I have a 2015 JKU Sport that I just purchased. I knew there was a coolant leak, by the smell. I am getting the radiator replaced & I swapped the thermostat housing & hoses. When taking the top hose off, I noticed a leak behind the tensioner pulley. Apparently, the coolant crossover is the problem. My issue is that it says that the crossover on the Jeep is plastic. The only way to get the "correct" part number is to get the Mopar kit that includes the timing cover & is VERY expensive. There looks to be the same part, but it isn't for the JK's 3.6, for some reason... There is a list of most other Chrysler & Jeep models with the 3.6L, but the part looks to be aluminum. Is there a reason I can't use the aluminum part? Any help is appreciated!!
