After reading XJ cooling threads for the least 3 years I've decided to put my 2 cents in.
I'd like to believe my XJ cooling system is up to OEM standards.
Everything is brand new except for the engine.
Coolant stays green, level never drops, no leaks, ect.
Not using AC, the jeep maintains 220°F as verified by the scangauge (which is about a little past the 210 mark on the dash) 97+ coolant gauges don't read linear. The first tick mark past 210 is actually 245°F in case some didn't realize. I believe that Jeep made this change to the 97+ XJ's to mask the issue slightly.
It was 116°F here yesterday in Phoenix. I was of course using the AC on max and max fan. Coolant temps stabilize around 225-235. Is this normal for extreme heat while using the AC? If I turn the AC off and brave heatstroke the coolant temp drops to about 220 while driving. The car has always been like this. Drives fine.
