Each individual VAZ 2110 engine mounting mount and all of them together are designed to provide reliable mounting while simultaneously vibration isolating the engine and gearbox on the vehicle.
Therefore, if, while driving over bumps, when changing gears or during other actions, you begin to feel vibrations and characteristic tapping and creaking in the engine area, as if the pieces of iron are hitting each other, indeed, it is the motor mounts that should be suspected.
Engine support cushion
On the VAZ 2110, the cushion is a rubber-metal part such as a silent block. On one side this part is attached to the body, on the other - to the engine cylinder block. They hold not only the engine, but also the gearbox.
This design has proven itself well - it is reliable and not expensive. But - as long as the pillows are not destroyed.
Design difference
On a VAZ 2110, the engine is usually held by three or four points at the bottom, and two or three at the top. But you should know that the 8 valve engine has a rear engine mount. The 16 valve does not have it, but it has additional supports.
Self-adjustment of VAZ 2110 valves is discussed here:
Rear support cushion for 8-valve engine
But in general, their replacement is similar.
By the way, if desired, additional support can also be installed.
Design features of the pillows of the eight-valve VAZ-2110 engine
Before you start checking and replacing engine mounts, you need to know one important thing: eight-valve and sixteen-valve engines have different mounts . The 16-valve engine does not have a rear engine mount, but does have two side mounts, which the eight-valve engine does not have. The replacement procedure on one and the other engine is almost identical, and differs only in minor nuances.
Symptoms of wear
Although it seems that it is quite difficult to determine the wear of engine mounts without the intervention of a qualified specialist, in fact, you can find out everything yourself.
The failure of the engine mount can be immediately determined by increased vibration.
In this case, the engine will operate normally, but vibration will be felt on all elements of the body, including interior elements.
The strongest vibration occurs when the engine starts and immediately after it is turned off. Sometimes you can even hear a characteristic knock , which appears due to the contact of the engine with the supports. In this list you can see the main causes of problems associated with engine mounts:
- Most often, pillows become deformed. Deformation occurs due to the exhaustion of the pillow's life.
- Rubber loses elasticity. This most often occurs due to the old age of the pillow.
- Rubber cracks, falls apart and delaminates. Often the pillow can fail as a result of high temperatures or exposure to aggressive liquids.
An old support, worn out by years of use.
And here is a half-circle crack.
In any of these cases, the pillow will no longer be able to perform its immediate functions efficiently.
Functionality check
Before changing pillows, you should check the functionality of the old ones. It may happen that the cause of vibration and knocking is not in them.
You can learn about the influence of the crankshaft sensor on engine operation in this material:
So:
- We put the VAZ 2110 on supports;
- We install a jack with a backing made of board or timber under the oil pan and jack up the engine until the cushions are freed from its weight;
- We check all the pillows, namely: • Are there any cracks on them; • How easy it is to separate them from the substrate (it is made of metal); • Are they still hard? • If no obvious deficiencies are found, and replacement is not yet necessary, check the play between the frame and the plates; • Lubricate the cushions with a protective compound, lower the motor, tighten the fasteners and nuts.
Do I need to change
There are no recommendations for replacing pillows depending on their service life, but once you determine that they are faulty, you should not delay replacing them. Vibration processes can not only worsen the comfort of the driver and passengers, but also lead to destructive processes in the engine or gearbox itself.
Having decided to repair the engine mounting elements, you need to decide whether you will change the cushions themselves or the mounts assemblies. In principle, if the metal support itself is not damaged, it can be left, replacing only the pillow.
The price of a set of pillows for a VAZ 2110 costs around 1,300 rubles. The cost of a complete set of supports is about 2,500 rubles.
For the work of replacing engine mounts or mounts at a service station, you will be charged at least 300 rubles for each.
8 valve engine
If you need a replacement on an 8-valve valve, then proceed as follows:
- Right pillow. It is necessary to unscrew: • The upper nut; • Bolts for fastening to the bracket; • Bolts under the wheel arch securing the bracket to the side member. We remove the bracket and install a new pillow, reassembling it in the reverse order.
- Left. After unscrewing the top nut, lower the motor onto the prepared support and pull out the top washer from the support. We unscrew the fastening bolts, remove the washer, after which you can replace it;
- Rear (8-valve only). Unscrew the nuts that secure the airbag to the body, then the bolts securing it to the gearbox. The new part may come with a bracket. But if it is not there, install it with the removed one and assemble all the parts in place.
Replacement
The replacement procedure should not cause much difficulty for those who have independently repaired their car more than once, especially the suspension and chassis.
If you have no experience, then we recommend contacting a service station. Only proven and reliable.
Dismantling works
Replacement has its own nuances depending on the pillows for each engine in question. We will separately talk about the repair of 8 and 16 valve engines.
8 valve engines
- Select a flat surface for repairs, place chocks under the rear wheels, and turn on the handles.
- Remove the engine protection.
- Unscrew the bolts of the generator belt tensioner, after which this belt must be removed. You will need a 13mm wrench.
- Place a jack under the car, place a strong wooden board on top and lift the engine until it releases the load from the supports.
- Using a 15 wrench, unscrew the central fastening nut of the worn pillow.
- Now use a 13mm wrench to unscrew the airbag fixing bolts mounted on the bracket.
- From below, near the right arch, 3 more bolts are unscrewed. They are responsible for connecting the bracket to the spar. You need a 17mm wrench.
- The bracket is removed, the pillow is removed and replaced with a new one.
- Next, perform assembly in reverse order.
- Place the jack under the transmission and then lift it up.
- Using a 15 wrench, unscrew the nut of the central fastening of the left pillow.
- Using a 13mm wrench, unscrew a pair of bolts securing the support, after which it is removed.
- Replace the damaged element, and then carry out the reassembly procedure.
- Remove a pair of nuts with a 17mm wrench. They secure the cushion to the body. Then a couple more nuts connecting the cushion to the gearbox are unscrewed.
- Remove the rear support.
- Using a 17mm wrench, remove the fastening nut connecting the bracket to the cushion. A new rubber part is installed in place of the old element.
- The rear support is returned to its original state by reassembly.
16 valve engine
If you have a 16 valve engine under the hood, then there are some nuances for replacement.
On 8 and 16 valve engines, dismantling and replacing the side cushions is carried out in a similar manner, there is no difference. But the front lower ones change differently.
To change the front lower mount on a 16 valve engine, you need:
- Unscrew the front lower support rod fixing bolts in relation to the front suspension cross member. For these purposes, arm yourself with a 15 key;
- Unscrew the fastening nut that holds the support to the engine bracket. You will need a pair of keys at once and both are 15. The bolt is removed;
- Remove the support, change the cushion on it or replace the entire assembly;
- Reassemble;
- In the engine compartment, unscrew the fastening bolt of the upper front support to the car body, while holding its nut by hand. This is where the key for 17 comes in handy;
- Remove the bolt and nut;
- Remove the fastening bolt of the front upper support in relation to the power unit bracket using 15mm wrenches. The bolt and nut are removed;
- The support can now be removed, the pillow or the entire assembly can be replaced;
- Assembly is performed in reverse order.
Assembly of the unit
Additional support
To make movements in the longitudinal direction smaller, you can install an additional support. It is also called a suspension bar. Mostly they can be found in online stores.
Additional support
To mount an additional support on the 8-valve power unit installed under the hood of your VAZ 2110, you will need to purchase a special bracket used to transfer the ignition module.
Reviews from those who have performed such operations claim that when starting off the car does not jerk, the engine does not become loose, which has a positive effect on the wear of the cushions.
An important useful property of modification by installing an additional support is to prevent the lower pipe from falling off the radiator, which seriously affects dozens of people.
There are a lot of opinions regarding reducing vibrations. Some consider this a useless exercise, while others, on the contrary, note significant improvements in the behavior of the car.
Let's sum it up
Taking into account the above information, it becomes clear that replacing the engine mounts/mounts of the VAZ 2110 and a number of other models is not a complicated procedure. However, before carrying out work, you need to accurately determine the need for replacement itself, as well as which pillows need to be changed.
We also recommend reading the article on how to replace the VAZ 2110 clutch with your own hands. From this article you will learn about the signs that a clutch needs to be replaced, as well as how to change the clutch on a 2110 yourself in a regular garage.
Finally, we note that operating a car with faulty engine mounts affects not only comfort, but also the service life of the car’s components, as well as the body. For this reason, if the engine vibrates strongly, this is a reason to check the supports and completely/partially replace the power unit support pads.
What is needed for repairs
First, you need to determine which support on the VAZ 2110 engine should be changed (if you do not want to change all the damper mounts at once). To do this, you need to do an independent inspection of these parts. Sometimes, the power plant seems to be tilted horizontally on one side or tilted along the central axis of the car. This is the first sign to replace the damper mounts.
Two cushions (side) secure the engine to the left and right side members in the engine compartment. And one (rear) fixes the motor to the bottom. Therefore, it is necessary to lift the machine on a lift or install it on a viewing hole. The wear is immediately visible. The rubber has tears and core failure. Depending on the result of visual diagnostics, you should purchase the required number of parts for installation.
You will need a tool. In most cases, a standard locksmith set consisting of open-end and box-end wrenches with heads will be sufficient. In addition, to replace engine mounts on a VAZ 2110 you will need a rolling jack and a pair of short boards. It is advisable to have electricity and a cutting machine with a disc, since you may have to cut off the mounting bolts.
Helpful information! A couple of hours before repairs, it is strongly recommended to apply universal lubricant “Liquid Key” to the threaded connections. Damper supports are changed very rarely, therefore, unscrewing them without prior preparation is quite difficult.
DIY VAZ 2112 repair
Domestic cars are attractive due to their affordable price and ease of maintenance.
Repairing a VAZ 2112 with your own hands allows you to learn more about the car. VAZ models often have congenital defects and have great potential for tuning. And that's why I'm a frequent visitor to the service station. Photo of the VAZ 2112 car.
VAZ-2112 (LADA 2112) is a Russian car produced by the Volga Automobile Plant. The model was mass-produced for 10 years - from 1998 to 2008. The Lada Priora replaced the Zhiguli (the popular name for the 2112 model).
VAZ 2112 is built on the VAZ 2110 platform. The new model was produced in a hatchback body. Structurally, the two models are identical, only the VAZ 2112 has a reduced body length. The rear seat is borrowed from the VAZ 2111.
Additional support
In order to reduce engine movement in the longitudinal direction, an additional support (suspension rod) can be installed. They are mainly purchased in online stores. An additional support is installed on all types of VAZ 2110, but it has its own characteristics.
For an 8-valve model, you also need a special bracket that is used to carry the ignition module. Those who installed such a bar claim that when the car starts moving, the engine does not wobble, the cushions do not wear out as much, and the lower hose does not come off the radiator (which is what dozens of people “suffer from”).
Opinions differ regarding the decrease/increase in vibrations.

Reasons for failure
Among all the reasons for the failure of engine mounts, the most basic can be identified:
- Spent life of engine mounts due to mechanical impact.
- Wear of rubber elements due to constant changes in ambient temperatures.
Before you go to the store, you should determine whether it is worth changing only the cushions or the entire support assembly. Depending on the condition of the metal supports and the absence of damage on it, you can replace only its rubberized component.
- The price of a set of pillows for a 16-valve VAZ-2112 is about 1,500 rubles, and the assembled supports are 3,000 rubles.
- Work on replacing pillows in car services varies within 500 rubles per piece, however, we believe that this is a waste of money, and we suggest that you carry out this work yourself, since no special skills are required for this.
