Great video- I guess you can only hope that chips from the impeller don't circulate around then get stuck in the head ports somewhere and restrict the water flow..... I had that happen to me years ago on another vehicle causing a serious overheating issue....
That’s what I was a little worried about. But the only way to find out is to either run it and see or remove the heads. Pulling the heads on these coyote engines isn’t real easy so we opted to just run it and see. He has been driving it daily for a year after this repair and no issues. Thank goodness!
