Car continues to overheat after thermostat and water pump change. Any suggestions?

Chances are you have cracked the head or have a blown head gasket.A hot engine does not like cold water added.Once a car has overheated once or twice it's too late to change a hose or water pump or thermostat.If motor has a misfire now or bubbles flying out overflow or radiator cap it's done and being a Chevy Cruise, it's not worth fixing really.
