Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, engine oil, engine mount inspection tool (if necessary)
Verify that the vehicle is parked on a level surface and ensure the engine is cool before starting any work.

2. Address Engine Oil Level

Sub-steps:
- Open the hood and locate the dipstick.
- Remove the dipstick, wipe it clean, and reinsert it.
- Check the oil level; if low, add the recommended oil type (consult the owner’s manual for specifications).
- If oil is contaminated, proceed to change the oil and filter.

3. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
- Remove any components obstructing access to the engine mounts (such as covers or brackets).
- Use a socket set to remove the bolts securing the engine mounts.
- Inspect the mounts for cracks or excessive wear.
- Replace with OEM or quality aftermarket mounts.
- Reinstall bolts to the manufacturer’s torque specifications.

4. Inspect Other Engine Components

Sub-steps:
- Check all belts and pulleys for wear and proper tension.
- Tighten any loose components and replace any worn parts as necessary.
- Ensure all accessories (such as alternator and power steering pump) are functioning correctly.
