So I flushed and switched to the this http://www.powerstroke.org/forum/general-6-0l-discussion/183020-what-zerex-elc.html#post2259068 today and I have to say that I was SHOCKED at what came out everytime I flushed the system. Here is how I did it, simular to what Gooch's method minus the t fitting for the garden hose.
I initally pulled the top and bottom radiator hose and the drivers side engine plug. I also removed the thermostat. Then stuck the garden hose in the degass bottle, top of the radiator and the top of the engine thru the top radiator hose to initally flush the Ford Gold Coolant. I buttoned everything back up, filled it up with the garden hose and then ran the motor a few minutes with the heat cranked. I did this twice.
Everytime I drained the system into a white 5 gallon bucket to see the color and what was draining out.
I put the old thermostat back in.
Next I filled with 1 gallon of Restore and 3 gallons of distilled water and ran the engine with the thermostat in for 1 hour at high idle with the heat cranked.
Next I filled with 2 qt of VC-9 and filled with nearly 4 gallons of distilled water and ran the engine with the thermostat in for 1 hour at high idle with the heat cranked.
I took the thermostat back out.
Next I filled with distilled, ran the engine for 5 minutes and flushed. I did this 3 times with out the thermostat in and on the third flush, it was as clear as when it went in.
I installed the new thermostat and buttoned everything up for good.
I fillled the degass with 4 gallons of the concentrated and ran the engine till it got up to operating temp and topped it off with about a qt of distilled water to the "low" line on the Degass bottle.
All said and done, about 3 hours. Next up is the coolant filter that I'll put on tomorrow unless it is too cold outside.:hehe:
One thing that I did notice is that the old thermostat showed considerable amounts of wear and kept the engine between 182 / 184. The new is keeping it about 192 / 194. Before the flush my EOT was usually 10*-15* higher than ECT. Tonight, driving in it was holding 17* difference at 75mph. :doh: So, my next move is rebuilding the Oil Cooler and possibly deleting the EGR cooler.
