There's not a ton to the cooling system Radiator, water pump circulating things, heater core, thermostat, and coolant sensor.

You know what, considering you changed things recently, I'd bet dollars to donuts you just have air in the system. You probably originally had thermostat issue, and in the process of replacing and replacing the upper hose, there's an air bubble in there now reeking havoc. Have you burped that really good? Sometimes it helps to jack up the passenger side a bit, raising the rad cap as high as possible so the air travels up to it once it gets to the rad.

I have a '13 as well, and we do have a bleed valve on the thermostat housing that helps a bit.

I'd only say that any work is only as good as the laborer performing the service. Considering this just takes a pair of pliers, vice grips, or similar, I'd suggest at least loosening that bleed valve and see what comes out. heat the engine up, and unscrew it a bit. If you get bubbles coming out, you have air in there. If it's a steady stream of coolant, you have a different issue. Unfortunately, the bleed valve we have is directly below the throttle body. BUT, it's a plastic screw that is not tight, so you should be able to just grab the sides with pliers or something and turn it to loosen. Here are some pics to show you where -





I can't edit photo on this chromebook, but that second pic you just start to see the screw under the intake boot. It takes all of 5 mins and is free......so it's worth checking yourself.

If the upper hose is physically collapsed you have a plugged radiator, unless the system was not bleed correctly. When cold take off heater hose at top of engine, fill tell coolant comes out reattach hose, loosen bleeder on tstat tell coolant comes out. Start vehicle, set heater to high, blower high and a/c on so fans are on. Keep bleeding system of air thru that bleeder untill hoses are hot and coolant is flowing. Cap and test drive. If possible jack front of vehicle up a foot or so, air is tough to get out of this engine sometimes

One of the fans has a fuse link that is attached to the battery. One time my battery terminal was loose, causing erratic voltages on this fuse link. As a result the Jeep temp rose while sitting at stop lights. The connection was tightened and the problem went away.
