Even if it's a 6.0, the difference in temperature between oil and coolant isn't enough to need a new oil cooler. Are you towing, under heavy load, does it have a crazy tune? Details would be helpful. If you're just cruising along at highway speeds and seeing those temperatures, check the coolant system and fan. No DTCs?

My mistake I was looking at the trans temp and oil temp and hastily hit reply. Then I read it again and asked for the fan speed.

Can you hear your fan? It should kick on when oil is at 217 degrees, and it is impossible to miss, even at highway speed.

That's pretty high for no engine load. I don't even see these temperatures on my '06 6.0 when I'm towing straight up a mountain.

These trucks also have a water pump with a plastic impeller. The impeller can shear off of the water pump hub and, obviously, the pump is unable to circulate coolant properly. Newer pumps have metal impellers.
