My dealership added an engine block heater (have them on the Ford Excursion and my daughter's 4cyl (gas) Escape); they're just nice to have when it gets really cold.

Here are the P/N's:

4M6Z*6B018*AA WIRE ASSY
F5RZ*6A051*B HEATER ASSY
5M6Z*10B689*AA WIRE ASSY - CHARTGER HIGH VOLTAGE

Tried to add this to the order after it was submitted (option 41H), but due to how quickly the vehicle was ordered/built/delivered...less than 5 weeks.....it was too late by time the paperwork went in, as the vehicle was 'accepted for production'.

Interestingly enough, the engine block heater is not shown in the brochure or the regular Ford website, it is found on the Ford Fleet website:

The engine block heater is listed under Major Optional Features, Fleet only.
