## Overview

The Stant 45778 SuperStat thermostat outperforms standard OE models with a patented V-notch design for precise coolant metering at 180°F. Featuring a 55% larger actuator piston and a 33% thicker stainless steel flange, it delivers superior durability and engine temperature stability. Its stronger spring and advanced flow control optimize fuel economy, reduce emissions, and extend engine life under all driving conditions.

## Description

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 our standard thermostat and 55 percent 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 percent thicker than our standard product and 43 percent thicker than competitor's thermostats for added strength and longer life. The operating spring is 50 percent stronger than on standard thermostats. This helps return the Superstat to the closed position and prevent cold running even under the most adverse operating conditions.
