What are the symptoms of engine mount failure?

[ChloeFitz]

Engine mount failure symptoms: The car makes abnormal noises during starting, climbing, or accelerating, and the engine becomes unstable at idle. When these symptoms occur, the engine mounts need to be replaced to provide vibration damping for the engine. The buffer mounts are usually made of pure rubber or rubber products with metal frames. Since the rubber's impact resistance is greater than its dynamic stiffness, it can effectively reduce the car's impact deformation. In ordinary cars, the engine mounts consist of rubber elastic blocks with two separate screws installed above and below. The upper screw is mounted on the engine, and the lower screw is mounted on the frame, relying on the middle rubber block for elastic buffering. High-end vehicle engine mounts also feature controllable hydraulic pressure devices, where the computer adjusts the oil pressure to adapt the elastic hardness to different speeds.
