Don't be surprised if its the upper hose. (Hope it's the upper). I just replaced mine. Was dripping just right from the upper onto the lower which made it appear to be the lower.

That's what the SA said. Not too man lowers but there is a fresh post with some members that just had lowers so I bit my tongue on saying that.

Ill check the paperwork again, I think they put new o-rings at the dealership. Good thing is, I haven't had to do a coolant flush since my coolant seems to be replaced every year or so due to coolant leaks. Then again, same deal with my Cummins

Do you have the newer hose design? I think they have multiple o-rings at each connection.

What is the coolant capacity and is there a better alternative to the Ford coolant? Will be deleting my EGR and replacing both rad hoses, due to weeping coolant.

thanks

After reading this post I think I might replace all the o-rings pro-actively when I flush the cooling system this fall.
