1- new water pump
2- new thermostat with a temp of 165

Did you replace the hoses? I've read on here that a few guys replaced their hoses and the new ones didn't have the coiled up metal inside them. When they would accelerate the hose would actually collapse and not let the coolant flow. Worth a shot. Hopefully it's not a head gasket.

What temps does it reach when overheating and under what conditions -- idling, highway, trail, always.

Have you checked clutch on mechanical fan? Is aux fan working?

You mention rad flush, I assume you did a complete heavy duty flush for complete system.

Assume new 16# rad cap?

The XJ 4.0 is designed for a 195* thermostat. As you have learned, the tstat designated temperature has virtually no effect on overheating. The designated tstat temp determines when the thermostat opens and after it opens, other factors control the operating temp of the system.

make sure there is no air trapped in the coolant system.
