WJ is running again. Replacement radiator is all good. Left the front plastic off, still waiting for my behind the grill cube lights to show up. Amazon is a week late.
Fired it up, bleed the coolant system, and adjusted the electric fan controller all with success. With the probe moved to the hot side the controller works like a champ.
But...... the new electric fan assembly has so much vibration you hear a low drum inside the vehicle and can feel it from the seat. Can't risk it shaking my radiator to pieces. So out it will come and I will replace it with the high mile junkyard MOPAR electric fan I have in reserve.
So that makes 2 water pumps, 2 radiators, 2 fan controllers, and 2 electric fan assemblies to get acceptable parts to finish this project.
Edit: on a WJ, spray the bottom few inches of the radiator black, and it will hide with the AC condenser when you put the plastic bumper back on. No aluminum bar visible side to side through the lower airflow slats.
Edit: Checked Amazon again, they pushed the KC LEDs out until the 21st. Thanks for the notice guys. Cancelled Amazon and ordered direct from KC. I should have the lights Fri or Sat so I can keep going on this project. The 4x4 Fabworks brackets are already here.
