      Informational PurposesAn informational icon, calling your attention
      Note
      • The routine will last for a while after the stop message displays. The coolant pumps are audible.
      • The test lasts for approximately 10 mins. Do not start another routine during this time.
      • Make sure that the vehicle is not in Drive. Putting the vehicle into Drive will stop this routine.
      • The speed in the test varies from 3500-6500 RPM (idle speed = ~1500 RPM) and the actuated valve varies between SERIES and PARALLEL.
      • If the speed hovers at 7000 RPM, it indicates the pumps are air locked. Perform the vacuum fill again. Continue to add the coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  11. Inspect the coolant level, top off as necessary, and then install the coolant bottle cap.
