I am trying to drain the radiator of the coolant and do a flush but cannot seem to find where to drain from bottom of car. I have taken off the plastic cover on the front just past the front bumper. Is there more that I need to remove? I have watched every video on YouTube and there were not any with the G11/G12. please help.  The photo is for reference so you can see what I am looking at.I

Welcome to the Forum

On the back/engine side of the rad at the bottom on the right side of the car you should find a Tap with a Red screw cap, put a flat head screw driver into the red cap and turn anti clockwise 

You could try looking at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model. It is a parts list but it's exploded drawings are a help when seeing where stuff is. Also look at Pelican parts web site their articles have some great how too's with pictures

Hope this helps
