Hello - sounds like you know the problem.....the heater core is bad and will continue to leak. The one pick, is this the hose you are talking about? This is the drain for the HVAC. Normally the condensation from the AC drips from here. So the floor board is wet due to the heater core leaking and it also draining out of the hose and the HVAC is filling with antifreeze. The other pic shows you the inside of a HVAC and the drain hole. This hole is a tube and the rubber hose you see inside the engine compartment is connected to this.

Remove the two heater hoses from the heater core and connect them together.

That hose that isn't connected to anything is the drain hose for the water that condenses from the humidity in the air when the air conditioning cools it. Coolant leaking from the heater core drips into the same drain pan.

Thank you both on the info. It was very helpful I will get it repaired as soon as I can gather the money for repair and undo the hoses temporary connected. Thanks again.

I had the same problem and the fix by the mechanic was to put a silicone based sealant at the point of contact for the drain pipe with the body. Ensure the drain pipe opening faces down towards the floor. Best of luck.
