2010 Pontiac G6 overheats at idle
My 2010 Pontiac G6 GT overheats at idle, normal temp driving at traffic speeds.
Water pump, thermostat, cooling fans, radiator have all been changed but it is
still overheating at idle, why? The mechanics are scratching their heads.
PLEASE HELP. This happens intermittently. It may go a day or two normally
then the next day overheat.
