I just flushed mine and used Prestone Dexcool. You do not need to go with ACDelco. Prestone or Zerex (Vavloline) are perfectly fine. I believe Peak makes a Dexcool too. Pick em up at either Amazon or Walmart, cheapest I found. And I went with the pure coolant, not the 50/50 mix. You need about 1.5 gallons to fill your system, so buy 1 non-mixed jug and 2 distilled water jugs and mix them.
