Description
If your coolant temperature sensor in your 5.9L Cummins is not able to accurately determine the temperature of your coolant, it will send faulty readings to your ECM, which can cause your fan to not engage at the correct time, possibly even leading to overheating. This is a genuine Cummins direct replacement designed to meet or exceed factory specifications.
