Ford Escape - replace degas bottle to thermostat housing hose assembly?

Is this a Ford "thing"?
I "googled" degas bottle to see what it was. ("Degas bottles have been extensively used in vehicles in order to act as an air pillow on top of the cooling loop and provide space for expansion.")
Looks like commonly used on Ford Powerstroke diesels.
Sorry about the thread hi-jack... Hope the OPs issues gets resolved.
