Stuck open, missing, or drilled out thermostats are all indications of
prevailing overheating problems. When you get the replacement check that it
does not have any bleeder or bypass opening in the top disc and there should
actually be a rubber seal on the top inner disk. The Vanagon has a lot of
cooling capacity and for cold weather operation the thermostat has to have
no bypass at all for the engine to worm up.

Thanks Scott, et al,

I've got an 87deg thermostat on the way from Bus Depot, so that will go in
soon. I think I've convinced myself that this is either a stuck-open
thermostat, or, more likely missing altogether. Soon as I have the new
thermostat in hand, I'll open the housing and put the new one in. Hopefully
there's no suprises when I open it up.

Thanks for all the advice!
