Same way you would on any LS motor. Fill the system from the top hose, and make sure the rad (and res if you have one) are filled. Warm the truck up, and turn your heater on high if you have one.
I usually give the upper and low hoses a few squeezes each just incase there was a pocket or kink, but wait until the tstat has clicked and that coolant is in the whole system. Usually you should see the levels in the radiator (and/or res) go down and you'll need to add coolant. Once you see bubbles in the radiator stop and the level seems to stay stable, I give each hose another squeeze or two and check that the levels are full, before capping off the system.
I've even jacked a car up and down a few times if I was REALLY worried about it. Rarely if ever "needed", but gives you an odd satisfaction. I've only done that one trouble-prone vehicles.
