So I have had this jeep for about a year now and have put multiple hours into fixing it up. I have done some longer trips with it but it has been giving me a lot of issues with heating. It does currently have 32.5" tires on stock gearing which I know doesn't help. But even taking it very easy around town or on the highway it will still kick over the 220 mark and say check gauges (idiot gauge). Sometimes it will hit 260 degrees on hills or if I start to push past 60 mph. I have found that driving in 3 with heat on does help but not very comfortable in the heat. I have had a shop look at it and pressure checked the cooling system with no issues. I am at the point of just wanting to replace the entire motor. It does not boil over when the temp hits 260 which I don't understand with all of the work put into it. The temperature does not seem to be running as high as a temperature gun pointed at the thermostat housing. I inspected the cylinder walls but there might be a pin hole or something I am missing when it starts running hotter. It is a building effect on the heat. Once it starts it does not want to cool down really at all. I will sometimes put the jeep in natural and spin up the rpms to cool it down to the 220 mark.
