Well, I am a new owner of an 03 F-250 4x4 CC. I have a question as far as my build date for my motor. Where do I look to see when it was built and what should I watch out for?? My truck was built on 12-14-02 but am unaware of where to look as far as my motor.

 

Look behind [rearward] behind the FICM module on the drivers side above the valve cover. From reading some of these post it seems likely the date on is the date the sticker is printed and not the day it was made.
