Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,When you replaced the thermostat did you bleed the cooling system on refill?
The problem you are describing sounds like you may still dealing with trapped air and that can cause regular flow through the system. This engine can be a bit of a pin to refill and get all the air out. I would start first with rechecking to see if you got it bled properly and the system is full. I have enclosed the steps in the link below as well as the bleeder valve location. Recheck this first and let me know the results and we can work from there.

None of these parts will cause the engine to overheat, if you are sure you are not dealing with any trapped air and you still overheating and getting bubbles then the next steps would be to perform a block test to check and see if you have a blown head gasket.
Its sure pointing towards a head gasket.
