I get what you're saying. BUT if you're saying that I can't be totally sure that it's empty with draining it and blowing air through it, then wouldn't you also be saying that you can't be sure you're getting YOUR water out by draining it before you try to replace the water with antifreeze? Who's to say that you don't have pockets of water that the antifreeze isn't mixing with?

I mean, come on, it can't work both ways. If you're unsure that all the water is out in my scenario, how could you be sure all the water is out and replaced with antifreeze in yours?
