Ken;
Just had the EXACT same thing happen to me. It turned out to be
an air bubble in the upper most radiator hose in the engine compartment.
I loosened the clamp at the bleeder (ya right) valve and jammed a screw
driver between the hose and the nipple to release the air.
I, like you, have filled/bled many a Vanagon cooling systems any
never had this problem before.
Drive Safely & Good Luck
