Where is the pillow in the car?

In the engine compartment, the main element is the cylinder block. All other parts are mounted, mounted around it. It itself is installed on special supports that help reduce vibration from the motor, and not to transfer its car body. Such supports are made using rubber, damping unnecessary vibrations. To those who do not know what an engine cushion is, we explain: these supports are the “cushions”.

Appearance of pillows

The bottom supports are made of a pair of steel sheets. Between them is flooded with rubber, which reduces vibration.

Upper cushions are made in the form of levers, and are equipped with silent blocks. Fastening to the car body is carried out on one side, and the other side is fixed on the cylinder block. This arrangement of supports is quite strong and inexpensive in execution.

Breakdown diagnostics

It is not always possible to immediately orient from which side there is a vibration in the car, because the reason may be in a poor-quality road surface or loose fasteners of some engine parts.

One of the signs of a broken support may be a slight vibration when starting the engine.

But not all car owners attribute such a “sin” to engine pads.. It is believed that a cold engine can sometimes behave this way. Therefore, it is not uncommon for the driver to know about such a breakdown only after the engine mount has completely come off and a metal gnash appears. With this fault you can get to the nearest service station.

Ripped mount can be repaired. In the event of a break in the rubber block, only a complete replacement is required.

The issue price for passenger cars is 2000 rubles, and for oversized crossovers and SUVs - about 4000 rubles.

The cost of such work at the station will cost from 300-500 rubles for the front or side, and seven hundred for the back. But you can save by replacing yourself.

Replacing engine mounts

For those who do not know how to replace the engine mountings, we will give a step-by-step algorithm. The first action will be removing all engine protections. It is necessary to support the motor with a jack. If the work is carried out on a viewing pit, then you can use a powerful wooden board as a lining. We need one that will sustain the mass of the engine after disconnecting it from all supports.

Location of fasteners supports

We raise the maximum motor to unscrew the mount and remove the broken part. In its place we put a new one, and fasten it with fastening bolts. After that go to the rear support. Here is not so simple.

On the longitudinal axis of the car, it takes the strongest load.

Due to this, there is a deformation not only of the mating fasteners of the cushion and the body of the car, but also the bolts are bent. The motor must be raised. It is either hung on the glasses, or lifted with a jack from the bottom to ease the load on the fasteners.

If it is not possible to align the bolt, you can cut it with a grinder.

In some engines, structural elements of the exhaust system interfere. Such parts can be removed for better access to the support.

You can remove the support from the seat using oil or WD-40. They are poured over the item, which rusted and not "breaks down." For proper installation of the rear cushion on the parts shows an arrow indicating the direction of movement of the car. On it you need to navigate.

When dismounting the right engine mount, problems often create a generator or air conditioner compressor that is not advisable to be removed.

This leads to depressurization of the cooling system. A replacement of freon will cost much more than working with pillows.

Access to the right cushion in most cars can be provided by removing the right headlight and grille. Well, the problem with deformed fasteners here with the help of the grinder can not be solved. Around this place are elements of the car that are vulnerable to abrasive sparks.

A long but safe way is to cut bent bolts with a hacksaw.

Freed from the old broken engine mount, you can put a new one on this place. The assembly procedure is the reverse of the disassembly order. When installing the grille back, you need to protect your hands from cuts.

To ensure safe operation when replacing the supports, it is necessary to fix the engine well. Alone, it rarely works. We have to use the help of partners.


As a preventive measure, it may be advisable to regularly check the effort to tighten mounting bolts on the pillows. To clean the rubber bases of the supports from oil and other contamination in order to avoid material destruction. Such care will extend the life of the parts.
