Unfortunately, there is no need to talk about the high quality of fuel sold at our gas stations. The fuel contains a large number of different impurities, including small particles of dirt. If the car did not have special devices, engine overhaul would become commonplace. To clean fuel, a car has a special device - a fuel filter.
The mistake of beginners is that they consider this knot to be almost eternal. In this case, the filter element is replaced rarely or not at all. But a contaminated component is dangerous for a car - it harms the engine, since these particles are an abrasive, and when they get into the engine, they settle in the combustion chamber and do not completely burn when ignited, this has a very detrimental effect on the combustion chamber and all engine components. This is why replacing the fuel filter is so important, and this work should be done on time.
The problem is that many car owners don't know how to access the device and replace it. In fact, there is nothing complicated here - all the work can be done with your own hands and without visiting a service station. The main thing is to study the instructions, decide on the location of the unit and prepare the tool.

We start the engine and let it idle until it stops due to fuel exhaustion. Then turn on the starter for 3-4 seconds. After this, the pressure in the fuel system will be released.
The fuel filter is mounted on the fuel tank next to the right side sill.
Fuel filters Kalina
Like many other VAZ cars, the Lada Kalina power system is equipped with two stages of fuel filtration. The coarse cleaning function is assigned to a mesh filter or “mesh”, as it is commonly called. Installed together with the entire fuel module in the gas tank, the mesh protects the electric fuel pump and does not allow large debris to pass through, which can cause a breakdown or clog the fuel line.
The mesh protects the electric fuel pump and does not allow large debris to pass through.
For Lada Kalina you need a mesh with a cut. An inexpensive part costing no more than 50–100 rubles. plays an important role. A clogged filter makes it difficult for fuel to flow into the fuel pump, which is forced to operate at higher speeds in order to maintain the required pressure in the power system. This mode can cause premature failure and replacement of the pump at a cost of about 2,500 rubles.

Before entering the injectors, gasoline goes through one more stage - a fine fuel filter or simply a fuel filter, as it is called in official descriptions and manuals. The power system of the Lada Kalina uses a conventional gasoline filter for injection cars with fittings for hoses equipped with clamping clips. Parts with threaded connections are not suitable.

The market is saturated with fuel filters from various manufacturers. Their prices range from 150–500 rubles depending on the brand. Some manufacturers and sellers value their goods even more expensive. While researching the market, experts from the magazine “Behind the Wheel” did not find any significant differences between the products. Among the main parameters of gasoline purification filters are screening fineness and performance at a given pressure. All filters that have attracted the attention of specialists successfully cope with the retention of pollutants larger than 10 microns in size and easily pass 2 liters of fuel through the filter element every minute.
Choosing a fuel filter of a certain brand does not have a significant impact on the quality of cleaning. Provided that the filter is replaced in a timely manner, price-conscious motorists do not worsen the operating conditions of the engine. The purchase of expensive products is justified if improved parameters are required: minimal screening fineness and a large area of the filter element.

BIG is one of the most popular fuel filters. Champion fuel filters have a relatively low price. Bosch fuel filters are known for their optimal price-quality ratio. Motorika fuel filters are produced in Russia.
Kalina was the first VAZ model, the interior of which was designed using mathematical models using the latest equipment. This provided the compact car with surprisingly good ergonomics - in terms of space and ease of seating, this car cannot be compared with previous front-wheel drive vehicles, although the base, in fact, remained the same!

...and their replacement
The Lada Kalina service book recommends changing the filter every 30 thousand kilometers or more often when using low-quality fuel. Unfortunately, it is impossible to check the quality of gasoline after each refueling, but the likelihood of dirty gasoline getting into the tank is high. For this reason, motorists change the element approximately twice as often as the car manufacturer recommends.
There are no recommendations on service intervals for the fuel pump mesh in the regulations. Motorists determine the need to replace or clean it independently. Signs of a dirty coarse filter include low fuel pressure in the power system and excessively loud operation of the fuel pump. It is useful to inspect the screen element each time there is a need to remove the fuel module.
Work on removing and installing fuel filters is carried out by disconnecting the negative terminal of the battery from the car body. The sequence of operations for the Lada Kalina station wagon, sedan or hatchback, as well as for modifications with eight or sixteen-valve engines, is the same.
Replacing the fuel filter
Replacing the Lada Kalina fine fuel purification element will not take much time. To work, you will need a container for remaining fuel, a screwdriver and a 10 mm wrench.
Before removal, relieve pressure in the engine power supply system:
- Use a screwdriver and open the fuse box hatch in front of the gear shift lever.
Using a screwdriver, use a screwdriver to open the fuse box hatch in front of the gear shift lever. - Pull out the middle fuse that powers the fuel pump.
Pull out the middle fuse that powers the fuel pump. - Start the engine, do not turn it off until the gasoline is completely exhausted. After stopping, turn the crankshaft once or twice with the starter.
It is more convenient to change this element on an inspection pit or a lift. Replacement procedure:
- Disconnect the negative terminal of the battery.
- Squeeze the clamps and disconnect the inlet and outlet tubes from the fine filter. Collect any remaining gasoline that leaks out into a container.
Squeeze the clamps, disconnect the inlet and outlet pipes from the fine filter - Loosen the bolt of the metal fastening clamp.

- Place the fuel inlet and outlet hoses onto the fittings. Press them against the filter housing until the clamps click.
- Restore power to the fuel pump, connect the battery.
- Start the engine, inspect the fuel line connections, and check for gasoline leaks.
When developing the Kalina, VAZ implemented such modern solutions as the production model, such as LED backlighting of the instrument cluster and keys, electric locking for reverse gear, perfectly illuminating headlights with electric corrector and polycarbonate glass without a lens, a heating and ventilation system with recirculation built into the instrument cluster trip computer... Compared to other VAZ models of the late nineties, Kalina stood out, as they say, to everyone.

How often should you install a new one?
According to the manufacturer's service documentation, the fine filter element is replaced every 20,000 km.
For the grid, the service interval is 70,000 kilometers, driven by the tidy. However, in real operation, when it is necessary to change an element, the internal combustion engine itself will tell you. If problems arise, the power plant displays the following symptoms:
- loses power;
- periodically the engine does not start;
- the check light on the dashboard lights up;
- The speed fluctuates or dips occur during acceleration.
All these signs indicate a critical blockage of the mesh. In some cases, maintenance is required after filling with surrogate fuel. Some gas stations mix gasoline with unacceptable substances, which negatively affects the sensitive mesh.
Typical reasons for a clogged filter element on a VAZ
- operating the vehicle for longer than the recommended period;
- filling the fuel circuit with low-quality fuel, low-octane mixture for a long time;
- installation of non-original consumables;
- installation of spare parts from other technical equipment that are similar in appearance to factory ones;
- the machine was left idle for a long time, as a result of which the circuit became clogged and sediment formed.
