REmember these 4.0s don't exactly have a heavy duty radiator stock and don't overheat easily- coming from someone living in the tropics- might source a stock XJ radiator, which is paper thin compared to the A body mopar ones- and they used both and electric and mechanical fan stock. I just thought of the XJ radiator off hand because I just changed one recently- pretty small and neat unit. Looks like it would fit an abody perfect
