Im asking this for s friend with a 2015, I think I know the answer but I'll ask anyhow. This is at a dealer in NV with overheating issues. Dealer says they have replaced the Thermo, sensors, wp but not sure about the radiator,id have to ask. They claim the overheating or running hot is due to the winch mounted bumper blocking the air flow. I'll also ask what considered normal in 100+ weather temp wise running the A/C? . Seems our 4.0's will run 220 or so and its considered normal. Anybody experiance this with after market bumpers and a winch mounted. Unfortunately I do not know the brand of either the bumper of the winch just to cover the bases entirely.
