I did a flushing on mine last fall and dirt realy drained out off my engine cooling system. I have a feeling that it further dammaged my oil cooler. A lot of goo was left in the hoses and i never cleaned the degas tank at the time.
I replaced the coolant with Final Charge by teak and it cleaned everything that was in the system, the hoses are dry and the tank is completely clean. The filter never picked up any solids so it is now completely deluted in the new coolant. I have a feeling that the EC-1 coolant absorbed the goo from all over and now freely circulates in the system. I keep checking my degas tank and its clean and transparent. Of course I will need to flush earlier but I am very satisfied witht the cleaning the ELC did to my cooling system. And Final Charge can absorb 25% of coolant impurities so I feel confident that its what I have.
I am going to try to salvage one of my friends 6.0L in the next few weeks and see if my theory is right, anyway if there is no improvement after a while we are going to change the cooler anyway but I feel confident the same will happen to his truck as mine without a plugged cooler due to the gunk flushed out with chemicals.
I did a lower mileage 6.0L for an other friend and he wanted to stay away from the chemical flush and it was a success as his deltas never changed. It was at 5 and stayed at 5. His degas tank was very dirty with deposits and he cleaned it before the refill with ELC. He used Zerex HD ELC coolant.
