The engine mount on any domestic car is a rubber-metal silent block on a bracket. It connects the cylinder block body to the stationary parts of the car. On the VAZ 2114, the factory provides three such supports:
- the front one, also known as the bottom one, connects the crankcase to the beam;
- the right one, also known as the side one – between the engine and the spar;
- rear - attached to the gearbox housing and body.
Also, sometimes an additional mount is installed on the VAZ 2114, which is attached to the cross member on one side and to the clutch housing on the other.
It is widely believed that the main task of airbags is to provide ride comfort. This is only partly true. In fact, their main task is to minimize the transmission of engine vibrations to transmission parts. With a rigid connection, the gearbox would become a consumable item; in 30-40 thousand kilometers its “internals” would wear out completely. Therefore, in particular, rubber in silent blocks cannot be replaced with polyurethane.
Step-by-step instructions for replacing VAZ 2114 engine mounts/mounts.
Preparatory stage of work.
Having determined by knocking from the engine compartment, vibrations in the body or visual inspection the need to replace the engine, do not delay this procedure, otherwise you may end up with a much more expensive repair than simply replacing the supports. Moreover, even a beginner who has never encountered this type of work before can carry it out. You just need to prepare a certain set of tools, spare parts and simply follow the instructions given below.
This set consists of:
- jack;
- new engine mounts;
- spanners;
- ratchet;
- small board;
- set of socket heads and wrenches.
Depending on the condition of the car and its components, you may also need a rust remover.
When everything you need is at hand, you can begin the replacement process itself.
Replacing the front airbag.
- We drive the car onto an overpass or “pit”, in general, we do everything to make it convenient to work under it.
- We protect ourselves with stops.
- For our safety, we remove the terminals from the battery.
- Using a wooden plank, carefully (so as not to touch the radiator and fan) jack up the engine in the place where the support will be replaced.
- We loosen the protection fasteners, remove the old support and install a new one in its place. All threaded connections are pre-lubricated with sealant.
- If necessary, repeat all the above steps with another (other, photo below) pillows.
- We install the dismantled parts in the reverse order described above.

Replacing the left/side airbag.
Choosing a support
The cost of supports starts from 500 rubles per piece. It all depends on the manufacturer, manufacturing method and materials used.
The front airbag is the most expensive of the three.
As a rule, prices for the front “cushion” are slightly higher than for the left and rear ones, since this is due to the much greater load-bearing capacity of the part and the use of the largest amount of materials.
The average cost for high-quality supports is about 1,000 rubles per piece, and a complete set can be purchased for just over 3,000 rubles.
All supports are in one place, ready for replacement.
In order to replace the supports, it is not necessary to contact a service center, because such work can be easily done with your own hands.
You can suspect that something is wrong with the engine mounts of your car by the characteristic knocking noise under the hood and vibrations while driving.
Today we’ll talk about what engine mounts or mounts are, what they serve and how they are replaced.

Newer VAZs, despite criticism, are still evolving compared to their predecessors. Thus, in newer models, instead of a standard engine mount, the manufacturer used a so-called engine mount, the appearance of which made it possible to significantly increase the level of comfort in domestically produced cars.
The VAZ 2114 engine mounts act as shock absorbers (dampers) that dampen vibrations coming from the power unit. Such pillows will not allow vibrations to transfer to the body, and then into the interior of the car, which makes the ride more comfortable and enjoyable. In addition, the airbags soften the impacts coming from the wheels when driving through areas with poor road surfaces. Engine mounts are practically the same silent blocks that are used in the design of the chassis.
There are three pillows on the “fourteenths”:
- The front (also called the bottom) connects the crankcase to the beam;
- Right (or side - located between the motor and the spar);
- Rear – connects the box and the body.
Engine mounts are constantly under heavy load, even when the car is just standing still, which cannot but affect their condition. Over time, engine mounts, made of durable rubber, become unusable and require replacement, which is indicated to the car owner by characteristic signs.
What is this?
If we talk about the VAZ 2114 model, then there are three supports, two of which are intended directly for the gearbox, and another one for the engine itself.
The main purpose of pillows is to reduce vibrations.
When the car drives, serious vibrations occur, which are transmitted to the body from the power unit. To ensure the necessary level of comfort while driving and not to be distracted by extraneous noise or shaking, special supports are mounted on the car. If you remove them, driving a VAZ 2114 can be compared to riding an old wooden cart.
Causes of malfunctions
The most important problem that pillows face is the loss of elasticity of the material. This is due to the fact that the supports are made of rubber. Over time and with use, these elements lose their original characteristics. Various factors accelerate the wear process of bearings:
- Regular exercise;
- Long service life;
- Cold;
- Heat;
- Temperature changes, etc.
If elasticity decreases, this entails the formation of cracks and delamination of the material.
Replacement is purely a matter of time. But the procedure for changing the front and all other pillows should be carried out on time. If you drive for a long time with worn out bearings, this will result in a negative impact on engine performance. Then the repair will cost much more than the cost of new supports.
The main advice is to periodically check the condition of the supports for wear. If you detect a fault in a timely manner, you can replace it yourself and significantly save on car repairs.
Price issue
If you do everything correctly and in a timely manner, then your costs will be insignificant. You will have to purchase new supports and contact a car service. Of course, it is quite possible to do it on your own. This is a matter of desire and availability of appropriate skills.
How much will it cost to replace engine mounts? We suggest that you familiarize yourself with the current prices for the VAZ 2114.
Detail | Minimum cost | average price |
Front airbag | 600 rubles | 1200 rubles |
Rear cushion | 500 rubles | 900 rubles |
Left pillow | 500 rubles | 900 rubles |
Set of three supports | 3500 rubles | 5000 rubles |
Car service | 1500 rubles | 2500-3000 rubles |
There is no need to pay someone, since the replacement can be done by yourself.
Signs of faulty engine mounts:
- The appearance of strong vibration, especially at low speeds;
- Metallic knocking coming from under the hood;
- From time to time there is a sound similar to the ticking of a clock;
- Visual damage (cracks on the surface of the cushions, large play in the joints).
If you do not respond in time to the above-described signs of faulty engine mounts, the consequences can be quite unpleasant. Due to the increase in backlash, the engine will start to “spin”, and as a result, the mounts, body, and other dependent components will suffer. Misalignment may cause the cooling fan to hit the radiator or its grille.
To replace the engine mount you will need:
- Two jacks;
- Motor stands;
- A set of keys;
- Inspection hole;
- New engine mounts for VAZ 2114.
Replacement result
After assembling all the parts, you should check whether the replacement was carried out correctly. To do this, you need to start the car and drive the car on a rough road.
If no more knocks bother you, and the car doesn’t shake like a tractor, then the job was done correctly. Otherwise, you should check whether you have placed the pillows evenly.
In order to extend the service life of the engine mounts, you should check that the bolts are well tightened and periodically remove dirt from them. Only regular monitoring will help delay the occurrence of engine mount malfunctions.
Replacing the front and rear engine mounts of a VAZ 2114
The engine mount on any domestic car is a rubber-metal silent block on a bracket. It connects the cylinder block body to the stationary parts of the car. On the VAZ 2114, the factory provides three such supports:
- the front one, also known as the bottom one, connects the crankcase to the beam;
- the right one, also known as the side one – between the engine and the spar;
- rear - attached to the gearbox housing and body.
Also, sometimes an additional mount is installed on the VAZ 2114, which is attached to the cross member on one side and to the clutch housing on the other.
Signs of wear
Since the function of the engine mount is to dampen vibrations, if they are noticeable even at idle, this indicates a problem. Among other signs of wear on the airbags on the VAZ 2114:
- Vibration of the gearshift lever. This indicates that all motor vibrations are transmitted to the box.
- If you open the hood, strong vibrations of the engine are visible.
- Uneven car operation. The fact is that when the silent blocks are heavily worn, the crankcase begins to move slightly relative to the clutch. Because of this, the crankshaft position sensor (CPS) constantly produces different signals. The ECU is forced to mistakenly “catch” the revolutions to eliminate the imbalance.
Self-replacement
Before replacing the pillows, it is necessary to diagnose their condition. The condition of any silent blocks is checked with a mount: with its help you need to influence the support, simulating the movements of the engine during operation. If:
- rubber ruptures are visible,
- the bushing of the silent block touches the joints,
- the motor moves easily when pressed and hits the protection,
- the support bracket is broken,
the part needs to be replaced. Even if the signs of wear are not so noticeable (for example, the rubber is cracked but not torn), it is better to replace them as a set. Silent blocks lose their elasticity over time and begin to perform their functions poorly.
There are regular and reinforced supports for the VAZ 2114 on sale. The second type uses a harder rubber compound, but they are more durable only in quiet driving mode. Fans of sharp starts and braking will have to change any of them every 15-20 thousand; for other drivers they can last 50 thousand kilometers. This is the answer to the question of how long the supports last.
Front engine support VAZ 2114
On a VAZ 2114, the supports can be replaced independently, without contacting a car service center. It is more convenient to use a pit or overpass, but you can do without them. To do this, the car is jacked up and placed on supports (bricks or tree stumps). If crankcase protection is installed, it must be removed.
Replacing the front support. You need to jack up the oil pan. First, use a 17mm head to unscrew the 4 bolts securing the bracket to the crankcase, then the silent block bolt. To remove the bolt, you need to use a jack to get it into a position where the engine will not put all its weight on it. When installing a spare part, it is important to lubricate the silent block bolt well: not only the threaded part, but also the body. It is in contact with the metal sleeve, so it can stick.
Side engine support VAZ 2114
Replacing the right support is similar, with the difference that it is better to jack the gearbox housing rather than the engine. Another option is to install a jack in the area of the oil filter housing. It is attached to the crankcase with three bolts. Another trick is that the right pillow needs to be changed by two people. Without a side stop, the motor moves up, not down. The jack will not help here, so an assistant must press on it so that the silent block bolt can be secured.
Replacement of the rear support is the most difficult task if done without a pit or lift, requiring some skill in performing auto mechanic work and perseverance. It is located at the connection between the engine and gearbox, so you will have to work in a confined space. In addition, when unscrewing the bolts from the body, the key may rest against the gearbox housing.
Self-replacement of VAZ 2114 engine mount
How to replace a VAZ 2114 engine mount will be discussed in our article. The power unit of any vehicle begins to vibrate strongly from the moment it is started, and if its vibrations (which increase with power gain) are not suppressed, one can expect dire consequences for the car frame.
Despite the fact that on older models of the domestic automobile industry, special cushions made of dense and durable rubber acted as dampers for engine vibrations, but the engine still continues to lie on the frame.
The designers have significantly modernized the engine compartment of the latest generation front-wheel drive models (for example, on the VAZ-2114), adding specially designed cushions, which are now also supports for the power unit.
However, under our operating conditions for automotive vehicles, these elements are subject to high loads and wear out faster. In this publication, we will discuss in what cases it is necessary to replace the engine mounts of a VAZ-2114, and how to carry it out yourself.
How to choose engine mounts?
When choosing engine mounts, you should pay attention to the quality of the product. If you have the opportunity to get acquainted with it by opening the box in the store, do so. Evaluate the products based on the quality of metal insulation and whether there is an anti-corrosion coating. Check the rubber element for elasticity.
Generally, the front support is more expensive than the rest. The price of the engine mount will be about 1000 rubles . The left and rear airbags cost an average of 700 rubles each.
When purchasing, check the article number indicated on the box so as not to get a fake in packaging similar to the original:
- Front – 2108-1001015-10
- Rear – 2108-1001031-10
- Left – 2108-1001040-10
In addition to the original engine mounts and their analogues, you can find reinforced ones on the market. They are considered stronger and allow the engine to be secured more firmly. But they also have their disadvantages, one of the most noticeable is strong vibration on the body. This is due to the fact that the damping element is made of dense rubber. The installation of such supports is not required on a civilian vehicle, and their cost is twice as high as that of a stock one.
Replacing an engine mount on a VAZ 2114 with your own hands is not a labor-intensive process. When you have chosen the right parts and done the job correctly, unnecessary vibration, sounds and knocks from the engine compartment should disappear. If the malfunction is still observed, check whether the cushions are level in their places.
To extend the life of new supports, you need to periodically check the tightness of the bolts and clean the rubber damper from dirt. This should be done regularly, especially if the car is driven in rural areas or on poorly paved roads.
Design and technological features
Since in the “fourteenth” model the entire load from the engine falls on the front suspension, accordingly, the chassis is made of materials with an increased margin of safety, and its design must strictly comply with established standards. Durable rubber mounts of the VAZ-2114 engine are used as a damper for vibrations of the power unit under various loads.
Since high demands are placed on this part, it is extremely important to purchase only original and certified supports, since only they are suitable for use in our conditions.
In the design of the front part of the car frame and its suspension, the engine mount is one of the important elements, while its independent replacement is quite within the capabilities of a car owner who has even the most minimal concepts in plumbing.
The main thing in the repair process is to complete the entire technological sequence of actions, then the installed part will serve for a long period of time.
When do you need to change engine mounts on a VAZ-2114?
Since rubber elements are included in the design of the supports, during operation they are subject to increased loads, wear out and lose their properties. This can be judged by the noticeable vibration that is clearly felt inside the car. The following factors affect the service life of the element:
- load;
- temperature regime;
- operating conditions of the vehicle.
It is very important to replace the airbag in a timely manner; if this is not done, the part will simply become unsuitable for further use, and only then will cause a more complex and expensive repair of the power unit suspension.
If you hear extraneous noises in the area of the engine compartment when driving, and suddenly noticeable vibration appears in the interior of the VAZ-2114, it is necessary to perform a visual inspection of the engine mounts, and if damage is found, replace them immediately.
Replacing the engine mount
To perform this activity, you should purchase a set of power unit supports, since it is not practical to change them one by one. To replace these elements yourself, you will need the following tools:
- Set of wrenches.
- Scrap.
- A pair of powerful jacks.
- Glue.
- Durable cable.
Advice! It is worth inviting an assistant in advance, since during certain stages of the repair it will be necessary to lift quite a lot of weight. We recommend using an engine disassembly stand for these purposes.
The process for replacing pillows varies. Sequence of actions when replacing the front engine mount:
- it is necessary to immobilize the car in advance by tightening the parking brake and placing shoes under the wheels;
- you can only get to the support after dismantling the upper protection of the power unit;
- Let's start jacking up the engine. To avoid damaging it when doing this, it is worth preparing a strong board in advance, which is placed between the jack pusher and the bottom of the motor;
- you can unscrew the bolt securing the pillow to the bracket, since it is no longer under load;
- We carry out a similar procedure with the bolt securing the support to the engine;
- remove the worn element and install a new one.
Sequence of actions when replacing the rear and side supports:
- The car's transmission must be hooked up with a cable, and then a jack must be placed under it;
- loosen the bolt securing the gearbox to the support;
- We perform a similar procedure with the nuts securing the power unit cushion;
- Having jacked up and raised the gearbox, remove the nuts and bolts securing the cushion;
- remove the worn out part and install a new one, assembling everything in the reverse order.
The side cushions of the VAZ-2114 engine change in the same way. The only thing is that if the starter is large, it will need to be dismantled, since it will not be possible to get to the support mounts properly because of it.
This is the entire process of replacing worn out engine mounts. As you can see, it will not cause any particular difficulties, and its timely and competent implementation will help to avoid serious problems in the future and save on expensive repairs.
Attention! I advise you to save not only on repairs, but also on fuel. How to do this - here is a separate article on this topic.
How to change supports
To replace, you will need to purchase front, left and rear airbags. Experts advise replacing the entire set during repairs, since after replacing one part, another one may break after a while. The average cost of parts is 2000 rubles. If you have the necessary tools, you can do the repair yourself and save on car service.
List of tools
To replace the pillows we will need:
- 2 good jacks;
- metalworking tools;
- scrap;
- steel rope;
- glue.
Tip: At some stages you will need to lift a lot of weight, so it would be a good idea to invite a neighbor or a fellow car enthusiast here.
Replacing the front airbag
The repair of each support has its own characteristics. Replacing the front airbag is carried out as follows:
- Put the car in 1st gear or the handbrake so that it does not move.
- To gain access to the support, remove the upper engine protection.
- Raise the engine with a jack. To avoid damaging its lower part or other elements, place a wooden board underneath.
- When we have freed the support from the load, we can unscrew the bolt that connects it to the bracket.
- We unscrew the bolts connecting the pillow to the motor.
Removing the bolt that secures the cushion to the engine - We remove the old part and install the new one.
Replacing the rear cushion
Here we will need a steel cable to make it more convenient to work with fasteners.
- We hook up the gearbox with a cable and install a jack under it.
- Slightly press out the bolt connecting the gearbox to the support.
- Unscrew the nuts securing the support to the body.
Loosening the nuts that connect the cushion to the body - Raise the gearbox and unscrew the nuts and bolts.
Unscrew the bolt and nuts - We replace and reassemble in reverse order.
When replacing the side airbag, you will need to perform the same steps. If you have a large starter installed, it will need to be removed to get to the bolt. It is better to coat rubber products with a special protective substance - this will ensure a long service life of the parts. After completing the repair, do not forget to test the car. If during movement the knocking stops and the vibration becomes almost unnoticeable, then everything was done correctly.
Signs of wear
Due to the presence of rubber inserts, the cushion loses elasticity during operation and can no longer dampen vibration, which is noticeably felt in the car interior.
Other signs of wear include:
- the appearance of a metallic sound under the hood;
- a periodically appearing sound reminiscent of a clock ticking;
- various damages that can be detected visually, such as cracks in the cushions.
Engine mounts are one of the most loaded parts in a car; they experience loads even if the car is stationary. Therefore, it is very important to pay attention to signs of wear and respond to malfunctions in a timely manner so that you do not have to later change the engine mount or repair the body.
Experts advise purchasing pillows only from a trusted manufacturer that provides a guarantee on the product. A low-quality part, firstly, will not cope with its task properly, and secondly, it will very quickly become unusable.
Replacing engine mount VAZ 2114
Replacement of the front support is carried out in the following sequence:
- The car should be placed on a flat surface and put on the handbrake.
- Unscrew all the bolts to dismantle the VAZ 2114 engine mount protection.
- If there is rust on the bolts, it is better to treat them with a special WD-40 agent to protect them from corrosion.
- Very carefully, so as not to damage anything, place a jack under the car and lift the engine.
Important: a spacer, for example a wooden block, must be installed between the jack and the engine.
Replacing the left engine mount of a VAZ 2114 is done in the same way as the right one, only you will also need a cable during the work. With its help, you need to pick up the gearbox and place a jack under it. If the car has a stator, it should be removed. Then remove the bolt connecting the support and bracket. Take out the old pillow, install a new one in its place and reassemble in reverse order.
When all work is completed, be sure to check the correct installation of new parts and the reliability of the connections. After a visual check, you should start the car and drive on an uneven surface. If there are no noises, then everything has been done correctly and you can safely operate the machine.
Replacement
We have already noted that there are a total of three supports on the VAZ 2114. But it’s not uncommon for car owners to decide to install a fourth—an additional airbag. It serves to connect the crankcase and transverse the front suspension. This reduces wear and vibration and increases the level of comfort. But keep in mind that with such a modification you will have to look for a new place for the ignition module.
Now let's talk in more detail about the three standard pillows. Replacement of each of them is carried out in a certain sequence and according to the appropriate algorithm.
Front
To change the front engine mount, follow the instructions.
- Drive the car into a pit with a flat surface. Stop the wheels, turn on the handbrake, and put the transmission in first gear. This is a guarantee that the car will not roll away unexpectedly for you.
- Remove the crankcase protection and give yourself access to the front airbag.
- If the car has been in service for more than a year, and you haven’t touched the supports for a long time, then be sure to treat all fasteners with WD40 or another effective “fighter” against rust.
- Using a jack, you need to slightly raise the power unit. In this case, be sure to use a wooden beam as a spacer so as not to damage the motor. Keep an eye on the radiator and fan while lifting the engine. They should not break, otherwise you will not avoid serious expenses.
- There is a rather long bolt on the body cross member. It secures the support and bracket. It needs to be unscrewed.
- Now the bolts that connect the motor block and the pillow are unscrewed.
- All that remains is to remove the damaged element and replace it with a new one.
- Assembly is performed strictly in reverse order.
Engine pad
Left
Here, in addition to the standard set of tools, you will also need a cable.
- Using a cable, pick up the gearbox and place a jack under it.
- If your car has a large stator (an old-style device), you cannot do without dismantling it.
- Now we remove the bolt that connects the bracket and the support.
- Remove the worn out cushion.
- Place the new element in place and reassemble.
- Before firmly tightening all the fasteners, make sure that everything is exactly in place.
Path to the left pillow
Rear
A cable will also come in handy here. How exactly to perform the replacement? Simple enough.
- By analogy with the left support, pick up the gearbox and place your jack under it.
- Loosen the fasteners that secure the gearbox and rear support slightly.
- Loosen your grip on the two nuts on the body that hold the rubber mount in place.
- Raise the gearbox slightly with a jack and unscrew both nuts.
- The bolts that hold the pillow are unscrewed from the box itself.
- Remove the damaged element, install a new support and reassemble in the reverse order.
- If there is rust on the fasteners, we recommend cleaning it or replacing the bolts with similar new ones.
Changing these elements is not difficult, but we still recommend that you first consult with specialists and watch training video instructions. This will allow you to take on the work with your own hands more confidently and save an impressive amount of money on car service services.
To ensure that new engine and gearbox components serve for a long time and reliably, we recommend that you do not skimp on their purchase. Buy high-quality products right away that will last you many years.
