why does my Toyota Corolla E140 (2006-2013) have a weird smell after driving?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Clean Engine Components

• Sub-steps:
  • Open the hood and visually inspect the engine for oil or coolant leaks.
  • If oil is leaking, clean the affected area and replace gaskets or seals as necessary.
  • For coolant leaks, check hoses and connections for wear; replace any damaged components.

3. Check and Replace Cabin Air Filter

• Sub-steps:
  • Locate the cabin air filter (usually behind the glove compartment).
  • Remove the glove compartment if necessary to access the filter.
  • Replace the cabin air filter with a new, high-quality filter to reduce odors.

4. Inspect Exhaust System

• Sub-steps:
  • Examine the exhaust manifold, catalytic converter, and muffler for signs of damage or leaks.
  • Tighten any loose connections and replace any corroded or damaged components.

5. Clean and Maintain Air Conditioning System

• Sub-steps:
  • Use an air conditioning cleaner spray into the air intake while the system is running to eliminate odors.
  • Consider using a professional-grade cleaning service for deeper cleaning of the evaporator core if necessary.
