that's just about exactly what my 1988 kept doing. when i replaced (after much
suffering at the hands of several dealers) the temp coolant sensor (about $30)
the problem went away.  then, about a year later, it did it again. replaced
the sensor again, and the problem went away again. hasn't come back (yet),
but i have a spare sensor now!

nope. dealers do NOT seem to have anybody or anything to work on vanagons
with the water-cooled engines. either they don't feel they can make enough
money off us to pay for the equipment, or they don't want to bother training
anybody these days.  so it's basically swapping parts and hoping.  so far,
that's got me by. :(
