why does my Volvo XC90 make a strange burning smell

Solution

1. Preparation

• Gather necessary tools and ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect Engine Components

• Check Fluid Levels:
  • Verify engine oil and coolant levels; top off if low.
  • Inspect for leaks around the oil filter and radiator.
• Inspect Belts:
  • Remove the engine cover if necessary.
  • Check the serpentine belt for cracks or signs of burning.
  • Replace the belt if damaged.

3. Brake System Inspection

• Check Brake Components:
  • Remove the wheel to access brake calipers and rotors.
  • Inspect brake pads for wear and overheating; replace if necessary.
  • Check for sticking calipers that may cause excessive heat.

4. Electrical System Check

• Inspect Wiring:
  • Examine the wiring harness for any signs of melting or exposed wires.
  • Repair or replace damaged wiring as needed.

5. Testing

• Reconnect Battery:
  • Reconnect the battery after all inspections and repairs are complete.
• Start Engine:
  • Monitor for any new smells or signs of overheating after repairs.
