I know what it is, but not where it goes. I might be blind or dumb lol. If it's not clear in the pic, it's the hose attached to top of the coolant reservoir.

 

Mine just hangs down. It's just to let excess coolant escape if it overheats or gets overfilled

 

Mine hangs low, I let it waddle to the floor.........

 

You can tie it in a knot or you can tie it in a bow, but what ever you do, try to refrain from throwing it over your shoulder like a continental soldier...


But on a more serious note, cleburne is correct. It just hangs down in the area of the passenger front wheel area.

Try to keep it routed out of the engine bay side of the inner fender otherwise it'll find itself resting against the passenger side exhaust manifold and just melt against it... ask me how I know...
