Only if your not getting any heat, would your thermostat need to be replaced, as it's in the always open position. My question would be, is the fan spinning, when the car has been driven for awhile and sitting at a stop light or parked in your driveway? If the fan isn't cycling on, the engine will overheat, and could possibly cause the crack to the radiator. Check the fan relay switch as well as the radiator thermal plug. Often on GM vehicles, a small 3 inch brass plug with 1-2 wires has broken off the lead, lost the thermistor inside, or isn't grounded properly anymore.
