The Chevrolet Niva replaced the VAZ-2121 and its modifications as a more advanced model. Having preserved 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 appreciate comfort.
Along with improvements to the new model, a number of shortcomings inherent in domestic cars migrated. Including noise in the cabin. This article will tell about how to make sound insulation of the Chevrolet Niva.
Why do sound insulation
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 siding creaking on the go.
All this is very annoying, shaking the driver’s nervous system and reducing driving safety.
Another reason for installing soundproofing the Chevrolet Niva interior may be the desire of the car owner to make high-quality audio preparation. In this case, the glued metal of the body will not be a conductor of sound waves, and they will not leave the cabin.
How to make sound insulation “Chevrolet Niva” with your own hands
In order to make noise insulation on the machine, it is not necessary to be a repair specialist. It is enough to be able to handle a simple tool, such as a screwdriver, a building hair dryer. Additionally (but not necessarily) you will need a kit for removing car clips. It is inexpensive. Its price can offset the cost of new clips that you don’t have to buy.
In order to make sound insulation of the “Chevrolet Niva”, you have to disassemble the interior of the car:
- Remove the ceiling.
- Remove the door trim.
- Disassemble the engine compartment heater.
- Remove the seats and the floor trim in the passenger compartment.
- Remove side trim for luggage compartment.
None of these operations are difficult. Only the amount of work can scare. Disassembly 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, fragmenting the process. In one day - glue the doors and trunk, dedicate the second day to the ceiling, and on the third to tackle the floor and the engine compartment. Thus, the car will be on the go all the time.
Reviews about the sound insulation of the Chevrolet Niva are the most positive. After the work done in this direction, you can calmly talk when driving at a speed above 90 km / h without raising your voice.
Removal of a covering of a ceiling
The ceiling cladding is attached by 3 passenger handles, 2 sun visors, a lighting lamp, 2 clips that fix the cladding in the back in the center. Also, it is additionally supported by plastic cladding of the middle pillars, plastic edging of the rear windows.
To remove the ceiling, you need:
1. To remove a sealing gum of a luggage carrier.
2. Remove the sun visors. To do this, 6 screws are unscrewed with a Phillips screwdriver. Four of which hold visors, and two fasten plastic hooks-clamps.
3. Remove the light cover. To do this, a transparent part of it is pryed off with a screwdriver and the latches are carefully snapped off. Under the glass there is a bolt that presses the ceiling 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, which will open access to the bolts. They should be unscrewed.
5. Using two screwdrivers, remove the clips securing the ceiling in the rear. Instead of screwdrivers, it is better to use special plastic blades or a clip-clipper, popularly referred to as a “clipper”.
The final part of the disassembly is the removal of the plastic trim on the rear windows and the plastic lining on the middle pillar. Completely from it is possible not to remove, but only to unfasten the upper part and move aside. To do this, you need to unfasten the upper loops of seat belts, removing the plastic lining and unscrewing the bolts with a wrench.
To remove the edging of the rear windows, you need to remove the plastic plug in the upper part and unscrew the bolt, and then take the edging to the side.
Now you can pull out the roof lining. 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 casing, you need to immediately wrap it with a film.
Once the roof space has become available, you can begin to soundproof the Chevrolet Niva.
Special materials for sound 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 heating. Sold by sheets.
- "Bitoplast 5" (antiskrip). Made of polyurethane. It has a sticky base that does not require heating. Thickness is from 5 to 10 mm. Designed to prevent noise and squeaking.
- Splen 3004 Since this material is glued by heat, it can be used in places such as wheel arches, the tunnel above the gearbox.
Before attaching noise insulation, wipe the surface with a damp cloth, then degrease it. First you need to glue the main part of the roof with whole sheets of soundproofing material, then glue the perimeter in separate pieces.
The material on the roof takes about 3 square meters. m
After gluing the roof, the ceiling cladding is installed in the reverse order.
Door disassembly
The front and rear doors are disassembled the same way, with the exception of the fact that there are power windows in front and manual ones in the back. Since the driver's door is the most difficult to remove the lining, we will analyze on its example:
1. Unscrew the two bolts that secure the door handle. They are hidden by plugs. They must be pry off with a flat screwdriver and pulled out.
2. Unscrew the five screws around the perimeter. Two are in the front, the rest on the bottom fix the skin pocket. In this case, a conventional screwdriver will not work. Need a hexagon.
3. Remove the trim on the handle. To do this, you need to take it to the side and unscrew the bolt located behind it.
In addition to the fasteners that are visible, inside the casing is fixed with clips around the entire perimeter. To unhook them, you need a clip clip. Or a large flat screwdriver.
To pull out the clips, you need to pull on the casing and insert a clip puller or a screwdriver into the resulting gap. They need to get between the clip and the hole in which it sits. Acting as a lever with the tool, squeeze the clip.
After all the clips are disconnected, the casing continues to hang on the wires that are connected to the power window control buttons. They need to be pulled out of their connectors.
Behind the casing, the door is glued with a film that prevents dust from entering inside. It must be carefully cut, but not thrown away, but glued back before assembly.
As a factory noise insulation of the doors of the Chevrolet Niva, a strip of special material is glued. However, it is not enough. To reduce the penetration of noise, you need to completely glue the inner plane.
Sizing rear wheel arches
The wheel arches make a significant contribution to the overall noise. They accept acoustic vibrations from tires and transfer them to the salon. Therefore, arches must be isolated.
In the cabin, they are closed with a factory carpet and a heater in the front, side lining of the trunk at the rear.
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, and remove the casing from under the rubber bands. Then pull out the clips that secure it.
Sizing front wheel arches
With the front arches, the situation is more complicated. The fact is that the insulation that closes the motor shield from the inside also closes the arches. Therefore, in order to gain access there, one must either completely remove the instrument panel or cut off a fragment of the insulation.
Dismantling the instrument panel is a somewhat time-consuming process, but there is no need to be afraid of difficulties. All wires are connected only to their connectors, and it is difficult to mix anything up.
On the sides, the Carpet is mounted using plastic sills, removing which, you can open the front arches and motor shield.
For gluing the front shield, it is better to use a thicker material. This place is the source of the biggest noise.
Soundproofing the bottom
The soundproofing of the bottom is a bit different. It is good to isolate it with roofing building materials, which are heated with the help of burners and create a molten layer. Only in the case of Chevrolet Niva soundproofing a construction hair dryer is used instead of a burner. This method, in addition to being cheaper, will help to further protect the bottom from moisture accumulating during the winter, when snow enters the cabin.
When heated, these materials easily take any form, and partial melting allows them to penetrate into any gap.
Soundproofing hood “Chevrolet Niva”
There is no need to additionally isolate the hood compartment from noise, because it has no points of contact with the passenger compartment. However, you can often see taped hoods on cars. Why is this done? To ensure faster heating of the engine compartment in winter, the hood is insulated with thick foil adhesive-based foam.
However, on the Chevrolet Niva in the stock version, the engine compartment is already insulated with thick material fixed with clips on the hood.
