Replacing the fuel filter (injection engine)
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.

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

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 much oil is in the Niva 21214 engine
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.
Manufacturer | Country of Origin | Part number | Approximate cost, rub. |
Romania | ASAM | 30524 | 260 |
Romania | ASAM | 30543 | 275 |
Italy | STARLINE | SF PF7012 | 350 |
Italy | STARLINE | SF PF7043 | 370 |
France | PURFLUX | EP163 | 370 |
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!
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.

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.
Replacement process
Work to replace the filter barrier must be carried out on a lift, pit or overpass.
Tools
- keys at 10,19 and 17;
- rags;
- capacity;
- new o-rings.
Step-by-step instruction
- Remove the negative terminal of the battery.
- Remove the spare tire support bracket.
- Holding the filter with a 19mm wrench, use a 17mm wrench to unscrew the fuel pipe fitting, while slowly removing the fuel into a previously placed container.

Recommendations for choosing and replacing engine oil in the engine of the Niva VAZ 21214 car
Motor lubricant performs the following functions:
Therefore, choosing the right oil is very important.
When choosing engine oil, consider the following. You should look for the API designation on every canister you decide to purchase. It will consist of a rating for gasoline cars (starting with S), and diesel engines (starting with C). These letters are followed by the corresponding letter depending on the age of the oil and the standards to which it meets.
More detailed information about which engine oil to use for the VAZ 21214 engine was found in the manual for the maintenance, operation and repair of the Niva 21213 car and its modifications (Kosarev, Yametov, Volgin, Kozlov). This edition contains the following titles:
And also interesting: Chevrolet Niva air conditioning - installation and repair The leaders among oils for Niva are:
Changing engine oil is an essential component of proper operation of any car. Timely replacement of the working fluid and oil filter allows you to maintain the engine in optimal condition, ensuring its long-term and trouble-free operation. Therefore, the owners of this domestically produced SUV have a logical question about what kind of oil to pour into the Niva 21214 with an injector, how much is required, and how to carry out the replacement procedure yourself.
Selecting oil for Niva 21214 is not so difficult. But here you need to know some nuances in order to avoid common mistakes. Let's start with the time of year. Not every car owner knows what kind of oil to pour into the engine of his Niva if it’s summer or winter outside. In summer the weather is hot, so passenger car engines get very hot under such conditions.
“Niva 21214” is an all-wheel drive SUV, and its engine warms up even more. That’s why many people make the same mistake, filling in mineral or semi-synthetic oil for the summer. To ensure that the engine runs efficiently and does not overheat, experts recommend using high-quality synthetics.
If the lubricating fluid in the power unit has an insignificant percentage of viscosity, you should not expect the expected effect from it. When the cylinder block heats up, such oils have a consistency similar to ordinary water and their temperature rises rapidly. Therefore, the lubricant will no longer take heat from the engine, performing a cooling function, and will also not be able to create the required pressure. Operating in this mode will lead to rapid jamming of the crankshaft.
Therefore, the manufacturer and experienced car owners themselves advise filling the Niva engine, as well as the Chevy Niva (Chevrolet) engines, with motor oils with a viscosity of 20W40, but not higher than 25W50. These are the optimal viscosity parameters at which the crankshaft can function normally and not create unnecessary load.
Avoid semi-synthetic oils. Yes, such mixtures can be expensive and have similar characteristics to synthetics. But even the high price and identical labels on the packaging do not allow semi-synthetics to obtain the same properties that synthetic oils have.
The Niva SUV, in all modifications, is very popular in Russian spaces. This is due to good maintainability, low price and excellent maneuverability. To ensure reliable operation, you should undergo all maintenance on time, in particular, change the engine oil.
The VAZ 21214 engine lubrication system is designed to protect against premature wear of moving parts. It completely copes with its task, you just need to follow all the manufacturer’s recommendations.
The VAZ 21214 engine was conceived as the first injection engine for a domestic SUV. The Niva was not particularly popular in the USSR, but was exported to Asia, the UK, Europe, Latin America and the USA. During production since 1994, there have been several improvements and modifications of the internal combustion engine from Euro-0 to Euro-5 (export).
Transmission
The Niva 4x4 transmission system has the following filling volumes:
As stated in the operating instructions, transmission lubricants need to be changed once every 30 thousand km. mileage At the same time, replacement is not provided for in the steering mechanism housing, only an addition through the top plug. The “native” oil for Zhiguli transmission units is considered to be TAD17I.
Transmission oils have good penetrating ability. Therefore, poorly clamped plugs and worn gaskets of units begin to gradually leak lubricant. In such situations, it is allowed to add oil of the same viscosity class and, preferably, the same manufacturer. If you do not top up during a leak, the lubricant level in the unit will decrease, which will lead to accelerated wear of expensive mechanisms.
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.
The role of the filter in the fuel system of a car
The main task that a fuel filter must cope with is cleaning the fuel coming from the tank into the fuel system of the car. Any fuel, regardless of its brand and cost, contains a lot of impurities, water and dirt. To prevent the latter from getting into the engine cylinder, a fuel purification filter is installed on the way to it.
To achieve maximum efficiency from fuel purification, two types of filters were created - coarse and fine filters. Parts of the first type are designed to capture solid particles with a diameter of up to 0.1 mm. The products have the form of a fine mesh made of brass threads. In the Niva Chevrolet fuel system, the coarse filter is located inside the fuel pump.
Parts of the second type are used to capture impurities whose diameter does not exceed 0.001 mm. They consist of a cylindrical body, inside of which there is a fine mesh. Filters of this type are mounted between the fuel pump and the ramp. If clogged, they must be replaced, while the fuel coarse cleaning elements must be washed without regular replacement.
It is worth noting that in Chevrolet Niva models produced before 2009, the filters were located directly in the engine compartment. The filter in newer cars is located under the bottom.

Where is the filter located?
You need to unscrew the cover to gain access to the barrier
The fuel filter element in a Niva Chevrolet is located at the bottom of the car at the rear, next to the right wheel and is covered with a plastic casing.
Which consumable to choose
You can install an original fine filter. (its GM OEM number is 21231117010). However, many car owners prefer to install imported filters, for example, Bosch 0450905273 or Hummel WK512. Such filters are more expensive than the original ones, but they will also last longer.
Tools
Location
Before proceeding directly to the replacement procedure, you need to find out where the filter element is located. If the car was born before 2009, you need to look for it directly under the hood. If we are talking about more modern models, here it will be located under the bottom.
To get to the filter, you need to remove the rear seats. Under them you will be able to notice the film placed on the sealant. It is enough to carefully tear it off and the device will be right in front of your eyes.
Having figured out where the fuel filter is located on a Chevrolet Niva, it is worth finding out how to replace it correctly.
Signs of a spare part malfunction - study the “symptoms”
Several signs may indicate that it is time to replace the fuel system filter. These include:
The first thing to do if these signs are present is to check the filter. However, even if you do not notice any of the listed “symptoms”, the frequency of filter replacement should be 1 time for every 30 thousand km. This will help extend the life of the engine and other important components of the car.
We recommend: What to do if the handbrake pads are frozen?
It is worth remembering that replacing the filter element is also necessary when performing chip tuning on a Chevrolet Niva, after which the car becomes faster and changes the amount of fuel consumed. In this case, for replacement it is necessary to select a higher quality and more expensive spare part.
Main signs of a clogged or broken fuel barrier
The most common signs:
Sequencing
Replacement frequency
If the gasoline in the tank does not contain foreign impurities, the coarse filter can work for years. It should be checked and cleaned only if the pressure in the fuel line drops. It also makes sense to wash the mesh with carburetor cleaner at every maintenance. The fine filter of the Chevrolet Niva is designed for 30,000 kilometers. However, taking into account the quality of the fuel, it has to be changed after 15,000.
The need for replacement can be determined by the following signs: • Poor traction when driving uphill. • Intermittent operation of the engine, especially at speed and under load. • Increased fuel consumption. • Difficulty starting the engine.
Restyled Nivas are equipped with fine filters GM 21231117010. However, there are many analogues in stores: Bosch 0450905273, Hummel WK512 and others. The price of parts starts from 400 rubles.
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.

Where is it located and how to replace the fuel filter on a Niva Chevrolet
The Chevrolet Niva fuel system requires systematic maintenance. If this is not done, the driver will be in for unpleasant surprises: the engine starts to run jerkily, some noise is heard in it after starting, and fuel consumption increases significantly. These are all signs of a clogged fuel filter that needs to be replaced. We will tell you how to replace it with your own hands in this article.
Before restyling it was located under the hood, after 2009 - next to the rear wheel
The purpose of this element is clear from its name: it must purify the fuel that is supplied to the engine from the tank through the fuel line. Any fuel, even the highest quality, contains foreign particles, water and other substances. All this remains in the fine filter, which on the Chevrolet Niva produced before 2009 was located under the hood, and on new cars that have undergone restyling, this filter is located under the bottom, at the right rear wheel, under a protective cover. This article will discuss replacing the filter on new machines.
The arrow shows a plastic casing on the bottom of the machine, behind which there is a fine fuel filter.
Replacement tools and supplies
Important points
Replacing a fine filter is a task that is entirely within the capabilities of anyone who has at least once held a screwdriver and a socket wrench in their hands. The most important thing is not to forget to relieve the pressure in the fuel system, otherwise troubles cannot be avoided. And of course, we must not forget about safety precautions. All work must be carried out away from sources of fire, and work should only be done with gloves and safety glasses.

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.

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 2 is incorrect. Temporary solution.
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,
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.
The process of removing and replacing the block
So, your heater radiator is leaking, to make sure of this and not engage in “monkey work”, touch the radiator pipes on the front passenger side, if they are dry, then look for a puddle under the driver’s carpet. If the puddle is from antifreeze, it will taste greasy and sweet. So, if all the signs match, then most likely the radiator is leaking.
We go to the store and buy a radiator. I bought a regular aluminum one for 500 rubles and some clamps just in case. You will also need 10 liters of antifreeze. Also stock up on boxes for self-tapping screws, because there will really be a lot of them!
Drain the antifreeze. To get as much as possible, blow into the expansion tank.
I’ll say right away that you need to remove the dashboard if you don’t want to end up at a gas station, although judging by my guesses, even in that case you’ll have to remove the dashboard.
First of all, we remove the glove compartment, it is easy to remove, there should be no problems.
Unscrew the center console along with the radio. There is nothing complicated here either.
Next, unscrew the decorative panel of the center console, which is on the side. We loosen the lining of the checkpoint tunnel. To do this, it is enough to unscrew one (seemingly) extreme screw. On the driver's side closer to the pedals, the passenger moans similarly.
Next, we begin to disassemble the decorative cladding
dashboard, simultaneously throwing off the dashboard and the steering column housing with switches. We take out the air duct, which is located behind the dashboard. Here you will have to suffer with the cables. Why can't you remove the entire dashboard? - you ask. This bolt won't give you anything.
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!
Where is the fuel filter on Niva
The location of the fuel filter on a car depends on the environmental characteristics of its engine:
Regardless of location, the procedure for replacing the fuel filter is carried out according to an identical algorithm of actions.
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 remove and change a fuse
To determine a possible breakdown in the fuse box, you need to use a tester. However, you can also check visually if this item is not at hand. A breakdown is detected if the fuse body is charred.
If it is discovered that the fuse is damaged, its further operation is impossible. In this situation, it is necessary to replace the element with the same, but new one. In this case, it is prohibited to replace it with flag jumpers or wires. If you do this, you can cause much more serious damage to the vehicle.
Fuse boxes always come with spare ones, and experienced drivers often carry these elements with them just in case. In addition, they do not take up much space, and in case of breakdown they can help out the car owner.
As for the replacement process, it is carried out as follows:
At the end of the procedure, screw the cover back and connect the battery terminals. In fact, the replacement process is not complicated, and any driver can handle this task. Therefore, there is no need to visit technical service centers. It is better to learn how to change the fuse yourself and save money than to regularly hand over the car to the hands of service station employees.
As a result, it is worth saying that if a problem occurs when you try to start the engine of the car, the fuse does not play any role. In this case, you should still seek help from professionals at the service station.
