Dave,
Seems that the building full of engineers who designed the Vanagon could
have easily chosen a 10 degree cooler thermostat. Unless you can find a
really good reason to change from original specifications I would suggest
not changing. As I understand it, there is an optimum engine operating
temperature... below that is not so good for the engine... cooler is not
always better.
