John,

When you turn the bleed knob on the top of the thermostat housing,
coolant (and any air that is trapped) flows up the small tube to the
coolant manifold.  To bleed the system, raise the front end of the van
in the air, open the bleed on the thermostat housing, open the bleed
screw on the radiator and run the engine up to ~2500 rpm, adding
coolant as needed to the expansion tank as the level goes down.  Close
the bleed screw on the radiator once coolant is the only thing coming
out (no air), close the bleed on the thermostat, replace the cap on
the expansion tank and THEN let the engine go to idle.
