Largus fuel filter: where is it located and how to replace it? Lada Largus

Like most Lada cars, Lada Largus uses two types of fuel filters: fine and coarse. Both of them are built into the fuel module of the fuel pump, both on Largus with 16-valve engines and with 8-valve ones. Separate replacement is not regulated by the manufacturer, only completely assembled.

The fine filter on Largus is installed in the module in the same way as on Renault Logan. These models have a common platform and the same complex design solution for the fuel purification system. But the service life of fine filters in Europe is longer due to higher quality gasoline. And if for the main filter you can only change the module, then the filter mesh of the fuel pump can at least be cleaned (rinsed) or you can choose an analogue that is suitable for mounting. This procedure will extend the life of both the fuel pump and the fine fuel filter. Therefore, let’s look at which fuel module and mesh filter (the so-called diaper) you can buy.

Replacing the fuel filter Lada Largus

Description

on replacing the fuel filter on Lada Largus

The fuel filter is an extremely important part of the car's system, as it serves to clean the fuel before it goes directly inside the engine. Timely replacement of the fuel filter on the Lada Largus helps maintain the vehicle’s fuel system in good working order and avoid emergency situations at work.

Types of car fuel filters

Fuel filters are classified according to the following parameters:

If you decide to purchase a new fuel filter, then you need to consult with a professional auto mechanic who will help you make the right choice. On the territory of the Alfa service station there are excellent specialists who will be happy to help you select a fuel filter, purchase it and install it in the shortest possible time.

Symptoms indicating the need to replace the fuel filter on a Lada Largus

There are a number of signs by which you can determine a possible malfunction of the fuel filter and the need to replace it

It is very important to immediately notice their presence in order to avoid serious damage to the vehicle engine. These signs include:

All these signs indicate a malfunction, but there is no 100% guarantee that replacing the fuel filter on the Lada Largus will solve them, since this is not the only problem that such symptoms may indicate. To identify the origin of these problems, it is worth carrying out a full diagnosis of the car and eliminating all faults.

Our car service specialists in Nizhny Novgorod recommend timely replacement of the fuel filter on Lada Largus. This will avoid serious damage to the fuel system and vehicles in general.

How often should the fuel filter be replaced?

Each car has its own care recommendations. Typically, the fuel filter should be replaced every 10,000 kilometers. But you should not completely rely on this rule, because the frequency of replacement directly depends on the operating conditions of the car and the quality of gasoline/diesel. Diagnostics can tell you how often your car needs to be replaced.

Disassembling the module: replacing (cleaning) the fuel filter, fuel pump and fuel level sensor

The fine fuel filter (housing), the coarse filter (mesh), the fuel pump, and the fuel level sensor are located in the fuel module complex, which is located in the fuel tank.

Note: According to the regulations, replacement of individual parts of the fuel module is not provided, and in the event of failure of any of its components, the module is replaced as an assembly. However, in an emergency, to replace the fuel pump, clean the fuel filter, or replace the fuel level sensor, the module can be disassembled.

To disassemble the fuel module and replace parts, remove it from the vehicle. (see here)

Disconnect the fuel level sensor wire block from the cover

Remove the fuel level sensor by sliding it in the direction of the arrow

Fuel level sensor 1 – resistor; 2 – slider; 3 – sensor wire block; 4 – float; 5 – float lever

Using a screwdriver, press out the three plastic clips...

...and remove the glass from the fuel module body. Here is a fine fuel filter (housing) and a coarse mesh filter

Remove the rubber o-ring of the fuel pressure regulator.

The glass contains a fuel pressure regulator 1 and an anti-drainage valve 2 .

Having overcome the force of the clamps, remove the fuel strainer.

Wash, blow out, or replace the strainer

Note: to replace the fine filter, some car enthusiasts used a non-original filter with art. LF249M (see photos and dimensions)

Using a screwdriver, press the cover latch...

. answer the lid to the side

remove the spacer spring

Disconnect the fuel pump block from the connector on the inside of the cover.

Remove the fuel pump from the fuel filter housing.

Note: Fuel hoses are secured to the fittings of the pump and filter housing by heat shrink.

After heating the plastic corrugated tube on the pump nozzle, remove the tube from the pump nozzle. Use a stream of boiling water from a kettle or a hair dryer for this.

Attention : before using a hair dryer, thoroughly blow and dry the parts to avoid fuel ignition!

Note: After removing the hoses from the fittings, it may be necessary to replace the hoses to ensure a good seal. Some car enthusiasts used corrugated fuel pump hoses for VAZ.

To install and secure the hose on the fuel pump after removal, some car enthusiasts use regular clamps (but not the worm type)

11 mm. The clamp must be secured so as to ensure a tight connection and at the same time not crush the plastic hose.

We assemble and install the module in the reverse order.

Some misconceptions about the fuel pump (from Behind the Wheel magazine)

The slightest loss of pump seal will immediately lead to a fire, since its brushes constantly spark.

The gas pump is not a sealed structure, and its internal parts, such as the anchor or brushes, are constantly bathed in gasoline. But combustion is impossible: the concentration of fuel vapors is much higher than the stoichiometric one, and therefore it is impossible to ignite them.

Cars with fuel injection need to be refueled more often, but you can’t drive “with a light bulb” at all.

Many people believe that if the tank is not full, the pump will definitely start sipping air instead of gasoline and quickly die. The pump is placed in a plastic cup that prevents fuel from draining during acceleration and roll. The glass is pressed by a spring to the lowest point of the fuel tank. In addition, internal partitions in the fuel tank prevent the ebb and flow of gasoline. What if the fuel runs out? And there will be no troubles: as soon as the pump stops creating pressure, the engine will stall, and the controller will turn off the power in a couple of seconds.

A motor running “dry” instantly fails.

When the internal combustion engine stalls, power is removed from the electric fuel pump very quickly. Therefore, he does not have the physical ability to thresh for a long time in a “dry” mode. In addition, we ran the pumps “dry” for about ten minutes - and nothing: cold body, low current consumption, even noise. Therefore, the pump will not die from lack of gasoline.

Gasoline plays the role of a lubricant in the electric gasoline pump.

The lubricity of gasoline is negligible. It plays the role of a coolant rather than a lubricant.

Excessive pressure in the fuel line is harmful, so when replacing, it is strictly forbidden to install a more powerful fuel pump.

The bypass valve (pressure regulator) in the fuel module monitors the amount of pressure generated by the fuel pump, sending excess fuel back to the gas tank. Therefore, a more efficient pump will not cause any harm. It’s another matter if you installed a weaker engine than standard: when operating at maximum modes, the engine may not have enough fuel and it will begin to “shut up”.

On cars converted to gas, fuel pumps especially often break down.

There are horror stories on online forums: the gas pump on cars with gas equipment is always running, pushing gasoline in a small circle, and therefore fails more often. But this is a normal mode, no different from a working one. Trouble could arise only if there was a complete lack of gasoline in the tank, but this already resembles sabotage. However, the pumps are also not afraid of short-term dry operation.

Fuel filter Lada Largus

Over time, the fuel filter becomes clogged with impurities present in gasoline and requires replacement. Lada Largus is no exception here. How to find out that the fuel filter has become unusable and is “asking” for replacement? Is it possible to perform this procedure independently without resorting to a service? What consequences await the fuel circuit and engine if timely replacement is neglected? A whole lot of such questions may arise, especially for an inexperienced owner of a Lada Largus. Our material is intended to clarify the identified aspects and help many owners solve this problem themselves.

What is a filter element in the fuel system?

The serviceable condition of the system components directly depends on the quality indicators of the fuel used. The average domestic citizen knows firsthand what harm substandard gasoline can cause to these components. The fuel filter performs the function of cleaning the fuel before it is supplied to the fuel rail to the injectors, and then as a mixture into the combustion chambers. If the owner uses a high-quality filter and refills his “horse” only at a proven station, then the system will serve without failures for a very long time.

Specialist recommendation

What is the purpose of the filter?

The uninterrupted operation of 8-valve and 16-valve motors is ensured provided that the fuel supply system operates correctly. Thus, longer preservation of the components of the cylinder-piston group is achieved. The filter is designed to be “responsible” for ensuring the cleanliness of the fuel entering the engine chambers.

This implies the presence of the following functions among the tasks of this element:

• prevent the penetration of solid particles of various origins into the engine along with fuel, which can cause rapid wear, not only damage to the walls of the liners, but also cause irreparable damage to the engine;
• take care of maximizing the service life of the unit.

Operating principle

In the Lada Largus model, the design of the filter component has an unusual solution, so replacing the fuel filter can cause a number of minor difficulties. The unit consists of two components that ensure cleaning of the fuel entering the system. They are located in the pump itself and represent a single module that can be replaced entirely. The manufacturer has included an enviable resource in the filter component, which, if the owner complies with regulatory requirements, can reach 160 thousand km.

Recommendation

Symptoms of malfunction

The most common signs of filter clogging in power supply systems for 8-valve and 16-valve motors are:

• the appearance of unjustifiably high fuel consumption;
• the presence of engine jerks, especially during loads;
• the motor tends to stall;
• interruptions in fuel supply;
• a sharp decrease in the level of traction.

In some situations, the Lada Largus engine begins to stall unjustifiably while in idle mode. You can come to the conclusion that the filter is clogged only after some time, when these symptoms progress in their manifestation. If the breakdown is accompanied by a sudden nature, then it is likely that the reason does not lie in the filter.

Preparatory stage

It is important to know where the filter element is located. Here it is recommended to carry out the following actions:

• ensure that the LADA Largus vehicle is placed on a level surface and achieve stable ventilation of the repair area;
• stock up on the necessary tools and a new pump.

Replacing the fuel filter

1. We fold back the stern seat cushion and open the hatch cover.
2. Turn off the pump power fuse.
3. We start the LADA Largus engine and give it the opportunity to exhaust the fuel present under pressure in the circuit. The unit will stall.
4. Turn off the power by removing the terminals from the battery.
5. Disconnect the fuel lines leading to the pump module.
6. Unscrews the locking disc.
7. Having freed the pump assembly inside the mounting socket, we remove it and replace it with a new analogue. If you only need to replace the mesh filter, perform this action.
8. After assembling the structure using the reverse algorithm, we must check the tightness of the system.

DEVICE AND PRINCIPLE OF OPERATION

An engine, similar to a living organism, is able to “live” for a long time only on the condition that it consumes pure raw materials for its functioning. In terms of the fuel system, the fuel filter is responsible for organizing the purity of the gasoline entering the car engine. This part, simple in structure, performs functions of great importance for any transport. In particular, this Lada Largus unit allows:

• prevent large fractions from entering the injector and cylinders along with gasoline;
• filter out a considerable amount of small fractions also present in the fuel;
• extend the service life of both the engine and the entire fuel system.

Replacing the fuel pump on Largus

Traditionally, two fuel filters are installed on Lada cars to purify gasoline. One of them is called a coarse filter (mesh) and is located in the fuel pump, and the other fine filter is in the form of a separate module (replaced after 10-20 thousand km), which is attached to the bottom of the car near the gas tank. Let's look at how to replace the Lada Largus fuel filter.

If you open the “do-it-yourself repair manual for Lada Largus”, then in the “power system” section you will not find the usual instructions for replacing the fuel filter. The fact is that both filters (coarse and fine) are built into the fuel module (gasoline pump). If it is not difficult to clean or change the fuel pump mesh, then replacing the Lada Largus fine fuel filter will not work; it is only replaced as an assembly with the fuel pump after 120 thousand km. mileage

• fuel pump mesh (articles: FRANCECAR FCR210141, MASUMA MPU025N, NPA NP51109412)
• fine filter (JS ASAKASHI FS22001, JAPANPARTS FC-130S, PATRON PF3924)

To remove the Lada Largus fuel pump, you will need to disconnect the negative terminal of the battery, and then remove the floor covering in the rear seat area by unscrewing several screws. Remove the plastic cover by prying it off with a flat-head screwdriver. Disconnect the connectors and fuel line from the fuel module and remove it by unscrewing it with a special key.

By disconnecting the lower part of the fuel pump, you can gain access to the coarse mesh. It is replaced with a new one, or cleaned and installed in the reverse order.

It is not possible to replace the fine fuel filter; you can only cut its housing, first removing the fuel pump:

Let us remind you that the Lada Largus has other design features, for example, this model does not have a cabin filter.

The fine fuel filter (housing), the coarse filter (mesh), the fuel pump, and the fuel level sensor are located in the fuel module complex, which is located in the fuel tank.

Note: According to the regulations, replacement of individual parts of the fuel module is not provided, and in the event of failure of any of its components, the module is replaced as an assembly. However, in an emergency, to replace the fuel pump, clean the fuel filter, or replace the fuel level sensor, the module can be disassembled.

To disassemble the fuel module and replace parts, remove it from the vehicle. (see here)

Disconnect the fuel level sensor wire block from the cover

Remove the fuel level sensor by sliding it in the direction of the arrow

Fuel level sensor 1 – resistor; 2 – slider; 3 – sensor wire block; 4 – float; 5 – float lever

Using a screwdriver, press out the three plastic clips...

...and remove the glass from the fuel module body. Here is a fine fuel filter (housing) and a coarse mesh filter

We disassemble the module in order to replace the filter

The main thing to remember: first disconnect the brown connector. Then remove the level sensor by unfastening the clamp with a screwdriver.

Similar clamps hold the top cover. Having removed it, disconnect the white connector (see photo). How to remove the lower part of the module is discussed in the previous chapter. But you will have to tinker with the nozzles: when putting them on or removing them, the fittings must be held above the steam.

No one was able to achieve results right away.

Instead of standard pipes, black, shiny and beautiful, you can buy corrugated hoses from a VAZ-2110 car. This replacement is proven.

What is the best way to deal with the flask?

On the Lada Largus, the fuel filter is a flask containing paper. This flask is not sold separately and cannot be replaced. But it can be cut to remove the filter element completely.

Fuel filter housing

At the last step, both halves are glued together, and drying is done under pressure (on ties).

For gluing, use any petrol-resistant sealant.

So, we have an “empty” filter housing that is being installed in place. After assembling the module, it can be used, but there is a condition: after 1000-2000 km the module will have to be replaced. Follow our advice if the engine has run for 150-160 thousand and you don’t feel sorry for it anymore.

What not to do!

It would seem that you can drive for a long time with a cleaned bulb, you just need to insert a new filter into the fuel line. This is usually done by taking a filter from Renault Logan (phase 1).

Fitting the filter into the line under the hood

It turns out this:

• If the flask is empty and an “external” filter is added, the engine starts and stalls after 2-3 seconds;
• If the flask has not been cleaned, adding a new filter is useless: the load on the pump increases, and that’s all.

Let the reader draw his own conclusions.

Alternative option

Below is a flask that looks almost the same as the original Lada Largus fuel filter.

JS Asakashi brand components

This flask can be installed instead of the standard one. You just need to shorten the fastening elements (tubes) by about 20 mm. We were talking about filters for Nissan cars:

• JS ASAKASHI FS22001
• JAPANPARTS FC-130S
• PATRON PF3924

Largus is equipped with Magnetto Wheels

The manufacturer installs 15-inch versions on the Lada Largus, which are supplied by the Magnetto Wheels corporation. Such products have conventional parameter markings in the form: “6×15/4×100 D60.1 ET50”.

Now let's decipher it in parts:

• “6” characterizes the width of the product in inches;
• “15/4x100” - here we have: 15-inch with 4 attachment points to the hub and a distance between the centers of the holes for fasteners equal to 100 mm;
• “D60.1” denotes the diameter of the hole in - the amount of overhang, which in our case is 50 mm.

The owners claim that Logan wheels are perfect for LADA Largus. Their parameters are as follows: “5.5×14/4×100 D60.1 ET43”. To complete such wheels, you will need to purchase 185x70xR14 tires.

When to change

The fuel filter of any car never lets the motorist know that it is dirty.

It is important to monitor this unit, occasionally checking its condition, and change it in time. Due to the specificity of its design, the Largus fuel filter is simply endowed with a “heroic resource”

According to the manufacturer, the filter element together with the fuel pump are designed for the entire service life of the car (about 160,000 kilometers). However, is this really so? Judging by practice, no.

Prototypes of the Lad Largus and their closest relatives, the Renault Logan, which have already traveled a considerable mileage, showed not only a longer service life of the engines (up to 300,000 kilometers), but also a completely different service life of the models’ fuel filters. Considering the general statistics, we can highlight the following:

• the “mesh” of the fuel pump, which passes gasoline after the coarse filter, or the fine filter can last no more than 30-45,000 kilometers;
• the main fuel filter has a service life of 80-120,000 kilometers, and as noted earlier, it changes along with the fuel pump.

Auto repair specialists recommend that every Lada Largus owner remove the fuel pump and check the degree of filter contamination every 20,000 kilometers. It is advisable to carry out an unscheduled inspection if:

• slight loss of traction;
• slight decrease/increase in fuel consumption;
• problems with the fuel system.

Important! The main difference between the fact that it is the fuel filter that is dirty is the gradual manifestation of the symptoms presented above. With other breakdowns, it is usually sudden.

Design and principle of operation

An engine, similar to a living organism, is able to “live” for a long time only on the condition that it consumes pure raw materials for its functioning. In terms of the fuel system, the fuel filter is responsible for organizing the purity of the gasoline entering the car engine. This part, simple in structure, performs functions of great importance for any transport. In particular, this Lada Largus unit allows:

• prevent large fractions from entering the injector and cylinders along with gasoline;
• filter out a considerable amount of small fractions also present in the fuel;
• extend the service life of both the engine and the entire fuel system.

The design of the fuel filter in the Lada Largus is very interesting and unusual for a model from AvtoVAZ. The fact is that fuel filter elements, or rather, two of them, are built into the fuel pump. The last part contains fine and coarse filters. Together with the fuel pump, both filters are a non-separable design that can only be replaced as an assembly. Taking this feature into account, the manufacturer made the fuel filter in the model very high quality and durable in terms of operation.

Structurally, the fuel filter and fuel pump on the Lada Largus are made quite complex, so we will not consider its individual elements. Despite this, following the example of the photograph below, which shows the location of the filter, any motorist will be able to determine the degree of its contamination, but already on his car.

Largus fuel filter: where is it located and how to replace it? Lada Largus

Probably every second car enthusiast knows that even in times of rapid progress, ideally clean fuel has not yet been invented. The most difficult situation with gasoline is observed in the CIS countries. Diluted or simply low-quality fuel fills more and more gas stations, so the motorist must monitor the condition of the engine and fuel filter on the Largus independently.

General information about the fuel filter

What is considered important in this system is the filter element, which cleans the fuel entering the injector or carburetor. The interesting thing is that this small unit, when used correctly, can increase the service life of the motor by up to 30%. If you do not promptly replace the fuel filter when it is dirty, rapid wear of the injection system is possible, which will lead to disruption of fuel injection and a decrease in engine power.

Why is this node needed?

Simple in structure, the fuel filter on the Largus performs functions of great importance for literally any car. This Lada unit:

• Prevents large particles from entering the injector or cylinders along with low-quality fuel.
• Filters out fine sand, which is also found in fuel.
• Extends the life of the fuel system and engine.

Fuel filter device

The design of the fuel filter on the Largus is interesting, as for a car model from AvtoVAZ. The design has two filter fuel elements that are installed in the fuel pump system. Fine and coarse filters in tandem with a fuel pump are a one-piece design. This means that in the event of a breakdown, in most cases the unit is completely replaced

Taking this feature into account, AvtoVAZ made the fuel filter for Lada Largus reliable, high-quality and with a long service life

The design of the fuel filter and fuel pump on the Lada Largus is complicated, so there is no point in considering individual elements. But, despite this, even an amateur motorist will be able to visually determine the degree of contamination.

Part replacement

How to change the fuel filter on Largus? To carry out repairs, you will need to disassemble the entire fuel pump system, which, of course, is not worth doing. This procedure is not only financially expensive, but also time consuming.

When to change

You will not be able to know if the fuel filter is dirty unless you regularly check its integrity and condition. Due to the specific design, the fuel cell on Largus is endowed with a “heroic resource”. As AvtoVAZ says, fuel filters together with the fuel pump are designed for the entire period of operation of the car, that is, about 160 thousand kilometers. But is this true? Based on practical experience, no.

Considering the average statistics, we can highlight the following:

• a mesh filter in the nozzle of the injection system, which passes fuel through itself after primary and fine cleaning, can last no more than 30-45 thousand kilometers;
• The main fuel filter has a service life of 80-120 thousand kilometers.

Experienced car repairmen advise every Largus owner to dismantle the entire fuel pump module and check the level of filter contamination every 20 thousand kilometers. The check is also carried out if:

• slight loss of traction;
• problems with the fuel system;
• reduction or increase in fuel consumption.

The main difference between the fact that it is the fuel filter element that is dirty is the gradual appearance of the symptoms described above.

Lada Largus: a box with a secret

"Lada-Largus" is a copy of the "Dacia-Logan MCV", known in some European markets under the Renault brand. The localization of production at AVTOVAZ has so far affected only small things. The most noticeable parts are the radiator grille and the nameplates on the rear doors: they feature the branded boat and the familiar name LADA. The machine's components were borrowed from other Renault models - Logan, Symbol, Megan (ZR, 2008, No. 2; 2010, No. 4; 2012, No. 3).

When replacing spark plugs on a K4M sixteen-valve engine, the main thing is not to drop the fasteners of the individual ignition coils: the bolt easily slides off the head and disappears into the abyss between the intake manifold and the valve cover. If you don’t catch it, it can later cause trouble by shorting out electrical circuits or rubbing holes in the plastic manifold.

To remove the connector from the individual ignition coil, press down the latch tab. If there is a lot of resistance, slide the connector onto the coil, selecting some play, and then press. To remove the connector from the individual ignition coil, press down the latch tab. If there is a lot of resistance, slide the connector onto the coil, selecting some play, and then press.

On the eight-valve K7M (they also install such ones) the candles are in full view. But don’t rush to rejoice: before you take the spark plug wrench, remove dirt from the bottom of the spark plug wells, otherwise it will certainly fall into the cylinders. First, we separate the stuck together grains of sand with a thin, hard brush or piece of wire, and then blow them out with compressed air. Perhaps, in this discipline there is complete parity between “different-valve” engines.

It is easier to change the oil in an eight-valve unit: if you remove the exhaust manifold protective cover by unscrewing three nuts, you can hook onto the filter housing from under the hood. And even a chain puller. But it is advisable to purchase an original cup puller - it is relatively inexpensive, and it is much more convenient to work with (and you don’t have to remove the casing). The drain plug is for an 8 square socket, have this key ready in advance. Access to the plug is possible through the slots in the standard protection of the engine compartment.

The oil filter (shown by the arrow) is hidden away. Even if you have a puller, act carefully so as not to damage the communications. It is better to immediately cover the engine number (in a circle) with anticorrosive. The oil filter (shown by the arrow) is hidden away. Even if you have a puller, act carefully so as not to damage the communications. It is better to immediately cover the engine number (in a circle) with anticorrosive.

The approach to the filter on a sixteen-valve valve depends on the presence of an overpass or inspection ditch. If these amenities are available, then it is better to remove the protection by unscrewing the six bolts and enter from below. No - we get up from above, removing the protective screen of the fuel rail. In any case, there is nothing to do here without a filter cup remover, since the communications of the power steering, generator and air conditioner greatly interfere. Compared to Priora, this option receives a well-deserved two in the final protocol.

Replacing the coolant is no easier, since the system does not have drain plugs. There is nothing left to do but remove the lower radiator pipe, risking getting burned by hot liquid (there is more escape when it is hot) or inhaling toxic fumes (from the trough they “smell” much more strongly than from the narrow neck - but how to get into it?) . To compensate, there are fittings to remove air from the filled system, but this is little consolation.

PRODUCT NUMBER ONE

You can probably handle replacing the air filter on both modifications. Considering that the cover is attached with self-tapping screws, we recommend that before installation you feel for the entry of the thread: after turning the fastener counterclockwise, catch the gap and only then turn it clockwise. This way it will be possible to preserve the thread, and therefore the body itself, for many years.

Neither a fuel nor a cabin filter is provided - a huge minus. If you can live carefree without the first, as the experience of using Logans shows, up to 200 thousand km, then sometimes you can’t do without the second on our dusty roads. “Garage workers” propose to embed a filter from a Nissan-Micra (or Renault-Modus) into the body of a standard heater, cutting through a window 150 × 38 mm (ZR, 2008, No. 9). Most likely, this technology will also take root at AVTOVAZ official dealers. But why doesn't the plant improve the heating system?

Saving on a cabin filter looks ridiculous. The plane in which the window must be cut is shown by an arrow. What prevents you from doing this at the factory, even if you close the hole with a plug? Saving on a cabin filter looks ridiculous. The plane in which the window must be cut is shown by an arrow. What prevents you from doing this at the factory, even if you close the hole with a plug?

If you decide to install the filter yourself, take your time: move the passenger seat back, lie down comfortably on the floor and use a shoe knife (or better yet, a piece of hacksaw blade) as carefully as possible so as not to accidentally make a hole in the heater radiator. And protect your eyes from falling chips!

PRODUCT NUMBER TWO

You are unlikely to change the timing belt yourself, since to do this you need to have mandrels to align the crankshaft and camshaft in the only correct position (this applies to a greater extent to the K4M), as well as hang the power unit and remove the right support. None of this is easy, so most owners find it easier to turn to specialists.

God forbid you start replacing the timing drive on a sixteen-valve engine without such mandrels (shown on the left side of the photo). The fact is that there are no keys or pins in the connection of the shafts with the pulleys.

The automatic serpentine belt tensioner is only available in the version with air conditioning (applies to both engines). To remove the old belt, first dismantle the right side panel of the engine compartment and move the tensioner to the side, using a 15mm wrench to grab the roller bolt. We check the bearings of the mounted units and the rollers themselves - support and tension: you should not feel the balls rolling.

The drive of mounted units on the K7M (pictured) is no different from that on the K4M. Moving the tensioner clockwise by the roller bolt, insert the pin into the holes on the sectors (shown by arrows).

SEE THE ROOT

It is easier to replace headlight bulbs on the right. The battery prevents access to the left headlight; it is often better to remove it. Especially if your hand is calloused and your fingers are not like a pianist’s. And yet, in most cases, it is possible to fasten the spring latch of the H4 lamp, although not the first time. Access to the turn signal is more or less acceptable.

To replace the fog lamps, you will have to lie on the ground and unscrew the corner screen fasteners under the bumper. The work is dirty and terribly unpleasant, especially in the slush. The question is, what prevented you from providing technological windows in the mudguards, as is done on many French cars?

To replace the bulbs, the lantern must be removed, and you will suffer with the tightly tightened upper fastening knob. The board with lamps is secured with three latches.

To replace lamps, headlights must be removed. It seemed that ) had provided such a scheme for attaching the lights, which one could reluctantly come to terms with - to dismantle it, you need to unscrew two plastic thumbs. But the top one turned out to be tightened to death; even with cobra-type pliers they could not touch it. Fortunately, at the end of the head there was a recess for Torx-30.

“Alas, the “casket” did not open as easily as we would like. Poor access to the oil filter let us down, but most importantly, the rear optics were disappointing. It would be a good idea for the plant to standardize the tightening torque of the flashlight fasteners so that we don’t break our fingers on it.”

Part replacement features

Replacing this part is not so difficult if you know where the fuel filter is located on the Largus and how to carry out the repair correctly

It is important to note that even an amateur motorist can perform the replacement procedure, since the whole process is very simple. Replacing the filter does not require any serious preparation, except for the following measures:

• It is best to replace the filter element in a spacious workshop, where the car can be parked on level ground, securely fixing it with a handbrake or a wheel stand;
• prepare in advance a standard car repair kit: several screwdrivers, a set of keys, rags and gloves;
• buy a fuel pump assembly or a separate fuel pump “mesh” (for example, the same part will do, but only from Renault Logan).

The procedure itself takes no more than 30 minutes, of course, if you do not want to completely disassemble the fuel pump system and try old-fashioned methods to clean the fuel filter. Replacing the part with a homemade filter is considered a bad idea. Also, this should not be done because incorrectly cleaning or assembling the fuel pump will cause serious damage to the entire Lada Largus fuel system. Is it worth it? Most likely no.

Part replacement

Replacing the fuel filter on a Lada Largus is not so difficult if you know where it is located and how to carry out the repair correctly. It is worth noting that even an amateur car repairman can carry out the replacement procedure, since the whole process is extremely simple. The event does not require any special preparation, except for taking the following measures:

• Place the car in a reasonably spacious and level place, securing it securely (handbrake, wheel stands, etc.);
• prepare a basic car repair kit: a set of keys, a pair of screwdrivers, rags and gloves;
• purchase a fuel pump assembly or a fuel pump “mesh” separately in advance (for example, a similar part from Renault Logan will do).

The replacement procedure itself takes no more than half an hour, of course, if you are not going to completely disassemble the fuel pump and try to clean the filter using “old-fashioned” methods or replace it with a homemade one. Moreover, it is undesirable to do this only because by incorrectly cleaning or assembling the fuel pump, you can provoke more serious damage to the fuel system of your Lada Largus. Is it worth it? Most likely no.

So, the algorithm for replacing the fuel filter is as follows:

1. Remove the rear sofa cushion and lift the plastic hatch underneath. For ease of work, you may need to move the carpeting to the side.
2. Having first disconnected the battery, bend the tab on the fuel pump connector and disconnect it.
3. Next, you need to connect the battery and start the engine. The running engine should run for a few seconds and then stall. After this, de-energize the system again by disconnecting the battery terminals.
4. Disconnect the fuel pipe and unscrew the fuel pump retaining ring counterclockwise. Using a mounting spatula will help make this step easier.
5. After completing the previous steps, the fuel pump module can be removed. If necessary, replace the mesh filter or the entire fuel pump. After replacement, it is necessary to reassemble the entire structure in reverse order.

Important! It is not advisable to disassemble the fuel pump to replace the filter. This practice may negatively affect the condition of the entire fuel system in the future. It’s better not to skimp and replace the entire fuel pump

As you can see, replacing the Lada Largus fuel filter is quite simple if you know its design features and location in the car. We hope the material presented above was useful to you.

Removing the fuel module

We will perform all the steps as if we were trying to replace a fuel pump:

We tilt the sofa cushion and remove it. We lift the plastic hatch and move the carpet forward. Remove the round cover from the hole;

Getting rid of unnecessary details

Understanding electricity

First - the pipe, then - the clamp

By removing the module assembly, you can replace the mesh filter. Be careful not to lose the O-ring installed between the module and the tank.

Replacing the filter mesh

On the Lada Largus, the coarse fuel filter is a removable mesh in front of the pump. Replacing it will be simple:

We snap off the glass latches (3 pcs.);

Let's start disassembling the module

The very first element in the fuel tract

Installation of all modules and components is carried out in the reverse order. If the mesh is not badly damaged, it can only be washed and dried. Car chemicals based on xylene or ethoxylated alcohols will help.

Vehicle Specifications

In this regard, all the cars turned out to be different from each other, so there is something to compare here.

Review of Largus and Duster

The power plants of the two cars have the same volume, but there are differences between them. Both cars are budget, so the volume of 1.6 liters (with a slight difference of a few cubic centimeters) is standard. Duster wins due to its greater power; it has a maximum of 114 horsepower. These horses are clearly not enough for a full-fledged SUV, especially considering that the latter have a power of 300 hp. With. and higher is a common indicator, and engine volumes are much larger.

The Lada Largusa has an engine power of only 87 hp. s., but on the road the difference of 30 horses is practically not felt, given the different weights of the cars, and the acceleration is approximately the same. The torque of Duster is 156 N/m, and that of Largus is 140 N/m. From this we can conclude that the engines have many similarities, but Duster’s power unit is still adapted for off-road driving

Even taking into account the version of the Largus Cross with increased ground clearance, it should not be regarded as an off-road conqueror

The transmission of two cars is manual, five-speed. However, Duster has clearer manual transmission shifts. In addition, the “French” boasts a full-fledged 5-band automatic transmission.

Logan or Largus

Both have front-wheel drive with MacPherson strut suspension. Logan has a gasoline engine with a capacity of 73 horses. And the station wagon version additionally has an 84-liter diesel engine. With. The Lada does not have a diesel engine and is not expected to have one, but it has two gasoline engines. In addition to the above, there is also a more powerful 102 hp power unit. With.

Article number of the branded fuel filter Lada Largus

Fine and coarse fuel filters for Lada Largus are part of the fuel module. Officially, the manufacturer allows replacement of the glass only as an assembly. Therefore, neither the fine filter nor the mesh have their own article numbers and are not available for retail sale. Therefore, it is impossible to purchase original new consumables separately, and they are expensive when assembled with a module.

The original fuel tank for the Lada Largus with an 8-valve engine has article number 172024388R. A similar unit is used on cars with a 16-valve engine. A branded fuel module costs from 18,000 to 30,000 rubles.

Since the cost of the original module with fine and coarse filters is high, drivers resort to purchasing analogues. There are quite a lot of good options among them. The table below shows the best alternatives to the original fuel cup.

Table - Analogues of the fuel module for the Lada Largus car

Despite the lack of original fine fuel filters on sale, wanting to save money, car owners adapted consumables from other cars for the Lada Largus. The table below shows filters that are suitable for restoring normal operation of the module.

Table - Fine fuel filters for the Lada Largus car

Filter meshes from some other cars are also suitable for Lada Largus. The table below presents third-party manufacturers whose consumables are recommended to be installed when the coarse mesh is clogged.

Design of the fuel filter flask in the pump

What is outlined in the figure is the fine filter. Through mesh 2, fuel enters the pump, then it enters container 3. This container is connected to the ramp through the upper fitting and pipe. Connection 1 is also an important element, since it is connected to the return valve.

Fuel module disassembled

The return flow valve is built into the lower glass, and it allows you to relieve excess pressure.

By the appearance of part 3, you can always assess the degree of filter clogging. It's a pity that the container is non-separable. Unfortunately, it is pointless to look for the article number for part 3: the fuel filter on the Lada Largus is replaced as an assembly with the pump.

Lada Largus fuel filter replacement interval

According to the official regulations, the Lada Largus fuel filter has a resource equal to the entire service life of the car. In other words, AvtoVAZ says that the fuel filter does not require replacement and is designed for the entire service life of the car. And this is at least 160 thousand kilometers.

But from the experience of owners of such cars, we can conclude that the coarse filter begins to become clogged at 30-40 thousand kilometers, and the fine filter - at 80-90 thousand kilometers. In other words, the fuel filter on the Lada Largus really can withstand long mileage, but I would recommend changing the fuel filter much earlier.

The optimal replacement option is considered to be 30 thousand or 24 months. Believe me, with our quality of fuel this will be the most correct option. It’s both good for the car and easy on the pocket. When replacing the fuel filter, it is not necessary to drain gasoline from the Largus tank.
