Hah! I am so glad to hear you say it, or read it, almost as good.
I want to do the smart thing but I don’t want to be an idiot about it. And jumping through hoops to thoroughly flush the green at this time is just not some thing I am well prepared for. Plus, if I do it, I want to know the best procedure. One can read plenty of horror stories of people who are unable to flush their cooling system as well as they wanted. I know it’s always been tricky for me.
I should find more info about mixing gold and green. Not that I want to do it, I just want to know what’s up with it and how important it is to avoid it, etc.
