It sounds like you've had someone working on this car that doesn't really know what they're doing. Hopefully the engine hasn't been damaged yet but further driving will for sure. Have the car towed to a real shop with qualified Mechanics that can properly diagnose the problem or at the very least fill the cooling system properly.

You have an air pocket in the motor and heater core. When doing anything with the cooling system you MUST use a vacuum fill tool such as an "Airfift Vacuum" tool to refill the cooling system. you will never get the sir pockets out with out one.his applies to Nissan's and Infiniti motors.

Seems that the coolant leaking over the engine which caused the STEAM (not smoke) may have caused some damage or has not been fully cleaned up. It needs a thorough going over.
