You should replace the thermostat first as it may be sticking. If no difference then change the radiator cap as it may not be opening to allow coolant to flow to the overflow reservoir. Also make sure there is nothing blocking the overflow tube or tube connections.
these have no radiator cap everything flows straight to the overflow. there is a good chance just the overflow container is leaking. these years did not have an overflow that could hold the pressure of the system. it is a very common problem for cherokees up to 1991 when the system was revamped
check the cap to make sure its not leaking. a new overflow resevoir is only about 40 dollars at baxters auto parts
