Just to clarify, fill the radiator expansion tank via the filler hole NOT the bleed hole. The bleed hole is for air to escape, although you will see coolant flowing out of it once the expansion tank is full. Continue filling until a steady stream of coolant is coming from the BLEED HOLE with no air bubbles.
