Replaced radiator, water pump, thermostat, hoses, etc.. Jeep dealer says that the 1989 model had a problem with air-lock in cooling system (fixed following year) but cannot tell me how to bleed it to get rid of the air-lock problem, thus how do I fix that condition is the question.

And another comment.........
I dont know what year the XJ went from a closed cooling system with a pressurized overflow bottle but if its closed, it needs to be "burped" after the system is drained. You can do this by loosening the temp sensor at the rear of the cylinder head while its running, to allow air to escape. Air in the closed system will cause it to over heat and also make it appear full, but its not.

loosen 1 heater hose at fire wall creating a small coolant leak refill coolant , start engine let it run w\ heater on about 5 min. tighten clamp let engine continue to run until top hose is hot at radiater then shut down cool off recheck coolant you're done. problem was not fixed till 92 my 90 does the same thing.

besides the undeniable fact that your radiator could ought to be rodded or recored if it has too plenty calcification in the water channels. One pointer is to continuously use distilled water fairly of faucet water.
