Remove the hoses (some people don't) because it allows you to properly seat the new gasket. Draining the coolant is a simple task with the N52/54/55 since the refill and bleeding procedure is done cold with the electric water pump.

Appreciated.
I am still having difficulty releasing the 3 Torx E10 screws and I am starting to order proper E10 socket and wrench. So far I have found out that using a 8mm socket/wrench is a very bad idea, at least for me.
I will probably post some additional photo and information to enhence this helpful DIY.
