Coolant Flush Question

I just Fluhed my Coolant out & replaced the Ford Gold Coolant with Preston Cat-1 rated ELC. When I flushed the system I flushed it with just Distilled water. I did not use tap water on any of my flushes.I flushed it 4 times with distilled water. I had the drives side engine block plug out & the radiator petcock open.I did not backflush the EGR oil cooler. My concern is that could I possibly have left just a little restore in my system & If I did what could be damaged? Thanks everyone

After four flush/fill cycles, I have my doubts there is enough in the block or cooling system to worry about. If the water you were draining out was clear then then you got the Restore out.

Thank you Zilton. The water was clear. I tried to check the PH level with PH strips that I got at Walmart. If I read the strip right, the PH was about 7. After you telling me that, I am relieved. I was just worried that maybe I just didn't get it all. That was the first time that I flushed my Coolant since I bought my 6.0 last sept. I would have done a complete flush with backflush, but I was pressed for time right now. Thank you again
