Now now yacca-man tearing another person down to lift oneself up.....is a sigh of very low self esteem....try to rise up above that..its the first step to manhood, that shows more etiquette than letting people know what year of XJ I have...I am new here and was just asking a question. And i was not aware of the "search feature".....And as I type I am checking the "search" And i dont se a tread that speaks about if Grand cherokees, towing package fan set up, will fit a XJ, I was not aware that the radiator and what not was set up so much differently. I know from previous up grades that i have done to Chevys and Fords, the Manufactures rely to much on "BEAN" counters to make the finish product. thus a cheaper rig, that can use some upgrades. Once in a while another auto from the same manufacture will run a "heaver duty" line of products, so they may be sometimes interchangeable. thats 'WHY" I ask. So I thought if guys are tearing shrouds apart and doing all kinds different things to put in electric fans, even up to 16", for cooling, could one check out the higher end "GRAND' cherokees that have heavy duty towing and see what I could come up with. Case in point I owned 71 Ford 4x4 3/4 ton which i built a 428 cobra jet, the radiator was not big enough so i found a " high desert cooler" radiator off a 75 1 ton comerical rig. it fit fine, it was a taller radaitor that held a gillion gallions of water. and it cooled the cobra jet down real well. So this was my thinking on the XJ,
