Ford Escape - replace degas bottle to thermostat housing hose assembly?
No leaks,no overheating issues then leave it. Only concern at 7 years, has coolant been replaced? Cold engine remove cap and take a whiff. It should be pretth much odourless. If it has a strong odour, replace it. Dump and fill will replace 75% of it,good enough in my opinion, beats doing nothing and waiting for a coolant related problem.
i doubt it was the tech calling the degass bottle, likely the the scurvy dog service writer.
