I drained /filled the coolant a couple weekends ago. In order to minimize the time and mess, I only drained the radiator and the lower radiator hose. Not too difficult to remove the air dam and get to the radiator stopcock, and remove the airbox to remove the lower radiator hose. Since there was no rust or particulates in the old coolant I decided not to flush the system. I got out almost 8 qts which was satisfactory, and minimal spillage.
