Unlike conventional thermostats that continually open and close to achieve the proper operating temperature and flood the engine with coolant, the Stant SuperStat® thermostat has a unique v-notch, non-linear design that reduces cycling by precisely metering the amount of coolant needed to maintain proper operating temperature.
Features:
V-notch provides a small initial flow. As the engine heats up, the v-notch gradually opens wider, metering coolant into the system until the desired engine temperature is reached.
High strength stainless steel flange is burnished to a bright finish for additional stress relief and added corrosion resistance.
Thicker than most competitor thermostats and our standard reverse poppet thermostat for added strength and longer life.
The power element of SuperStat® is comparable to those used in heavy-duty trucks. Its actuator piston is larger in diameter than the standard thermostat and competitive product. This larger piston delivers 1 1/2 times the power of our standard thermostat and almost 2 1/2 times as much power as the competition for enhanced durability and longer life.
The opening spring of the Stant SuperStat® thermostat is designed with a load that is 50% stronger than our standard reverse poppet thermostat. This heavy-duty spring helps return the thermostat to the closed position and prevent cold running, even under the most adverse conditions.

What Temperature Thermostat Do I Need?
Thermostats have a “rated” temperature (such as 180F or 195F). This is the temperature the thermostat will start to open, releasing heated coolant from the engine into the radiator. The thermostat will fully open once the coolant gets another ten or fifteen degrees warmer.
OE TEMPERATURE
These thermostats match the OEM-specified temperature rating for the vehicle. Manufacturers recommend an OE temperature thermostat for most engines, especially for:
Modern engines with computers that use the coolant temperature to help control the fuel, emissions and other important systems
ALTERNATE TEMPERATURE
These thermostats have a temperature rating below (cooler than) the OEM-specified temperature rating for the vehicle. This option may make sense for use in:
Modified Engines
Performance Applications
Older / Classic Vehicles
Cooling System Maintenance | Tips & Tools
Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:
Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
Consider replacing the Radiator Hoses (and Hose Clamps) and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
