It runs at 95 C at highway. When i got the truck it ran at 92/93C. On acceleration it will cool off to 92C. Sitting idling it will go continuously hotter until i rev it up to 3500 rpm. Then it cools down right away. If i turn the cab air on hot it will cool off a bit.

I have a chip to see my temp. Any ideas?

Water pump or fan clutch or thermostat not opening or a clog in the system.
