My car overheated yesterday. Took it to a mechanic who changed the thermostat and flushed the radiator.?

Within an hour of picking up the car, it overheated again and all the coolant spilled out from under the car. There was no white smoke coming from the tailpipe, no bubbling over in the engine, no white milky stuff on the oil stick - so what could be the problem? Help please!

could be that the mech did not purge the system after he made the repairs

Take it back right away, its not fixed obviously. It should be under warranty for the work that they did.
WHAT KIND OF CAR ? WHAT YEAR ? WHAT ENGINE ? REGULAR FAN OR ELECTRIC FAN ? ALL THIS WOULD BE HELP-FULL
it could be that the mechanic did not replace the gaskets after he replaced the thermostat. check for leaks off the sides of the coolant pipes.
