- 2015 Ram 1500 Ecodiesel
The cooling gurus discovered that swapping grilles on the 2014 - 2019 Ram trucks made a big difference in cooling. Some grille styles had larger openings and flowed more air to the radiator compared to other styles. So, sometimes small modifications can achieve big gains.
I've found that the third gen diesel engines run much cooler than the second gen engines, at least in the Ram 1500. I can benefit from the winter front cover on my 2020 when temps hit 30*F and below for best fuel economy. I don't need a winter front on my 2015 until temps get down below 15*F. One reason why the tow rating is so much higher on the 2020 trucks is because it can handle the heat. The 2014 - 2019 trucks were limited by heat. Ram also opened up the grille a lot more on the 2020+ trucks and relocated the intercooler.
