You can put a flush kit in and barely crack the cap, this makes it easier to get the air out, plus you can usually stretch the heater hose up enough to be the highest point in the system. I agree take the thermostat out till you get the problem fixed it will help in getting air out also, since an air pocket near the thermostat may make it not open properly. While the fan is blowing the right direction, are the fan blades facing the right direction to maximize flow? A good aftermarket fan will allow you to flip the blades over between push and pull. It's not as easy as just reversing the wires.
