The Lada Granta liftback is equipped by default with one of four types of engines with a gasoline power system:
- 82 hp / 8th grade
- 87 hp / 8th grade
- 98 hp / 16 grades
- 106 hp/16 cl.
On the Grant with a 16-valve mechanism, two camshafts are pre-installed, and an additional roller is a tensioner. In the 8-valve design, the listed mechanisms are included in a single configuration.
At the stage of selecting a timing belt, many inexperienced motorists make one significant mistake - the catalog part number does not correspond to the actual one. As a result, the belt is either shorter or longer than the required size.
Purpose of the timing belt
Ensuring synchronized operation of the power unit mechanisms for cyclic supply of the fuel mixture into the combustion chamber with subsequent ignition.
Violation of the tact, operation, and cyclicity leads to instability in the supply of a lean / rich mixture. As a result, the engine does not operate at full power, and detonation can be seen at idle.
The previous article () discussed in detail the purpose of the timing system. For additional information, use the provided link.
Timing belt replacement interval
The manufacturer indicates an interval of 60,000 km, after which the Granta liftback timing belt needs to be replaced. At the same time, every 15,000 km, it is necessary to carry out diagnostics of the drive belt in order to detect defects, delamination, and possible damage.
If the car is operated in rough, dusty terrain, under systematic loads, reduce the replacement interval by a third. Obviously, this is just a recommendation and not a commitment. In order to increase the service life, it is still better to listen to the advice of professionals.
In what cases does a belt break?
- Exceeding the permissible replacement interval without carrying out intermediate prevention;
- Systematic operation of the power unit under loads for which it is not designed;
- Defects in the manufacture of a part or component;
- Frequent contact with the surface of oil, chemical reagents, compounds that cause a reaction, delamination of rubber;
- Drive tension exceeds the permissible norm;
- Insufficient drive tension;
- Tooth wear, deformation, damage.
The duration of the engine operation after time “H” is also an important factor. The faster the driver turns off the ignition, the less disastrous the consequences and vice versa. Service station mechanics know of cases where the rocker arm and valve bases literally pierced the wall of the cylinder block and came out.
Harbingers of an imminent timing belt break
Peeling of rubber, visible thread - cord;
- The drive constantly sags, insufficient tension, despite systematic tightening;
- Multiple white spots are visible on the body, as signals of motor oil getting on the surface;
- Starting the power unit is accompanied by a characteristic squeaking and squeaking sound.
Diagnostics and replacement of the timing belt on an 8-valve engine
Before replacing it yourself, do not forget to carry out comprehensive diagnostics in order to study the general technical condition of the car, identify breakdowns and other malfunctions. To analyze mechanisms without preliminary diagnostics is the height of unprofessionalism.
Diagnostic stages:
- We jack up the right side of the car and hang it at a sufficient height so that the wheel rotates freely by hand;
- We activate fifth gear;
- In the engine compartment, remove the plastic casing and turn the drive belt. We assess its condition and decide whether replacement is necessary.
After the final decision on replacement has been made, we begin dismantling. We first prepare a set of automotive tools, rags, a new belt, and a roller bearing. Bearing replacement is required. The service life is approximately equal to that of the drive belt.
Replacing the timing belt Lada Granta liftback 8 valves
- We place the car within the perimeter of the repair area, squeeze the handbrake, open the hood, and the gearshift lever in the “neutral” position;
- We reset both terminals from the battery to avoid a short circuit in the network;
- Remove the decorative plastic panel in the timing belt area;
- Using a flat-tip screwdriver, make marks on the outer perimeter of the gear and the cylinder body (block);
- By rotating the crankshaft pulley, we align the actual mark with the dead center;
- We tear off the crankshaft pulley mounting nut;
- Unscrew the tensioner pulley mount, reduce the belt tension, unscrew the generator mount, remove the belt from its seat on the pulley;
- We carry out troubleshooting and assess the condition of the teeth. If there is no deformation, replace it with a new belt. We will also inspect the cooling system pump; its operation should be quiet, without noise or wedge. The presence of the opposite indicates a malfunction and the need for prevention;
- Upon completion, we assemble the structure in the reverse order with the obligatory installation of new components.
To make sure that the process was completed successfully, turn the crankshaft pulley 1 - 2 turns. The rotation should be relatively easy. We check the matches of the marks. A deviation of 1 - 2 mm is allowed, no more.
Self-replacement of the timing belt Lada Granta liftback is over.
Features of replacing a drive with a 16-valve engine
A distinctive feature is two camshafts, two pulleys, two tensioner rollers. Obviously, there will also be two marks on the gears and the housing. Two rollers must be replaced.
Where and how to choose quality spare parts
A wide range of products, lack of awareness of owners, fraud by sellers - this is not a complete list of factors that can mislead an inexperienced owner.
To minimize possible risks and prevent the purchase of low-quality goods, we strongly recommend using the services of trusted suppliers, official representative offices, and dealers. To a lesser extent, buy components from unverified sellers, parts at unreasonably low prices.
Make it a rule to check catalog numbers and search indexes for spare parts with the actual data specified in the operating instructions for your car.
The popular VAZ 21116 (11186) engine is also installed on the Lada Granta. This engine doesn’t have enough stars in the sky, but it’s nice because you can easily carry out its maintenance and repairs with your own hands in a garage. He has several problems, however, they can be solved with careful and timely care. Replacing the timing belt on an 8-valve Granta with your own hands will not cause any problems if you change the belt according to technology, not forgetting about choosing a high-quality belt.
There are quite a few tales about what will happen if the timing belt breaks while the engine is running. Unfortunately, regarding the VAZ 21116 engine, most of them are not far from the truth. For this engine, a broken camshaft drive belt is more than critical. The meeting between pistons and valves, as a rule, does not end very well: bent valves, torn connecting rods, punctured cylinder blocks and torn pistons - all this can really happen if the timing belt is not replaced on time.
Bent valves in the block head
For the engine to serve for a long time and reliably, it is simply enough Once every 10-15 thousand mileage, inspect the drive belt camshaft and if alarming symptoms are detected, do not be lazy and change it immediately. Signs that the strap is asking to be retired are clear even to a teapot:
- Cracks, cuts, nicks, and other mechanical damage are clearly visible on the surface of the belt.
- The teeth may be damaged or even cut off.
- The belt has traces of contact with operating fluids - oils, gasoline, antifreeze, brake fluid. But before changing the belt, you need to find and eliminate the cause of fluid leakage.
- Delamination of rubber material.
- Belt stretch.
Consequently, replacing a belt under normal conditions, when all other units and systems work well and do not cause complaints, is carried out through every 40-50 thousand km, and checking the condition of the belt no less frequently than once every 10-15 thousand km. In this case, the VAZ 21116 engine will cover its service life of 180-200 thousand before overhaul without any problems.
The same applies to engines with an 8-valve head VAZ 11186, which are absolutely identical to the VAZ 21116, but have a cylinder-piston group from Federal Mogul.
Which belt is better to buy for a Grant and for which engine?
The company's belts are installed from the factory on all VAZ engines. Gates. The replacement kit on 8-valve heads has a catalog number K015670XS. We have dwelt in some detail on the topic of choosing the best timing belts for VAZ and VAZ engines, so there is no point in repeating ourselves. There you can also find out how to distinguish a fake from a good quality kit for replacing a timing belt, as well as all the necessary part numbers to search on local sites selling VAZ spare parts.
The Italian-Chinese brand Trialli with article number GD 790 received good reviews from owners More good belts. Which one fits the 8-valve Granta?
As for our Granta, the difficulty in choosing belts for an eight-valve engine is that an ancient but reliable eight-valve engine was installed on old cars and on cars in the Norma configuration VAZ 11183, analogue of VAZ 21083. This engine is good because the valves in it do not bend if the belt breaks. You need to buy it for it belt with catalog number 2108-1006040-10 , and tension roller 2108-1006120.
New Gates belt For the other two Grant engines with an 8-valve block preparation (these are engines VAZ 11186 and VAZ 21116) we buy the following replacement parts:
- camshaft drive belt 21116-1006040 ;
- tension roller 21116-1006226 ;
- If you wish, you can buy a special key for the convenience of adjusting the belt tension 67.7812.9573-01 .
Belt from Continental Of course, for this motor there are analogues from other manufacturers and there are quite a lot of them. Most Popular:
- GATES – 5670XS, like the original, but in its original box;
- Trialli GD 790, Italian brand, Chinese assembly;
- CONTITECH – CT1164, an excellent belt from Continental, if not a fake;
- QUARTZ with catalog number QZ-5670XS, German belts of good quality;
- INA 530053610, one of the highest quality and most expensive kits;
- DAYCO KTB944, a good Italian kit;
- Set manufactured by BOSCH 1987 948 286.
It is important that the belt corresponds to the geometric parameters - belt length 1305 mm, number of teeth 113, belt width 17 mm.
Changing the timing belt on a Grant with your own hands
When we check the condition of the belt or are going to change it, it is necessary that the engine cools down after the trip. The optimal temperature for replacement is about 20 degrees. According to AvtoVAZ, replacement is critically necessary at the 75th thousand mileage, but, according to drivers, it is necessary to change more often. To replace, we need a standard set of tools and a special key for tightening the roller.
If you have all this, let's get to work.
Dear customers, in order to avoid errors when sending p timing belt POWER GRIP 5050 XS , in the "Comment" line indicate the model, year of manufacture of your car andnumber of valves, engine size.
The simplicity of the design lies in the fact that rotation is transmitted from one shaft to another using this part. Each type of engine has its own design features, which is why the belts are produced differently.
Their differences are assessed according to the following parameters:
Length;
Width;
Number of teeth.
The part experiences heavy loads, so it must be strong, elastic, and provide good interaction with the pulleys and rollers.
High strength polyester belt cord« GATES » Increases the belt's ability to withstand heavy loads, maintains consistent belt tension and provides excellent belt length stability. The upper part of the fabric layers provides elasticity and flexibility. Premium fiber-reinforced chloroprene rubber (strong fiber optic tension strands are helically laid to provide increased flexibility and tensile strength) makes the belt resistant to oil, heat and wear and prevents deposit build-up.
Thanks to their successful design, they retain their length throughout their entire service life.
Main technical characteristics
The timing belt profile is trapezoidal and meets the requirements of US, UNECE and Russian GOST standards. The main dimensions of the belts are indicated on the packaging.
The toothed belt has an internal profile of protrusions (teeth), the number of which is 113, with a width of 17 mm.
During the production process, all belts undergo 100% quality control in terms of geometric dimensions and control tensile strength. All stages of production, as well as suppliers of component materials, are certified for compliance with the requirements of the ISO 9001 standard. Identical technologies and materials are used in the production of timing belts, which are supplied to the assembly lines of VAZ, GAZ, UAZ, General Motors, Ford, Daimler-Chrysler, Toyota, Honda and other car manufacturers.
The optimal combination of materials allows for high wear resistance of belts and low noise levels. In addition, the belts« GATES » US can operate over a wide range of tension forces without significantly compromising durability, reducing the risk of belt failure due to improper belt tension adjustment.
Estimated service life of timing belts« GATES » USA – 125,000 km or 2 years.
Monitoring the tension and condition of timing belts must be carried out during each scheduled vehicle maintenance.
Before replacing the timing belt, you need to check and pay attention to the following:
If the belt is damaged, it requires replacement;
Check the degree of tension;
The belt must be dry and clean.
The design has a tension roller; the whistle may be a result of its wear. Replacing the part completely solves the problem.
If the cause cannot be determined, the belt should be replaced with a part from another manufacturer.
Timing belt rupture can be caused by the following factors:
Natural wear and tear (operation was carried out beyond the established period);
The part was initially defective;
Malfunction of pulleys, shafts, tensioners;
Excessive or insufficient belt tension.
The bearing is the most vulnerable part and often fails. Once the belt is removed, it is easy to diagnose bearing failure.
Roller with offset center. When rotating, the belt is tensioned, the degree of tension is fixed using a bolt.
It is important to monitor the condition of the timing belt tensioner roller. It is the roller that makes the tension level of the belt drive optimal.
It is necessary to check the condition of this part and make repairs if necessary.
There are three tension options:
Insufficient;
Excessive;
Normal.

Dear customers, in order to avoid errors when sending the belt tensioner bearing, in the “Comment” line indicate your car model, year of manufacture,number of valves.
VAZ 21116 engines are equipped with a gas distribution mechanism drive with a tension roller, which eliminates the need to check and adjust the timing belt tension, and the service life of the belt itself is significantly increased.
Tensioner roller 3 located under pulley 5 of the camshaft. Designed to tension the timing belt and maintain it in the most stable position throughout the entire mileage. Moreover, we are talking here not only about the averaged indicator, but also about belt vibrations that need to be smoothed out.
1 – crankshaft toothed pulley; 2 – toothed pulley of the coolant pump; 3 – tension roller; 4 – rear timing belt cover; 5 – camshaft toothed pulley; 6 – timing belt; 7 – boss on the oil pump cover; A – mark on the crankshaft toothed pulley; B – mark on the oil pump cover boss;
C – protrusion on the rear cover of the timing belt; D – mark on the camshaft gear pulley.
For the VAZ 21116 tension roller, the mounting hole is located eccentrically (offset from the center by 6 mm). Therefore, by turning the tension roller relative to the mounting stud, the timing belt tension is adjusted.
If you hear extraneous noise from the timing belt when the engine is running, it means the tensioner pulley has started to make noise and will have to be replaced. From time to time it is necessary to check the condition of the timing belt; if cracks appear on it or the belt is stretched, then it also needs to be changed.
Oil getting on the timing belt leads to a significant reduction in its service life. If the teeth on the belt break, it will cause irregular valve timing and possibly cause serious engine damage. A broken belt will inevitably cause the engine to stop. Taking all this into account, on engines with an automatic tensioning mechanism, it is advisable to check the condition of the timing belt, and if defects are found on it, replace it.
During installation, sharp bends of the toothed belt with a radius of less than 20 mm are not allowed, so as not to damage the cord.

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.
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!
