overheating, HELP!

I changed the thermostat, flushed the system and it's still slightly overheating in idle. Once I rev it in park and turn on the A/C it goes all the way to the red. Can someone give me an idea whats happening!

Year, engine, history of water pump and radiator? Losing any fluid?

99', not losing any coolant, factory water pump, and the second radiator. This happened last week while offroading on a super hot and muggy day. Now its acting up again!

Check the radiator cap to make sure it is holding the correct pressure. Make sure you put the correct rated temp thermostat in. Most likely a 195 deg. If it is a 4 banger, make sure the electric fan is comming on. Also check the clutch fan.

What and how did you flush it?
What type of thermostat?
How's the engine been running?
What's the last several things you did to your Jeep?
(I find this is a good place to start looking)

observe overflow bottle and see how much the water raises from when the engine is cool to when the engine is running hot.

if it raises by like half a bottle then your cap is not holding pressure in.

Touch the top and bottom hoses .... is one of them hot and the other cold when the engine is running hot ???
