Thats a great writeup, thanks cn90! I need to check receipts from previous owner, I think the hoses, reservoir, Tstat, were done in 2010-2011 by previous owner. Possibly water pump too.

I did both belts, both tensioners, idler pulley, and fan clutch in 2012 after I bought the X5. Probably am due for coolant drain/fill, however.
