LOL, that is the same valve that is opened when you turn your HVAC controls to hot. You MUST turn your heat to hot when bleeding the system. You can keep the blower off but the temp selector should be all the way to HOT. If air keeps comming out of the radiator cap and bleeder valve, just keep adding coolant. Unless you have a massive leak, it just isn't done burping yet.

Sounds like you are doing everything right except for the HVAC controls.
