Remove all water from the block

Pull the bottom radiator hose off,
Take the drains out of both sides of the block.
Take the heater hoses off and blow air thru them.
Put everything together and mix more antifreeze to distilled water like 70% antifreeze, 30% water.
You are trying to save what $2.00 worth of water????

Um, no. You don't want to go beyond 50% Anti-freeze as glycol isn't as good a coolant as straight water. Thus, you could introduce a cooling problem by using a 70% mixture. Maybe, if you live in ND, WY, or some other place where it gets really, really, really cold, you might want over 50% mixture.

As far as pulling block plugs, heater hoses and using compressed air, I'd skip all of that. I'd pull the lower ratiator hose and drain the radiator and most of the block. Fill as much as possible with straight coolant. Test the coolant. If you don't get to the number you want, open the petcock, drain out another gallon of MIXED coolant and add a gallon of pure coolant. A lot less work than pulling plugs that may be frozen.
