How to check if you own a 03-04.5 Dodge 6.7L Cummins 305HP?
- Check your VIN number. The 8th digit on VIN number is marked with a 6
- Check your solenoid - On the top left corner of the solenoid, there will be a three digit number - 018, 113, 210, 235, 250, 255, 503
- Check your nozzle - Clean the injector nozzle enough to where you can see the tiny spray orifices. There should be 8 spray atomizer holes. Use a magnifying glass.
