Robert, do not mix orange coolant with traditional green coolant, regardless of what the bottle says. GM Engineering ran tests on mixing them with poor results. As a side note, I would recommend sticking with green coolant. It is what your system was designed for. In addition, when orange coolant gets too hot it has a tendancy to gel, which plugs water passages and fries water pumps. A well-maintained car should never overheat, but things happen and I would not want that in my cooling system if I ran hot for some reason.
