nope 4.7s are not known for overheating, but of course air in the system will cause it (duh) so make sure it is bled properly, all the above suggestions are solid places to look at if the t-stat doesnt solve the issue, but ABOUT the middle of the range is normal for these trucks (mine is usually just below it)

 

Here's a refresher course for burping the 4.7.
FYI for DIY:
1) After you've replaced all the hoses and the t-stat, fill the rad with a 50/50 mix of coolant and water. Some may say use distailled water but I find that regular tap does fine.
2) Fill all the way you can, then start her up and drive for a few minutes. Park her at an incline, like when you just go up onto your driveway. Turn engine off and open the hood.
3) make sure the engine is cool to the touch before you open the rad cap.
4) Locate the orange-colored allen nut like this one at the upperhose connection on the engine block:

5) Start the engine and take off the rad cap and return to said allen nut and using the correct allen key, crack loosen the nut until you can hear air hissing out.
6) Start filling the rad with coolant mix until you can see coolant seeping out of the nut area.
7) Tighten the nut, replace the rad cap and there! You've just burped your 4.7!

 

hydra, put dans post in the FAQ somehow its a good one (and i havnt seen another on the site for burping the 4.7)

 

got a new t-stat from the dealer today. got it all changed out and put a bottle of water wetter and distilled water. we shall see if it keeps the temp down any.

also changed the oil today as well.

 

Thank you for the reco, shrps!
