Ok you have a couple of good options:
(1) Simple Green straight solution pour in a few cups and run it up to temp and repeat several times as needed.
(2) Liquid Cascade 2/3 of a cup or so and run up to temp and repeat as necc.
You may want to do Simple Green first and then move on to Cascade to finish it up. I used Liquid Cascade on my cooling system when I switched over to a ELC-1 coolant and was very happy with the results, I was not going to put a acid in it and create a problem with my oil cooler. These cleaners are much more mild but will break down the oil and get it out of the cooling system.
The heater works much better now after using it, I now have put on around 9,000 miles on truck and my Delta temps are still in the 4-5 degree range so it worked well.
Now you should install a coolant filter on the truck to help protect your oil cooler and when you do flush the system pull all the hoses off coolant tank also the heater return line on passenger side as well as the upper and lower hoses. Run a hose through all of them in both directions and don't forget to pull at least the drivers side block plug to get the heavy debris that settle to the bottom of block.
Do all of this flush work WITHOUT the thermostat in it to ensure good flow throughout the system. Engine will take alot longer to heat up but you need to get it up to at least 170* to get the oil thin enough to flush out. Go for some 30 mile trips on the highway, that will do it.
Good Luck with it and take your time to get it all out............ Get yourself a new "OEM ONLY" Motorcraft thermostat and install when your done. Also a great time to get the Ford Gold out of it and go with a ELC-1 type coolant 4 gallons will do it only buy straight 100% coolant and top off with distilled water.
Oh yea the last coolant flush needs to be done with distilled water only so you get all the hard water minerals out of the cooling system.
Now I'm done.. .. .. .... ..
