A better option than any bleed screw is getting a no spill funnel bleeder that goes on the radiator and becomes the high point in the system. Park on ramps or a slight incline, fill with coolant and let it get to operating temp with the heater on max. Gets all the air out without spilling and wasting coolant out of a bleeder. If you don't wanna order on Amazon any auto parts store will have the same thing in the tool aisle.
