Note: If your ISM/ISN/ISX/QSX engine is experiencing coolant temperature gauge cycling, replace your existing thermostat with this Cummins 4318947 180 degree thermostat. 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 the engine performance.

The Cummins 4318947 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 overheat condition. If you are currently experiencing any of these symptoms, it's time to replace the Cummins thermostat 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. Only Genuine Cummins parts come with a full factory warranty, giving you peace of mind and financial protection.
