Overheating question...Help?

Autos are known to overheat anyway. Many including myself have installed aftermarket trans coolers in front of the radiator. Some higher end models have fans built into them but I don't think they are necessary unless you live in the desert.

Or.....?Second we use a ford tarus fan any junk yard look for a fan in good shape. Some guys wire it up to the A/C so when you have it on its running. Some others have wired a switch to turn it on manually. A few have even added on thermo switches

Buy or borrow an infrared thermometer and point it at the base of the thermostat housing before it overheats, then again when it overheats. That will tell you if the engine is in fact overheating.
Can you hear the fan coming on?
Have you ever had the JK in deep water? That may plug the radiator fins.
Find out if it's actually overheating, then troubleshoot from there.

With the engine running and the JK not moving, the temp will climb to 215°F. That's when the fan will come on, lowering the temp to somewhere around 195°F, where it will shut off until it reaches 215°F again.

Ok well I sprayed it again and it looks to be running clear from all the nooks n crannies I could get into. Took it for a drive up the highway and around town. The temp gauge is very very slightly over where in normally is. Like a half a bar higher. Not bad at all.
I'm just hoping that's all it was. We'll see in the next few days if it's good to go for good. Thanks for the help from those who gave me hints.

Hopefully I wont have to do this! But I was thinking about it.
