Orange or "dexcool" is the WORST thing you can do to any cooling system. It is acid. It will lead to premature failure. Ask any GM guy with a 3.1, 3.4 or 3.8 and dexcool. LOTs and lots of failures. IT also is ENTIRELY incompatible with any form of green coolant. Google "dexcool" and see for yourself.
