Bad fan clutch?
2002 TJ 4.0L
Things I have replaced within the past 6 months:
Thermostat & Housing
Radiator Full Flush
I spent the past week at silver lake sand dunes here in MI and all went well the entire trip until the last day. I noticed that when at idle or low speeds the temp needle will spike to about 220 or so. Before the dunes, she wasnt having any overheating issues at all.
Today when I drove to work on the freeway for work 25 miles it didnt spike over 210 at all. However once I got off the freeway and came to stop lights, it started to jump. I also started to hear a minor squeaking noise coming from under the hood that increased with rpms. When I parked the jeep, I popped the hood and with the engine off and hot, spun the fan with the hand to find that it had little to no resistance and spun freely.
I am assuming it must be the fan clutch but I just want to make sure before I go and replace it. The only two things I havent replaced in the cooling system in the past 3 years I have owned the Jeep is the water pump and the fan clutch.
Also how difficult it is to replace if that ends up being the issue.

Does sound like a clutch that is not engaging. It's pretty straight forward to change, big ass crescent wrench (no idea the actual wrench size) on the inside of the fan. Keep the belt on and turn it off like a screw. You may have to stick something between the fan blades to keep the pump from turning.
Youtube has a lot of videos on changing one
