Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, mechanic's stethoscope, oil catch pan, and replacement oil if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug and allow old oil to drain into the catch pan.
2. Replace the oil filter using an oil filter wrench to ensure a tight seal.
3. Reinstall the oil drain plug and torque it to the manufacturer's specifications (typically around 25-30 ft-lbs).
4. Fill with the recommended engine oil type (typically 0W-20 for this model) to the correct level.

3. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Use a jack to support the engine slightly.
2. Remove the bolts securing the engine mounts using a socket set.
3. Replace any worn or damaged mounts with new ones.
4. Reinstall bolts and torque them to the manufacturer's specifications.

4. Tighten Exhaust Components (if applicable)

Sub-steps:
1. Inspect all exhaust manifold and pipe connections for looseness.
2. Tighten bolts or clamps as necessary to eliminate exhaust leaks.
