The internal combustion engine cooling thermostat maintains the temperature of the engine near its optimum operating temperature by regulating the flow of coolant to an air cooled radiator. It operates mechanically, using a sealed chamber containing a wax pellet that melts and expands at a set temperature. Once the optimum operating temperature is reached, the thermostat progressively increases or decreases its opening in response to temperature changes, dynamically balancing the coolant recirculation flow and coolant flow to the radiator to maintain the engine temperature in the optimum range. The thermostat is generally found next to the vehicle's radiator and engine and plays the role of an engine valve. A damaged BMW 323i Thermostat will likely cause your vehicle to become overheated, causing it to damage the engine. Behr's replacement thermostat assembly for the 2001-2004 BMW 323i will restore harmony and order to the engine's temperature.
