He won't cringe...I think it'd be a wry grin.

You should read more and plan on flushing out your system...rinsing a couple of times with distilled...drain each time from engine block plug until what you drain is clean. I drive around just a little bit...let it cool down before draining...and replace crush washer at the final fill.

There are coolants that don't intermix well and form a gunk. I don't believe this is an internet myth.
