Replace your thermostat with a 195 degree one. Your engine will thank you.

the dash temp gauge is not very accurate. i would shoot the engine at the thermostat neck when warmed up with an infrared thermometer to see what the temp is.
if you do decide to change the t-stat, only use a ford or international dealer t-stat. auto parts supply house units do not work in the diesel engines, and will very quickly overheat your engine.

I agree. A fresh thermostat sure can't hurt, though.

Ok thanks for the help ya'll. I'm late in giving an up date to what I did so here it is. I replaced the water pump (it started throwing the belt off the pulleys ), the T-stat ( I had never changed it), serpentine belt (chewed up from being thrown into all moving parts on front of engine), and the fan clutch ( cheap insurance since I would have it off to change the water pump ). What I found was the copper coil on the front of the fan clutch was gone! (Found it on the radiator crossmember . )Water pump was not leaking on the outside but the bearings had a hard spot in them. What I LEARNED from the ordeal is a new 180 T-stat is to cool for my engine, a 195 has since replaced it. ( Truck just wouldn't get up to the normal range on temperature guage.)
I hope my ordeal with the overheating issue helps someone, sorry I didn't post sooner.
