"International truck" 6.9L cooling system capacity?

[mrroboto1975]

Have a 1986 International S1600 6.9L. Looking for someone that has an old book that lists the total cooling system capacity. It is NOT the same as a Ford (GVWR and therefore radiator is much larger). And I don't need to know how much antifreeze to buy to fill it up.... I am flushing to clear water, and need to know what half of the total capacity is to get a 50 / 50 mix.

Sorry I don't have the information you want but I know if you drain and count the gallons drained out.. you will know the proper amount. Please remember to drain BOTH sides of the block.

Just use the 50/50 pre-mix and count how many it takes to fill. Don't forget to reinstall block plugs back
