Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Address Diagnostic Codes

Use the OBD-II scanner to retrieve and note down diagnostic trouble codes (DTCs).
Research the codes to understand potential issues related to the noise and check engine light.

3. Inspect and Replace Components

Engine Oil:
- Check the oil level using the dipstick.
- If low, add the correct oil type as specified in the owner's manual.
- If oil is dirty or sludgy, perform an oil change.
Belts and Pulleys:
- Inspect serpentine belts for wear and tear.
- If frayed or cracked, replace the serpentine belt using a socket set.
Engine Mounts:
- Check for damaged or worn engine mounts that could cause noise.
- Replace mounts if necessary by removing the bolts and lifting the engine slightly with a jack.

4. Exhaust System Inspection

Visually inspect the exhaust for cracks, holes, or loose connections that could cause noise.
Tighten any loose bolts or replace damaged sections of the exhaust using a pipe cutter and exhaust clamps.

5. Reconnect Battery and Clear Codes

Reconnect the battery.
Clear any diagnostic codes using the OBD-II scanner.
Start the engine and listen for any persistent noise.
