Terrapin

Hey everyone! Had a bothersome issue when I parked last night. Jeep made a sound like air being let out of a tire, smoke was coming from under the hood and into the cab from the ac vents, smelling of coolant. Popped the hood to find a prodigious hole right above the metal clamp on what I believe to be a heater hose. I found a picture online and would like to ask for assistance with identifying it. Thank you in advance for taking the time to read and possibly helping!

Yes, that's the host that goes from the thermostat housing to the heater core. The return hose is right below it and of slightly smaller diameter, IIRC.
