That would make a total of 8 + 7 = 15 rubber cooling system hoses in the BMW 2002 525i automatic (assuming no duplicate counts).

Is this count correct?

#6 in this image was the little devil that took me the longest to find. Valve had a crack in plastic and when opened would pump coolant over board but never created puddles as it only opens when hot... And would burn up on motor.
