Thanks for the info fella's. I thought it was a bit on the lower side. I just like to keep my truck running right. I personally thought it was the thermostat as well.
Its nice to have some numbers to compare to.
I hope to receive my motorcraft replacement soon. With the weather the next 6 days or so showing rain, snow, sleet, and freezing rain. I may have to put this off for a bit. It's not my daily driver anymore so I can afford to wait. Here is my daily driver.
A tad different. I do drive my truck a few times a week though, just because its much more fun and nicer. Plus when I take my kiddos to and from day care I usually take the truck.

Just got mine replaced last summer. My truck was running without fail between 190-195. After Ford installed a new thermostat along with thoroughly cleaning my radiator, my truck now runs between 194-204 on the extreme high side, depending on the time of year and during hard use). I went back to Ford and asked them what the hell and it was told to me that it all depends on what thermostat gets installed.
