Coolant flush observations (2020 CX-9)

[Veroguy]

I'm in the process of changing the coolant on my 2020 CX-9 with 54K miles, using Peak OET Extended Life coolant. https://www.amazon.com/dp/ (commissions earned) The first drain, there was some gunk in the bottom of the pan, but not too bad. The second drain was good and clear. Color is identical to Mazda coolant that was in the engine. FYI, I pulled out the overflow tank and emptied and cleaned it. Takes 20oz of coolant to fill to F line.
