why does my Honda Pilot YF3 (2016-2022) have a weird smell coming from the engine?

Solution

1. Preparation

• Tools Required: Safety gloves, safety goggles, OBD-II scanner, flashlight, rags for cleaning.
• Ensure the engine is cool before starting any work. Disconnect the battery if necessary.

2. Addressing Fluid Leaks

• Locate and Repair Leaks:
  1. Identify the source of any fluid leaks observed during the visual inspection.
  2. If oil is leaking, replace the oil filter and gasket if necessary, or tighten any loose connections.
  3. For coolant leaks, inspect hoses and replace any damaged ones. Refill the coolant reservoir with the appropriate type of coolant.

3. Clean and Replace Components

• Clean Oil or Debris:
  1. Use rags to wipe away any oil or debris from the engine components.
  2. If there is any burnt rubber or plastic smell, inspect and replace any frayed or damaged belts and hoses.

4. Exhaust System Check

• Inspect and Repair Exhaust:
  1. Check the exhaust system for any holes or rust that could cause exhaust fumes to leak into the engine bay.
  2. Replace any damaged sections of the exhaust as needed.

5. Final Checks

• Reassemble and Test:
  1. Reconnect the battery if it was disconnected.
  2. Start the engine and observe for any unusual smells or sounds.
  3. Allow the engine to reach operating temperature and monitor for leaks or odors.
