Sounds like an "automatic" drain mechanism is in place. Where should I put a container for old coolant?
E60 has life time coolant fill according to BMW TIS (2005 version).

Does anyone have better info on this? why would you be using a battery charger? I'm trying to understand the entire process here... It helps me to understand exactly what is happening and why?
I just got a low radiator fluid warning and figured i'd do a change since the car has just under 50k miles and i doubt its been changed ever...

What has charging the battery got to do with changing coolant? ALSO, #2 "switch on ignition", #4 "depress accelerator pedal to the floor, ENGINE MUST NOT BE STARTED" 
? PLEASE fill me in.

I believe it's because these cars have an electric coolant pump (not engine-driven), so to bleed the system, the coolant pump has to be activated by turning the key "on" and pressing the pedal. I think the battery charger is just so you don't kill your battery while doing this procedure.

Also, are you saying that the water pump is NOT belt driven? that is a first for me!
