Diagnostics and replacement of the timing belt on an 8-valve engine

Before replacing it yourself, do not forget to carry out comprehensive diagnostics in order to study the general technical condition of the car, identify breakdowns and other malfunctions. To analyze mechanisms without preliminary diagnostics is the height of unprofessionalism.

Diagnostic stages:

• We jack up the right side of the car and hang it at a sufficient height so that the wheel rotates freely by hand;
• We activate fifth gear;
• In the engine compartment, remove the plastic casing and turn the drive belt. We assess its condition and decide whether replacement is necessary.

After the final decision on replacement has been made, we begin dismantling. We first prepare a set of automotive tools, rags, a new belt, and a roller bearing. Bearing replacement is required. The service life is approximately equal to that of the drive belt.

Belt selection

Now let’s look at which is better to choose a timing belt for the VAZ 2114 with eight or sixteen valves.
It is not easy to buy a good product that can be installed and tightened on the timing gear drive. After all, the strap you need must be of high quality.

Today, consumers are offered several worthy products from manufacturers:

1. ContiTech Antriebssysteme GmbH. There is a sticker with a QR code on the original packaging of the belt. In the kit you can find a label indicating the date of change, mileage of the vehicle and information about the components that were changed at one time. When carrying out repairs, installation, belt tensioning, and also replacing rollers, you can indicate all the information on paper and, if necessary, see when and what exactly was changed last time. On the strap itself you will see the brand designation and batch number.
2. Gates 5670XS. The packaging of the original product contains a QR code, as well as a hologram designed to protect against counterfeit goods. A serial number is applied to the outside of the strap. The product comes with a sticker on which you can indicate the belt number and the date when it was replaced.
3. Trialli GD 790. An Italian-made product is sold on our market in the form of a repair kit with a tensioner pulley. The product is packaged in a cardboard box with a plastic insert inside. This belt kit also includes a sticker with the vehicle's mileage and the date the part was changed. Here you will see the warranty card. The manufacturer took care and included detailed replacement instructions in the kit.

The carMA channel has published a video that will allow you to accurately understand the timing of replacing the product.

Timing belt replacement interval

The manufacturer indicates an interval of 60,000 km, after which the Granta liftback timing belt needs to be replaced. At the same time, every 15,000 km, it is necessary to carry out diagnostics of the drive belt in order to detect defects, delamination, and possible damage.

If the car is operated in rough, dusty terrain, under systematic loads, reduce the replacement interval by a third. Obviously, this is just a recommendation and not a commitment. In order to increase the service life, it is still better to listen to the advice of professionals.

Purpose of the timing belt

Ensuring synchronized operation of the power unit mechanisms for cyclic supply of the fuel mixture into the combustion chamber with subsequent ignition.

Violation of the tact, operation, and cyclicity leads to instability in the supply of a lean / rich mixture. As a result, the engine does not operate at full power, and detonation can be seen at idle. The previous article () discussed in detail the purpose of the timing system.

Characteristics of Lada Granta timing belt

The Lada Granta gas distribution mechanism is driven by a belt. This type of device has been familiar to car enthusiasts for a long time. After all, the timing belt design migrated from the VAZ 2108 engine, which became the basis for all subsequent modifications of VAZ power plants. The Grant is equipped with two types of engines: an 8-valve engine and a 16-valve engine. The gas distribution system of the 16-valve power unit has a complex structure and increased dimensions compared to the 8-valve one. Accordingly, replacing the Granta timing belt becomes more complicated.

The main feature of the 16-valve device is the presence of two camshafts operating synchronously, in parallel with the crankshaft. The structure is located in the cylinder head. All three shafts are synchronized via a toothed belt. The main disadvantage of a timing belt drive is the unreliability of the belt itself. When it breaks or jumps, the valves meet the pistons and bend. The structure of the 16-valve timing belt is clearly shown in the photo.

2. Lid.
3. Intake camshaft pulley.
4. Phase disk (sensor).
5. TDC mark on the camshaft.
6. Exhaust camshaft pulley.
7. Support roller.
8. Tensioner roller.
9. Drive belt.
10. Pump pulley (coolant pump).
11. Installation mark on the oil pump.
12. Crankshaft alignment mark.
13. Crankshaft pulley.

You can change the timing belt kit yourself. The main thing is to know about the presence and correct placement of installation marks. By the way, most foreign cars do not have such marks, so in this case VAZ cars have the advantage.

The eight-valve timing drive of the Lada Granta, compared to previous modifications of the car, looks simpler. The scheme is simple, because there is no idler roller and there is only one camshaft. The 8-valve timing device can be seen clearly in the photo.

If you have doubts about your own abilities, you should not try to replace the timing belt yourself, as you can cause even more damage. In addition, in a car service center such a procedure, performed on an 8-valve engine, is inexpensive. But in the case of a 16-valve engine, the price tag is usually much higher.

Replacing the timing belt on a 16-valve Granta engine

Access to the gas distribution device drive is covered with a plastic casing. To remove the cover, you need to unscrew five screws with a 5mm hex key. Pay special attention to the location of these screws. In the photo, number 1 shows the fastening screws of the top cover, and number 2 shows the fastening screws of the bottom cover. After unscrewing the five screws, the top cover must be lifted and removed from the engine.

If the car has a manual transmission, you need to engage fifth gear, lift the right front wheel and turn it clockwise. At the same time, it is necessary to inspect the belt for cracks, abrasions, delamination, etc. If the car is equipped with an automatic transmission, you need to remove the right front wheel and the boot (protective shield) on the right. Using a 17mm head, rotate the bolt securing the drive pulley for additional equipment (air conditioning, generator) and inspect the belt. If various defects and damage to the belt are diagnosed, it must be urgently replaced. Replacement will also be required if oil leaks, a malfunction of the water pump or tensioner roller are detected.

On a 16-valve engine, a broken belt drive will lead to a discrepancy in the angular position of the crankshaft and camshafts. As a result, the piston group will come into contact with the valves. As a result, repair work will be required.

The popular VAZ 21116 (11186) engine is also installed on the Lada Granta. This engine doesn’t have enough stars in the sky, but it’s nice because you can easily carry out its maintenance and repairs with your own hands in a garage. He has several problems, however, they can be solved with careful and timely care. Replacing the timing belt on an 8-valve Granta with your own hands will not cause any problems if you change the belt according to technology, not forgetting about choosing a high-quality belt.

There are quite a few tales about what will happen if the timing belt breaks while the engine is running. Unfortunately, regarding the VAZ 21116 engine, most of them are not far from the truth. For this engine, a broken camshaft drive belt is more than critical. The meeting between pistons and valves, as a rule, does not end very well: bent valves, torn connecting rods, punctured cylinder blocks and torn pistons - all this can really happen if the timing belt is not replaced on time.

Bent valves in the block head

In order for the engine to serve for a long time and reliably, it is simply enough to inspect the drive belt once every 10-15 thousand kilometers.

camshaft and if alarming symptoms are detected, do not be lazy and change it immediately. Signs that the strap is asking to be retired are clear even to a teapot:

1. Cracks, cuts, nicks, and other mechanical damage are clearly visible on the surface of the belt.
2. The teeth may be damaged or even cut off.
3. The belt has traces of contact with operating fluids - oils, gasoline, antifreeze, brake fluid. But before changing the belt, you need to find and eliminate the cause of fluid leakage.
4. Delamination of rubber material.
5. Belt stretch.

Therefore, replacing the belt under normal conditions, when all other units and systems work well and do not cause complaints, is carried out every 40-50 thousand km

, and check the condition of the belt at least
once every 10-15 thousand km
. In this case, the VAZ 21116 engine will cover its service life of 180-200 thousand before overhaul without any problems.

The same applies to engines with an 8-valve head VAZ 11186, which are absolutely identical to the VAZ 21116, but have a cylinder-piston group from Federal Mogul.

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

Stages of work

The next important stage is the correct tension of the timing belt drive of the Lada Granta with 16 cl and 8 cl units.

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.

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.

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:

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

Please be aware that reusing the alternator belt is a last resort. It would be better to buy a new part.

Signs of belt wear

As we have already noted, it is necessary to regularly monitor the condition of the timing belt. This will allow you to notice its damage even before it completely fails, damaging engine parts. The first sign will be significant wear and tear on the material. If this is the case, then you run the risk of slipping or breaking if there is a significant load on the car, as well as with high air humidity. It follows that wear occurs, as a rule, when the position of the tension roller and pulley deviates, as well as when the bearing temperature is high or its unsatisfactory operation. You can notice this by the fact that the material will be worn out and fabric debris will stick out from it. The third sign suggests the presence of cracks or peeling. The more such damage, the higher the chance that the belt will break very soon. Problems are also typical for situations where the back surface of the belt has a low elasticity index and significant hardness. This will also give away the characteristic shine of the belt. This will not allow it to make good contact with the pulley. During use, the belt may lengthen. If this parameter has become too large, then it is worth replacing the belt with a new one, especially since its elastic abilities will be significantly reduced. And, of course, if the belt position deviates from the specified one, this will indicate a situation where the tension roller components may fail.

The timing belt was removed for inspection and still works, but the owner decided to replace it

In this case the belt is still in good condition

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.

According to the regulations, the timing belt needs to be replaced every 75,000 km. The advice applies to VAZ-11183, 11186 and 21116 engines and are installed in Grant cars. Let's consider replacement steps.
