We recently purchased a used 2019 Ram 1500 (5.7 gas) and it seemed to me it was running hot as well. Dealer looked at it said it was normal. Still not satisfied. we towed a small RV trailer (~4,000lb) and on level and light grades it did well. on long steeper grades ( 5-6%) it sucked, 30 mph and being passed by everyone including semis with trailers and it was still hotter ( > 220), than it should be with heater going full bore. Temps based on the digital gauge with outside temps in the 70s. Regular temp gauge doesn't seem to move. Seems to me it should do better than that. ... my questions 1} anyone with similar experience? 2.) any mods I could or should make to improve performance ? 3.) Any driving changes I need to make, such as using the manual gear buttons on the grades? 4.) any diagnostics I could perform on the gauges, fan control, etc?
