Coolant change question

[Gamb1t]

Hi All,
Just wondering is the coolant drain the same as an e90 which is to remove the radiator cap or do I have to unhook the lower rad hose and let it Niagara Falls down into a pail?

Just need to do a simple drain and fill as opposed to a full flush.

They actually have the same radiator as an E90, in the n55 model. There is a small drain plug underneath and just pop the coolant cap and it should drain out from the plug, unless it somehow gets clogged.

Great! thanks for confirming that. I guess I still have to remove that undertray. Wished it has a hole to accommodate this.
