This is on my 2013 ram 2500 with 6.7 cummins. For month's I have been looking for a coolant leak. The dealer has looked a time or too as well. (very minor) but I could smell coolant all of the time. I had pretty much decided this was an issue with the EGR cooler which was replace less than a year ago. (which is still under warrant) so I asked them to check it out. They came back and said they see that the upper rad hose has a leak and needed to be replace. (I should have asked how much).... Parts were about $150 and labor was 2.5 hours at $130 per hour. My question is, "is it really a 2.5 hour job to change a radiator hose?
