Running hot

[KevyLuv]

I have a 2015 JKU that the engine temp constantly runs 245+ At highway speeds. Before this the Jeep had a bad thermostat that has been replaced twice now. The increase in coolant temp started after the replacement. I have also had the radiator replaced with an OEM replacement and a new engine dropped in and still running close to 250. I have not boiled over yet and I definitely don’t want to. This engine is a 3.6 liter V6. In order to bring the temps down I turn on the heater full blast. City streets the Jeep runs at 222-240 with A/C on. I did check my fan clutch and the fan spins with no resistance when off and engine cold. Any thoughts? I’m a little frustrated at this point. Jeep has a winch and aftermarket bumper. Mechanic removed winch and bumper to test and found no change in temps.

You may have more luck over at the JK forums, hopefully some former JK owners here chime in with info.

Fan clutch? Wtf

on a more serious note, how muddy do you get it? How much dirt and bird feathers are stuck in your condenser?
does your A/C performance suck?

Are you ever losing any coolant?

Is your belt routed correctly over the water pump?

do your oil temperatures closely correlate with coolant temperature?
