How to change the fuel filter on a Chevrolet Niva yourself

Attention! If the car is operated in dusty conditions or with low fuel quality, the filter must be replaced more often than specified in the regulations.

The fuel filter is installed at the bottom of the car, in front of the right rear wheel and is covered with a plastic casing.

We carry out the work on an inspection ditch or overpass.

The fuel in the power system (with the ignition on and for some time after it is turned off) is under pressure. Therefore, if we replace the filter immediately after a trip or after turning on the ignition, it is necessary to relieve the fuel pressure in the power system. If the ignition has not been turned on for a day or more, there is usually no fuel pressure in the system.

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

Where is it located and how to replace the fuel filter on a Niva Chevrolet

Chevrolet Niva is a fairly well-known brand, and most service stations know what is included in the service of this model. But experienced car enthusiasts can do some operations themselves - for example, replacing the fuel filter.

The fuel filter in the Chevrolet Niva is located under the car, in front of the right rear wheel, so replacement will require an inspection hole or overpass. For cars produced earlier than 2009, this is not necessary - the filter is located under the hood, on the right passenger side.

When replacement is necessary

In Niva Chevrolet, the fuel filter is recommended to be replaced every 30,000 km. If the gasoline is of low quality or you have to drive off-road, then you need to do this more often. We present the obvious signs of the need for replacement in the form of a list.

Signs of a clogged or broken filter

• when the engine is running, extraneous noise periodically appears;
• fuel consumption increases;
• the power unit began to operate jerkily;
• the motor does not start.

Catalog number

The Chevrolet Niva is a well-known car in Russia, so if you ask for a fuel filter specifically for this model, the Gazelle will mistakenly not give you one. But, like any other factory part, it has a catalog number - “2123–1117010” or “21230–1117010”.

To work we will need the following tools:

• crosshead screwdriver;
• key to 10;
• rags for wiping;
• capacity, since fuel will remain in the filter;
• new o-rings.

And of course, the filter itself.

While the engine is running, the fuel is under high pressure, so removing the filter immediately after a trip is highly recommended. If possible, leave the car for a day so that the pressure drops naturally.

How to relieve pressure

If time is running out, use the following method.

Disconnect the wires Remove the cover Unscrew the screws Raise the right rear seat cushion

1. Raise the right rear seat cushion to a vertical position and bend the sound insulation;
2. Using a Phillips screwdriver, unscrew the screws securing the cover (2 pcs.);
3. We remove it;
4. Disconnect the wiring block from the module, first releasing the latches;
5. We start the engine;
6. After it stalls (a couple of seconds after the start), turn on the starter for two to three seconds.

The pressure has been released, you can move under the car to replace it.

Remove the filter Loosen the retaining clamp Remove the protective cover Unscrew the protective cover

1. Unscrew the fastenings of the protective casing (bolt and two nuts).
2. Let's take it off.
3. We loosen the clamp that holds the filter in place (there is no need to unscrew the connection completely, just loosen it).
4. Having squeezed the tube clamps, we disconnect them from the old filter, draining the fuel into a previously placed container.
5. Remove the filter.
6. The new one is installed in the reverse order, but do not close the casing cover yet. We place the part so that the arrow indicates the direction of fuel movement (looks at the engine).

7. Then we return the wires to their place (in the cabin under the seat).
8. We start the engine (since we changed the filter, the engine may not start on the first try - this is normal) and visually check the connections for leaks.
9. If there are no leaks, install the casing cover in place.

Having the necessary tools at hand, you can replace the fuel filter in a Chevrolet Niva in thirty minutes, and even a novice driver can handle this job.

Since fuel remains in the filter, we drain it into a previously prepared container.

We install the new filter in the reverse order.

Regulations

In accordance with operating instructions, the Chevrolet Niva fuel filter must be replaced every 30,000 km. But when driving in unfavorable and difficult conditions, which include low fuel quality, dust, etc., it is recommended to shorten the interval.

Tools

To complete the work you will need the following tools:

1. Phillips screwdriver;
2. Collar;
3. Extension;
4. Head 10;
5. Container for draining fuel.

Job

The fuel filter itself is located at the bottom of the car, in front of the rear right wheel, and is additionally covered with a plastic casing.

Before you change the fuel filter on a Chevrolet Niva yourself, you need to drive the car onto an overpass or pit.

IMPORTANT! Provided that the ignition is turned on, as well as for a certain time after it is turned off, the fuel in the system is still under pressure.

This means that if the replacement is carried out immediately after driving or after the ignition key is removed, it is necessary to relieve pressure in the system.

To relieve pressure, you need to lift the rear seat cushion. This will provide access to the hatch cover, which is screwed on with 2 self-tapping screws. You need to unscrew them and then remove the cover.

Then disconnect the wire plug from the fuel module, first releasing the lock on the plug.

Next, to replace the fuel filter on a Chevrolet Niva, you need to start the engine and leave it running at idle so that it produces gasoline (this lasts a few seconds). Then turn on the starter for 2 or 3 seconds.

This completes the pressure release procedure. But it’s better to leave the car for about a day and only then start working.

The next step is to remove the fuel filter housing. It is secured with a bolt and 2 nuts, which require a 10 mm socket to unscrew.

Then the tip is removed from the filter fitting, for which the 2 clamps of the tip of the fuel outlet tube are compressed.

Then, using a 10mm socket, you need to loosen the filter clamp bolt.

Then move the filter, removing the fitting from the tip of the tube and first squeezing the 2 tip clamps. This will allow you to remove the filter itself from the clamp.

Note. There will be gasoline inside the filter and it needs to be drained into a container.

Installing a new fuel filter on a Chevrolet Niva is carried out in the reverse order. In this case, you need to pay attention to the arrow drawn on the body - it must be directed towards the front of the car (along the direction of the fuel supply).

1. When putting on the tips of the fuel pipes, clicks of the clamps should be heard.
2. When everything is done, all that remains is to turn on the ignition and inspect all connections for leaks.
3. At this point, replacing the Chevrolet Niva fuel filter with your own hands is completed.

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:

• It feels difficult to operate the engine when moving up;
• Extraneous noise is clearly audible when the engine warms up;
• Fuel consumption has increased;
• The car engine starts with difficulty or does not start at all;
• The motor runs with long jerks.

The first thing to do if these signs are present is to check the filter. However, even if you have not noticed 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.

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.

Purpose and signs of need for replacement

The main purpose of the fuel filter is to clean the fuel coming from the car’s tank through the fuel lines. Any fuel, no matter how much it costs, contains many foreign particles, dust, dirt, water and other substances. To prevent these substances from entering the cylinder, a special cleaning filter is installed along the way.

In order to improve the quality of purification of various impurities in fuel, two types of products were created: fine and coarse purification. Let's look at what they are intended for next.

The coarse cleaning product is designed to capture particles whose size is up to 0.1 mm. This product has the shape of a mesh, which is made of brass material. The coarse cleaning device on the Niva Chevrolet SUV is installed directly in the fuel pump.

The fine cleaning device is used to clean fuel from impurities up to 0.001 mm in size. It is a cylindrical base, inside of which there is a mesh with small fractions (cells). This product is located in the fuel system of the car between the ramp and the fuel pump. If it becomes clogged, it must be replaced. The coarse cleaning product can be washed, so it does not need periodic replacement.

It is also worth noting that in Chevrolet Niva SUV models before 2009, the fine fuel filter is located under the hood in the engine compartment. Newer (restyled) Chevrolet Niv models, which have received a new design from Bertone, are equipped with a product located under the bottom. Let's consider the process of replacing a filter for Niva Chevrolet cars from 2009. Replacement of the product for models before 2009 is carried out in the same way.

Unscrew the protective screen

The following characteristic signs indicate that a product needs to be replaced:

1. When moving up, the engine feels difficult to operate;
2. The presence of extraneous noise when the engine warms up;
3. An increase in fuel consumption is noticeable.
4. The car engine does not start or starts with difficulty.
5. The unit operates jerkily.

Removing the protective cover

If such factors are detected, the fuel cleaning device should be replaced. Another sign that indicates the need to replace a product is mileage. Approximately every 10-15 thousand km the fuel purifier needs to be replaced.

Replacing the device for restyled models

On the Chevrolet Niva SUV since 2009, the fuel filter has been located under the bottom, or, more precisely, under the right rear wheel, which is covered with a casing. Based on this, repair work should be carried out in an inspection hole or overpass.

Release the filter from the mount

You can check the presence of pressure in the system by unscrewing the cap of the fuel rail fitting and pressing the spool rod. If it is necessary to relieve pressure, then the following steps are performed:

• Inside the car, you must install the rear seat cushion in a vertical position. There is sound insulation under the pillow, which should also be unscrewed.
• Under the silencer there is a cover, which is fixed with two self-tapping screws. These screws need to be unscrewed and the cover removed.
• Under the cover there are blocks with wires from the fuel module. To relieve pressure in the system, you need to disconnect the pad clamps and start the engine. We leave the engine running until it stalls on its own. Now there is no pressure in the system and you can start replacing the filter.

Disconnect the fuel pipes

Let's begin the replacement process:

We lower ourselves into the inspection hole and, using a “10” key, unscrew the fastenings of the protective casing. The casing is removed. The tip is removed from the filter fitting by squeezing the two clamps of the outlet tube. Using a key set to “10” loosens the clamp that secures the filter. The clamps on the conductive tube must be compressed and the filter moved until it is removed from the fastening with the clamp

The device contains a certain amount of fuel, which is carefully drained into a container

On pre-restyling Shnivys, replacement is carried out in the same way, only the filter is located under the hood, on the passenger side. To replace it, you must follow the same steps for replacement, except for removing the protective cover - which is not there.

Now the new fine filter is installed in the reverse order of removal. Don't forget to point the arrows on your device in the correct direction. Based on all of the above, it should be noted that replacing this product does not require special skills and is carried out within 20-30 minutes, which makes the process even more enjoyable.

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.
