Then someone cranks the engine (preferably with spark plugs disconnected) while you pour fresh fluid into the funnel that is inserted into the hose. The res will fill up through the system, then you drain the res by taking the lil piece of foil off. Do that 2x and you have a really clean fill of fluid. We call just sucking the reservior fluid out the "turkey baster" method. You could draw out fluid all day that way and still not get it as clean as a proper flush that takes 5 minutes. Since you are changing fluid type, I recommend the way I described even moreso.
