Yes Pinetree, the "KISS" principal is good if it works. I really wanted to locate that thread I read before doing what I did, because Bolters were talking about pulling their engines out and replacing them. I certainly didn't want to do that!
And again, there's no evidence that it was the only culprit, since I changed out the radiator too. But when I saw the color of the solution when I flushed the system, I believe it had to help.
Good luck with yours!
