Technically you can, but the thermostat is not going to affect overheating unless defective. What the thermostat does is keep the coolant from flowing until your engine reaches a better operating temperature, then it opens to let coolant flow to wick heat from the engine and cool off in the radiator. Even if you did not have a thermostat, the engine would still overheat because the issue is either your engine is generating too much heat or your cooling system is not dumping enough heat in the first place.(Unless the thermostat is stuck in the closed position)
