why does my Toyota Tacoma N300 (2016-Present) have a burning smell coming from the engine?

Solution

1. Preparation

• Tools Required: Gloves, safety goggles, flashlight, lint-free cloth.
• Ensure the engine is cool before starting any inspection.
• Park the vehicle on a flat surface and engage the parking brake.

2. Address Fluid Leaks

• Inspect Fluid Levels:
  • Check engine oil level using the dipstick; add oil if low.
  • Check coolant level in the reservoir; top off with the manufacturer-recommended coolant if necessary.
• Fix Leaks:
  • Identify the source of any leaks (gaskets, seals, hoses) and replace as needed.

3. Electrical Inspection

• Inspect Wiring:
  • Look for damaged or melted wires; repair or replace as necessary.
  • Ensure all electrical connections are secure.

4. Replace Damaged Components

• If leaks are from the oil pan or gaskets:
  • Remove the affected components (e.g., oil filter, gaskets).
  • Clean the surfaces and install new gaskets.
  • Refill oil to the appropriate level.

5. Test and Monitor

• After repairs:
  • Start the engine and monitor for any burning smell or smoke.
  • Check the engine temperature gauge to ensure it operates within normal limits.
