Diesel running hot.

I have a 84, 300sd which is now running 20 degrees hotter (at 100). Replaced thermostat, radiator ok, no signs of oil or bubles in expansion tank, hoses ok, heat works, v-belts ok, fan still there. Noticed that the temperature guage does fluctuate from time to time, as does the fuel gauge.
What do you think?
