This is a 'minor' situation that can (will) cause big problems; a stuck-open thermostat will increase engine wear like you wouldn't believe - the poor thing never runs at design temperature, rather lt's constantly running as if it has just been started (& please don't ask how I found out, at least it wasn't the Vanagon). Also, thermostats have a bad habit of getting 'lazy', i.e. they open too soon (or actually never completely close when cold) and the engine consequently starts taking a l.o.n.g time to warm up. Keep track of what your gauge is telling you, believe it, & replace the thermostat as soon as it starts getting lazy (cheap,~ $10, & can be done on a Vanagon in ~ 1/2 hour). Austin
