just a quick question really for somebody who has actually done this to there a3

im going to flush my coolant system and put sum fresh coolant in tomorrow supposed to be really nice weather, been up to my local tps earlier today and got some coolant going to do it tomorrow afternoon but just wondering whats the easiest way to do this?
Can I leave the belly pan on under the front? is there some type of way I can drain it from the radiator? or do I unclip a hose wait for it all to leak out then reattach the hose fill up coolant tank up with a kettle full of boiling water put the heater on full heat but low blow wait for it to get hot then get back under and unclip the hose and repeat the whole process again until it comes out clear blahdy blahdy blah

thing I don't no guys is whats the best way for me to drain the old coolant out ?? thanks for your responses guys:audibash:
