Curious on E90 N54 Engine Coolant Change

A little over 2 gallons is the capacity...So buy 3 gallons. Mix 50/50 with distilled water only, not tap water.

so if i buy 2 gallon mix with 50/50 water then wouldn't it be enough since it'll be 4 gallon?

8.2 liters if MT
8.4 liters if AT

i asked around few vendors they all said 1 gallon is more than enough for drain and fill so that's that i guess..

Any tips from the people have done this? Any write-ups? Where can I find info about the bleeding procedure and the mixture ratio?

Thanks

Piece together the answers that are already in this thread plus a little search for ENINTY's N52 coolant change DIY, and you will have your answers.
