Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical hazards.

Inspect all fluid lines: Look for cracks or damage on coolant hoses, fuel lines, and oil lines.
Repair or replace damaged hoses: Cut away the damaged section and replace it with a new hose or tighten clamps as necessary.
Check for fuel leaks: If fuel is leaking, replace the affected component (e.g., fuel injector, fuel line) immediately.

3. Clean and Replace Contaminated Components

Cabin Air Filter: Remove the cabin air filter and inspect for any chemicals or strong odors. Replace if necessary.
Coolant System: If the coolant is contaminated, flush the system using a coolant flush solution and refill with proper coolant mixture.
