To help prevent the coolant from flowing into the intake during your flushing process, you can just unplug the EGR valve. Unplug it when the truck is cold and off. It should be OK to do this for your flush, since your not likely to overboost it and force the valve open and since you will be relieving the pressure on the cooling system, the chances of hydrolock are minimal.
Unplugging the EGR valve will throw a code and illuminate the CEL.
