Tim,
Try a new coolant tank cap.  They only cost about $10.00 and over time the valve inside ages and does not let excess coolant and pressure get to the overflow tank.  This is just speculation but I think that some of the other problems with the coolant system in these vans is caused by excess pressure from old caps.  Our van went through two rubber head gaskets, (one on each side) when we fixed the second one we changed the cap and have had no problems since (knock on wood).
