Engine mounts on VAZ 2109 cars are responsible for reducing and eliminating vibrations emanating from engine operation and transmitted to the car body.
Every motorist should be able to replace them with his own hands. There is nothing complicated in working with supports, but competent repairs can significantly extend the life of the car and get rid of quickly annoying vibrations and noise.
Element appearance
How to check engine mounts on a VAZ 2114?
To diagnose the mechanism we need:
- A pair of jacks;
- Bar or board;
- Mount.
The check occurs in order:
- We drive the car onto a straight platform or into a garage with a flat floor.
- Raise one of the front wheels using a jack. Then we place a second jack under the engine pan and press it against it, through a board or block, to relieve the tension on the cushions.
- We lie down under the car and inspect the engine mounts. There should be no cracks or tears on the rubber elements. Also, they should not be hardened or peeled off from the metal part.
When a visual inspection does not help to detect the problematic element, it is worth checking for the presence of play between the support and the body. To ensure a complete inspection, use a pry bar to tilt the mechanism to the side.
If problems are identified in the elements, then it is better to immediately begin replacing the engine mount, since the motor is not securely mounted and because of this, other pillows receive a load higher than that for which they are designed. Subsequently, they may also fail, which will further weaken the reliability of the structure.
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.

Set of three supports
There is no need to pay someone, since the replacement can be done by yourself.
Replacing the front support
- Place the car on a level surface. Be sure to raise the handbrake or engage first gear. For safety, you can support the rear wheels.
- Remove the engine protection to gain access to the mounts.
- To remove the load from the support, place a jack under the oil pan and raise the engine. It is imperative to place a spacer between these elements in the form of a board.
- When the engine is supported by the jack, we inspect the mounting location of the cushion. We unscrew the bolt that connects the bracket to the support.
- After this, you can disconnect the pillow from the motor unit.
- We clean the fixation points and install the new part in the reverse order.
It is possible that in order to replace the front cushion, you will need to further lift the engine, since the mounting location of the old one has been worn out.
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 the left support
- The beginning of the replacement actions coincides with the previous example, but in this case we place the jack under the gearbox.
- When the support is freed from the load, unscrew the bolt securing it to the body.
- Then unscrew the two bolts that attach the cushion to the gearbox housing.
- We also clean the contact area and install a new part.
Inspect the condition of the bolts before installing the support; they may need to be 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.
Replacing the rear support
- Just like with the left cushion, we need to place a jack under the gearbox.
- First, unscrew the bolts securing the support to the car body, and then to the box body.
- We clean the mounting area and install a new part.
Having finished the work, we check the correctness of the actions performed and the reliability of the connections. Afterwards you can start the engine.
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.
Problems when paying with bank cards
Sometimes difficulties may arise when paying with Visa/MasterCard bank cards. The most common of them:
- There is a restriction on the card for paying for online purchases
- A plastic card is not intended for making payments online.
- The plastic card is not activated for making payments online.
