I have had good success just bleeding the coolant manually. Follow the procedure in the pelican tech article, then, with the purge bail in the upright position, drive to a multi story parking lot that has steep ramps. Point the nose of the car down the ramp, stop the car and rev the motor a bit so any air in the radiators naturally moves out of the radiators.

Check the coolant level and top up.
