Help identifying part

Hello! Could someone help in identifying what this part is called? Just noticed this small leak and the liquid is really light in color but gives off a smell. Can’t pinpoint what the liquid is as im not too familiar. Car is a 09 V8. Thank you in advance!

 

Powersteering?

 

09 V8
What car What side?
Looks like right side but some camera's swap sides

 

Might have found the culprit. Coolant reservoir is almost empty

 

Limited 09 V8 and driver side

 

While inspecting that leak, i noticed wet spots above it. Followed it and saw more spots closer to the coolant hose on driver side. Checked coolant reservoir and is almost empty. The “leak” from the metal tube smells the same as the coolant dripping from the hose on top. Hopefully it’s not 2 leaks and just fluid that came from the hose! Unless that metal tube is a coolant line.
