[lil_boxx]

Hey guys got a 1992 civic cx with a 94 b18a1 manual transmission as well... I've got a hose I'm not sure where it goes and the diagram isn't very helpful so just looking to see if anyone might know where the hose in the picture below connects
Trying to find out where this hose barb circled in red goes?
Thanks in advance to any help!

coolant hose links the hose port coming off the coolant bypass pipe right below it.
