If you have an OEM water pump or a replacement water pump with at least a 4" impeller, refilling the cooling system is a no brainer.
I went out a couple of weeks ago to help a GMCer that blew a heater hose. While I was enroute the owner repaired the leak and obtained 3 gallons of replacement antifreeze. When I got there we filled the radiator and overflow bottle to the correct levels, warmed up the engine with the cap loose, and topped off the radiator. That was it. The heater hoses were hot so the heater was filled, and the owner drove away. I talked to the owner a week or so later and was told that the overflow bottle took less than 1 pint to bring it to the correct level after driving about 1500 miles in three days.
So fill it up, check it once after warmup, and drive it if you have the standard 4" or larger water pump.
