Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
If you open the hood when the car is running hot, do you hear or see the fans running? Might be a fan or the thermo switch that activates them. If the cooling system has been bleed properly, the fans and thermo switch are the only remaining probabilities.
Sorry, I didn't see that you posted about the fans working fine. In that case. The blades might be missing off of the water pump due to cavitation o the wrong thermostat may be installed. I think it is very likely, from the information given, that you still have air in the system. You might want to have another mechanic pressure bleed the cooling system jut to ensure the system is air free.
