I know that but the electrical one has no where near the cooling
capacity of the engine driven one. For it to do so it would require
more electrical power than the cars system can produce and sustain

Is the temp gauge electrical? I have not seen anybody suggest an
electrical/gauge problem. Maybe I missed it.

Years ago a buddy had an old Dart with odd overheating symptoms. He
temporarily rigged a ( calibrated, borrowed from work ) digital temp gauge
and determined there really was no overheating. I don't recall whether he
identified the exact problem but he changed the gauge and rewired. Problem
solved.

On the old Darts if you lost instrument panel ground all the gauges would
self destruct. Nasty problem.

Hi Herb,
Of course, but my guess was it was stuck half open to run normally
until he pulled a hill. I have found many that way on my own cars
shortly before I have to make sure the engine reaches full operating
temperature at smog inspection.
