Detailed Product Information

The Four Seasons Coolant Temp Sensor line focuses on direct-fit cooling system sensors for vehicles that rely on accurate coolant temperature input for engine management and gauge operation. Part number 37879 is specified for many Mercedes-Benz models, including Sprinter, C300, E350, GL450, ML350, and SLK applications, along with select Dodge Sprinter 2500 and 3500 and Jeep Grand Cherokee coverage. This part cross-references URO 0009056102 for the same application. Four Seasons 37879 is a practical OE-style replacement when the original coolant temperature sensor has failed or is sending incorrect readings.
