The car "Chevrolet Niva" replaced the VAZ-2121 and its modifications as a more advanced model. Having retained the excellent off-road characteristics of the Niva 4 × 4 and having acquired a new appearance, he began to be in demand among people who value comfort.

Together with the improvements, a number of shortcomings typical of domestic cars migrated to the new model. Including noise in the cabin. This article will tell you how to soundproof a Chevrolet Niva.

Why soundproofing

A running car engine is the main source of noise in the cabin. The higher the engine speed, the higher it is.

During the movement, new sources are added:

• noise from tires buzzing at speed;
• deflectors on car doors;
• poor aerodynamics;
• poorly fixed plastic skins,creaking as they go.

All this is very annoying, shaking the driver's nervous system and reducing traffic safety.

Another reason for installing soundproofing in the Chevrolet Niva may be the desire of the car owner to make high-quality audio preparation. In this case, the glued body metal will not be a conductor of sound waves, and they will not leave the cabin.

How to make a soundproofing "Chevrolet Niva" with your own hands

You don't have to be a repairman to soundproof your car. It is enough to be able to handle a simple tool, such as screwdrivers, a building hair dryer. Additionally (but not required) you will need a car clip removal kit. It is inexpensive. Its price can offset the cost of new clips that you don't have to buy.

In order to soundproof the Chevrolet Niva, you will have to disassemble the interior of the car:

1. Remove the ceiling.
2. Remove door skins.
3. Disassemble the engine compartment insulation.
4. Remove seats and interior floor trim.
5. Remove luggage compartment side trims.

None of these operations is difficult. Only the amount of work can scare you. Dismantling is best done in a garage or some other room. The working time for one person will be about 2-3 days. However, the sound insulation of the Chevrolet Niva can be done in stages, breaking up the process. One day - to glue the doors and the trunk, the second day to devote to the ceiling, the third to deal with the floor and the engine compartment. In this way,the car will be on the move all the time.

Chevrolet Niva soundproofing reviews are the most positive. After the work done in this direction, you can calmly talk while driving at a speed above 90 km / h, without raising your voice.

Removing headlining

The headlining is attached with 3 passenger handles, 2 sun visors, lighting dome, 2 clips fixing the trim in the rear in the center. Also, it is additionally held by plastic facings of the middle pillars, plastic edging of the rear windows.

To remove the ceiling, you need:

1. Remove the trunk seal.

2. Remove sun visors. To do this, 6 bolts are unscrewed with a Phillips screwdriver. Four of which hold the visors, and two attach plastic hooks-clamps.

3. Remove light cover. To do this, the transparent part of it is pryed with a screwdriver and the latches are carefully snapped off. A bolt will be found under the glass, pressing the cover to the body.

4. Remove the three handles located on the ceiling opposite each of the passenger seats. To do this, on each of the handles you need to remove 2 plugs that will open access to the bolts. They should be unscrewed.

5. Using two screwdrivers, remove the clips that secure the ceiling at the rear. Instead of screwdrivers, it is better to use special plastic spatulas or a clip remover, popularly referred to as a “clipsoder”.

The final part of the disassembly isremoval of the plastic edging of the rear windows and the plastic trim on the middle pillar. You can not remove it completely from it, but only unfasten the upper part and push it to the side. To do this, unfasten the upper seat belt loops by removing the plastic lining and unscrewing the bolts with a wrench.

To remove the rear glass bezel, you need to remove the plastic plug at the top and unscrew the bolt, then move the bezel to the side.

Now you can pull out the headlining. To do this, without wrinkling the edges, pull it out of the passenger compartment through the trunk door.

Roof pasting

In order not to stain the skin, it must be immediately wrapped with a film.

After the roof space has become available, you can start soundproofing the Chevrolet Niva.

Special materials for noise insulation have an adhesive base. The most common ones are:

Vibroplast Silver. Foil material on a self-adhesive basis. Coating thickness 2–4 mm. For gluing does not require heat. Sold by sheets

• "Bitoplast 5" (anti-creak). Made from polyurethane. It has a sticky base that does not require heating. Thickness from 5 to 10 mm. Designed to prevent noise and squeak.
• "Splen 3004". Since this material is heat bonded, it can be used in places such as wheel arches, transmission tunnel.

Before gluing soundproofing, wipe the surface with a damp cloth, then degrease it. First you need to gluethe main part of the roof with whole sheets of soundproofing material, then glue the perimeter in separate pieces.

Material on the roof takes about 3 square meters. m.

After pasting the roof, the ceiling sheathing is installed in the reverse order.

Dismantling doors

The front and rear doors are disassembled the same way, except that there are power windows in the front and manual windows in the back. Since the driver's door is the most difficult to remove the skin, we will analyze it with an example:

1. Remove the two screws that secure the door handle. They are hidden by stubs. You need to pry them with a flat screwdriver and pull them out.

2. Loosen the five screws around the perimeter. Two are in the front, the rest from the bottom fix the skin pocket. In this case, a regular screwdriver will not work. Need a hexagon.

3. Remove the handle trim. To do this, you need to take it aside and unscrew the bolt behind it.

In addition to the fasteners, which are visible, inside the casing is fixed with clips around the entire perimeter. To unhook them, you need a clipper. Or a large flathead screwdriver.

To pull out the clips, you need to pull on the trim and insert a clip remover or a screwdriver into the gap. They need to get between the clip and the hole in which it sits. Using the tool as a lever, release the clip.

After all the clips are disconnected, the casing continues to hang on the wires that are connected to the buttonswindow lift control. They need to be pulled out of their sockets.

Behind the skin, the door is pasted over with a film that prevents dust from entering inside. It must be carefully cut, but not thrown away, but glued back before assembly.

A strip of special material is glued as a factory soundproofing for Chevrolet Niva doors. However, it is not enough. To reduce the penetration of noise, you need to completely paste over the inner plane.

Glue rear wheel arches

Wheel arches make a significant contribution to the overall noise. It is they who receive acoustic vibrations from tires and transmit them to the cabin. Therefore, the arches must be insulated.

In the cabin, they are closed with a factory carpet and insulation in front, with side trunk linings in the back.

To gain access to the rear wheel arches, you need to raise the rear seats to the position for transporting bulky goods, remove the rear shelf, pull the trim from under the door rubber bands. Then pull out the clips that secure it.

Glue front wheel arches

The situation is more complicated with the front arches. The fact is that the insulation that covers the motor shield from the inside also closes the arches. Therefore, in order to gain access there, you must either completely remove the instrument panel, or cut off a piece of insulation.

Dismantling the instrument panel is a somewhat laborious process, but there is no need to be afraid of difficulties. All wires are connected only to their connectors, and it is difficult to confuse anything.

From the sides, the carpet is attached with plastic thresholds, removing which, you can openfront fenders and engine shield.

It is better to use thicker material for gluing the front shield. This place is the source of the biggest noise.

Bottom soundproofing

Soundproofing bottoms are approached in a slightly different way. It is good to isolate it with roofing building materials, which are heated with burners and create a molten layer. Only in the case of Chevrolet Niva soundproofing, a building hair dryer is used instead of a burner. This method, in addition to being cheaper, will help to additionally protect the bottom from moisture that accumulates during winter, when snow enters the cabin.

These materials easily take any shape when heated, and partial melting allows penetration into any gap.

Chevrolet Niva bonnet soundproofing

There is no need to further isolate the hood compartment from noise, because it has no points of contact with the passenger compartment. However, you can often see pasted hoods on cars. What is it for? To ensure faster heating of the engine compartment in winter, the hood is insulated with thick adhesive-based foil foam.

However, on the stock Chevrolet Niva, the engine compartment is already insulated with thick material, clipped onto the hood.
