⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems
•Allow the engine to cool before opening the radiator or working on fluid systems

Symptoms

•Visible fluid pooling under the vehicle
•Unusual fluid color (e.g., red for transmission fluid, green for coolant)
•Unpleasant odors (e.g., burning smell from oil)
•Decreased fluid levels in the reservoirs
•Warning lights on the dashboard (e.g., low oil pressure)

Diagnostic Steps

1
Inspect the ground under the vehicle to determine the type of fluid leaking (color and consistency)
2
Check fluid levels in the engine oil, transmission, coolant, brake fluid, and power steering fluid reservoirs
3
Examine hoses and connections for signs of wear or damage, particularly around the areas of the leak
4
Inspect the engine bay for any visible leaks or wet spots on engine components
5
Conduct a dye test if necessary, adding dye to the suspect fluid to trace the source of the leak
6
Look for signs of corrosion or damage on components associated with the fluid systems
