Car was getting hot then cooling back down, while getting hot heater would not work. Took to mechanic, had thermostat and water pump replaced. Car ran fine for a couple of days, then same problem. Took back to mechanic. He said its possible the thermostat purchased was defective. Installed new thermostat from the dealership. Got in car did not get hot and cool back down it got to normal operating temperature and heater worked. Three days later, car started getting hot, cooling back down and bubbling the water out of the overflow reservoir. There are no leaks anywhere, no blown gasket, or cracks. This problem is becoming a big pain. I think it is a defect caused by manufacturer and if the problem cant be fixed, I know ill never own another GM {great mistake} vehicle again.
