What did you do to your jeep today?

Renegade overheated today…
Did a little diagnosing and found that the radiator fan wasn’t working.
I have a spare rad fan but that one is a 3 pin. The parts yards is selling the rad fan as much as a new one from rockauto guess it’s time to order one.
I hope the overheating didn’t bother the engine too much. 203087 is my current mileage.

I would play around with the 3 pin and see if I can make it work. In computer fans (very different, I know) a third wire is usually for remote on/off or a PWM signal to control the speed. With 12 volts to the red wire and the third wire, and black to ground, you may essentially have a working 2-pin fan. You could swap the connectors.

I am not saying to do this, just experiment on the workbench with a 12 volt battery and see if the 3-pin fan works the way you think.
