How to change the fuel filter with your own hands on the VW Polo sedan. How to change the fuel filter on Volkswagen Polo sedan polo sedan gasoline filter generic how many barrels

Volkswagen Polo, like all modern cars With a distributed fuel injection (injector), it is particularly sensitive to the quality of gasoline and the presence of water and impurities in it. To protect the engine nozzles from extraneous particles and ensure them stable work Filter is installed in the fuel supply system thin cleaning. Over time, dust, dirt and rust accumulate in the pores of the filter element and reduce the efficiency of its operation, so the fuel filter is subject to periodic replacement.

Official Regulations maintenance VW Polo with a 1.6 engine provides for the replacement of the fuel filter after 60,000 kilometers of the path traveled or every 2 years of operation (depending on which event comes before). However, the well-known situation with the quality and pollution of domestic fuel introduces some adjustments: if the owner plans to ride on his Volkswagen for a long time, the regulatory time is worth cutting up to 10 thousand km of run or at least once a year. Many car owners combine the installation of a new gasoline filter with another substitute for engine oil.

Signs of fuel filter clogging

There are several signs that show that the operational replacement of the filter element is required, regardless of the magnitude of the mileage and the interrontal interval:

• unstable operation of the motor (engine troit or periodically stalls, float at idle speed);
• reducing the traction characteristics of the car (the sluggish set of speeds, difficulties in motion on the rises);
• increased gasoline consumption (compared to the usual indicators of a particular car).

Such malfunctions can suddenly occur after visiting a dubious filling station or due to the inaccurability of car service specialists, if the dirt particles hit the fuel system during the repair system. Also, premature replacement may be required when using cheap filters from unverified manufacturers.

Fuel filter device

A structurally fuel filter is an unintended steel cylindrical body, inside which the filter element and pressure reset valve are placed. Since the filter is located on the bottom of the car, its housing is covered with a special anti-corrosion coating. In the ends of the housing there are fittings for the attachment of benz pipelines. A special paper is usually used as a filter material that captures extraneous particles with a size of 10 microns.

The fuel from the gas tank is poured into the filter through the side fitting, flows through the filter surface and is supplied through the fuel line to the engine injector. With overpressure in the system, the valve is triggered, and gasoline is merged back into the fuel tank.

A wide selection is available on sale. fuel filters For Volkswagen Polo from various manufacturers:

Fuel purification filter replacement procedure

The filter is fixed on the bottom of Volkswagen Polo around fuel tankSo the replacement work is recommended on the overpack, the lift or, putting the machine to the observation pit, which will facilitate access to the served node.

Before the start of work, it is required to reset the pressure in the fuel system of the car. To do this, you need to remove from mounting block Fuse fuel pump (polo sedan is a 15 A fuse №36, and then start the engine. When the motor stalls, you can turn off the ignition and start replacing the part.

Before depressurization fuel system It is recommended to clean the filter housing and the joined benz pipes from dust and dirt, if necessary, you can wash the elements with water and wipe dry.

To disconnect the fuel hoses, you need to gently press the locks of the latch with a flat screwdriver and move the benzins from the filter fittings. After that, you need to unscrew the screw on the cottage, which holds the filter on the car case.

The new filter element is installed in the reverse sequence, the fuel lines are connected, the fuse of the gas station is installed in the mounting unit.

Before starting the engine, it is necessary 2 - 3 times turn the key to the first position and wait for the operation of the fuel pump - this will avoid bringing the gasoline feed system. After that, the car can be started. After completion of the work, it is strongly recommended to check the fuel filter compounds with fuel pipelines to make sure the system tightness.

Fuel filter It is a mechanism that prevents the ingress of different elements of foreign origin into the fuel and motor system. The need for this device is doubly relevant due to poor-quality fuels in Russia. For undime replacement The fuel filter, the fuel line would fall into the fuel with impurities, which would certainly lead the motor system to a very emergency breakdown.

When to change

As already mentioned, the fuel filter is a regular consumator that needs to be changed every 20-25 thousand km. Or a year and a half exploitation, as the factory VW plant recommends. However, it is necessary to take into account poorly fuel and foreign impurities, and the filter is doubly flashed faster. When operating a car on the territory of Rossi, it is recommended to change the filter every 10-15 thousand km.

The first sign of the worn fuel filter is the hard start of the engine. In addition, a noticeable increase in fuel consumption and a reduction in the car's capacity is also inherent in a worn fuel filter.

Instructions for replacing the fuel filter on VW Polo do it yourself

The fuel filter replacement procedure requires no more than 1 hour. The fuel filter is and is attached to the right of the gas tank car. When replacing the filter, either lifting boxing is needed or an observation pit, you also need to have a minimum of tools, such as:

1. Screwdriver cross.
2. Rag.
3. Fuel filter.
4. Looking pit or boxing.

Replacement procedure:

1. Install the car on the observation pit.
2. Disassemble three fuel filter fittings.
3. Remove hoses. You can remove them by clicking on the button on the fastening of the hose. Press and push off. It is worth being caution, because gasoline is located in the entire fuel line and the leakage is inevitable.
4. Unscrew the fastening bolt of the fuel filter with a cross screwdriver.
5. Remove the filter.
6. Remove the plugs from the new fuel filter and set it to the place of the old one. On the new filter there will be a special arrow, which shows the direction of gasoline flow from the tank to the engine. In the installation is not mistaken.
7. Dress down hoses before clicking.
8. Split screws.
9. Check the filter on the leaks from the hoses. To do this, run the engine and climb under the car. If there are no outers - drown out the car.

As you can see, there is no need to attend the service center to replace the fuel filter. This can be done by himself, even without having experience in repairing cars.

On Volkswagen Polo.

As it is clear, the operation of the fuel system determines the efficiency of the operation of the motor, also the dynamic and high-speed parameters of the machine as a whole. And the gradual decrease in the fundamental technical features of the car has an impact not only only on the quality of driving, and for the appearance of a breakdown. In this article, we will tell you how often the fuel filter is being made to the Volkswagen Polo car and how it is done.

The German manufacturer does not give accurate instructions on the substitution interval fuel filter. Manufacturers from the Volkswagen concern assure that the filter for the car's fuel polo sedan can be reliable to work as much as the car itself. The original fuel fuel fuel filter on the sedan polo. When you change the candles and. In particular, Volkswagen argues that the life of this component is equal to the deadlines for the use of the entire car. However, domestic drivers have proven that in practice everything is different. The performance of this part, primarily affects the quality of gasoline refueling and various dirt falling into the fuel system through it despite all precautions taken by the concern engineers.

As practice shows, it is best to replace the gasoline filter every 20-30 thousand km of mileage. In Russian Skoda Rapid and Volkswagen Polo Fuel filter change it on. Remember, such numbers are not provided by the manufacturer, but by domestic motorists, so replacing the fuel purification element can be carried out earlier in case of clogging. If, during the movement, the engine starts to trim or periodically stuff, then in all likelihood, the use of the filter in your car came to an end.

New Filter KL 756 for VW Polo Sedan.

In the early stages of clogging, the fault component can be invisible for an inexperienced driver, but the experienced motorist will be able to detect a breakdown on time. As for signs of breakdowns of the element in the Volkswagen car, they are the following:

1. As mentioned above, first of all - this is uneven operation of the motor.
2. Also owners of polo sedan models note the drop "traction" (power) car.
3. Another feature is an enlarged gasoline consumption as a result of the component clogging, if compared with standard indicators specifically for your machine model.
4. If you can't get started, and before this your car Troilo and "Chish", then, in all likelihood, fuel The filter has reached the extreme level of pollution.

VW Polo Sedan (2010+). Major faults because of which fuel enters the engine oil

Most breakdowns can be divided into two large groups, properties and characteristics of which differ from the type of engine used.

Gasoline hit the engine oil

The fuel is capable of being in oil, and even in engines with a fully operational cylindaneous group.

The specified problem is quite serious and can lead to malfunctions, a significant reduction in the motor resource, as well as to the complete failure of the power plant.
Gasoline in oil significantly worsens the protective properties of the lubricant, dilutes the lubricant. If you do not go into details, the more gasoline falls into the crankcase, the more seriously there may be consequences.

With a minor quantity of fuel in lubricant, the motor can work more noisy, while the wear of loaded nodes will increase slightly. To solve the problem, it will be sufficient to eliminate the problem of gasoline flow into the crankcase and replace the engine oil.
In other cases, riding on a very diluted fuel oil can cause the engine at which expensive overhaul becomes necessary.
The list of basic signs that in one degree or another may indicate the emergence of the problem under consideration, the following are noted:

The power unit loses its capacity, there is a noticeable overrun of fuel;
The exhaust becomes thick, grayish, has the smell of unburned gasoline;
There are failures in dVS work, the engine begins to trim, stuck;
Motor began to work noisily, there were knocks in the field of pistons, crankshaft, etc.
The lubrication level in the crankcase is increased, while the smell of gasoline in the engine oil is clearly heard;
Lubricant is thinned, a drop of engine oil easily lights up from open fire;
If you suspect a minor amount of gasoline in lubrication, you can also additionally estimate the properties of the oil using the "oil spots" method. To do this, it is enough to drop one drop of oil with a probe on a sheet of pure paper. Then you need to dry the leaf a couple of hours. Smooth smooth edges of a growing drop will indicate that the material has not lost its properties.
The black contour in the center of the spot indicates the presence of workable additives in the lubricant. We also note that this method It is also useful for the general quality audit, the state of the oil, the identification of the presence of water and other impurities in it.

If any of the indicated signs were noticed (noise during operation, knocks, overrun, lubrication, smell of fuel, a drop when calibrating on a sheet differs from normal), then it should be prepared for the fact that gasoline can be in the oil.

As already mentioned, the consequences of further riding on such a mixture can be different. The main thing, gasoline is a rather aggressive product with respect to lubricant materials, as it contains a large number of chemical additives.

In engine oil, also contains a whole package of additives, while the specified additives are not designed for direct contact with the fuel. In other words, there is an irreversible change in the physical and chemical properties of engine oil. For this reason, raising the oil level due to gasoline is a serious threat to the engine.

I also add that antifreeze can also fall into the oil system, as a result of which the emulsion is formed. In this case lubricant Also loses its properties. If the leaks are intense, then at the time of starting the motor can occur.
As for gasoline in lubricant, a certain danger is that quite often fuel dilutes the lubricant gradually, that is, it falls in small quantities. This means that the driver does not notice the problem for a long time, continuing to exploit the unit in the usual mode. In this case, the wear of the motor increases greatly. Now let's move on to how gasoline gets into the oil.

How gasoline enters the oil: troubleshooting

To understand why gasoline in engine oil, you need to contact constructive features Differs.

First of all, on any motors (injector, carburetor), fuel falls into the Carter from the combustion chamber through the piston rings. It is important to understand that if pouring gasoline into the cylinders of the new motor, after a while it will be in oil. The reason is simple - fuel flushes the oil film and passes through looseness in the location of the piston rings.
For motors with a carburetor frequent cause of gasoline entering the oil is damage to the fuel pump diaphragm. Another reason for diluting the oil fuel is the problems with a needle valve of the carburetor in the float chamber, overflow fuel into the carburetor, etc.
Taking into account the above, it becomes clear that the main cause of gasoline in the lubricant is problems with the system or ignition system, as well as with the OI itself. It turns out that malfunctions may arise due to the fact that:

There is a significant re-enricmentation of the working mixture;
There were malfunctions of fuel injectors, carburetor, mechanical benzonasos;
The ignition system is defective or works incorrectly;
The engine is faulty or worn, no desired compression in the cylinders, the fuel is not ignited;
In other words, fuel can be supplied in excess, but the rich mixture is not ignited. Also, gasoline does not burn, since there is no spark on the spark plug or the charge does not burn due to low compression in the DVS. In any case, unburned fuel falls into Carter.

If the carburetor "overflows" the gasoline into the float chamber or "pour" injection injectors, then fuel will also block the cylinders and then fall into the oil. In order to exclude fuel from entering the oil in one way or another on the injector, it is necessary to check the tightness of the injection injectors and make them clean.
It is also recommended to conduct computer diagnostic Motor, evaluating the quality of the mixing formation, separately "nicknit" the ECM sensors that can affect the formation of the mixture. The condition of the fuel pump diaphragms is controlled on the carburetor internal engine, is regularly configured and the carburetor is diagnosed.

Before cold start (especially in winter), it is necessary to periodically monitor so that flowing gasoline does not appear under the carburetor. If such a phenomenon was noticed, then check the carburetor.

In parallel, you need to pay attention to the special drainage tube. If the tube is clogged, the surplus of fuel when problems with a needle valve begin to fall into the CARTER DVS. Now let's take a look at the most common causes in more detail.

Considering the fact that the fuel feed system on different engines It can be very different, differ and ways of gasoline entering the lubrication system. In motors with injector, gasoline is supplied from the fuel tank under pressure, which creates an electric fuel pump. At this stage, the oil with flammable can not be mixed.

At the same time, mechanical benzonasos is installed on carburetor motors. The diaphragm of such a pump is injected by gasoline into the carburetor installed on the engine. The rod of the mechanical pump on some auto has a drive from the eccentric, and also lubricated with engine oil by the same scheme as the camshaft.
If the pump diaphragm is damaged, gasoline begins to enter the rod channel, penetrating the lubrication system. When the membrane is not damaged, then the accumulation of gasoline in oil will occur slowly, the lubrication level will not rise. The problem seems to change the smell of oil, as well as some disclosure.
In the event that the membrane has large gaps, gasoline ceases to be supplied to the carburetor, the engine is launched with difficulty, jerks and failures appear when moving, the unit works unstable, etc. To eliminate malfunction, it is necessary to replace the gas station membrane, as well as engine oil.

In the injector, most problems are associated with nozzles, since the ignition failures, the experienced driver fixes immediately. A more complex is the situation in which one or more injectors cannot be closed hermetically. This means that after stopping the motor fuel, which is located in the fuel ramp under residual pressure, proceeds to the collector, then falls into the cylinders, then flows into the crankcase.
Piston rings To some extent prevent gasoline falling into the oil, but if they are worn or fondered, then fuel relatively freely falls into the pallet with oil. To solve the problem, you need to remove the fuel rail, after which the tightness of each injection injector is checked.

To do this, flushing fluid or kerosene is supplied to the injector under pressure, as well as the opening and closing of the nozzle from the power supply. You can use a special bench for checking and cleaning nozzles. If the nozzles flow, then they need to be repaired or replaced.

As for the ignition system, if in one of the cylinders or in several mixtures is not ignited, then part of the fuel fly out in graduation systemAnd the remaining parts simply settled on the walls of the cylinders, then flow into the Carter DVS.
Faults of the ignition system are diagnosed in normal order. First, the spark plugs are checked, then high-voltage armorberry, coil, rubber, and other elements that are installed on a particular car.
CPG wear is the general problem of carburetor and injection engine. As a rule, we are talking about the wear of compression and oiling rings. In such a situation, fuel actively flows into the Carter. It is important to take into account that problems with rings also lead to a decrease in compression.
It turns out, the mixture is worse compressed and burns deficiently, the engine loses power. The driver is stronger than gas, feeding more fuel into the combustion chamber, but the burning does not fully occur. Excessive fuel leads to the contamination of the motor and the formation of a car, and also partially falls into the crankcase.

Causes of leakage

Fuel, regardless of the type of power supply system, after a gasoline pump should reach a carburetor and combustion chamber. The latter presents the part of the GBC (the head of the cylinder block) and the piston head, where the combustion of fuel and oxygen is combustion. A mixture of fuel and air on the way to the combustion chamber passes the channels inlet, their necks are always lubricated by car. Here there are leaks. The reason lies in the fact that the valves are equipped with rubber caps. They are designed to reflect the car. If, due to the strong wear of the caps, the lubricant will penetrate into the combustion chamber, the exhaust cars will become smoke from motorcycles. The chance that the car will fall into the combustion chamber, rather low. Usually oil smells with gasoline for other reasons. If you start the car in winter conditions, gasoline 1st a couple of minutes will burn inefficiently. Traffic fumes It smells raw fuel, condensate flows from the exhaust pipe. This is completely normal.

Eventually

If gasoline enters the oil, then the engine before eliminating the breakage should not be operated. This phenomenon is especially dangerous when the driver did not know about the problem, that is, a large amount of gasoline has accumulated in the crankcase, the pressure in the lubrication system fell, on dashboard An emergency oil pressure light light up.

In such a situation, it is necessary to immediately eliminate the main problem by repairing the ignition system, carburetor or injection injection. Also, an obligatory procedure will be the replacement of oil with which it is better not to delay.
Finally, add that in some cases the reason for the inefficient combustion of the mixture in the cylinders may refuse the fuel itself. The fact is that gasoline is often very low quality.

Fuel, which is mixed with third-party additives, is worse. Unburned residues can also fall into the car carriage. In some cases, it is enough to replace the oil and start refilling on another gas station.

Also in some sources for prevention purposes, it is recommended to twist the motor to high revolutions during a short period of time, making trips along the highway. Such ride leads to a higher heating of the oil, which helps reduce the content of the accumulated condensate and falling into fuel lubrication.

When to change the fuel filter polo sedan

According to the service book, the fuel filter replacement is carried out every 60000 km. However, the application is not enough quality gasoline and low-quality additives, refilling with eaten gasoline, the application affects the mileage of the replacement of TF.

In severe operating conditions, the fuel filter replacement is recommended to produce after 30000 km.

In addition to the regulatory, it is possible to replace the fuel filter when the fuel pump hum is appeared. This is an explicit signal that reports the occurrence of breakage in the system.

If you have no repair skills to perform this procedure and you are not sure about your abilities, then better contact the maintenance station.

Tools and materials to replace the fuel filter

For successful I. fast replacement TP VW Polo needs to be purchased in advance required tools and materials.

What fuel filter polo sedan put - the original fuel filter with the VAG 6Q0201051 pressure pressure regulator is recommended at a price of 1140 rubles. Analogs are allowed such as: MANN-Filter WK692, UFI 3183300, Big Filter GB3229, Filtron PP8364, Bosch F026403006.

The price of suitable filter analogs will be 300-500 rubles below, depending on the manufacturer's company.

Since the fuel filter is located under the car, then for the successful completion of work, this procedure is recommended to implement observation pit, Overpass or lift.

From tool need:

• cross-shaped screwdriver;
• clean rags;
• tara for gasoline drain from the filter.
