Definately make sure it's bled properly. Sounds like it wasn't. Flush is different than bleed, but the mehanic surely SHOULD have bled it.
(lift front of car, heater on full, fill bleed screw) seems to be the trickier points.
Air in the coolant shouldn't create white smoke unless the headgasket blew..With air in the system, your temp guage may not be reading hot air pockets. |
