Well at 76k I guess I should change the belt and idlers. Everything still looks good but ya never know. What are you guys running and does anyone have any experience with a German company called Flennor? Seems they make an EPDM rubber serpentine for the 4.7.
I just bought a gatorback as a spare for the WJ, the Mopar belt the dealer put on when I bought it seems to be ok but I like keeping a spare around for something inexpensive but potentially deadly, with the hydraulic fan I think this engine would overheat even faster than any other without a belt. Had good luck with Goodyear and Gates belts before, I think they are all I've used.
