Unlike conventional thermostats that continually open and close to achieve the proper operation temperature and flood the engine with coolant, the Stant® SuperStat™ thermostat has a patented V-notch, non linear design that reduces cycling by precisely metering the amount of coolant needed.
The V-notches provide a small initial flow. As the engine heats up, the V-notches gradually open wider, metering coolant released into the system until the desired engine temperature is reached.
