This is my first Turbo Jeep and I want to do a coolant flush and fill. I have read that I need to change the coolant in the Turbo System and the Engine itself. I cannot determine if these two systems are independendent or not. I am assuming they are one system, draining and refilling main system would replace the approximate 9.5 quarts for engine and 3.5 quarts for turbo system. YouTube channels usually answer these questions but none have mentioned it. Can someone let me know if they are the same or independent system? Also anyone have a good link to YouTube video on this? Thanks!
