Tempature gauge does not read anything and i dont hear the fan come at all

Check the timing, clean the radiator, check the fans.

fan should kick on around 220 check sensor if it dont

the fans regulator may have gone bad and dont know when to really turn on or how fast to spin as a car gets hotter the compter tells the fans to go faster

YOU MAY HAVE A BLOWER MOTOR GOING BAD OR IS BAD,AN BLOWER REASTAT OR RESISTOR IS BAD

if your talking about the over head temp reading that is an entirely different system.the temps you show at 178,169,173 are all below what they should be,it should have a 195 degree thermostat in that engine,where did you get those temps,if you got them from the dash you should change the temperature sending unit.
re-flashing a computer is done if Chrysler found problems in vehicles and would download the new info to the computer to correct them,

The water is boiling because your car is overheating. Does your tempature gauge read hot or warm? Make sure your coolant level is full. If it is and your vehicle still overheats check to make sure your cooling fan is coming on (fan by radiator) you can do this by just letting your car run and waiting to hear it come on. It should come on before your tempature gauge reads hot. DO NOT let your car run until the temp gauge reads hot. These cars have aluminum cylinder heads and can warp causing serious problems. The cooling fan should come on for a few minutes then shut off and continue to do this. If it stays on, first make sure your A/C is switched off, second if it does not turn off and your temp continues to rise then you have other problems. You may have a bad thermostat, sticking closed. The water pump could be bad or a blocked radiator. If your coolant level is good, your fans are coming on like they should then you might try have your coolant system flushed. Those are some things you can try that are simple and not expensive. If they don't work then you'll have to start looking at other items in the coolant system. Hope that helps, gl.

At around 200^ or little less195^ while driving, ac on idling in traffic will read hotter but out of red, note should change thermo stat if over heated I hope I was Helpfull

Check the cooling fan.

either you have a bad wiring prolem or you need new gadges

did u replace or test tempature sensor for fans it sends signal to turn on fan would change and also thermostat/antifreeze flush would be good maintance make sure u replace temp sensor for fans not gauge most cars have 2 sensors
