Easy Coolant Question

When I open my radiator drain plug / drop the lower hose, how many gallons of coolant can I expect to come out before it stops?

Found it... 3-4 gallons... Was buried 5-6 pages deep into the coolant change tech thread!

I added a fumoto valve to each side of the 6.0 engine. This made the coolant flush much easier as I drained over 5 gallons each time I flushed. I can open these valves when the engine is hot. Big time saver!

I don't have the fumoto valves on my other Ford van and I drained only 3 1/2 gallons from the radiator pet ****.
