Replacing the timing belt Lada Granta 16 valves: video instructions

Lada Granta, which received the numerical index 2190, is a popular car of the VAZ concern. Russian drivers immediately liked it, since at a very reasonable price it was characterized by a European appearance, decent electronic equipment, interior comfort and reliability.

Many buyers are now looking for Grants on the secondary market, intending to save money. Indeed, the reliability of the car is such that this approach is quite acceptable without compromising quality.

The main point is a careful approach to selection, studying all the parts that are most susceptible to wear and tear and the effects of time. One of these parts is the timing belt, the replacement of which we will talk about in this article.

Replacing the timing belt on an 8 valve engine

On the question of motors

Grants are equipped with five power plants. Two of them are equipped with 8 valves, 3 - 16. We will consider 16-valve engines as the most technologically advanced, powerful and in demand.

The leader in popularity is the VAZ 21126 modification, which is a redesigned and improved version of the unit under the symbol 21124.

Other 16-valve engines have indexes 21127 and 21126-77 (sports version). All of them deserve a lot of flattering reviews in terms of reliability and power, but a common disadvantage is the inevitable deformation of the valves when the timing belt breaks, which is fraught with a major restoration that requires huge expenses.

That is why it is extremely important for the owner to detect signs of imminent belt breakage in time and replace it with a new part.

Timing belt malfunctions on Grant and methods of elimination

Failures of the distribution device in advanced cases can lead to failure of the power plant. This can be avoided if you inspect all gas distribution elements in a timely manner and correct defects and breakdowns in a timely manner.

Diagnosing timing belt faults is a complex procedure. Signs may also indicate other components and assemblies. To accurately determine the cause of the failure, it is necessary to dismantle the cylinder head. In a private garage, this procedure is quite labor-intensive, and you also need to have special skills and equipment.

Inspection and signs of wear

The manufacturer recommends carrying out a visual inspection of the belt every 20 thousand kilometers, despite the fact that the declared service life of the original part is 75 thousand kilometers.

The belt is inspected on a cold engine, for which the cover of the gas distribution mechanism is first dismantled. If the glass washer fluid reservoir gets in the way during inspection, it is also better to remove it.

Both the tank and the lid are secured with simple bolts, so there will be no problems with dismantling.

To accurately determine the condition of the belt, you must also remove the right front wheel and the splash guard.

Using the 17 head, the crankshaft rotates to the right; you need to hold on to the powerful bolt that secures the drive pulley of the auxiliary elements.

Signs indicating the need for urgent replacement are as follows:

material delamination;
formation of longitudinal and transverse ruptures, cracks, convex areas;
fractures in the area of the teeth;
traces of soot and melting of the material on the back side of the belt;
tousled material in the end area.

Please note that the reason for replacement is the presence of even one sign.

We would like to separately mention the presence of oil stains on the part. Even if it looks normal, it is better to change it, since oil destroys the material.

How to determine that a break may soon occur

Urgent replacement of the timing belt for a Granta car of 8 and 16 cl. may be necessary if the following phenomena occur:

Decrease in vehicle power. A poorly tensioned or worn drive can make the engine difficult to start and reduce power output.
Incomprehensible noises from the timing belt on the Grant, emanating from the engine compartment. Clunking, ticking or strange rustling noises often indicate that the Granta timing belt is damaged and rubbing against the casing or other parts under the hood
Visible damage. The part may have abrasions, cracks and “shaggy” areas that are visible to the naked eye.

Necessary tool

It is most convenient to work in a garage or on a flat concrete surface. You will need a jack, boots to prevent the vehicle from rolling away, wrenches and sockets, including Torx wrenches.

You immediately need to mentally prepare for the fact that you will have to work in very cramped conditions, and it is better to wear protective gloves on your hands.

If we talk about the new set, the originals are produced by the rubber products plant in the city of Balakovo. You can also find good reviews about analogues produced by European partners.

It’s not worth buying Chinese belts, their service life is much inferior to the original, and their strength can fail at the most inopportune moment.

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.

Features of the replacement process

The main difference between engines with 16 valves and 8-valve solutions is a pair of camshafts. An auxiliary roller is also used to provide better belt drive tension.

First of all, the contacts are removed from the battery. If the machine is equipped with auxiliary mechanisms and devices, such as power steering or air conditioning, their drive belts first swing out, making it difficult to access the main timing belt. Removing them is very simple, you just need to loosen the tension device.

The timing mechanism drive has a polymer casing that protects it from external loads. This casing is removed with a T-30 type key, which can easily unscrew all fasteners.

Removal of the lower casing is hampered by the tensioner of the auxiliary drive belt, which must be lifted up. After this, the drive mechanism will be open.

When access to the belt is open, you need to clearly set the position of the timing drive in accordance with the marks. If this step is ignored, the valves will be deformed.

Marks on the camshafts of a 16 valve engine

To do everything clearly, the position of the drive must be fixed with a special lock. The part is inexpensive, but eliminates a lot of problems.

When the timing belt is loosened, the shafts may diverge.

The next stage is to remove the pulley from the engine crankshaft. The instructions look like this:

The right side of the car is raised slightly on a jack, the body is fixed on a stand, and the wheel is removed.
The assistant sets the gearbox to fifth speed and presses the brake pedal.
Using a 17 socket, the pulley is removed.

All of the above steps help to easily remove the belt. If, after removing the belt, damage is found on the rollers, they should also be replaced.

After installing a new belt, the steps are repeated in reverse order.

When to change the belt

The factory technical documentation states that the timing belt needs to be changed when the mileage reaches 75 thousand km. For various reasons, this can happen much earlier, so it is recommended to inspect the belt drive and check its tension during the next maintenance.

The indicated service life can be greatly underestimated if technical fluids or engine oil enter the working area of the drive. The wear of the teeth of the camshaft pulleys and crankshaft also reduces the service life.

What's the result?

On the dashboard of many modern cars, if the marks are set incorrectly, a “check” will be displayed when the engine starts. This is another sign that the work was carried out incorrectly and further operation of the car is undesirable. Skipping the belt by one “tooth” can result in unpleasant consequences. Even a novice driver can set the markers correctly, but you need to have enough free time and patience.

Hello everyone, I've been struggling with this sound for 5-6 months

Aposlya, I bought a roller, prepared for the replacement for a long time and tediously, and it was this morning))))) I started changing it, unscrewed the roller, the belt loosened and slipped by 1 tooth... bastard! I’ve already assembled everything, I’m trying the car, but it doesn’t drive, as if the handbrake is on... I take it apart again, I did it, but it won’t start at all ((((((((((((whoops, the ignition is completely off and the marks are gone... A couple of minutes later - (I went to eat))), I did everything, set the marks and the ignition was set, everything was in chocolate... spent 3 hours on everything)))))

if you do not have a carburetor, then you should start by removing the air filter housing

Now there is much more space to work

remove the alternator belt (and air conditioner, if equipped)

A timing belt is a relatively simple solution for driving timing gear and other equipment compared to a timing chain. In this case, the specified belt serves less than the chain, that is, it needs periodic replacement. Most drivers know that when replacing a timing belt, the drive pulleys are marked, which is necessary for precise synchronization of the operation of the engine and the gas distribution mechanism.

At the same time, not everyone fully knows how to correctly set the timing belt when replacing it themselves and why it is so important. Let us immediately note that if the timing belt is not aligned with the marks, then a failure of the valve timing occurs. As a result, the engine may not start after such a replacement, it will operate unstably, or even the internal combustion engine may break down. In this article we will talk about what are the symptoms of an incorrectly aligned timing belt, as well as how to align the timing belt with or without marks.

Which cars are equipped with ICE 21127?

Immediately after development, engine 21127 is recommended to be installed on cars manufactured by AvtoVAZ:

Lada Granta - since 2013, Lux and Norma configurations;
Lada Kalina-2 - since 2013, only with a manual transmission, mainly on sedans and hatchbacks;
Lada Priora - since 2013, Luxury equipment.

Lada Priora Luxe configuration
In principle, the engine’s sufficiently high performance characteristics made it possible to install it on the Lada Largus, Vesta and X-Ray. However, by the time of their serial production, the ICE 21127 had been upgraded to the next version 21129 with a control unit that complies with Euro-5 standards, so the plant management limited itself to the indicated modifications, leaving the volumes the same.
