How much distilled water for coolant flush?

[6.0DSLPWR]

I just picked up a jug each of restore and restore plus and 4 jugs of concentrate delo elc coolant tonight to do my coolant flush. All for $90 which i think was a pretty good deal. I just need to get a new thermostat and some distilled water and I will be ready to do my flush. I am going to follow a writeup I found on here and use tap water for all my flushing except for the final flush where I will use distilled water before adding the elc coolant. My question is how much distilled water will I need for the final flushes with distilled water? Thanks

If you use tap for the general flushing, I'd say you'll need no less that 15 gal. Two complete fills with the distilled, and a gal left over for topping off after your 3.5-4.0 gal of ELC concentrate.

It took me about 23 or so before I got a ph of 7.

I'm subscribing to see if your results turn out like mine......

Distilled water for some reason causes a reaction in the engine that doesn't occur with Tap.

You'll be just about clear and ready to fill with distilled when your first dist flush will be almost as worse as the first with tap.

I'm not sure why or what happens but it seems dist. reacts differently.

We'll see how your efforts turns out.

figure on using 24 gals of distilled. That will get you into the neighborhood of 1% tap left in the system.

That is what I used. Under the assumption that you are draining 1/2 of the cooling system capacity each time (~3.5 gallons). Seven drains and refills will, like PGreen said, give you a ratio of 99% Distilled to 1% Tap.
