It 'doesn't' operate properly, hence the overheating....

Bill,
The OP could also toss the thermostat into a pot of boiling water
to see if it opens fully.

The WJ's v8 has a electricly driven fan in addition to the mechanically

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
