🌡️ Superstat Premium Stainless Steel Thermostat by Stant-45119 Review

The thermostat works the same as replacing a Delco air conditioner. It doesn't maintain a constant temperature like the original did. 5.7 Vortec engines are prone to spark plug fouling if the engine is not warmed up in cold weather. Therefore, it is important to have a thermostat that maintains the temperature of the stay.

After two years, which is less than 15,000 miles on my Silverado, this unit stopped working.

It's a good investment and will help your engine run more efficiently.

Updated: I've since learned that my thermostat AND the dash temp sensor failed almost simultaneously. This thermostat works perfectly - I confirmed this by hooking up an OBD sensor and reading the actual temperature from the car's computer, not the temp sensor, and it was accurate. We apologize for the initial erroneous review. Original: I bought this as a 195 degree thermostat to replace the one open stuck in my Chevy pickup. It fits and works perfectly, but only regulates the temperature to…
