Steps from the factory service manual for refilling and bleeding the cooling system:
CAUTION:
Turn the pressure cap clockwise until clicks are heard. Failure to tighten the pressure relief cap may result in engine damage.

1. Fill the radiator through the degas bottle. Install the pressure relief cap when full.

2. Fill the degas bottle until the coolant level is at the COLD FILL range mark.

3. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air from the A/C vents to the instrument panel.

4. CAUTION:
If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow it to cool and fill the cooling system.

Run the engine until it reaches operating temperature.

5. WARNING:
To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in personal injury.

Turn off the engine and allow the cooling system to cool. When the pressure has been released, remove the pressure relief cap. Add more coolant mixture to the degas bottle until full.

6. Add more coolant mixture to the degas bottle until the coolant level is at the COLD FILL range mark.

7. Start the engine and allow it to idle. While the engine is idling, feel for hot air from the A/C vents.
Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.

8. Check the engine coolant level in the degas bottle and fill it as necessary.

9. Repeat Steps 5 through 8 as necessary.
