I just finished the AX15,NP231,8.8 install and when I started the enginei i noticed the fan not moving with the engine running. I shut it off and saw the fan rubbing on the lower part of the shroud. When I did the swap out I tucked the belly back up (it had 2"spacers) but I thought it was not big deal because it was going back to stock configuration.
I removed the shroud and noted the fan clutch was parallel to the radiator and about a 1/2 Ito 3/4 inch from the radiator but the fan looked low on the radiator. The mounting looks to be stock but I don't know being family new to jeeps
