Solution

1. Preparation

Tools Required: OBD-II scanner, stethoscope, socket set, torque wrench, jack and jack stands.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the engine is cool before starting.

2. Address Engine Mounts

Raise the Vehicle: Using a jack and secure it with jack stands.
Remove Engine Mount Bolts: Use a socket set to unbolt the engine mount from the chassis and engine block.
Install New Mounts: Position new engine mounts and tighten to manufacturer specifications (typically 45-60 Nm).
Lower the Vehicle: Remove jack stands and lower the vehicle.

3. Replace Worn Belts and Pulleys

Inspect Belts: Check for fraying or cracks; replace if necessary.
Remove Tensioner: Use a socket to relieve tension and remove the serpentine belt.
Install New Belt and Tensioner: Replace with new components, ensuring proper alignment.
Check Alignment: Spin pulleys by hand to ensure they are operating smoothly.

4. Repair Exhaust System

Inspect for Leaks: Visually inspect the exhaust for holes or loose connections.
Seal Leaks: Use exhaust sealant or replace gaskets as needed.
Tighten Loose Components: Use a socket set to secure any loose bolts on the exhaust hangers.

5. Oil Change (if necessary)

Drain Old Oil: Remove the oil drain plug and allow oil to fully drain into a pan.
Replace Oil Filter: Use an oil filter wrench to remove the old filter and install a new one.
Add New Oil: Replace the drain plug and fill the engine with new oil, ensuring the correct type and amount (typically 5W-30 for the XC60).
Check for Leaks: Start the engine and monitor for any leaks around the oil filter and drain plug.
