Coolant flush

Hello I have a 07 Silverado and mistakenly mixed Dexcool with the green coolant. Does anyone have suggestions on doing a complete flush? Thank you

Run til hot and pull lower rad hose. Replace fill with water. Repeat three times This time fill with 100% of coolant you want to use. It'll be close to 50/50.

Not knowing which "green stuff" we are talking about, I have to ask: Does the bottle that the green stuff comes in say it is compatible with Dexcool?
