Chrysler Overheats
Unfortunately, it sounds like you may have a blown head gasket and you’ll likely need to take it in to get it repaired or at least do the test yourself.
About your vehicle.
The first thing that you want to do is check the cooling system for any exhaust gases. There is a tester for that, that you can gt from Autozone for about $20. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.

Suppose If you get any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either.
If there are, then there would be an internal engine problem, like a head gasket or head.
Of course, you will want to make sure that the system is full, the coolant is circulating, and the cooling fan(s) are working as well as the pressure cap holding pressure.
Another issue can be water pump worn out or thermostat issue.But if its already replaced and new,Air in the cooling system. Needs to be burped by leaving cap off so it doesn't build up pressure, drive slowly around your neighborhood and take a supply of coolant w/you. Stop periodically and add coolant. When it finally stops accepting coolant fill the reservoir to the line, again drive slowly and recheck coolant level.
Also, is it possible you reversed the thermostat so it is blocking coolant rather than opening and letting coolant circulate?
You could have air in the system. There is a bleeder right near the thermostat housing. You may want to open that bleeder when it is cold, start it and try to get any residual air out of the system by working with that bleeder. The bubbling you see may just be due to the coolant boiling. The lower hose not getting warm at all indicates the thermostat is not opening and there is no circulation.
Some of the symptoms suggest a leaking head gasket. Look for bubbles in the overflow reservoir. If the coolant is cold, you know it's not overheating.
Do not remove the thermostat. In some cases, that will cause overheating because the coolant won't stay in the radiator long enough to cool. More commonly, the engine won't reach operating temperature. Parts won't fit right leading to rapid engine wear, and the fuel system will not go into "closed loop" and fuel mileage will go way down.
The pressure cap simply allows system temperature to go above 212 degrees without causing the water in the coolant to boil. It doesn't CAUSE the temperature to rise.
If Overheating is not repaired on time it can cause many other issue.Also vehicle no start problem can occur.
Engine overheating can cause severe internal damage. Did the engine turn over and not fire, or not turn over at all, as in the engine is locked.
There are a couple of possibilities, the most likely is that your overheating caused damage to the cylinder walls which is now causing low compression, resulting in a no start condition. It is also possible that some other component failed at the same time as the overheating, and that component is causing the no start, i.e., a bad crank sensor or something of that nature. If you let the engine overheat to the point that it began shutting off, then it is extremely likely that you have internal engine damage.
ALSO OVERHEATING CAN BE DUE TO fan not running as the rotating fan assembly is now severely out of balance. This in turn would probably cause the fan motor/bearings to fail, or blow a fuse. If they are damaged/blown then naturally your engine will start to overheat, unless you get air moving over the radiator element by driving it at moderate speed.
