The engine mount is an important part, it is a support for supporting the car’s engine, suppressing vibrations from the engine, as well as the suspension and body. The working cushion extends the service life of the motor, so you need to monitor the condition of this part.
The support system on your car can include up to 5 elements - right, left, front, rear, as well as front lower and upper.
Signs of a malfunction that require you to contact a repair shop
- Vibrations are felt while the engine is running.
- Shocks occur when driving and when changing gears at high speeds.
- The gearshift lever is shaking.
- The engine or transmission is knocking.
- When the car starts moving and when stopping, metallic clicks are heard.
- When driving on bad roads, a grinding and knocking noise is heard under the hood.
Typically, such signs begin to appear after 100 thousand kilometers or later. In any case, it is better to immediately pay attention to them and have the car diagnosed at a car service center.
CAUSES OF MALFUNCTION
- Natural wear and tear on engine mounts
- Extreme driving style reduces the service life several times.
- Constant uneven operation of the engine can lead to breakage of the drop-shaped support.
- Working fluids (engine and transmission oil, coolers, brake fluid) upon contact with a rubber element, melt it.
- The entry of dirt particles between the plates destroys the rubber and acts as an abrasive on aluminum.
- Temperature changes affect the seal, which loses its plasticity and becomes covered with cracks.
DIAGNOSTICS
You can test the condition of the supports yourself. The top cushion, as a rule, is clearly visible - it can be inspected for deformation of the rubber insert. And to check the condition of the left, right and lower engine mount you will need an assistant who will sit behind the wheel of the car:
The condition 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 pillows touches the joints,
- the motor moves easily when pressed and hits the protection,
REPAIR
The supports cannot be restored, only replaced. The repair is complicated by the fact that it is possible to dismantle the airbag after dismantling the radiator or air conditioning compressor. If you have to remove the compressor, then replacing the engine mounts (mounts) is complemented by the service of refilling the air conditioner.
After installing new pillows, it is necessary to adjust the position of the car engine.
