So how do you guys with bigger tires, heavier Jeeps, keep from overheating near 4000 rpms when you need it? JK 2013 2 door. I replaced entire cooling system and put in a very expensive Mishimoto V2 radiator. Cooling system flushed, thermostat replaced 2 times, new water pump, etc. I live in WNC Mountains and when I go up a high pass and hit 3500 rpms or more, overheats every time. I have 3 inch lift with 35 inch KM3s. So I am not as big or heavy as those guys with bigger tires and 4 doors. No vents in my hood and I do have fender well covers on. Next thing we are going to try is removing the hood and do some testing. Doing that before cutting up the hood to maybe reduce heat. I have 4.56 gear set. Thanks!

Before you yank the hood off, try turning your heat on, have it blowing on the windshield and turn the blower on to whatever speed you want.

Can we get a little more info? Like, is it a manual transmission, is it typically in 4WD, etc.
When you say overheating, is it blowing steam, or is the temp gauge climbing? Is the fan kicking into high speed?
When you upgraded the radiator, did you also upgrade the fan?
