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.

Re: engine fan
Cheers guys for that i will try those options, to clarify the fan does the same speed while at idle with a/c on or off, if itry sand driving the temp gauge goes through the roof. regards pete.

Re: engine fan
Hi, yes the fan has done the same speed since the day i bought it, i have only just realised that its two stage as soon as i tow or do any sand driving the engine temp goes straight up, with a/c on as well, regards pete
