Replacing the exhaust pipe vaz 2114

VAZ cars of the 14th and 15th models are still in demand among Russian drivers. Machines are unpretentious in operation, do not require vigilant attention and rarely need repairs. However, they also have a “sore” place - these are silencers. Therefore, the owners of the VAZ 2114/2115 need to be prepared for the fact that sooner or later they will have to repair or replace the "glushak" on their car.

What is a car muffler for?

Regardless of the brand and year of manufacture of the car, all its systems serve the same purpose - to ensure the stable operation of the engine and movement. The exhaust system may seem insignificant compared to systems such as brakes or fuel. However, it is the car's exhaust system that has the most direct influence on engine performance.

Silencer is an integral part exhaust system . Its main purpose is to remove exhaust gases from the machine. In addition, the part also serves to reduce noise, since fuel residues can burn in the exhaust pipes.

The pipe exits from the rear left side of the vehicle

How is it attached

The muffler on the VAZ 2114/2115 is attached to the car body. In order for the pipe to be securely fixed and not vibrate during movement, two methods of fastening are used:

bolted;

on rubber hangers.

Bolts and nuts for fastening muffler pipes are made of special heat-resistant alloys

Directly to exhaust manifold the silencer is fastened with bolted connections, which guarantee complete tightness of the joints. The middle part is also fixed with bolts and nuts. And the resonator and the exhaust pipe are hung on special hooks on the bottom with elastic bands. These suspensions are easy to put on and take off, but at the same time they provide a rigid fixation even when driving on rough roads.

Schematic arrangement of the exhaust system on the VAZ 2114/2115

The gas exhaust system VAZ 2114/2115 consists of several parts. By connecting to each other in series, all parts ultimately serve the same purpose - reducing noise and bringing exhaust out of the body.

1 - bracket for fastening the receiving pipe; 2 - gasket; 3 - clamping device for the bracket; 4 - additional muffler; 5.7 - "pillows" for the silencer suspension; 6 - main muffler; 8 - a clamp connecting the muffler pipes; 9 - neutralizing device; 10 - hinge seal ring; 11 - sensor that controls the concentration of oxygen in emissions; 12 - exhaust pipe for mufflers

How to replace a muffler on a VAZ 2114/2115

If any problems with the muffler have begun, then it is better not to postpone the matter indefinitely. The life and health of the driver and passengers depends on how well the Glushak works. In general, the replacement process itself begins with the selection of a new set of exhaust systems. It is best not to save money, but to purchase the original factory one. This will delay the need for re-replacement indefinitely.

For reliable operation, it is advisable to buy new rubber suspensions in advance.

What tools will be needed

To work, you need a simple set of tools:

two open-end wrenches for 13;

• brake fluid or WD-40 lubricant;

  screwdriver with a flat thin blade.

How to remove a muffler without a hole

The easiest way is to use a flyover or viewing hole- in this case, you can more conveniently crawl under the car body and carry out the necessary operations. However, drivers often do not have the opportunity to use such devices, so they use a conventional jack.

To remove the "glushak" from the VAZ 2114/2115, you must:

Jack up the rear left edge of the vehicle.

Make sure the machine is stable.

Get under the body and moisten all pipe and bolt connections with grease.

Wait 10-15 minutes for the liquid to be absorbed.

After that, you can begin to unscrew the bolted connections. If the bolts cannot be unscrewed with ordinary wrenches, it is recommended to cut them off with a chisel and a hammer. However, you must act very carefully so as not to hook the bottom.

After the pipe has been unscrewed, it remains only to remove the part from several rubber hangers. To do this, the body is slightly raised. If the rubber band is tight, then you can pry it with a screwdriver.

The dismantled muffler is pulled out from under the car.

How to install a new one and secure it correctly

Before proceeding with the installation of a new muffler, you need to clean everything strategically important places under the bottom: hooks for attaching rubber bands, brackets for bolts. The product is installed in the reverse order:

First, pull the muffler under the car body and place it in the position in which it will be fixed.

After that, hang the exhaust pipe and resonator on rubber suspensions. Make sure every connection is secure and the part won't slip off the hooks on the first road pit.

Lower the car off the jack.

How to repair a "glushak" with your own hands

The muffler on the "fourteenth" and "fifteenth" is considered one of the most vulnerable parts of the car. The point is that due to the impact high temperatures the metal quickly burns out, that is, the tightness of the system is violated. Therefore, the part must be changed as soon as there is a suspicion of its inoperability.

Reasons for failure

Most often, mufflers “burn out” - that is, due to hot exhausts, metal begins to thin inside the case, which ultimately leads to the appearance of holes. However, this is not the only reason why the Glushak can fail:

usage homemade device- handicraft products do not differ in quality and long service life;

mechanical impacts on uneven roads - dents and deformations of the pipe also lead to loss of tightness;

rust and corrosion affects even the highest quality original mufflers sooner or later.

In general, all of these factors to some extent affect the service life. The car owner can easily identify all of the above malfunctions - just drive the VAZ into the inspection hole and visually examine the muffler. In addition, when deformations, burnouts and corrosion reach their “peak”, the part will begin to emit when moving. characteristic sounds- gurgling, sharp pops, knocks.

Why is the muffler knocking

This part on the VAZ 2114/2115 can only make knocks in two cases:

it hits the body;

when moving, it touches the body of the gas tank.

In any case, you must immediately take measures to eliminate this malfunction. Most often, the problem lies in the strong wear of rubber suspensions. It is enough to change them and the muffler will again take its regular position under the bottom of the car.

Pendants are inexpensive, so you can buy new products without spending

In some cases, the "glushak" starts knocking when its elements were installed incorrectly - for example, after replacing the resonator or exhaust pipe. In this case, it will be necessary to once again check the correct installation of all fasteners and gaskets.

Citizens! It's simple! I knocked and I cured in five minutes! The pipes are connected with a clamp, and inside there is a spherical ring. But the connection is not mobile. By changing the angle between the pipes, in this connection, we change the center of gravity of the entire exhaust structure. You can also change the slope of the pipe arc, thereby moving it away from the gas tank. Experiment! Refurbishment is a scam! They will loosen the clamp, change the degree and charge you 800. Tough!

What to do if the "glushak" is clogged

During the operation of the car, dirt, soot, fuel impurities and other deposits will inevitably accumulate in the exhaust system pipes. Gradually, they, settling on the walls of the muffler, will clog its working space.

The driver can only notice this by the behavior of his car:

At first, when overtaking, it will be difficult to pick up speed.

Then even when uniform motion the car will have difficulty keeping the set speed.

Black exhaust from the pipe, loss of engine dynamics.

Cleaning the muffler is a tedious and long procedure. In addition, if the pipes are clogged, then, most likely, after cleaning, other defects will also be found - such as rust or burnouts. Therefore, it is more expedient to simply put a new one.

If the catalyst is clogged or the partitions in the muffler are destroyed and interfere with the exhaust, then after replacement it will certainly fly, and if nothing is clogged, then you won’t notice these 2 unfortunate horses at all.

Thermal insulation completely burnt out

The car owner needs to carefully ensure that the resonator coating is always tight. The barrel is covered with special thermal insulation materials, which sooner or later burn out during the operation of the machine. If you do not change the insulation in time, you will soon have to change the muffler itself.

To do this, the pipes are dismantled from under the car, separated in parts. A special heat-resistant cloth is glued to the surface, which can be bought at any car shop. This protection will provide more long term service and significantly reduce the noise of the motor.

How to put up a patch

Quite often, burnouts and holes appear on the muffler pipes. If the hole has not yet grown to a large diameter, it makes sense to weld it, that is, put a patch.

Having such extensive damage, the silencer is no longer repairable.

This will require a material identical to the pipe body and the skills of a welder. Before applying a patch, you need to qualitatively process the edges of the pipe: remove rust, clean the body to bare metal and degrease the welding points with a solvent.

The patch is superimposed on the hole (the patch should be at least twice the size of the hole in area) and tacked from several sides. After that, you can apply a weld. After the joint has cooled down, it is necessary to clean it of slags and paint the place of work with heat-resistant paint.

Thus, all work on the replacement and repair of the muffler can be done independently, without seeking help from specialists. The only difficulty can only be welding, since this will require both equipment and the skills of a welder.

In the terminology of drivers and car mechanics, the word muffler often means the whole complex of chambers and pipes that are part of the exhaust system of a modern vehicle hence the name - muffler resonator. Self-replacement of a faulty resonator is a rather laborious undertaking, but quite doable at home. It is worth noting that due to the design features of the resonator, it cannot be repaired, so the only way out in the event of a breakdown is to replace it with a new one. More on this later in the article.

Exhaust system VAZ 2114, what are the main parts of the exhaust system

The exhaust system on a VAZ 2114 car consists of the following main elements:

Additional silencer, or resonator 2114, what it is for, what tasks it performs

The resonator is the most important integral part vehicle exhaust system. Its main task is to reduce the noise level emitted by incoming exhaust gases. Its other, no less important task is to smooth out the vibrations that arise as a result of the tact of work. power unit, and the creation of direct flow of gases, which is necessary to prevent the appearance of back pressure in the exhaust pipe, since this would significantly reduce the power of the motor.

Structurally, it is made of four chambers through which perforated pipelines pass. They also perform connecting functions for the resonator chambers. As for perforation, it consists of holes of a specific, precisely calculated size. Pipes and chamber walls are a resonant pair that has its own frequency of oscillation, which differs from the frequency of oscillation of the exhaust gases. And the frequency data is different in each chamber. As a result, there is a smoothing of mass low-frequency vibrations, alignment of flow directions and damping of medium and high-frequency vibrations.

Symptoms of a malfunction of the additional muffler (resonator)

As a result of operation in such an aggressive environment (exhaust gases have an extremely high chemical activity and temperature) and under conditions of high vibration, the resonator often becomes unusable. Symptoms of such malfunctions are as follows:

Criteria for choosing a new resonator

Double-cased resonators will last the longest. It is important that the material is resistant to corrosion. Typically, inexpensive mufflers are made from aluminized steel, that is, ordinary steel coated with a small layer of aluminum, which protects the surface from corrosion. However, when buying such a resonator, it should be remembered that the low cost of the product is obtained by reducing the durability. The best resonators are made of stainless steel. An equally important role is played by the volume of the resonator. This indicator affects the efficiency of its work. When the volume is not enough, when you sharply press the gas pedal, the noise will increase significantly, and the element itself may begin to vibrate.

Workplace selection

Replacing the resonator with a VAZ 2114 must be carried out on a flyover or inspection hole.

Tools, fixtures, consumables

To replace the resonator you will need the following tools and fixtures:

1. Keys on "17" (two pieces).
2. Key amplifier.
3. New resonator gasket.
4. Sealing metal rings.
5. Clamps with fasteners.
6. Fluid WD40.

Pro tips: what parts are changed additionally when replacing a resonator

In the process of replacing the resonator, it is desirable to replace the rubber suspensions, which reduce the muffler vibrations when the car is moving.

The VAZ 2114 model is extremely convenient for motorists - parts for it can be found without difficulty. The exhaust system of this car has not changed much over the years - it is a curved or straight steel pipe and a muffler in the form of a cylinder.

The main components of the exhaust gas exhaust complex in Lada are:

• neutralizer;
• main muffler;
• gas receiving tube;
• additional muffler.

The gas intake pipe is attached to the converter using a movable hinge, which makes it similar to the VAZ 2109 exhaust system. Both mufflers are mounted to the bottom using rubber suspensions. Thanks to the suspension, vibration during transport through the exhaust gas system is almost not transmitted to the passenger compartment, which contributes to a comfortable ride. The muffler itself is designed to make exhaust sounds quieter, as well as create balance in the gas distribution system.

To ensure strong and tight fasteners, a graphite ring is mounted inside the flanges of the parts, and a gasket is provided above the converter to prevent excessive heating of the carrier body part. It performs a heat-repellent function.

However, the exhaust system is subject to the following problems:

• heating to high temperatures;
• frequent change of temperature regime (from heating to rapid cooling);
• corrosion affecting external and internal parts;
• mechanical damage;
• pollution and the action of abrasives from the side of the road surface;
• vibrations.

For these reasons, the exhaust system, in particular, the VAZ 2114 muffler, may become unusable. Due to the violation of the tightness of the system, the exhaust exits into the cracks that have formed, which makes driving dangerous.

You can identify a broken exhaust pipe by the characteristic loud pops, as well as changes that occur during engine operation. Sooner or later, even in spite of the repair, it is necessary to replace the exhaust. You can do this with your own hands, knowing the structure of the exhaust complex, or contact the professionals at the service station.

Exhaust types and structure

In a VAZ with a carburetor engine, the exhaust originates directly from the engine. A collector with a receiving tube is attached to it. A resonator is mounted to the product, which is connected to the muffler of the machine.

"Lada Samara", to which the above model belongs, can be divided into 2 generations:

1. The first is from VAZ 2108 to VAZ 21099.
2. The second is from VAZ 2113 to VAZ 2115.

Depending on the type of car (sedan or hatchback), a certain type of muffler is installed. So, in the VAZ 2114 under consideration, there is a muffler on the hatchback, which can be of an old or new model.

The newer models lack the curved tube that may have made the older models more material-intensive and expensive to manufacture. In the absence of a curved tube, the operation of the system has not changed.

Many car enthusiasts, wanting to save on mufflers, purchase first-generation models to install them on the VAZ 2114. As for the mounts, they are really identical, but when buying a cheaper first-generation model for installation on the VAZ 2114, you will have to bend the tail of the exhaust pipe. Many also do the opposite, purchasing mufflers from the VAZ 2114 for installation on older models.

Replacement of components

To change the muffler, you will need:

• ring wrenches for 13;
• new muffler;
• grinder or hacksaw (when dismantling old, too firmly attached or corroded parts).

Replacing the muffler VAZ 2114 is as follows:

1. Drive the car into the viewing hole. Wait for the exhaust system to cool down after driving.
2. Using 13 wrenches, unscrew the bolts on the clamp, with which the inlet pipe of the main muffler is connected to the outlet pipe of the additional one. Remove the screed clamp and all fasteners, having previously covered them with engine oil or brake fluid for ease of operation. If the fasteners do not loosen (for example, due to corrosion), use grinder. It will help cut off corroded fasteners or a clamp.
3. Remove the main muffler. To do this, remove the rubber suspensions from the brackets holding them on the car body.
4. Pull the muffler completely out from under the car.

The part is installed in the reverse order.

Silencer VAZ 2114 is in the area of ​​increased attention. Unlike many, even earlier VAZ models, the reincarnation of the "nine" in the image of "2114" has a silencer that is quite simple in design.

Replacing the muffler VAZ 2114 - nothing has changed

The leading domestic automaker is undisputed leader in the number of attempts to return to the assembly line car models that, it would seem, have become obsolete. Many VAZ cars are long-lived, holding on production line long decades. Each new update concerns not only the appearance, but also some design features.

Although the 2114 model is more attractive than its predecessors, the exhaust system has not changed dramatically. It is presented in the same curved steel pipe and a silencer in the form metal cylinder. There is nothing in itself that could protect him from the old problems.

In reality, the exhaust system is subject to serious damaging factors:

• heating to high temperature;
• frequent change temperature regime: from heating to rapid cooling;
• absence effective means metal protection;
• external and internal corrosion;
• blows and damage;
• pollution and exposure to abrasive particles from the roadway;
• constant vibration.

No wonder that muffler VAZ 2114, as well as on other cars, very quickly becomes unusable. As soon as the integrity of the system is broken, and the exhaust begins to go into the cracks and fistulas that have formed, it becomes impossible to drive. Exhaust pipe breakdowns can provoke not only the appearance, but also a change in the operating mode. Sometimes a repair can delay the need for a replacement, but that's only for a while.

We change the muffler VAZ 2114 - procedure

Before proceeding with the replacement of the muffler, it is necessary to perform a number of preparatory steps. First of all, you should visit the store and get a new set of exhaust system. Among a large assortment you can choose standard mufflers, that is, exactly the same as installed at the factory or. To the choice of fashionable and beautiful exhaust pipes, which, in addition to being attractive, appearance, have high cost, should be handled with great care.

The muffler is not without reason has such a design. In addition to making the exhaust sound quieter, its task is to create a balance in the gas distribution system. The use of any mufflers that differ in design will inevitably lead to the need to re-regulate the power system. At the next stage of preparation, it is necessary to install the car on a flyover or inspection hole and soak the bolted connections of the compression coupling with a special WD type fluid, brake fluid or engine oil. Threaded connections are heavily coked, the parts stick to each other, and it will not be so easy to remove them. In addition, a set of ordinary wrenches, spare rubber bands (pillows) for hanging the muffler to the bottom should be at hand.

Replacing the silencer VAZ 2114 is theoretically very simple:

• the bolted connection of the compression coupling is unscrewed;
• the coupling and sealing ring are removed;
• the silencer is removed from the rubber pads and removed.

The muffler is installed in the reverse order.

"Surprises" for the driver - you need to be prepared for them

A very simple technical method of attaching a muffler is not at all a reason to consider the work of replacing it easy. The ferrule bolts often stick so hard that soaking and using wrenches with extension arms may not always help.

In this case, muffler replacement VAZ 2114 should be made using more radical way dismantling. Old bolts on the coupling can be cut off with a hacksaw or disc grinder. These parts can no longer be reused, so they can be safely removed mechanically.
