I have a 1990 xj 4.0 I have bought a 3 core replacment. I have everything I need. I think. I have a problem. This rad. Doesn't have a electric fan switch spot for it. And I dong want to direct wire the fan. Someone said I can get a temperature sensor adapter that plugs into the radiator hose. That will except the elf tric fan switch sensor. But I haven't found one. Can any one help me with a idea or help. I'd appreciate it.

 

The ones that use the probe you place in the hose are garbage. It WILL leak. There are electronic ones at Autozone or Advance the has a probe you carefully push through the rad fins.
Look this up on Autozone.......Part Number: 733647

 

Thanks. I got a idea. I took the old rad. And née one down to a rad. Shop. They pulled the old bung for the elect. Fan temp. Sensor and installed and soderd into the new rad. They didn't charge nothing. Good company

 

Update: today our running around the 3 core wad doing well. Around noon the jeep started heating up. 190, 210. Around twelve thirty it hit 230 climbing to 260. I start noticing radiator fluid on the ground. I went and got a 180 degree therm. And gasket. Just before I installed I turned over the motor. Water pump is working. Put on new term. Had a emergency. About a hour later jeep is climbing to 210, 230, 260. Pulled over let cool. My electric fan is good and working. Also fan clutch is good and working. I have already assured there is no air pockets. Any ideas what I did wrong, missed, or suggestions to help?
Thanks
