I did a couple of drain and fill cycles with distilled water, and then installed the Kia Long Life coolant that I got at the dealer.
It says on back that it was made by Idemitsu, and lists phosphorous as one of the major ingredients, so I assume that it's a P-HOAT.
The thing that suprised me was how dark green it is, it looks almost black in the overflow tank. Kind of a bummer, I think, because if you didn't know any better, you'd say it was dirty and needed to be changed, even though it's brand new. I think having coolant this dark colored is a dumb idea, but oh well. As long as it works, I guess.
Makes me wonder if the Ford Specialty Green also looks like this. I think it's also an Idemitsu fluid.
Anyway, this is the 3rd fluid change on this car in 65K miles. First at 30K, 2nd at 47K when I got in a rear-ender and needed a new radiator, and now at 65K. Frankly I flat out forgot about getting new fluid at 47K and thought I was 5K overdue on my 60K coolant change. The old coolant looked similarly dark and now that I saw the new stuff, I don't think it needed to be changed.
I think I will run this coolant to 100K and change it out when I change the spark plugs. Kia recommendation is 30K but other Asian manufacturers run much longer with Idemitsu made coolants. I think this P-HOAT can do 35K.
