Air filter on UAZ: what is useful for a car owner to know?

The purpose of the air filter is to clean the air flow entering the internal combustion engine. When dirty air enters the engine, the operation of the unit may be disrupted; to prevent this, UAZ vehicles are equipped with a filter element. From this material you will learn what kind of air filter is installed in the UAZ, what functions it performs and what the element housing consists of.

Description of the air filter

The air filter in the body of a UAZ car is installed in the engine compartment, not far from the radiator. We are talking about both traditional UAZ models, referred to by domestic motorists as “loaf”, and Patriot SUVs. In fact, the air filter (hereinafter referred to as the air filter) plays a rather important role in the functioning of the engine. After all, if an element fails or is contaminated, engine operation will be incorrect, and in some cases, completely impossible. Therefore, attention should be paid to the performance of this component from time to time; you can learn more about the design and functions below.

UAZ air filter in the housing under the hood

In total, there are several types of air filters, but UAZ cars are equipped with inertial oil VFs. As operating practice has shown, such filter elements in a metal casing work much better compared to traditional inertial ones. They have more improved cleaning characteristics, but today they are already considered quite outdated. However, they are actively used in the production of domestic vehicles.

The main function of the air filter on a UAZ car is to pass air flow through itself and clean it from dirt, dust and other impurities. If the air is not properly cleaned, impurities will accumulate, resulting in irreparable damage to the internal combustion engine. Accordingly, the main purpose of the VF is to clean the air and prevent dirt from entering the internal structure of the motor.

Another function, which is considered a consequence of the previous one, is an increase in the operating life of the entire system. This is achieved due to the fact that harmful impurities, which can cause incorrect operation of the internal combustion engine, are not allowed inside the engine housing with the proper level of cleaning. Of course, if the air filter on a UAZ is clogged, then there can be no talk of any protection.

Design

Let's move on to the design of the VF. As mentioned above, the UAZ air filter is installed in the engine compartment, next to the cooling radiator. The VF is mounted in a special metal casing that protects the part from external influences and mechanical damage. The filtration element itself is a cylindrical part. There is also a pipe installed on the top of the metal body. The housing itself is installed using a special clamp located at the bottom. Depending on the UAZ model, the body can be secured with either one or two clamps.

It should also be noted that the housing of the filter elements itself must be securely installed. If the clamps are not fully secured, this may cause extraneous sounds coming from the engine compartment. In practice, many UAZ owners turn to service stations with a similar problem; as a result, it turns out that the source of the noise is simply an incorrectly installed VF housing.

Air filter cross-section showing all layers

The air filter is made in a cylindrical shape. The basis is a tube, which is surrounded by a layer of special filtered paper. This layer is fundamental for air filtration. The lower part of the VF is closed with a lid, and a rubber sealing ring is located on top. In addition to filter paper, the upper part of the VF is equipped with a special rim - a shell.

UAZ vehicles are equipped with domestically produced VFs produced in Livne, Oryol region. Since such parts are installed on new vehicles initially, it is advisable to take this into account when purchasing.

The dimensions of the standard part for Russian-made cars are as follows:

The width of the purifier is 18.2 cm;
part height - 24.85 cm;
outer diameter is 8.65 cm;
As for the internal diameter, it is 1.05 cm.

Recommendations for use

What UAZ owners need to know about the operation of filter elements:

Always replace this part in a timely manner. Experts recommend carrying out this process every 10 thousand kilometers, maximum - every 15 thousand. Accordingly, depending on how often you use your vehicle, the VF should be changed at least once a year. In fact, the process of replacing a part is not particularly complicated and should not cause difficulties. And keep in mind that if the replacement is not done in a timely manner, the car’s engine will quickly heat up, power will drop when driving, extraneous sounds will appear, and fuel consumption will increase. Accordingly, such problems can be prevented by changing the VF in time.
Use only original products. If the VF is of dubious production, then it is far from a fact that it will be able to efficiently perform all the functions assigned to it. Today, the cost of the original is about 400 rubles; you must admit, this is not much for high-quality filtration.
Monitor the condition of the VF in a timely manner - this is an integral part of the maintenance and diagnostics of the part. Therefore, pay attention not only to instrument readings, but also to characteristics and other parameters that can be determined visually. With timely inspection, you can avoid problems such as wear of housing clamps, loose fit of the structure, etc. When replacing, always leave a note, in a notebook or on the VF itself, at what mileage it was replaced.
Make sure that the element is securely sealed. If there is no tightness, this will lead to contamination of the air duct. Dirt will also collect on the fan blades and other system components. This can be determined both as a result of inspection and after measuring operating pressure indicators. As a rule, problems with tightness arise as a result of incorrect installation, wear of the o-ring or its absence.
Be careful when replacing - in practice, this problem happens to many domestic motorists. When a part is changed, before dismantling the spent HF, it is necessary to clean all surfaces that are located next to it as efficiently as possible. Otherwise, dirt may remain and get into the new VF, so take the time to clean it.
To avoid damage to the rubber seal, it is advisable to lubricate it with a drop of motor fluid before installation. Otherwise, if the temperature under the hood is very high, the ring may be damaged if it comes into contact with metal.
Do not overtighten the VF during installation. Tighten the part exactly as many turns as recommended by the manufacturer. On average, three to four turns will be enough.
Do not listen to the recommendations of those who advise cleaning the VF and reusing it. As a rule, this is stated by people who lived at a time when air filters were in short supply and it was difficult to buy them. But now it is not at all advisable to do this. A contaminated air filter cannot be restored by any regeneration, and cleaning it with your own hands can cause damage to the filter layers. Therefore, it is better not to save, especially since 400 rubles is not such a large amount for which it is worth putting your “iron horse” in danger. We hope our recommendations will help you use VF correctly.

How to choose a filter?

The role of the air filter in the overall performance of the vehicle cannot be overestimated. The main function of the designated auto spare part is to filter the microelements entering the UAZ 409 “loaf” engine from outside. Another equally important function is to protect the tank where the fuel is located from contamination. If the air purifier malfunctions or is not replaced in a timely manner, the likelihood of failure of the engine of the UAZ 409 “ loaf ” vehicle and the occurrence of related breakdowns significantly increases.

The process of replacing the air filter does not take much effort and time, so even an untrained car enthusiast can cope with this action. First of all, the car enthusiast needs to familiarize himself with information on how to choose the right air purifier for the UAZ 409 “ loaf ” car. This is because the process of choosing the right air filter is essential to achieving a positive result in the end. Purchasing a filtering auto part that is not suitable for the UAZ 409 “loaf” car will affect not only the financial situation of the car owner, but can also negatively affect the further operation of the engine and the car as a whole.

Today there are available types of filters on the market that differ in shape, air purification method, classes and filter materials.

The first class includes expensive air filters that provide maximum engine protection;
The second class of air purifiers retains contaminants larger than 1 micron;
The third class of filter parts has a coarser throughput.

The shapes of air filters are:

Round;
Square;
Rectangular.

Based on the type of air purification, the following types of air purifiers are distinguished:

Inertial. They have a complex design with an oil tank. Contaminants entering the filtering auto part adhere to the oil surface and remain on it;
Cyclonic. These types of air filters operate based on centrifugal force. Dust and dirt particles are deposited in garbage receptacles;
Direct flow type. It is the most effective because it has less resistance to incoming air.

Materials used in air filters for air purification:

Paper. The most common material for creating an air filter. The paper has a special porous surface and is placed in the frame of the filtering auto part in the form of an accordion. Does not interact with moisture, since this type of air purifier does not have special impregnation;
Cotton fabric. The material is impregnated with a special liquid and folded into the air filter housing in the form of a corrugation. It cleans the air qualitatively due to the fact that contaminants remain not only on the surface of the part, but also inside;
Synthetic fibers. It is the most durable material, which increases its service life;
Gauze material. It is placed in the air filter housing in several layers and impregnated with oil.

In total, today there are a significant number of air filters that differ in different parameters. Cars of the UAZ 409 “loaf” model are in most cases equipped with inertial oil air cleaners. However, if the car has been modified, the air filter model may differ, so before replacing the part, it is important to familiarize yourself with its parameters.

The air filter on the UAZ “loaf” machine is usually made in the form of a cylinder, based on which paper is used to purify air coming from outside. The lower part of the air cleaner is closed with a lid, and there is a rubber O-ring on top. When replacing the air filter on a UAZ “loaf”, it is important to take into account that a domestically produced air cleaner is not always installed on the car.

Parameters of standard filter auto parts for the UAZ 409 “loaf” car:

Air purifier width - 18.2 cm;
The height of the air filtering part for the UAZ “ loaf ” machine is 24.85 cm;
The outer diameter of the auto part is 8.65 cm;
Inner diameter - 1.05 cm.

Air filter UAZ Bukhanka

Such vehicles, as a rule, are usually operated in difficult conditions - dusty, dirty roads, high temperatures. Therefore, the air filter becomes unusable relatively quickly.

It is advisable not to wait until the mileage is reached at which the car manufacturer recommends changing the filter component (10-15 thousand km). The condition should be monitored every 2-3 thousand km - a porous filter material clogged with dirt will cause increased fuel consumption and other problems.

Which air filter is better to choose: original or analogue

There is a wide selection of different automobile parts on sale. Therefore, buying a new filter will not cause big problems.

However, as with all other automobile parts, the buyer is faced with the problem of choice: original or analogue? Each option has its advantages and disadvantages.

Original filter for UAZ “Bukhanka”

One of the main advantages of the original is 100% compliance with the declared dimensions. There are no problems associated with the installation. Standard overall dimensions:

outer diameter, mm – 156;
internal diameter, mm – 72;
height, mm – 150.

Often analogues differ in size for some reason. Which leads to installation difficulties. Bends and folds appear on the filter element.

The consequence is a deterioration in air permeability and other problems. Consumption increases, efficiency decreases. By purchasing an original filter, the client does not have to worry about this - there is no need to modify the part manually.

UAZ "Bukhanka" with engine 409 is equipped with an injector. Therefore, the filter resistance coefficient significantly affects the motor power.

Recommendations for use

Air filter

on UAZ: what is useful for the car owner to know?

Description of air filter

UAZ Patriot air filter replacement

An air filter is a device that is designed to purify the air entering the vehicle’s power unit. To keep the air clean, the consumable (filter) needs to be changed periodically. Otherwise, the proper functioning of the engine may be affected, including engine malfunction.

Characteristics

The air filter of the UAZ Patriot SUV is located in the engine compartment in the radiator area. It is closed by a metal case. The main fastening is one or two clamps (depending on the engine installed in the UAZ Patriot).

The UAZ 3163 SUV with the ZMZ-409 power unit is equipped with Livny consumables. The dimensions of the device are as similar as possible to the original filter.

When to change?

The filter on an SUV needs to be changed every 10-15 thousand kilometers. If within one year the owner has not crossed the recommended mileage mark, it is advisable to change it once a year.

If you neglect this rule, the power unit will heat up, lose power, produce unpleasant noises and increase fuel consumption.

How to change?

To replace the filter element, you should prepare the following tools:

12mm wrench (socket or socket);
key to 17;
screwdriver (minus; flat).

Replacement procedure:

The first step is to turn off the power to the engine. To do this, remove the battery terminal.
Using a pre-prepared key, remove the clamp that holds the steel housing of the filter element.
Then the bolt that holds the clamp is unscrewed. The pipe, which is attached to the steel body, is moved to the side.
The air filter housing is removed from the engine compartment.

The procedure for removing the filter element from the housing:

Using a 17mm wrench, unscrew the cover securing nut.
The cover is removed together with the filter element. The internal space of the case and consumables are carefully analyzed. Perhaps it is not very dirty and can still be used. If it is sufficiently dirty, it should be changed at shorter intervals of kilometers traveled.
If replacement is required, the nut securing the cover together with the filter element is unscrewed.
The old consumable is replaced with a new one. You must first clean the interior of the case from contamination. To do this, take a rag and wipe it dry;
The procedure for replacing consumables should be carried out in reverse order.

Replacing air filters on UAZ other models has a number of features. Several of them will be discussed below.

Replacing the air filter on a UAZ 409 is carried out according to the following principle:

Preparation stage . The necessary tool is prepared, the vehicle is de-energized, and then the clamps are loosened with a key. They serve directly to hold the body.
Replacement stage . The housing fastenings are unscrewed using a 17 key. Removed from the engine compartment and the entire structure is inspected. The old filter is replaced with a new one (if necessary).
All elements are assembled in reverse order.

Replacing the air filter on a UAZ Hunter is done as follows:

First you need to turn off the car engine. To do this, disconnect the terminal from the battery;
An air-conducting sleeve is attached to the filter element housing. It is attached to a clamp. Its bolt must be loosened and the sleeve disconnected from the air filter pipe;
then you will need to remove the housing itself. To do this, loosen the clamps and remove the air filter from the vehicle;
The air filter is installed, and then all the elements are assembled in the reverse order.

The replacement instructions for other UAZ models are similar. The only difference is the location of the filter element due to the location of the power unit.
