Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery for safety.
2. Inspect and Replace Cabin Air Filter
  • Remove the glove compartment to access the cabin air filter housing.
  • Take out the old cabin air filter and inspect for dirt and mold.
  • Replace with a new cabin air filter (ensure proper orientation).
  • Reassemble the glove compartment.
3. Check for Coolant Leaks
  • Inspect all coolant hoses and connections for signs of wear or leaks.
  • If leaks are found, replace damaged hoses and re-tighten connections.
  • Top up the coolant level if necessary, using the specified coolant type.
4. Examine Engine Components
  • Inspect the engine bay for any burning smells related to electrical components or fluids.
  • Check the condition of the serpentine belt; replace if cracked or worn.
  • Look for signs of leaking oil or other fluids that may cause odors.
5. Evaluate the Air Conditioning System
  • Inspect the A/C evaporator for mold or mildew buildup.
  • If mold is present, consider using an A/C cleaner specifically designed to eliminate odors.
  • Replace the A/C expansion valve if it’s malfunctioning and causing refrigerant leaks.
