Thanks to the fine members of F150online and F150World I was armed with info when I took delivery of my truck today. Salesman didn't have a clue!

General manager looked at my data, walked me over to the service manager and said "give him an appointment to have the correct radiator installed" They also provide a brand new loaner when your vehicle is serviced under wanrranty.

Bottom line....thanks to all for a painless buying experience. Nothing like an informed consumer!
