So I have the wrong coolant in my 2011 MCS and have a couple quick questions.

1. The capacity is 1.575 gallons right? Does this mean .7875 gallons of pure coolant + .7875 gallons of distilled water or is it 1.575 gallons of coolant + 1.575 gallons of distilled water for a total of 3.15 gallons of fluid?

2. I’m going to follow the guide in the link below. Is that fine and will get all the old coolant out or do I have to do a flush (not too sure what that entails)?

thank you!

1.575 gallons would be the TOTAL capacity.
