Stant 49279 SuperStat 192° F Thermostat, medium

The Stant SuperStat Thermostat out performs the Original Equipment thermostat. Unlike the OE thermostats 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 temperature is reached. The benefits of proper engine temperature control are: Efficient engine operation, prolonged engine life, reduced oil consumption, improved fuel economy and improved emissions. The SuperStat uses a high flow venturi for maximum cooling capacity during high temperature, high load operation, and employs a patented weir valve, for precision 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 percent larger than Stant's standard thermostat. The flange on the SuperStat is 33 percent thicker than Stant's standard product for added strength and longer life. The operating spring is 50 percent stronger. This helps to return the SuperStat to the closed position and prevent cold running even under the most adverse operating conditions.
