Hi all!  My 86 Vanagon, Stella, has recently regained consciousness (her
transmission was rebuilt).  Anyway, I've noticed that the warning light
for the coolant has been staying on after I start her up.  The problem
usually resolves itself after I turn her off, and restart.  I have
checked the coolant levels, and all is fine.  I had the sensor replaced
in March or so.  Any suggestions on why this crazy little light is
pestering me?

Peace, Love, and Granola
