WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

Perform the following steps in order to diagnose the leak:

  1. Clean the suspected area.
  2. Apply an aerosol-type powder (such as foot powder) to the suspected area.
  3. Operate the vehicle under normal operating conditions.
  4. Visually inspect the suspected component.

    Trace the leak path over the white powder surface to the source.
