Re: engine fan
Your jeep has the hydraulic driven fan setup, isnīt it?
Does it throw any codes? When you remove the temperature sensor connector ( in between the AC compressor and alternator), the fan should go to high speed. If not, the problem can be or the control solenoid, the hydraulic motor, the hydraulic supply or even the coolant temp sensor or PCM.
