Sounds like a strange question, but what color is it? I am wondering if it could be that you have a slight leak at the head gasket and on the compression stroke you are pushing carbon into the coolant? Are you loosing coolant and/or every notice a light exhaust smoke which would indicate a leak in the head gasket?
Otherwise, maybe someone put a stop leak product in the radiator at one time or another.
