By now you've likely worked out all the air. Is the expansion tank staying full? As the system cools down it will draw from that tank.
How's the temp gauge reading?
A very common problem is a clogged heater core. You could disconnect both hoses and flush it out with a hose.

The capacity is 13 quarts including the overflow tank.
Here's how to bleed it, from the FSM:
REFILLING 4.7L ENGINE
CAUTION: Failure to follow the procedure outlined
below, can result in engine overheating conditions
and sever damage to engine.
(1) Tighten the radiator draincock and the cylinder
block drain plug(s) (if removed).
(2) Fill system using a 50/50 mixture of ethyleneglycol
antifreeze and low mineral content water.
(3) Fill coolant reservoir to FULL mark.
(4) Install radiator cap and reservoir cap.
(5) Start engine and run at 3000 RPM for 10 seconds.
(6) Shut engine off.
(7) Remove radiator cap.
(8) Fill radiator to full level.
(9) Install the radiator cap.
