For the inspection and maintenance of automobile engine support, the following steps can be taken:

1. Visual inspection: First, you can visually inspect the appearance of the engine support for obvious damage or looseness. Check whether the rubber pad of the support is cracked, deformed or fallen off.

2. Vibration test: Use professional vibration test instruments to test the vibration of the engine. By measuring the amplitude and frequency of vibration, it can be preliminarily judged whether the engine support is faulty.

3. Check the supporting bolts: Check whether the bolts supported by the engine are loose or broken. If the bolt is found loose, it can be retightened. If the bolt breaks, it needs to be replaced with a new bolt.

4. Replace the engine support: If it is confirmed that the engine support is faulty through inspection, a new engine support needs to be replaced. Select the engine support suitable for the vehicle model and engine, and ensure that it is installed correctly.
