Engine 11186 is the minimum power unit in terms of power. which is standard equipment on Lada Granta and Lada Kalina cars. The VAZ 11186 engine is standardly coupled with a manual transmission. The start of serial production of the engine is in 2011. Environmental standards Euro-4.
The engine is structurally designed as an in-line gasoline four with a volume of 1586 cubic centimeters. Maximum power of 87 hp. reaches at 5100 rpm. Maximum torque of 140 Nm is produced at 3800 rpm.
It is the second iteration of the modification of the classic front-wheel drive engine 21083. The predecessor is the VAZ 21114 engine with a volume of 1.6 liters. The engine has an additional index VAZ 21116. The main difference is the use of a piston system on 11186, manufactured by AvtoVAZ OJSC, and not by Federal Mogul.
The declared engine life is 200,000 km. The actual mileage before the first major overhaul is not recorded. The Russian manufacturer does not have the practice of monitoring typed cars by mileage. According to existing unverified reviews, the actual mileage exceeds the service life of 21,114, but does not reach the declared one.
SOHC engine design diagram. One camshaft located at the top of the engine. Accordingly, we have 8 valves, 2 for each cylinder. The camshaft is driven by a belt. During operation, the belt does not require replacement, since the declared life of the belt coincides with the life of the engine. The belt tension is automatic and is designed by design.
Fuel supply system is injection with electronic control. Spark plugs are standard A17DVRM. The spark is supplied by the ignition unit according to the 2-2 scheme, i.e. spark is supplied to two cylinders at the same time
Acquired deficiencies
The crankshaft of the 1.6 engine is quite modern, it is fully counterbalanced, that is, on the extension of each shaft cheek there is a counterweight (eight in total). Imported motors often have only four counterweights. They save.
“Weight loss” is visible everywhere. The thin rod of the connecting rod merges into a smaller lower head. The piston is lightened to the limit. The area where the piston rings are located and two small “tongues” are left, replacing the previous full skirt.

A short piston skirt is in the spirit of modern automotive engineering, but this solution does not have the best effect on engine life. Not only is the piston bearing surface small, but also shifting (lateral vibrations) is more possible than with older, tall pistons.
The connecting rods of the current modification of the engine have become noticeably thinner compared to the old ones, with the index 2108. A high-tech break-off connecting rod cover has also appeared, but the width of the connecting rod bearing has been significantly reduced. Yes, the mass of the connecting rod was reduced a little in this way. But this definitely increased the load on the bearing. At the same time, the width of the neck on the shaft remained the same. It would be quite possible to install a connecting rod with a “wide” lower head.
You can clearly see how narrower the lower connecting rod head is than the crankshaft journal.

Maintenance
In accordance with the manufacturer's regulations, engine 11186 must be serviced in the following order:
| Maintenance object | Time (year) or mileage (1000 km), whichever comes first |
| Timing belt | 3/50 |
| battery | 1/20 |
| Valve clearances | 2/20 |
| Crankcase ventilation | 2/20 |
| Belts that drive attachments | 2/20 |
| Fuel line and tank cap | 2/40 |
| Motor oil | 1/10 |
| Oil filter) | 1/10 |
| Air filter) | 1 – 2/40 |
| Fuel filter) | 4/40 |
| Heating/Cooling Fittings and Hoses | 2/40 |
| coolant | 2/40 |
| Oxygen sensor | 100 |
| Spark plug | 1 – 2/20 |
| Exhaust manifold | 1 |
This is exactly the frequency of maintenance that the ICE 11186 device is designed for.
Timing drive
The latest generation VAZ engine has become “non-plug-in” (that is, if the timing belt breaks, the pistons do not bend the valves), which, on the one hand, pleases, but on the other, brings sadness. For some reason, not a single automaker in the world cares about a “non-plug-in” design. It turns out that VAZ’s timing drive is so unreliable that the manufacturer had to insure itself in this way by providing recesses for the valves on the pistons.
Maintenance frequency and cost
The regulated maintenance interval is 15,000 km or 1 year, whichever comes first. The calendar maintenance period is set based on the criteria for maintaining the lubricating properties of the engine oil, taking into account its possible oxidation. The air supply system filter element is changed every 30,000 km, as are the spark plugs.
The first valve adjustment is performed after running in the engine during TO-0, then at 15,000 km during TO-1 and then at 30,000 km intervals. At TO-5 (75,000 km), the oxygen sensor is changed, and the generator drive belt is changed at 90,000 km.
The average cost of maintenance, taking into account checking other vehicle systems without the cost of consumables, does not exceed 5,000 rubles.
Competitive or not?
Technical characteristics of the VAZ 1.6 engine
| Engine model | 11186 | 21126 | 21127 |
| Valve mechanism | 8 valves | 16 valves | |
| Cylinder diameter × piston stroke, mm | 82,0 × 75,6 | ||
| Working volume, cm3 | 1596 | ||
| Rated power, hp at engine crankshaft speed, min-1 | 87 5100 | 98 5600 | 106 5800 |
| Maximum torque, N∙m at engine speed, min-1 | 140 3800 | 145 4000 | 148 4200 |
The performance of the domestic engine with a displacement of 1.6 liters is very far from modern ones. Judge for yourself: most foreign engines with a displacement of 1.6 liters have a power of more than 120 hp. And this indicates that the design of the VAZ engine is outdated. Even the controlled length of the intake pipe used on the 106-horsepower version of the engine will not replace variable valve timing systems.
But on foreign cars it is also implemented on the exhaust camshaft (in addition to the intake). In general, if we recall the famous Honda engines of the nineties, they produced about 160 hp due to valve control and high speeds. or more with a working volume of 1.6 liters. And these were naturally aspirated engines for mass-produced cars.
The alliance partner Renault has a similar line of power units. Having similar technical characteristics, French engines, however, are more advanced from a design point of view. And in terms of reliability, they outperform VAZ engines.

Now let's look at the design features of the VAZ engine.
Problems with the motor 11189
Despite all the advantages, with long-term operation of the 11189 engine, the following breakdowns may occur in Lada:
- Malfunctions in the operation of the indicators of the electronic throttle drive E-gas, which in most cases lead to the appearance of floating idle speed.
- Burnout of valves and malfunction of the ignition coil, which causes the engine to trip (1-2 cylinders of the engine stop working completely).
- Damage to the mass air flow sensor is considered the most common reason that the “iron horse” stalls while driving. A breakdown can lead to an accident.
- Overheating occurs, most often caused by an unreliable thermostat.
- Knocks and noises may be heard from under the hood. They appear mainly due to incorrectly set valve clearances.
- According to reviews, the 11189 engines have significantly reduced oil leaks compared to earlier engine models, but this problem has not yet been completely eliminated.
- Due to a design miscalculation, the occurrence of jamming of the water pump becomes inevitable for the engine. Experts recommend monitoring her condition with special attention.
Why does the Granta 8 valve bend the valve?
The breakdown procedure itself is also equally important to study. Having understood which areas are most susceptible to damage, the owner will be able to pay more attention to them or seek help from specialists.
After diagnostics, our technicians will perform a full service and help you avoid numerous causes of timing belt failure: jamming of the pump, rollers, camshaft or crankshaft. The process of valve damage itself occurs according to the following scheme:
1. The timing belt breaks.
2. The camshaft stops.
3. The crankshaft continues to rotate (the flywheel transmits rotation).
4. The pistons hit the open valves when the timing belt breaks.
Thus, the valves become bent, and in the future they will need to be completely replaced. You can also find out whether the valves of the Lada Granta 8 valve are bent from specialists working at the service station.
After all, a breakdown does not necessarily affect every owner of a domestic car. Damage occurs in exceptional cases when the motorist does not devote enough time to servicing the car. Therefore, the root cause is insufficiently conscientious operation.
Many craftsmen recommend that immediately after purchasing a Granta, you have it checked at a service station, since even small nicks on the shafts can lead to a rupture of the timing belt.
In some cases, changing the belt to a stronger one helps: the factory component may not meet the required load and operating conditions. The tension force must fully comply with the stated recommendations of the manufacturers. Therefore, self-regulation can only worsen the situation.
You should also contact a specialist if primary signs appear that may indicate a subsequent belt rupture. It could be minor noise from the timing drive. It is this that will indicate possible wear or partial wedge of the rollers or pump.
All these factors are decisive and can lead to the need for expensive repairs, and in extreme cases, to calling a tow truck if the driver was outside the city at the time of the rupture. The owner of the Grant needs to take into account all the considered nuances and solve the slightest problems immediately after they arise.
Experts consider the VAZ 11186 engine as a modernization of the 21114 engine, a secondary modification of the 21083, or an improvement in the characteristics of the 11183 internal combustion engine. The first option is considered more correct, since the design of 11186 and 21114 is absolutely identical, with the exception of the pistons. The 11186 engine is equipped with AvtoVAZ products, and the previous version of the internal combustion engine was equipped with pistons from the manufacturer Federal Mogul (USA), which developed it under a contract with the Volzhsky Automobile Plant.
The difference between motor 11189 and motor 11186
The main distinguishing feature of the earlier engine model is the 39% lighter connecting rod and piston group. The use of tandem parts made it possible to significantly reduce engine noise and vibration while the vehicle was moving. The new anti-friction inserts in the piston design and thinner rings have reduced the finishing process to a minimum. However, the new model abandoned the holes on the bottom.
Reviews from car owners
All oils presented in the review received positive feedback from Lada Granta owners. Car enthusiasts note their high cleaning and protective properties. Most products are rated as economical. When using them, it is rarely necessary to add oil, and the mixture remaining after replacement is enough for the entire operating interval.
Many drivers note that the engine runs much quieter with synthetic formulations than with semi-synthetic oils. Do you agree with this opinion?

Malfunctions: causes, elimination
Like all internal combustion engines with mechanical adjustment of valve clearances, the 11186 engine requires periodic adjustment of this characteristic. In addition, during operation, characteristic “diseases” of this particular version of the power drive were identified:
| Bend valves | broken timing belt | periodic wear monitoring |
| Ignition system interruptions | failure of the corresponding block | replacing the ignition module |
| Increased oil consumption | wear of the main bearings, stuck piston rings | replacement of consumables |
| Knock | wear of pistons, bearings | replacement of parts |
When repairing piston and crankshaft engines, it is recommended to use original components from the AvtoVAZ manufacturer. Because only he uses special technologies for strengthening structural materials. From third-party companies, the metal may be “raw”; the resource of such consumables cannot be analyzed.
The ignition module cannot be repaired
Services for selecting motor oils
A car owner who is not sure which oil should be used can use the selection service. Similar services are offered on the website of any manufacturer or in online stores specializing in the sale of fuels and lubricants.
The following are used as initial data:
An alternative selection option is to search for suitable compositions based on the required quality indicator and desired viscosity.
Examples of trustworthy resources:
Installation of the turbine on the engine
The simplest option for turbocharging 11189 engines is considered to be the use of kits based on the Garrett 17 turbine. Using this kit, it is quite possible to increase the power of the “heart” of the car to 130 hp. With.
Today, there are other methods for installing a turbine, but they require large investments and labor costs. In addition, such engines, when turbocharged, are considered very sensitive to detonation, which as a result leads to a decrease in engine life and the need for expensive repairs in the future.
Increase engine power 11189 to 180 hp. With. it is quite possible by replacing the 8-valve cylinder head with a 16-valve one. After carrying out such actions, you can use any of the above methods to tune the engine.
Lada Granta car: engine life and other characteristics
What are the characteristics of the Lada Granta car, engine life in particular? This question is asked by many fans of the domestic automobile industry. Interest in the car is caused by its positioning as a “people's car”, characterized by budget and capacity, which allows the Grant to be classified as class C. But does the Granta’s power unit meet modern requirements?
What kind of oil to fill in Lada Granta
The manufacturer recommends filling Lada cars with synthetic or semi-synthetic mixtures.
In this case, it is allowed to use 4 types of viscosity:
According to the API quality class, mixtures marked SJ and higher are suitable.
Main selection criteria
When choosing engine oil, the Lada Granta owner must consider:
The brand of the product is secondary. The main requirement is that its parameters comply with the factory recommendations.
In addition, you need to avoid counterfeits and buy only original formulations in specialized stores or branded gas stations.
Factors such as body type, such as a liftback or sedan, as well as the brand of gasoline being poured do not affect the choice of oil.
