THERMOSTAT
PREMIUM 180 Degree
This premium thermostat will fit 1928-1991 GM engines with 2-1/8" openings. 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 patented v-notch, non-linear design that reduces cycling by precisely metering the amount of coolant needed to maintain proper operating temperature. The v-notch provides a small inital flow. As the engine heats up, the v-notch gradually opens wider, metering coolant into the system until the desired engine temperature is reached.
The high strength stainless steel flange is burnished to a bright finish for additional stress relief and added corrosion resistance.
Superstat premium thermostats have:
Heavier frames and springs Larger heat motors Patented Weir valves
The unique Weir valve provides a higher flow of coolant to the radiator than any other thermostat on the market. The early flow of coolant minimizes the "cycling" of temperature allowing the engine to run a steady temperature, resulting in higher efficiency. |
