  6. On 3.9L engine, add as much coolant as possible to the engine fill. The heater air bleed will remain open. Install engine coolant fill cap.
  7. On all engines, start engine and set heater controls to MAX heat position. Close heater air bleed when a steady stream of coolant comes from bleed during idle. Allow engine to idle for 5 minutes. Add coolant as necessary to maintain cold fill MAX mark on degas bottle.
  8. Reopen the heater air bleed to release any entrapped air and close again.

Recheck to ensure hot air is still coming from heater. Set temperature control to 75°F (24°C) and allow engine to idle for 2 minutes. Shut engine off, and allow to cool.
