I highly doubt that they will need to pull the engine, at least with the Ecoboost, to replace it. If you follow the plug wire, the heating element is on the front right of the engine. Looks to be fairly easy to get to.
Just looked at mine, ordered 1/17, scheduled 1/23 for week of 3/10... just looked and its been rescheduled for 2/24, two weeks earlier. Mine is not hybrid though, thanks guys for putting me to the front of the line :angel:
