Product Overview
The temperature sender converts coolant temperature into an electrical signal for the gauge, warning circuit or controller. If its internal resistance element fails, the machine can show no temperature reading, an implausible reading or a false warning while actual engine temperature is normal.
Cross-reference listings identify 3015238 on K19/KTA19/QSK19 families and specify a 1/2-inch NPT thread. Because sending units can share the same thread while using different calibration curves, matching 3015238 is essential.

Before You Order
- Match 3015238 rather than thread size alone; electrical calibration matters.
- Diagnose actual coolant temperature and wiring/gauge operation before assuming the sender is faulty.
Frequently Asked Questions
Can the sender cause overheating?
It reports temperature; it does not control coolant flow. A faulty sender can create an incorrect indication, while real overheating needs mechanical diagnosis.
Should thread sealant be used?
Follow Cummins/service guidance because some senders rely on their threaded body for electrical ground; excessive insulating sealant can affect operation.
Compatibility can vary by engine, serial number and equipment configuration. Match the original part number and physical configuration whenever possible before ordering.
