Air could be trapped in the system. When you feel the lower radiator hose, it should feel like the coolant in it is surging from the waterpump pumping. Also feel the two hoses going in the firewall to the heater core. Both should be hot. If one is not, then heater core is either plugged or has trapped air. What I would do is this...
-Fill the system up, when cold
-Park the vehicle or raise the front end as high as you safely can
-run vehicle w/radiator cap off (heater fan on high) until thermostat opens
-once the thermostat opens, fill as needed, insert radiator cap
-run a little longer to build the pressure up and try bleeding at screw
-let vehicle cool down and check level again
keep doing this until the air is bled out. Some vehicles are harder than others to bleed and may take a few times to fully get it.
