So I think I found out why RAM started installing electric supplemental heaters in their trucks for "free" starting in 2019...the engine doesn't warm up, nor stay warmed up, as well.
The much larger radiator in the 2019 needed to cool the higher output creates an overcooling situation. I would have thought the grille shutters would solve the problem, but apparently not.
It was 0F this morning, not extremely cold, but cold. I drove 25 minutes on mostly 50 mph roads without much in the way of hills...and noticed when I got to my destination the reported coolant temp was only about 170F. Oil temp (whether accurate or not) was even less at 150F.
The heat was fine, but I suspect the supplemental electric heater was working the whole time.
I drove this same route in my 2018 many times with the coolant reaching 190 very quickly.
Anyone else in the cold weather noticing this?
Can you post up what the total cooling system capacity is on your 2019?
My 2018 was 5.7 gallons.....going off memory.
