John,
I wouldn't recommend running without a thermostat. A thermostat allows the
engine to maintain a constant, normal temperature (determined by the set-point
of the thermostat) and ALSO allows for the coolant in the radiator to cool down.
By running without the thermostat, what happens is the water/colant circulates
constantly without having any "cool down" time in the radiator. The w/c keeps
getting hotter and hotter.
