Disconnect the battery to ensure safety.
Allow the vehicle to cool down before starting work.

2. Inspect and Repair Exhaust System

Inspect for Leaks:
- Visually check the exhaust pipes, muffler, and connections for any signs of rust, cracks, or holes.
Repair or Replace:
- If leaks are found, use exhaust tape for minor repairs or replace damaged sections with OEM parts.
Reattach Components:
- Ensure all hangers and clamps are securely fastened.

3. Engine Mount Inspection and Replacement

Remove Engine Cover (if applicable):
