Tips for replacing the Granta liftback fuel filter with your own hands

The cleanliness and timeliness of oxygen entering the fuel equipment is extremely important to ensure the performance of the vehicle and the power unit as a whole. The completeness of combustion of the fuel mixture determines throttle response, acceleration dynamics, and power indicators. Lack of air leads to depletion of the combustible mixture, engine detonation, and reduced power.

In order to maintain the functionality of the technical product, the manufacturer recommends replacing the fuel filter of the Lada Granta liftback every 30,000 km. mileage In this case, maintenance is carried out every 15,000 km. In practice, this interval is not maintained. Car enthusiasts who care about their vehicles update cleaning elements every 10,000 km.

The replacement process is not at all complicated; every car owner can do it. Specialists are rarely called to the workshop in case of detection of a large-scale breakdown or other malfunction that requires prompt intervention by a professional.

What tool will you need?

After the final decision has been made on self-prevention with subsequent replacement of worn-out elements, we check the availability of the following tools:

• set of heads;
• flathead and Phillips head screwdrivers;
• rags;
• new filter, according to the catalog article;
• empty container for storing waste.

Important points

The procedure outlined above seems quite simple, but, nevertheless, there are a couple of nuances that should be mentioned.

Firstly, gasoline. When the gas lines are unscrewed, it begins to flow directly onto the cap (this happens especially often if the car owner forgot to relieve the pressure in the gas line using the breather, as mentioned above). Yes, a little gasoline leaks out, but the smell of gasoline in the cabin is not what a car owner needs, right? Therefore, before removing the fuel lines, you should put a cloth on the pump cover and carefully insert it with a screwdriver into all the cracks. The rag will absorb the leaked gasoline, then you can throw it away, which will help get rid of the smell in the cabin.

Secondly, the fuel pump retaining plate. As practice shows, this is a fragile thing, and breaking it by carelessly prying it with a screwdriver is not just easy, but very easy. But it’s difficult to find this part on sale; it is only sold complete with a complete fuel pump, and this is a waste of money. The matter is further complicated by the fact that it is not always possible to move this plate out of place with just a flat screwdriver (especially if the car owner is trying to disassemble the pump for the first time), so sometimes you have to resort to using a hammer and chisel, and this, in turn, increases the risk many times over plate breakage.

As you can see, there are no difficulties with independently replacing the pump grid on the Lada Kalina, and if you strictly follow the above instructions, even those who are doing it for the first time will not have any problems. The main thing is to be patient and follow safety precautions. It is imperative to remove the terminal from the battery! Otherwise, a banal mesh replacement can turn into a fire.

Replacing the fuel pump mesh on Grant

I think there is no need to explain once again that the design of the fuel pump on Kalina and Grant cars is not at all different. That is why the entire process of replacing the components of the fuel pump on the above cars will be the same. Also, it is worth noting that when compared with the models of the 10th VAZ family, there are some points that differ.

Where is the fuel filter installed?

As standard, the purifier is mounted above the fuel tank, on the right side, closer to the threshold of the body. Some car tuning enthusiasts practice moving the filter to the engine compartment, having previously lengthened the fuel supply lines.

However, such a configuration is not entirely correct, at least from a security point of view.
The location of the source in an area of ​​elevated temperature conditions is unsafe. Related link:

Fuel pump mesh

The mesh is a coarse fuel filter and serves to protect the fuel pump from large particles of debris entering the fuel pump, which can damage it.

The mesh is located in the fuel pump glass and to replace it you need to dismantle it.

Replacing the Granta fuel pump mesh

Relieve the fuel pressure from the fuel line. We dismantle the gas pump glass and take out the pump itself, replacing the mesh in it and assembling the structure in the reverse order.

How to choose the right fuel filter

The standard cleaner on the Lada Granta liftback, like on the sedan, is black and opaque. Inside there is paper filling in the form of an accordion. This design does not allow for full and timely detection of cell blockage or foreign objects getting inside.

A good solution was provided by third-party manufacturers, including foreign ones. They made the structure transparent. Which is convenient and practical to use. The driver can open the hood at any time and assess the degree of clogging, replace the Lada Granta Liftback fuel filter with a new one as necessary.

The issue of quality and originality remains important. Lack of information from owners, fraud by sellers, and a wide range of products mislead an inexperienced driver. To minimize the possible risk of buying a counterfeit, always check the catalog part numbers with the actual data in the operating instructions for your car. However, the manufacturer cannot list all verified suppliers, so the list will be limited.

In this case, use the services of official representative offices and dealers. Do not purchase parts or components at unusually low prices, since cheapness is a sign of low quality.

The above list is not exhaustive and is presented for informational purposes only. May be supplemented with new catalog items as new products are released.

Required spare parts

The manufacturer recommends replacing the fuel filter on the Lada Granta 8-valve and 16-valve models with article number 21230111701082. You can purchase foreign-made fuel filters:

• Bosch with article number 0450905273;
• Mann with article number WK 512;
• MAHLE with article number KL83;
• Filtron with article number PP905.

The average price of a node is 420 rubles.

In addition to routine maintenance after 20-30 thousand kilometers, the LADA Granta fuel filter is replaced when the following signs appear:

• The Granta engine does not start well;
• power and dynamics decreased;
• the engine runs intermittently or stalls at idle; Fuel consumption increased and black smoke appeared from the exhaust pipe.

Note: the cause of the listed symptoms is not necessarily the Granta fuel filter. These manifestations are possible due to malfunctions of the fuel pump, ignition and injection systems, or when filling with low-quality fuel.

To replace the filter, it is not necessary to go to a service station. If you have an inspection hole and a minimal set of tools, you can replace it yourself. You can similarly replace the filter by lifting the car on a lift.

Where is the LADA Granta fuel filter located?

The filter element is located in a rather inaccessible place, so the question arises: “Where is the fuel filter on the Grant?” The filter is located under the bottom of the car near the gas tank. More precisely, its location can be defined as “under the trunk, to the right of the space for the spare wheel.”

Typical signs of filter contamination

• unstable operation of the power unit at idle;
• reduction in power, including without load;
• the engine “requires” a shift to lower gears before an ascent or hill;
• starting the engine is complicated, both “hot” and “cold”;
• Gases and exhaust periodically shoot out from the exhaust pipe, which indicates that the combustible mixture is unbalanced, depleted, or enriched.
• A burning smell can be heard near the car, which indicates incomplete combustion of the mixture inside the chamber and the formation of an excessive amount of soot.

Operating principle and specific purpose of the filter

Any car, regardless of its design, has a fuel filter. (pictured is a fuel filter on a VAZ-2115 )

Naturally, it differs in terms of fuel type and its supply to the car. But still, there is a filter. In the case of the Lada Granta car, this is a traditional filter element used everywhere in injection-type cars.

The main task of such a filter is to catch and sift out particles of dust, rust and other inclusions so that they do not penetrate into the fuel line. If such a filter did not exist, the motor would very quickly fail, since a lot of solid particles that could damage the cylinder walls would get into it.

The filtration system has an established principle of operation, which involves two degrees of purification. The first stage involves catching the largest contaminants, followed by the second stage of fine cleaning, which is usually called a fuel filter in the traditional sense of the word.

Fuel filter cross-section

Fuel filter from Granta in a section (removed from the car, not new)

But it must be located in front of the engine and after the fuel tank.

For Lada Granta, there is a restriction on the penetration of particles larger than 10 microns. If you do not adhere to this recommendation, the injector nozzles will clog very quickly, after which the engine will become unstable, and it will begin to move unevenly with breaks. And, in the most difficult cases, the working cylinders will be damaged.

Given the increased pressure in the fuel line, the filter must be made of metal or high-strength plastic.

Recommended fuel filter replacement interval

The manufacturer in the operating instructions prescribes replacement every 30,000 km. In practice, the specified interval is irrelevant for a domestic car, given the quality of the fuel.

Car enthusiasts recommend carrying out preventive maintenance followed by replacement every 10,000 km. In this case, you can count on the longevity of the technical device. Premature replacement of the cleaning element is also justified in the case of systematic filling of the tank by 40 - 60%. The likelihood of sediment formation increases several times.

Why might the mesh need to be replaced?

Two grids - dirty and clean

First of all, because of bad gasoline. If you regularly refuel at dubious gas stations, then it’s only a matter of time before the fuel pump fails. Purification of gasoline from impurities in the gasoline pump occurs in several stages, and the mesh of the gasoline pump is the first line of defense, so to speak. It is the first to absorb all large particles of impurities and dirt. After passing through the mesh, gasoline enters the fine fuel filter, then passes through another mesh (which is located near the fuel pressure regulator), and finally goes through the third mesh (located directly in front of the injectors). If problems arise in any of these areas, you won’t be able to go far. The car engine simply will not start. Or it will start, but will work unevenly and jerkily.

recommends changing fine filters every 30,000 kilometers

. But he doesn’t give any recommendations about the fuel pump mesh. Therefore, many car owners forget to change this grid, and remember about it only when the engine begins to behave strangely.

The general rule is: if the car has traveled 60,000 kilometers, the mesh should either be cleaned or replaced. It is advisable to clean it only if there is no serious mechanical damage to it. But if the machine has traveled the distance indicated above, then the mesh in the pump is often worn out to such an extent that it is easier to throw it away than to clean it.

Procedure for replacing the fuel filter Lada Granta liftback

Before replacement, we carry out comprehensive diagnostics in order to study the general technical condition of the car and identify possible breakdowns. Based on the data obtained, we make a decision on the advisability of replacement. Often, inexperienced drivers take the obvious for what they want. When, instead of installing a new purifier, a high-voltage wire needs to be replaced due to insulation damage.

The fuel in the line is under pressure, you can’t just take it out and replace it, you must first release the atmosphere.

• We place the car within the perimeter of the repair area, turn off the engine, squeeze the handbrake, open the luggage compartment lid;
• On the left side of the steering wheel, on the dashboard, remove the fuse responsible for supplying power to the unit;
• We start the engine, let it idle until it stops completely, until the fuel runs out;
• Leave the starter on for 4 - 5 seconds to completely relieve pressure;
• The work in the cabin is completed, then we squeeze the tip - the retainer on the filter fitting, and remove it;
• There are fuel residues inside the filter, carefully lower it into a plastic container;
• We insert the fuel filter of the Lada Granta liftback and reassemble the structure.

It is important not to confuse the direction of the fittings. Pointer “from the tank towards the engine”. If installed the other way around, the engine will not start due to lack of pressure and fuel supply. Finally, we start the engine and check the tightness of the system. If necessary, tighten the fasteners. The work on independently replacing the fuel filter on the Lada Granta liftback has been completed.

First you need to reduce the pressure in the car's fuel system. Normal pressure in the fuel system is at least 3 atmospheres, so if you remove the filter right away, you and everything around you will get dirty with gasoline. You can use two ways to reduce the pressure in the fuel system.

1. It is necessary to remove the fuse that controls the operation of the fuel pump. Its number in the mounting block is F21, capacity 15A.

   The 5th one from the top is the fuel pump fuse. For ease of removal, there are special tweezers in the mounting block. It is red on top.

2. Or lift the back sofa, find the fuel pump and remove the power terminal from it.

We recommend: How to check the compression in a car engine with your own hands?

In all cases, you then need to start the car and wait until it stalls.

1. Next, we climb under the car body and use a flat-head screwdriver to unclip the two latches. Most likely you will have to tinker, since there will be a lot of dirt from below, plus, it often rains heavily in Russia, therefore, the filter clamps may become sour.

2. We remove the filter from the grooves; it is advisable to wrap it with a cloth, as there will be gasoline residues in the hoses.

3. We put on a new one. Observing rotation, there is a directional arrow on the fuel filter for this purpose.

4. We connect the fuel pump to the electrical circuit (either a fuse or a connector, depending on which method you chose to de-energize the fuel pump).
5. We do a test run of the engine. To do this, turn on the ignition, but do not start it. We wait 5 seconds and turn on the ignition again. We wait 5 seconds and try to start the car. Pauses of 5 seconds are necessary for the fuel pump to build up pressure in the fuel system.

The fuel filter replacement is complete. If you have the necessary tools and conditions in the form of a pit or a lift, the replacement should not take more than 30 minutes. Car service centers or dealers will ask you for at least 500 rubles for this service.

Reviews from Lada Granta liftback owners

Vladimir (09.14.18): I recently bought a used Granta, the second owner, the master carried out an inspection and recommended replacing the mesh in the gas tank and the fuel filter. Since I don’t understand spare parts, I entrusted the choice to a service station specialist, and they installed LYNXauto LF-1122. I am pleased with the choice, I recommend LYNXauto to car owners to replace the Granta liftback 8 valve fuel filter.

Valery (09/14/18): I am leaving my positive review of the fuel filter from the PURFLUX EP180 company. Good quality, affordable price, originality of products. The engine runs stably, acceleration dynamics are good, consumption is within normal limits.

Vyacheslav (09/14/18): the other day I carried out maintenance on the Lada Granta liftback and replaced all the filters. I didn’t look for anything foreign, I bought something domestic. No worse than analogues, I recommend it.

Air filter

The Granta air filter is installed in the engine compartment in a plastic box. Serves to clean the air supplied to the combustion chamber. Catches the smallest particles of sand and does not let them into the rubbing parts of the engine.

Replacement is carried out every 30,000 km of the vehicle.

Replacing the Grant air filter

To replace, you need to unscrew the 4 screws securing the air filter cover and lift the cover. Remove the old filter and install a new one after first clearing the air filter box of dust and debris.

The filter must be installed in folds along the movement of the car.
