What cooling hoses to order

[Dorito]

Yo! Going through the process of renewing everything under the hood of my 99 2.8

I am onto ordering parts for the cooling system I have the stuff that I am accustomed to ordering for other BMWs (radiator, expansion tank, thermostat, water pump, rad hoses etc.) but I am not used to having and expansion tank that is separate from the radiator.

i am aware of the expansion tank hose that runs from the top of the radiator to the top of the expansion tank but I am unfamiliar with the ones that connect to the bottom.

How many other hoses are there down there? And are they considered cooling system parts Or heating system?
