NC Hornet had a real thorough write up in the 7.3 subforum but I did not see anything in the 6.0 subforum. NC Hornet listed removing the drain plugs in the block on the 7.3, I guess that's not part of the procedure on the 6.0? He also listed taking out the thermostat for the flush procedure and taping into the heater core hose with a garden hose to flush the system. How many gallons of coolant do I need for the 6.0?
