OK, it's the wee hours after mid-night here - and I can't sleep - so I'm
thinking up things about Vanagons.

I've got a coolant level sensor light that comes on at startup (as it
should) but never goes out (as it should) after just a few seconds of
running. When the engine is cold, the light goes out just after
starting. But  if the engine has been run - and you stop then start it
up again right away - that silly light comes on and never goes off -
just blinks, blinks and blinks. Makes me worry about coolant, even when
I know there should be no problem.  I've checked the sensor in the
expansion tank and it's OK. So what else - and how else - do  I check,
and if I need to replace something - what is it?

Thanks,
