Allow the engine to cool down if it has been running.

2. Inspect and Repair Exhaust System

Tools Required: Wrench set, exhaust pipe cutter (if needed), muffler clamp tool.
Inspect the exhaust system for any signs of rust, holes, or loose connections.
If a leak is found, use the exhaust pipe cutter to remove the damaged section.
Replace with a new section of pipe or muffler as necessary.
Secure the new components with clamps and ensure all connections are tight.

3. Check Engine Components

Tools Required: Socket set, torque wrench.
Inspect engine mounts for wear or damage; replace if necessary.
Tighten any loose bolts or components found during the visual inspection.
Check and replace any worn belts or pulleys.
