Safety Warnings: Ensure the engine is off and cool before beginning any work. Disconnect the battery to prevent electrical shorts.

2. Address Loose Components

Sub-steps:
1. Tighten any loose bolts or fasteners found during the inspection of engine components.
2. Replace any worn or damaged belts if they are contributing to noise.
3. Reassemble any removed components and ensure all connections are secure.
