The white smoke is an indicator that the car needs a headgasket replaced. Coolant gets into the combustion chamber and burns white. This is most likely causing the car to overheat.
Have the engine checked for a bad headgasket. If I'm wrong and it's fine, let me know and I'll walk you through how to identify the problem.
I hope this helps.
