2002 Ford Explorer Condensation drain tube

Thanks Joe. The fluid pouring out smells like antifreeze. It drains with the motor running and pours after it has some pressure. I'm wondering what that tube is attached to. I have one of the enclosed radiators so the only way I can see the coolant level is thru the overflow tank and it is low but has some coolant. I haven't let it run much since yesterday when I first saw the leak. The truck has not overheated yet. Could I have a defective water pump? Is that tube some sort of overflow from the engine. I can replace the waterpump and thermostat, but I've never seen a tube sticking out from under the engine like that AC seems fine. No wet interior. Thanks

I thought it may be the heater core so I bypassed it and when I test drove it to pressurize the radiator, the leak is minimal now and it looks like condensation draining out of that tube. Before it was definately af smell. I did have the af odor inside the truck. Do you think that tube functions as a condensation drain for the ac and some kind of back up drain for the heater core. Thanks very much.

I'm having the same problem. By passed the heater core and it doesn't leak. Think it's the heater core leaking but not sure
