FAQ

WILL THIS FIT MY 2003–2004 5.9L CUMMINS RAM?

Yes—this is the OE ECT sensor for most 2003–2004 Ram 2500/3500 5.9L ISB common-rail trucks (confirm by VIN/ESN).

IS THIS THE SAME AS BOSCH 0281002471?

Yes—Bosch 0281002471 is a common cross-reference for Cummins 4897224. We still recommend verifying by ESN or the number on your old sensor.

WHAT SYMPTOMS POINT TO A BAD COOLANT TEMP SENSOR?

Erratic temp gauge, fan engagement issues, rich/lean fueling, hard starts, and overheating with related ECM codes.

DO I NEED ANY GASKETS OR SEALS?

The sensor seals via its threaded interface (M14×1.5). Follow service manual guidance on sealant and torque.

WILL THIS WORK ON INDUSTRIAL ISB/QSB ENGINES?

Common on Euro 3 ISB/QSB 3.9/5.9L applications—always verify by ESN for industrial/off-highway engines.
