phone shows and started overheating. The
stands radiator fan do not kick on while  
sitting  and not sure if they kick on at all

The gist is, your radiator cooling fans aren't working? Check for applicable trouble codes, may be some codes related to cooling fan? Some makes and models, if you turn on the ac, the fan should run, does it? Some, if you unplug the coolant temp sensor, the fan will run all the time, does it? You could use jumpers from your battery to fan for voltage and ground, if good voltage and ground with no fan action, suspect the fan motor is faulty. How hot did the engine get in degrees F?
