Engine Cooling problem
1992 BMW 735 6 cyl Two Wheel Drive Automatic 210000 miles

THE ENGINE OVERHEATED WHILE DRIVING. INSPECTION REVEALED A LEAKY RADIATOR. IT AND THE THERMOSTAT WERE REPLACED. AFTER ADDING COOLANT THE ENGINE IS STILL OVERHEATING, IT APPEARS THERE IS AIR IN THE LINE. I OPENED THE BLEEDER SCREW TO ALLOW IT TO ESCAPE AND START A STEADY TRICKLE OF COOLANT. BUT I AM STILL GETTING AIR AND IT IS STILL OVERHEATING. HOW DO I GET THE AIR OUT OF THE SYSTEM?THE COOLANT DOES NOT APPEAR TO BE CIRCULATING

There is a bypass hose from the radiator up to the expansion tank, if it is clogged, you will not get all the air out.
