Noise isolation of the engine compartment vw polo sedan with ABS
Good day, long time ago I promised the guys to describe the principle of installation noise isolation standard engine on our polo which has ABS, I say at once it is not easy, as this noise in the factory put when there is no any tubes and so on.
For those who have a car in the base already has a description of engine sound insulation, there to do everything much easier, and with additional noise the effect is even better. www.drive2.ru/cars/volksw…/vyksa-2/journal/1932276/ www.drive2.ru/cars/volksw…/vyksa-2/journal/1952260/
What you need for this: www.drive2.ru/cars/volksw…abitlord/journal/1888325/ read this post and buy
6R1 863 353 E – noise insulation of the engine cover (engine compartment) – 2484 rubles 6R6 863 993 C (6R6 863 993D) – Noise isolation of air ducts (engine compartment) – 1246 rubles N 903 350 05 – Clamping washer – 63 roubles (5 pcs.)
All prices changed long ago …
6Q0 863 829 – Noise insulation for brake booster – no need to buy this one as it is not realistic to install it without removing the brake cylinder
Then we go and wash the engine with steam and dry it all (I didn’t manage to wash the engine, because the nearest washer that could do it was in 300 km)
We start with the fact that remove terminals from the battery then remove the wipers (peel off plugs, unscrew screws and then using WD40 dorastaem them ) Then remove the plastic apron (gently pry it and pull out of the clip that goes along the window)
After removing the box of the air filter, in order to reach the screws and remove the drainage.
Next remove the engine control unit (unbuckle at the top of the plastic bracket, then remove the fasteners of the plastic substrate under the control unit).
Further we unscrew the drain (on it I also separately glued a desiccant).
And further, the most difficult begins, it is possible to remove completely control block ABS, but I did not begin to risk and have decided only to take off tubes from fasteners and to unscrew these fasteners.
here are mounts of tubes from which it is necessary to take out tubes, and then to unscrew these mounts.
Next, take a large sheet of noise and cut it into two halves, so that in the middle were the tubes of climate control (and who has air conditioning)
1) the place which I have already been cut 2) the place which cut 3) the piece is removed because it just covers the tube climate or air conditioning
I started with something easier, the first I began to poke through the half which is located under the brake cylinder, as it is much easier to do there, all poked his hands around and how to torture and matami did it and installed, all was harder to stick noise under the tubes which were under the block, I had to bend and suffer, and use an additional tool, pushing and pulling noise out of the tube.
It was much harder for me to get the second sheet through, I thought for a long time how to get it through and under, no matter how I tried, it did not work. Then after much deliberation, I decided to bend in two halves, so that the aluminum was inside the bend, the whole thing is passed under the tubes from the ground, then fit one side to the tubes air conditioning, and all docked, further, there was agony on unrolling folded noise under these tubes, was tortured swearing, called my brother, something he helped me do, voila, everything was done, shrunk into place, the metal foil was partially straightened.
Next is the reverse process, screwing mounts for the tubes and installing them. No additional fasteners are needed here because everything is firmly attached.
If you want, you can fix a joint near the air conditioner tubes, if you want you can sew them with a metal wire, but I don’t think it will be needed.
And then everything is simple, assembling back, we put the drainage system, on top of it we fix noise of the drainage system, fix it with washers, install the engine block and so on.
PS. all this took about 2 – 3 hours, not reading the fact that the car before installing noise for 24 hours (it was already cold), and wash everything just a sink could not, you need warm steam with chemistry.
PS2. The noise is less. No more ringing of the engine after you press the gas to the floor. about 4 thousand revolutions, as before at 3. But again, I can not be sure, since this summer, even before that (about 3 weeks) did a full noise underbody and trunk in the car.
Now with what was, just can not compare.
PS3. Those who do not have ABS, I recommend gluing another sheet of noise for a better effect.
Independently do noise insulation of the engine compartment of a Volkswagen Polo sedan
Neither Carl Benz, nor Gottlieb Daimler or Wilhelm Maybach could ever assume that in the future their world-famous inventions would become not just unique means of transport powered by the internal combustion engine, but also examples of luxury and unimaginable comfort.
Comfort and convenience are some of the main criteria that determine consumer choice in today’s automotive market. Every specimen of the automobile industry should not only have an attractive appearance, but also have a roomy ergonomic interior with a rich selection of options, first-class trim and chic soundproofing.
However, not all models can boast a decent level of noise insulation. “Crickets”, squeaks, crackles, humming of the engine are everyday problems for many cars. Some people try not to pay attention to extraneous noises in the cabin, while others try to remedy the situation by installing layers of noise insulation in the cabin.
Volkswagen Polo sedan is a standard “budget” car, assembled according to the German technology by Kaluga masters. Like the majority of inexpensive models, the car also has difficulties to absorb noises. Manifestation of “crickets” is certainly an unpleasant moment, but the greater discomfort is caused by engine noise, which grows with speed and revolutions.
The basic part of noises falls on a power unit. The fact is that in Volkswagen Polo the partition which separates the engine from the interior is too thin and has no soundproofing materials. It is not surprising that many owners of Polo sedan become annoyed by the excessive rumble of the unit.
Most motorists go to special service centers, engaged in the installation of noise insulation, or “noise” in common parlance. Basically, they order complete insulation. This includes both covering the entire interior and individual body elements (wheel arches, hood, etc.).
The most difficult type of work is the installation of “noise” in the engine compartment. Workshops can charge up to 5000 rubles for the work plus the purchase of the necessary materials. The difficulty is usually associated with disassembly of the dashboard, under which there are many elements of electrical wiring. However, the installation of noise isolation on the Volkswagen Polo can be carried out without removing the “dashboard”.
The composition and material of the “noise”
What is noise insulation? It looks like a two-layer cake. The lower part is special materials that reduce vibration. It “gets stuck” in the structure of the composite, converting into thermal energy. The upper part performs a sound-absorbing function.
When choosing a soundproofing material, you should first understand that the engine compartment is a place where there are periodic leaks of various working fluids. Many composites can lose their original appearance because of the poisonous fumes, and all the work done will go to waste.
The most popular material for “noise” is Accent 10. It consists of a metallized film, flexible polyurethane foam and an adhesive mounting layer. Composite guarantees not only noise absorption up to 90%, but also retains heat well in the car. It is treated as a partition of the engine compartment, and the hood and trunk.
Installation of “noise insulation” on the Volkswagen Polo assumes the presence of certain tools. A standard set includes: a construction hair dryer, scissors, a knife for cutting, a dry rag, degreasing agent, a roller, a spatula.
The traditional scheme of applying “noise insulation” in the engine compartment includes two layers: vibration isolation and noise isolation.
If you have ventured to install noise insulation with your own hands, first of all, before the procedure it is necessary to determine the points on which you feel the strongest vibration. In specialized workshops for this purpose, they use devices that fix these points on the surface. In artisanal conditions, you can use old headphones from a music player or phone.
It is also necessary not to forget to prepare the work surface for the procedure: clean it from dirt and dust, and degrease it. Next, it is necessary to make blanks for insulation. To do this, you can use cardboard or sturdy paper. On them, you will be able to make the necessary cuts, which will allow you to perfectly place the composite on the surface. Do not be lazy to make a template, as the sample will facilitate further work.
The following materials will be required for the Volkswagen Polo:
- Noise insulation of the engine shield with the code number 6R1 863 353 E. This is an original part from VAG, which can be purchased at a price of 5000 rubles.
- Noise insulation of the box drain has VAG number 6R6 863 993 C. It costs from 3000 rubles at online stores.
- Clamping washers VAG N 903 350 05 in quantity of five pieces (at a price of about 50 rubles/piece).
Installing the noise insulation of the engine with your own hands
Sequence of actions to install “noise insulation” on the Volkswagen Polo:
- Remove the terminals from the battery. Remove plugs, unscrew bolts, treat with “Vedeshkoy” and remove.
- Detach the plastic “apron”: first you need to pick up something sharp edge of the part, and then, overcoming the resistance of locks on the windshield, remove the panel.
Independent work will take about three hours, depending on the skills of the car owner. If the Polo sedan has no ABS system, another sheet of “noise insulation” (if available) can be placed under the control unit.
Soundproofing overlays can not only significantly reduce the noise level in the interior of the Volkswagen Polo, but also make the movement of the steering wheel stiffer and more accurate. The vibration on the “steering wheel” at high speeds also decreases.
In addition the specialists advise to install a layer of “noise” on the dashboard in order to enhance the effect of noise absorption. But it is better to deliver this delicate and laborious business in hands of professionals.
