I have been wondering whether my coolant level sensor is faulty, since I
don't remember every seeing it come on when I've done coolant flushes, etc.
My understanding was that the sensor is just a conductivity sensor, so that
unplugging it should make the system think the coolant is empty.  However,
when I unplugged mine, and then started the van, the light flashed for a few
seconds like always, then went out as always, seemingly suggesting that the
level is fine.  What could be going on here?

Thanks,
Wes
