Currently I am going to drain the radiator, drain the block (does this plug have a washer that needs replacing?), refill with the shout mix (how much water?). Idle for 10 minutes, drain and flush until it is not soapy anymore.
Then I am going to mix 2.2 lbs of citric acid with warm water (how much warm water?) and pour it in the expansion tank? Should I fill the radiator with water too?
Then Im going to drive for 60 miles, drain the block and radiator, pull all of my hoses and flush with a garden hose. Fill with distilled water and drive and flush 3 times.
Then I will fill with a 50/50 coolant mix, burp the system by parking on a incline, opening the overflow cap and turning on the heat while idling for how long?
This all sound good? Really the only thing I am not clear on is how much water to put into the system, I dont want to put too little in...
Thanks!!

Just mix with warm water in a gallon bucket add to system and continue adding warm water until system is full.IMHO, I am not so sure I would drive 60 miles on a citric acid mix with an unknown system. I ran my car for 15 minutes max and then drained, rinsed etc. Better safe than sorry as many on this site have reported problems after aggressive treatment - both my diesels were treated this way with no problems, but again, I was being very conservative -too much too long can dissolve weak metals, careful -
