There is a black hose going into the passenger side of the firewall, I believe it is leaking and my coolant is low. What does it go to?

Hello, I'm Danny.
Those two lines going through the firewall are what feed the heater core.The heater core is mounted inside your car in the HVAC unit and is what warms the car when you turn the heater on.Here are tutorials showing how to replace the heater hoses and the heater core.
