Mal, thanks for that photo. Along with O_D's suggestion of a sensor being in the upper tank, I'm leaning toward doing something in that thermostat neighborhood.

Can think of two approaches. One is a thick plate shaped like the housing base and drilled and tapped for the sensor to locate between the head the thermostat housing. Advantage there is no mod and easily removed.

An easier approach if there are repro outlets available for the senior engine might be forget the plate but use a modern thermostat which should fit farther up inside the housing than the old bellows type. Not sure about the retainer though. If the wire could be used or solid retainer slotted enough, perhaps the hole and threads could be cut in the side of housing somewhere fairly low. Anyone running a modern thermostat have any idea how much open space is clear just below the thermostat?

Downside with either is still accuracy when the thermostat is closed -- but that would be a condition that likely would not be the case anytime the temperature was suspect and needed confirmation.

Anyone see an issue with either approach? If not, I may try something.
