When I did my coolant flush/water pump/160F thermostat job last spring, I drained the front of the system by lowering the back of the vehicle off the jack-stands so gravity could drain it out the two large hoses you disconnect at the engine.
I got out 19 of the alleged 20 litres of coolant this way.
Close enough for me.
I know my car had Porsche coolant in it originally, so I didn't lose my mind by leaving a bit of old stuff in the system.
