I have an '88 XJ that I converted to an open cooling system over the weekend. I installed a new 3 core radiator with a filler neck, '91 thermostat housing with the sensor, omitted the heater control valve, and an overflow bottle. I spliced the old sensor that screwed into the old radiator to the new sensor that screws into the thermostat housing. Now just after start up and the when temp. gauge slightly moves the aux. fan kicks in. I have a 180* thermostat, but the tempurature never comes close to 180* before the fan turns on. I posted this on jeepforum as well and got one suggestion.
