Contains 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 203 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.

What can I say? It's a new Stant thermostat. I installed it on my 2004 Dodge Ram Hemi when changing out the water pump. It is well made and fit perfectly in the water pump cut out. Just bolt on the thermostat housing, no gasket is required (I bought one but didn't need it. There's no additional gasket from the factory either). It seals with rubber around the thermostat. It's set for 203 degrees like the OEM. After installing it, my temp. gauge needle went to the same position as it did with the old one. I don't know why and there aren't any instructions but I have read that the little brass tit on the thermostat is supposed to be installed in the up position (12 o'clock or towards the hood. Maybe it's so any air bubbles can get out of the system.
This item fits exactly as designed in my 2006 300C Hemi 5.7. My previous thermostat had a blown seal. This new thermostat is particularly nice since it comes with the outer gasket that most of these thermostats don't come with. The car runs (according to the instrument cluster) at 197 degrees which is within the threshold for the PCM to properly control coolant flow at the factory level.
This T-Stat comes with the silicone seal, so you do not need a gasket. I was getting some seepage from the water outlet on my Ram 1500, I removed my old T-Stat, and seal, and dropped this in and no more leakage. Easy install, and working perfect!
