⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow engine to cool before opening radiator or inspecting components to prevent burns.

Symptoms

•Burning smell noticeable inside or outside the vehicle
•Possible smoke emanating from the engine bay or undercarriage
•Warning lights illuminated on the dashboard (e.g., temperature or oil pressure)
•Engine overheating or fluctuating temperature gauge
•Reduced engine performance or strange noises

Diagnostic Steps

1
Inspect the engine bay visually for signs of burnt oil, leaking fluids, or damaged wiring.
2
Check the coolant level and inspect for leaks in the cooling system.
