Since air will always migrate to a high location... I'm wondering how
bleeding air with the rear raised will get air out of the upper reaches of
the radiator? or the heater core? .... seems like air trapped in these
places would have to go down (to the hoses that run under the van to the
rear) before it could then go up to the pressure tank... an unlikely route?
