Replacing the exhaust pipe of a VAZ 2114

You've probably heard such a slang and quite common word among car enthusiasts as VAZ 2114 pants. If you have no idea what it is, then everything is simple, it's just the exhaust pipe of the exhaust manifold.

The product is used to remove exhaust gases directly from the internal combustion engine. And it got its original name for the shape of the structure (one end of the pipe has a split and closer to the opposite edge smoothly flows into a single pipe) with the shape of the pants. This is how the popular name “clung” to the product.

From a design and reliability point of view, the most vulnerable point in the exhaust pipe is the sealing gasket at its connection to the manifold. Over time, the insulating element simply burns out or becomes deformed from exposure to high temperatures, especially since the thickness of the gasket metal is quite small.

Removing and installing the catalyst

Removing and installing a catalytic converter on a VAZ 2115 is a relatively simple task. The procedure itself is carried out in several stages:

1. Using keys “17”, unscrew the fastening of the catalyst to the exhaust pipe of the exhaust manifold. We take out the bolts and spring washers;

2. Place a suitable stand under the catalyst. The fact is that the catalyst on the VAZ 2115 car is not fixed with the help of any rubber hangers, and therefore, in order for it not to fall on your head, after unscrewing the fastening bolts, it must be secured somehow. This can be done either by installing a stand under it, or by temporarily securing it with wire;

3. Now unscrew the catalyst from the inlet pipe of the additional muffler and carefully remove it.

We install the new catalyst in the reverse order.

How to replace a muffler on a VAZ 2114/2115

If you start having any problems with the muffler, it is better not to put it off for a long time. The life and health of the driver and passengers depends on how correctly the “glushak” works. In general, the replacement process itself begins with the selection of a new exhaust system kit. It is best not to save money, but to purchase an original factory one. This will delay the need for repeated replacement indefinitely.

In addition, it is recommended to change the fastening bolts during each replacement. It is necessary to choose products made from heat-resistant materials, since otherwise the bolts will quickly stick to the bottom and will be impossible to unscrew.

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

What tools will you need?

To work you will 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 an overpass or inspection 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 regular jack.

To remove the “glushak” from a VAZ 2114/2115, you must:

Jack up the rear left edge of the vehicle.

Make sure the machine is stable.

Reach under the body and moisten all pipe connections and bolts with lubricant.

Wait 10–15 minutes until the liquid is absorbed.

After which you can begin to unscrew the bolted connections. If the bolts cannot be unscrewed with regular wrenches, it is recommended to cut them off with a chisel and hammer. However, you need to act extremely carefully so as not to catch the bottom.

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

The dismantled muffler is pulled out from under the car.

How to install a new one and secure it correctly

Before you begin installing a new muffler, you need to clean all strategically important places under the bottom: hooks for attaching rubber bands, brackets for bolts. Install the product in the reverse order:

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

After this, hang the exhaust pipe and resonator on rubber hangers. Make sure that each connection is secure and the part will not fall off the hooks at the first road pothole.

Next, start tightening the nuts on the bolts. Screw it all the way, but without fanaticism, as you can break the thread.

Lower the car from the jack.

After this, it is recommended to check the performance of the VAZ. It will be enough to start the engine and rev it up a little.

What is this?

Engine overhaul refers to the work of a master aimed at returning the engine to a state as close as possible to its original state. In this case, most of the nodes are changed or restored. This type of repair is resorted to when there is a lot of wear on the parts of the unit.

The list of work may include grinding the crankshaft journal and camshaft, installing new pistons and springs, and honing the cylinders. If too many engine components are faulty, then it is more advisable to completely replace it.

The following signs indicate that it is time to overhaul the engine on the VAZ-2114:

The appearance of red, black or dark gray carbon deposits on the spark plugs.
Increased oil consumption.
The occurrence of knocking in the engine.
Increased fuel consumption.
The appearance of smoky exhaust.
Bad traction.
Engine overheating.
At idle, the engine runs unevenly.
Reduced power.

Major repairs proceed approximately according to this scheme:

Preparing the engine for dismantling (disconnecting wires, hoses, gearbox).
Removing the engine.
Removal and inspection of the cylinder head.
Disassembling the unit for diagnostics and cleaning.
Block boring. Grinding the crankshaft. Application of hone to the cylinder walls.
Weight distribution of connecting rods, pistons.
Block assembly.
Restoring the head (replacing caps and guides, straightening seats).
Assembling the engine and installing it in the engine compartment.
Connection.
Functionality check.

What is a car muffler for?

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

The muffler is an integral part of the exhaust system . Its main purpose is to remove exhaust gases outside the car. In addition, the part also serves to reduce noise, since residual fuel can burn in the exhaust system pipes.

How to attach

The muffler on the VAZ 2114/2115 is attached to the car body. To ensure that the pipe is securely fixed and does not vibrate during movement, two fastening methods are used:

bolted;
on rubber suspensions.

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

The muffler is attached directly to the exhaust manifold with bolted connections, which guarantee complete tightness of the joints. The middle part is also fixed with bolts and nuts. And the resonator and exhaust pipe are suspended on special hooks on the bottom with elastic bands. These suspensions are easy to remove and put on, but at the same time provide rigidity even when driving on uneven roads.

Schematic design of the exhaust system on a VAZ 2114/2115

The gas exhaust system of the VAZ 2114/2115 consists of several parts. Connecting to each other in series, all parts ultimately serve one purpose - reducing noise and removing exhaust emissions outside the body.

1 — bracket for fastening the exhaust pipe; 2 - gasket; 3 — clamping device for the bracket; 4 — additional muffler; 5.7 — “pillows” for muffler suspension; 6 — main muffler; 8 — clamp connecting the muffler pipes; 9 - neutralizing device; 10 — hinge sealing ring; 11 - sensor that monitors the oxygen concentration in emissions; 12 — exhaust pipe for mufflers

Symptoms of a problem

The main sign indicating possible problems with the gasket of the VAZ 2114 pants is a changed sound (bass) from the exhaust pipe when the engine is running. When an element wears out, you will immediately hear and identify disturbances in the operation of the exhaust system. This will increase the noise level and exhaust sound. However, it is worth understanding that such signs may indicate failure of other components of the exhaust system (for example, the resonator). To accurately determine the possible causes, conduct a thorough diagnosis.

Fault diagnosis

To determine operational problems, you should start the car engine. It is best to carry out the activities together, so that one person sits in the driver’s seat and, at the command of the second, increases the operating speed of the engine. The second person should be located in the inspection hole or under the overpass exactly under the bottom of the car. When the speed increases, you need to carefully inspect the entire exhaust system line, record the source of increased noise and possible leakage of exhaust gases. If you have decided to replace the problem unit, read below for instructions on how to change pants on a VAZ 2114.

Should high-voltage wires be replaced and when?

No matter how well the armored wires are made, they also have a limited service life. According to current regulations, they must be replaced after every 30,000 km traveled. In practice, many motorists ignore this rule, continuing to travel with wires that have already outlived their useful life.

Such inattention can cause a whole host of problems, including:

poor ignition;
overclocking problems;
engine tripping;
inability to start the car.

All these troubles are caused by one single factor - an increase in the electrical resistance of the core of high-voltage wires, as a result of which it becomes “more difficult” for the impulse from the coil to reach its destination.

You can check whether you can still drive with the old wires or not - at home.

To do this you need:

Turn off the ignition.
Remove one of the armored wires.
Measure its resistance using a megohmmeter or multimeter in the appropriate mode.
If the resistance turns out to be equal to or close to the figure indicated on the wire insulation, then it is in good condition, but if it turns out to be greater, then the wire should be replaced.
Repeat this operation on the remaining three wires.

It should be remembered that if only one of the wires is faulty, then all four should still be replaced.

Also, do not forget about the cleanliness of the contacts of high-voltage wires - they can also cause ignition problems. If oxides are noticeable on the metal tip, they should be cleaned with fine sandpaper or a cloth moistened with kerosene. By following these simple rules for caring for armored wires and replacing them, you can almost completely avoid troubles associated with the ignition system.

Silencer - purpose, device, operation

An important element of the exhaust system is the muffler; operating a car without it is impossible. As a rule, the muffler is located at the rear of the vehicle and, in conjunction with the exhaust system, serves to remove harmful gases from the engine, bypassing the vehicle interior.

Car mufflers are made from stainless, aluminized and regular black steel. Stainless steel “silencers” are practically not available for sale due to their high cost and long service life (their service life is 10–15 years). Aluminized mufflers are installed on VAZ 2114/2115. They are common in the domestic and European markets (service life 3–7 years). Regular black steel mufflers are cheap substitutes and last only a few months, so are rarely used.

What does the price depend on?

Motorists who need engine overhaul of a VAZ-2114 are faced with different prices for such a service. The cost depends on the influence of factors:

Engine capacity.
The prestige of the service company, its pricing policy.
Urgency.
Scope of work.
Difficulty of repair.
The need for a specialist to visit.
Cost of spare parts.
Equipment used.
Automotive technician qualification level.

The more work is required to restore the engine of a VAZ-2114 car, the more expensive the service of a specialist will cost. You will have to pay extra for urgency and a specialist visit.

Cylinder head gasket VAZ 2114: features

In fact, the cylinder head gasket is a seal, that is, an element consisting of several layers. The seal can be made of reinforced flat composite sealing gasket material (paronite) or from thin sheet material with metal edging of the holes for the combustion chambers.

As mentioned above, the gasket is installed in the place where the VAZ 2114 cylinder head and the VAZ 2114 cylinder block itself are connected. During operation, this gasket experiences loads (temperature and others) and wears out. Also, given that the walls of the holes in the gasket are quite thin, this can lead to its burnout, damage and deformation.

Causes of breakdowns of the VAZ2114 exhaust pipe

Since the unit is attached directly under the bottom of the car, and our Russian roads leave little to be desired, the most common occurrence is driving into a hole (even worse if it is hidden under a puddle) with subsequent damage to both the exhaust pipe itself and the place where it connects to the muffler. The second most common reason is the vulnerability of the gasket itself. The fact is that it is constantly exposed to a strong influence of hot exhaust gases, therefore, in an aggressive environment, the destruction of the product (burnout) accelerates. “Please note that if you have diagnosed wear or damage directly on the pipe itself, you should replace not only the unit that is damaged, but also the sealing gasket. This approach will ensure the best durability and wear resistance of the entire pipe section, and the old gasket will not become a bottleneck in the entire exhaust pipe.”

How to repair a “glushak” with your own hands

The muffler on the “fourteenth” and “fifteenth” is considered one of the most vulnerable points of the car. The fact is that due to exposure to high temperatures, the metal quickly burns out, that is, the tightness of the system is broken. Therefore, the part must be changed as soon as there is a suspicion that it is not working.

Reasons for failure

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

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

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

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

In general, all of the above factors influence service life to some extent. The car owner can easily identify all of the above faults - 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 make characteristic sounds when moving - gurgling, sharp pops, knocking.

Why is the muffler knocking?

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

it hits the body;

When moving, it touches the gas tank housing.

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

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

In some cases, the silencer begins to knock when its elements have been installed incorrectly - for example, after replacing the resonator or exhaust pipe. In this case, you will need to double-check that all fasteners and gaskets are installed correctly.

Citizens! It's simple! I had a knock and I was cured in five minutes! The pipes are connected with a clamp, and inside there is a spherical ring. But the connection is not movable. By changing the angle between the pipes at 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! Repair is a scam. They will loosen the clamp, change the degree and charge you 800. Tough!

What to do if the plug is clogged

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

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

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

Then, even with uniform movement, the car will have difficulty maintaining the set speed limit.

Black exhaust from the pipe, loss of engine dynamics.

Cleaning the muffler is a tedious and time-consuming procedure. In addition, if the pipes are clogged, then, most likely, after cleaning, other defects will be revealed - such as rust or burnouts. Therefore, it is more advisable to simply install 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, but if nothing is clogged, then you won’t notice these 2 unfortunate horses at all.

Reasons for part failure

The muffler is affected by several different factors that can lead to failure, these are:

The chemical and physical effect on the muffler metal is a natural process. It will not be possible to disassemble and clean the muffler, since the container cannot be opened, and only the attention and professionalism of the driver on the road will help protect it from impacts and stones. Diagnosing and repairing minor damage at the initial stage will help avoid serious problems in the future.

The influence of various negative factors can lead to damage to the corrugation or other parts of the muffler

Extraneous sounds in the jammer

What's the reason for a full-time employee? what don't you care about?

Yes, because I hesitated to change them every month. A month passes, and when the passengers are sitting in the rear, the muffler begins to hit the rear beam. I heard that there are silicone ones, but I can’t find them at the car market, maybe someone has heard of them?

Kalinovskie or Priora, even thicker.

Adjust the pipe normally and nothing will hit.

I adjusted it, just changed the resonator, nothing changed.

I take the factory BRT from the year I drove it and changed it, nothing drums normally.

I once installed rubber bands from Sierra, but they were cut in half and they were hard and the vibrations from the pipe were transferred to the body; the whole time the buzzing noise returned to the standard ones.

DO NOT reinvent the wheel, buy Kalina or Priora rubber bands and forget about them.

An acquaintance installed it from Kalina, it’s a bit of a stretch and there’s nothing rattling and everything becomes like family.
