Take top plate off radiator area and check between the radiator and the AC condensor. This area will fill up with leaves and so forth and block air flow. Take a garden hose and spray out the radiator from back to front as good as you can. Brush off front of AC condensor. If no help, take off radiator cap, drain down coolant a couple inches, start engine, look for good circulation from cores when engine gets hot.

 

radiator is clean and so is condenser the car will never overheat ideling but once u start driving it will overheat

 

Air dam in place?

 

IM GOING TO CHECK IT TODAY AFTER WORK
