My car has been leaking coolant for the past few weeks.. I finally found the culprit. But whats the name of this hose? Its found under the intake manifold near the oil dip stick. Kinda look like a backward "L" shape hose. Thanks in advance!

 

When you go to the dealership, they should have diagram with different parts/hoses and their part numbers.
As long as you know which one, you could just go to a dealership and let them find it for you.

Best of luck.

 

I don't know this engine, but my engine has a tube from the throttle housing to the main coolant line. Can you zoom out a bit?
Also, this will mend your problem:
