Stant 45858 SuperStat Thermostat - 180 Degrees Fahrenheit
The Stant SuperStat Themostat out performs the Original Equipment themostat. Unlike the OE themostats that continually open and close to achieve the proper operation temperature and flood the engine with coolant, the Stant SuperStat has a patented V-notch, non linear design that reduces cycling by precisely metering the amount of coolant needed.  the V-notch provides 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 temperture is reached.  The benefits of proper engine temperature control are: efficient engine operation, prolonged engine life, reduced oil consumption, improved fuel economy and improved emmisions.   The SuperStat uses a high flow venturi for maximum cooling capacity during high temperature high load operation, and employes a patented Weir Valve, for percision flow metering during cold weather light load operation, to ensure stable temperature control under all conditions.The power element of the SuperStat is comparable to those used in the heavy duty trucking industry.  It employs an actuator piston that is 25% larger than our standard themostat and 55% larger than competitive products.  This larger heavy piston duty delivers one and one half times as much power as competitive stats for enhanced durability and longer life.  The flange on the SuperStat is 33% thicker than our standerd product and 43% thicker than competitor's themostats for added strength and longer life.The operating spring is 50% stronger than on standard themostats.  This helps return the Superstat to the closed position and provent cold running even under the most adverse operating conditions.
