Check for air in the coolant system. It actually isn't hard to remove air bubbles if that is the case. Remove the radiator cap (when cool) and start the engine turn the defroster on fully with the heat all the way up, let it run and circulate the air out as the thermostat opens fully.it The dealer said that 220 is normal "hot" when vehicle is stationary. Should run on average from 189-192 during driving.
