2018 3500 drw, bought new, 210 K miles. towing a 6 horse trailer, empty or lightly loaded most of the time around the western US. rarely more than 10-11K trailer weight. Coolant goes to 230-235 pretty quickly will get to 240 if not downshifted and keeping up to 22-2500 RPM's, this is with the AC off and the vent fan on high and full heat setting. plenty of power, plenty of throttle if not manually downshifted. I have replaced the thermostat, flushed the coolant, blew out minimal dust, replaced the water pump, hoses, fan clutch tested okay (can hear it howling normally) tow/haul on, or off makes no difference. Trans temp never more than 175..
system held pressure all weekend at the shop. the low coolant light has been on for a few months, coolant level is good, coolant temp issue started before. Any ideas? Im thinking of an aftermarket radiator, maybe original is clogged? this is the 5th or 6th ram Ive had and never had any overheating issues. Thank you for any input!
