This is especially true on taildraggers. It's not impossible (to purge the air) but it is difficult enough that it has caused more than one engine to be overheated to the point of needing an overhaul. The vapor collection point is usually the highest point in the cooling system, the waterpump housing in our case. If you have a higher point in your system, us that. I tapped that connection in my engine as well. Screw a hosebarb adapter into the hole and run the hose to the high point of system. Tracy
