This 180 Degree Cummins Thermostat Kit is a direct OEM replacement 180 Degree Thermostat and Thermostat Seal for your Cummins Diesel engine.
The Cummins 180 Degree Thermostat allows low-temperature coolant from the radiator into the engine to keep the operating temperature within a predetermined range. Operating a Cummins diesel 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 below the correct operating temperature or overheat. If you are currently experiencing any of these symptoms its time to replace the Cummins 180 Degree Thermostat Kit yourself to alleviate this issue.
