I replaced my water pump this weekend due to it seizing up and breaking off all the belts. When I drained out the coolant from the radiator, it was black. That bothered me so I drained the whole system from the engine block and yet again the coolant was still black. I know it is supposed to be blue if you use BMW coolant, which I do, but I had just changed the coolant this summer.

Could the black coolant possibly be from the water pump going out?
Just sorta worried about going on an upcoming 700 mile adventure.
