Lada Largus: changing the oil and oil filter in a 16-valve engine

This unit is very important for the efficient operation of the engine, because it performs several tasks at once. Motor oil lubricates the surfaces of the contacting parts of mechanical components and cools them, thereby reducing wear of the parts. In addition, it collects all debris from parts of the power unit. To prevent contaminants from spreading further throughout the engine, an oil filter is installed along the oil flow path, which performs the function of collecting small foreign particles.

Therefore, if it is necessary to change the oil, change the filter at the same time and vice versa.

Replacing the cabin filter

1. We find a filter installed under the dashboard on the passenger seat side.

2. Bend the filter latch a little. We take out the old filter. It will be gray from accumulated dust.

3. We take a new filter. It consists of corrugated paper or cellulose in a plastic case. We insert this structure in place of the old filter. You may have to tinker, as the filter does not fit easily. In addition, there is inconvenient and limited space under the dashboard. Insert the filter until the lock clicks.

This completes the replacement of the cabin filter.

Using a 8-point square, loosen the drain plug. We substitute a wide container for draining used oil with a volume of at least 5 liters. Unscrew the plug by hand and drain the oil.

Attention! Be careful - the oil is hot.

A steel washer is installed under the plug.

Maintenance. Deadlines

The manufacturer sets the following maintenance periods for a Lada Largus car: every 15,000 kilometers or 1 year, whichever comes first.

Each service requires changing the oil, cabin and air filters. The Lada Largus fuel filter, according to the regulations, must be changed as part of an assembled module along with the fuel pump every 160 thousand kilometers.

Filter articles

Lada Largus for 2022 is equipped with two types of engines:

• 1.6 l 8 valves (90 hp);
• 1.6 l 16 valves (106 hp);

Until 2022, Lada Largus cars were equipped with two more types of engines from Renault: 1.6 l Renault K7M / 8 valve. (84 hp) and 1.6 l Renault K4M / 16 valves. (102 hp). The consumables for them are completely different. If you have a car manufactured before 2022, be careful!

In our case, the article numbers for filters for two types of domestic engines are the same and are presented in the table below:

Let's examine the puck. If the rubber seal is damaged, replace the washer with a new one. If you do not have a new standard washer, you can install a copper washer with a hole diameter of 18 mm under the plug. Drain the oil for at least 10 minutes. We wrap and tighten the drain plug. We remove oil leaks from the engine oil pan.

How to distinguish a fake from an original filter

LADA Largus is equipped with original LADA/Renault equipment with catalog number 7700274177. Its cost is not so high compared to other elite brands of the automotive industry. However, there is a category of car enthusiasts who prefer to save money and install non-original copies. In this case, there is a certain risk of buying a low-quality counterfeit product.

When purchasing a spare part from another manufacturer, the driver may encounter some problems that he will discover after installing the equipment. Therefore, it is better to purchase a tested and certified device.

Some distinctive features of the original part and its analogue:

1. The original filters have a W-shaped cleaning element without any flaws. Analogues also have an “accordion”, but cannot boast of the quality of material laying.
2. On a non-original part, the inscription on the body, if rubbed, may be erased.
3. If you pay attention to the filter housing, there is a barely noticeable extruded circle on the “native” device.
4. There is paint spraying on the surface of the filter paper (in cross-section) in analogues.
5. In the real part, the bypass valve spring has an hourglass shape. The non-original one has an even cylinder.
6. The names of the two samples may be slightly different.

Non-original filter equipment suitable for Lada Largus

There are quite good analogs of original spare parts that are successfully used on Lada Largus.

Unscrew the oil filter by rotating it counterclockwise.

If this cannot be done manually, loosen the filter with a puller. If there is no puller, we pierce the filter housing with a powerful screwdriver (closer to the bottom of the filter, so as not to damage the motor fitting) and unscrew the filter, using the screwdriver as a lever. We clean the filter seat on the cylinder block from dirt and oil drips. Apply engine oil to the filter sealing ring and screw the filter in by hand until the sealing ring touches the cylinder block. Turn the filter another 2/3 of a turn to seal the connection. Pour 4.8 liters of engine oil into the engine through the oil filler neck. Close the oil filler cap. We start the engine for 1–2 minutes. We make sure that the indicator of insufficient (emergency) oil pressure in the engine has gone off in the instrument cluster and that there are no oil leaks from under the drain plug and filter. We stop the engine. After a few minutes (so that the oil has time to drain into the oil pan), we check the oil level and bring it to normal. If necessary, tighten the oil filter and drain plug. We install the power unit protection in place.

Lada Largus: changing the oil and oil filter in a 16-valve engine

Operating principle of the oil filter

The cleaning component of Lada Largus consists of dense fabric (paper), the structure of which includes synthetic, cellulose and glass fibers. By passing the flow of engine oil through itself, the fabric traps dirt and wear products from the metal parts of the engine.

To give the filtration element additional rigidity, it is treated (impregnated) with a special resinous agent. The paper is folded like an accordion and rolled into a cylinder, onto which metal rings are glued.

A feature of the filter is that after turning off the ignition and completely stopping the car engine, a small amount of oil fluid should remain in the system. For this purpose, the oil purifier is designed with an anti-drainage rubber valve. Often, it is the violation of its integrity that many non-original spare parts and counterfeits suffer from.

When purchasing a filter device, you must adhere to the recommendations of the vehicle manufacturer.

Every part of a car has its pros and cons. Here are a few disturbances that may occur during the operation of the filter device:

• if the filter is very dirty, the bypass valve opens and circulation of uncleaned engine oil begins, which leads to rapid wear of engine parts. If you do not pay attention to this in time, you can get more serious problems in the operation of the engine;
• installation of a new device should only occur simultaneously with changing the lubricant, otherwise the old uncleaned oil will continue to clog the filter;
• A rare problem, but it exists when coolant enters the system due to a leak.

Replacing the fuel filter

According to the maintenance regulations, the fuel filter is not changed often: every 160,000 kilometers. You may never have to do this. But there are times when it is necessary to change the fuel filter earlier. The fuel filter may become clogged due to the use of low-quality fuel, and dirt, water or oil may enter the gas tank. Result: the car does not start or does not gain speed. Recommendation from experienced mechanics: the fuel filter needs to be replaced.

The work required to replace the fuel filter is as follows:

1. Remove the back seat and lift up the carpet.

2. Remove the inspection hatch cover.
3. Disconnect the electrical wiring, then the fuel hoses. Gasoline may spill. We follow safety precautions!

4. Unscrew the fixing ring and remove the fuel filter assembly with the pump.
5. Let's move on to the workbench. We change filters: coarse and fine. We check the operation of the pump. If necessary, we change it.

6. We assemble the disassembled unit. Carefully install the fuel filter in reverse order.

The fuel filter replacement is complete.

What kind of oil and in what volume is poured into the Largus engine

It should be noted that this car uses five engines:

• 8 valve - VAZ-11182;
• 8 valve – VAZ-11189;
• 8 valve – K7M;
• 16 valve – K4M;
• 16 valve – VAZ-21129.

Each engine has its own crankcase volume. In this case, the manufacturer pours the same oils into all engines of the same manufacturer. In this case, arguing about which oil is better for Largus is pointless. However, there are several good options:

According to the passport, the volume of the VAZ 21129 crankcase is 3.5 liters. But paired with a box from Renault, its volume increases, as an empty cavity appears as a result of using the adapter plate.

The table shows the brands of motor oils that the manufacturer pours into its engines within the walls of the enterprise. These same liquids are used when visiting a dealership. However, it is not prohibited to pour the following brands of oils:

• Shell Helix Ultra 5W40;
• Mobil;
• MANNOL ENERGY JP 5W-30;
• Shell Helix HX-8;

Domestic engines are less sensitive to fluid quality, unlike their counterparts from France. Therefore, they are able to digest even low-grade domestic oils and are not afraid of counterfeits.

In addition to the engine oil, you must select the appropriate filter. The articles are as follows:

After this, you can start changing the lubricant in the engine.
