Update:
Since my last post the erratic nature of my water temp came back. Someone suggested it could be caused by a short in the wires, and noticed there was teflon tape around the threads of the water sensor. It needs a ground through the block, so we took the teflon tape off, cleaned the sensor up and screwed it back in the block. We burped it again and started driving. Still erratic for a few minutes, and then the gauge or the sensor gave up and dropped to zero (well, really 60C). This is an Autometer Cobra style electric model. We will reorder a gauge and sensor and restart the whole process. I'll keep you posted.
