Need Help Identifying a part

[Golden Gate]

good morning everyone I am new to this site but I have owned fords all my life of 50 years. Normally for me they have been bulletproof a great value and faithful tool. But recently I have begun to have issues with a 2008 F350 w the 6.4. One day after moving a machine I realized the truck was running hot. upon inspection I was lacking fluid in the tank and later ended up adding 3 gallons of water to bring it up to the cold fill line. that said since I have a 200k warranty I decide to take it to the dealership where I bought it since I could not see any water at all coming from anywhere and since 3gal didn't just evaporate...fast forward their diagnosis was the upper and lower radiator hoses were leaking and needed to be replaced plus the radiator needed to be flushed and it would of course need 3 gal of coolant and water their price $700. I about fell over but said thank you very much and took the truck home well today I got around to looking at it and have determined that the upper hose is NOT what is leaking there is a threaded fitting just above the elbow of the upper hose with a hose/pipe coming from it that is dripping onto the hose. The dimwit tech at ford had I let them would have done all of the above I would have still had a leak, anyway my question is what is that fitting just above the elbow of the upper hose

Is it something to do with the EGR cooler? I looked at mine but I am not sure exactly where you are talking about

I'll look at mine when I get home.

the brass looking thing in the pic (I hoped I posted right) is what is leaking it even has a drip of coolant on it if you look. I can't believe I got this pic, someone please tell me what it is I see and 2 please tell me it is covered under warrenty because it don't look like fun to fix since my lift won't handle an 11,000 lb truck so I would be on my back at best

Nevermind fellas it is the upper hose, the bolt in the picture is just a bolt and thge problem is above that in the upper hose

Just go get a new O-Ring for the upper rad hose and swap it out. Lube it with some coolant and be careful not to nick it upon re installation. Ford part cost around 7 bucks if memory serves me correct and that's the part that dries up and fails over time. Be sure to remove the clip first to remove the hose, just put the clip back on the hose and the slip it back over the thermostat housing and you should hear a click when its fully seated. Just refill and burp the cooling system when done and you should be good to go. Very common issue on the 6.4 but a cheap and easy fix.

You know what I will do just that. I was going to spend a $100 bucks on the upper and lower and the two O rings but I think I'll just try the o ring truck only has 61k on it and the hoses look new but I'm going to do a flush I know I need 3 gal of straight coolant + water but whats the best way to flush the system the coolant is kinda cruddy..Recommendations on coolant anyone?

I used the peak final charge elc coolant. Also you will need 4 gallons of coolant. It will take about 3 1/2 to get the proper 50/50 ratio.

Oh and also when i flushed my system i used VC9 and a lot of distilled water.

You mean 3.5 to 4 of 50/50 or 3 to 4 of 100%? what about air, I hear nightmares about air pockets
