Perhaps I'm mistaken but I believe I have read on here in a few threads that it's typical for a 230 reading while running the ac... I experienced that when it's 75+ degrees outside in nearly every vehicle I have owned with the exception of the delivery van I drive which sits at about 215 with ac on....

Agreed except with a thermostat that opens at 160, I would expect to run low. Not the case. I am going to change out the mechanical fan for an electric one. I'm sure that will help some but that is not going to be a solution as to why she is doing this.

The electric fan swap should help it out alot I would think... I believe a good electric has more cfm and you won't have any drag from it... But keep in mind that even if you had a 190 stat in there it would more than likely run at the same temp it's at now from what I understand... Either 160 or 190 are both gonna be wide open at 230 degrees so the fact that it's opening sooner is moot...

Infbob! You are indeed correct bud! 160 or 190 if I'm up at 230 it doesn't matter cuz they wide open as you pointed out. The electric fan swap will help in that it is mor CFM and like you said the drag goes away! I'm just surprised that it wants to go as high as 230s 240s despite everything I have done! I'm not even sure that the shop will figure it out. I have taken care of my jeep since inception and has never been abused. It should have not any reason to blow a head gasket!

Got a combustion test kit? If not maybe the local schucks has one they could lend you? That way your never second guessing if it's bad or not

Yeah I'm affraid what it's gonna show. I did borrow one from auto zone yesterday and tried it. I flipped the bulb and it sucked in coolant so that test was a bust. Cleaned it out and tried it again and this time it was sucking in air but no color change to yellow. So, I'm not sure if I should call that a false negative or trust it.

Ha just try pumping it every minute for 15 minutes and then go have a beer to celebrate if it don't change color... Or if it does have several beers to get the desire to pull your head

Makes you feel any better my gauge started acting funny again... Back to the fun time of being 30 degrees hotter than the actual temp... There must be a short somewhere messing up the sender... There is always something that just don't want to be fixed despite the effort put into fixing it...

Am considering dumping the stock gauge putting in an aftermarket kit and setting up a toggle switch to control the e fan

I had similar issues, replaced entire cooling system at a campground on a wheeling trip. Only thing i didnt replace was the fan clutch because it felt tight enough. Figured out later that when the fan clutch got hot it loosened up big time. Actually took it to a mechanic (first time for the jeep). He couldnt fugure it out either, lol.

Is your lower hose collapsing?
Thats all i can think besides head gasket

X-Rated: hey man I haven't thought about that. I replaced the lower hose about a year ago. I remember the OE had a spring in it. But the replacement did not. May be there is something there bro! But that's gonna mean going to the dealer. Like Infobob, Jeep and I are allergic to dealers and mechanics. Once They wanted $1500 duckies to replace my tranny solenoids. I bought the solenoids for $207 and did it myself in 1hr. Suck it!

I simply went to the hardware store, bought a spool of wire and "borrowed" a piece of pvc pipe about the diameter of the hose and wrapped the wire around it making the spring right there in the store.
Getting it into the hise was a battle but i cant collapse the hose by hand so im guessing its all good.

Im not even sure dealers sell the springs anymore.
New hoses are supposed to be stiffer but they sure dont feel like it so i made the spring.
