The Ford does have a significantly larger cooling system than Ram, as well, the Ford is a little more fuel efficient (more of the fuel's energy is being harnessed to do usable work which puts a little less demand on the cooling system) so it should outperform the Cummins on a hot day. It would be interesting to see.
I know my 15's cooling system is not as large as the newer RAM's but towing 35k up long 6% grades in 90 degree weather nothing ever gets close to being hot.
It would be interesting to see all three towing on HOT days for sure.
The coolant capacity of the ‘21 Ram is very similar to that of your ‘15 …. about 22 quarts. Are you aware of anything in particular that Ram has changed, as far as the cooling system goes, in the new trucks?
I do know the grill opening is larger on the 19's and up. I thought I read it was a larger system. Maybe same capacity but larger surface area???
