The main mistake people make with the Renix cooling system is not "burping"/purging it properly. A clean, properly maintained system is adequate enough. Also DO NOT crank down with herculean strength on the expansion tank cap, this is another mistake most make.

I don't have time to read this entire thread but I upgraded to a radiator from a 94 XJ and changed the thermostat housing along with the heater valve. Ran cooler ever since. I kept the pressure bottle as a reserve over flow tank.

I ditched the plastic for aluminum,I have not had a problem with my closed system yet.
I do have a bleeder hole on the upper rad hose and 91+ thermostat housing.
