quick update, jeep is still not overheating. new radiator is working. I took it through a slow drive through on a very hot day (100 degrees) and it slowly got to about 222, but quickly down to 210 after moving. No boiling sound when i stop.
peopenn.. how about other components?
entire coolant system: can you pressure test to make sure there are no leaks
heater core: is it clogged up, can you flush or bypass for testing
thermostat: is it working, you can replace or remove for testing
lower hose: does it have the spring in it? is it collapsing under pressure
radiator cap: you can replace or have it tested
water pump: is it failing? usually leaks through weep hole
ac condenser: is it clogged with mud and bugs
assuming your radiator and head is sealed correctly Im not sure what else you can check
