2000 Expedition Leaking Antifreeze from above Catalytic Converter

I parked my 2000 Expedition today and shorty there after I noticed a puddle of antifreeze under the truck. The antifreeze looks like it's leaking from above the catalytic converter shield.
Any idea where the liquid is leaking from so I can repair it?
Thank you,
Brimis

Get a pressure tester, pressurize the cooling system, and use a flashlight and mirror, if needed, to identify the source.

It would be helpful to know which cat, because there are different leak points on different sides of the engine bay.

The leak is on passenger side. I needed to drive the truck today for work. After the truck was parked for about two hours, another puddle.
I snapped a picture from where the leak may be coming from, just can't find it.
Thank you

Looks like it could be leaking at the heater core and then leaking out the A/C condensate drain hose.

I'll check just as soon as I finish the brakes on the Mazda. The weather changed from sunny and 90 to rainy and 90 in minutes in NJ.
As always,
Thank you

Alloro,
You're correct, the anti freeze is leaking from the front heater core. As a temporary fix I disconnected the front and back heater core hoses and bypassed them with a 3/4 inch hose. The truck is fine for now. I'll get to the actual heater core swap just as the cold weather sets in.
As always,
Thank you
