I was replace the coolant hoses on my 87 325is and when i drained the coolant out it was black. I did some research on it and supposedly its from high concentrations of metal. The car runs fine and according to the coolant temp gauge it runs at normal temperature. No over heating
Has this happened to anyone is it a serious problem? What should i do besides wash it all out?
