    Note
    Make sure vehicle is not in Drive, shifting the vehicle into Drive will stop this routine. The test will last approximately 10 mins. The test will vary speeds from 3500-6500 RPM (idle speed = ~1500 RPM) and actuate the valve between series and parallel. If speed hovers at 7000 RPM, it indicates the pump is air locked, perform the vacuum fill again. Continue to add coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  12. Install the HEPA filter assembly. See SERVICE KIT - HEPA AND CARBON FILTERS (Remove and Replace).
  13. Remove the vehicle from the 2 post lift. See Raise Vehicle - 2 Stands.
