How to change the fuel filter of a Lada Granta car at home?

Author: Ivan Baranov

The fuel filter plays a very important role in the functioning of the Lada Granta power unit. If it were not for this small detail, the engine life would be reduced several times and would not operate at full capacity and with frequent interruptions.

It is to ensure that only clean fuel enters the combustion chamber that a special purifier is installed. It is designed quite simply, but its importance is difficult to overestimate.

Car Lada Granta

It is important to know that replacing the fuel filter of a Lada Granta is a very simple process, for which you should not go to a service station and pay extra money. Any driver, after reading our article and watching the video, will be able to cope with this simple job on his own.

When is it necessary to change?

According to the instructions, the fuel purifier should be changed every 30,000 kilometers or as it becomes dirty. The latter is especially relevant for our conditions. Firstly, the low quality of the gasoline itself and, secondly, the unsatisfactory quality of transportation and storage containers. That is why, in order for the power unit of your car to operate steadily and reliably, we recommend replacing it every 10,000 km.

What filters can be installed?

Before installing a new filter element on the LADA Granta, you need to figure out which one is better

select consumables. The purpose of the oil filter is to clean the engine oil from wear particles formed during the operation of rubbing parts, as well as from unburnt solid fuel particles.

Mostly oil filter

The assembly consists of a metal cup in which a filter element is installed, folded in the form of an accordion, and two safety valves: anti-drainage and bypass.

Oil filter element design

The most popular manufacturers of filter materials that can be installed on LADA Granta

, are the following brands: Renault, Mann, Knecht, Union, etc. One of the best filters can rightfully be considered the original Renault filter 7700274177 and its analogues.

Stages

The oil and oil filter must be changed on a warm LADA Grant after the trip. You should wait about 15 minutes for all the liquid to drain into the crankcase. After this, you can begin a phased replacement.

• First you need to open the hood and unscrew the cap from the oil filler hole so that the lubricant is better than
  the glass.
• Next, you should move under the car to drain the waste. To do this, you need to unscrew the drain plug. Using a wrench, unscrew the drain plug

Be careful not to get burned by the hot liquid that drains.

• You need to place a prepared drain container under the engine.
• While the waste is draining, you can replace the filter element. Using a puller, you need to unscrew the oil filter. Unscrew the old consumable using a puller

If you don't have a special key, you can try to unscrew it by hand. If that doesn’t work, you can use improvised means: a chain, a belt, a flat-head screwdriver, piercing the body with it and using it as a lever.

• The place where the filter was located must be wiped with a clean rag so that contaminants do not get into the new lubricant.
• Next, you need to take a new filter consumable and fill it halfway with fresh oil. Pour new fluid into the oil filter

At the same time, lubricate the rubber seal with this liquid.

Lubricate the rubber seal with oil

• The oil filter should be tightened by hand without force until the rubber band touches the cylinder block. Then the housing is rotated another ¾ turn.
• By tightening the plug on the drain neck, you can fill in new lubricant.
• After filling in the required amount of lubricant, you need to tighten the oil filler cap and start the engine for a few minutes.

Pour new lubricant into the engine

• After turning off the engine, you need to check that there are no leaks anywhere; if there are any, their cause should be eliminated by tightening the necessary parts.
• At the last stage, the oil level is checked and oil is added if necessary.

During the operation of the LADA Granta vehicle, it is necessary to constantly monitor the quality of the lubricant and change it along with the oil filter on time.

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.

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.

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.

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.

What's the best way to change?

It is better to carry out the replacement yourself, because it is a simple process, and the service station will charge you a decent amount for it. In addition, if the vehicle is actively used, such a procedure will have to be performed frequently.

This video shows how the replacement occurs.

Tools

• new cleaner;
• keys;
• container for gasoline;
• screwdrivers;
• tweezers for removing the fuse.

Stages

On almost all Lada Granta car models, the fuel filter is located to the right of the tank next to the rear wheel. It is held in place by mounting clamps. Getting to it is not difficult, but you will have to jack up the car if there is no hole or lift.

The required element is indicated by a red arrow

1. So, first of all, we drive the vehicle into a pit or lift it with a jack.
2. Since the fuel in a vehicle is always under a certain pressure, it must be relieved before intervening in the system.
3. This is done simply. Turn off the ignition. Find where the fuse box is located.
4. Remove the cover.
5. Using the Granta electrical system diagram, we find the location of the fuel pump fuse. In the photo, the red arrow points to it
6. Using tweezers, remove it.
7. Now we need to start the engine, let it idle until it stops due to running out of fuel.
8. Turn on the starter for a few more seconds. All pressure in the system has been released.
9. We find where the fuel cleaning element is located. To make it easier for you, it is mounted on the gas tank near the right threshold of the body.
10. Squeeze the clamps and pull the fuel pipe off the cleaner fitting.
11. We also pull off the second tip of the fuel pipe from the second filter fitting.
12. Now you need to slide the fuel purifier out of the bracket.
13. Let's take it off.
14. There may be some gasoline left in the filter; it must be drained into a previously prepared container.
15. We install the new filter in the reverse order of removal.
16. Please note that the arrow on the body indicates the direction of movement of the fuel, in our case - to the front of the vehicle.
17. We put the tips on the fittings until the latches snap into place.
18. We check how well the filter is secured, whether it is wobbly or loose. It is located between the stops, which are obstacles to its displacement.
19. Replace the fuse.
20. Turn the ignition key. The car may not start immediately, as it will take some time for the fuel to reach the combustion chamber.
21. We look to see if gasoline is leaking at the junction of the fuel filter with the system.

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.”

Gasoline filters for coarse and fine cleaning: replacement and repair

Manufacturers of gasoline filters establish replacement regulations that must be followed. The filters retain their efficiency in cleaning diesel fuel for 20–30 thousand kilometers. The regulated periods may vary under the influence of various factors - from the conditions in which the vehicle is operated, to the quality of the fuel used and driving style. You can judge the need to replace the filter device by symptoms indicating problems with the fuel system or engine.

Signs of TF malfunction

The car engine and fuel filters operate independently of each other, without affecting the operation of each until malfunctions occur. As gasoline filters operate, their internal cartridges become clogged with impurities retained from diesel fuel, which impairs their throughput and increases the resistance of the fuel line. Problems with the filters can be judged by the following signs:

• diesel fuel consumption increases sharply;
• at idle speed the engine begins to malfunction;
• starting the engine when cold is extremely difficult;
• an increase in the number of revolutions is accompanied by failures in engine operation;
• strange braking and jerking of the car while driving;
• loss of power and dynamics.
