if you lost almost no coolant you may not have to do this step:

The bleed plug located just forward of the expansion tank and is labeled ENTLUFTUNG (I think you called it the vent screw). Make sure the engine is cool then remove the fill cap form the expansion tank. Loosen the bleed plug and start the car. As it warms up and starts flowing through the radiator air will start coming out the bleed plug. Keep adding coolant to the expansion tank until no more air comes out the bleed plug. DO NOT overfill the expansion tank.
