On 3.9L engine, open engine coolant fill cap.
On 3.0L engine, open air bleed located in upper radiator hose inlet pipe.
On all engines, open heater air bleed located in left rear corner of engine compartment. Add coolant to degas bottle until no more coolant can be added.
On 3.0L close air bleed on upper radiator hose inlet when coolant begins to escape.
On all engines, install degas bottle cap.
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.
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.
Reopen the heater air bleed to release any entrapped air and close again.
Increase engine speed to 2000 RPM on 3.9L engine, or 1500 RPM on 3.0L engine. Hold for 3-5 minutes, or until hot air comes from heater. Allow engine to idle. 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.
After engine has cooled, add coolant to degas bottle as necessary to bring level to cold fill MAX mark.
