correct operating temp.

[Daniel Neuman <dneuman@stars.sfsu.edu>]

Hello All,
I'm just trying to fine tune my thermostat setting on my 
electric fan.  What is the correct operating temp when cruising?
I know that the thermostat(not the electric one the water one) is a
180 degree model.  I also believe that around this temp is the correct
operating temp for the engine.  Whats a reasonable range under normal
semi-spirited driving conditions?  I am trying to decide when my electric
fan should turn on to help cool the engine.

                TIA
