Thanks!
Yes, in fact the popular Prestone flush solution's "heavy-duty flush" which I did means driving with the flushing solution many miles for many hours before draining and rinsing.
Great excuse for a 2-day road-trip
For drain and rinse, I also run water through the system for a few minutes with engine hot = thermostat open, let it cool, backflush again with garden hose. Repeat. I admit I like overkill when it comes to cooling system because the common issue with all our vehicles had been with the cooling system.
