Jeff,

How right you are and running the 80� thermostat is only treating the 
symptom.  In my experience, the first thing to do on a Vanagon with a 
temperature gauge which is riding high is to check for a pressure leak in the 
coolant system.  The smallest leak can cause a big swing in coolant 
temperature.  For anyone who wants to see the manifestation of this, glue a 
cat's whisker to the seat of either relief valve in the pressure cap.  Then, 
take a run down the freeway.  When you finally stop, you will see the 
temperature gauge peg out and the expansion tank puke like a sorority girl 
during spring break.
