Changing the timing belt on a Lada Granta with a 1.6 16 valve engine

Dear GrantaVody. Tell me who has encountered...

My friend Grant has 1.6 - 8kl. (norm). Mileage 70,000. The timing belt broke - the valves were bent... Question. Since the grant itself, how long is it better to change the timing belt? What is the approximate cost of repairs? in case the belt has already broken and the valves are bent, and the cost of the belt itself.

I read somewhere on the Internet that at 1.6 - 8kl - if the timing belt breaks - the valves do not bend.
RAVE?
The production of a domestic modification of the Lada Granta has been carried out for several years. The car has gained significant credibility due to its acceptable quality and level of performance, as well as the presence of several different configuration versions.

Today we’ll figure out when to change the timing belt, as well as which timing belt is better.

Some general provisions about the belt

The timing belt in any engine serves to ensure timely intake of the prepared mixture and release of exhaust gases. The composition of this node implies the presence of the following elements:

• camshaft and crankshaft;
• the valves themselves with seals, springs, guide bushings and other parts.

Which timing belt is better? The belt mechanism is positioned separately in this mechanism, acting as a connecting link between the camshaft (or two) and the crankshaft. It is the belt drive that is able to ensure synchronization in the functioning of the elements included in the timing kit.

Finding this important element on the engine will not take much effort. To do this, you just need to open the hood of the Lada Granta and you will see it covered with a special casing. This protection prevents contamination and the entry of foreign objects and dirt.

The design of the belt mechanism includes a rubber base and a working inner surface made in the form of teeth with a certain pitch size.

Replacing the timing belt on LADA cars with a 16-valve engine

Currently, all new Lada Priora are available with 16 valve engines. These power units are also installed on some versions of Lada Granta, Kalina, Vesta or XRAY cars. The gas distribution mechanism (GRM) of these engines is designed for the timely admission of the combustible mixture into the engine cylinders and the release of exhaust gases. It is important to regularly check the condition of the belt and replace it if necessary.

What is the replacement plan?

Cars of the Lada Granta model line are equipped with different versions of the power unit. Some of them are not without problems in the event of an unpleasant break in the belt drive. This is caused by a collision of pistons with valves, as a result of which the latter are bent and the engine requires repair.

The possibility of bending (if a break occurs) is not available on the “11183-50” version of the motor, which is equipped with the standard equipment.

Further in this material we will look at versions of motors that have such a feature as bending of valves when the belt drive breaks. And let's try to understand which timing belt is better.

Another important question: when to change the timing belt? To eliminate this unpleasant situation, the manufacturer deliberately regulates the periodic period of mandatory replacement of the specified “consumables”. The answer to the question of how long it takes to change the timing belt from the manufacturer is after 15 thousand kilometers. This requirement applies to both 8-valve engines and their 16-valve modifications.

Even despite the fact that the “21116” modification is equipped with a motor with an imported head, if the belt breaks, a similar sad fate awaits it.

The manufacturer does not recommend independently carrying out the procedure for either checking the condition of the belt or replacing it. And therefore, when the time has come to change the timing belt, you should contact a service center. If it is revealed that the indicated operation was performed manually, there is a high probability that the owner will be deprived of the possibility of warranty service. For self-replacement, the manufacturer provides permission regarding:

• cabin filter;
• a similar element for the intake system.

However, many car owners still carry out the replacement on their own, but not all new drivers know how long it takes to change the timing belt, and also which timing belt is better than the rest.

Replacing the timing belt without special tools

The method can be used if there is no need to change the rollers.

1. Cut off half of the old timing belt with a utility knife.
2. Remove half of the old timing belt.
3. We put a new timing belt on the crankshaft pulleys.
4. We cut the second half of the old timing belt and remove it.
5. Pull the new timing belt onto the crankshaft pulleys until the end.

By the way, according to the survey results, replacing the timing belt on an 8-valve engine is easier than on a 16-valve engine.

The Lada Granta is popular among car enthusiasts in the Russian Federation and many other countries. The power units of this model have a timing belt in the drive of the timing mechanism. Unfortunately, there are cases of its failure, leading to engine breakdowns. Most often, valves bend when they collide with pistons, but sometimes pistons and connecting rods get damaged. All owners of this car model should know when to change the timing belt on a Lada Granta 16 valve, this will help avoid significant costs for major engine repairs.

Recommendations from Lada Granta owners

Many Lada Granta owners, especially those equipped with 16-valve versions of power units, recommend not waiting for the coveted 60 thousand km mark. This is due to the possibility of using low-quality components, which can cause wear of the replaced elements after a mileage of 20 thousand km.

This fact encourages many “Grantavods” to resort to using products with good quality, and many of them, when asked which timing belt is better, answer that from . But we note that there are counterfeits of spare parts of this brand, and therefore it is recommended to purchase items only from trusted suppliers.

When to change the timing belt on VAZ engines?

In the Lada Granta service book for a 16-valve engine, replacement of the timing belt tensioner and support roller occurs at a mileage of 180 thousand km, and for an 8-valve engine at 90 thousand km.
Now AvtoVAZ engines are equipped with high-quality timing belts from well-known brands. It is quite possible that they will work out the declared life, but it is unlikely that the support roller will last such a mileage due to the poor quality of the bearing. There is another part in the engine due to which the timing belt will break much earlier than the declared life. This is a coolant pump (pump), but the service book says nothing about it at all. Currently, AvtoVAZ has modified the pistons for all 1.6-liter engines and now if the timing belt breaks, the valves do not meet the pistons, and expensive engine repairs are eliminated, but the belt can break at the most inopportune moment. For example, when overtaking. If you remove the cover during maintenance and inspect the timing belt, you can see how it begins to crack or tear. If the pump is leaking, then it also needs to be replaced, but often the bearing, which is located inside the pump, is jammed and it is impossible to visually determine its condition. So when and what to change? An experienced auto mechanic advises buying rollers, pump and belt as a set. In a set it is cheaper than separately and replaced at mileage from 50 to 60 thousand km.

Some tips on the replacement procedure

If you set out to replace the component yourself, then you should not neglect some of the recommendations below. In particular, do not forget to observe the interval at which you change the timing belt.

After hanging the belt, its correct tension is required. This is done through the use of a specialized key. Some “figures” will object, they say, we can do without it. However, here it is very problematic to dare to guarantee a high-quality result. The force applied to the belt branch (when rotated at a 90-degree angle), located between two shafts (well-known: camshaft and crankshaft), should not exceed 20 Nm, but it should not be less than 15 Nm. If there is no “fall” within the designated parameter range, this indicates incorrect belt tension. There is only one consequence - a new regulation!

What are the signs of a worn belt?

The indicated factors will allow you to accurately determine the moment when damage begins to appear on the Lada Granta belt, which will prevent its unexpected failure (break). When to change the timing belt, how can you tell if it is worn out?

1. Primary signs include a significant degree of material wear. This fact can easily provoke the “consumables” to slip or break when the load on the engine is insignificant or in conditions of high atmospheric humidity.
2. The appearance of wear is often caused by a violation of the correct position of the roller in relation to the pulley. This can be confirmed by increased heating of the bearing and fabric remnants of worn out cords sticking out to the sides, used to reinforce the rubber base of the belt.
3. The next sign will be the presence of cracks and peeling. The greater the number of these defects, the higher the chance of an early belt break.
4. If the back surface appears excessively hard, it can be revealed by the presence of shine. This factor, associated with loss of elasticity, indicates a loss of sufficient contact between the belt and the pulleys.
5. During operation, the belt surface may lengthen, which can cause it to jump on the teeth of the shaft pulley. Replacing the belt in this case is straightforward.
6. Failure of the roller is a direct evidence of incorrect positioning of the belt in relation to its working plane.

When to change timing belt on Grant

The process of replacing the timing belt on a Lada Granta

Drive belt timing mechanism Car Lada Grant. this is the same consumable material as the drive belt, filters and oils for various components and assemblies. The timing belt needs to be changed from time to time; the mileage per shift is 60,000 km, according to the manufacturer’s advice. But under heavy loads this mileage can be reduced.

Diagnostics of valve timing

To check the technical condition of the timing belt on a Lada Grant car, it is required every 15 thousand km. This is done as follows.

1. Using a jack, the right front of the car is raised so that the wheel can be turned.
2. 4th or 5th gear is disabled.
3. The protective plastic cover is removed from the synchronization mechanism.
4. By manually rotating the wheel, the crankshaft is forced to rotate, which allows you to study the operating condition of the belt on both sides.

If, during a visual inspection, defects are found in the form of rubber tufts, broken teeth or cracks, the belt should be replaced immediately, despite the movement of the vehicle. If the tension is weakened, it must be strengthened. Taking this opportunity, it would not hurt to inspect the generator drive belt installed nearby, the replacement period of which is 30 thousand km, regardless of what condition it is in.

Many experts do not advise exceeding the range of changes by 50 thousand km. The reason is that in addition to the gears, the belt drives the shaft of the cooling water pump, and this may not last that long. As a rule, this happens as follows: the pump bearing fails and pulls out its plug.

Due to sudden overload, the timing belt breaks with unpredictable consequences. The most unfortunate set of events will be interrupted when the valves are open and the piston moves to its highest dead center. Result. bent valves and subsequent engine repairs.

Preparatory stage

Lada Grant can be equipped with 2 types of 8-valve and 16-valve blocks. The difference in timing of these engines is that the 16-valve version has 2 camshafts, respectively, 2 gears instead of one for the 8-valve. In addition, in addition to tension, the mechanism has an additional deflection roller.

They must also be combined with the belt force, since worn rollers can be a prerequisite for the belt breaking or transferring it to the gearbox. Then the valve timing is disrupted, the engine begins to “shudder”, and the power noticeably decreases. The replacement operation is completely accessible to at least some car owners who have the desire and some tools:

• a set of the most popular wrenches and sockets;
• assembly knife (assembly knife);
• flat screwdriver;
• connector;
• round blades with curved pointed ends or a special fork for tensioning the roller;
• fabric gloves.

Timing belt. Resource when change. Just something complicated

Have you ever thought about what affects the life of the belt timing?

? Why can he drive 120.150,000 kilometers in foreign cars?

The latter will not be superfluous, since it is necessary to loosen bolts and nuts in a confined space, and there is a risk of injury to your hands. The work can be done on any level surface or in a garage. There is no need to open the inspection hole, but it is much more convenient if it is there.

Instructions for use

Replacing a belt with a 2190 is not much different from replacing it with a 16-valve unit. Below are instructions for the first type of engine; all differences from the second will be discussed separately. First you need to remove the positive cable from the battery and disconnect the connector from the crankshaft .

Then remove the timing mechanism cover and set it aside. To eliminate errors when installing a new belt, the marks on the engine housing must be combined with the mark on the camshaft gear. This can be done by turning the open key or ring key with the bolt that holds the pulley to the engine crankshaft, taking into account the neutral position on the transmission.

The second method, using a suspension wheel, was described above. When the marks are complete, remove the rubber plug located in the transmission and open the viewing window. The flywheel is visible in it; the mark on it should also coincide with the notch on the body. The next step is to remove the belt from the generator drive pulley. To do this, unscrew the lower mounting bolt of this device, unscrew and remove the upper mounting bolt.

The alternator housing can then be pulled forward and the belt removed from the pulleys. By immediately taking advantage of this moment, you can inspect the removed belt for defects and damage and replace it if necessary. After this, an operation is performed to loosen the bolt holding the crankshaft pulley. It often happens that you simply cannot do this with a wrench, especially after factory tightening. There are several ways.

1. Insert a heavy-duty flathead screwdriver or install it into the flywheel viewing window, blocking it. Using the right-hand screwdriver, remove the pulley bolt using the 17mm wrench on the left.
2. If you have an assistant, the procedure is greatly simplified. One will engage 4th gear, press and hold the brake pedal, and the other will unscrew the pulley. This is much more convenient, both hands are free to work.
3. Some motorists put a cap on the pulley bolt and press it into any element of the body or suspension, after which the crankshaft is started by the starter in neutral transmission. The method is quite dangerous; it can be used as a last resort when it is impossible to loosen the bolt by other methods.

After the bolt is unscrewed, the pulley is removed and the workpiece is wiped with a cloth. Then you need to loosen the tension pulley bolt, the belt tension will be released and you can remove it. Since the roller must also be replaced, it must be unscrewed. The last element to be removed is the bottom cover of the mechanism; it is attached to the engine with three bolts.

This assembly disassembly is complete. Before installing a new timing belt and pulley, make sure that the pump drive shaft rotates freely and is not jammed. Otherwise, you will have to decide to replace the heat pump.

Mechanism assembly

The assembly process is performed in reverse order, only at the very beginning you need to make sure that the marks are installed first. Then a new tension roller is installed and a new timing belt is applied to the gearboxes from the bottom of the crankshaft. Holding the belt in your hand, place it on the camshaft sprocket until all the teeth line up, then tighten using the tensioner pulley.

READ How to Understand That You Need to Change Brake Fluid

There are 2 holes in its body into which you can insert special plugs or pliers and use them to stretch it. Then tighten the medium strength roller. To ensure that the belt is correctly installed and tensioned, it is necessary to perform a couple of full revolutions of the crankshaft, preferably not with the starter, but with the key. Then combine the marks and double check the position of the marks in the flywheel sight.

There is one caveat: the mark on the camshaft gear may deviate a couple of mm to one side or the other from the mark on the housing, which is quite acceptable. If the belt is not fastened correctly, the difference will be 1 cm, this is immediately noticeable. You need to release the tension again and move the belt with one tooth to the right or left, and then repeat the operation. Once the new belt is successfully installed and tensioned, you can assemble the assembly.

When installing the generator drive belt, remember that the VAZ 2190 tensioning mechanism does not exist. Thus, the block body is moved as close as possible to the cylinder block, the belt is put on its pulley and partially on the crankshaft, after which it will be necessary to turn half a turn to install consumables. Further assembly is not a problem, after which you can start the engine. The operation of such a replacement Lada Grant engine with 16 valves is distinguished by the following details.

1. There are two camshafts, the marks will need to be combined and then checked for two gears.
2. It is necessary to replace 2 rollers: tension and bypass.
3. The new belt will need to be carefully placed on the top two gears by passing it through the idler pulley, a slightly more painstaking process.

When working on a replacement, it is recommended to pay attention to the cleanliness of the gas distribution mechanism. Typically, dust, dirt, old belt products in the form of black powder, etc. will accumulate there. Gently wipe the motor housing, gears and protective cover inside.

The whole procedure is quite simple. Knowing how much to change The synchronization mechanism for consumables and a minimum set of devices make it possible for anyone to do it independently.

What are the expected consequences of a break?

As stated, no problems with the Lada Granta engine in the 8-valve version, or if the belt drive breaks, arise only in the version of the “11183-50” unit. The remaining engines are at risk of failure in the event of a designated unpleasant incident. In view of this, a dispute arose among the “Grantavods” regarding the advantages of LADA Granta engines with 16 and 8 valves, and which unit has more of them. Your point of view will also be very interesting.

If the belt drive breaks, the camshaft stops in the position corresponding directly to the moment of failure. In contrast, the crankshaft is subject to continued rotation. This causes the pistons to hit the valves that were in the open position at a given moment. Then the latter bend, but sometimes a breakdown of the piston bottom occurs. Popularly called “fist of friendship”!

It is based on this fact that experts are inclined to recommend changing the timing kit before the period stated by the manufacturer for this action.

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.

1. 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.
2. Next, inspect the outside of this Lada Granta component. Make sure there are no signs of wear, oil, carbon deposits, or threads.
3. 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).

conclusions

Now you know how long to change the timing belt. Undoubtedly, a broken LADA Granta belt is a source of unprecedented problems. This circumstance does not mean that you need to remain inactive. Below are a few recommendations whose goal is to minimize this risk.

1. Be very careful when checking the belt for wear. This action is recommended to be carried out after 10-15 thousand km.

2. Do not neglect checking the condition of the seals. The defect manifests itself in the form of characteristic spots under the bottom of the car.

3. The flashing of the lamp that registers the oil pressure in the LADA Granta engine may indicate a problem. If this fact manifests itself, we urgently turn off the engine and take measures to find the source of the breakdown.

4. Use only original spare parts, although no one has canceled the procedure for monitoring their condition.

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.

AVTOVAZ recommendations

It is immediately worth noting that on the official LADA website in the maintenance calculator (it is only up to 90 thousand km) nothing is said about replacing the timing belt and rollers. However, information about this is in the service book of some LADA models.

Lada Priora:

No information available.

Lada Granta, Kalina:

• The 2015 service book indicated that for the 8-valve engine, replacement is provided at a mileage of 75,000 km.
• The 2021 service book states that the timing belt, tensioner and support roller (if equipped) should be replaced at a mileage of 180 thousand km.
• From June 2021, the timing belt must be replaced at 90,000 km.

Lada Largus:

• Engine Renault K4M (1.6 16V). The timing belt and rollers should be replaced at 120 thousand km or 6 years.
• Engine VAZ 11189 (1.6 8V). The timing belt and rollers should be replaced at 160 thousand km or 8 years. It is noteworthy that the Lada Vesta service book (until 2021) indicated that on the VAZ-11189 engine, replacement is provided at a mileage of 180,000 km (until 06.2021) or 90,000 km (from 06.2021).

Lada Vesta, XRAY

:

• Engine VAZ-21129 (1.6l., 16kl.). The timing belt along with the rollers should be replaced at a mileage of 180,000 km (until 06/2021) or 90,000 km (from 06/2021).
• Engine VAZ-21179 (1.8l., 16kl.). The timing belt along with the rollers should be replaced at a mileage of 180,000 km (until 06/2021) or 90,000 km (from 06/2021).

Conclusion

:

• AVTOVAZ periodically changes the regulations for replacing timing belts and rollers.
• From June 2021, according to the regulations, the timing belt must be replaced at a mileage of 90,000 km.

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.

Removing the timing belt

You will need : a 5-point hexagon, a 17-point, 15-point, 10-point socket and a large flat-head screwdriver.

Procedure:

1. Remove the upper timing cover by removing 5 screws.
2. Remove the lower timing cover by unscrewing the 2 screws. Remove the alternator belt.
3. Camshaft drive diagram.

In order not to disturb the valve timing, it is necessary to set the crankshaft and camshaft to the TDC (top dead center) position of the compression stroke of the 1st cylinder. For this:

1. Turn the crankshaft clockwise using the generator drive bolt until the marks on the camshaft toothed pulleys align with the marks on the rear timing drive cover.
2. check that the mark on the flywheel 1 is located opposite the slot 2 of the upper cover of the clutch housing.

We fix the flywheel by inserting a screwdriver between the flywheel teeth through the hole in the clutch housing. Then:

1. Remove the pulley by unscrewing the bolt.
2. Remove the support washer.

1. Release the belt tension by turning the roller bolt.
2. Remove the belt from the camshaft pulleys, tension and support rollers.

After removing the timing belt, the crankshaft and camshaft cannot be turned. When replacing a timing belt, the tensioner and support rollers of the belt also change.

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.

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.

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.

Consequences of a broken toothed belt. Is everything really that scary?

The manufacturer installs several types of power units on Grant cars.

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 long does it take to change the timing belt?

• According to the Lada Priora maintenance regulations, the condition of the timing belt should be checked after 105 thousand km, and replaced after 200 thousand km. However, sheared teeth or a broken timing belt can cause the valves to stick (valve bending) into the pistons, leading to costly engine repairs. Therefore, we recommend checking the condition of the timing belt more often - every 45 thousand km.
• On Lada Granta and Lada Kalina 2 cars, the timing belt is checked every maintenance (every 15,000 km), and replacement is carried out after 75 thousand km. mileage

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.

Timing for replacing timing belts

When the question is raised about the frequency of belt replacement, first of all, we mean the maximum period during which the belt retains its properties. At the same time, the probability of its stretching and breaking, which can lead to serious damage, is calculated.

There are special programs (AUTODATA, ELSA and others) that clearly establish the timing of routine maintenance, including the replacement of belts and rollers. However, these programs do not take into account the operating conditions of the car and available components. Ordinary drivers and most non-dealer service stations are guided by the established operating life and mileage of the car. It's better to judge by mileage. Many people estimate the period for mandatory belt replacement based on mileage to range from 50,000 to 80,000. However, if the car is used little, its annual mileage is, for example, 5,000 per year, this does not mean that the belt must be replaced every 10 years. The maximum service life of a car without replacing the timing belt is usually 5 - 7 years (subject to mileage conditions).

It is also necessary to take into account the characteristics of the engines. If the engine has two camshafts, there are more valves, and accordingly, greater loads are placed on the belt.

At the same time, the tension roller (or mechanism) and guides should be changed along with the timing belt. In most cases, adjustment of the ignition angle is required. Modern engine control systems block engine starting if the ignition angle is incorrect. This is done to ensure that when setting the wrong angle, accidental starting and destruction of the timing system does not occur.

When determining the timing of belt replacement, it is necessary to take into account operating conditions and vehicle mileage. If the machine is operated in conditions of extremely low or high ambient temperatures, the replacement period must be reduced by 10 - 15%.

In order to reduce the likelihood of abnormal timing belt damage, you should:

• monitor the integrity of the protective casing;
• do not allow foreign liquids, oils, or objects to get into the belt area;
• observe the frequency of routine maintenance.

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. Adjust 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:

Step-by-step instructions for replacing the timing belt

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.

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.

Belt tension

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.

Installing a new timing belt

Attention! The tension roller has a tension direction mark.

Tension direction.

1. We put the tension and guide rollers in place. We tighten the guide bolt, there is no tension.

1. We check that all marks match. If the marks on the camshafts have moved apart, tighten them with a 17mm wrench. Install the new timing belt in the following sequence: first on the crankshaft sprocket and pump, then on the guide roller, camshaft sprockets and tension roller. We turn the tension roller with a special key, in accordance with the direction of tension.

1. We ensure that the marks on the roller match, and tighten the bolt securing it. Head 15.

Correct tension.

1. Instead of a wrench, you can use a circlip puller. Shown in the filmed video.

1. We turn the crankshaft two turns and check all the marks again. If everything is in order, reinstall all the parts in the reverse order of removal. Fill with antifreeze.

Everything is very simple.

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.

Reviews

And you can decide which timing belt for the Grant is right for you based on reviews from the owners of this car.

Oleg: after running into a Boshev counterfeit, I prefer products from a domestic manufacturer. This is the second time I have bought a BRT belt. It runs the required 75 thousand without any problems. I recently changed the tension roller. I installed the Vologda one, let's see how it performs

Vitaly: I prefer not to skimp on spare parts, so I only install from the German manufacturer Gates. You can feel calm with it even on a long trip.

Slava: the most reliable and proven option is the manufacturer Contitech. Although it is more expensive than Bosch, the quality is many times better. My friend (his Kalina) and I bought it at the same time. He took something cheaper, made in Russia. The salespeople talked me into talking about Contitech. I'm very pleased, because my friend threw his away a long time ago, and I still drive it. Although it looks like new, I’m thinking of changing it, it’s already done more than 130 thousand. I'll take the same one.
