Angry 02 300M 3.5L HO-OverHeating

I have a 2002 300M 3.5L HO the other day it over heated to the red...I didn't notice till it set a code and dinged...
Luckily I was less than a half block from home...when I opened the hood ...I discovered a crack in the tank reservoir
spraying coolant...I got a replacement online changed it out and added some universal coolant less than half a gallon!
I did open the bleed valve while adding coolant it was a steady flow no bubbles, but now the car overheats under driving conditions very fast 10-15 minutes it's fine idling but driving it goes up past half quickly but if I crank the heat it comes back down to half, is there another issue or just air in the system
