K4M - 16-valve (16V) injection engine with a volume of 1.6 liters, first released in 1999. It is a logical continuation of the K7M engine line, and differs from the latter in its updated cylinder head: the latter has separate camshafts for the intake and exhaust valves. In addition, hydraulic compensators were added to the design of the gas distribution mechanism, which made the engine, in comparison with its predecessors, less noisy.
Main characteristics of the K4M engine:
The declared resource for the K4M engine is up to 500 thousand km.
What could the code be?
Different manufacturers specify a different number of letters and numbers in engine codes, which makes them completely unique. Domestic manufacturers indicate a code mainly of 6-7 digits.
On foreign cars, the individual code can even consist of 18 characters. The full code was previously indicated in the PTS, so it is important that it completely matches the one applied to the engine.

If the engine has been reinstalled, it is recommended to carry supporting documents on all trips.
What to do if the engine is dirty and the license plates are not visible
Those who do not take care of their car may encounter a problem when the markings on the engine are not visible. It is not necessary to immediately send the car to a car wash; it is enough to wash the device with your own hands. For small dirt deposits, you can wash it with a damp cloth soaked in detergent. If the unit is very dirty, you will need sandpaper. Although it’s better not to let it come to that. After washing, the number can be easily seen. If the dirt is not washed off, you cannot do without the help of a car wash.
Short review
On the eve of the spring of 2012, AvtoVAZ released a high-capacity station wagon - Lada Largus. This car is a joint project of the Tolyatti giant AvtoVAZ plant and the French corporation Renault-Nissan Alliance - and, I must say, a very successful one.
To produce the new model, AvtoVAZ workshops were equipped with the latest equipment, and a separate wide full-cycle production base was created. This allowed the use of modern technologies and innovative car assembly lines. As a result, following the pre-production batch of snow-white cars that were not intended for sale, Lada Largus models entered mass production, passed design testing and were available to buyers.
As previously expected by experts, the technical characteristics of the Lada Largus correspond to the status of this, first of all, high-class family car. Key advantages of the new product: spaciousness and reliability, confirmed by a test drive. In general, there are three modifications of the car: and a cargo van.
AvtoVAZ management has already stated that the Lada Largus will not be sold abroad. Basically, the car - which, we note, is maximally adapted to Russian operating conditions - will be sold only in Russia. It will be possible to buy a car through the dealer network of JSC AVTOVAZ, and you can also place an order for the purchase of a car via the Internet.
Production volumes
In February 2012, it is planned to produce more than 600 cars, and further on the rise - in total, about 30,000 new Lada Largus cars will roll off the assembly line in 2012.
As for prices, due to the low cost of car production, it will range from 340 to 420 thousand rubles, depending on the configuration.
Let us remind you that the Lada R90 debuted at the Moscow Motor Show in 2010. The high transformability of the seven-seater cabin allows for a large volume for transporting large and long cargo. In Europe, this car is produced under the Renault brand and is called Logan RF90. The Russian version is adapted to climatic and road conditions.
Device and characteristics
The engine marked K4M is a high-tech power unit with high performance. The first production of the power unit began back in 1999. The motor design is quite simple and understandable. The only difference from its younger brother K7M is that there are two camshafts in the cylinder head.
Also, the engine is much quieter because hydraulic compensators are installed. The engine is equipped with sixteen valves, which increases power characteristics and slightly reduces fuel consumption. The average engine life is 350,000 - 400,000 km.

Vehicle registration details
At the bottom of the front passenger door pillar there is a manufacturer's plate that contains information about the vehicle.
The designations at the bottom of the plate are deciphered as follows:
: 1 – manufacturing plant; 2 – vehicle type approval number; 3 – vehicle identification number (VIN); 4 – permissible maximum vehicle weight; 5 – permissible maximum weight of a vehicle with a trailer equipped with brakes; 6 – maximum permissible load on the front axle, kg; 7 – maximum permissible load on the rear axle, kg
The vehicle identification number (VIN) is located on the body cross member under the front passenger seat. The model and engine number are printed on the boss of the front wall of the cylinder block, next to the oil pressure indicator sensor.
Location of engine number 1.6 (16V)
For clarity, the location of the engine number 1.6 (16V) is shown on the dismantled engine
Location of engine number 1.6 (8V)
For clarity, the location of engine number 1.6 (8V) is shown with the exhaust manifold heat shield removed
On the first Largus, the engine was still Spanish, then these engines began to be assembled in Russia, and a long time ago, after buying the second Largus, I was 100% sure that the engine was our assembly, but now I decided to check and was very surprised, the engine is Spanish! Number starts with D
the letter in the engine number is the manufacturer's code. D
— Valladolid, Spain,
U
— Dacia, Romania,
R
— Tolyatti.
C
- Cleon, France.
R
- Turkey
An addition to the basic information for the K4M K is the engine range, which determines the crankcase material, the type of cylinder liners, the number of cylinders and crankshaft supports. 4 - head type, valve location. M is the approximate working volume. (in our case from 1576 to 1650) Next is the suffix. These are the letters/numbers after the engine type. The first digit (if 6, 7, or af - then the engine was manufactured at Renault factories. The last digit - even - means that the engine is designed for mechanics. - not even - for automatic transmission. If the suffix contains the letter S (for example S 0000) - this indicates that the engine has been overhauled or assembled from parts of other engines.
Next, the cooling system and drive belts. Recommended product for the TOTAL GLACEOL RX cooling system. Not available for free sale. TOTAL GLACELF AUTO SUPRA is produced as a direct analogue for the wide market. Thermostat opening temperature = 83 degrees. 2-speed fan. 1 speed = turns on at 99 degrees, turns off at 96 degrees. Speed 2 = turns on at 102 degrees, turns off at 99 degrees. Constant operation of the fan indicates that the temperature sensor is faulty and the fans have gone into emergency mode.
OIL LEVEL IS NOT LOWER OR ABOVE THE REQUIRED LEVEL!
Excessive amount of oil in the engine leads to an increase in the amount of crankcase gases - this leads to coking of the throttle valve in the engine intake tract.
Where is the VIN number of the Lada Largus?
Many new owners of a domestic station wagon are wondering where the Lada Largus wine is located? Previously, on all VAZ cars, the VIN code was located in the luggage compartment and under the hood. But, LADA Largus is a joint brainchild of the Renault-Nissan-AvtoVAZ alliance, so the VIN number was moved from its usual places.
1. The knocked-out VIN of the Lada Largus is located under the front passenger seat on the transverse floor reinforcement. It’s easy to see – just move the passenger seat as far back as possible. After which you will be able to see a cutout in the carpet through which you can read the VIN code.
2. The VIN number of the Lada Largus is also printed on a duplicate plate on the right central passenger pillar.
Where is the Lada Largus engine number?
If everything is quite simple with the Vin number of the Lada Largus, then you will have to tinker with the engine number. The fact is that the Lada Largus engine number is located on the block in the front part of the engine compartment. It is located under the exhaust manifold heat shield.
In order to see the engine number of the Lada Largus, you will have to either remove the heat shield or use a special mirror.
Tuning the K4M 16V engine
Car owners perform tuning of the K4M engine. Thus, it is possible to increase power, dynamics and improve technical characteristics. To upgrade, perform the following steps:
- Flashing the electronic control unit. The Largus K4M engine, and other car models, is electronically controlled. ECU firmware allows you to improve the technical characteristics of the engine and increase its power. The programming of the unit must be carried out by professional workers. Violation of this rule may lead to failure of the power unit;
- Some car owners equip the engine with a compressor. This allows you to improve dynamic performance;
- It is possible to install a turbine on the K4M engine. This increases maximum power and improves engine dynamics.
ATTENTION: Installing a turbine will reduce engine life. The K4M engine, which has a service life of about 400,000 km, will operate under high load. This will lead to rapid wear of components.
From the above it follows that the engine of Renault and Lada Largus K4m cars is a four-cylinder gasoline power unit with a 16-valve gas distribution mechanism. The motor is economical and unpretentious to operating conditions.
Stealing a Lada Largus is a pretty funny idea, so knowledge of the location of forensic markings is only necessary in order not to make a mistake when checking the traffic police registration numbers.
The main VIN number is located where air conditioning condensation sometimes reaches - a strip under the front passenger seat:
The duplicate sticker is located on the right central pillar, you should see it when you open the door in search of the main VIN. If it is not there or it is quite damaged, which often happens with Largus, then problems are likely during reconciliation:
Before buying a used car, it is very advisable to check the VIN registered in the ECU units:
Over the years of Renault's existence, the concern's products have been equipped with different engines. Since 1999, the popular models Logan, Sandero and others have been equipped with the K4M engine, and some examples of the domestic Lada Largus model are also equipped with it.
Service
With normal and timely maintenance, the Largus 16 cl. 1.6 liters can last quite a long time, and to be more precise, up to 500,000 km. According to the manufacturer's standards, as well as service manuals, the engine must undergo scheduled maintenance every 10,000 - 12,000 km, and it does not matter what fuel the power unit is operated on.
Let's consider what operations are provided for during scheduled maintenance of the Largus engine, which has a 16 valve mechanism:
Body: dimensions, features
This is a standard passenger station wagon, available in 2 versions: 5- and 7-seater. The body dimensions of the Lada Largus station wagon are as follows (in mm):
With such dimensions, Largus has a simple exterior, essentially repeating the features of the 7-seater Dacia Logan MCV station wagon. It meets the basic ideas of a comfortable, budget car for the whole family - its design is simple, laconic, and devoid of pretentiousness. The control dimensions of the car basically repeat the dimensions of the first generation Renault Logan.
VIN code
1. The identification number (VIN) is stamped on the floor under the front passenger seat on the right side. To inspect the room, a valve has been cut out of the carpet. The VIN code is also duplicated on the wall between the engine compartment and the engine.
Depending on the configuration of the Lada XRAY, there may be a glove box under the passenger seat. In this case, to access the number, you must fully extend the movable part of the glove box by pulling the stops outward on both sides.
2. The marking (nameplate) is located on the right pillar, below, near the threshold.
It indicates the model, car number, engine model, weight data, number for spare parts, design options, and configurations. Explanation:
