Coolant leak help

[bpb424]

Did my EGR delete this weekend (which was awful) and now I have a coolant leak that I need some help finding. The weird thing is when the truck is idling it doesn't leak. Once I shut the truck off it's a pretty steady drip.
Any ideas?

Do you have a general area the leak is coming from? That would be more help.

Ideas

ya where is the leak area? ?

check the heater bypass valve it has the vac line running into it and two heater hoses I think it's still in the same place on the 6.4

mine did the same thing

ps I tried cameras / mirrors / a scope / finally a paper towel and my finger found it .. just a loose clamp lol

This prob doesn't help but can't hurt. I can See it dripping just behind the lower radiator hose, but it's not coming from the hose

Just a shot in the dark but could it be left over coolant that got splashed around on the motor and frame during the delete? I washed mine down with water after I did my delete. The water would eventually dry were as antifreeze will stay for a while and drip.

Just a question to the OP do you notice any difference in boost pressure?

Maybe it is the upper hose dripping down through there? Mine is wet in the same area

Lower hose is notorious for leaking just bought an updated 2 oring one today actually.

Also check the hose on the degas bottle as well as the heater hose and plastic tube near the water pump housing

I had the same problem after I did my egr delete. Upper rad. hose didn't leak before but leaked after I put it back together. It wouldn't leak when running but leaked like crazy after shutting it off. 5 dollar o-ring stopped it.

Thanks for the tips, I'm gonna tear into it tonight after work.
I'm Hoping I don't have to drain much of the coolant out.

hose

Mine was just leaking the other day so i drained out the coolant and cleaned up the aluminum and inside of the hose. it isnt leaking anymore but i am going to see about getting the updated hose today.
