Towing a 3200ish pound camper with the 2014 Jeep Grand Cherokee. 3.6L, 147k miles. On the highway the gauge is between 1/2-5/8. In the mountains it got to 3/4. For reference without a trailer it never moves from 1/3. Not sure of the coolant temp exactly as Jeep decided to not make that a digital readout like oil and transmission.
Oil temp got to 239* towing on the freeway, no hills. Not sure what it was in the mountains as I wasn’t driving it. Transmission seems fine at 204*.
Once I got off the freeway and let it idle the temp went right back down to normal. Which is all the exact opposite of the running warm issues I have with my old ‘96 Jeep.
Nothing blocking the radiator/condenser. It got new radiator hoses and thermostat(s) (I guess it has 2?) and a new OEM radiator in 2018 at about 104k miles. I’ve never had to add coolant, it’s always full in both the radiator and overflow. Electric fan blowing nice and strong.
First 2 pics are of towing flat on the freeway, 3rd pic is after I got home right off the freeway and let it idle for 15 min, the temp gauge went right back to where it has been for years. It’s never really moved from there.
I’ll try to take it out towing with my OBD reader maybe next weekend and get exact coolant temps. Main concern is pulling in the mountains and having a bigger issue.
