Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight, jack and jack stands.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery before starting any repairs to avoid electrical shorts.

2. Inspect and Repair Exhaust System

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect the exhaust pipes, muffler, and catalytic converter for any signs of cracks or holes.
If a leak is found, use a pipe repair clamp or replace the damaged section of the exhaust. Ensure all joints are properly tightened.

3. Check and Replace Engine Mounts

Inspect the engine mounts for any signs of wear or cracks.
If damaged, use a socket set to remove the bolts securing the engine mounts.
Replace with new engine mounts and torque the bolts to the manufacturer's specifications.

4. Address Drive Belt Issues

Check the drive belt for cracks or fraying.
If damaged, remove the belt by loosening the tensioner using a wrench.
Replace with a new belt and ensure it is properly aligned on the pulleys.

5. Reassemble and Reconnect

Reconnect the battery terminals.
Lower the vehicle from the jack stands.
Start the engine and check for any remaining noise or issues.
