I am assuming that you had your heater set to full heat when you were trying to purge your system of air. If not than air, could still be trapped in your heating system.

Also, if you set your heater controls to full heat, do you get hot air out of the ducts? When your engine is at operating temperature, and depending on your ambient temperature at the time, the air temperature coming out of the ducts should be somewhere between 100F - 125F (approximately).
