 Things I always do when replacing the coolant in a vehicle:

1) Open the heater full bore so there's no air pockets there (not necessarily relevant in the JH unless your vin is in the 17500+ range and you have the vacuum switch and it works).

2) Let it idle up to temperature with radiator cap open. There's almost always an air pocket behind the thermostat. Generally you can see an obvious volume drop in the top of the radiator when the t-stat opens. Then do final top off.
