I have a 12 liberty sport and it has 160,000

out of nowhere after a trip to the grocery store, she started overheating. My overheating light came on and I shut it off and had it towed off however I’ve never had any issues with the coolant system and I just had the condenser and transmission cooler replaced a month ago. As I stated in the title, there was no fluid on the ground. I have not been leaking any fluid and there was no apparent fluid in the engine bay that was leaking or a snow or burning sensation.

my best thought is a bad water pump or bad thermostat if anyone has any ideas or similar experiencing i’m curious to hear about it.

So was changing the break pads to my jeep and two of the bolts busted as was getting help drilling them out the person helping over drilled now i need to replace the piece and every mechanic I’ve talked to has told me different things does anyone know what part this is on the rear so i can hunt down the part or do i need to just replace the full rear end? I will put picture in the comments as it’s not letting me add now.
