Jeep overheating

I have a 2007 Jeep Unlimited Sahara 4 door with 39000 miles , the other day when picking up my son I left jeep running for about 5 to 10 minutes in mid 80 degree weather , when I got back in temp was hot , needless to say let everything cool down , started and drove home with heater on just in case . Once I got home I let the Jeep run for about 30 minutes with AC on and it never overheated , I moved aroung wiring going to cooling fan nothing happened . The onlything is my fan is making a wierd noise it never made before , could it be going out ?? Anyone else had this issue???? And whats crazy is how they changed the fans from the 07s the 08 09s have differnent ones , anyone know why?????????

Bump, I have been having some overheating issues as well, mainly when parked idling. I think that my problem is one of two things, 1. My xhd bumper is not properly blocking mud and debri from the back of my radiator and fan like the stock bumper and fairing do, or 2. The superchips flashpaq isnt allowing the engine fan to operate correctly when using a performance tune. Can any experts chime in on this??

Always start with the obvious. Have you checked you coolant level? Where is your temperature gauge when you are overheating?

In your case, is the fan operating normally? I'm certainly no expert but I had a number of cooling issues with my last car, so my first three checks were 1) coolant level (leak?), 2) fan operation, and 3) thermostat.

If you have things INHIBITING the air flow to the radiator, if you've been in mud, If the "flashpac" has altered the fan op. for temp increases--

Do what these guys have suggested previously, but

If your grill is subjected to what I suggested above--it's wrong position mods !!

It's always gonna heatup in warm temp with idle or low speed !!

Good luck

Could be:
Bad thermostat.
Bad fan (bad bearings will make it run slower and the heat only increases the wear)
And of course coolant level but assume that's the first think you checked.

If none of the above check to see the temp your fan should come on and verify with an infra-red gun/heat sensor by pointing it at the radiator. These guns are now very cheap and a great tool to have anyway.
Last possibility is the water pump

Coolant is full and red , and i guess i dont understand the second part, my temperature gauge is in the red when i am overheating??? My fan is working properly, but its almost like it doesnt want to kick on until i am quite a ways past half on the gauge, also, my winch shouldnt be inhibiting the airflow, and i cleaned out my radiator area and it wasnt that dirty. I am thinking the culprit is either the flashpaq or the temperature sensor.

Unless it started doing it as soon as you started using the flashpaq that probably isn't it. Ever find out what the funny sound coming from your fan was?

My tj overheated once. It was the fan relay. Changed that and it was ok.

Things like that are much tougher to diagnose these days. In the old days if your fan belt was intact and your fluid was filled, it was your thermostat.

Very true, when i had my land rover at 180k it started periodically overheating, i replaced everything under the hood and it ended up that the head gasket where shot and engine heat was somehow mixing with the cooling system and it was overheating. Needless to say i sold that dude when i found evidence of coolant in my crankcase haha. She was a good rig though.

Having a slight cooling issue as well on my 09 JK. Started heating a bit at low speeds and fan seemed to delay coming on until the gauge was 3/4 up. Also the gauge would move faster than normal. Changed the thermostat ans seemed to help a little. Bought the temp sensor gauge too. Anyone know exactly where it is located? Looked like right up front but the unit is not the same. Double checked with Chrysler and it appears to be the correct sensor but can't find it anywhere on the engine. Thinking it might be near the rear and hidden some?
