Most likely, every car owner knows what a timing belt device is, but beginners may not fully understand its purpose. So, this belt properly distributes the work of the drive, so to speak, between the gas distribution mechanism, which is abbreviated as the timing belt, and between the special toothed pulleys in the crankshaft. The device is made of high-strength rubber, and on the outside it has a toothed base, which allows you to create movement during operation. Most main question in this matter: how long does it take to change the belt? The automobile manufacturing company AvtoVAZ, which produces the Lada Vesta, regulates replacement every 200 thousand kilometers. In this case, it is necessary to take into account the fact that if the belt was manufactured without compliance technical standards, then its service life is reduced significantly. And then the car owner must take care to replace the timing belt in advance, otherwise, due to a malfunction, the belt can easily bend the valves on the power plant.

Can a broken timing belt bend the valves?

Many owners of a car from the Russian Federation Lada Vesta, and other models, are worried that due to the fact that the timing belt was not replaced in a timely manner, this can lead to bending of the valves, and in order to repair them they will have to pay a tidy sum. This is true. Experts say that in car power units that come with a timing belt from the factory, in most new car models, unpleasant valve failures often occur.

The design of the Lada Vesta engine with a power rating of 122 hp will in most cases bend the valves when the belt breaks. Even the fact that at one time, to eliminate this unpleasant situation, grooves were introduced into the piston itself will not help. The depth of these very grooves is not sufficient, and a torn belt easily bends the valves. Avtovaz's creators of the popular domestic car changed the piston system, but did not succeed in this matter. All the same, the valve mechanism came out of order due to the timing belt falling off. And there is only one panacea: timely replacement of the timing belt. And we told you when to change it at the very beginning.

Important!
Cars domestic production Lada Vesta valves are bent only if there is a belt on them. There are models that AvtoVAZ produces with Nissan engines, in which there is always a chain connection. Consequently, there is no impact on the valves and the chain will never break at one moment, it will gradually fail.

Step-by-step instruction timing belt replacement in Vesta ( necessary tools)

• Russian Lada Vesta install on a lift.
• We remove only one negative terminal on the battery.
• We dismantle the starter and, accordingly, the belt drive car generator.
• Now lower the lift completely.
• A traverse is carefully installed on the right side of the engine.
• Lift the motor using a hook.
• Using Torx 12 sockets, remove all bolts. A hexagon wrench will be required to unscrew the 8 fasteners, which are located on the protective special casing of the drive (3 on the bottom, 5 on top).
• The following steps when replacing the timing belt entirely depend on what type of unit is in the car. To do this you will need a matching diagram.
• The video material will clearly tell you about all the subtleties that will prevent valve failures.
• After installing a new belt, it is necessary to adjust the tension, and then check the functionality of the entire system.

Let's sum it up

Replacing the timing belt directly in the Lada Vesta model we have designated today is a painstaking and responsible task, but it is quite possible to do it yourself, rather than turning to auto mechanics for help. And some drivers wonder: belt or chain? It cannot be ruled out that the chain, which is a more durable device and does not bend the valves, may one day replace the belt in Vesta.

The timing belt drives the camshafts and valves in accordance with the positions of the pistons. If you do not take care of this unit, there is a high probability of complete engine failure followed by expensive repairs. What could happen?

A worn belt can break, and a worn tension pulley can cause the belt to slip through the teeth. All this disrupts the position of the valves relative to the pistons, which can lead to their “meeting,” which usually results in bent valves and camshafts broken into several parts.

If you do not want such consequences, then the only correct solution is to timely replace the timing belt and tension pulley. To perform this procedure in a Lada Vesta car, use the instructions given below.

Removing the timing belt

To remove the timing belt, you must perform the following steps:

• Remove the terminal from the battery
• Raise the car on a lift
• Remove the accessory drive belt
• Remove the crankshaft damper, first stopping the rotation with a screwdriver or special tool, then tighten the crankshaft bolt

• Unscrew the 2 bolts securing the right support to the internal combustion engine (Torx E12), having previously suspended the engine on a traverse or other device

• Unscrew the remaining 2 bolts securing the support to the body (16 mm head) and remove it

• Remove the timing belt guard by unscrewing 5 bolts (5 mm hexagon)

• Rotating the crankshaft, align the camshaft marks at the same level with the marks on the rear cover

• Loosen the tension roller bolt with a 17 mm wrench

• Remove the timing belt

For convenience, use a special tool: a camshaft clamp and a crankshaft clamp.

Installing the timing belt

The timing belt must be installed at an engine temperature of +15 to +35 C⁰. Otherwise, there is a high probability of incorrect adjustment of the timing mechanism, which can lead to unstable work engine, reduced power and increased consumption. So, in order to correctly install the belt and adjust the gas distribution mechanism, follow these steps:

• Align the mark on the crankshaft pulley with the mark on the oil pump

• Align the marks on the camshaft pulleys with the marks on the cover
• Tighten the tension roller bolt to 5 Nm
• Carefully, without disrupting the valve timing, slide the belt from the upper pulleys to the lower one.

• Using a special wrench, adjust the tension roller

• Tighten the tension roller bolt (15 mm head) to 33 Nm
• Make sure all marks are in place and turn the crankshaft pulley 2 turns
• Reassemble all components in the reverse order of removal.

When to change the timing belt

The timing of replacing the timing belt on the Lada Vesta, as in other cars, depends on many factors. The manufacturer recommends performing this procedure every 90,000 km, however, given possible consequences breakage, it is recommended to replace it much more often. Especially if your car's engine has significant mileage. Any oil leaks, water splashes and dirt can significantly reduce the life of the timing belt. So how much mileage does it take to replace? – we recommend changing it every 50,000 km.

We answered questions about how to replace and after how long to change the timing belt on Vesta. If you still have questions about a procedure such as replacing the timing belt on a Lada Vesta, videos and photos on the Internet will help you answer them. And remember a very important point - diagnose the condition of the timing belt as often as possible, because a broken timing belt can lead to considerable financial and time costs.

A timing belt is a part made of rubber with notches with inside, connecting the crankshaft and camshaft to ensure vehicle movement. The responsible owner of a Lada Vesta, who has driven more than 50 thousand km, had to replace the timing belt at least once - so as not to find out prematurely whether the valves are bending.

Unfortunately, on the VAZ this ailment is transmitted from engine to engine, they cannot work on it in any way and the valve is bent due to the assembly: belt, rollers.

This unit is vulnerable and the valve will bend if one of these parts fails. The situation would have changed, or not, the problem would have gone away completely - install the AvtoVAZ pump separately, but alas, the pump is in one unit on all VAZ engines.

If the hr16de engine had entered the series, then this ailment would also be absent, you would only need to undergo maintenance on time, monitor the chain, and yes, valve adjustment, VAZ engines would again come into use.

After a significant mileage of the car or not correct operation The timing belt often breaks. Oil getting on the surface, untimely replacement of components, use of the car in severe frosts or, conversely, in sultry heat - this can damage the gas distribution mechanism drive.

Damage can be detected by maintenance Frets of Vesta. Maintenance consists of inspecting the condition of the unit from time to time.

Quite a significant problem for Vesta owners with 16 valve engines if it breaks, the valve bends. This happens after the timing belt breaks or the links are stretched. When the links are stretched, the crankshaft continues to work, but the camshaft abruptly stops its movement. Then there is an absolute stop car engine. If you start it again, you can cause failure of the pistons, which will cause expensive repairs piston group cylinder block.

Read the article and your engine will be safe - you will replace the belt and rollers on time, preventing unexpected breakdowns.

Lada Vesta: When to change the timing belt, frequency and cost of repairs.

The vehicle's registration certificate provides for replacement of the unit after 180 thousand kilometers.

In practice, it is advisable to change the drive more often - after 80-100 thousand km, because the part does not always correspond to the original production.

The cost of replacement will be calculated taking into account the work of specialists and the cost of the part. Usually the cost of work is 3000-5000 rubles, and the price of the part depends on the manufacturer.

So, the average price:

• CT 1179 (CONTITECH) - from 1000 rubles;
• 5671 XS (Gates) — 3890 RUR;
• GATES K015631XS 16 class — 3890 RUR;
• Bosch 1987949686 (Bosch) - 1360 rub.
• Trialli GD770 - 2900;
• Lynxauto PK1300 - 2430 rubles per set.

Standard belt from factory

The frequency of replacing the timing belt unit of a Lada Vesta car is about 90-100 thousand km.

A resource is the frequency through which a node needs to be changed. The service life of the Gates model is approximately 200,000 km. It is important to consider that the service life of the timing belt is also influenced by external factors, including proper operation.

For some car models, including Lada Vesta, belts are supplied by the well-known Belgian company Gates.

It is better to buy a kit, along with a tensioner and a regular pulley.

The car comes with Gates or Contitech parts from the factory.

Replacement tool - you need to know

To replace the timing belt on a Lada Vesta, you need the following tools:

• inspection hole or overpass;
• socket wrench "17";
• hexagon “5mm”;
• Torx E12, wrench “10” and “15” mm.
• New belt, tension pulley and 2nd pulley.

Replacement Timing belt Lada Vesta can be done on your own.

Instructions for replacing the timing belt on Vesta

You can carry out work to replace the timing belt on our own, but this is labor-intensive work.

Replacement requires the necessary technical equipment and experience in carrying out repair work.
At the beginning of installation and adjustment of the belt drive, you should remove its casing on the engine by removing the 5 fastening screws.
Remove the casing and remove the belt.
Using a 17mm wrench, turn the crankshaft using the roller bolts so that the marks on the camshafts coincide with the marks on the plastic casing. Turn until the crankshaft pulley with mark F coincides with mark E.
Using the same key, the crankshaft pulley and limiter washer are removed.
The remaining part of the casing is unscrewed with a 5-point hexagon: 2 bolts on the bottom and 3 on top.
Using a 15mm wrench, unscrew the tension roller mounting bolt, after which it is dismantled in the same way as the idler roller. New rollers are put on in their place.
Then comes the installation of a new belt instead of the old one. First you should make sure that the marks are still set correctly, then the belt is installed on the camshaft and pulled to the crankshaft with tension. The timing belt tensioner pulley starts it last.
Use a snap ring puller to rotate the tension roller until the marks are compatible.
Next comes the assembly.

Replacement on motor 21179

The new timing belt is installed in the VAZ 21179 unit in the same way as disassembled earlier.

Analogue belt brands

If we talk about the most best brands, then Gates, Contitech, Dayco and Bosch are the most promising in the segment and enjoy decent popularity.

Drivers trust spare parts from the Belgian company Gates, whose manufacturers supply their products to car factories.

An analogue of Geitz is the German company Contitech; its parts are also used during vehicle assembly.

When choosing timing belts, you should choose the original, which may be more expensive in price, but will last a long time. We wish you that your timing belt never breaks and is serviced on time!

Lada Vesta is a compact small class sedan, located on the border of B and C classes, which began its history in 2015.

The following features of the car can be noted:

• Engine for 87–114 Horse power(depending on the configuration).
• Cars are equipped with both engines with a timing belt and a chain.

One of the main machine maintenance procedures is replacing the timing belt, which is a consumable item that gradually wears out. If you do not replace it on time, the belt may break sooner or later, which leads to bending of the valves. In this case, you will have to carry out large-scale repairs - install new valves, their guides and pistons. This long and costly process can be avoided if you check the timing mechanism in time and replace it as necessary.

Vesta is available in variations with four different engines, which differ in volume and power:

• VAZ-11189 volume 1.6 l torque 140 N. m and power 64 kW/87 l. With.
• VAZ-21129 volume 1.6 l torque 148 N. m and power 78 kW/106 l. With.
• VAZ-21179 volume 1.8 l torque 170 N. m and power 90 kW/122 l. With.
• HR16DE volume 1.6 l torque 153 N. m and power 114 l. With.

Three variations were created and produced by AvtoVAZ itself, and the fourth model is a product of cooperation between Renault and Nissan, which differs from others in the presence of a mechanical chain instead of a timing belt.

Belt motors

Let's look at three versions of the Lada Vesta engine, equipped with a standard timing belt.

• VAZ-11189

This model is the weakest of all available in the West and is a classic eight-valve. One of the features of the engine is its simplicity. Power is 64 kW/87 hp. pp., which is 27 less than the maximum version. And when it breaks, the valves bend.

• VAZ-21129

The engine is an improved modification of the 21127 engine; it uses 16 valves. If the timing belt breaks on this engine, the valves bend because there are no grooves for them. The recommended timing for replacing the belt is 90 thousand km.

• VAZ-21179

This variation is the leading one among car configurations with a timing belt. The 1.8 liter engine has increased power and 16 valves. It is equipped with a special mechanism for adjustable timing phases, which is a forced rotation of the cam shaft depending on engine operation. But unfortunately, a broken timing belt also leads to bending of the valves.

Chain motor

One of Vesta's engines has chain drive Timing belt This is a 1.6 liter Renault-Nissan H4M-HR16 DE engine. It also has an automatic valve timing system. The main problems are chain stretching and tensioner failure. If tension problems do not arise, the chain will never need to be changed.

Timing belt replacement algorithm

Replacement with 21129

Main replacement steps:

1. Disconnect the battery.
2. Remove the right wheel, fender liner, and engine mudguard.
3. Loosen the accessory drive pulley bolt and remove the accessory drive belt.
4. Remove the engine cover and right mount.
5. Remove the timing cover by unscrewing the five bolts.
6. Remove the accessory drive pulley.
7. Remove the crankshaft disc and front timing cover.
8. Check the alignment of marks A, B, C, D. If necessary, rotate the crankshaft. Check that the mark also matches on the crankshaft pulley.
9. Loosen the tension roller and remove the timing belt, starting at the camshaft pulley.
10. Replace the tension roller without fully tightening the bolt.
11. Install the new timing belt, making sure the timing marks match. Perform all steps in reverse order.
12. Tension the belt by turning the pulley clockwise until its cutout aligns with the rectangle.
13. Turn the crankshaft 2 turns. If the marks still match, the adjustment has been made correctly.

Replacement with 21179

The timing belt on the 21179 engine should be replaced every 180,000 km, and the pump must also be changed along with the belt. It is believed that the service life of the pump is similar.

It is difficult to replace a motor yourself for several reasons:

1. There are no markings on the pulleys on this motor.
2. The camshaft must be fixed with a tool, which is also quite difficult to install.
3. It is necessary to disassemble a large number of parts to get to the gas distribution mechanism.

To carry out work on replacing the timing belt, you will need to disconnect the lower and upper engine mounts, remove the generator, plastic intake manifold, valve cover and disc.

Since there are no marks on the crankshaft and camshaft, they must be fixed with special tools.

There are slots on the camshaft; their correct location is vertical, parallel to each other.

To secure the crankshaft, you must also use a special tool that will secure the gear through the crankshaft bracket.

Once the crankshaft and camshaft are fixed, you can replace the timing kit in the usual manner.

Replacement with 11189

Replacing the belt on engine 11189 is the easiest of all Lada Vesta engines.

1. Disconnect the battery.
2. Remove the right front wheel.
3. Check that the marks match.
4. Remove the timing belt protective cover.
5. Remove the alternator belt pulley and loosen the tension roller.
6. Remove the timing belt.
7. Install the new tension roller without fully tightening it.
8. Install the new belt, starting at the camshaft pulley.
9. Set the required tension by adjusting the roller.

Which belt to buy

One of the important points when replacing a timing belt is choosing a new one.

On the VAZ-11189 engine, the standard part is numbered 21080100604082, with a standard price of about 300 rubles. It is produced in Poland (Gates company). The most popular analogue would be part VT25009 from China (VKT company), whose price varies around 250–300 rubles.

On the VAZ-21179 and 21129 models, the factory standard will be part number 8201069699, with Renault symbols. Country of manufacture – Poland (Gates), the price is in the range of 1100–1300 rubles. Three options will be proven analogues on vesta without negative reviews:

CONTITECH CT 1179- a German-made part, the quality is not inferior to the original, and the price is 2.5 times cheaper (760 rubles). Is more often used than the original.
Gates 5671 XS – Polish part, price around 1250 rubles. Problems in operation or quality are rare, the parameters are completely similar to the original part.
Bosch 1987949686– version from Germany, price about 800–1000 rubles, a well-known world brand. Mainly used in Renault cars.
Belt replacement interval

What are the dangers of incorrect installation?

Improper replacement of the gas distribution mechanism on a Lada Vesta can lead to damage to the valves in the event of a break. And also, this leads to faster wear of all engine parts associated with the timing system. If you are not confident in your abilities, you should seek the help of a specialist. This will cost approximately 5–6 thousand rubles.
