, replacing it with a VAZ-2114 may be necessary earlier due to the following defects:
- The appearance of swelling;
- Cracks;
- Various structural defects due to constant corrosion by oil;
- Fraying the ends.
If any of these defects appear, we can confidently say that an urgent replacement of the timing belt in the VAZ-2114 is necessary. When it finally breaks while driving along a highway or road, this can ultimately cause very serious consequences, since the valves collide with the pistons and, accordingly, become deformed, which will require extremely expensive repair work.
In the vast majority of cases, this all arises due to:
- Unskillful or aggressive driving;
- Purchase of low-quality consumables;
- Operation of transport in rather specific climatic conditions;
- Incorrect installation of the belt during the previous replacement.
Noticing that the engine has stopped starting normally, stalls during operation, or a phase sensor error appears, all this indicates a malfunction with the timing belt. If you plan to replace the timing belt in a VAZ-2114 yourself, there will be no difficulties if you follow simple instructions.
Special attention should be paid to the fact that often the cause of belt chafing is the rollers, and this is quite easy to determine, since it has noticeable damage on one side, which is why it eventually breaks. To avoid such troubles, it is recommended to check the condition of the rollers from time to time.
How long does it take to change the Priora timing belt?
How long does it take to change Priora timing belt
Tell me when it is necessary to change the timing belt, on the Priora they say that the service life is longer than on the tens of 16s, or are they chatting again? And it’s true that the bend is against the traffic police and traffic police
On the Priora, the warranty on the belt is about 100 tons, there is a self-tensioning roller (Chinese) so there are no signs from the belt, the roller makes noise but is different. The valves are bent. So the question is who to trust
According to prior, the plant has already changed the mileage before replacing the belt to 60,000 km.
YOU ARE INTO A SUPER GAME. :):):):):) Yes . he walks around on it a little more. and its replacement has become almost 10 times more expensive! And the valves bend there, like on 1.5 16v.
The valve bends 100%, the timing belt from the factory is designed for 200t.km, you just need to periodically look after it, the belt breaks in most cases - the pump or roller falls apart.

Working with a 16-valve engine
Replacing the drive on an 8-valve engine
Auto mechanics recommend carrying out a scheduled technical inspection of the Lada Priora timing belt every month. This part must be replaced if cracks, abrasions, cuts or other defects appear. Replacing the alternator belt on a Priora is carried out when a high-frequency whistle appears as a result of turning on electrical appliances.

Causes of belt breakage
One of the common problems with the model is the failure of the timing belt. The reasons for this may be different:
- Simple wear and tear caused by a long period of use of the vehicle;
- Regular increased loads under which the engine has to work intensively;
- Mechanical damage as a result of improper operation or received during the repair of other components;
- Manufacturing defect.
Regardless of the causes of the problem, it must be eliminated.
Differences in mechanisms with 8 and 16 valves, operating diagram
Operation on a 16-valve engine is not fundamentally different from that on an 8-valve engine. Its gas distribution system has two camshafts and an additional pulley that holds the timing belt, which is slightly longer in the 16-valve engine. Therefore, when tensioning the belt, you need to monitor the position of not two pulleys, but three. Each of them is marked for this purpose, as in the 8-valve system.
For clarity, you can use the diagram below. Using it, it will be easier to replace the timing belt on a 16-valve engine.

Features of the Priora car
The engine of the new Lada
The engine on the Priora belongs to the class of so-called DOHC engines (Double overhead camshaft), which have two shafts, each for its own row of valves (two for exhaust, two for intake). The valves are driven by pushers, which gives an advantage in power delivery.
The timing belt on a Priora car is a rubber-mechanical product with teeth along the inner edge. Its rim indicates the type of engine for which the part is suitable, as well as markings indicating the number of teeth (137) and width (22 millimeters). When purchasing a timing belt, you should check its quality by pressing on a non-toothed surface. Obvious product defects include the appearance of longitudinal or transverse cracks, delamination, and excessive roughness on the teeth.
The timing belt goes through a tensioner pulley, a timing pulley on the crankshaft, a coolant pump pulley, a pulley (toothed) for the exhaust camshaft, a pulley for the intake camshaft, and an idler pulley. The system also has marks on the crankshaft pulley, oil pump, belt cover (rear), and on both camshafts.
In the factory configuration, the car is equipped with a Gates Kit timing belt with plastic rollers, which are not of good quality, so experienced “prior mechanics” prefer to change this part even before the recommended period expires.

*check prices with an authorized dealer at the time of purchasing parts.
Before purchasing components, check the compatibility of the part with your technical device. Check the article numbers with the data specified in the operating instructions.
When replacing parts, do not forget to place marks on the crankshaft and camshaft. Many car enthusiasts neglect the rule, as a result of which the engine does not start, operates unstably, and the ignition timing shifts.
Which manufacturer is better: domestic or foreign? Russian analogues are not inferior in quality to imported ones. Whether it’s worth overpaying for “delivery” - decide individually, but you need to listen to the opinion of experts.
Causes of timing belt wear on VAZ 2115
- Duration of vehicle operation without intermediate prevention and diagnostics;
- Installation of non-original parts, poor workmanship;
- Mismatch in length, width, number of teeth;
- Aggressive driving style, speed limits;
- High, low temperature conditions, climatic features of the region where the technical product is used.
Manufacturer's recommendations
- Your primary task as a car owner is to periodically visually inspect the unit.
- In addition to replacing the element, it is necessary to simultaneously replace the tension rollers.
- VAZ 2110 comes with 8 and 16 valves. The replacement process also depends on this. So, in an 8-valve valve, one tension roller is installed, and in a 16-valve valve, a support and a tension roller are installed.
Replacing the timing belt of a dozen is not difficult. It is not necessary to contact specialists. It is quite possible to do it on your own.
To complete the job of replacing the timing belt you will need:
- A set of spanners and open-end wrenches;
- Mount;
- Screwdriver Set;
- A special key with which to tighten the roller or simple pliers with curved rings;
- Car jack;
- Rags, protective gloves.
Many people ignore the advice on using gloves. Especially in the summer when it's hot. But they are needed to protect you from injury.
There is no need for an inspection hole. You will need to remove the right wheel to remove the timing belt if your Ten is equipped with power steering. So you can't do without a jack.
