All ActivityMost RecentMost LikesSolutionsCoolersI have a 07 2500 Ram with a 5.9 Cummins. There appears to be 4 coolers in front. Coolent radiator closest to engine, then the condensor for the AC, but what are the other two. I was going to put a trans coolere on but if one of these is already a trans cooler do I need another one. The coolers all appear to be pretty big. I tow a TT of about 6,000 lbs..Thanks for any help you may give me. RonNN
