Climbing over the Rockies

Down shift and watch your temps. I go west every year to visit family. The mountains are taller but the grades are more gentle for the most part. We have 6or 7 and sometimes even 10 percent but only for a couple miles while you have longer stretches and higher altitudes out west. That means the radiator is getting less air across it at high altitude. The turbo will cram air in to the engine till you are about 10k feet and higher then that the engine will start to make less power but the heat will continues to increase. So gear down and watch the temps and have a great trip. Not is not a huge issue to slow down climbing either and only go 45 if that keeps the temps down. I know I pulled out of Rapid City and hit the mountains and it was 110 that day. Two DPs were on the side of the road overheated. I know I kept my engine temps down and had no issue. Did the same trip a few months later at 45 degrees and hammered up the mountain at full throttle.
