Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, jack, and jack stands.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Engine Mount Inspection

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the engine mounts for any signs of wear or damage.
If mounts are cracked or deteriorated, remove the bolts securing the mount to the engine and the chassis using a socket set.
Replace with new engine mounts and torque the bolts to the manufacturer's specifications.

3. Exhaust System Check

Inspect the exhaust system, focusing on connections and hangers.
Tighten any loose bolts or clamps using a socket set.
If any heat shields are loose or damaged, replace them or reattach securely with the appropriate fasteners.

4. Drive Belt and Pulley Inspection

Remove the drive belt using a wrench to relieve tension on the belt tensioner.
Inspect all pulleys for wear or misalignment; replace any defective components.
Reinstall the drive belt, ensuring proper routing and tension according to the manufacturer's specifications.
