There seems to be questions that come up regularly about the right coolant for your 6.0 or 6.4 Most guys recommend Cat EC-1 ELC because the silicates in Ford Gold/G05 have been suspected of dropping out of suspension and clogging oil coolers. That said, the Zerex ELC has silicates, it looks like it's the only Cat rated coolant that does. Also some brands have different corrosion packages so it's not a good idea to mix coolants. I found this chart some time back and it may help you guys with coolant questions. http://www.eetcorp.com/antifreeze/Coolants_matrix.pdf
The matrix thread has been taken down, I tried to attach it here with an edit but for some reason it's not uploading. I did attach it on the last page of this sticky along with some flush instructions, good info on the Fumoto's and back flushing the oil cooler. However I highly recommend disregarding the chemical flush section and use Liquid Cascade dishwasher detergent, the stuff with Dawn is the best. (Don't use Dawn dish soap!) Make sure after any flush with a garden hose that you do 2 or 3 (or 4) fill N drains with straight distilled water since you can never drain everything out. Then when you're ready for coolant Use 3 1/2- 4 gallons of concentrate, then top off with distilled. Don't use 50/50 or it'll be weak because of the inability to drain all the water.
