XJ coolant system redo

Most of the parts you need are available from the dealer and/or salvage yard:

twaldr> Does someone have a kit or sell parts to replace the odd closed coolant

I did the swap on my 88. Man what an improvement. I replaced the radiator and heater control valve. It was a joy throwing out the old plastic pressurized overflow bottle. KH

I did this on my 88xj two years ago. new 93 or later xj 3core radiator with water fill cap. 190.00 auto zone new heater control valve 16.00 napa or others. eliminate the coolant system container and run heater hoses same route, but not into old coolant cotainer. good time to add an overflow jug. 9.00 auto zone I aso had to use a newer style thermounit for the fan. works great and the old breakable closed system was always cracking.
