    Note
    Wait until coolant pumps stop running (audible noise). Routine Passed will appear, but pumps will run for 10 minutes. If another routine is started during this time, this routine will fail. Make sure the vehicle is not in "Drive". The routine is still running despite the completed message. Test will vary speeds from 3500-6500 RPM and actuate valves between SERIES and PARALLEL. Putting vehicle into "Drive" will stop this routine. If speeds hover at 7000 RPM, this indicates the pumps are air locked - perform a vacuum fill. Continue to add coolant and purge until the coolant level is between the NOM and MAX Lines on the bottle.
  12. Install the coolant bottle cap.
  13. Install the rear underhood apron. See Underhood Trim - Rear Apron Assembly (Remove and Install).
