Flushing the Eiswolf 2 AIO

[Random_Person38]

Is there a proper (and easy) way to flush the AIO and an effective way to fill it back up? I'd like to replace the coolant with a coloured one when my AIO arrives. I'm a beginner at water-cooling and don't know much.

You can drain the water by opening the port on the back of the radiator. When doing so, also open the quick-release fasteners and press the inner nipple of one of them so that no negative pressure is created. You can fill the whole thing again via the rear port on the radiator. But, when using fabiger liquid the warranty is void. Colored liquids always cause discoloration on the radiator and can in the worst case stick the pump.
