The new Cummins 4318948 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 4318948 Thermostat on your ISM/ISN/ISX/QSX 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 thermostat to alleviate this issue.
