Another coolant flush question.

I have 78,000 miles on my 2010 and It's been "mine" for about 2 months. My ScanGauge shows a delta of 2*. The PO did an outstanding job of maintenance, I have all the records. The Ford Gold coolant is still in use and appears to be the original coolant. I have not tested the nitrate level. I'm considering whether to just drain and refill with the Gold and add a filter and continue to replace the Gold every 3yrs. or so, or change to Cat ELC-1 and add a filter. If I change to CAT ELC-1 it will be necessary to flush with VC9. I certainly don't want to cause any problems with the oil cooler. I plan to keep the truck for a long time. I drive it a couple of times a week and tow an 8000 lb. 5th wheel several times a year. Can I have some advice on these two courses? Thanks very much.

I never used any chemicals when I switched over from the ford gold and it has been working fine. Just did a bunch of extra flushes with water.

WHS^^. If you are worried about your delta just do a bunch of distilled water flushes, add a coolant filter and refill with EC-1 coolant.

I bought mine in Jan. with 83K on it. The carfax showed it had a rad replaced at 43K so I assume the coolant as well. The nitrates tested off the wall so I decided to do the prescribed flush now so I start with a known baseline. I had Ford do it because I still have some warranty left. The tech showed a lot of scale and some rust that was removed.This scale is what plugs the coolers; also the inhibitors settle from the coolant. I had the trans hot flushed as well,this is important to do a HOT flush as this opens the internal stats and allows the torque converter to be flushed and all the fluid gets changed. It cost me $900 and I think that was a lot but they spent a day and a half at it so...

Yeah, the PO had Ford do a trans. flush at 54K. As far as the coolant, I'm cheap and will do whatever myself. Just not convinced what to do.
