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.

Next, use the same 5mm hexagon to unscrew the bolts securing the lower timing case cover and remove it.

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. Neither nail nor rod

Timing belt Lada Granta: general characteristics and problems

The timing belt on Grant is a ring-shaped product with special teeth, the number of which is strictly defined. A product with a rubber base, reinforced with nylon threads, ensures the transmission of torque from the crankshaft gear to the camshaft.

The timing belt of a Lada Granta with an 8-valve internal combustion engine should have 113 teeth and a width of 17mm. The performance of the gas distribution mechanism, which is responsible for valve timing, depends on the condition of the timing belt. According to the regulations for scheduled vehicle maintenance, the Grant timing belt is replaced every 60-75 thousand kilometers.

If we consider the Lada Granta model, the Granta timing belt is very important for the operation of the internal combustion engine on this car, as it ensures an uninterrupted operation cycle of the intake and exhaust valves. In the event of failures or malfunctions, the entire cycle is disrupted.

The main faults associated with the timing belt:

• If the timing belt of the Lada Granta 8 valves breaks, it will cause the car’s internal combustion engine to stop, but will not damage the valves and pistons (on the 8-valve internal combustion engines Granta 11183 of the first generations, the design allows the pistons and valves not to hit when the belt breaks). However, other engines on this model (for example, 11186) can no longer boast of this and bend the valves.
• The Grant 8-valve timing belt, as well as on other modifications, begins to slip if oil and other working fluids get on the surface. The same thing will happen if the belt tension is poor. As a result, a shift in the phases and angle of rotation of the camshaft occurs, which leads to disruption of the internal combustion engine, overheating occurs, power drops, etc.

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:

1. Decrease in vehicle power. A poorly tensioned or worn drive can make the engine difficult to start and reduce power output.
2. 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
3. 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.

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.

1. 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.
2. Then inspect the external part of this Lada Grant component. Make sure there are no signs of wear, oil, sludge, threads.
3. 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 will not be needed anytime soon, so please examine the new part carefully before purchasing

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).

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:

1. Start the engine, warm it up to normal operating temperature (usually this indicator varies from 87 to 100 degrees).
2. 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

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.

With a relatively small annual mileage of the car, you should also carefully monitor the condition of the timing mechanism parts. The belt ages even if the engine is not running, so it is inspected at every maintenance. If even small cracks are noticed, the delamination changes. The optimal time to replace the timing belt in the timing mechanism drive will be a mileage of 50–60 thousand km.

Recommendations from Lada Granta owners

You can find a lot of material on this car model on the Internet. Lada Granta owners (call themselves grant owners) talk about their cars and give recommendations on how to properly recommend a car. Drivers of 16 valve Grant recommend not to wait until the mileage is 50–60 thousand km, but to change the drive earlier. On the Grant 8 valve, if the drive in the “83” engine breaks, no damage to the valves occurs; for other modifications of the power unit, this can result in an expensive engine overhaul. You should not skimp on replacing the tension roller or coolant pump; they are the ones that most often damage the belt teeth.

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.

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;

Automation will work to weaken11183

– use a 17mm 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

Risk of a faulty timing belt for the engine

A timing drive failure can have serious consequences. At the very least, the engine will fail. And the best way to fix this problem is to contact a car service center.

The severity of the consequences of this failure depends on whether such a case is provided for by the engine manufacturer. On some models, when the belt breaks, the valves collide with the pistons in the combustion chamber. These elements are destroyed, after which the engine may become unsuitable for repair.

Some manufacturers make recesses in the pistons for valves or make a specially shaped combustion chamber in case of a belt break. In such motors, “meeting” does not occur. And all that is needed is to install a new belt and adjust the valve timing correctly.

The Auto-Master car service center (gate No. 5) will replace the faulty timing belt on your car with a written guarantee of the quality of the work performed! Make an appointment with us by phone or using the form below.

The timing belt of any modern engine is usually designed for a short service life. On average, it operates for 50-100 thousand kilometers, after which it requires replacement along with the tension rollers, and often also the water pump and pulleys. The timing of replacement of this important part is strictly regulated and specified in the operating instructions for each specific vehicle. However, by blindly following the manufacturer’s recommendations, you may not notice the impending disaster and run into serious and expensive engine repairs. There are several signs that the timing belt urgently needs to be replaced with a new one.

Why do you need to change the timing belt?

First, let's figure out what a timing belt is and why it needs to be changed. This inexpensive and uncomplicated, at first glance, part is needed in order to synchronize the operation of the ignition system with the stroke of the pistons and valves. The timing belt rotates on the crankshaft and camshaft (or camshaft) pulleys, simultaneously driving the water pump. It has a multi-layer reinforced structure and consists of rubber and nylon base. The correct belt tension is set by a special roller. When the timing belt breaks on most modern cars, the intake and exhaust valves meet the pistons. A serious breakdown occurs that is incompatible with further movement and requires complex, expensive repairs.

The timing of replacement of rubber products and related components depends not only on the make and model of a particular car, but also on operating conditions, which in our country are very harsh. However, this does not prevent some brands from installing prohibitive timing belt service life on their products. For example, on domestic Ladas this operation should be carried out once every 180 thousand km. This figure looks, to put it mildly, too high. For comparison, on Renault cars, even the highest quality belts from the world’s best manufacturers last 60 thousand km in Russia and 120 thousand km in Europe. Experiments with non-compliance with this regulation are fraught with big troubles.

Signs of timing belt wear

The main problem that prevents you from noticing impending trouble in a timely manner and preventing the timing drive from breaking is difficult access to the part: unlike the belt of mounted units, this belt is carefully covered with all kinds of casings. To perform an inspection, partial disassembly of the engine is often required, which most car owners are not able to perform. However, in addition to tears and cracks that are visible visually, there are other symptoms of impending disaster. We will try to list the most common ones.

1. Belt is old

Basically, the service life of a timing belt is determined by the mileage of the vehicle. After several tens of thousands of kilometers, it must be replaced. However, there is one “but”: age is also critical for this part - on average, the belt retains its properties for no more than five years, after which it begins to lose elasticity and crack, regardless of mileage. Drivers who drive a car relatively rarely should pay close attention to this point. The belt consists of materials that are subject to rapid aging, which means you shouldn’t joke with its age. For the same reason, we recommend that you change the timing belt on purchased used cars without fail - no one guarantees that the previous owner complied with the regulations and used high-quality components.

2. Uncertain engine start and loss of power

When to change and how much does it cost?

Replacing the belt drive in a timely manner is important. It transmits rotation from the crankshaft to the gas distribution mechanism. The shafts of this device distribute the gases and fuel mixture.

Factory specialists have established the frequency of replacing the drive after 180 thousand km. But in practice, car service workers advise not to wait for this time, but to replace the belt when the mileage is 100 thousand km or less. This is due to the insufficient quality of the part, as there are many counterfeit parts.

If the belt slips, gas mileage will increase and power will decrease. Particularly serious consequences can be caused by its breakage, which will immediately lead to damage to the valves and pistons. This occurs due to them meeting each other and bending the valves. Repairs after such a malfunction will be expensive.

The drive must be replaced in a timely manner. Such work in a car service costs approximately 6,000 rubles and more. Therefore, it makes sense to replace the timing belt with your own hands, following the operating technology. To do this you will need a set of tools.

Explanatory video on where to look for tags

The gas distribution mechanism is one of the most important systems of an internal combustion engine. The timing belt controls the engine valves, ensuring the normal functioning of intake and exhaust. During intake, the fuel-air mixture enters the combustion chambers as a result of the opening of the intake valve. The next phase opens the exhaust valve, and the gas distribution mechanism removes exhaust gases from the combustion chamber. The VAZ 2190 uses a standard gas distribution unit, differing only in the number of engine valves.

Engines Lada Granta

Lada Granta cars are equipped with several types of VAZ power plants. There are 5 of them in total, these are:

• 11183-50;
• 11186;
• 21126;
• 21127;
• 21126-77.

In almost all modifications of the Lada Granta internal combustion engine, if the timing belt suddenly breaks, the valves will bend.
This does not happen only on the eight-valve engine with serial number: 11183-50, which was installed on the standard Granta from the very beginning of its production. However, here, too, everything depends on the engine speed at the moment the belt drive fails. There have been cases when serious problems appeared on this unit after it broke. Another 8-valve engine, which received the index 11186, not only bends the valve when the timing belt breaks, but can also cause damage to the pistons and connecting rods. In the best case, if the belt drive breaks on this installation, the intake valves bend.

The sixteen-valve engine 21126 is a modified version of one of the most popular internal combustion engines from VAZ - 21124, and many experts consider it the best of all that are equipped with Granta, but it also bends the valves due to the lack of recesses for the pistons.

The modified unit 21126, which received the factory index - 21127, was also not without the problem of valve bending, however, like the engine 21126-77 (installed in the Lada Granta Sport). How long is the timing belt life expectancy on Grant models?

Preparatory operations, all engines

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! Read more about engine 21116 in this material.

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.

Unscrew the 4 bolts and remove the protection

To remove protection you need:

• 11186/21116 - using a “5-point hexagon”, unscrew the 4 bolts on the upper 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.

Disconnect the connector, unscrew one screw

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.

Inspection window and rubber plug

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.

Flywheel fixed

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).

Timing drive in 8-valve engines

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.

You need to turn the generator drive pulley

The alternator belt needs to be removed

The alternator belt blocks access to the timing drive parts. You will have to loosen the fastening and remove this belt.

More about this:

• We change the alternator belt on a Lada Granta with air conditioning;
• We change the alternator belt without tensioner on the Lada Granta.

Generator mounting, 13 bolts

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;
   Installation of the alternator belt, first step
3. Having engaged 5th gear, roll the car back.

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!

Replacement procedure

Many owners of this car prefer to carry out this operation in specialized workshops, but some do it themselves. There is nothing overly complicated in this procedure; there is no need to purchase special equipment or devices. You can replace the timing belt yourself in the garage. You will need to prepare a set of wrenches, a mounting shovel, a jack, a stand for the body, wheel chocks, gloves, and rags. Round nose pliers with curved ends are suitable as a key for adjusting the tension roller.

Replacing the timing belt on a Lada Grante is performed in approximately the following sequence:

1. The car is placed above the inspection hole or on a flat surface, the handbrake cable is tightened, and wheel chocks are installed under the rear wheels.
2. Open the engine compartment hood and disconnect the terminals from the battery.
3. The generator set drive belt will interfere with work, so it is removed.
4. Now, using the hex number “5”, remove the four screws that secure the front protective cover of the gas distribution mechanism drive.
5. To avoid accidentally damaging the crankshaft position sensor, it should be removed from the cylinder head and set aside. Do not allow metal filings to come into contact with the sensor; they may further distort its readings.
6. Next, you need to set the piston of the first cylinder to the top dead center position.
7. Removal of the toothed belt is hampered by the generator drive pulley on the crankshaft, which must be removed. To do this, tear off the wheel bolts of the right front wheel and raise the body with a car jack.
8. A stand is installed under the body, the wheel is removed, and the protective shield is on the mudguard.
9. An assistant is needed to remove the crankshaft pulley. Ask him to engage fifth gear and press the brake pedal hard. Some experts insert a powerful screwdriver into the hatch on the transmission housing between the teeth of the flywheel.
10. Applying some force to the head “17”, unscrew the bolt and remove the pulley from the crankshaft.
11. You will again need the fifth hexagon number, with which you need to unscrew the three screws of the lower protective casing of the timing mechanism, after which you can remove the protection.
12. Now you need to loosen the tension roller fixing bolt; a 15 mm spanner is best suited for this. After this, the roller will rotate and release the tension of the drive belt, which is easily removed from the gears and taken out of the engine compartment.

Important! After this, you cannot turn the engine crankshaft to prevent the pistons from meeting the valves.

Typically, the belt is replaced together with the tension roller and coolant pump, so they must be removed from the cylinder block. There is an adjusting washer under the roller, which is installed back during assembly. When removing the pump, pour a certain amount of antifreeze into a previously prepared container. Installing a new timing belt is carried out in the reverse order.

Please note that you need to check the position of all installation marks on the crankshaft and camshaft, cylinder block and timing case.

Setting marks

This is an important procedure when replacing the timing belt, so it must be taken seriously. This engine has four timing marks in the timing drive. Two on the crankshaft and camshaft gears, one on the cylinder block in the crankshaft area, the last one is on the metal protective casing. Two more marks are located on the flywheel and gearbox housing. They will be clearly visible when the rubber plug is removed. It is the marks of the flywheel and the box casing that will indicate the position of the piston of the first cylinder at top dead center.

Turn the crankshaft with a key to “19” clockwise until all the marks of the mechanism coincide. The camshaft pulley mark in the form of a conical recess or boss will be in a horizontal position and coincide with the protrusion on the protective casing. The mark on the crankshaft pulley will look strictly vertical and coincide with the mark on the cylinder block.

The installed new timing belt must be tensioned to the required parameters. Before doing this, be sure to check the position of the installation marks again; if everything is in order with them, you can tension the drive. To do this, you need to turn the tension roller counterclockwise until the marks on it match. There is one mark in the form of a cutout on the outer frame, the second on the inner one in the form of a protrusion. You can turn the tension roller with a special wrench or pliers.

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.

Stages of work

1. First, remove the negative terminal of the battery.
2. Remove the generator belt drive.
3. We fix the car using stops; decide for yourself which ones are best suited for this.
4. When we lift the car with a jack, remove the right front wheel.
5. Remove the gas distribution mechanism cover.
6. The piston of the 1st cylinder should be set at the highest point.
7. We loosen the belt tension using a tension roller or bolt.
8. Loosen the tension roller nut.

9. 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.
10. Remove the generator drive pulley.
11. Remove the bottom cover by first unscrewing the three bolts.
12. We remove the timing belt drive from the camshaft and crankshaft pulley.
13. If necessary, remove the timing belt tension roller.
14. We carefully examine it, and if we find that its condition is unsatisfactory, we change it.
15. We also inspect and, if necessary, replace the belt.
16. 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.

1. 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.
2. Next, you need to align the marks of the camshaft pulley and the marks located on the rear cover.
3. We fix the pulleys with the device described earlier.

   Fixing pulleys

4. We align the marks on the crankshaft pulley and on the oil pump cover.
5. We turn the crankshaft with a wrench in the shortest angular direction.
6. We tighten the bolt securing the auto tensioner.
7. We put the belt drive on the support roller, pulleys and auto-tensioner.
8. We install a special key for tensioning the belt in the grooves of the auto-tensioner support plate.

9. Turn it counterclockwise until the first and second marks coincide.
10. Tighten the bolt securing the tensioner. The tightening torque should be approximately 2.4/3.5 kgf. m.
11. Remove the crankshaft lock and turn it a couple of turns.
12. 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.
