How to change the fuel filter by car. How to replace the fuel filter replace fuel

the main / Advice

Replacing the fuel filter is a problem with which, for sure, each driver has come across. This element of the car sifts all the garbage, rust particles, dust and does not allow them to get into the fuel system highway. And since the components in it have a very small cross section, then the falling dirt would quickly lead them into disrepair.

When is it obvious that the fuel filter is needed?

The filtering system performs two degrees of purification: rough, removing all major particles, and thin. Installed between the engine and fuel tank. Experts advise the replacement of filters every 60 thousand kilometers. After all, their accuracy leads to very serious consequences, for example, an additional burden on the fuel pump arises, and it may fail much faster. Also, the clogging generates incorrect operation of the engine, because the fuel supply to the system does not occur as if it should.

Thus, the car reads troit, it stalls, and sometimes it may not start at all, and incorrect gear shift occurs (in the case of automatic transmission, i.e. automation ceases to correctly interpret the engine commands to switching and performs their inadvertent or reacts at all). But not to bring the situation to such a critical moment, you can check whether it does not need fuel filter in replacement. At low speed, sharply press the gas pedal, if the car does not accelerate either there are jerks, it means that the filter replacement is necessary.

How to change the fuel filter - buying a new element

When this item is selected, you must pay attention to the following parameters:

  • filtration level. If it is insufficient, and large particles still penetrate into the system together with the fuel, it will very quickly lead to the engine breakdown;
  • the area of \u200b\u200bthe filtering element, as well as the presence of a rubber seal, which covers the input to the filter itself. In the event that there is no one, this item will be very problematic to replace.

Depending on the fuel system filters thin cleaning are divided into:

  • carburetor, permissible degree of purification of 15-20 μm (particles of smaller size will be held in this system, but will not harm the fuel delivery system in the motor);
  • injector, smaller degree of cleaning, 5-10 μm (in such systems requirements for maximum size Permissible contamination above, i.e. The injector can be clogged from larger particles, so the holes in the filter is less);
  • diesel, capable of holding not only very small solid particles (less than 5 microns), but also to remove moisture, and this is very important for.

When buying it is important to specify the seller the brand and the year of release your car to choose the right filter. For the most part, if there was no product specifically for your case, you can choose something interchangeable. But there are cases when it is impossible, so familiarize yourself with this information in the manual for your transport facility.



How to replace the fuel filter - instruction for independent

Of course, you can contact the specialists who replace this detail for ten minutes. However, if you want to save a little, then make a similar procedure yourself quite real, and now we will tell you how to change the fuel filter. To do this, it is necessary to determine its location, most often it is under the hood, at the top of the engine (characteristic of diesel cars) But there are some models in which you can find it in a tank next to the fuel pump (this is a feature of gasoline cars).

Then you should pull out the fuse from the fuel pump and wait until the engine is stroke, so you hover the pressure and keep yourself from pouring fuel. Now turn off the negative terminal of the battery, in order not to be marked, and carefully examine the method of attaching the old fifteer to the fuel line (intake mount and graduation), it can be baratic bolts, and latches, the main thing is to remember, in which sequence everything was in order to also establish and new element. Mark visually and location of sealing washers and rubber gaskets.

Now wrap the old filter with a rapid, so as not to flow fuel, and remove it, after removing it from the bracket, which supports it in a bunch with a top-core. Install the new item on the bracket exactly in the same position, in which the old one was located (sometimes on the filter you can find a tip in the form of an arrow, how to insert it into the socket). With the help of new fasteners (they are included in the kit), connect the fuel line, after checking the integrity of all its lines, in case of detection of a defect (cracks, inflection) it is necessary to replace it.

It remains to insert the fuel pump fuse, connect the terminal and start the engine, it does not always work from the first time, since the pressure was lowered. In the question, how to replace the fuel filter, the safety technique should be very much attention. If you smoke, then give up this harmful habit while working. Make sure that the room is well ventilated, and do not forget to thoroughly wash off the fuel from the skin of the hands. Also, would not hurt just in case stocking and fire extinguisher.

Any, even the most high-quality automotive fuel - be it gasoline or diesel fuel, contains a large amount of extraneous impurities that cause great damage to the engine. And to minimize this very harm, extend the life and perfect operation of the engine, in every car there is a special fuel filter. But he also needs continuous care, but the main thing is to be regularly replaced. Today we will tell how the fuel filter is replaced.

The filtering device is the most important part of the fuel system. It filters and neutralizes rj / dirt particlescontained in the capacles where fuel is stored and transported. In addition, it "relies" the working mixture from the inclusions of water formed on the surface of the gas tank. Due to the chemical processes occurring during the operation, the impurities fall into fuel, and then in the power unit, killing it. The main purpose of the filter element is the destruction of water, since its presence in the working mixture does not lead to wear, but to the "death" of the motor. The filter element allows the power unit to work clearly, without failures.

Views fuel filters

Varieties of filter elements

Depending on which vehicle is focused on which the vehicle is oriented, it is put on a specific filtering device. We will tell about them a little more.

Filter for carburetor

Since the carburetor engine is distinguished by low pressure, the working mixture enters the motor using special rubber hoses. Exactly they "crashed" the filter element. This can be a plastic product or metal. The product has 2 tubes (intake / release). For the purposes of greatest reliability, hoses are fixed using special clamps.

Filter for the injector

Feature of this element - transfer key function to central the electronic unit . The working mixture enters the engine under high pressureAnd this assumes the presence of the highest quality metal fuel lines. If we talk about the fuel pump itself, it is made of steel or other particularly solid metals. Threaded elements are used as connectors.

Filter for diesel

Diesel engine fuel is considered the most "dirty" Of the existing today, it implies an increased purification from all sorts of impurities. Paraffins are carrying the greatest danger of internal elements of the car. They transform into crystals, clog the main clearances from the details. Therefore, two filtering devices are applied to vehicles operating on the diesel market - the main thing and additional. This allows you to clean the fuel from unnecessary impurities by 100%.


Varieties of filters

In addition, filtering elements installed on vehicles, differ in the following characteristics:

  • degree of cleaning (coarse / thin);
  • view of the casing (metal / plastic);
  • operating pressure (high / low);
  • type of fuel (die / gasoline).

Where is the filter in the car

Before moving to the question, how to replace the fuel filter, you need to figure out exactly where it is located. Guided by the task that is set before the filtering element, the most logical location of its location on the way from the gas tank to the engine.

And the location of the filter y different marks Machines are the most different.

For example, Japanese manufacturers make a filter in one case with a fuel pump. Install the device immediately in the gas tank. But this design is characterized by two substantial disadvantages:

  • replace the fuel filter only in the car service;
  • often, behind the breakdown of this device immediately should replace the node completely.

If we talk about the domestic automotive industry, then on the VAZ "classic" the filter is located under the hood, it contributes to a convenient control over the state of TF and its fast replacement. On later lada cars The filtering device "hid" into the back beam, under the bumper.

Well, if you say generally about the most popular location points of the fuel filter, you can list the following:

  • rear bumper;
  • in niche on the bottom;
  • in fuel tank;
  • motor compartment or in the open space.

Separately (on the frame), a separator / FPO can be installed in the vehicle.


Fuel filter location

The frequency of replacing the filtering device

A lot of conditions affect the working resource of the filter element: the quality of the fuel fuel, the technical condition of the fuel system, operational conditions vehicle etc.

  • the nozzles are clogged and oxidized;
  • rust is formed;
  • used low-quality fuel;
  • the filter mounted filter himself was different.

During the operation of the car inside the rubber / copper tubes in fuel system Flame is formed, and oxides and rye accumulate on metal elements. So, the more years the car, the faster its filtering device is clogged.

Therefore, not only the mileage on the speedometer should be a reason for replacing the fuel device.

Symptoms of the need to replace TF

The degree of contamination on filters with a transparent case is easy to install visually. The filter that needs to be replaced, darkened, and the fuel falling into it also loses the transparency.

If another species filter is installed in the car, the following features will be replaced by the replacement signal:

  1. The car began to twitch while driving (it is especially felt when lifting).
  2. The engine is constantly stall.
  3. Increased fuel consumption.
  4. Reduced power power aggregate.

From the pouring of bad fuel to the tank (gasoline / powered) is not insured by any motorist. As for the quality of the filtering element itself, here everyone chooses the product itself in accordance with the necessary characteristics and its own financial capabilities.

BUT! By buying a filter element, it is reasonable not to rush for the cheapness, but to purchase original filters of proven manufacturers.


Replacing the fuel filter

Replacing the fuel filter

The main procedure for performing actions when replacing TF on most types of auto is similar - at the end of the operation of the filter element, the old device is removed, and it is put instead new filter.

the main distinctive feature of U. different engines - This is the location of the filter itself. And on this depends the complexity of work and other details

To dismantle / install TF from cars with different types Engines may require a special tool and fixtures. They must be prepared in advance. Next, we will tell you how to change TF for each specific type of engine, explaining how to remove the old and put a new filtering device.

Replacement TF on the carburetor

W. carburetor Engine The filtering device is usually located under the hood. It is made of plastics / light alloy metals, and its installation will be simple and understandable for everyone.

First, you need to remove the clip on each side, then dismantle the filtering device itself. By putting a new TF, it is extremely important to put it correctly, not confusing the direction (inlet / release). So that the car owner is easier to navigate, there is an arrow on the housing, which when installing should look at the benzobac.

Putting the clips to the place, it is necessary to download fuel with a gas station handle. If at this moment a light whistling will be heard, therefore, tightness is impaired. Metal clamps will help ensure reliable fasteners.

Important! The fuel device should not come into contact with the lid on the head and the block body.


Replacing the filter on the injector

Replacement TF on the injector

The flow of the working mixture into the injector motor cylinders occurs under high pressure, and therefore TF for such motors make metal with threaded fasteners on the connections. There is a TF injector in motor compartment Or under the bottom.

  1. To begin with, the pressure in the system should be reduced, for which in the safety unit, which is located at the gear lever, it is necessary to remove the average (usually responsible for the functioning of the pump).
  2. Then you need to start the engine and wait when it stalls (usually, not more than a minute).
  3. Next, using the appropriate tools, the old filter is dismantled and install new. Here the arrow should show in the direction of fuel movement.

Having finished work, you need to put a fuse in place. After that, try to run the power unit.

Surely, the 1st attempt of the result will not bring, since it takes some time to stabilize in the system of working pressure.

In conclusion, tell me how to change the filter on the machines with diesel enginewhich are extremely sensitive to the characteristics of the fuel poured. Nozzles are clogged from a significant amount of impurities, and this affects the correct operation of the power unit.

We have already mentioned above that diesel cars Installed 2 filters (pretty / fine cleaning). The second, usually, it is necessary to change after 10-15,000 km of mileage. It is located in the front part of the car, and in order to get to it, it will take to dismantle the wheel with a hide. After that, you need to make the following actions:

  1. Twist the tray.
  2. Separate the chip from the water meter.
  3. Remove the fittings by clicking on the buttons located on the back wall.
  4. Remove the water level meter and the cork below.
  5. Supply dismantled spare parts with new details that provide tightness (rubber gaskets / washers are supplied with the filter).
  6. Put the water meter with a plug on the installed filter device, then put it on the machine.

When installing should not be powered along the water meter - all work is required to be carried out with maximum accuracy.

Check out the assembly, the color marks on the filtering device and the color of the fittings are helpful - they should coincide!


Replacing the filter on the diesel

And so that at the end of the work the car began, before installing, you need to fill the new TF diesel. To exile excess airs, you can bring the starter for 5-7 to the starter, pre-slightly squeezing each nozzle. For 2-3 similar procedures, small bubbles appear near them. Pulling the nozzles from the driver's side, you need to re-execute several starter rotations. After that, you need to hold the remaining. These actions will help to start the car engine.

Do not forget about security

  1. Before replacing the elements of the fuel system, it is necessary to turn off the mass on the battery - it will be possible to protect against the emergence of a random spark and flammable ignition.
  2. It is better to produce work at moderate temperatures. If you need to replace the summer in the heat, then you need to avoid direct sunlight.
  3. Smoking and use open fire in the process of work is categorically prohibited.

Should not be negotiated to clean the fuel - This reduces the life of the power unit!

It is worth the filtering device is not so expensive to save on it, and its replacement will not require large skills and knowledge. Therefore, it makes no sense to save on it. Since the replacement of the piston or overhaul of the engine will cost where.

If the car engine has begun to work unstable (stuff, told, badly start), then there may be several reasons for this, one of them is the fuel filter failed. However, to make sure that this unit fell out of order, it is necessary to reliably determine the cause unstable work Engine. If the reason for the breakdown is in this detail, then the fuel filter replacement should be replaced by new aggregate, taking into account the features of different filter models. You can do this in the car service, or on your own. How to choose and independently replace the fuel filter, we will look below (see video "Replacing the fuel filter on the VAZ 2110, 2111, 2112" below).

When should I change the fuel filter?

Automotive experts advise to perform the replacement of fuel filters after 60,000 km of run, since it is by this time their sufficient clogging occurs. The car, of course, will be able to ride even long enough and on the clogged filter, however, in this case, the load on the fuel pump increases, the service life of which begins to decrease. In addition, the engine will start giving failures due to incorrect fuel supply. To reliably establish what the fuel filter broke (scored), it is necessary to do the following:

  • Dispersed cars at low speed;
  • Click as cracked on "gas".

In the event that the car engine started working with jerks or refuses to accelerate, then the reason for the unstable operation of the power unit is in the filter, that is, the fuel filter replacement is inevitable.

How to choose a new fuel filter for the car?

Key options. The selection of the fuel filter should be performed, given the following key parameters:

  • Taking into account the size of the filtering level: it depends on it, which, largest particles should be filtered. If you select a low-filter filter, then large particles will penetrate the fuel and, in the sooner, the engine will be displayed.
  • Consider the area of \u200b\u200bthe filtration element, the clogging speed will depend on it: the greater the area, the longer the filter is served, and vice versa;
  • The presence or absence of a rubber seal covering the filter inlet: filters without a sealing is more complicated.

Cleaning level. It is also necessary to distinguish fuel filters by cleaning level so that the element replaces is performed correctly. So, there are carburetor, injection and diesel fuel filters. Each type of engine is the corresponding fuel filter.

  • For carburetor systems, the cleaning level is ranging from 15 to 20 microns. Everything that is smaller will fall into the fuel system, however, no harm to the engine will be represented;
  • For injection systems, the cleaning level is ranging from 5 to 10 microns.
  • For diesel systemsThe cleaning level is within less than 5 microns. In this case, not only particles in fuel are filtered, but also water.

Of course, buying a new automotive fuel filter, you need to know the brand of the old filter, as well as the time of its release. As for the replacement of the filter to a similar one, but another brand, then here you need to carefully examine the possibility of this operation in the instruction manual.

How to change the fuel filter yourself?

Before starting work, it is necessary.

The direct replacement of the fuel filter on the car begins with the definition of its location. The most common version of its location is under the hood, on top of the engine (almost all diesel engines).

W. gasoline engines The fuel filter is located in the immediate vicinity of the fuel pump.

1. You need to start the engine engine.

2. Immediately after the filter is found, it is necessary to dismantle its fuse, and wait until the engine itself is to fall so that the pressure fell, and the fuel does not start pour out.

3. Then remove the terminal from the battery with the "-" sign (in order to prevent fire).

4. After that, disassemble the scheme of how the dismantled filter is mounted in the fuel engineering system. Remember the sequence of the location of each of the attachments, as well as the washers and gaskets.

5. Removing the unit from the bracket, and wrapped it with a rag, you need to pull it carefully (wrapped rack will absorb oil, when leaking it).

7. Using new fasteners, connect the filter to the fuel engineering system.

8. On this, the replacement of the fuel filter to the new item is completed. It remains only to put a fuse, taken out at the very beginning of work, at its former place.

9. Connect the back negative terminal and start the engine.

Note that an attempt to start the motor from the first time is usually not possible, since pressure should be recovered during dismantling.

To ensure normal conditions for the car, it is always necessary to monitor the quality and health of the fuel filter, and also periodically replace this node. Often when conducting an independent regular maintenance Car owners forget about the need to replace the fuel filter. But in our conditions of dubious quality of gasoline and unforeseen contamination in the fuel mixture, such an error may cause a damaged health of the power unit.

IN different cars Fuel filters are located in different places, but they are always installed solely on the highway, in which the fuel gets from the tank directly in the combustion chambers. At some models, these filters are located under the hood, others - just do not exit the fuel tank. You can simply find out enough - it's only worth opening the instruction manual for your car.

The frequency of the fuel filter replacement by car

Each manufacturer has their own requirements for the frequency of the fuel filter replacement procedure. Some models can be replaced once by 60 thousand kilometers, others worth performing this procedure once a year. In fact, the more often you will change fuel filters, the better there will be the conditions of engine operation on your car.

Often replacing the fuel filter is performed after the driver feels certain malfunctions in the operation of the power unit. The engine begins to "hit", troop, badly start. All of these symptoms can be associated with a stuffed fuel filter and poor bandwidth of this device. Equipment replacement incentives may be the following:

  • the need to replace the filter by technical Regulations car maintenance;
  • damage to the filter, depressurization of the case or other deformations;
  • unscheduled fuel system maintenance and installing new filters in all cars;
  • diagnostics of the fuel system and malfunctional detection in the highway itself;
  • purchase a used car and the lack of history of its service.

In all these cases, it is worth replacing the fuel filter. The cost of this procedure will depend on the brand of your car, but often filters are not too expensive. It is better to give preference to the factory or recommended manufacturer of filter options to ensure the normal operation of the car in various conditions.

When operating the equipment that is not recommended by the manufacturer, you get certain risks that can lead to the loss of performance of the power unit. So it is better to overpay several tens of rubles and buy a good fuel filter. Then the replacement will be fully correct, you will not have to worry about the quality of the procedure produced.

We perform the replacement of the fuel filter with your own hands

If you are the owner domestic carwhich was produced until 2008, then you can count on quite simple replacement filter. To do this, it is enough to look under the hood, to find a transparent plastic barrel and replace it with a new one, squeezing the clamp on the rubber hose. It will not require special skills and special knowledge from the artist.

If you own modern car or foreign year of the last ten years of release, the fuel filter on your car has another appearance And not necessarily under the hood. For more efficient fuel purification, the filter is located directly on the fuel hose highway, can be fixed on the bottom of the machine or directly on the fuel tank. Its replacement is performed in the following stages:

  • disconnect the terminals from the battery to avoid the operation of the fuel pump and shock the current from the car equipment;
  • hold the nut that is responsible for the flow of fuel through the filter - it will help get rid of the constantly current fuel from the hoses;
  • unscrew the nut or clamp that holds the filter in its working position - the fastening system for each car is different;
  • next, press the two nuts of the fuel line fittings to which the filter is attached, and remove the old device;
  • install a new filter purchased in store in advance, make sure that the device is fully suitable for your car model;
  • screw the tightly retaining nuts so that the fuel filter does not fall off from physical influences;
  • open the gasoline feed using the nut, which was clamped at the very beginning.

On some cars, it will have to overlap the supply of gasoline directly at the outlet of the tank. This complicates a little problem. The location of the fuel filter on the bottom also requires looking Jama In your garage for replacement. In the same procedure, the filter change is nothing complicated. You only need to correctly perform the above steps.

Make sure that the gasoline when unscrewing the old filter did not hit you in the face, because it can cause unpleasant consequences. With the help of measured and thoughtful actions, you can easily change the fuel filter, install new equipment and get the highest quality conditions for the operation of the power unit in your car. For owners of new domestic cars We offer to see the following filter replacement video:

Let's sum up

The high-quality operation of the fuel filter is necessary for any car. It is important that the fuel takes place primary cleaning from all major particles that can harm the operation of the power unit. Therefore, it is necessary to monitor the high quality and performance of the filter to get the necessary conditions Works of equipment of the entire car. Change the fuel filters on time, moreover, this procedure will not be a long time and will not provide any trouble when performing.

If you forgot about the fuel filter, make it replace it right now. The car will definitely be grateful to you for the service and care, last longer and will not make unpleasant demonstrations. Tell me, have you had to perform an emergency replacement of the fuel filter on the road?

The work of the internal fuel depends on the quality of the incoming fuel. The low-quality fuel, the greater it contains various impurities. To clean the fuel from impurities serves as a fine fuel purification filter. The article covers, why you need to change it and describes in detail how the replacement is performed.

[Hide]

Why do you need to change the fine filter?

Any car in which various working fluids are used is equipped with special elements that serve to purify liquids from harmful impurities. The fuel system for cleansing the fuel uses a coarse and fine filter. During the operation of the car, it clogs and does not fulfill its qualitative functions. Therefore, it has to be periodically changed.

Gasoline contains abrasive particles that adversely affect work in the economy. On gas tank, carburetor and fuel pump are special meshes for fuel purification, but they are not enough for high-quality gasoline cleansing. They can delay only large particles.

Fine cleaning filters are intended for trapping small particles. They can delay the elements of size and 15 μm.

If it does not change the filter element on time, then it threatens the following problems during the operation of the car:

  1. The engine works with jerks, first they appear at high revs, and then when switching to low.
  2. The machine loses power. The contaminated element does not perform its functions, the fuel injection nozzles are clogged, the fuel system is clogged. Thus, an insufficient amount of gasoline enters the engine, which leads to a decrease in its power.
  3. Premature wear of lambda probes, spark plugs and accelerators. With poor cleaning, the fuel will not completely burn out, part settles on cylinder partitions, candles and pistons. As a result fuel mixture It is saturated with heavy metals and outsiders, and then falls through accelerators and lambda pridesmasters into the exhaust gas system, which significantly reduces the service life of parts.
  4. Increases fuel consumption. A clogged fuel filter does not affect the fuel consumption directly, but it is the cause of a reduction in car power. As a result, for overclocking the car to the desired speed, it is necessary to put pressure on gas more, which requires more fuel consumption.
  5. The car does not start. If you neglect the filtering element change, as the manufacturer requires, it can be reached that the engine does not start.

Filters differ in design and are divided into indispensable and folding products. Insecifications belong to disposable details.

The collapsible consists of a ceramic element and a mesh, which can be cleaned, washed and used several times. The cost of the collapsible filter is slightly higher than one-time.

Where is?

If the procedure for replacing the fuel filter is the same on almost all models of cars, then the place where it is located, they differ. Most often, it is in the engine compartment of the car at the top, it is also often placed in the tank next to the fuel pump. Thus, in modern cars, the fuel filter is either in the engine compartment or in the gas tank or under the car body.

Depending on where the filter element is located, the machine for replacing the machine is either rushed to the lifting device, or put at a convenient position so that access to the part is provided.

The process of replacing the filter of fine cleaning

The conclusion that you need to change the filter can be made from visual inspection. But there are signs for which it can be determined that he clogged: frequent jerks at high and low revs.

If after examining the filter element it turned out that he clogged, that is, two options for solving this problem:

  • try to clean the element from pollution;
  • replace the new product.

You should not wait until the contaminated element manifests itself.

Instruments

A set of tools required for replacement depends on the type of filter element.

The tool kit may include:

  • screwdrivers;
  • a set of keys;
  • pump or compressor;
  • pure rag;
  • gloves;
  • tar for the drain of gasoline residues.

Choosing a new consuming, it is better to buy products with a transparent case.

This will make it possible to track the condition of not only the filter, but also the entire fuel system. If the housing is filled with half a half, then this indicates normal filter operation. If air bubbles are formed in the liquid, it means that there is insufficient density in the fuel and gas station. If the housing is empty, it means that the hose closed, which binds the tank with the atmosphere, or a plug formed in the fuel drive.

For each engine, a certain type of fuel purification filter is required. Therefore, when buying a consumor, it is necessary to carefully read the instruction manual for the car to buy a suitable fuel filter.

Steps

By defining where the fuel filter is located, you can proceed to it.

The procedure consists of the following steps:


When conducting a procedure, security techniques should be followed: smoking is prohibited in the premises. Before the procedure, the room is desirable to air.

Sorry, currently there are no accessible surveys.
