Found something new on a Healey engine

[Jerry]

Attached is a picture of what looks like a sender unit that replaced a freeze plug in a Bj8 motor. I have never seen one of these before but it should work as a sender to a temperature gauge. Has anybody seen this in a Healey motor before?

There are two wires inside the slot.

block heater, I did not think of that! I bet it is pretty corroded inside now.

Looks like it is just in one of the Freeze plug holes. I think if you remove it you should be able to replace the freeze plug.
