Inside of coolant bottle

[jwsland]

All the issues I have and my coolant bottle was even one of them. The threads were messed up from my cap. It blew off one time. Its been changed a few times, taken off two hundred times when the truck has been worked on. Well I cut the bottle open and heres what the inside looked like.

Wow looks like you need a flush bad. I noticed your signature says bulletproofed does that also mean an oil cooler? Even if you have a bulletproof oil cooler I would flush my cooling system to get all that junk out of it.

Looks like typical engine oil cooler failure...

Truck was flushed for 12 hours with restore/ restore plus. Coolant filter and brand new oil cooler. Using CAT elc. Eot and ect never get more than 5 degrees apart. I think the bottle was ditry from before I flushed.

It is possible that is from before the flush. A lot of us don't think about checking degas bottle after or during a flush.

Now to put it in perspective. If the degas has that kind of crud in it, just think how much was in the hoses, heat transfer devices, and the engine. It's great you are getting it all sorted out.

True, The hose on the bottom of the bottle looked clean. I change my coolant filter often and always cut them open. They paper is always dirty but never any of that gunk in there.
