i have a 89 xj 4.0 automatic and was wondering how hot does it have to get before the electric fan will kick in? :confused0006: the gauge has never really gone past the halfway mark (straight up) and i have never seen heard the electric fan come on. i did check the fan by wiring straight to the battery and i does work so....... any one know if it has to be much higher or ......? i'm not sure if the temp sensor for it is working so not sure if i should just wire it to a switch like so many others do i would rather not if not needed.thanks in advance for any help :)
