Just a comment regarding the proper solution procedure. If the cooling system is flushed with a kit and water, disconnecting the bottom radiator hose will not drain all the water. At least that has been my experience with other cars. I usually found out what the system capacity is, calculated what 60% of that is, and poured that amount of antifreeze into it. After connecting all the hoses that is.
I then topped off with water and added 60% mixture to the reservoir.
