Note: If your Cummins Detroit Diesel NH and NT-855 engine is experiencing coolant temperature gauge cycling, replace your existing thermostat with this Cummins 3064453 173 thermostat. The new Cummins 3064453 thermostat provides a slower coolant response rate to reduce dramatic engine temperature cycling. This slower engine response rate does not affect engine performance.
The Cummins Thermostat on your Cummins engine allows low-temperature coolant from the radiator into the engine to keep the operating temperature within a predetermined range. Operating a Cummins engine with a bad thermostat will cause the thermostat to get stuck in the open or closed position. A defective thermostat will cause the engine to operate either below the correct operating temperature or above it leading to an overheat condition. If you are currently experiencing any of these symptoms, it's time to replace the Cummins 173 Degree Thermostat yourself to alleviate this issue.
The use of Genuine Cummins parts means you get a precision design, state-of-the-art manufacturing, and diligent testing which ensures optimum engine performance at the Cummins factory-specified level.
