Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, stethoscope or mechanic's listening tool
Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool before inspection.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil filler cap and dipstick; check oil level.
2. If oil is low or dirty, drain old oil using an oil pan and replace it with new oil (use manufacturer's recommended oil type and viscosity).
3. Replace the oil filter if necessary using an oil filter wrench.

3. Inspect and Replace Engine Mounts

Sub-steps:
1. Use a jack to slightly lift the engine for better access to engine mounts.
2. Visually inspect engine mounts for cracks, tears, or excessive wear.
3. If any mounts are damaged, remove the bolts securing them using a socket set and replace with new mounts, following torque specifications (typically around 40-50 Nm, check specific model requirements).

4. Examine and Replace Serpentine Belt

Sub-steps:
1. Loosen the tensioner using a wrench to relieve tension on the serpentine belt.
2. Remove the old belt from the pulleys, noting the routing.
3. Install the new serpentine belt following the routing diagram usually found on a sticker in the engine bay.

5. Inspect Exhaust System

Sub-steps:
1. Visually inspect the exhaust system for any cracks, holes, or loose connections.
2. Tighten any loose bolts or clamps using a socket set.
3. Replace any damaged sections of the exhaust pipe or muffler.
