Master Electrical Overheat Shutdown MECS Pump Replacement
 

This used to be a real common failure of the Escape hybrid. While most have been replaced this video is proof there are still Escapes out there driving around with the old style pump. If you plan on going on a big trip and still have the old style pump that is currently working it would still be worth your while to watch the first part of the video showing where it is and how to get it working temporarily so you can continue on. If yours did fail already I go over replacement of the pump and proper bleeding of the cooling system. I Hope this helps.
