Doing my first diy to drain and refill the coolant on my 2017 430 (F36 with B46 engine). The car has a low temp coolant reservoir and high temp coolant reservoir (new for me, all my other bmws just have one). Is it as simple as opening up a hose at the bottom (thinking water pump), refilling both reservoirs and running the bleeding procedure? or is there more to it? just making sure I don't miss something…

thanks in advance for any help.

I could be wrong but I think one reservoir is for the engine and the second one is for the charge air cooler.
