Hey guys, just reaching out before I start spending some money. I have a 2nd gen dodge 5speed 3.73 gears with mild build. I recently bought a 37’ toy hauler that weighs close to 9,000lbs empty. I live in Colorado and when I tow this thing is usually over some pretty serious passes. As summer is here I’m struggling keeping my engine temps under control. I do have a high flow water pump, new oem replacement radiator and 190* thermostat. While pulling up RIO with my RZR in the trailer I got a little out of control on my temps. Probably 225*. My EGTs were getting a little hot at about 1250. My truck was getting hotter sooner with my antifreeze/water ration about 70/30. I took some advice from my father who ran heavy duty diesels for 20plus years and am running 25/75. As he said it will still get hot but not as quick. He was right. Anyone done anything to their truck to keep the temps down that actually worked while pulling heavy? I’m guessimg my truck and trailer combo was close to 24,000lbs when loaded.
