i have an 06 charger with 160,000 miles on it, the thermostat housing sprung a leak and before i knew it, it over heated to the point where i had to wait an half hour to let it cool down, before the motor would even turn over. long story short, i topped it back off and it kept over heating, i thought it was a head gasket, before a friend enlightened me to the fact that you need to bleed the cooling system,i consider my self a car guy, but bleeding a cooling system was new to me, so i'll ask, did he bleed the cooling system? My charger still runs like new. and it got hot
