Fuel filter for VAZ 2115 - how to replace, which one to choose

Fuel filters for the VAZ 2113/2114/2115 will not differ from each other, since the car is a restyled version of the VAZ 2108, 2109 and 21099. Over the years, these cars were produced in different versions and modifications. Initially, the VAZ-2115 had VAZ-21093 (carburetor) and VAZ-2111 (injector) engines. By the time production of the VAZ-2114 began, carburetors were completely abandoned and all VAZ 2114 and 2113 cars were already produced with an injection type engine. Therefore, fuel filters will differ depending on whether the fuel system is carburetor or injection.

In injection cars VAZ 2113/2114/2115 there are two filters installed, the main one is a fine filter and an additional coarse filter, which is a synthetic fiber mesh filter, which is located in the tank along with the fuel pump.

To gain access to the fuel filter, you need to use an overpass, since the filter is located under the rear part on the bottom in the form of a cartridge. The process of replacing the fuel filter for both cars with 1.5 and 1.6 liter engines is basically the same, the distinctive features will be different fasteners ( for models with a 1.5 l engine, a hexagonal fastening is used, for 1.6 l engines a spring fixation is installed with latches), and during installation, be sure to pay attention to the position of the arrow indicating the direction of fuel flow. For a car with a 1.5 liter unit, the arrow should be directed from the right to the left side; on a 1.6 liter engine, the arrow should accordingly be directed to the revolution.

The fine fuel filter for injection vehicles VAZ 2113, 2114 and 2115 has the same design. Lada has assigned these filters the following catalog numbers: 21230111701000, 21230111701001, 21230111701002. These fuel filters have a “fitting” type connection. The fuel filter, which is designed on a turnkey basis, has the original spare part number - 210801117010.

The overall dimensions of these fuel filters are slightly different from the original part, but they are suitable for installation.

The coarse fuel filter VAZ 2113/2114/2115 is a mesh and is installed together with the fuel pump in a single module located in the tank. For this reason, this filter is not sold separately.

What fuel filters are installed on VAZ 2109/2114/2115 cars

VAZ cars of the listed models are equipped with filters designed for various power plants. They are divided into two types: for coarse cleaning (mesh in the fuel pump) and fine cleaning FTO (separate filter).

The VAZ coarse filter is located inside the fuel pump

We recommend: Self-repair of VAZ-2103 engine

Filters intended for carburetor systems are made of durable and transparent material, usually plastic. The transparency of the case allows you to monitor the state of cleanliness and promptly change consumables. These models are capable of cleaning fuel in a zone of 15–20 microns. One of these materials is placed inside them: felt, felt or paper.

For injection systems of VAZ cars, cleaning of a much higher level is required. Therefore, the filters for injection “nines”, VAZ 2114 and 2115 are different. They are made of stainless steel and are installed separately.

For rough cleaning, plate-slit, mesh and belt are used, which trap debris found in the fuel. On the contrary, PTO uses elements made of porous materials.

Which ones are better

Fuel filters, especially for engines with injectors, must have the required cleaning quality. Therefore, the best cleaner can be called the one whose throughput is at least 5–7 microns (injector) and 15 microns (carburetor). In addition, it should not fail in the case of a pressure of 3-5 bar.

It is also recommended to pay attention when choosing the method of fastening the fuel system pipes. There are models with hexagonal locking and models with snap fastening. The latter are more convenient in terms of replacement.

Approximate cost of replacing fuel filters

Replacement takes approximately 30–50 minutes, depending on the part model. In this regard, the cost of the procedure at a service station also varies, which is calculated according to the amount of time spent.

In fact, it is recommended to initially negotiate with the service center employee about the cost of the procedure, agree on the time, etc. As a rule, the replacement price starts from 700 rubles and does not cross the line of 1000–1200 rubles.

Fuel filter VAZ 2113/2114/2115 carburetor

All carburetor “thirteen”, “fourteen” and “fifteen” cars are equipped with a fuel filter that does not differ from the vehicle’s equipment. On VAZs with a carburetor engine, the fuel filter is located in the engine compartment, next to the vacuum brake booster and brake fluid reservoir. Made in the form of a small cylinder of transparent plastic. The VAZ-2108-15i fuel filter is produced by LAAZ “Livny 1.3”. Catalog number of this part: 21081117010.

When to change fuel filters?

According to routine maintenance, the manufacturer recommends replacing filters at least every 30,000 km. But depending on the quality of the gasoline being poured, the replacement period must be reduced to 15,000 km on injection engines and to 20,000 on carburetor engines.

How to Change the Fuel Filter on a VAZ 2115

Replacing the fuel filter on VAZ 2113, VAZ 2114, VAZ 2115

Thanks to this device, the fuel filter cleans the fuel of foreign substances that should not be contained in it, for example, water or dirt contained in gasoline. But over time, like any other part, the fuel filter becomes unusable and needs to be replaced, but not all people know how to do this, and therefore, especially for these people, we have written this article detailing the process of replacing the fuel filter. in car.

To replace the filter, you will need to stock up: just a set of wrenches and a rag are also useful for cleaning the filter from dirt contaminated with it for easy operation!

Why is the fuel filter not working?

Let's start by answering this question because we are asked this question very often, so this filter becomes unusable only due to low grade gasoline which contains dirt, water and rust particles and other substances through which the filter runs causing it's a little wear and tear.

Where is the fuel filter?

Essentially, it stands in the same place on all fuel-injected cars from the VAZ family, namely, it is located next to the gas tank of the car at the back, so if you want to see it freely, you will have to bend down to find the gas. the tank is behind and only then you will be able to understand the fuel filter . See the photo below for more details:

When should I replace the fuel filter?

In general, it should be replaced every 15,000–30,000,000 km. Why is there such a difference in these numbers and closer to the ones you want to keep, you ask? We explain! As you understand, after reading the text just above, the fuel filter becomes unusable due to the low quality of fuel poured into our cars at gas stations, so if you are sure that the fuel you fill is good and of the quality that you need, then this filter You can safely change every 30,000 thousand km, and if the fuel you fill at the gas station is of poor quality and contains all kinds of foreign substances, then start replacing this filter after 15,000 thousand after installing a new one.

But, nevertheless, these numbers do not matter much, because this filter can get dirty even faster, and the first signs that the car will show are poor unstable engine operation, as well as loss of dynamics during acceleration and with a sharp pedal, and just like a car with a clogged filter, it may just start dragging.

How to replace the fuel filter on a VAZ 2113-VAZ 2115?

Before replacing this unit, be sure to take out the wrench and use it to unscrew the nut that secures the negative terminal to the battery terminal so that the current in the motor disappears and you can operate properly! (See “Replacing the battery on a VAZ”, article 1).

VAZ 2115: replacing the fuel filter with your own hands

Replacing a VAZ 2115 fine gasoline filter, the arrow must coincide with the direction of fuel movement

Replacing the fuel filter in a VAZ 2115 may come as a surprise to some owners, because they have no idea about its location and existence before problems arise. According to the manufacturer's recommendations, replacing the VAZ 2115 fine fuel filter should be carried out after every 30 thousand kilometers of vehicle mileage. However, the manufacturer considers this mileage provided that the quality of gasoline at gas stations meets the highest standards.

Fuel filter location

The fuel filter on the injection VAZ 2115 is located under the bottom. It's cut into the highway. The filter is located in a niche near the tank.

The coarse mesh filter is assembled with the fuel module, which is placed in the gas tank.

PROBLEMS ARISING

Unfortunately, the quality of fuel today is far from ideal and unpleasant situations have become common when jerks and dips appear during the movement, first at high speeds, then at low speeds. So:

When the car begins to start poorly or does not start at all, there can be many and very different reasons; the owner cannot always guess that it is necessary to replace the VAZ 2115 fuel filter
Since the driver’s opinion is that there seemed to be no problems before leaving, so only over time will the owner perhaps understand the real cause of the problem, which is hidden in the contamination of the fuel filter
Some try to correct the situation by changing the oil in the engine or gearbox, others hope that their problem will be solved by flushing the injector or computer firmware
The real cause of problems is dirt, which is present in large quantities in the fuel.
It is natural that the dirtier the gasoline, the faster it clogs the filter, and this will more often cause dips and jerks to bother you while driving.
The only correct way out of the situation is to replace the fuel filter on a VAZ 2115
At the first such symptoms, the filter element should be replaced, regardless of the mileage of the car, at the time of trouble, even if it is much less than thirty thousand
The procedure should be carried out in a designated place on an inspection ditch or overpass, do not dump fuel on the ground, place a container, remember about the environment

Attention: When repairing a car, do not forget that gasoline is highly flammable, so smoking or using a lighter when replacing fuel filters or any repairs related to the fuel system is life-threatening! In addition, fold rags soaked in gasoline separately and then the likelihood of a fire or explosion during repairs will be minimal. Always keep a powder or carbon dioxide fire extinguisher nearby.

You must first find out what brand and type of filter you have, so as not to make a mistake when purchasing a replacement one.
When installing a new filter with your own hands, replace the O-rings on the tubes
You should also pay attention that the arrow drawn on the filter is in the direction of the movement of fuel in the line, otherwise your problem will return very soon
Next, we will describe replacing the fuel filter on a VAZ 21154 in its technological sequence
This sequence practically coincides with replacing fuel filters VAZ 2110-2115

FINE CLEANING ELEMENT

First of all, let's look at how to replace a fine gas filter on a VAZ 2115:

After you have rolled the car onto the overpass, you should relieve the excess pressure inside the fuel line
We reduce the pressure in the fuel system; to do this, disconnect the terminal from the fuel pump in the tank, start the engine, when it stalls due to lack of fuel, disconnect the terminals from the battery
Spray WD-40 at the connection between the filter and the main line, and wait a few minutes
After this, we go down under the car, and use keys “17” and “19” to loosen the tightening of the tube tips to the filter, photo below

Using two keys, unscrew the tubes from the filter

Finally unscrew the nuts of the tube tips and remove the tube tips from the filter
Fuel will spill out of the filter and pipes, that's why you need a bucket
Then it remains to unscrew the coupling bolt on the filter mounting clamp

Unscrew the coupling bolt

Removing the filter
As you can see, replacing the VAZ 2115 gas filter is not a difficult job.
Then the O-rings that are on the tips of the tubes
We check their condition
If they are torn or have lost their elasticity then the rings need to be replaced
After this, screw on the new filter, do not forget to put the o-rings back in place.
Remember the direction of the arrow on the filter so that it is in the direction of fuel flow
After installation, connect the fuel pump and terminals to the battery, and let the engine run for about five minutes, check from below to see if gasoline is leaking, if it is leaking, tighten the pipe fittings
Replacement of the VAZ 21154 fine fuel filter is completed

ROUGH FILTER

The electric gasoline pump is located in the tank in all VAZ cars. It is located in a housing with a mesh on it (for rough cleaning). Getting to the pump is easy, you just need to remove the rear seat and there is a hatch:

You need to unscrew its fastening, under the hatch there will be a pump housing with auxiliary units attached to it
The entire pump is replaced if it breaks or the fuel level sensor attached to it breaks.
Damage can occur from driving with an empty tank, due to air getting into it and insufficient cooling
We change the coarse mesh if replacing the previous filter did not eliminate jerking and dips in the movement of the machine
The mesh is located in the pump housing, so it will have to be removed if it is replaced.

Replacement Tools

The instructions for replacing the mesh recommend the following tool:

Keys “7” (head is better), “17”, “19”
Pliers
Two screwdrivers Phillips and slotted
Liquid WD-40
Pump used to inflate wheels
Rags
The mesh is new
O-ring for rubber pump
Possibly a fuel supply hose if the old one is roughened or cracked

Let's move on to replacement

Attention: It is recommended to carry out all work related to the fuel pump with an empty tank. It is prohibited to smoke, use matches or lighters during work, or perform work with a full tank of gasoline.

So:

First you should, as in the previous case, relieve the pressure in the line
Then remove the seat and unscrew the hatch
Disconnect the terminal
Unscrew the fittings using the “17” key
Before unscrewing, it is better to fill the connections with WD-40, pump nuts too
After this, unscrew the nuts with the “7” key
The “ground” of the pump is screwed to one of the nuts, do not forget about this when assembling

Unscrew the nuts that secure the pump

Remove the pressure ring
Pull out the pump housing

Attention: Be careful! A gasoline level sensor is attached to the housing; otherwise, when removing it, you will bend the pointer and the gasoline level readings will be incorrect.

Replacing a level sensor - this is the price of negligence and carelessness
Remove the rubber seal
Detach the lower glass
It just snaps off
It is usually full of dirt
Remove it with a rag and wash it
If the glass cannot be pulled out together with the body through the hole, it usually falls into the tank
You don't have to worry, it can be easily removed by hand, so pull it out
Remove the mesh (see Why you need to replace the mesh of the VAZ fuel pump) by simply pulling it up
After that, put on a new one and you can put everything back together.
If anything in the actions or order is not clear to you, delete the video

Mesh, also known as a coarse filter

VAZ 2115 how to replace the fuel filter is now clear to everyone, get started and remember about safety precautions.

Signs of a dirty fuel filter

If you experience any of the following symptoms, your fuel filter may be clogged and needs to be replaced.

Increased fuel consumption (Causes of high fuel consumption on VAZ).
Unstable idle.
Dips when gaining speed.
Poor engine starting.
Troubles the engine.

In addition to the fuel filter, these signs also indicate a malfunction of the following elements: ECU, Spark plugs, High-voltage (HV) wires, DPKV, Mass air flow sensor, DD, DPS, Idle air control. So, when replacing the fuel filter, keep this in mind.

How to replace the fuel filter?

What we need to replace:

fuel filter;
O-rings;
keys at 10, 17, 19;
empty clean container for gasoline.

Removing the old filter

Relieving pressure from the fuel line: How to relieve pressure in the fuel line?
We treat the filter mount with penetrating lubricant (wd-40) if you have a 2111 1.5 liter engine.
We take keys 17 and 19. With one we hold the filter from rotating, with the other we remove the fitting of the fuel supply line.
Take an empty 0.5 liter container and pour out the remaining gasoline from the fuel line.
We unscrew the fitting of the fuel outlet pipe.
Disconnect the fuel line tubes from the filter and use a 10 mm wrench to unscrew the fuel filter coupling bolt.

With the fuel filter of a 1.6L engine, everything is much simpler - remove the fuel line tubes from the filter by pressing the fuel line clamps.

Installing the fuel filter

First of all, we change the O-rings at the ends of the fuel pipes.
Install the filter in reverse order.

The only thing to consider is the direction of the filter. There is an arrow on the gasoline filter housing indicating the direction of gasoline flow. If you have a 1.5 engine, then the arrow should be directed to the left side, if 1.6 - then to the right side.

Checking the connection

Turn on the ignition for 6-7 seconds, then look at the fuel filter and look for traces of leaks.
If necessary, you need to fit the fuel pipes onto the filter more tightly.

Step-by-step procedure for carrying out replacement work on a VAZ-2114

Before starting work on dismantling the fuel filter, it is necessary to relieve the pressure in the system. This must be done so that during removal it does not splash and flood everything around.

To relieve pressure, first move back the rear seat, open the gas tank hatch and turn off the pump power supply.
The arrow marks the location of the pump under the rear seat
Removing the protective cover
Diagnosing the fuel pump
Next, we start the car and leave it running until the engine stops working and stalls.
After this, we try to start the car again to make sure that there is no fuel in the system.
At this point, work on relieving the operating pressure in the system can be considered completed.

We recommend: Flushing the engine cooling system - 6 popular methods for quick and high-quality cleaning

Alternative way to relieve pressure

If you do not feel confident in the correctness of such a procedure, you can remove the fuse from the block, located there under the marking F3 , which is responsible for powering the fuel pump.

The fuse box under the hood is marked with an arrow.

When the fuse is removed, start the engine and also wait until all the fuel is gone. The main thing is, after completing all the work, do not forget to put this fuse back in place.

Dismantling process

As mentioned above, depending on the type of engine, the method of fixing the filter differs from each other.

Engine capacity 1.6

So, if you are the owner of a 1.6- liter engine, it is enough to just press the clamps of the fuel pipes with a little force and remove them from the place of fixation.

Engine capacity 1.5

And if you have 1.5 -liter engine, then you need to do the following:

Carefully apply lubricant to all fixing parts to make them easier to dismantle.
Next, remove the fitting from the fuel line drive using keys “17” and “19”.
The nuts to be unscrewed are indicated by arrows.
During these actions, it is necessary to secure the connection tightly to avoid scrolling.
Leave the remaining gasoline that will spill out during dismantling to drain into a container.
In exactly the same way, remove the retainer from the reverse side and remove any remaining fuel.
When the filter does not hold anything, remove all the fuel supply pipes from it and loosen the housing clamp using a “10” wrench.
This nut usually comes off easily.
Remove the old filter.

The process of installing a new fuel filter (there are nuances)

Before you begin installing the filter, take care to install sealing rings on the pipes, which you should wipe in advance with a dry rag to remove any remaining fuel and other liquids.
The ring is indicated by a red arrow.
Reinstallation is carried out strictly in the reverse order of removal, paying only attention to how the arrow indicates the direction of movement of gasoline along the highway. On cars with a volume of 1.5, from right to left in relation to the side of the car, and on 1.6 vice versa.
After you have installed and secured the new filter in place, connected all the fuel supply wires, you need to turn the ignition key and wait until fuel is pumped into the engine.
Before starting the engine, this procedure must be done 3-4 times so that the entire filter cavity is filled and displaces all available air.
After this, start the engine and let it idle while inspecting the filter connections for leaks. And if such are found, you need to turn off the engine and secure the connections as tightly as possible.
