Can you get the owner's manuals for your vehicle? I pump the pink food-safe antifreeze throughout all of my water lines. I open the farthest away faucets first - run those til the pink fluid appears and shut them off - and then move closer to the pump to the closer faucets. Eventually, all plain water is purged.
I also have the luxury of living at a location where I can safely thin down my antifreeze - I don't need -30 F protection.
