your engine won't die prematurely, if that is what you are worried about.

a thermostat prevents coolant inside the engine block, from circulating into the radiator.
as a result, your engine gets up to its optimal working temperature, faster.
while that engine is cool, the computer gives it more fuel, sort of "choked".
as a result, engines running cooler than their optimal working temperature, consume more fuel.

bottomline, a working thermostat helps you save on fuel, and lessens pollution.
