These Cummins 170 Degree Replacement Thermostat applications:

Note: If your Cummins NT-855 engine is experiencing coolant temperature gauge cycling, replace your existing thermostat with this Cummins 135675 170 thermostat. The new Cummins 135675 thermostat provides a slower coolant response rate to reduce dramatic engine temperature cycling. This slower engine response rate does not affect engine performance. This OEM Cummins Thermostat has an operating range of 170 to 185 Degrees.

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 overheating condition. If you are currently experiencing any of these symptoms, it's time to replace the Cummins 170-Degree Thermostat yourself to alleviate this issue.
