    Do not clean using brake cleaner or other reactive solvents as these solvents can damage rubber gaskets, seals and bushings.

  1. Thoroughly clean the suspected leak area using a rag.

    Do not idle vehicle, this will not actuate transmission systems, and do not drive the vehicle on the freeway as this will splatter oil inhibiting leak diagnosis.

  5. Shut OFF the engine.
  6. Inspect the suspected leak area.
  7. Trace the leak path through the powder in order to find the source of the leak.
