Jeep runs a tiny bit warm going up long mountain passes on 32" tires, not even to the first mark after the desired (210°) running temperature.
Seems like there's something wrong with my cooling fan.
It seems to engage and disengage very frequently idling. Obviously can't really tell when I'm moving when it's turning on, or if it is.
I have flushed my radiator twice(someone mixed dexcool and green before I owned it) in the last year and just installed a new thermostat with a flush a few days ago, the Jeep is staying a touch cooler, but still not staying on that 210° mark if I'm pushing the Jeep uphill in second and third gear for 20+ minutes.
I'm starting to think that fan or the clutch for it is malfunctioning?
Anyone have a similar issue that might be able to point me in the proper direction(hopefully at a pull yard - I just sunk entirely too much money into this thing in the last couple of months addressing issues for wheeling this summer)
Am I too worried about it? Is it okay for a 4.0 to get a little warm going uphill for extended periods of time? It will not completely overheat. It never has. The hottest it ever got was just barely to the next hash mark after 210.
I figured if I let this continue I'd risk damaging the head?
Thanks in advance.
Jeep also has a full exhaust system(from the header to the tailpipe) and a K&N cold air intake.
