The bleeder valve and nipple on the top of the thermostat housing run to the side nipple of the coolant expansion tank on the rear firewall, not to the cap. If there is a rubber or clear hose coming out of the top left side of the coolant bottle, put the other end on that nipple.

That smaller nipple is a vacuum line. I can't tell you where it goes exactly, but there should be a vacuum line diagram on the bottom of the engine lid.
