The Chevrolet Niva is one of the first AvtoVAZ production models to which a cabin filter was installed from the factory. This element plays an important role. About its device, varieties and replacement - further in our article.
Appointment
During operation, even with the stove and air conditioning turned off, a lot of harmful substances get into the car interior. This is not only the exhaust gases in front of the going cars, but also soot, road dust. All this is captured by the air intake and enters the cabin. To ensure clean air, a cabin filter is located on the Chevrolet-Niva car between the engine compartment and the vents. Replacing this element strictly by resource is the key to the health of the driver and passengers. After all, this element performs an essential function - it prevents the penetration of carbon monoxide and other harmful substances into the lungs during movement. It is also called an air conditioner filter.
In general, this element is installed on cars from the beginning of the 90s. But in connection with the restructuring, improvements to domestic cars touched only after cooperation with GM. AvtoVAZ, together with the Americans, released a new model of an SUV that advised all technical and environmental standards. On simple "Niva" of that time, the installation of a cabin filter was not provided.
Varieties
There are several types of air purification in the system:
- Mechanical In this case, the air is cleaned through paper thin fiber material. We will consider its device below.
- Adsorption . Such filters clean more efficiently through the use of activated carbon. It perfectly eliminates all bacteria and odors that enter the salon. In the manufacture, the adsorption element is applied to a synthetic or textile base. Compared to mechanical, this element purifies air 5-10 times better. Charcoal is used as a base.
Device
This element consists of a paper base and includes several layers. The top serves to retain large particles - up to 15 microns. Underneath is an electrostatic layer. He already copes with small dust particles.
Further, when it comes to an adsorption filter, a layer based on activated carbon is provided. And the last, fourth layer, serves for the final filtering of elements that the previous three could not hold.
Location
Where is the cabin filter on Chevrolet Niva cars? It is located at the intersection of the cabin and the engine compartment. It is located in the center and placed in a plastic case.
Resource
How often to change a cabin filter on a Chevrolet-Niva car? The replacement of a multilayer element should be made every 35 thousand kilometers. But you need to consider the operating conditions. If the car often drives on the road (for which, in fact, it is bought), this period can be divided into two. Indeed, on rough terrain, the concentration of dust is many times higher than that usually in the city and on the highway.
Symptoms
How to understand that the cabin filter is dirty on a Chevrolet-Niva car? Replacement of this element is necessary if the air flow from the stove suddenly decreases. If the machine is equipped with air conditioning, a characteristic smell of mold will be released along with the air stream. If you do not replace the element in time, you will need to clean the radiator of the air conditioner. In rare cases, airflow attenuation occurs due to a broken stove motor. But first you need to check the cabin filter on a Chevrolet-Niva car. Replacing this element in 80 percent of cases eliminates this malfunction. With the above symptoms, always check the element for contamination.
Replacement
You can do this procedure yourself on a Chevrolet-Niva car. Car service for this work will take about 500 rubles. To replace it with our own hands, we need a new filter, a negative screwdriver and sealant. Open the hood of the car and find the body of the element. It is closed by a lid. Using a screwdriver, we pick out the element and clean it from the old sealant. You should also clean its remains on the case itself. On some modifications, the lid is additionally fixed on a self-tapping screw. Here you will need a Phillips screwdriver. If the sealant is very dry and the cover does not come off, you do not need to exert any force - this will damage the element. Gently pry the edges around the perimeter. In extreme cases, heat it with a hairdryer. After that, we remove the dirty filter element out and install a new one.
Due to its rectangular shape, it is very difficult to mix up its location. It is located with a foam edge to the top of the hood. After that, we lubricate the sealant around the entire perimeter of the lid and install the element in its place. To prevent further dismantling, use silicone sealant. It provides reliable protection against external factors, while easily being removed on a plastic surface. Dries about a day. This completes the
replacement of the cabin filter for the GM-AvtoVAZ car. As you can see, everyone can handle this. Clean and fresh air will fall into the cabin again. By the way, the photo below shows how the old and new elements look.
As you can see, the degree of pollution is significant. Especially often it is polluted in the May period, during poplar fluff.
Therefore, some car owners install an additional mosquito net on its surface.
Is it possible to restore the old?
It should be noted that the cabin filter, whether it is mechanical or adsorption cleaning, cannot be restored. Blowing and flushing the element with water will not help. You may be able to remove some of the dust, but there will be no effect from the work - dirty air will still enter the machine. Also, any mechanical interference damages the layer and the internal structure of the filter. It costs inexpensively - about 300 rubles. Therefore, it does not make sense to restore it.
So, we found out where the cabin filter is on the Chevrolet Niva car and how to replace it.
