my degas bottle looks like sheeeeet!

[Capt dong]

should I be concerned? lots of brown caking on the sides and bottom and a light sheen on top of the water. no tarballs as of now. is this a symptom of a problem? was planning to install a coolant filter.

had the radiator replaced at 38k miles. now at 49k miles. no leaks anywhere. egrs still in place. mini max on wild tunes the last 400 miles.

I don't know what’s going on, but something defiantly is. In the words of a good friend of mine "That just ain't right boy".

Mine looks similar, thinking of changin coolant and doing a filter install. Any other ideas folks?

Do a chemical flush and get rid of the Ford crap coolant. There are a ton of DIY posts on flushing.

Did u figure out what ur degas problem was? Oil cooler?

It's already mid to upper 80's here in Houston. Driving unloaded around 70-75mph with a hot tune my ect is 195-199 and my eot is 201-207. So the greatest difference has been 8*. A little hotter than I want it to be especially reading the temps from other members.

Luckily there's no oil in the coolant. Gonna do a Blackstone test on the oil as a precautionary measure for cavitation and other issues. Been running my coolant filter for a couple weeks. Well one week cause I had the lines on backwards hahaha. Soon I'll pressure test cooling system ( just got a kit. it might be excessive but I'm sure I can use it for other future autos.) The black sandy stuff I'm hoping is casting from the block and not a cracked egr cooler exposing soot into the cooling system. The gold coolant seems clean besides the walls of the degas bottle.

If everything checks out ok then I'll do a full egr delete and then a proper coolant flush with restore and restore plus. Already have 4 gallons of cat ec concentrate in the garage along with 20 gallons of distilled water.

Sounds good Capt. Keep us posted, I am fixing to do all the same stuff. I have the coolant filter in the mail.

you need to get the degas T line update done! the two line setup was bad about causing cavitation

well that just pisses me off. i had the radiator replaced at the tune of 1400 bucks right outside of the 3/36 warranty and i mentioned it to the service guy and he just blew it off. when i first got my truck i knew it was an issue comparing pics and all but couldnt tell the difference since i wasnt used to looking at it.

Ya take that sucker in to get the tsb. Don't want air pockets causing cavitation in your front housing. Lots of guys experiencing that.

I'm seeing similar temps on my 2010. It's getting warmer here in charleston sc so I'm assuming it's due to that. I have an egr delete and fresh coolant and still seein those temps. Keep us posted on ur findings.
