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
Modifications applied to the engine
To ensure normal temperature conditions of 95C when using gasoline with an octane rating of at least 95, the cooling system has been modified. Changed to increase the area and flow area of the cooling channels, and increased the volume of antifreeze poured.
Changes were made to the internal channels of the engine head. To ensure increased second consumption of antifreeze, a pump from a 16-valve engine is installed on the engine. In addition, the design of the thermostat has been changed.
In order to reduce fuel consumption and increase engine reliability, major modifications have been made. The engine is equipped with a connecting rod and piston group that is lightened by almost 40% compared to the VAZ-21114 engine. This change not only reduced the weight of the engine itself, but, more importantly, reduced the inertia of the entire system. The design innovation made it possible to increase the declared service life before major repairs.
Externally, the motor also differs from its predecessor. A longer intake tract was installed, which made it possible to achieve a higher torque value and bring the performance of the 8-valve engine closer to the 16-valve engine.
The exhaust manifold has elongated pipes and a more voluminous resonator, which significantly facilitates the engine's breathing at the exhaust, since the aerodynamic resistance of the exhaust tract is reduced.
The generator mounting bracket has been changed to make it possible to adjust the drive belt using an eccentric tensioner roller. This design is also used on VAZ Vesta car engines.
List of car models in which it was installed
Engine 11186 from VAZ was installed on the following vehicle models:
- Datsun mi-Do first generation. This is a five-door hatchback. Produced from 2014 to the present time;
- Dtasun on-Do. This is a restyling of the previous car;
- Lada Granta. Restyling sedan. Produced from 2022 to present time;
- Lada Granta Cross. This is a station wagon. Available from 2022;
- Lada Kalina. Second generation station wagon. It has been produced since 2013 and was completed in 2018;
- Lada Kalina Cross. First generation station wagon. Produced from 2014 to 2022.
Now let's look at the design features of the VAZ engine.
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.
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.
Basic faults
Structurally, it is possible to bend the valves when the timing belt breaks. Using only the original belt avoids this problem. The problem can arise due to poor assembly, which is rare, or when the belt tension system fails. In the event of an emergency, the camshaft and even the crankshaft may be bent.
After performing repairs without replacing the main and connecting rod bearings, the pressure in the oil system may drop and oil consumption may increase. It is not possible to determine whether the valve bends when the belt actually breaks under operating conditions, since there is no open manufacturer data on such a malfunction.
Replacing the timing belt is not regulated by maintenance programs.
Troubleshooting, misfire. Failure of the ignition unit. The malfunction occurs due to a defect in the block itself. The unit cannot be repaired and must be replaced entirely.
Overheat. Associated with contamination of the surface of the cooling radiator. Another reason is a malfunction of the thermostat element, which may become stuck in the open or closed position. The most common problem is that the thermostat element is stuck in the open position, which results in a lower operating temperature of the engine.
Valve knocking. This is normal wear and tear. Eliminated by selecting adjusting washers.
The engine stalls at idle or while driving. There is a problem with the electronic sensors that the motor is equipped with. Basically, the problem is solved by replacing the mass fuel flow sensor (MAF)
Idle speed fluctuates. The reason is a problem with the idle speed sensor or due to the presence of air leaks into the vacuum brake booster (it is necessary to check the pipelines for damage).
High idle speed. This malfunction indicates a break in the crankcase gas suction pipeline.
The most common problems of internal combustion engines 11186
Malfunctions of the VAZ 11186 begin after 60,000 kilometers, if you do not visit the service center at 40 thousand. Knocks may appear in the VAZ engine. They indicate unadjusted valve clearances. If everything is fine with them, then pay attention to the connecting rod and main bearings of the crankshaft. They may need to be replaced.
If the speed in the VAZ engine fluctuates. The problem may lie in a malfunction of the throttle valve. It is necessary to check the functionality of the damper sensors. If they are not working properly, replace them with new ones.
If the thermostat breaks down, the VAZ 11186 engine begins to warm up slowly. When starting, it stalls - problems with the mass air flow sensor. If the mass air flow sensor is not repaired in time, the car may stall while driving somewhere on the highway.
There may be problems with the ignition unit or the standard electronic unit. The latter is unreliable. Therefore, if glitches appear in the control unit, it is better to replace it immediately.

Among the critical breakdowns, experienced mechanics identify problems with the pump and tension roller. If the roller jams, the teeth of the timing belt are cut off. The valve bends in almost every such case. The engine is immediately sent for overhaul. Therefore, it is better to avoid roller wedge and problems with the pump.
Possibilities for engine modification and tuning
As an option to increase engine power, it is possible to carry out chip tuning in order to remove restrictions on the environmental class. The overall percentage of power increase will not exceed 2-5%.
Replacing the camshaft. It is not economically feasible, just like installing a turbocharger. Replacing the camshaft and receiver will remove 100 hp from the engine. If you additionally modify the cylinder head channels, you can gain an additional 20 hp.
To carry out such modifications, it is first necessary to change the engine design from SOHC to DOHC. That is, it is necessary to replace the cylinder head with a 16 valve with two camshafts. Such a replacement will increase the possible power of the 8-valve engine to 120 hp. without significant impact on the overall engine life.
In fact, modification of the engine comes down to converting it into a 16-valve version with the possibility of further refinement and increased power.

Oil change intervals
The car manufacturer indicated in the operating manual the frequency of 15 thousand km. But it is recommended to halve this interval if the car is used only in the city. Driving in stop-start mode due to traffic lights and traffic jams has a much worse effect on the engine than driving evenly along the highway. It also accelerates the depletion of oil and the loss of its properties. Even ester synthetic compounds are not an exception. They need to be updated at the same frequency to keep the engine protected.
What is engine life
Each machine has a device that determines its movement. This power unit is called an engine. In turn, each motor has a certain operating life, during which no intervention in its design is required. In mechanics, this concept has a precise name - engine life.
In other words, the resource is the mileage before the onset of repair work related to the dismantling of the crankshaft of the unit. The limiting state is determined by a drop in engine power, the appearance of uncharacteristic noise during its operation (knocking, creaking, etc.) or an increase in oil and fuel consumption.
In most cases, the condition of the engine is not related to mileage. The main factors influencing the reliability of its operation are operating conditions and workmanship. An engine operated in compliance with the rules can travel hundreds of thousands of kilometers without repair.
The engines installed on the Lada Grant belong to a new generation of power units that are successfully used by domestic models. These are engines 11183 in the standard configuration, 11186/21116 in the standard configuration, and 21116 in the luxury configuration. Each of them has its own characteristics and characteristics, which need to be considered in more detail.
VAZ 11183/21114
The volume of the power plant is 1.6 liters. In fact, it is a development of the old one and a half liter engine. Engineers managed to increase reliability by replacing the materials used to produce some elements and optimizing the design. If we talk about the resource, the manufacturing plant itself set the mark at 150 thousand kilometers. Practice shows that
values of 250-300 thousand are quite achievable if certain recommendations are followed. The main requirement is timely oil changes, effective heat removal will reduce wear on all engine elements. A big plus of the engine is its resistance to timing belt breaks; even in a critical situation, the likelihood of valve bending is minimal.
Choosing engine oil wisely
When choosing an oil, the most important thing is not to make a mistake and select it strictly according to the manufacturer’s specifications. The picture below shows the factory's recommendations (excerpt from the service book).
Engine oil table (first sheet)
Engine oil table (second sheet)
The first thing that catches your eye is the absence of Castrol, ZIC and other famous manufacturers.
Why? They didn't pay for advertising? By the way, for a 16-valve engine, which is not discussed in this article, the instruction manual for the Lada Priora car contains these oils.
By the way, many car owners try to fill in the oil that was filled in from the factory.
Opinion of Grantovodov
What do the owners of this car themselves think?
Opinions were divided. Some still do not trust the domestic manufacturer, while others, on the contrary, are inclined to believe that there is no need to overpay for a foreign brand. Opinions about the choice of oil were divided even among owners of 16-valve engines.
Let us only note that we have never seen Novoil Super oil from BashNeft or TatNeft Synthetic from TatNeft on sale, although we asked at their gas stations in our city.
There should be no problems with purchasing other domestic oils; they are presented in most auto stores and are in demand due to their low cost.

All the problems of its predecessors apply to this unit in full. The engine often suffers from lubricant leaks, tripping, floating speed, sensor glitches and valve burnout. Plus, you can add hydraulic compensators that are very demanding on oil quality.
All technical characteristics of the engine are described on the Motor VAZ portal
The updated engine received an adjustable intake tract with dampers in the receiver channels. Also here, the mass air flow sensor gave way to a combination of absolute pressure and air temperature sensors, thanks to which the frequent problem of floating speed at idle has finally gone away.

Useful tips
The main recommendation of all auto mechanics is to make sure before purchasing that the product you are purchasing is not a counterfeit. To do this, you need to study the protection system developed by the manufacturer. The most commonly used are holograms, lids with complex seals, etc.
Another way to check is physical.
You need to drop the oil onto the newsprint and make sure that it:
An alternative is to place the mixture in the freezer. If after several hours its viscosity has not changed, the oil can be used.
Another recommendation for selecting oil is that you should not radically change the composition. It is best to choose a product of the quality class and manufacturing method that was used before. This primarily applies to cars with high mileage. If the owner has been filling in mineral or semi-synthetic oil with low characteristics for a long time, then replacing it with a synthetic product with detergent additives can worsen engine performance: old deposits will be broken up, and the resulting debris will clog the system.
Additional advice concerns changing the oil after break-in. Experienced car enthusiasts recommend updating the mixture filled at the factory after 2 thousand kilometers.
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.
Synthetic or semi-synthetic
Currently there is a very extensive selection of oils
The manufacturer recommends only semi-synthetics. However, some car owners use synthetic oil, since it makes it easier for the engine to start in severe frost.
Pros of synthetic oil
Even though synthetic oil has better consumer qualities, it is still necessary to carefully monitor engine operation (vibration, speed, operating temperature (by the way, what is the operating temperature of an 8-valve engine?).
