Bought 20 gallons of distilled water and oil cooler backflush kit. Hopefully soon I'll be flushing the gold coolant out and switching to red elc. Just wanted to run this by you guys so I can feel comfortable with the project and not miss something.
I do not have any coolant temp or oil temp issues. I did a flush with VC-9 before the oil cooler replacement about 10k miles ago.
Will a simple yet thorough flush with water in combination with the back flush kit be good enough to switch to red?
My deltas are fine but considering this as preventative maintenance item. What backflush kit did you go with? Do you have a filter on your coolant system too?
I just did a series of drains and fills with distilled water until it was clean. I did not backflush. I do have a coolant filter, but again ... my system was and is very clean. No rust, no scale, no silicate gel. If the temperature differentials are fine, then I don't see the need for ANY chemicals.

Your alls experiences, opinions, and knowledge are all ways appreciated. I can read for days but still lack the confidence on doing certain jobs on my truck and doing it RIGHT without over looking something.
When I did mine I read there was two chemicals that were needed to be used to insure there was no gold left. If you mix the red and gold they would gel or something. I would have to look and see what I used. restore sounds familiar but it was two different ones.
Well I'll be the documented Guinea pig I guess. I'll run to the RV shop and grab 2 water filters. One for the flush and 1 for the camper (due for a new one). Remove the thermostat cause this dude runs cool unless a load is on it going up an incline.
Drain the old and put straight filtered tap in while flushing the oil cooler. Run her up to temp (197*). Drain, probably do it again. Drain, start a driveway flush with distilled. Then, bring on the ol' red stuff.
(I know the tailgate is scratched all to hell, can't help it, she is a working girl with multiple jobs and does the jobs well)
If I ever have an issue with muddy coolant I'll update the thread.
(The RV filter may be a waste but it makes me feel better about it)
Iron oxide is magnetic. The blue may, or may not be an issue. The main area of the gaskets does have coolant moving through. It's a very small amount, but it's there, somewhat acts as a cooling medium for the head gaskets per the guys at Felpro and over at Federal-Moguls engine test lab (different sites). Which kind of makes me wonder if Cosmetic with it's full covering is doing anyone favors.
You could be showing the residual from squeeze out, at the fire ring or the sealing rings.
