changed lower rad hose and put 4 gallons anti freeze, now doesn't seem to be circulating
is there an easy way to get air out ???
 
Pull the upper hoses and fill until water begins to come out of the thermostat housings. Install the upper hoses and continue filling to within 2 inches of the radiator filler neck. Run the engine and observe when the thermostats open. You should see activity at that point.
