Your BMW Z3 engine needs to warm up as it starts its operation. Thus, the thermostat provides control for your engine's warm-up period. It is generally found between the engine and the radiator and stays closed during engine warm-up. If a thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the suitable running temperature is achieved. The range for your thermostat depends on the type of your engine, load requirements, the weather, and other factors.
