Cummins CAC

I was at an FMCA rally once and a seminar guy told us that you cannot tell what type of coolant you have by color. Based on that and what I have seen, I do believe he wasn't throwing BS. I use the Fleetguard EAS Compleat and it is blue for whatever it is worth. I have never seen any red stuff.

What about your CAC? Any luck? Oil cooler attached? I'd look at mine but the coach is in Oregon getting an interior face lift.
