How long does it take to change the fuel filter on a VAZ 21214 injector?

How often to change the fuel filter? – According to the regulations, replacement must be carried out every 30 thousand km. mileage However, if the car is operated in dusty conditions or low-quality fuel is used, then replacement must be done more often.

Where is the fuel filter located? – If the filter meets Euro-2 toxicity standards, then it is installed in the engine compartment on the left front mudguard under the spare wheel.

– If the filter meets Euro-3 toxicity standards, then it is installed under the bottom of the car, in a recess, above the additional muffler.

We carry out the work on a cold engine.

You mean that the fuel in the power system (with the ignition on, as well as for some time after) is under pressure. Therefore, before replacing the fuel filter, the pressure must be relieved. If the car’s ignition has not been turned on for more than 3 hours, then there is usually no pressure in the fuel system. You can check the pressure by unscrewing the cap of the fuel rail fitting and pressing the spool rod. (see here)

You also need to keep in mind that the filter is located below the level of the fuel tank and when it is removed, fuel can flow out of the tank through a tube disconnected from the filter. Therefore, you need to have a container to collect fuel.

To relieve pressure in the system, remove the lining of the left front sidewall (see here).

We disconnect the connectors connecting the wiring harness of the engine management system and the rear wiring harness.

We start the engine and let it idle until the fuel runs out. Then turn on the starter for 2-3 seconds. After this, the pressure in the power system will be released.

Disconnect the negative cable from the battery.

To remove the filter under the bottom (Euro-3)

To remove the filter under the hood (Euro-2)

Remove the spare wheel support bracket.

Holding the filter with a 19mm wrench, use a 17mm wrench to unscrew the fuel pipe fitting, gradually bleeding the gasoline into the substituted container.

Niva fuel filter

The filter is an important component of the fuel system of a vehicle - the life and service life of the power unit and adjacent vehicle systems directly depends on the quality of purification of the incoming fuel.
That is why it is necessary to change the fuel filter in a timely manner, adhering to the conditions of scheduled maintenance and the car manufacturer’s regulations.

As is correct, when replacing an old filter, drivers choose foreign-made options - the original filter on the Niva has a short lifespan and quickly becomes clogged.

The most popular fuel filter models for Niva are presented in the table below. All parts comply with the stated standards of the official manufacturer.

According to the automaker's regulations, the fuel filter on the Niva must be changed every 30,000 km. However, the need to replace the part may arise much earlier - if low-quality fuel is poured into the car or the car is driven on dusty or dirt roads, then the filter needs to be changed every 15,000 km.

Remember, the service life of the engine depends on the timely replacement of this element; a clogged filter significantly speeds up the production of engine components.

Note! It is strictly not recommended to install a fine filter on a car, especially when refueling the vehicle with low-octane fuel. The fine filter does not provide adequate filtration quality, as a result of which small abrasive elements and chips can get into the internal combustion chambers of the engine, which will reduce the service life of the engine. This type of tuning is not compatible with the domestic auto industry!

How to replace a fuel filter with your own hands: step-by-step instructions

The algorithm for replacing the fuel filter on a Niva is carried out according to an intuitive scenario - all consumable components in the domestic automotive industry can be easily replaced with your own hands without outside help. To service the fuel system, you will need a set of wrenches, a rag for wiping, and a canister for draining remaining fuel. To replace the fuel filter you must:

It must be remembered that replacing the fuel filter should only be done when the engine is not warmed up.

After replacing the fuel filter, it is imperative to check the tightness of the system when starting the power unit - with the engine running, there should be no air leaks through the main pipes or the contact points of the filter with the hoses.

How to replace the fuel filter on a Niva Chevrolet?

To extend the life of your car, filter elements must be changed at least every 30,000 kilometers. In our conditions, which Europeans consider extreme (dirt dusty roads, low quality gasoline, gas pollution in megacities), it is better to halve this period. Replacing a Chevrolet Niva fuel filter is one of the most important aspects of car service, because the condition of the car’s power unit largely depends on it.

Attention! When working with the fuel system of your car, do not smoke under any circumstances, and replacing the filter element should be carried out as far as possible from gas stoves, stoves and other appliances.

Filter

Attention! The engine system is under high pressure; therefore, after stopping it, loosening the fuel drives is strictly prohibited. After turning off the engine, you must first reduce the pressure before starting work on the power system. It takes about three hours for the pressure to drop to zero.

How to reduce pressure in the engine power supply system?

Method No. 1

Unscrew the nut securing the cover of the engine control unit - it is located inside the passenger compartment.
Remove the cover.
Remove the fuse for the electric gasoline pump.
Turn on the engine, it should run until all the fuel in the fuel line is exhausted. When this happens, the engine will stall on its own.
Reinstall the fuse.

Method number 2

You can reduce the pressure using the control valve, which is located behind the fuel rail; it is closed with a cap (usually made of plastic). The design of the valve is similar to a wheel spool.

Unscrew the cap and drain excess fuel by simply pressing the valve.

Disconnection of the fuel wires is possible only after this procedure. Be extremely careful! Gasoline will come out under pressure.

Main signs of a clogged or broken fuel barrier

The most common signs:

When the engine warms up, extraneous noises are heard. They may appear periodically.
When driving uphill, the engine becomes difficult to operate.
The power unit operates jerkily.
Increased fuel consumption.
The engine does not start.

Replacing the Chevrolet Niva fuel filter: step-by-step instructions with photos

In order for the car’s power unit to operate efficiently, it is necessary that only purified fuel enters it. For this purpose, the corresponding filter element must be replaced regularly. Today, a car such as the Chevrolet Niva is very popular. Owners of such a vehicle should read this article, because it will talk about how to replace the fuel filter on a Chevrolet Niva, as well as some other important details.

We replace the Niva Chevrolet fuel filter with a new one.

To set a Chevrolet Niva SUV in motion, it is necessary that high-quality fuel enters the engine. But before it gets into the gas tank of a car, the fuel travels a long way from oil refineries to gas stations, moving in fuel tankers and pipelines along the way. Then it is stored in an underground container, waiting in the wings. On this path there is a high risk of various small debris, water and other particles getting into it. Over time, condensation may also form in the gas tank. If all this gets into a running engine, then there is a high probability of increased wear of parts and mechanisms. Therefore, such a necessary part as the Niva Chevrolet fuel filter is installed so that the quality of the mixture can be adjusted.

Replacing the fuel filter on a Chevrolet Niva is a fairly simple procedure that can be done independently. Let us consider in more detail the purpose of this part and the main prerequisites for its replacement.

Filter location

This element is built into the fuel line between the tank and the injectors. It is necessary to prevent particles of debris, dust, rust, etc. from entering the combustion chamber.

To ensure maximum cleaning, there was no need to frequently replace components in cars with a two-factor system consisting of a coarse and fine filter.

Coarse cleaning - needed to retain particles with a size of 0.1 mm. It is a fine-grained mesh, which is made mainly of brass. The device is located near the gas tank. In the Chevrolet Niva it is built into the fuel pump. This product can be cleaned by washing, so there is no need for frequent replacement.
Fine cleaning – designed to remove dust and impurities up to 0.001 millimeters in size. This is a cylindrical device, inside of which material with small fractions is placed. Installed between the pump and the fuel rail. It usually fails more often, but replacement is quite simple.

What kind of carburetor is originally installed on the Niva?

The Niva car is equipped with carburetors from the classic “Ozone”, which is not the best two-chamber unit with an idle economizer. The economizer is an autonomous system with a solenoid valve that automatically comes into operation when the ignition is turned on. When the speed increases above 1000, it is turned off, and the engine is maintained using an air damper.

The updated model received the French Solex design. The 1.7-liter engine required an increase in the amount of air-fuel mixture, and therefore Ozone was no longer used.

What increases gasoline consumption on Niva series cars

Fuel consumption for the Niva 2131 is 16.5 liters in urban conditions, 12.1 liters for the mixed version and 9.7 liters for the highway. This figure can hardly be significantly reduced, and it easily increases due to improper operation of any vehicle, including:

Fuel consumption can be increased if the engine, for example, on 21214, operates outside the operating temperature. This could be a problem with the cooling system, including the thermostat, fan, cooling sensors, or coolant. It will be relatively cheap for “nivovods” to replace the thermostat, which costs about 350 rubles. The operation is performed independently, since all you need is a Phillips screwdriver.

To replace the part, you need to drain the antifreeze, then unscrew all the bolts on the pipes from the thermostat clamps, remove the pipes and remove the element from under the hood. Using a ratchet handle and a socket on “13”, you can easily change the VAZ 2121 radiator fan by unscrewing just three mounting bolts. Thus, it is possible to adjust the ventilation system without extra costs so that operating temperatures in the engine do not exceed the required 98-102 degrees Celsius.

Work and consumables can be much more expensive if the problem of increased fuel consumption is associated with poor operation of the SBU, which is based on incorrect sensor readings. In this case, problems may arise with the lambda probe, mass air flow sensor, throttle position sensors, and temperature sensors. In this case, it is better to go to the stand at the service station.

Fine fuel filter

Post by elwolk » Aug 27, 2012, 10:15 pm

The fuel filter often gets clogged; gasoline in the region is excellent. (niva injection) I opened a couple of filters of different brands with a hacksaw, inside there is a completely different device. In one there was a piece of paper stupidly across, and with a little effort it stood along the O_o filter, so it became end-to-end. The filter of another brand had a completely different device, which was incomprehensibly metal.

What filters should you give preference to, what do you think?

Re: Fine fuel filter

Post by doc Brown » Jan 28, 2013 10:24 pm

Not such a good thing, as it turned out. I had it in front of the gas pump for about a year; the actual mileage on gasoline during this time was five thousand.

In winter. In addition to warming up before switching to propane, I had to travel on more gasoline, because in Murmansk there was no gas at gas stations for a month and a half. Therefore, I took a closer look at the gasoline power system. During the New Year holidays, I set out to finish up the secondary chamber of my carburetor. It overfills it with gasoline when opening it, and therefore, instead of the expected acceleration, a “dulling” is observed. But now we are not talking about the selection of jets. When opening the carburetor, rust was found in the float chamber, which made me very upset.

The filter was temporarily replaced with a regular plastic sump and mercilessly sawed apart.

A similar filter, which had been standing for two years on a heavily used Opel Vectra, was also sawn apart. It turned out to be clean inside. This hardly says anything about its filtering abilities. Rather, it’s about the fact that the tanks on Opels don’t rust (the car is from 1992).

After driving for a week with a plastic filter, I again found traces of rust in the float chamber. But this filter was not expected to be particularly impenetrable. Based on the experience of my old cars, the best way to combat rust is by weight, not size. Therefore, after the fuel pump, I installed a fine filter from an old Volga, with a deeper sump.

The experiment is not over yet. The process of selecting jets continues, so I’ll look into the carburetor again. If necessary, I will install a ZiLovsky coarse settling filter. Its effectiveness in fighting off rust is very difficult to overestimate.

Option 1 is correct. 1. Drain the fuel from the tank 2. Remove the tank After this: 1. Visually check the tank for rust. if there is, clean it. You may have to fill the tank with water and boil the holes. DO NOT COOK EMPTY UNDER ANY CASE! 2. Unscrew the fuel intake, shine an LED flashlight inside, and be horrified by the layer of dirt. 3. Wash everything thoroughly, “unscrew” the tank, or use a drain plug (I don’t recommend it - then you won’t screw it tightly for anything. The tank is old - it’s ruined by metal). 4. Place the heel on the fuel intake (coarse filter - does not allow water and dirt to pass through). Buy a normal one, check it directly on the market. 5. Completely replace the fuel line. Place the filter vertically - supply from below, intake from above. (the arrow should point up) 6. Install a new normal coarse filter. (and change it every 5,000 - 7,000 thousand) 7. Install a new normal air filter - for example, a zero filter (but you will have to take a corrugation, a turtle for it and sculpt a pan yourself - without it it’s not comme il faut.) and impregnation for it. Service it once a week. 8. Completely disassemble and wash the carburetor with carbcleaner, replace the coarse filter in the carburetor intake, check the jets and float. The fuel system is ready for operation.

Option 2 is incorrect. Temporary solution.

1. Place the heel on the fuel intake of the gas tank (coarse filter - does not allow water and dirt to pass through). Buy a normal one, check it directly on the market. 2. Unscrew the line from the tank, the other end from the filter in the engine compartment, point it in the direction “somewhere so that it doesn’t get on anyone,” ask a friend to hold it. 3. Take the compressor and blow out the line (a fair amount of Mr. will fly out of it), first at a pressure of 4 atm, then at 8 atm. 4. Install a new normal coarse filter. (and change it every 3000 - 5000 thousand) 5. Completely disassemble and wash the carburetor with carbcleaner, replace the coarse filter in the carburetor intake, check the jets and float. You can somehow drive.

From your photos - in the third photo you can see how much Mr. has settled on the filter (I can imagine how much there is in the line and in the tank). So, what went into the carb is what the filter couldn’t cope with, because... was already clogged and had lost its permissible capacity. Otherwise it would be in the carb, as it will be now when you installed a plastic filter. I went through this and I don’t recommend it to you. Better

and do option 1. Sincerely,

How to replace a fuel filter with your own hands: step-by-step instructions

First of all, turn off the power supply to the vehicle - to do this, you need to remove the negative terminal from the battery;
Then you need to remove the bracket that secures the spare tire support to the car;
Next, use wrenches to unscrew the fuel pipe fitting. Please note that when dismantling the pipe, the gasoline that is in the fuel line will begin to drain - you need to put a bottle or canister for draining;
After dismantling the first pipe from the filter, we also remove the second element. It must be remembered that at the ends of each pipe there is a rubber sealing ring, which must be replaced after replacing the filter - otherwise gasoline will leak;
Now, using a “10” key, unscrew the fixing clamp that holds the filter itself, after which the part can be replaced with a new one.
The procedure for installing a new filter and assembling the system is carried out according to these instructions in strictly reverse order. When installing the filter, you need to check the polarity of the part - the element must be installed with the arrow pointing towards the rear of the car. Otherwise, the filter will not work correctly and the maintenance procedure will have to be repeated.

It must be remembered that replacing the fuel filter should only be done when the engine is not warmed up.
