Good day to all! In this article we will tell you how to replace the Lada Granta fuel filter . This procedure is very simple, so you can do it yourself without trips to a car service center. In addition, by doing the work yourself, you can save additional money, which can be directed in another direction. When do you need to change the fuel filter on a Lada Granta and how often should you do it?
Maintenance regulations require replacing the VAZ Granta fuel filter every 30,000 km. However, it is better to reduce this figure if the car uses low quality fuel. Or the main signs of a clogged fuel filter began to appear, which will be discussed below.
Signs of a clogged fuel filter in Lada Granta
If the fuel filter is clogged, the first thing you will notice is a floating idle speed. The engine will not run smoothly, but intermittently due to lack of fuel. Secondly, starting the engine will be difficult. Most often, you will need to press the gas pedal additionally when starting the engine. Thirdly, you will feel a loss of power. The car will respond more slowly to pressing the gas pedal.
These are the main signs, when they appear, you should first change the fuel filter. So, from words to action.
Which fuel filter should I choose to replace on a Lada Granta?
A fuel filter with a fitting (clip) is installed on a Lada Granta car. The fuel filter does not have a thread, i.e. secured using quick-release fasteners. The appearance of the filter is shown in the photo below:
Original filter number:
21230-1117010-82
Using this number you can easily find a list of analogues if you do not want to overpay for the original.
Selection of components
Original fuel filters for the 16-valve system are produced and marked with article number 2190-1117010. Their price varies from two hundred to three hundred rubles. A good analogue would be a part from LADA, produced under number 21230-1117010-81. Filters that are usually found on Opel Astra G, Chevrolet Aveo or Lanos are also suitable for Lada Granta. The fact is that their characteristics and sizes are similar.
Please note that similar strainers are installed on the Lada Kalina and Lada Granta (both 16- and 8-valve). They can be recognized by the cut of the mesh - it is located obliquely.
Expensive filters not only have a larger filter surface area, but also guarantee the highest degree of purification. A high-quality, expensive filter will be able to retain particles up to 10-5 microns in size. This is enough for the system to work correctly and smoothly.
Replacing the Lada Granta fuel filter - step-by-step instructions
The fuel filter on the Lada Grant is located next to the fuel tank at the rear of the car. Replacement work is best done in a pit or overpass.
1. Relieve the pressure in the system. There are two ways to go.
1.1 You can pull out the fuel pump fuse, which is located under the front console at the passenger's feet. Then start the car. After 1-2 minutes, the engine will stall because the fuel line will run out of fuel.
1.2. Or you can relieve pressure from the fuel rail by pressing on the valve with a sharp object.
2. Disconnect the fuel supply hoses from the filter. This is done very simply. Just press the lock and pull the hose to the side. Be prepared for the fact that gasoline will remain in the filter and it will inevitably spill. There is no need to be afraid of this, just be careful.
Order of Operations
The fuel filter is located at the rear of the car, under the body. To replace, you will need to install the car on a viewing hole or jack it up.
- The gasoline in the fuel line is under pressure. Any work under operating atmospheres, including replacing the fuel filter, will be accompanied by fuel splashing. Before starting work, you need to reduce the pressure in the system. This can be done in 2 ways: raise the rear seat, disconnect the power, or remove the fuel pump fuse F21.
Part Description
A fuel module is installed in the tank. Under the rear seat of the car you can find a hatch that will provide full access to it.
It is the fuel pump mesh that serves as the coarse filter. Its main task is to maintain stable operation of the element by cleaning the fuel from large particles of dust and dirt, sand and other foreign elements.
The fuel filters on the car are located on the right side of the gas tank, at the threshold level. To gain access to it, you will have to use a jack, a trestle, or an inspection hole. The first method is considered the most unsafe, especially when replacing the filter.
Let's summarize
Based on the above, it is clear that the work does not require qualifications or even serious skills in working with tools. Even a beginner can perform the operation. But, as you know, even the simplest works have their own nuances and tricks. For information on one of them when replacing a fuel filter, watch this video:
Old TF does not require special disposal conditions; it can be sent to a regular trash container.
In most cases, the warranty period of vehicle operation occurs without significant failures in the functioning of systems and components. Before the warranty period expires in the Lada Granta model, there is a need to change the fuel filter, which is shown in the photo. The reason for the need to replace this element is low-quality fuel. The fuel filter is used to prevent foreign impurities, various types of unwanted additives and other fuel contaminants from entering the power system.
The filter element protects the injection system and the cylinder-piston group in the engine. As dirt accumulates in the core of the Lada Grant, the throughput deteriorates until a critical moment occurs. Due to its design, the fuel filter cannot be restored and must be replaced with new elements. In this article we will tell you where it is and step by step how to change the filter.
Causes of fuel filter failure
The fuel at our gas stations is not cleaned as it should be - it may contain dust particles or other contaminants. All this debris ends up in the fuel filter, which does not allow it to pass further into the system. But over time, as pollution accumulates in it, it ceases to cope with its responsibilities. This is very dangerous because it can cause damage not only to many components of the fuel system, but also to the power plant.
If you delay the change, problems may arise with the injectors, valves, and ultimately the engine will refuse to work at all. That is why it is important to know the symptoms of fuel barrier contamination, and if detected, replace this part in a timely manner.
How not to make a mistake with your choice?
Replacing a fuel filter is one thing, but first you need to choose the right element. It should be taken into account that different models require the use of filters that differ slightly in their design aspects. Before purchasing and installing a new element, you should carefully determine its applicability specifically to a specific car, including the LADA Granta. The packaging of the part contains information about the compatibility of the filter with the list of car modifications. If the Lada Granta is present in it, then we confidently buy it. When this fact is absent, it is not recommended to resort to unjustified risks, but to find and purchase a “native” filter, especially since its price is very low.
It would also be useful to purchase and replace a Lada Granta air filter in parallel with the fuel filter. This will ensure that a high-quality mixture is supplied to the engine.
The used LADA Granta filter element cannot be thrown away normally, but requires special disposal. Since during operation it has accumulated a significant amount of chemicals hazardous to health, it should be taken to a collection point for such products.
And so, you learned how to change, and actually where the filter is located in the car. Replacing the fuel filter is not difficult, and the car owner can do it himself.
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

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.
Which fuel filter should I choose?
As you know, all variations of the Lada Grant are equipped with an engine with the same displacement of 1.6 liters. The differences are only in the power that this power unit can produce.
This injection engine, unlike its “carburetor counterparts,” requires a much greater degree of cleaning. So, many experts recommend not stopping at the basic recommendations for a purification degree of 10 microns, but turning to a more significant level of filtration that would guarantee the retention of solid particles with a size of 5 microns. The operating pressure, in the case of the Lada Granta, will vary between 3 and 5 bar.

As for the manufacturer, here you need to focus on your own choice and preferences. However, many Grant Guides recommend taking a closer look at products from the MANN and WIX brands.
When to change the fuel filter?
And, of course, you need to say a few words about when exactly it is appropriate to replace the fuel filter.
On average, a fuel filter loses its characteristics closer to 25 thousand kilometers. But this applies to optimal conditions when the highest quality gasoline is used. In reality, the need for replacement may occur earlier.
Signs of a dirty fuel filter
To find out exactly when you need to replace the fuel filter on your Lada Granta, you need to monitor the main signs of its contamination.
- This usually concerns the engine starting, which will be uneven and delayed.
- Next comes insufficient traction.
- And, with sharp acceleration, the power unit can even stall.
- As for idling, if the filter is dirty, it will be uneven.
Of course, some of these “symptoms” are also typical for problems with the air filter or injectors. But, in any case, this is already a sign that it is necessary to begin a thorough check of the fuel filter, and, if necessary, replace it with a new one.
