⚠️ Safety Warnings

Important safety information - read before proceeding

•Allow engine to cool before opening the hood.
•Disconnect the battery before working on electrical systems.

Symptoms

•Strong burning odor from the engine compartment
•Smoke visible from the engine or undercarriage
•Overheating engine temperature gauge
•Warning lights illuminated on the dashboard
•Decreased engine performance or power loss

Diagnostic Steps

1
Inspect Engine Bay: Open the hood and visually inspect for any obvious signs of leaks, burnt wires, or damaged components.
2
Check Fluid Levels: Verify oil, coolant, and transmission fluid levels; low levels could indicate leaks or burning fluids.
3
Scan for Error Codes: Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to engine performance or electrical systems.
4
Inspect for Leaks: Look for fluid leaks under the vehicle and around the engine, focusing on oil, coolant, and transmission fluid.
5
Monitor Temperature: Use an infrared thermometer to check engine temperature and identify any overheating areas.
6
Examine Electrical Components: Inspect wiring harnesses and connectors for signs of melting or damage.

Solution
