I've seen people here and other places talking about high engine coolant temperatures while towing in hot climates. A little bit of research shows that we have the same radiator in our trucks as the Raptors and other trucks with the 3.5 Ecoboost heavy duty cooling package (part # HL3Z-8005-B). For reference, Ram specs the 1500 Ecodiesel with the radiator used for their 6.4 Hemi 2500/3500 trucks, not the radiator for the 5.7 Hemi 1500 trucks. Diesels tend to make more heat than comparable gasoline engines (higher btu/lbm , fuel, higher cylinder pressures from hotter fuel burn, etc) so it would make sense that diesel trucks should have more cooling capacity than their gasoline counterparts.
Which brings me to an interesting find from my research: Mishimoto makes a radiator upgrade for the 3.5 Ecoboost equipped trucks with the heavy duty cooling package (Performance Aluminum Radiator, fits Ford F-150 2015+). Mishimoto claim:
All good things in my book, especially with the relatively high thermostat opening temperatures for these trucks. Thoughts?

- a 55% increase in surface area over the stock heavy-duty radiator,
- a 45% increase in coolant capacity over the stock heavy-duty radiator, and
- a 63% increase in core volume over the stock heavy-duty radiator.
