Overheating 2007 Chevrolet Malibu Maxx

car was overheating because of a crack in the radiator. Also changed the thermostat and still overheating. No heat coming from the vents.

Ok, so you replaced the radiator and changed the thermostat. Were you able to get all of the air bled out of the system?

That suggests that the cooling system is not full.

Are you sure the thermostat was not put in backwards.

The pellet goes toward the engine…not towards the radiator.
