Green coolant + 6.0 = bad things
You can use the Ford Gold, BUT, be prepared to continually monitor Nitrite levels.
Ford TSB on the subject of coolant maintenance for the FORD GOLD: CLICK HERE.
If that isn't your idea of fun, flush it using restore and then flush it with VC-9 (or Restore+). (restore and restore+ available at cummins dealers, not DODGE)
Then you can use what the engine manufacturer uses.
Fleetrite ELC coolant. It is available at your friendly local International Truck dealership.
The flush should go something like this:
Drain existing green, fill with distilled, run to operating temp, drain, fill with distilled, run to operating temp, drain, dump in 1/2 gallon of restore and fill up the rest with distilled, run up to operating temps and then one hour beyond that. Drain, fill with distilled water, run to operating temps, drain...repeat until the water drains clear. Dump in 2 quarts of VC-9 (or restore+), run to operating temp and add one hour beyond that, drain, fill with distilled, run to operating temp ...continue to do this until it comes out clean. Dump in 3 1/2 gallons of the CONCENTRATED form of the Fleetrite ELC (no pre-mix) and top off with distilled. With the remaining 1/2 gallon of coolant concentrate, fill the jug with distilled and use that to top off the degas bottle over the next week or two.
When running the truck, the heat should be set to full hot and switched on.
When draining, remove (at a minimum) the drivers side block drain plug. It is recommended that you also remove the passenger side block drain, but it is just above the starter and a royal pain in the ass.

The green does not offer the proper cavitation and the corrosion protection for the 6.0L engine. Not without beefing it up w/ additives, then you risk plugging the oil cooler passageways.

You'll need an 8MM allen socket and a few extensions to reach the plug on the driver's side. Easiest way to get to it is slide under the truck just behind the front left wheel.

A 1 gallon bucket will fit nicely above the front driveshaft and catch most of the coolant.
