2020 Expedition Max coolant leak

[gpk1961]

2020 Expedition Max with 117,500 miles. Dealer maintained. Noticed coolant on the driveway. Leak is dripping off the two large hose lines that go into the lower radiator, but it appears that the leak is from above and running down the plastic tube.

The insulated hose looks like it scrapped against the tube and wore causing the leak? Don’t see coolant anywhere else. (see the pictures)

Is this line a heater line?

Is the lower radiator for the turbo system?

Thanks – Jerry in McKinney TX

Looks like a heater line.
Those are common leak points on the Gen 4 Expeditions. if they haven't been changed on yours, I'm sure they are the culprit for the leak.
Where the heater lines enter the firewall, check and see if the metal crimp around the lines is splitting, that is the first sign their leaking.....
