Thanks Dennis. I fixed the symptom when I found a weak spring clamp at the
coolant distribution tower. Now I can fix the cause.

Every week or so the Vanagon would burp out a cup or two of coolant, no
dripping otherwise. I'm guessing that the cap occasionally failed to open
to the overflow tank.

Thanks again for your reply.
