Engine Temperature Seems High
I'm not one to start throwing parts at a situation until I find out what's wrong. Remove your radiator cap cold, start the engine and watch the coolant as she warms up. If you don't see the coolant moving when it's hot replace the thermostat and coolant since it's never been changed.

Just went outside and tested what you said gary. I removed the cap watched it warm up the coolant was just trickling out where I removed the cap. The coolant level didn't move at all in the container either. Both fans did kick in at 207F. What's my next move?

Did you ever fix this? I seem to be having a similar issue with mine. Not 235F but around 215-220F after driving for 30+ mins and that's still too hot IMO. changed the radiator cap, checked the coolant level it's all good. I'm hoping it's only the thermostat not fully opening up. Fans operate perfectly too.

I am another in this overheating club... unfortunately i cant help but i can add what i have encountered.
Car reaches 3/4 temp within 5 mins (regardless of ambient temp) and stays there the whole time. Lower rad hose never gets even warm. Coolant never leaks. It has been like this for a year.
In the past month I have:
Flushed the coolant and added water wetter...... no difference.
Replaced the thermostat.... no difference
Replaced the rad cap..... no difference
Replaced the radiator..... no difference
Burped the coolant many times... no bubbles, but the coolant will slowly overflow the "spill free radiator filler" while the engine is running...then all drain back in within a minute of turning the car off.. im hoping this is just from fluid expansion and not a blockage because this filler can contain a gallon (4 litres) before it overflows, which seems like quite alot of expansion to me...
On a side note, with my regular "spirited" driving, the car averages 27mpg (or 9Litres/100km... or 11km/litre in the real world) and is sounding like it is pinging ever so slightly
As soon as my scan tool arrives i can check for error codes
Last thing to do is the water pump..... or a 3.5TT engine swap which is probably easier hahahaha
oh and today I am doing a major service including engine oil, trans fluid, diff fluid..... hoping the engine oil swap might help a bit

given that you have flushed the possible rust out. first thing is to change thermostat. after that one needs to see some movement in coolant. if all of that looks good baring any blockages on front of radiator I would be looking then for blown headgasket

My biggest breakthru was stripping the thermostat out of the housing and refitting the housing to the car. If this doesnt make a difference, you can almost pin the fault to the water pump.
or you could try fitting an electric water pump to a custom bottom rad hose and see if that makes a difference before replacing the original......

Make sure you use OEM I had replaced with aftermarket one and still over heated I went to Infiniti paid like 30 and problem fixed! At least did for me and I replaced water pump, fan and couple other things.

basic sedan i love my car just wish it was 5 speed and 2 door. I am about to vinyl wrap it though!
This same issue drove me insane until I replaced thermostat, fan, radiator, and water pump just to find out I had to use the OEM THERMOSTAT! At least I have tons of new parts on it though. Ha
