2002 Yukon Coolant Flush/Change

[xTheOlahx]

I have an 02 Yukon I had got almost a year ago. I have done about everything else need be before winter but the last thing I would like to do is change my Coolant. The coolant still looks clean and pinkish so it appears to be Dexcool. But my question is how much radiator fluid would be required to do a change or flush and the procedure on doing this. I also have rear climate control so I also have a rear heater-core as well which would require more fluid. Thanks for the help!

I ran a chemical flush with two bottles of prestone super flush and distilled for a few days and then used less than two gallons of non premixed dexcool and an equivalent amount of distilled water iirc


Yukon xl Denali with rear heat also.
