BEFORE YOU ORDER

Make the right match.

  1. Photograph the existing engine data plate and include the truck VIN.
  2. Have the installer compare controls, emissions equipment and required accessories.
  3. Ask whether the quote covers a complete engine or a more limited assembly.
Is any ISX15 engine suitable for my truck?
No. Engines sharing the ISX15 name can have application and configuration differences. Use the serial number, VIN and installer’s requirements to confirm the particular replacement.
What should an ISX15 listing include?
Look for the stock number, serial identification, known mileage or hours, condition notes, available inspection information and a clear list of supplied components.
Can I request an ISX15 that is not currently listed?
Use Find My Part with your current engine serial number, VIN and preferred package. The specialist can review your request against available and incoming inventory.
