The Cummins 3928639 Thermostat on your ISC 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.

If you are currently experiencing any of these symptoms, it's time to replace the Cummins thermostat to alleviate this issue.
