Ok, I give up. I added the extra
oil then Took a 15 minute drive around town today. The temp gauge only fluctuated from the low (bottom of the scale is 140) to around 145. I'd expect it to show warmer than that after 10 minutes of street driving. Maybe it takes longer that that to get more heat into 8 quarts of
oil. I'll be at the track tomorrow and it is supposed to be around 90 degrees farenheit.
Connector is snug. Wires show continuity. Unless it is a bad sensor or gauge, I don't know what else. Next week I'll pull the sensor to check it with the boiling water trick.
