Preparing to replace exhaust system elements

The part of the muffler that changes

After a certain time, each owner of a VAZ car will have to change one of the elements of the exhaust system, or maybe even several. The cost of replacing one part is quite reasonable, but you can save money here too by doing the work yourself. To carry out work to replace the exhaust system or its parts, you do not necessarily need any special tools.

To perform this repair you will need:

• lubricant WD-40 or its equivalent, such as a variety of liquid keys needed to soften rust;
• 13mm wrenches (one of them is a socket, the second is a head with a knob);
• hammer (if necessary).

Basically, exhaust system components begin to require replacement due to corrosion. A characteristic feature is the occurrence of unnecessary and unusual noise when the engine is running. You should know that when changing individual components of the gas exhaust system, the connecting clamps oxidize and become corroded, so their fastenings and they themselves become unsuitable for use.

Rubber pads for suspension of the resonator must undergo a processing process during disassembly. To avoid problems, it is recommended that when changing individual components, you immediately stock up on clamps for installation and connection processes and rubber pads for suspension.

Description of the design of the exhaust gas system Lada Kalina 1117 2004 - 2013

Exhaust system:

1 — heat shield; 2 - sealing gasket; 3 — catalytic collector; 4 — oxygen concentration sensor; 5 — metal compensator; 6 — rubber cushions; 7 — additional muffler; 8 — main muffler; 9 - sealing ring; 10 - clamp.

The exhaust system consists of an exhaust manifold, integral with the catalytic converter (catcollector), additional and main mufflers and pipes connecting them.

Catcollector with oxygen concentration sensor

A sensor for oxygen concentration in the exhaust gases (lambda probe) is installed in the upper part of the catalytic collector (before the converter). On cars that comply with Euro-3 standards for the concentration of harmful substances, two oxygen concentration sensors are used: the second - diagnostic - is installed after the neutralizer in the lower part of the catalytic converter. The exhaust gas catalytic converter is designed to reduce emissions of carbon monoxide, nitrogen oxides and unburned hydrocarbons into the atmosphere.

The car is equipped with a neutralizer with a metal carrier. It consists of many honeycombs made of corrugated foil and coated with afterburning catalysts. Passing through the honeycomb of the neutralizer, carbon monoxide is converted into low-toxic carbon dioxide, and nitrogen oxides are reduced to harmless nitrogen. The degree of gas purification in a working neutralizer reaches 90-95%.

For normal operation of the converter, the composition of the exhaust gases (in particular, the oxygen content in them) must be within strictly specified limits. This function is performed by the electronic engine control unit - a controller that determines the amount of fuel supplied depending on the readings of the oxygen concentration sensor.

If there are lead compounds in the exhaust gases, the catalytic converter and oxygen concentration sensor quickly fail. Therefore, operating a car on leaded gasoline is strictly prohibited, even for a short time.

A faulty ignition system can also cause the neutralizer to fail. If sparking is missed, unburned fuel enters the converter, burns out and cokes the cells, which can lead to complete blockage of the exhaust system and engine shutdown (or severe loss of power).

The controller has the function of protecting the converter from misfires, which can be detected in one or two cylinders at the same time. In this case, the controller turns off the fuel supply to these cylinders, and the engine management system malfunction indicator located in the instrument cluster lights up in a flashing mode. In this case, it is necessary to stop driving, stop the engine, try to find the cause and eliminate the malfunction. If this cannot be done, you will need to have the vehicle towed to the nearest service station.

Mufflers and catalytic collector are non-separable units; when they fail, they must be replaced with new ones. A metal-reinforced heat-resistant gasket (common for the catalytic collector and intake pipe) is installed between the catalytic collector and the cylinder head.

An additional muffler pipe is attached to the catenary collector on three studs. The connection is sealed with a heat-resistant gasket. A metal compensator is built into the additional muffler pipe. It reduces the transmission of power unit vibrations to the exhaust system.

The rear part of the additional muffler pipe is hingedly connected to the main muffler pipe. Between their flanges there is a metal ring with a spherical outer surface. The inner surface of the flanges is also spherical, the flanges themselves are tightened with a clamp.

Heat-protective covers are installed on the body, above the additional muffler and metal compensator. The exhaust system is suspended from the body on four rubber cushions.

Maintenance of the exhaust system consists of periodically inspecting it, checking for tightness of connections and the presence of through corrosion, and involves tightening loose connections.

Recommendations for replacing the resonator and muffler

Dismantling the old part

1. Unscrew the nuts securing the clamp connecting the muffler pipe and the resonator pipe. Remove the clamp. Lubricate the bolts and nuts with WD. Since they are completely stuck, it can be impossible to disconnect them. About 10 minutes after lubrication, you can begin to unscrew them. If it is impossible to twist the bolts, you can cut them off using a grinder (grinder). After this, the clamp is bent. Now, by lightly tapping on the bend of the muffler, you need to dislodge the clamp from its connection to the resonator. There is a possibility that the clamp can be easily removed without using a hammer.
2. Release the muffler from the fasteners, i.e., remove it from the rubber bands. There are two of them on the Lada Kalina. The first is somewhere near the rear beam, and the second is directly near the exhaust pipe itself.
3. Remove the muffler itself.

The resonator on Kalina is screwed with three steel nuts directly to the catalyst. Since the nuts also stick very well, they must be lubricated with a rust softener. If this method does not work, a grinder can help. When replacing the resonator with a new one, all steps are carried out in the reverse order. The following method of replacing the resonator is also used. The old unit is cut off from the corrugation to the main muffler, the new resonator is welded. The cost of the resonator and muffler ranges from 1000 to 4000 thousand rubles.

Despite the huge selection of resonators from various companies and manufacturers, it is very difficult to find a worthwhile one. Since the resonator of the Lada Kalina is corrugated, it is advisable to find the same one made of stainless steel. However, there are practically no such offers on the Internet. You can install something else, the car will be able to work quietly, which will delight any car owner.

To learn in detail how to independently replace the resonator or the entire exhaust system on a Kalina, you can use information on the operation and repair of the Lada Kalina on online forums, video tutorials and photo reports.

According to experts, the car resonator must be replaced every 20 thousand kilometers. Any driver who has driven that many kilometers will be able to detect malfunctions of the device, usually by ear. It is recommended not to purchase cheap fakes. Practice proves that in this case, approximately 700-1000 km after changing the air resonator, you can return to the service station again.

Both the owner of a new car and the buyer who purchased a used car can face the problem of replacing the resonator on Kalina. Based on the foregoing, you can carry out repair work and replace parts of the exhaust system yourself or by contacting a car service center. Replacing the resonator is inexpensive. It should be remembered that without timely replacement of one of the components or if it is completely absent from the exhaust system, the remaining parts may burn out. And then repair work will cost more.

Reasons for replacing the catalyst on a Kalina car with an 8-valve engine

Many Kalina car owners are confident that even a serviceable catalyst to a certain extent prevents the engine from developing its potentially high power. This judgment is wrong. If it comes to clogged or melted honeycombs in the catalyst, then this state of this device can directly limit the power developed by the engine.

Premature failure of the catalyst in a Kalina car is a consequence of a group of the most common factors associated with careless treatment of the car and its operation with a obviously faulty fuel supply and ignition system. The main reasons for device failure:

Changing the muffler with your own hands

Lada Kalina Hatchback MyLittleFriend Kalinich Logbook Floating speed or Replacing the idle air control

Work to replace the Kalina-2-Universal muffler will require the preparation of the following tools and consumables:

• key to 13;
• WD-40 lubricant;
• hammer;
• flat screwdriver;
• new part (muffler).

The most difficult and time-consuming stage of this work is considered to be the dismantling of the device. If you can't remove the part with a hammer, use a screwdriver. Find the clamp that connects the resonator to the muffler. It should also be dismantled, but this will be difficult to do: the bolts stick over time and are very difficult to unscrew. They need to be lubricated with WD-40 and wait 10-15 minutes. Only then should you try to unscrew the bolts again. Experts advise using long wrenches, because in some places it will be very difficult to unscrew the nuts.

After you have removed the clamp, remove the muffler from the rubber hangers. There are only two of them: the first is located near the very bottom of the car, and the second is located near the edge of the muffler. After this, the device can be removed.

To install a new muffler, you should do all the steps described above in reverse order. Change pillows if necessary. You need to be sure that the parts that make up the exhaust system do not come into contact with body elements even during minor vibrations. Otherwise, a constant knocking noise will be heard while driving. Before attaching the muffler, it is better to remove all stickers and price tags from it. At the end of the work, you can put a special chrome attachment on the Kalina-Universal muffler as a tuning option.

The result of the work

In order for the muffler to last a couple of thousand km longer, before installation it is necessary to fill it with a special liquid that prevents corrosion from forming. The muffler must be twisted in different directions so that the liquid completely lubricates the internal space.

As a result of replacing the muffler, the sound of a running engine will not frighten passers-by, alarm drivers or infuriate traffic police inspectors. And comfort.

During operation, the engine produces certain noises, which require the installation of appropriate equipment to suppress them. The muffler for Kalina is represented by a tube, which includes the muffler itself and the resonator.

Its body is solid and sealed, it is made without welding, which indicates good protection against rust. After some period of use, the device wears out and begins to work louder. As a rule, drivers of a Lada sedan, station wagon or hatchback, whose mileage is at least 40 thousand kilometers, encounter this problem. If the part is worn out, it can be “patched”, but its complete replacement is recommended. You can do this yourself using a hammer, wrenches and lubricant.

How to determine if the Lada-Kalina muffler is faulty

To find a faulty exhaust system, you don’t have to be a car mechanic or have extensive experience in car repairs. To identify problems, you need to act in the following sequence:

Pay attention to noises that are made while driving. If the muffler is faulty, the sound will be quite loud. Extraneous noises also indicate problems with the exhaust system. Raise the car with a jack or drive onto an overpass and inspect the system body. A working device should have no holes or rust. The presence of traces of corrosion indicates that, most likely, there is a problem with the housing. While driving, you need to monitor the color of the exhaust: the periodic appearance of black and dense smoke will indicate that there are problems with the exhaust system. Start the engine and press the gas pedal for several minutes. Then turn off the ignition and check the engine temperature. During this time it should not get very hot. If it has risen significantly, it means that there are problems in the performance of the mechanism.

Quite often, the muffler body is exposed to corrosion, which leads to the appearance of holes and, as a result, a loud exhaust sound.

Malfunctions of various types can occur with the exhaust system, but the most common is unreliable installation of muffler elements. As a result of poor-quality connection, the unit quickly fails. In addition, common malfunctions include:

• loss of tightness as a result of burning out of individual elements (corrugations, gaskets);
• catalyst problems;
• mechanical damage;
• exposure to corrosion, which leads to the appearance of holes.

One of the malfunctions of the Lada-Kalina exhaust system is burnout of the corrugation

Main reasons for failure

The muffler corrugation is subject to breakdowns more often than other parts of the exhaust system. Often the corrugation is damaged as a result of mechanical stress. This could be impacts on any hard objects: stones, hummocks, objects protruding relative to the roadway, etc.

The cause of the malfunction may be the unsatisfactory technical condition of the transmission. If the engine shock-absorbing mounts are worn out, then due to insufficient fixation of the power unit, a large tensile force acts on the corrugation. In some cases, damage to the corrugation may be caused by improper installation or dismantling of the muffler.

Don't forget about the catalyst. If it is clogged, exhaust gases will begin to accumulate, causing a critical level of pressure to be created in the system. It’s not for nothing that it was mentioned above that the corrugation resembles a fuse.

Ultimately, it is she who cannot stand it (electricians will understand), gases break through and often reach the cabin. And this, in turn, negatively affects the health of the driver and passengers.

If the corrugation braid is damaged, it cannot be repaired due to the complexity of the design. By and large, this is a disposable part and if the winding is broken, then the entire part needs to be replaced.

Since corrugation plays an important role in the exhaust system of every car, it must be made from high-quality raw materials. Typically high alloy stainless steel is used for this.

Resonator structure and functions

This is the part of the muffler

The resonator device on Kalina is a structure, each link of which performs its own function. Air flows of gases settle on reflectors - the most important components that make up the air filter resonator. Gases evaporate due to the interaction of two flows passing through the cavities of the exhaust resonator. The intake and exhaust resonators perform the same function: they move gas through the exhaust system.

The serviceability of a car resonator affects the durability of all engine components. Each element of the exhaust system is exposed to an aggressive environment and high temperatures, and the muffler resonator is no exception. The performance of the exhaust system resonator is determined by the condition of the catalyst, the cleanliness of the muffler and the diameter of the pipes.

The muffler resonator on Kalina is produced in two types: for two-stroke and four-stroke engines. Experts note that for 4-cycle engines the air resonator is a hindrance and in its absence the engine power can be increased by about 15%. In turn, a car or, more often, motorcycle resonator performs the most important task in a two-stroke engine, because in its absence, not only exhaust gases, but also unburned fuel will begin to splash out of the engine. This will lead to a decrease in speed power and an increase in fuel consumption while driving.

Compared to systems on other cars, the resonator on Kalina has a corrugation. This is due to the greatest mobility of the structure, that is, in this case it directly depends on the standard connection through the ring. But it will no longer be enough. All components of the resonator and muffler must be made of high quality stainless steel.

Correct selection

In order for the muffler corrugation to reliably protect the exhaust system of the car, and at the same time the body, you need to know some of its features. This will help you choose the best option without overpaying.

Before you go to the auto parts store, you need to determine the type of old element. It is usually located in two positions:

In a horizontal position, the corrugation can be seen, if viewed from the side of the power unit, then after the first bend of the exhaust pipe. In this case, it bends under load. As for the length, it can reach up to 400 mm with a diameter of 65 mm. When choosing a new part, you need to focus on the dimensions of the old one.

In a vertical position, the corrugation, under the influence of the load from engine operation, first compresses and then straightens. Typically, such elements have a reinforced design. At the same time, the dimensions are limited: the length is no more than 150 mm, and the internal diameter is 65 mm. When choosing this part, it is important to consider how the old corrugation is welded.

Video - replacing the muffler corrugation on an Opel Zafira:

Any type of elastic element is placed on the exhaust system pipe using the overlap method. The main thing is to take into account the following nuance: if it is not possible to remove the welds, excluding damage to the exhaust system pipe, you should choose a corrugation of the same length as the old part. If they can be cut, then the corrugation needs to be selected 20 or 30 mm longer.

In addition to the two main criteria for choosing a corrugation (length, internal diameter), it is also important to take into account its quality, which always depends on the manufacturer. Common brands in the automotive market are the German company Ehler and the Italian manufacturer Hydra. The cost of parts can vary from 800 to 1500 rubles. There are cheaper options, but if you want to save money, you should remember that it is not always justified.

Exhaust system of Lada-Kalina

Owners of a Lada-Kalina car sooner or later have to deal with the repair or replacement of a muffler. This unit is one of the problematic ones, which is associated with factory defects. Despite the fact that the design is made in the form of a solid and sealed body without welds, after a run of 40 thousand km the system wears out: the integrity of the body is compromised, the sound becomes louder. The muffler can be repaired by installing a patch on the burnt area using welding. However, such a measure will only temporarily eliminate the problem. Therefore, it is recommended to replace the element with a new one. The exhaust system is designed in such a way that even an inexperienced motorist can diagnose and replace it with his own hands.

The part differs depending on the modification of the car. Thus, for sedan and station wagon bodies a model with a curved pipe is used, and for a hatchback - with straight inlet and outlet pipes. The part numbers are as follows:

• 1118–1200010 main muffler for Lada-Kalina sedan and station wagon;
• 1119–1200010 main muffler for Lada-Kalina hatchback.

What does the Lada-Kalina muffler consist of?

The main purpose of the exhaust system is to absorb noise from engine exhaust gases. On the Lada Kalina, the unit consists of a resonator and a muffler. The parts are connected to each other with a clamp and an o-ring. The muffler is a one-piece structure, and the resonator consists of several closed chambers. The chambers are connected by small tubes with holes. This design ensures smoothing of sound vibrations by the resonator. In the latest versions of the car, the joints are additionally laid with noise-absorbing material.

Replacing a part at a service center

When replacing a muffler, you need to be especially careful, since there are many types of the device depending on the car model. The desired option is selected in accordance with the dimensions and mounting locations. If problems arise during independent work or you are not confident enough in your actions, it is better to replace the device at a service center. To do this, you will need to prepare a certain amount of money.

Replacing the muffler is a simple operation. Its price should be appropriate - no more than 1500-2000 rubles (excluding the cost of the device itself). If the cost exceeds this threshold, it may be a scam. But if they ask for 200 rubles for the work, you shouldn’t expect high-quality repairs.

The resonator may need to be replaced. The resonator is the second important part of the muffler. It performs the same functions as the main muffler, but additionally protects the device from sparks and flames. In case of malfunctions, it must be urgently replaced.

Replacing the Lada Kalina resonator is done in exactly the same way as replacing the muffler. If problems occur, it is better to contact the service center.
