Cooling system flush, new t-stat (OEM 190-195 deg), new cap and posibly new reservoir. It runs a closed system, so if you can afford to switch get a rad for a later model XJ with an Open cooling system, new overflow tank and new upper rad hose.
Def check for coolant in oil and any other problems you may have. Also, check water pump, mech fan/clutch and sensors and your electric fan.
