Replacing the timing belt of Lada Granta 8 valves is required once every 75 thousand kilometers. If you ignore the scheduled replacement of the belt, tension roller and sometimes the pump (coolant pump), you may end up with serious repairs to the Lada Granta engine. After all, a broken timing belt almost always leads to damage to valves, valve seats and even pistons. Therefore, the timing drive must be treated very carefully. Every 15 thousand it is necessary to inspect the belt for breaks, cracks, peeling or oiling.
The advice applies to VAZ, 11186 and 21116 engines. All of them are 8-valve and are installed in Grant cars. Let's consider replacement steps.
First, remember a simple rule: the 11183 engine cannot bend its valves, so you can rotate the crankshaft and camshaft pulley separately. For motors 11186 and 21116 this would be unacceptable!

Before carrying out any work, disconnect the battery terminal (key 10), as well as the DPKV sensor. But first you need to remove the protective cover. To remove the protection you need: 11186/21116
- using a “5-point hexagon”, unscrew the 4 bolts on the top part, which is then removed.
And the lower part is also dismantled; 11183
– use a 10mm wrench to unscrew the 3 fastening bolts. It will not be difficult to cope with what is said above.
The crankshaft position sensor (CPS) is disconnected from the connector (see photo). Then the fastening screw is unscrewed with a “10” wrench. The sensor itself must be removed.
Installation of all shafts according to marks
First check that the gear is in neutral.
There is a rubber cover on the crankcase body closer to the clutch assembly. It needs to be removed. The point is to achieve alignment of the marks on the flywheel and in the scale slot. When this is done, fix the flywheel with a screwdriver.
Of course, it is easier to perform such an operation with two people. Know that the desired position of the shaft corresponds to the alignment of marks AB and CD (see figure).
The crankshaft itself must be rotated to the right using a 17 or 19 key (motor 11183).
The meaning of this is illustrated in the photo. The alternator belt must be removed.
The alternator belt blocks access to the timing drive parts. You will have to loosen the fastening and remove this belt.
Use a 13mm wrench to loosen the lower mounting bolt. Then unscrew the upper fastening nut and remove the bolt. The generator casing is pressed against the engine and the structure is secured with wire. The belt can now be removed. Installation of the alternator belt is carried out in the following sequence:
1
.
Secure the generator; 2
.
Throw the belt over the pulleys, as shown in the photo; 3
. Having engaged 5th gear, roll the car back.
Please be aware that reusing the alternator belt is a last resort. It would be better to buy a new part.
Replacing the alternator belt on a Lada Granta 16 valves (Lada Granta with air conditioning)
- Jack up the right side of the car and remove the wheel.
- Unscrew the five screws in the wheel arch and remove the lower part of the “protection”. This is necessary to ensure unobstructed access to the engine mount; it must be removed.
- Unscrew the 8 bolts around the perimeter of the oil pan protection and remove it.
Mounting points for the mudguard and fender liner: 1 — screw with a Torx T-27 key for general fastening of the mudguard and fender liner to the wheel arch; 2 — two Torx T-20 screws for general fastening of the mudguard and fender liner to the wheel arch and fender; 3 - Torx T-20 key screw for fastening the fender liner to the wing; 4 — four self-tapping screws “8” for fastening the fender liner to the wheel arch; 5 - four Torx T-20 screws for fastening the fender liner to the front bumper.
- We install a wooden block in the center of the oil pan and lower the car onto the block.
- We unscrew the engine mount; it is secured with two bolts and one nut (at “17”).
Replacing the timing belt
Make sure the engine flywheel has been correctly installed and secured (see above).
Then, using a “17” or “19” wrench (ICE 11183), unscrew the screw holding the generator drive pulley. The pulley itself and the protective washer are then removed. The pulley should not interfere
Now you need to weaken the downforce in the tension roller: 11186/21116 - using a “15” round key, unscrew the fastening bolt 2-3 turns. The roller will “release” the belt automatically;
The automation will work to loosen
11183
- use a “17” wrench to loosen the fastening nut. Then the roller itself is rotated clockwise. All that remains is to replace it: a new part is installed in place of the old timing belt, and that’s it. Installation of the remaining parts is carried out in the reverse order.
Basic replacement operation
To increase downforce, the outer roller assembly is rotated counterclockwise. For engines 11186/21116, an additional requirement must be met: the two rectangular marks must coincide.
Mandatory requirement for motors 11186/21116
Upon completion of installation, the marks AB and CD should also match. The drawing for them is given above.
Tightening torques
To perform installation correctly, you need a wrench with a force regulator. The value on it is set depending on the type of part: Tension roller mounting screw (11186/21116) – 17-27 N*m; Roller fastening nut (11183) – 30–36 N*m; Generator pulley fastening – 105–110 N*m. First, the tension is adjusted on the roller, and then the fastening nut or bolt is tightened. Parts from the VAZ catalog
Let's immediately look at the list of VAZ components and special tools: Tensioner roller for internal combustion engine 11183 - 2108-1006120, nut for it - 00001-0021647-21; Timing belt (11183) – 2108-1006040-10; Automatic tension roller – 21116-1006226; Timing belt (11186/21116) – 21116-1006040; Key for automatic roller – 67.7812.9573-01; Key for roller VAZ-11183 – 67.7834.9525. The tension roller of the "2108" family has two slots on one side. These slots should look “up”, that is, away from the engine.
The slots were made for special tools. It is designated by the numbers “67.7834.9525” (see list). And for automatic rollers, the key is designated differently - “67.7812.9573”. What it looks like is shown below.
The automatic roller can also be adjusted
It remains to list how the fastening bolts, washers, and so on are designated: Three bolts for the VAZ-11183 cover - 00001-0009024-11, washers - 00001-0026406-01; Timing drive cover (11183) – 21080-1006146-10; Bolts for VAZ-21116 covers – 2108-1003286-00, spring washers – 00001-0011977-73; Top cover – 21116-1006226-00, bottom cover – 21116-1006218-00. We hope no questions arise here. Imported analogues
To replace the “2108-1006040-10” belts, different components are suitable: GATES – 5521 or 5521XS; BOSCH – 1 987 949 095; DAYCO – 94089; CONTITECH – CT527; Finwhale - 2108-1006040. The timing belt “21116-1006040” can be replaced with another part: GATES – 5670XS; CONTITECH – CT1164; QUARTZ (Germany) – QZ-5670XS. Usually the choice is made in favor of GATES products. The letters "XS" in its catalog mean "reinforced".
Attention! Components from GATES (England) are most often counterfeited! From the photo you can understand what the main difference is. Beware of fakes.
Checking the timing belt
According to the documents that come with the car, the belt synchronizing the movement of the shafts has a service life of 45 thousand kilometers. However, it may fail even earlier due to increased load or insufficient attention to the car engine.
A performance check should be performed every 15 thousand kilometers. To do this, you need to remove the cover from the timing belt drive.
- First of all, check the belt tension adjustment tab: the cutout of the inner roller disk should coincide with the tab located on its rectangular plug. Even if the differences are minor, this consumable must be replaced.
- Then inspect the external part of this Lada Grant component. Make sure there are no signs of wear, oil, sludge, threads.
- At the end, the belt must be integral, without any separation into layers and fibers.
The Lada Granta has an eight-valve engine with 87 horsepower installed in the elevator housing. When the timing belt is damaged on this engine, the valves on the pistons are bent, putting you at risk for difficult engine repairs.
When purchasing the component, please note that Grant uses a 113 tooth belt that is 17 millimeters wide. Replacement
a faulty component with the proper selection won't be needed anytime soon, so examine the new part carefully before purchasing.
Automotive enthusiasts recommend purchasing Gates spare parts from the USA. The good thing is that official support can tell you the address of the nearest store where they sell high-quality spare parts. The price of a repair kit (belt and roller) is about 3,000 rubles. At the same time, you will receive a high-quality product, the resource of which is approximately twice as long as that of stock one (about 80 thousand kilometers).
Signs of a Worn Belt
You can avoid expensive repairs by monitoring the condition of the parts in the timing mechanism drive. This will make it possible to timely detect the beginning of the process of destruction of parts in the drive and prevent the creation of a situation where motor repair is required. First of all, pay attention to the condition of the product and its wear. If wear is high, heavy loads or high ambient humidity can cause the belt to slip.
Increased wear can cause deviation towards the tension roller and strong heating due to a failed bearing. Protruding shreds of drive material indicate that wear has begun. The owner should be alarmed by the appearance of cracks; the greater the number of such damages, the shorter the remaining service life of the product. If the outer side of the belt appears shiny, it indicates a loss of elasticity and must be replaced. If the drive has lengthened to such an extent that its tension cannot be adjusted, the belt must be replaced.

How is the replacement made?
So, you have discovered a defect or time for a planned repair. Replacement
carried out step by step only when the engine is cooled:
- Disconnect the battery from your Lada Grant.
- Remove the crankshaft position sensor. Place the sensor in a clean place, such as a shelf, that is free of steel filings or oil.
- With the piston on the first cylinder, place it at top dead center.
- Rotate the crankshaft until the mark on the crankshaft pulley aligns with the protrusion on the drive cover.
- Remove the yoke from the inspection window (located on the coupling body) and check the shaft position. If you did everything correctly, a sign will appear in the field and will be in front of the slot. Stop the flywheel using a screwdriver (it must be installed between its teeth).
- Unscrew the generator drive pulley, remove it from the shaft and remove the washer.
- Remove the camshaft cover.
- Loosen the tension roller (it should turn).
- Remove the belt from all pulleys and pull out.
- If you need, in addition to installing the timing belt, remove the tension roller and replace it with a new one, unscrew the mounting bolt, and then remove the roller directly from it.
- Before submitting a new video, check to see if a replacement
. To do this, take the metal middle of this mechanism and rotate the plastic part. When the accessory is working, it moves smoothly without jamming. - Inspect the pump and begin reinstalling the gas distribution mechanism. Place the roller in the top hole on the cylinder block, but do not turn the bolt that secures this part of the drive all the way.
- Install the belt so that it operates correctly on all pulleys and rollers. To install the belt correctly, after laying it on the crankshaft pulley (it must be installed in its place), pull both parts of the part. Try to distribute the load evenly.
- The farthest part belt
should lie on the pump pulley and go behind the tension roller (check the chain at this stage), and the closer it should lie neatly on the camshaft gear. - Pull the camshaft slightly (in the direction of the lower stroke) until the teeth on the belt
align with the notches on it. Use a special wrench to turn the tension roller counterclockwise.
After the replacement
, check the tension of the timing belt. Excessive voltage in it on Grant Lade is fraught with failure of the cooling system pump. In addition, if the belt is over-tensioned, it can quickly trip.
A loose belt can lead to poor valve timing. Turn the crankshaft to the right until the alignment marks line up. After this, turn over the alternator pulley assembly. Remember that when removing the belt
It is strictly forbidden to turn the shafts on a Lada Grant model car.
The adjustment is only made when the replacement
has already been completed.

Lada Granta 8 valve: how to replace the timing belt yourself
Owners of domestic cars most often prefer to carry out repairs themselves. This is due to the fact that the components for them are sold in almost any auto parts store and are inexpensive. In addition, the Lada Granta device resembles earlier models released from the AvtoVAZ assembly line. Replacing almost any component on this car will not cause you any inconvenience.
Assembly, testing
The drive assembly is performed in the reverse order, but with certain nuances observed. First, we put the tension roller in place and tighten the bolt securing it, but do not tighten it.
In a 16-valve engine, before putting on the belt, we put both rollers in place, but unlike the tensioner, the bypass roller can be tightened immediately.
The belt is worn from bottom to top. That is, first the belt teeth are installed on the crankshaft toothed pulley, then it is put on the pump, then wound by the rollers, and only then put on the camshaft pulley.
After installing the belt, tension it. To do this, a special wrench or pliers are installed in special holes in the outer race of the tension roller, after which it is turned clockwise until the cutout on this race aligns with the rectangular notch on the inner sleeve.
Holding the roller in this position, tighten the bolt securing it.
Having finished tightening, we install the lower protective cover, washer and generator drive pulley in place. After this, we check that the work was completed correctly.
To do this, first check that all the marks match, then turn the crankshaft several turns, after which we align all the marks again. If they converge, the replacement work has been completed correctly and you can continue assembly. Here we note that a slight deviation on any marks is allowed, but not more than a couple of millimeters.
When checking the alignment of the marks on a 16-valve engine, more attention must be paid to this action, since there are two camshafts, and a mismatch of marks on any of them can lead to significant interruptions in the operation of the engine.
And only after such a check, everything is assembled further - the generator drive, the upper protective cover, and the wiring of the crankshaft position sensor are installed.
Checking the timing belt
According to the documents that come with the car, the belt synchronizing the movement of the shafts has a service life of 45 thousand kilometers. However, it may fail earlier due to increased loads or insufficient attention to the car engine.
A performance check must be carried out every 15 thousand kilometers. To do this, you will need to remove the cover from the timing belt drive.
- First of all, check the belt tension control tab: the cutout of the inner roller disk should coincide with the tab located on its rectangular bushing. Even with minor discrepancies, it is necessary to replace this consumable.
- Next, inspect the outside of this Lada Granta component. Make sure there are no signs of wear, oil, carbon deposits, or threads.
- At the end, the belt must be integral, without separation into layers and fibers.
The Lada Granta in the liftback body has an eight-valve engine with a power of 87 horsepower. If the timing belt breaks on such an engine, the valves bend on the pistons, which threatens you with difficult engine repairs.
When purchasing a component, please note that the Grant uses a belt with 113 teeth, the width of which is 17 millimeters. If you choose the right one, you will not need to replace a failed component soon, so carefully study the new part before purchasing.
Car enthusiasts recommend purchasing Gates brand components from the USA. The good thing about this is that official support can tell you the address of the nearest store that sells quality spare parts. The price of a repair kit (belt and roller) is about 3,000 rubles. At the same time, you will receive a high-quality product, the service life of which is approximately twice that of stock (about 80 thousand kilometers).

About Lada Granta engines
To complete this model, manufacturers produce five modifications of gasoline power units. All of them have an injection power system, the working volume of these engines is 1600 cm3. Two modifications have 8 valves in the cylinder head, the rest have 4 valves per cylinder, that is, there are a total of 16 valves in the head. The timing mechanism of all motors is driven by a toothed belt.
Let's take a closer look at the 8 valve modifications of the Lada Granta power units.
- The motor with index 11183-50 has been installed on the machine since the beginning of its production. The VAZ 2111 with minor modifications is taken as the basis. The power of this engine is 82 hp. With. Emissions of exhaust gases into the atmosphere have changed significantly for the better. The engine shows better dynamics and efficiency. The pistons have recesses, so a belt break does not cause damage to the valve mechanism. It is somewhat noisy in operation and requires periodic adjustment of the clearances in the valve mechanism.
- Further modernization of the VAZ 2114 engine received the index 11186. Its power became equal to 87 horses. The connecting rod and piston group of the power unit was subject to changes, the weight of which was reduced by approximately 30%. This not only improved the environmental performance of the engine, but also reduced noise during operation and fuel consumption, but the engine life was slightly reduced. Due to the reduction in piston height, there are no recesses in its head, so a toothed belt break will always be accompanied by damage to the valves.
16 valve Lada Granta engines:
- The VAZ 21126 is a modified engine of the VAZ 21124, which experts consider the best engine of all that are equipped with Grants. The power of the power unit increased to 96 horses. This was achieved by increasing the number of valves per cylinder, which improved the filling of the cylinders with the working mixture and the rapid removal of exhaust gases. The pistons do not have recesses, so bending when the belt breaks will be inevitable.
- The modification of the 21126 engine received the VAZ 21127 index, the power of which became equal to 106 horsepower. The engine began to pull better at low speeds. The problem of valves bending when the valves are damaged remains.
- VAZ 21126-77 is an engine for the Lada Granta Sport, the power of which is 120 hp. With. Apart from the increased power rating, it is no different from the 21126 model. A break in the timing mechanism drive is always accompanied by damage to the valve mechanism.
How is the replacement made?
So, you have discovered a defect or the scheduled repair is due. Replacement is carried out step by step only with a cooled motor:
- Disconnect the battery of your Lada Grant.
- Remove the crankshaft position sensor. Place the sensor in a clean place, such as a shelf, that is free of steel filings or oil.
- Place the piston of the first cylinder at top dead center.
- Rotate the crankshaft until the mark on the pulley aligns with the protrusion on the drive cover.
- Remove the plug from the inspection window (located on the clutch housing) and check the position of the shaft. If you did everything correctly, a mark will appear in the window and will be located opposite the slot. Lock the flywheel using a screwdriver (it must be placed between its teeth).
- Unscrew the generator drive pulley, remove it from the axle and remove the washer.
- Remove the timing cover.
- Loosen the tension roller (it should turn).
- Remove the belt from all pulleys and pull out.
- If you need, in addition to installing the timing belt, to remove the tension roller and replace it with a new one, then unscrew the fastening bolt and then remove the roller right along with it.
- Before installing a new roller, check whether a replacement is really needed. To do this, grab the metal middle of this mechanism and turn the plastic part. With a working component, it moves smoothly, without jamming.
- Inspect the pump and begin reassembling the gas distribution mechanism. Install the roller into the top hole on the cylinder block, but do not fully tighten the bolt securing this part of the drive.
- Place the belt so that it runs correctly over all pulleys and rollers. In order for the belt to fit correctly, after laying it on the crankshaft pulley (it must first be installed in its place), tighten both parts of the part. Try to distribute the load evenly.
- The far part of the timing belt should lie on the pump pulley and go behind the tension roller (at this stage, check the diagram), and the near one should carefully lie on the toothed part of the camshaft.
- Turn the camshaft pulley slightly (in the direction of the smaller stroke) so that the belt teeth align with the notches on it. Use a special wrench to turn the tension roller counterclockwise.
After the replacement has been made, check the timing belt tension. Excessive voltage in it on the Lada Granta is fraught with failure of the cooling system pump. Also, if there is excessive tension, the belt can fail very quickly.
A loose belt can lead to poor valve timing. Turn the crankshaft to the right so that the timing marks align. After this, reassemble the generator pulley. Remember that when the belt is removed on a Lada Grant model, turning the shafts is strictly prohibited. The setting is done only when the replacement has already been carried out.
There is a special offer on our website. You can get a free consultation with our corporate lawyer by simply submitting your question in the form below.
Before you start replacing the belt, you should actually purchase it. To find any spare part you need near you, go to https://autokontact.com/, and the service will immediately give you the nearest stores. Then, we proceed to the replacement.
To replace a timing belt with an automatic tensioner, use a 5 mm wrench. Unscrew the 4 bolts on the front top cover and remove it.
We place the car on a reliable stand by removing the right front wheel.
Remove the right side of the engine splash guard and then the generator drive belt.
We begin to rotate the crankshaft until the marks on the camshaft pulley and the rear belt cover align with a 17 mm socket wrench. The position where these marks coincide corresponds to the location of the piston of the first cylinder in the extreme upper position, which is called top dead center (TDC). Attention! Do not turn the crankshaft by the pulley bolt! The crankshaft can be held by the flywheel ring gear with a slotted screwdriver while removing the rubber plug located on top of the clutch housing. Also, the crankshaft pulley bolt can be unscrewed if an assistant shifts into high gear and presses the brake pedal. However, the crankshaft may turn slightly. Therefore, it is necessary to re-check that all marks match.
Then you need to unscrew the bolt securing the pulley and remove it.
Take a 5mm hex key and unscrew the 3 bolts that secure the lower belt cover and remove it.
Remove the limit washer from the crankshaft.
Now take the 15mm wrench and slightly loosen the belt tension by turning the automatic tensioner mounting bolt half a turn counterclockwise.
We remove the timing belt and check the condition of the tension roller by rotating it. If it makes a lot of noise or there is visible play, it must also be replaced.
Now we put on the new belt. We make sure that the mark of the crankshaft toothed pulley fits with the boss made on the oil pump housing.
We put the belt on the camshaft pulley so that the front branch is tensioned. Without letting the belt loosen, we put it on the pump pulley and on the tensioner pulley.
A broken timing belt and its subsequent replacement is a fairly common problem among owners of a Grant car, both with an 8-valve engine and with an engine with 16 valves installed.
Very often among car enthusiasts you can hear a conversation that, due to a torn belt, the engine seized or the valves were “bent”. Why this happens and how to prevent such a phenomenon, as well as how to change the part yourself, will be discussed in our article.
Which kit to buy
In addition to the toothed belt, a tension roller and a coolant pump are purchased. The main supplier of rubber products is the RTI plant in Balakovo. Products from GATES, BOSCH, DAYCO, CONTITECH have proven themselves well. If the pump in the engine cooling system is replaced, antifreeze will be needed to top it up.
Yesterday one of our regular customers came to us with a recently purchased second-generation Kalina to replace the timing belt, roller and pump, plus all the fluids, but more on that in another article. This engine was also installed on the Grant, so this article will be relevant for it as well. The speedometer shows 60,000 and I believe that for this engine this is the optimal replacement interval, even though all reference books say about 75,000.
Let’s make a reservation right away that when the timing belt breaks on this car, the valves bend. It is recommended to check the condition of the belt every 15,000 kilometers.
To work, we will need a set of keys and sockets, as well as a 5-point hex and a key for the tension roller. The entire procedure takes approximately one and a half hours.
The engine is similar to the eighth.
First, remove the protection, drain the antifreeze, and for convenience you can remove the right front wheel. Next, loosen the locknut of the generator belt tensioning mechanism. Using a 10mm socket, unscrew the tensioner pin and remove the belt.
We unscrew the four bolts with a 5mm hexagon and remove the upper protective cover of the timing belt.
Set top dead center (TDC). We turn the crankshaft by the pulley mounting bolt clockwise until the mark on the camshaft sprocket and the timing belt protective casing coincide.
Unscrew the crankshaft pulley bolt. We block the wheels with stops, tighten the handbrake, engage fifth gear and, with a slight movement of the wrench and a one and a half meter pipe extension, unscrew this bolt.
Remove the protective washer.
The marks on the crankshaft sprockets should be aligned with the oil pump casting.
Praise be to the designers of AvtoVAZ, finally rollers with a tension indicator appeared on the engines, now you don’t need to tighten them by eye and check the tension by twisting the belt, not even thirty years have passed since the invention of such a design. We unscrew the tension roller bolt and dismantle the latter; we also remove the old timing belt. The photo shows that the belt has stretched out because the tension marks have diverged; when checking the condition of the timing belt, if you see this, you will just need to tighten it.
To replace the pump, we need to remove the camshaft sprocket, and also unscrew several bolts of the inner casing and remove it.
Three bolts out and the pump replaced. The green arrow indicates the hole for the tension roller bolt.
Having replaced the water pump, we proceed to install a new timing belt.
We put the casing and camshaft sprocket in place. We check that all the marks match, as discussed above. We install the tension roller, but do not tighten the bolt. We put on a new belt, observing the direction of rotation, first on the crankshaft sprocket, camshaft, tension roller and pump, the latter can be swapped. We tighten the timing belt. Use a special key to turn the roller counterclockwise, as indicated on its body...
...until the marks on it coincide and tighten the bolt.
We turn the crankshaft two turns and again check the alignment of the marks and the belt tension.
We install all the parts in the reverse order of removal, fill in antifreeze and start it. It couldn't be simpler. Good luck on the roads. No nail, no rod!
Replacing the timing belt of Lada Granta 8 valves is required once every 75 thousand kilometers. If you ignore the scheduled replacement of the belt, tension roller and sometimes the pump (coolant pump), you may end up with serious repairs to the Lada Granta engine. After all, a broken timing belt almost always leads to damage to valves, valve seats and even pistons. Therefore, the timing drive must be treated very carefully. Every 15 thousand it is necessary to inspect the belt for breaks, cracks, peeling or oiling.
The advice applies to VAZ, 11186 and 21116 engines. All of them are 8-valve and are installed in Grant cars. Let's consider replacement steps.
First, remember a simple rule: the 11183 engine cannot bend its valves, so you can rotate the crankshaft and camshaft pulley separately. For motors 11186 and 21116 this would be unacceptable!
Timing belt. What is it for?
To transmit torque from the crankshaft to the timing system, most modern cars use a drive belt. Car mechanics and drivers call this part a timing belt. This product is made of durable rubber, reinforced with a special fiberglass cord. For better traction, it has teeth that match the size of the notches on the crankshaft and camshaft pulleys.
The belt performs an extremely important function in the operation of the engine, ensuring a smooth cycle of the intake and exhaust mechanism, and removing exhaust gases to the outside. In addition to the engine shafts, the timing belt on the Grant 8 valve also drives the coolant pump, which is called the “pump”. Without a reliable drive, the operation of the power unit is impossible in principle, so each driver needs to carefully monitor the integrity of the part and replace this element within the prescribed time frame.
Factory regulations for timing of timing belt replacement
Each vehicle manufacturer specifies the timing of maintenance and other routine maintenance. According to this document, replacing the timing belt on a Lada Granta car should be done when the car has driven no more than 75 thousand km . In fact, this figure does not always correspond to reality; there are a number of reasons for this. The service life of a timing belt will depend on:
- The quality of the product used.
- Vehicle operating conditions.
- Technical condition of the engine.
- "Age" of the timing belt.
Much attention is paid to the manufacturing quality of rubber products, but the quality of parts from different manufacturers varies greatly. The main supplier for VAZ is the RTI plant, which is located in Balakovo. In addition to it, engines can be equipped with products from other companies such as Gates, ContiTech, Trialli, Bosch, and some others. You should carefully consider the product you are purchasing, since you can buy a fake under the guise of products from well-known manufacturers.
The operating conditions of the vehicle, especially its engine, also affect the service life of the timing drive. In 16 valve modifications, the load on the belt teeth increases, so it requires more attention. Fuel and technical fluids are not allowed to enter the operating area of the timing mechanism drive. They soften the body of rubber products, make the material pliable, and the teeth are easily cut off. At the slightest manifestation of leaks in the operating area of the timing drive, they must be eliminated immediately.
The teeth of the crankshaft gears and camshafts gradually wear out, and the height of the teeth decreases. This means that the contact area with the belt becomes smaller, making it easier to tear off the toothed belt comb. The coolant pump can also become a source of trouble for the timing drive. Sometimes it jams, and since the pump is rotated by a toothed belt, its teeth are cut off.
Timing belt replacement period on Grant
The manufacturer of Lada cars, the AvtoVAZ concern, stipulates the timing for replacing the Granta belt - 75 thousand km. The established term applies to all Grant cars, regardless of the number of valves.
In addition to scheduled replacement, a prudent driver always monitors the condition of the drive, since it may break prematurely due to its poor quality or improper installation. Therefore, the decision “how long does it take to change the timing belt on a Grant?” Each driver decides independently.
How long does it take to replace it?
The factory operating instructions for the vehicle recommend replacing the timing belt after a mileage of 75 thousand km. This standard is not always followed by owners, and there are good reasons for this. How long the drive lasts before replacement depends on many factors. This is the quality of the parts used, the operating conditions of the vehicle, and the technical condition of the engine. During each maintenance, the tension and condition of the timing drive should be checked. If cracks, peeling, or other damage appears, the belt should be replaced.
With a high mileage of the car, natural wear of the crankshaft and camshaft pulleys occurs, this significantly reduces the service life of the entire timing drive. The drive is also afraid of engine oil getting into the belt operating area. It softens its structure, the teeth are easily cut off. If the car has been sitting idle for a long time, it is also better to replace the drive due to its aging. Most owners and experts recommend changing the belt after a mileage of 50 thousand km.
Why does a belt suddenly break?
In some cases, even a new part can suddenly break, causing a lot of inconvenience to the owner of the vehicle. Most often, the teeth are worn out due to the fact that the Grant timing belt was installed incorrectly. In this case, it runs crookedly on the pulleys and rollers and its teeth “eat” the metal elements of the pulleys.
Other causes of premature wear may include:
- Poor part quality. In this case, savings can play a cruel joke on the driver, so you need to make a purchase in trusted stores
- Pump malfunction. This is one of the most common causes of breakdown. The pump rollers break over time, forming a gap and displacing the axis. As a result, its teeth quickly wear out and lead to breakage.
- Tension roller malfunction. The same thing can happen with a roller as with a butt. A bearing failure creates play and displaces the tension axis.
- Oil or antifreeze leak. When technical fluids get on the belt, they destroy the rubber from which it is made and greatly affect the strength of the part.
- Wear of pulley teeth. If the camshaft or crankshaft gears are severely damaged, integrity will be immediately affected. In this case, the teeth will have delamination on their surface.
In addition to all of the above, the fact that the timing belt on the Lada Granta 8 suddenly breaks can be caused by a trivial reason for its untimely replacement.
If the frequency of replacing the Lada Granta timing belt is not correct, then the driver should count not only on purchasing a new one, but also possibly on a complete engine repair. The cause of the rupture can be diagnosed according to the following scheme:
Replacement frequency
The manufacturer's technical documentation states that the timing belt on the Lada Granta must be replaced every 60 thousand kilometers.
But here it is worth noting that this is a limit value and it is better to replace it before reaching such a mileage, approximately 50 thousand km, but there are cases when the drive requires replacement at 40, or even 30 thousand km, it all depends on the quality of the belt and its working conditions.
In any case, it is better to periodically check the condition of the drive (recommended every 15 thousand km) and if signs of wear are detected, replace it immediately.
If this is not done, then it may break, which is fraught with serious consequences - the engine pistons will collide with open valves, leading to their damage and subsequent expensive repairs.
Consequences of a broken toothed belt. Is everything really that scary?
The manufacturer installs several types of power units on Grant cars.
There are 5 of them in total:
- VAZ-11183-50
- VAZ-11186
- VAZ-21126
- VAZ-21127
- VAZ 21126-77
The first two are eight valve, and the rest are 16. Sad consequences in the form of damaged valves due to a broken timing belt on Grant threaten all of these engines, with the exception of the VAZ-11183-50.
It goes like this. When the timing belt breaks on a Grant car at high speeds, this leads to the connection between the engine shafts being lost. The camshaft stops abruptly, but the crankshaft continues to move as the engine is running. As a result, the piston hits the stationary valves sharply, which can bend and even break. Such damage threatens with expensive repairs of the entire gas distribution system, and if the piston is also damaged during the impact, then replacement of the piston group, which is even more expensive.

How to determine that a break may soon occur
Urgent replacement of the timing belt for a Granta car of 8 and 16 cl. may be necessary if the following phenomena occur:
- Decrease in vehicle power. A poorly tensioned or worn drive can make the engine difficult to start and reduce power output.
- Incomprehensible noises from the timing belt on the Grant, emanating from the engine compartment. Clunking, ticking or strange rustling noises often indicate that the Granta timing belt is damaged and rubbing against the casing or other parts under the hood
- Visible damage. The part may have abrasions, cracks and “shaggy” areas that are visible to the naked eye.
If, upon careful inspection, it is discovered that the teeth on the Grant timing belt have been cut off or at least one of the other listed problems, it is necessary to urgently replace the part with a new one, which is quite possible to do yourself.

Replacing the belt on an 8-valve Lada Granta engine. Detailed description
After making sure that the part is in poor condition, you need to prepare for the procedure of replacing the timing belt on a Lada Granta 8 valve. First of all, you need to provide a comfortable place to work, well lit, spacious enough and safe.
Tools you will need:
- Wrenches included in the set
- Heads with extension
- Mount
- Special device for adjusting the roller
The tensioner pulley is often replaced at the same time, so it is necessary to purchase it in advance. In all stores you can buy a timing belt pulley for Granta as a set.
Before starting work, you must unscrew the ground wire from the battery.
Let's consider the process of replacing the timing belt on a Lada Granta car using the example of an 8-valve engine. Main stages of work:
Preparing for repairs.
The car is jacked up and the front wheel is removed from the right side, as well as the protection that blocks access to the engine.
Removing the protective cover.
On Grant cars, the plastic cover consists of two parts. It's easy to remove. First you need to unscrew the 4 bolts of the upper part, and then the lower part.
To do this, you need to use a 5-point hex key. In addition to the cover, you also need to remove the crankshaft position sensor by simply disconnecting it from the connector and removing it from the socket.
Alignment of marks.
Before replacing the timing belt on Granta 16 and 8 valves, it is necessary to correctly set the engine valve timing. To do this, you need to turn the crankshaft clockwise. This is done using a 17-inch socket. You need to turn it until the mark on the camshaft toothed pulley coincides with the mark on the inner surface of the timing cover.
In addition, the marks must line up on the engine flywheel. This can be checked through a special hatch in the upper part of the clutch housing. After removing the rubber plug, you need to make sure that the special protrusion on the flywheel coincides with the camshaft mark.
Only after this can you continue replacing the timing belt on the Lada Granta.
Removing the generator pulley.
To prevent the shafts aligned to the marks from turning, the flywheel can be locked through the inspection hatch. The most convenient way to do this is with a thick screwdriver or pry bar. Having firmly secured the flywheel, carefully unscrew the nut holding the generator pulley and remove it along with the washer.
Next, loosen the generator pulley nut
Adjusting the tension roller.
Using a 15mm wrench, you need to gradually loosen the tightening of the roller mounting bolt. When the fastening is loosened enough to allow sagging, you can begin dismantling, making sure once again that all the marks match.
Withdrawal. The part is carefully removed from all pulleys and removed from the engine compartment. If there is a complete break in the timing belt on Grant's car, this is even easier to do.
Helpful advice: while you are changing the timing belt on the Grant, the protective cover is removed and you can check the condition of the water pump and tensioner pulley. The video is removed and played in the hands. If there is no extraneous noise and the bearing does not jam, it is installed back. The water pump is checked by twisting it by the pulley. If nothing sticks, she's fine.
Installation of a new spare part. Before use, the timing belt on Grant 8 valves is checked for manufacturing defects - peeling, cracks, excessive roughness of the material. It would be useful to look at the expiration date, since rubber loses its properties even without being used, but after lying on the shelf for several years. The number of teeth on the Lada Granta belt with an 8-valve engine is 113, and its width is 17 mm. Installation of the part is carried out in the reverse order. First, it is pulled onto the crankshaft, then onto the generator and pump, circling the roller, and at the very end - onto the camshaft. Tension.
To ensure good tension, you need to rotate the roller counterclockwise. This is done using a special key, which consists of 2 metal rods. These are inserted into the corresponding holes on the roller and the roller is rotated until the cutout on the roller cage aligns with the rectangular mark on the inner sleeve. Only after this can the roller bolt be tightened.
In order to understand the sequence of work, we present to your attention an explanatory video about where to look for tags:
We change the belt ourselves
Replacing the timing belt after a specified period on 16 and 8 cl Lada Granta engines is a simple process and even a novice car enthusiast can do it with his own hands. The main thing is to carefully follow all the instructions and not miss anything.
Required Tools
- keys for 10 and 17;
- mounting spatula;
- roller tension wrench;
- jack;
- set of TORX (sprockets) and heads;
- forceps.
Roller tensioner
Stages of work
- First, remove the negative terminal of the battery.
- Remove the generator belt drive.
- We fix the car using stops; decide for yourself which ones are best suited for this.
- When we lift the car with a jack, remove the right front wheel.
- Remove the gas distribution mechanism cover.
- The piston of the 1st cylinder should be set at the highest point.
- We loosen the belt tension using a tension roller or bolt.
- Loosen the tension roller nut.
Tension rollers
- Unscrew the bolt securing the generator pulley. If difficulties arise, you need to open the plug in the crankcase. Using a mounting spatula, it is necessary to fix the flywheel teeth; this will keep the crankshaft from turning arbitrarily.
- Remove the generator drive pulley.
- Remove the bottom cover by first unscrewing the three bolts.
- We remove the timing belt drive from the camshaft and crankshaft pulley.
- If necessary, remove the timing belt tension roller.
- We carefully examine it, and if we find that its condition is unsatisfactory, we change it.
- We also inspect and, if necessary, replace the belt.
- Assembly of all other components proceeds in the reverse order.
The next important stage is the correct tension of the timing belt drive of the Lada Granta with 16 cl and 8 cl units.
- First of all, you need to warm up the engine, the coolant temperature should be 20-25° - this is a certain norm. This temperature must be exactly so that the roller marks coincide. If you warm it up to 80-90°, the mark will shift by 5-6 millimeters. Important! Use rollers that are recommended for a Lada Granta 8 or 16 cl, otherwise the results may be different, even the belt may break.
- Next, you need to align the marks of the camshaft pulley and the marks located on the rear cover.
- We fix the pulleys with the device described earlier.
Fixing pulleys
- We align the marks on the crankshaft pulley and on the oil pump cover.
- We turn the crankshaft with a wrench in the shortest angular direction.
- We tighten the bolt securing the auto tensioner.
- We put the belt drive on the support roller, pulleys and auto-tensioner.
- We install a special key for tensioning the belt in the grooves of the auto-tensioner support plate.
Belt tensioner
- Turn it counterclockwise until the first and second marks coincide.
- Tighten the bolt securing the tensioner. The tightening torque should be approximately 2.4/3.5 kgf. m.
- Remove the crankshaft lock and turn it a couple of turns.
- If the first and second marks do not match, you will have to re-tension.
Attention! The tension roller should not move or deviate, no matter how much in one direction or another, this will be proof that it is in good condition and working correctly. This means that its breakage is excluded.
Replacing the timing belt on a 16-valve engine. Process Features
The process of replacing the timing belt on a 16-valve Grant is not much different from the similar process on an 8-valve one. But there are some differences, which are that the 2 camshafts have different marks and they are set slightly differently.
In addition, replacing the timing belt Grants 16 valves automatic is complicated by the fact that to carry out this work it is necessary to remove the starter, which blocks access to the flywheel. The timing belt size of the Lada Granta with a 16-valve engine is 137 teeth with a width of 22 mm. Removing the starter on the Lada Granta Removing the starter is not difficult. To do this, just do the following:
- Disconnect the plastic connectors from the starter
- Unscrew the nut that holds the power terminal. To do this, use a key of 13
- Using the same wrench, unscrew the 3 bolts that secure the starter to the bracket.
- Hold the starter housing and carefully remove it.
After removing this element, you can begin replacing the timing belt. How to set marks on a Grant with a 16-valve engine Since a 16-valve car has 2 camshafts, the marks on each of them must coincide with the recesses on the top of the timing cover, as well as with the engine flywheel. By turning the crankshaft to the right until these marks coincide, the camshafts need to be fixed. A small piece of soft wood or an elastic piece of rubber is perfect for this purpose.
After the marks match, the flywheel is fixed in the same way as on 8-valve models.
Support roller
In an engine with two camshafts, in addition to the Grant timing belt tensioner, there is also a support roller. It performs the function of additional stabilization of the belt, adjusting its correct position in relation to other parts and better functioning of the entire belt drive. Like the tension roller, it must be checked for defects and, if necessary, replaced with a new one.
How to tighten the timing belt on a Grant with 16 valves? The process is not particularly different from replacing the belt on a Lada Granta with an 8-valve one. You need to start with the lower pulley (crankshaft). Then trace the generator and pump pulleys, correctly positioning the part along the rollers, and then put it on the camshaft pulleys.
How to check it yourself
There is an easy way to diagnose a water pump. There is no need to remove the product from the engine. To check the pump on the vast majority of car models, you must:
- Start the engine, warm it up to normal operating temperature (usually this indicator varies from 87 to 100 degrees).
- After this, pinch the upper pipe that comes from the radiator with a gloved hand. If the pump is working properly, you will immediately feel the antifreeze pressure inside the pipe. If the pipe is pressed without difficulty, there is no circulation in the cooling system, that is, the pump does not work.
You can check the functionality of the pump in a minute, especially if under the hood is clean and there are no liquid leaks
How to choose a quality spare part
The Lada Granta timing belt plays a primary role in engine operation, so you need to choose it carefully. During movement, this part can withstand enormous loads, and it must be of the highest quality. Today, there are several proven manufacturers whose products deserve high marks. The most famous and good timing belts for Granta brands: Contitech Gates Dayco Bosch Among domestic manufacturers, one can highlight the BalakovoRezinotekhnika (BRT) company, which provides Granta timing belt life and an affordable price.
For ease of selection for a 16-valve Grant, you can use the following table:
When purchasing products from a well-known company, every driver thinks about which timing belt is best for Grant. But besides this, the car owner must be careful not to fall for a fake. It is necessary to check the presence of holograms and other identification marks used by a particular company, as well as the coincidence of the original part number and the inscription on the box.
You should buy spare parts only from trusted retail outlets, which bear full responsibility for the quality of the products sold.
