Anti-freeze/coolant question (green, orange or pink)

[duandcc_forums at cox.net]

I'm not sure if you can mix G12 (pink) and DexCool (orage), but from what I've seen as long as you do a good flushing, you can run either in your Audi. I've been using DexCool for many years in my various Audis (4000 5+5, 90q & CGT). Never had a cooling system failure...
