E70 4.8l V8 Coolant Drain Point location (Engine block).
 

I have a 07 4.8l V8 E70 N62 engine. I am wondering if anyone would know the location of the engine block drain point for the coolant.
I have located the radiator drain point but I can only get 5 litres out of the car from here. The rest is in the engine block. Coolant pump is mechanical not electronic. I replaced the upper hose from the Radiator to the pump (leaking o-ring). I don't want to start disconnecting everything either to drain. If someone can tell me or show me where the plug is located.

Many Thanks

Not sure it is all in the block. Heater core, hoses, etc.

I have been draining my system multiples times over the past week. Max I can get is 7 liters plus whatever was under the valley pan. Not easy to drain it all. Use distilled to flush it. I've gone through 10 gallons of distilled to flush.

Thanks guys. Yes I have flushed and cycled the engine a few times now. I think I will have to dissemble more hoses to drain it all. Have to say it's a bad design for an engine. BMW must have purposely designed it like this. The hoses around the engine are easy to install, (Quick connect type), but not service of coolant, No, this needs special equipment and procedures. Haha. [emoji3515]
