I had to replace the radiator on the Suburban last summer. After running DEATHCOOL since 1999 the radiator tanks were 1/3 full of orange greasy crap! I was seriously thinking of putting G-05 in the truck, but I did not want to have issues with mixing it with the remains of the Dex...
FWIW, I did a citric acid flush on the truck a couple years ago and it still was full of gunk!
