I really think it’s coming from here, and doing it when it’s under higher temps/pressures as the coolant bleeding wasn’t quite enough to make it leak.
Not sure if it's the lower hose (joint #2), or the connection between the lower and upper one (joint #1). Looks like there may be some dried coolant in the clip that locks the two together which would make me think more the upper joint but hard to tell. I may just buy both hoses if there's a chance it's the connection.
I guess there's some dried coolant on the upper hose to radiator too...that could have been from previous maintenance though. I need to clean it all off really well.
I'm going to also check coolant temps...
it couldn't possibly be "overpressurizing" the system and blowing past perfectly good seals could it?
