I had a diagnostic done and nothing wrong appeared. Replaced thermostat. Still running hot sometimes. At certain time (intermittent) the temperature gadge goes up to 3/4 then goes back down to normal (less than 1/4). A little later the same thing happens. Thermostat recently replaced. Did not solve problem. Fluid level okay.

The t stat will cause the temp to rise and fall as it opens and closes. Is it overheating? or just going to 3/4 and back down? If it is not overheating i would not worry.

Electric fan? I'm fairly confident it is. If the fan runs off the engine then replace the clutch fan. If it's an electric fan, make sure it is operating properly. If all of that is good, make sure that the coolant is moving around when you open the radiator cap. Look down in the radiator to ensure it's flowing when the thermostat opens. It may also be possible that the radiator is all plugged up. Good luck, I would suggest troubleshooting in that order.

It sounds like your fan clutch is going out. Put some gloves on and with the truck running reach down and stop the fan. it doesn't hurt if your careful, just kinda spooky to do. If you are able to easily stop it it's gone bad. that is why it gets hot sometimes and sometimes it doesn't

I can almost bet money that your radiator fan is not working. Check it to see if it comes on when you idle the truck with the air running if it does come on check your water pump as well.

The water pump might be bad..........also check the fan clutch.......one thing I suggest is to unplug the fans sensor........the fan will keep running all the time............

try having the cooling system flushed out,you could have a dirty radiator or heater core.
