Main components, operation and repair of the VAZ 2110 exhaust system

The exhaust system of the VAZ-2110 is designed for cleaning exhaust gases. The components included in it have a fairly long service life. But since the entire system is constantly experiencing temperature overloads, the metal gets tired, cracks and burnouts appear. Repairing the exhaust system yourself is quite simple. This allows owners of the “ten” to significantly save on maintenance. The design of the exhaust system includes: the main muffler, neutralizer, exhaust pipe and resonator.

Typical exhaust system faults

Be sure to verify that there are any problems with the exhaust system before starting any repairs. And identify the node that has become unusable. Any breakdown reveals itself with the following signs:

1. Broken connecting pipes. As a result, the integrity of the entire system is compromised and exhaust gases are not properly purified.
2. Burnouts on the elements of the main muffler and resonator. This leads to the fact that the exhaust gases are not cleaned, and an extraneous sound appears when the engine is running.
3. Strong noises appear from the exhaust system and the main muffler, indicating that there is damage.

If small cracks appear in the VAZ-2110 exhaust system (8-valve injector), then in the early stages they can be healed using sealants. This measure will increase the service life of the elements slightly, by no more than one year.

How to remove the main muffler on a ten

As with most front-wheel drive models, replacing the exhaust system of the VAZ-2110 is quite simple. You do not need any special skills, extensive experience, or special tools.

But it is advisable to carry out all work on an inspection hole or overpass. The sequence of work is as follows:

1. The connection between the resonator and the muffler is made using flared pipes and an O-ring. This connection is crimped with a metal clamp, which consists of two halves and bolts.
2. First of all, dismantle the clamp; to do this, unscrew the nuts from the bolts using two 13mm wrenches and remove the O-ring. On cars of the tenth family, sealing rings made of graphite are used. Therefore, they do not stick to the surface of the pipe.
3. Remove the old main muffler from the rubber hangers.

Composition of the output unit

The exhaust system for a VAZ 2110 car consists of the following elements:

• Exhaust manifold;
• Lambda probe;
• Receiving type pipes;
• Neutralizer;
• Two mufflers: main type and additional.

Not all exhaust components are disassembled; some parts, such as the converter, as well as both mufflers, are replaced entirely.

Installing a new muffler

Assess the condition of the rubber hangers, which are located on different sides of the main muffler body. If they are overstretched or have cracks, be sure to replace them with new ones during installation.

The cost of these rubber bands is small, they are available in any store. Next you need to do the following:

1. Install the new main muffler onto the rubber hangers.
2. Insert a graphite O-ring between the pipe flares.
3. Place the clamp in place and tighten the nuts using 13mm wrenches.

At this point, the repair of the main muffler of the VAZ-2110 exhaust system (8 valves) is completed. Start the engine and check the muffler operation. There should be virtually no sound from the exhaust pipe. The motor will run clean and smooth.

Why is it needed and why is it installed?

If you take everything apart, you get this information.

1) Lightening allows the engine to operate at higher speeds, this is useful for tuning engines, for example with a compressor. And as you know, at high speeds, power increases.

2) The engine picks up speed faster, it does not need to waste energy spinning heavy pistons.

3) The engine runs more smoothly and detonation is reduced. Watch a short but informative video.

4) There is an opinion that the service life of parts is increasing. Since the loads experienced are reduced due to a decrease in the weight of the piston.

If we sum up the intermediate result, it turns out - faster (higher revs), more confident start from a standstill, less detonation, longer service life.

How to remove the resonator

The resonator needs to be changed only after a new muffler has been installed. The sequence of work aimed at dismantling the device:

1. The resonator is secured using a crimp-type clamp and an O-ring.
2. The connection to the neutralizer is made using a floating flange, which consists of flared pipes and two bolts.
3. The fist is located on the opposite side of the resonator.

The work must be carried out on a cooled engine.

Quite often it is not possible to unscrew the bolts, so to make the work easier, you just need to cut them off using a grinder. Be sure to install new bolts during reassembly. If you don’t have a grinder at hand, then you need to use a penetrating lubricant, for example, WD-40. Apply this composition to all threaded connections, then wait 20-30 minutes.

Unscrew all the bolts and remove the clamps on the resonator. After this, you need to remove the old resonator from the rubber suspensions. Be sure to evaluate the condition of all rubber products. If they show signs of wear, install new ones during reassembly.

Resonator installation

In the VAZ-2110 exhaust system (16-valve injector), work is performed in exactly the same way as on 8-valve engines. The procedure is as follows:

1. The new resonator must be mounted on rubber hangers and connected to the muffler. Moreover, it is necessary that the pipe from the resonator be strictly parallel to the ground.
2. If the neutralizer has wear, rust, or burrs, the connection must be lubricated with high-temperature sealant. This will ensure a high-quality connection of the exhaust system components.
3. Tighten the resonator and catalytic converter flanges using only new nuts and bolts.
4. The resonator is fastened to the neutralizer using two bolts and flanges. Moreover, the pipe is secured to the pants using a spring connection and flaring. An O-ring made of metal asbestos or graphite is installed inside.

This completes the replacement of the resonator; repairs present no difficulties. All work can be done independently, you just need an inspection hole or overpass.

How to remove the neutralizer

The VAZ-2110 exhaust system is standard for all cars. Almost the same design is used on nines, sevens, and even foreign cars. Even a motorist with very little experience can repair all elements of the system. If you have already decided to change the resonator and muffler, then it is also advisable to install a new neutralizer. The neutralizer is necessary to dampen the vibration coming from the car engine. This is a device that mechanically separates the muffler resonator and the exhaust pipe.

Replacement is carried out as follows:

1. If there is no damage to the springs and bolts, they can be reused. If there is wear, you need to purchase new elements.
2. The ring is replaced in any case, even if it is in almost perfect condition. If this ring begins to allow exhaust gases to pass through, damage to the flaring of the exhaust pipe and the converter will occur.
3. Unscrew all the bolts used to secure it. They must first be treated with a penetrating lubricant.

Sound absorption technologies

The exhaust system, and in particular the muffler, can use one or several sound absorption technologies:

• change in gas flow cross section;
• changing the direction of gas movement;
• surface absorption of sound waves.

Depending on which frequencies predominate in the engine exhaust sound spectrum, this sound reduction method is used. For example, to suppress low frequencies, it is effective to use several resonator chambers with different volumes. The use of different sections of input and output pipes combats high frequencies well. But in principle, a muffler, like a good musical instrument, is customized exclusively for a specific brand of engine. Then the noise reduction efficiency is much higher and there is less power loss.

Installation of a new neutralizer

If you decide to modify your car, you can install the Stinger exhaust system on the VAZ-2110. It is more reliable and advanced than stock.

All work is carried out the same way. The neutralizer is installed as follows:

1. Install the neutralizer, and then put on the bolts. This must be done very carefully, making half a turn, no more.
2. When tightening, you must first tighten the bolts that secure the neutralizer to the resonator. The last to be tightened are the bolts securing the converter to the exhaust pipe.

Replacing plugs for VAZ 2110

Car owners often encounter the problem of fluid leaking from the cooling system. Often the reason lies in rusted or squeezed out plugs in the engine cylinder block. To fix the problem, just replace them with new ones.

Plug locations

So:

• There are plugs on the sides and ends of the cylinder block that are squeezed out of the block when the coolant freezes in it.
• Two plugs with a diameter of 34 mm are located on the cylinder block on the side of the coolant drain plug, and two more on the oil filter side
• There is another plug with a diameter of 17 millimeters on the rear end side of the crankcase
• The last plug with a diameter of 34 mm is located at the front end of the cylinder block

These plugs are changed if the coolant in the cylinder block is frozen. The plugs can be changed without removing the engine. On a VAZ 2110, replacing the cylinder block plugs is done using a special tool. To do this you will need:

• beard or chisel
• hammer
• pliers
• durable screwdriver
• telescopic magnetic pointer (purchased at any automotive store)
• new plug
• sealant
• skin

Replacing plugs for a VAZ 2110 engine block

• Remove the negative terminal from the battery
• Drain the antifreeze from the cylinder block and radiator
• Remove the air filter along with the hose
• We disconnect the exhaust pipe together with the bracket and lower it down a little so that the flange is removed from the manifold studs
• Turn the movable sector of the throttle valve drive all the way and disconnect the throttle valve drive rod
• We unscrew the bolts securing the throttle valve drive bracket. We move the bracket without disconnecting the rod to the side so that it does not interfere with us.
• Remove the belt protective cover and cylinder head cover
• We unscrew the nut securing the tension roller and remove the roller along with the axle and a special spacer ring, then remove the timing belt from the camshaft roller
• We unscrew the bolt securing the pulley and remove the pulley along with the key.
• Unscrew the nut securing the timing belt to the block head itself
• If necessary, unscrew the bolts securing the head and remove the block head.

Now that we have access to the plugs, we begin replacing the plug of the VAZ 2110 engine block.

• We take a beard or chisel in one hand, and a hammer in the other
• Place the chisel on the edge of the plug
• Gently tap the hammer on the striking part of the chisel. The plug turns (Photo below)

We tap with a hammer on the striking part of the chisel, the plug rotates

• We pry it up and pull it out using pliers
• If the plug does not turn, drill a small hole in it, screw a knob into it and remove the plug.
• We use a telescopic pointer with a magnet if it is necessary to remove a plug that has fallen inside. We pull the failed plug to its hole and remove it with pliers
• Clean the edges of the plug hole from rust using sandpaper
• To increase the tightness, coat the edges of the installed plug with sealant
• Attach the plug to the hole
• We press it in using a suitable mandrel and a hammer.

Press in the plug using a mandrel and a hammer

• Reinstalling the block head
• Fill the cooling system with antifreeze (antifreeze) or water
• Connect the negative terminal to the battery.
• Checking the engine operation

Removing the exhaust pipe

Most drivers call the exhaust pipe “pants”, since the element is very similar to this item of clothing. It is secured to the exhaust manifold using bronze nuts and studs. The trousers are attached to the neutralizer using a spring-loaded connection. There is a gasket between the exhaust manifold and the pants to prevent gases from leaking.

Dismantling the intake pipe is carried out as follows:

1. Using a 13mm wrench, you need to unscrew the nuts that secure it to the exhaust manifold. If there are metal plates with bent edges under the nuts, they must be bent. Please note that the connection uses studs that are screwed directly into the manifold.
2. If the stud is damaged, replacement is quite problematic. Therefore, it is necessary to carry out all work carefully to keep the threaded connection intact.
3. Be sure to allow the engine to cool before starting work, then apply penetrating lubricant to all threaded connections. With these simple steps, you won't have to use too much force, which will save your studs. If you break a pin, it will need to be drilled out. Before this, the exhaust manifold must be removed. Moreover, if you damage the exhaust manifold, replacing it will cost you a pretty penny. The cost of a new one is more than 2000 rubles.
4. After unscrewing all the nuts, it is necessary to move the exhaust pipe to the side and remove the gasket.
5. Unscrew the bolts that connect the exhaust pipe to the converter.

This completes the dismantling of the exhaust pipe of the VAZ-2110 exhaust system.

Description of individual components

To make the structure of such an element as the discharge system clearer, it is necessary to give a detailed description of all components:

• Neutralizer. A unit designed for effective purification and suppression of emissions of harmful substances into the environment. When driving, a car produces substances such as non-combustible hydrocarbons, oxide compounds of nitrogen and carbon. The work of this system is aimed at eliminating them. The design itself is a combination of two ceramic-type components. The surface of these components is coated with special afterburning catalysts, which include rhodium, palladium and platinum. These substances make it possible to purify exhaust gases emitted into the environment by almost 100%;
• Lambda probe. It is a special sensor whose task is to control the composition and amount of fuel that enters the engine. The lambda probe thereby controls the purifier. If the lambda probe does not work properly, then the entire output assembly will quickly become unusable, after which it will have to be replaced;
• Reception pipe. Designed for forced removal of exhaust gases from the cylinders of a power unit. The pipe is made of stainless steel, and its fastening to the collector is carried out using special pins, of which there are four in total. The studs guarantee reliable fastening of the two outlet pipes and the element. In order to combine the exhaust pipe and the neutralizer, as well as an additional muffler, hinged fasteners are used;
• An exhaust manifold. A component that is cast from pure cast iron. The manifold is secured with four studs in the exhaust pipe. Heat-resistant gaskets reinforced with metal are installed between the manifold and cylinder heads.
• Silencers. Necessary for effectively suppressing the exhaust rate of burnt gases. This is necessary in order to significantly reduce the noise level in a type of transport such as the VAZ 2110. The distribution device in this part of the unit is carried out as follows: the additional one is followed by the main one. These two components are connected to each other by clamps and sealing rings and are covered with a special casing on top.

Replacing a muffler on a VAZ 2108/2109 has its own nuances, which can be found here: https://vazweb.ru/desyatka/vyhlop/zamena-glushitelya-vaz-2109.html

Installing a new exhaust pipe

All work is done in reverse order. But there are several features that you definitely need to know:

1. Install a new exhaust pipe.
2. A new gasket needs to be installed between the exhaust manifold and the pants.
3. Be sure to install a new O-ring between the neutralizer and the pants.
4. Tighten the nuts on the exhaust manifold studs. Tighten them evenly in a crisscross pattern.
5. Tighten the bolts that are on the spring-loaded connection to the converter.

This completes the repair of the exhaust system. The sound will be muffled as much as possible, the car will become almost silent. It is advisable to lubricate the new gasket with a CV joint type compound. This will improve the seal.
