 Is the Dex-Cool green? Any quesses?
 
 So my conclusion is it is probably more important to get all the old green coolant out than what I put in afterward. The problem seems more to be mixing coolant types than what brand you put in. (Havoline, Chevon and Zerex all market Dex-Cool.)

There's no standard on the color.  Porsche's branded coolant was pink at one time and yellow at another.  Don't go by color.
