Replacing engine mounts on a VAZ 2110 with your own hands in the garage

Design features

If you have a “ten” with an 8-valve engine, then the design provides two side and one rear support;

On a 16 valve engine there are two side mounts, one lower and one upper.

It is important to note that 8 valve engines on the 10 have a rear engine mount, while on the 16 valve there is none. But such motors can boast of having additional supports.

Regardless of the design, the replacement procedure is performed using a similar method.

Malfunctions

In fact, it is quite easy to detect failed airbags, since engine vibrations will immediately increase.

If the power unit is working normally, but the body is shaking, vibration is felt on the steering rack, pedals, and dashboard, then there is no doubt that the engine mounts are worn out.

The vibration peak occurs when the engine starts and when it is turned off. If the rubber elements are completely worn out, then a knocking noise will begin to appear. It is caused by contact of engine elements with the supports.

To make sure the cushions are worn, turn on the engine, lift the hood, and visually inspect the supports and cushions. By placing your hand on the engine, you will tactilely feel an increase in vibrations compared to the normal behavior of the car.

There may be several reasons for problems.

Is replacement required?

If you find that the rear airbag or any other airbag has begun to wear out, you should under no circumstances delay repairs.

In addition to the discomfort of the driver and passengers when the car is moving, you risk delaying the breakdown until the moment when destructive processes begin in the operation of the gearbox and power unit.

When starting to repair engine mounts, you should think about whether it is worth changing the cushions separately, or replacing the mounts as a whole.

If the support is not damaged, it is not necessary to replace it. That is, in such situations it is enough to simply replace the pillow. A set of new pillows for a VAZ 2110 today costs about 1.3 thousand rubles. A set of supports will cost you 2.5 thousand rubles.

Doing the work yourself or contacting a service station is your choice. But you should know that you will be charged at least 300 rubles for replacing one pillow.

Useful tips

Please note that when engine vibrations occur, you should not always immediately change all the supports “in a circle”. It happens that even on a relatively “fresh” car, only one element fails, while others are quite suitable for further use. This occurs as a result of technical fluids getting into contact with the rubber part of the cushion, etc.

However, as for basic recommendations, if the car has a mileage of about 80-100 thousand km. and more, and all engine mounts have the same service life and have begun to fail, it is better to immediately replace all such mounts.

It is also important to select only original products or high-quality analogues for replacement, as well as purchase parts from trusted sellers. The fact is that there are a large number of spare parts on the market for VAZ cars, but not all of them are of high quality. Moreover, you often come across cheap fakes of an original of unknown origin.

Functionality check

Before you start replacing the pillows, it is recommended to check whether they have really lost their functionality. It is likely that vibrations can occur for other reasons.

To check you need to do the following operations:

• Place the car on stands;
• Place a jack under the oil pan, placing a block or board at the same time;
• Raise the engine until the mounts relieve the weight of the engine;
• Check the pillows;
• Inspect them for cracks;
• Check if they come off easily from the metal backing;
• Has the original hardness of the material been preserved, or has it become too elastic;
• If no visual defects are found, check the play between the plates and the frame;
• Treat the cushions with protective compounds, return the engine to its place;
• Sometimes, to return the supports with cushions to normal operation, it is enough to tighten the fastening nuts.

If the check shows that the pillows have already served their purpose, then the only correct solution is to replace them. These elements are not subject to restoration.

Signs and causes of malfunction of VAZ 2110 engine mounts

1. A strong hum in the cabin while the engine is running often indicates hard contact of the power unit with body elements. This phenomenon usually indicates the destruction of one of the supports on which the motor and gearbox connected together should rest. If their rubber cracks or even breaks away from the metal base, then the power unit receives an additional unwanted degree of freedom, creating noise.
2. A dull knock can also be heard when driving away sharply, due to the engine being misaligned on torn mounts.
3. In turn, the torn support is “given away” by a dull knock every time you press the accelerator and every time you release the gas and switch to engine braking mode.

Jack up the car engine. Using a 17mm wrench, unscrew the two bolts securing the rear support to the body. Then, using a 19mm wrench, disconnect the mountings of the support to the gearbox by unscrewing the two bolts.

Engine mounts are support elements that are designed to support the engine and increase its service life. The classic engine mount has a steel body and a thick rubber mount.

The most important function of engine mounts is to dampen vibrations coming from the engine.

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

1. Select a flat surface for repairs, place chocks under the rear wheels, and turn on the handles.
2. Remove the engine protection.
3. Unscrew the bolts of the generator belt tensioner, after which this belt must be removed. You will need a 13mm wrench.
4. 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.
5. Using a 15 wrench, unscrew the central fastening nut of the worn pillow.
6. Now use a 13mm wrench to unscrew the airbag fixing bolts mounted on the bracket.
7. 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.
8. The bracket is removed, the pillow is removed and replaced with a new one.
9. Next, perform assembly in reverse order.
10. Place the jack under the transmission and then lift it up.
11. Using a 15 wrench, unscrew the nut of the central fastening of the left pillow.
12. Using a 13mm wrench, unscrew a pair of bolts securing the support, after which it is removed.
13. Replace the damaged element, and then carry out the reassembly procedure.
14. 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.
15. Remove the rear support.
16. 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.
17. 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.

Prevention measures

To prevent breakdowns, it is best to carry out periodic maintenance. This way you will spend much less effort and time on repairs.

Preventive measures include:

• Periodic check of bolt tightness;
• Removing dirt and oil traces from the rubber elements of the engine mounts with a dry rag;
• Regular repetition of these activities every 4 months.

In practice, even a relative beginner in the field of do-it-yourself repairs takes no more than 5 hours to replace engine mounts. But this allows you to develop your own skills, as well as save a decent amount of money on the services of service stations.

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.

Locksmith kit

Rolling jack

A couple of short boards

Angle grinder (grinder)

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.

Manufacturers and prices of analogues

Powertrain cushions for Lada Priora are produced by many manufacturers. The most common brands are:

• BRT - parts from the famous Balakovo Rubber Products Plant;
• Lada Detal – original Lada spare parts from conveyor suppliers, in particular AvtoVAZ subsidiary VIS;
• Riginal is a fairly young brand of PKF Niagara.

Technologies of the future - rods of a new type are produced under this brand.

The cost of spare parts from these manufacturers is approximately the same, the difference in price depends mainly on the specific store. Some companies supply kits for replacing all suspension elements of the power unit at once. Such a purchase is usually more profitable than purchasing spare parts separately.

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.

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.

Installing an additional gearbox cushion

The Priora already has the holes necessary to install this pillow, so in addition to the spare part itself with article number 2110-1001280, you will only need fasteners:

• 2 bolts M12x75.
• 2 self-locking nuts M12.
• 4 washers for M12 bolts.
• 2 bolts M10x30 with a thread pitch of 1.25 (for some cars a thread pitch of 1.5 is suitable).
• 2 engravers for M10 bolts. 8 wide washers for M10 (can be replaced with a smaller number when using thick washers, for example, from the cylinder head).

The replacement technology itself

• The part is attached to the gearbox bracket using M12 bolts with self-locking nuts.
• The washers are placed under the bolt head and under the nut.
• M10 bolts are screwed into the body. Between it and the rod body, you need to place washers so that the rubber rod does not touch the body.

To replace this rod, which will also be required over time, just unscrew the fasteners and replace the old one with a new one.

The good condition of the Priora engine mounts is the key to comfortable movement. At the same time, if you have a suitable tool, replacing components will not be difficult.

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.
