Temperature Sender

[njsteve]

The coolant is flowing (thermostat is open) and the car is idling with no airflow over the fins so I don't believe that the cooling effect of the radiator would account for the 30 degree temperature discrepency. I will try mounting the actual mechanical gauge in the same cyl head spot next.

If you all recall, I had this same problem with the SW electric temp sender and gauge in my hemi Charger until I replaced it with a mechanical gauge and finally got an accurate reading.
