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.

Love it in my 03 Dakota. A lot cheaper than the OEM design and no issues for me. Dropped this into my 2003 dodge Dakota without any issues. It’s not the same as the OEM design but it seem to work just fine. I did drill a 1/16th hole to allow some coolant to weep through like the OEM design has and while it does not close the passage like the OEM does I have so far had zero issues. In fact my truck runs nice and cool and I live in Oklahoma and was able to make a trip out to Phoenix, Los Angeles, San Francisco, Reno, across Nevada and Utah along Highway 50 to Denver and…
Idle is good. Really no change from standard OEM thermo East to install on my 2001 Jeep Cherokee. Runs way cooler than standard higher degree thermostat. I live in a hot climate, so does very well with AC on in hot weather. Idle is good. Really no change from standard OEM thermo.
The Best – Works Great with BBC I have a high performance 454 engine with a regular fan and brass radiator. I’ve been using the Stant 180 degree SuperStat with all of my Chevy engines. For the 454, we ran the engine at 3,000 RPMs for over 20 minutes for the initial engine break-in, and it did not get close to over-heating. I did drill two small 1/16″ holes in the thermostat housing to allow the release of any air that might have been trapped in the system. Not sure if it’s an old wive’s tale to do this, but apparently it…
