Hey guys I come to you in a time of need. It snowed almost half a foot today where I live and on the way home I hit something and it dragged a little ways under my front axle. My engine then started squeaking a little bit when accelerating. Got home a few seconds later and there was a hissing noise coming from under my truck. I'm 99% sure it's this hose/connector because when bending it down towards me the noise stopped. The part is right under the radiator fan and I tried taking a few pictures. The arrow is pointing at what I pulled on.
The aforementioned hissing stopped after about 5 minutes. I started the truck again and revved the engine slightly while in Park. No more squealing like on the way home. The hissing noise did return a little quieter too. I think it was only air flowing out of it, no liquids. Not sure if that little bit of moisture was there before getting home or from leakage. There was also a tiny bit of green liquid (antifreeze?) at the bottom of the fan right above it.
Anyway, I was wondering if anyone knows what this hose is called and what it does? I'd appreciate any help. 2002 4.0 V6 4x4 Ford Ranger

this is where the right side leads to
