In this video, I replace the dreaded 2013-2015 6.7 Cummins, dual radiator Y pipe. The plastic Y pipe is prone to failure due to the higher temperatures in the upper radiator hose. The kit I used is the one piece, billet aluminum Y pipe from XDP. The installation is pretty straightforward and can be done without removing the hose assembly from the truck.
