Figured it out, it’s a power steering hose that goes to the fluid cooler.

this hose is leaking a reddish fluid on my 2007 Aurion. It’s basically underneath the drivers side headlight and connects to a small metal pipe that is about 20cms long and loops around. My first thought was it’s the transmission oil cooler line. 

can anyone give me a part description or number from the photo? Leaky hose circled in green. 
thanks for any help!
