My 1974 S2 seems to always run a bit hot according to the gauge. Normally the gauge stabilizes at the “l” in “normal” during regular driving. I have not had any issues with lost or boiling coolant and the car runs fine.
The other day I turned the ignition key to the “ACC” position and listed to the fuel pumps working and noticed that the temperature gauge rose to the “m” in “normal”. This was with a cold engine (20C) that wasn’t even running. I drove away, and as usual the temperature stabilized at “l”.
Do you believe that the gauge stabilizing at “m” with a cold, non-running engine could be an indication of a faulty temperature sender or is it incorrect to read the temperature on the gauge when the engine is not running?
