I have to wonder if Fords values and test criteria even apply anymore.
3 different trucks similiar problems and none of them stock with add-on components.
Maybe you should start shooting things with a infared thermometer and see if you are actually getting as hot as the sensors are reporting. IIRC.

 

I rechecked the temperature using a infrared temperature gun and the temps are: engine 199 degrees and the oil temp 183 degrees

 

Did you by any chance shoot the oil temp sensor and see if its location made any difference?
That is only a 16 degree spread.

 

And it looks like a new thermostat will close the gap.

 

That's where the temperature came from was at where the oil temp sensor is located

 

I installed a coolant filter first before any of the other stuff
International advised me install to keep dabre out of the cooling system. If you have contaminated antifreeze will cause a lot of problems.

 

I have checked all the parts stores around here and are unable to locate any different ranges of thermostats.

 

We are at the mercy of Ford or International. Mishie has a higher temp thermostat. There are mixed reviews on it. It seems that most get 1-2 years out of a T-stat.

 

1 or two years is better than having to stop every 50 to 75 miles to reset computer.

 

can you determine what flash update you currently have?

 

I am not sure what flashs have been done to my computer according to Ford Dealer that all the update have been done..

Is there a flash that I need to asks for ?

 

Wow, a thread from 2009. A lot of old faces in this thread. Most have moved on.

 

Some days I wish the mods had a way to close out older threads. It clutters up the board, and then I find myself going back through the whole thing which sidetracks from the issue many times. Makes it harder to help when you are sifting through crap that is, at times, almost 10 years old and like you said, most of the OP's from the thread have moved on to something else.

 

Ya but sometimes it helps out with people new to the 6.0 world.
