The symptoms of a broken engine mount include:
The engine vibrates obviously when the car reverses;
There is obvious jitter when the car starts;
The engine vibrates obviously when the car is cold, and it has a noticeable improvement after the car is warmed up;
The steering wheel vibrates when idling, the brake pedal has obvious vibration.
The main effects of the bad engine mount are idling, steering wheel shaking and violent shaking of the car body.
Engine Mount is the rubber block placed between the engine and the frame. Since the engine will generate some vibrations during operation, in order to prevent the engine from transmitting these vibrations to the cockpit during the manufacturing process of the automobile, the automobile engineers use rubber pads to fix between the engine feet and the frame in the manufacturing process, which can effectively reduce the vibration and buffering of the engine during work, and make the engine run more smoothly and stably.
When the engine is working, it will generate a certain amount of vibration. There is a rubber component on the engine mount, which can eliminate the resonance generated when the engine is working. Some engine mounts also have the function of hydraulic oil decompression, the main purpose is the same. There are generally three engine mounts in one car, which are fixed on the body frame. If one of them is damaged and not replaced in time, the balance will be destroyed, and the other two will be damaged by acceleration.
The damage to the engine mount mainly affects the vibration of the engine. The high-speed engine noise may be related to the gradual wear and aging of the engine, and it is not particularly related to the broken engine mount using for 1 or 2 years. Sometimes good oil may significantly make the noise of the engine vibration better.
Normally, the engine mount can be used for more than 6 years, and there is no clear replacement cycle, the replacement time should be determined according to the actual situation. When it is found that the engine vibrates obviously and is accompanied by a lot of noise when idling, it is likely that the rubber is faulty. It is necessary to check whether the rubber is aging or broken, if there is, it needs to be replaced as soon as possible.
