ok, I have gone through a bunch of threads with similar problems. But nothing that described exactly what i have here. My truck has had this junk on the cap of the overflow bottle for about 6 months. The truck doesn't smoke, overheat, run like junk, use oil or coolant. This is my DD and has not towed anything bigger than a two place snowmobile trailer.
2003 6.0l, auto, 120k, sct livewire, 4'' exhaust.
thanks for any help, pics should be below.
I have owned the truck for about 8 months. I have not replaced anything yet, and oasis came up clean. So i think everything is stock. I haven't looked at EOT vs ECT yet. I cant get my livewire to show EOT.
Drain it, flush it out with VC9 from Motorcraft, then put in the yellow coolant from Ford. The green stuff cavitates the metal. Ive never tried the VC9 and just recently found out about it but its supposed to work well for the 6.0s.
