My son called about his (new to us) USA 2001 Saab 9-5, 4 cylinder wagon. It leaked coolant under it, and underhood on the high part by the hood latches. He found a small hose disconnected. One end is attached somewhere near the left headlight / directional. The other end is disconnected. Where should it go? (See attached photo.) Thank you in advance for any help!
