Hi Everyone,

Does anyone know why I have this foamy brown stuff in my radiator? Please see attached pics. After getting a low coolant light, the next day I check my coolant and i found this crap. I decided to do a complete flush, so I drained the system completely, all the way to the engine block. Flushed a couple of times with a garden hose, then i added BMW coolant and distilled water. I ran for a couple of miles and recheck, and I still got this brownish foamy stuff. Any ideas??
