08 6.4's don't like dex-cool
Guys my trucks under the gun right now
Yesterday replaced radiator, finally started leaking
Water pump was destroyed, replaced
Checked for catoivation and nothing!!!
Took off radiator and literally chunks of red clay came out.
Degas bottle had chunks... Flushed it 10 times and it runs good...
First time though it was black and crusty on the bottom of the degas bottle... That's normal right!? Coolant didn't have I black oroil whatsoever and oil is not milky..
What can it be?! I'll post pics of truck later
