Any car I have ever worked on (mostly my old Cavalier and my sister's Dodge, etc.) have all had green. So you are saying do a full drain with distilled water, and then only add water again? I'm just worried about getting the right mix. I was thinking drain, run water, drain, and then filling with an even mix of the green stuff and water.

P.S. I have heard if you drain and then just top off with green it should be okay as you will eventually work off the orange with regular changes, but it sounds sketch.

Can I just drain and then top off with the green, hoping there will be little orange left? Which will eventually work itself out? Or should I flush completely in order introduce all green into the engine?
