Cooling system bleed
 

2007 hyundai santa fe.
is there a plug / screw that you bleed the cooling system.
did fill the radiator and system with coolant.
But air bubbles keep cumming out of radator.

You don't state why you had to add coolant. Where did it go? Did you do work on the engine where coolant was allowed to leak out?
Once we know this we might be able to offer a means to help get the air out.
Sometimes a defective water pump seal will allow air to be drawn in when the engine is running while there is negative pressure at the pump shaft.

I thought you just run the engine for about thirty minutes with the cap off and keep refilling until all bubbles stop
Also, fill the overflow bottle to the hot level. Close radiator cap.
When engine cools, it should draw coolant from the overflow bottle and drop it to minimum level.
