08 6.4's don't like dex-cool

[ramonpowerstroker]

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

Why would you put dex-cool in your truck?

[ramonpowerstroker]

No i didnt. Recently got flushed by my dads friends.. (i let him borrow the truck) saw the coolant bottle and instantly knew it was dex-cool. Ignored it found a thread about it Thursday and yesterday it gave out
