If you mean that you are running your engine without a thermostat in your coolant system, this is a very bad idea. By not allowing your engine to reach normal operating temp. quickly you could see engine damage due to condensation in the crankcase, acidity,and sludge. Fuel usage is also affected. Your oil can also contain fuel dilution. Although you live in FLA. you would have little or no heat from your heater. Once again a bad idea to run a car without a thermostat even if it is a Chevy...
