Need help with ELC coolant change and oil cooler issues

[James314]

Hi I'm new to the forum and just entered the diesel world by purchasing a 2006 6.0 powerstroke. I'm in sort of in a sticky situation. I bought this truck with 142000 miles on it and now 10000 miles later the HPOP goes out. I know this is uncommon for a 2006 model but it leads me to believe that this truck wasn't properly mantained. The truck is at the dealer now getting worked on but here is the issue: Prior to getting stranded and after reading everything on here about switching to ELC, I was on my way to get Restore and Restore plus to do the coolant flush myself. I also had a brand new oil cooler on hand from previous plans I was going to do with this truck but that is WAY a more lengthy explanation. Anyways I told them to put the new oil cooler in (just for preventive measures) and as you all know they recommended Ford Gold poop. I know its better to do the flush BEFORE since you run the risk of plugging the new cooler. I also have a coolant filter kit that I will be installing. Should I just stay with the new Ford Gold coolant that they will be putting in or can I do the Restore flush with the coolant filter installed? I don't have the extra time or money to have my oil cooler fail in like 100 miles and get it replaced again. Does the ELC (I bought the Cat stuff cat ec-1 rated) absorb part of the crap thats left in there? I know it is a waste of money to put the Ford coolant back in but I have to have my truck running at least to do the flush....lol
