It sounds like you did not bleed the coolant system properly.
With the engine cool, remove the rad cap and top up the coolant. Leave the cap off and start the vehicle with the heat on full. Let the vehicle idle until the thermostat opens up (so until both hoses are the same temperature) and you get heat coming out of the vents. Once this happens, usually all the coolant is bled out of the system.
Keep in mind as the vehicle is running the coolant level will get lower and lower since the air pockets are escaping, keep on refilling the radiator to the top.
