Sign of a faulty t-stat is if the car takes a long time to reach normal operating temp. Your needle should be at the halfway point within 5-10 minutes of driving. Also check the top radiator hose. Pressure and coolant flow should exist there once operating temp is reached, if the t-stat is opening properly.
