Specs At A Glance

Good To Know

Q: Can this sensor be used on non-Cummins engines? A: It is designed specifically for Cummins engines listed; using it on other brands may require thread adapters and electrical compatibility checks.

Q: How do I test the sensor before installation? A: Use a multimeter to measure resistance at known temperatures (e.g., 200°F) and compare to the OEM specification for 3915329.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
