2004 Corolla - Draining Water

[corolla runx]

hi there everyone

thanks for an awesome forum and i am new here

just a quick question

my mom asked me to drain the water and replace with antifreeze and now i need to know if you just remove the bottom radiator hose to drain and refill with antifreeze and water. i know on some models you'll have a drain plug on radiator to drain and to bleed to system you'll have a bleeder valve. i just need to know the procedure on a 2004 model 140i the runx shape

thanks in advance
