You're running too hot for a 5VZFE, but you're not going to hurt anything in the near term with those temps. Needs addressing though.
Inspect items in order from easiest to most intensive:
1- Radiator cap. If not keeping pressure, you can heat up.
1a- Inspect coolant level and condition. Is it low? is it murky? Is your overflow tank empty?
1b- Inspect radiator itself. Is the top of it coppery brown colored? Any cracks anywhere? Have you ever replaced the Rad? If yes to any of these, time for a radiator and coolant flush with Toyota Red coolant.
2- Fan Clutch- Test it. Search Youtube for Timmy Toolman fan clutch test to see how.
3- It could be your Thermostat jiggle valve in the wrong position. You'll have to drain the coolant from the radiator, remove the lower hose, and remove the thermostat housing to see. It's not too hard. the little wiggly valve needs to be at the BOTTOM 6 o'clock position, not 12 o'clock as many techs mistakenly install it wrong.
4- If all of the above checks out, when's the last time the water pump was replaced?
Just a starter list!
In my case, I was running 209-211 on the highway. My jiggle valve was the culprit. After putting it at 6 o'clock, I never go over 194, even in extreme duty.
