6. Install new engine mounts and torque bolts to manufacturer's specifications.

3. Replace Accessory Components (if applicable)

Tools Required: Socket set, belt tensioner tool.
Sub-steps:
1. Identify the noisy accessory component using the stethoscope.
2. Remove the serpentine belt by releasing tension with the belt tensioner tool.
3. Disconnect and remove the faulty component, taking note of any mounting hardware.
4. Install the new component and reconnect the serpentine belt, ensuring proper routing.
5. Start the engine and check for noise.

4. Repair Exhaust System (if needed)

Tools Required: Wrench set, exhaust pipe cutter, exhaust clamps.
Sub-steps:
1. Inspect the exhaust system for leaks or loose connections.
