hi,
that would be a main coolant hose, going to a plastic main coolant pipe,
and they have a metal insert in the end of those plastic main pipes..
those  metal insert ends are famous for sliding out of the end of the
plastic pipe a bit and then it leaks there.

there's a repair kit ..
but that's not on the tower. .
