if repetitive flushing is required, do I add AS105 each time?

I add the stuff, drive around for a day, flush the motor out good with clean water a couple of times until water looks clean, and then do the entire procedure over. I use another dose of Flush, then drive for a day, then water a couple of times until clear. In my case I was surprised by the "extra" crud the second flush removed.

What is the mix ratio?

One 22 oz bottle for up to 12 quarts (3 gal) of water. It won't hurt if your total capacity is less than 12 qts, use more if over 12 qts. You can leave it in the system for whatever time is necessary to get the results desired. Does not seem to harm any component of the cooling system. Lime deposits are usually what is clogging the radiator, and they are the most difficult to clean out, that could take repeated treatments. This comes from using tap water to dilute the antifreeze. Only use distilled water, including when mixing with the Prestone flush. RC

I did not see in the directions were it says to drive around. Am I missing something or is this from another version of the cleaner?

Standard flush no, there are two sets of instructions, for severe buildup or somthing it says to leave in in a couple days, make sure your careful not to let it freeze if you do so. It does take quite a bit to get all this out, my cooling system is 1.8 gallons and this whole bottle went in and I had it heat cycle twice with it cooling down over 100 F. Seemed to help get rid of any film I would get on my rad cap

Will this dissolve blue devil stop leak? 2001 corolla

Depends on the size of the leak. Make sure it is not one of the hoses. Small core leaks works fine.. Drain off some fluid off so you can use the entire contents .
