Coolant Issue

Hello - I just replaced my radiator and now I have a coolant leak under my Jeep. The pic below is where the leak is coming from. Does anyone know what this elbow hose below the heater hoses is called and what it does? Coolant is dripping from it onto my frame rail then on the ground. My heater is working fine, and there is no coolant leaking inside the Jeep. There is also no coolant leaking from the heater hoses attached to the heater core. Any help will be much appreciated.

I think that is a drain tube for the tray that is
under the AC and heater cores . It keeps condinsation from the AC from dripping inside and making a wet mess . Sounds like you have a leak started inside the heater box . My 05 drops water out of there constantly because of the humidity in this area during the summer when I have the AC on.

I'm beginning to think that possibly you couldn't build enough pressure because of the old radiator leaking and the new one holds pressure and caused the next weakest part to start leaking

that is the ac cond drian. are you sure its coolant leaking or could it be just water.

remember, your ac compressor runs even in defrost mode, causing condensation.
