Solution

1. Preparation

Gather tools and parts required for inspection.
Park the vehicle in a well-ventilated area and ensure it's turned off.
Disconnect the battery to ensure safety during inspection.

2. Check and Replace Cabin Air Filter

Remove the glove box to access the cabin air filter compartment.
Take out the old cabin air filter; inspect for mold or debris.
Install a new cabin air filter, ensuring it is properly seated.
Reassemble the glove box.

3. Inspect and Repair Fluid Leaks

Check for coolant leaks: if present, locate the source (hoses, radiator, water pump).
If coolant is leaking, replace the damaged component and refill the coolant system with the appropriate type (typically a 50/50 mixture of antifreeze and distilled water).
For oil leaks, replace any worn gaskets or seals found during inspection.

4. Repair Exhaust System

Inspect the exhaust pipes and connections for cracks or holes.
Tighten any loose connections or replace damaged sections of the exhaust.
Use an exhaust sealant if necessary to seal minor leaks.

5. Electrical Inspection

Look for burnt wiring or connectors in the engine bay.
Replace any damaged wiring harnesses or connectors.
Ensure all electrical components are functioning properly.
