Someone has finally come through with a 2 row radiator for 2012 up Durangos and Grand Cherokees. I asked Mishimoto about this at LS Fest and was told that one was in the works. I checked the website recently and it's there along with an installation video into a Grand Cherokee SRT. I don't really have many miles on mine but noticed that the factory 203° thermostat runs as low as 199° sometimes. It would be nice to be able to hold that temp most of the time. Towing in hot weather must really drive that temp up with the factory 1 row unit.
