Description
Like most people, you probably think all thermostats are alike. But Stant brand thermostats are different. They're the thermostats you ask for by name. And the superiority of Stant thermostats shows in the way they consistently outperform the competition. They are, quite simply, the best engineered thermostats in the world and here's why. The heart of the Stant brand thermostat is the ELAC heat motor. The unique properties of the heat motor result in a consistent and precise response to the cooling system's needs. This is achieved through the use of a precisely formulated, thermally expansive wax fill that is calibrated to operate within OEM requirements. The Stant heat motor is powered by a precisely formulated thermal responsive wax pellet in a heat conducting copper cup equipped with a stainless steel piston inside an elastomeric boot. The exact length of the stainless steel piston assures the prompt and precise operation of the thermostat valve. Each manufacturing process is rigidly controlled with world-class quality controls. Then a 100% calibration is conducted for each heat motor to guarantee quality and performance. Finally, the heat motor is placed in a stainless steel assembly consisting of a valve, flange, bridge and spring. The completed assembly provides a securely sealed, heat responsive valve that keeps engine temperatures within original equipment specifications. Our reverse poppet thermostats are engineered with a self-cleaning, self-aligning stainless steel valve. It's no wonder Stant is the original equipment choice of many automakers. So why take chances with anything less? Buy the world's best engineered thermostats from Stant.3. Gates 33479 195f Thermostat

Only Fail-Safe is designed to lock in the open position when overheating occurs due to a failing cooling system component. This allows maximum coolant flow, thus preventing expensive engine damage.6. Stant 45858 SuperStat Thermostat - 180 Degrees Fahrenheit
Feature
SuperStat exceeds OE performanceContains larger piston and springs that OE themostats
Better flow control than OE themostats
Stainless steel flange for longer life and strength
Use when you want 180 Degrees Fahrenheit
Description
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.7. Stant 45859 SuperStat Thermostat - 195 Degrees Fahrenheit
