    Note
    • Make sure that the vehicle is not in Drive. Putting the vehicle into Drive will stop this routine.
    • The pumps will still run for some time after the Routine Passed message displays. Do not start another routine before the coolant pumps stop running.
    • 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.
  14. Inspect the coolant level and top off as necessary, make sure that the fluid level is at the MAX line, and then install the coolant bottle cap.
  15. Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  16. Install the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  17. Raise the LH front window and close the LH front door.
  18. Remove the lift arms from below the vehicle.
